Jackson NASA Headquarters building in Washington. NASA/Keegan Barber

During an event Thursday, NASA and the National Association for the Advancement of Colored People (NAACP) signed a Space Act Agreement to increase engagement and equity for underrepresented students pursuing science, technology, engineering, and mathematics (STEM) fields and to improve access to agency activities and opportunities.

“NASA and the NAACP share a longstanding commitment to attracting more diverse students to STEM education and ultimately careers,” said Shahra Lambert, senior advisor for engagement and equity, NASA headquarters. “This agreement reaffirms that commitment and solidifies a partnership that will enable us to expand opportunities for more students of color to build their STEM identity and gain real-world experience through NASA STEM education, mentorship, and career awareness. With the NAACP’s help we’ll be able to truly impact young minds who will be our future scientists, engineers, explorers and more.”

As part of the agreement, the NAACP will incorporate NASA STEM lessons, content, and themes into its Afro-Academic, Cultural, Technological and Scientific Olympics (ACT-SO) achievement program, which is a series of competitions where students compete for scholarships and other incentives in areas ranging from performing and culinary arts to business and STEM. In turn, NASA will provide guidance on programming, participate in information sharing, provide mentorship, and facilitate tours of NASA facilities when appropriate.

“Much like NASA, brave, brilliant, Black women were critical to the success of the NAACP,” said Leon W. Russell, Chairman of the NAACP Board of Directors. “For years, we’ve worked to increase the number of diverse STEM students by providing scholarships and establishing key initiatives. Through our ACT-SO program and this new partnership with NASA, both organizations will make even greater progress to help pave the way for more Katherine Johnsons and Mary Jacksons. By enacting today’s agreement, we hope to increase the number of Black and underrepresented students in the STEM fields and help them reach for the stars.”

While initial efforts will be led by NASA’s Office of STEM Engagement, the umbrella agreement also allows for further collaboration and partnership in the future. Specifically, the agency and the NAACP will look to support certain areas of NASA’s Equity Action Plan.

NASA works to explore the secrets of the universe and solve the world’s most complex problems, which requires creating space for all people to participate in and learn from its work in space. Providing access to opportunities where young minds can be curious and see themselves potentially at NASA and beyond is how the agency will continue to inspire the next generation of STEM innovators.

NASA astronaut Tracy C. Dyson, accompanied by Roscosmos cosmonauts Nikolai Chub and Oleg Kononenko, will depart from the International Space Station aboard the Soyuz MS-25 spacecraft, and return to Earth.

Dyson, Chub, and Kononenko will undock from the orbiting laboratory’s Prichal module at 4:37 a.m. EDT Monday, Sept. 23, heading for a parachute-assisted landing at 8 a.m. (5 p.m. Kazakhstan time) on the steppe of Kazakhstan, southeast of the town of Dzhezkazgan.

NASA’s live coverage of return and related activities will stream on NASA+ and the agency’s website. Learn how to stream NASA content through a variety of platforms, including social media.

A change of command ceremony also will stream on NASA platforms at 10:15 a.m. Sunday, Sept. 22. Kononenko will hand over station command to NASA astronaut Suni Williams for Expedition 72, which begins at the time of undocking.

Spanning 184 days in space, Dyson’s mission includes covering 2,944 orbits of the Earth and a journey of 78 million miles. The Soyuz MS-25 spacecraft launched March 23, and arrived at the station March 25, with Dyson, Roscosmos cosmonaut Oleg Novitskiy, and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.

Kononenko and Chub, who launched with O’Hara to the station on the Soyuz MS-24 spacecraft last September, will return after 374 days in space and a trip of 158.6 million miles, spanning 5,984 orbits.

Dyson spent her fourth spaceflight aboard the station as an Expedition 70 and 71 flight engineer, and departs with Kononenko, completing his fifth flight into space and accruing an all-time record 1,111 days in orbit, and Chub, who completed his first spaceflight.

After returning to Earth, the three crew members will fly on a helicopter from the landing site to the recovery staging city of Karaganda, Kazakhstan. Dyson will board a NASA plane and return to Houston, while Kononenko and Chub will depart for a training base in Star City, Russia.

Slime Mold Can Teach Us About the Cosmic Web

Universe Today - Thu, 09/19/2024 - 5:59pm

Computers truly are wonderful things and powerful but only if they are programmed by a skilful mind. Check this out… there is an algorithm that mimics the growth of slim mold but a team of researchers have adapted it to model the large scale structure of the Universe. Since the Big Bang, the universe has been expanding while gravity concentrates matter into galaxies and clusters of galaxies. Between them are vast swathes of empty space called voids. The structure, often referred to as the cosmic web.

The cosmic web is the largest scale structure of the universe and it’s made up of filaments of galaxies and dark matter that stretch across the gulf of space. The filaments connect galaxy clusters with immense voids in between. The web-like structure has formed as a result of the force of gravity pulling matter together since the beginning of time. Studying the cosmic web helps us to piece together the evolution of the universe, how matter is distributed and the relationship with dark matter.

Since the early 80’s it’s been known that the nature of a galaxy and its environmental properties has an impact on how it grows and evolves. The exact nature and how this happens is still the cause of many debates. A team of researchers believe they may have demonstrated how galaxies evolve using a slime algorithm!

The team, led by Farhanul Hasan, Professor Joe Burchett and eight co-authors, published their findings ‘Filaments of the Slime Mold Cosmic Web and How they Affect Galaxy Evolution’ in August’s edition of the Astrophysical Journal.  In the paper they report how the mold algorithm has helped to unlock mysteries of the cosmos. 

Burchett recommended the slime mold algorithm could be used for an astrophysical application. Hasan worked with Burchett and altered the algorithm to help them visualise the cosmic web. The team worked with graphics rendering expert Oskar Elek to use the slime mold algorithm. The mold algorithm was designed to mimic slime mold that could find its own food by reforming itself into a structure much like the cosmic web. It took the team several years to complete their work. 

In shaping the Universe, gravity builds a vast cobweb-like structure of filaments tying galaxies and clusters of galaxies together along invisible bridges hundreds of millions of light-years long. A galaxy can move into and out of the densest parts of this web throughout its lifetime. Credit: Volker Springel (Max Planck Institute for Astrophysics) et al.

The result produced far more detailed discrete structures than the old method according to Hasan. He added ‘I didn’t know how well it was going to work or not work, but I had a hunch the slime mold method could tell us much more detailed information about how density is structured in the universe, so I decided to give it a try.’

Of the conclusion, Hasan and team found that the impact on galaxies seems to have taken the proverbial u-turn. In earlier epochs, the growth of a galaxy was stimulated by proximity to larger structures. In the near universe, and therefore in cosmologically recent times, we see that galaxy growth is limited by proximity to larger structures. This wasn’t possible without the modified slime mold algorithm. We can now map out the gas around the real universe using the algorithm across many different times to help understand how the web has changed and the universe evolved.

55 Years Ago: Celebrations for Apollo 11 Continue as Apollo 12 Prepares to Revisit the Moon

NASA - Breaking News - Thu, 09/19/2024 - 5:31pm

In September 1969, celebrations continued to mark the successful first human Moon landing two months earlier, and NASA prepared for the next visit to the Moon. The hometowns of the Apollo 11 astronauts held parades in their honor, the postal service recognized their accomplishment with a stamp, and the Smithsonian put a Moon rock on display. They addressed Congress and embarked on a 38-day presidential round the world goodwill tour. Eager scientists received the first samples of lunar material to study in their laboratories. Meanwhile, NASA prepared Apollo 12 for November launch as the astronauts trained for the mission with an increased emphasis on lunar science. Plans called for additional Moon landings in 1970, with spacecraft under construction and astronauts in training.

Apollo 11

For Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin, their busy August 1969 postflight schedule continued into September with events throughout the United States and beyond. These included attending hometown parades, dedicating a stamp to commemorate their historic mission, unveiling a display of a Moon rock they collected, addressing a Joint Meeting of Congress, and visiting contractor facilities that built parts of their rocket and spacecraft. They capped off the hectic month with their departure, accompanied by their wives, on a presidential round-the-world goodwill tour that lasted into early November.

On Sep. 6, each astronaut appeared at hometown events held in their honor. Apollo 11 Commander Armstrong’s hometown of Wapakoneta, Ohio, welcomed him with a parade and other events.  Montclair, New Jersey, held a parade to honor hometown hero Lunar Module Pilot (LMP) Aldrin. And New Orleans, Louisiana, the adopted hometown of Command Module Pilot (CMP) Michael Collins, honored him with a parade.

Blount display an enlargement of the stamp commemorating the first Moon landing. Right: Aldrin, left, Collins, and Armstrong examine a Moon rock with Smithsonian Institution Director General of Museums Frank A. Taylor.

Three days later, the astronauts reunited in Washington, D.C., where they appeared at the dedication ceremony of a new postage stamp that honored their mission. The U.S. Postal Service had commissioned artist Paul Calle in 1968 to design the stamp. The Apollo 11 astronauts had carried the stamp’s master die to the Moon aboard the Lunar Module (LM) Eagle and after its return to Earth the Postal Service used it to make the printing pages for the 10¢ postage stamp. At the National Postal Forum, Armstrong, Collins, and Aldrin unveiled the stamp together with Postmaster General Winton M. Blount, and each astronaut received an album with 30 of the “First Man on the Moon” stamps. On Sep. 15, the crew returned to Washington to present a two-pound rock they collected in the Sea of Tranquility during their historic Moon walk to Frank A. Taylor, the Director General of Museums at the Smithsonian Institution in Washington, D.C. The rock went on public display two days later at the Smithsonian’s Arts and Industries Building, the first time the public could view a Moon rock.

Agnew and Speaker of the House John W. McCormack seated behind them. Middle: Apollo 11 astronauts’ wives Joan Aldrin, left, Patricia Collins, and Janet Armstrong receive recognition in the Visitors Gallery of the House Chamber. Right: The Apollo 11 astronauts and their wives cut at a cake at a reception at the Capitol.

With their wives observing from the Visitors Gallery of the House of Representatives, on Sep. 16 Armstrong, Aldrin, and Collins addressed a Joint Meeting of Congress. In this same chamber in May 1961, President John F. Kennedy committed the nation to land a man on the Moon and return him safely to the Earth before the end of decade. In a sense, the astronauts reported on the safe and successful completion of that challenge. Speaker of the House John W. McCormack introduced the astronauts to the gathering, as Vice President Spiro T. Agnew looked on. Each astronaut reflected on the significance of the historic mission.

Armstrong noted that their journey truly began in the halls of Congress when the Space Act of 1958 established NASA. Aldrin commented that “the Apollo lesson is that national goals can be met when there is a strong enough will to do so.” Collins shared a favorite quotation of his father’s to describe the value of the Apollo 11 mission: “He who would bring back the wealth of the Indies must take the wealth of the Indies with him.” Armstrong closed with, “We thank you, on behalf of all the men of Apollo, for giving us the privilege of joining you in serving – for all mankind.” After their speeches, the astronauts presented one American flag each to Vice President Agnew in his role as President of the Senate and to Speaker McCormack. The flags, that had flown over the Senate and House of Representatives, had traveled to the Moon and back with the astronauts. Speaker McCormack recognized the astronauts’ wives Jan Armstrong, Joan Aldrin, and Pat Collins for their contributions to the success of the Apollo 11 mission.

On Sep. 26, Armstrong and Collins visited two facilities in California of North American Rockwell (NAR) Space Division, the company that built parts of the Saturn V rocket and Apollo 11 spacecraft. First, they stopped at the Seal Beach plant that built the S-II second stage of the rocket, where 3,000 employees turned out to welcome them. Armstrong commented to the assembled crowd that during the July 16, 1969, liftoff, “the S-II gave us the smoothest ride ever.” Collins added that despite earlier misgivings about using liquid hydrogen as a rocket fuel, “after the ride you people gave us, I sure don’t have doubts any longer.” About 7,000 employees greeted the two astronauts and showered them with confetti at their next stop, the facility in Downey that built the Apollo Command and Service Modules. Both Armstrong and Collins thanked the team for building an outstanding spacecraft that took them to the Moon and returned them safely to Earth. The astronauts inspected the Command Module (CM) for Apollo 14, then under construction at the plant.

On the morning of Sep. 29, a blue and white Boeing VC-137B presidential jet touched down at Ellington Air Force Base in Houston. Neil and Jan Armstrong, Buzz and Joan Aldrin, and Mike and Pat Collins boarded the plane and joined their entourage of State Department and NASA support personnel. They departed Houston for Mexico City, the first stop on the Apollo 11 Giantstep goodwill world tour. They didn’t return to the United States until Nov. 5, having visited 29 cities in 24 countries, just nine days before Apollo 12 took off on humanity’s second journey to land on the Moon.


Distribution of Apollo 11 lunar samples to scientists at the Lunar Receiving Laboratory at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston.

Back in Houston, distribution to scientists of samples of the lunar material returned by the Apollo 11 astronauts began on Sep. 17 at the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Daniel H. Anderson, curator of lunar samples at the LRL, supervised the distribution of approximately 18 pounds – about one-third of the total Apollo 11 lunar material – to 142 principal investigators from the United States and eight other countries according to prior agreements. The scientists examined the samples at their home institutions and reported their results at a conference in Houston in January 1970. They returned to the LRL any of the samples not destroyed during the examination process.

Apollo 12

In September 1969, NASA continued preparations for the second Moon landing mission, Apollo 12, scheduled for launch on Nov. 14. The Apollo 12 mission called for a pinpoint landing in Oceanus Procellarum (Ocean of Storms) near where the robotic spacecraft Surveyor 3 had touched down in April 1967. They planned to stay on the lunar surface for about 32 hours, compared to Apollo 11’s 21 hours, and conduct two surface spacewalks totaling more than 5 hours. During the first of their two excursions, the astronauts planned to deploy the Apollo Lunar Surface Experiments Package (ALSEP) and collect lunar samples. During the second spacewalk, they planned to visit Surveyor 3 and remove some of its equipment for return to Earth and collect additional lunar samples. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, CMP Richard F. Gordon, and LMP Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin continued intensive training for the mission.

Right: Apollo 12 astronauts Alan L. Bean, left, Richard F. Gordon, and Charles “Pete” Conrad pose in front of their Saturn V during the rollout to the pad.

On Sep. 8, the Saturn V rocket with the Apollo 12 spacecraft on top rolled out from Kennedy Space Center’s (KSC) Vehicle Assembly Building to Launch Pad 39A. The rocket made the 3.5-mile trip to the pad in about 6 hours, with Conrad, Gordon, and Bean on hand to observe the rollout. Workers at the pad spent the next two months thoroughly checking out the rocket and spacecraft to prepare it for its mission to the Moon. The two-day Flight Readiness Test at the end of September ensured that the launch vehicle and spacecraft systems were in a state of flight readiness. In addition to spending many hours in the spacecraft simulators, Conrad and Bean as well as their backups Scott and Irwin rehearsed their lunar surface spacewalks including the visit to Surveyor 3. Workers at NASA’s Jet Propulsion Laboratory in Pasadena, California, shipped an engineering model of the robotic spacecraft to KSC, and for added realism, engineers there mounted the model on a slope to match its relative position on the interior of the crater in which it stood on the Moon. Conrad and Scott used the Lunar Landing Training Vehicle (LLTV) at Ellington Air Force Base (AFB) near MSC to train for the final 200 feet of the descent to the lunar surface.

Middle: Conrad trains in the use of the Hasselblad camera he and Bean will use on the Moon. Right: Bean, left, and Conrad train with an engineering model of a Surveyor spacecraft.

With regard to lunar geology training, the Apollo 12 astronauts had one advantage over their predecessors – they could inspect actual Moon rocks and soil returned by the Apollo 11 crew. On Sep. 19, Conrad and Bean arrived at the LRL, where Lunar Sample Curator Anderson met them. Anderson brought out a few lunar rocks and some lunar soil that scientists had already tested and didn’t require to be stored under vacuum or other special conditions, allowing Conrad and Bean to examine them closely and compare them with terrestrial rocks and soil they had seen during geology training field trips. This first-hand exposure to actual lunar samples significantly augmented Conrad and Bean’s geology training. To highlight the greater emphasis placed on lunar surface science, the Apollo 12 crews (prime and backup) went on six geology field trips compared to just one for the Apollo 11 crews.

Middle: Wearing Biological Isolation Garments and assisted by a decontamination officer, standing in the open hatch, Apollo 12 astronauts await retrieval in the life raft. Right: The recovery helicopter hoists the third crew member using a Billy Pugh net.

Although the Apollo 11 astronauts returned from the Moon in excellent health and scientists found no evidence of any harmful lunar microorganisms, NASA managers still planned to continue the postflight quarantine program for the Apollo 12 crew members, their spacecraft, and the lunar samples they brought back. The first of these measures involved the astronauts donning Biological Isolation Garments (BIG) prior to exiting the spacecraft after splashdown. Since they didn’t carry the BIGs with them to the Moon and back, one of the recovery personnel, also clad in a BIG, opened the hatch to the capsule after splashdown and handed the suits to the astronauts inside, who donned them before exiting onto a life raft.

On Sep. 20, the Apollo 12 astronauts rehearsed these procedures, identical to the ones used after the first Moon landing mission, in the Gulf of Mexico near Galveston, Texas, using a boilerplate Apollo CM and supported by the Motorized Vessel (MV) Retriever. As it turned out, NASA later removed the requirement for the crew to wear BIGs, and after their splashdown the Apollo 12 crew wore overalls and respirators.

Apollo 13

Right: Apollo 13 backup crew members John W. Young, left, and Swigert in the CM for an altitude chamber test – Charles M. Duke is out of the picture at right.

Preparations for Apollo 13 continued in parallel. In KSC’s Manned Spacecraft Operations Building (MSOB), Apollo 13 astronauts completed altitude chamber tests of their mission’s CM and LM. Prime crew members Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise completed the CM altitude test on Sep. 10, followed by their backups John W. Young, Jack L. Swigert, and Charles M. Duke on Sep. 17. The next day, Lovell and Haise completed the altitude test of the LM, followed by Young and Duke on Sep. 22. At the time of these tests, Apollo 13 planned to launch on March 12, 1970, on a 10-day mission to visit the Fra Mauro highlands region of the Moon. To prepare for their lunar surface excursions, Lovell, Haise, Young, and Duke, accompanied by geologist-astronaut Harrison H. “Jack” Schmitt and Caltech geologist Leon T. “Lee” Silver, spent the last week of September in Southern California’s Orocopia Mountains immersed in a geology boot camp.

Apollo 14 and 15

Looking beyond Apollo 13, the Apollo 14 crew of Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell and their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle had started training for their mission planned for mid-year 1970. At the NAR facility in Downey, engineers prepared the CM and SM and shipped them to KSC in November 1969. Also at Downey, workers continued assembling the CM and SM planned for the Apollo 15 mission in late 1970. As events transpired throughout 1970, plans for those two missions changed significantly.

NASA management changes

On Sept. 25, NASA appointed veteran astronaut James A. McDivitt as the Manager of the Apollo Spacecraft Program Office at MSC. McDivitt, selected as an astronaut in 1962, commanded two spaceflights, Gemini IV in June 1965 that included the first American spacewalk and Apollo 9 in March 1969, the first test of the LM in Earth orbit. He succeeded George M. Low who, in that position since April 1967, led the agency’s efforts to recover from the Apollo 1 fire and originated the idea to send Apollo 8 on a lunar orbital mission. Under his tenure, NASA successfully completed five crewed Apollo missions including the first human Moon landing. MSC Director Robert R. Gilruth initially assigned Low to plan future programs until Nov. 13, when President Richard M. Nixon nominated him as NASA deputy administrator. The Senate confirmed Low’s nomination on Nov. 25, and NASA Administrator Thomas O. Paine swore him in on Dec. 3. Low filled the position vacant since March 20, 1969.

NASA’s Hidden Figures Honored with Congressional Gold Medals

4 Min Read NASA’s Hidden Figures Honored with Congressional Gold Medals Sen. Shelly Moore Capito (R-WV), delivers remarks during a Congressional Gold Medal ceremony recognizing NASA’s Hidden Figures, Wednesday, Sept. 18, 2024, in Emancipation Hall at the U.S. Capitol in Washington.

A simple turn of phrase was all it took for U.S. Sen. Shelley Moore Capito of Katherine Johnson’s home state of West Virginia to capture the feeling in Emancipation Hall at the U.S. Capitol in Washington.

“It’s been said that Katherine Johnson counted everything,” she said. “But today we’re here to celebrate the one thing even she couldn’t count, and that’s the impact that she and her colleagues have had on the lives of students, teachers, and explorers.”

That sense of admiration and awe toward the legacy and impact of NASA’s Hidden Figures was palpable Wednesday during a Congressional Gold Medal Ceremony to honor the women’s work and achievements during the space race.

The ceremony, hosted by House Speaker Mike Johnson, honored Johnson, Dorothy Vaughan, Mary Jackson, and Dr. Christine Darden of NASA’s Langley Research Center in Hampton, Virginia, along with all the other women who served at the agency and its precursor, the National Advisory Committee for Aeronautics, or the NACA, as computers, mathematicians, and engineers.

“The pioneers we honor today, these Hidden Figures — their courage and imagination brought us to the Moon. And their lessons, their legacy, will send us back to the Moon,” said NASA Administrator Bill Nelson.

Margot Lee Shetterly, whose 2016 nonfiction book “Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race,” brought awareness to the stories of NASA’s human computers, spoke at the event.NASA/Joel Kowsky

Author Margot Lee Shetterly detailed the stories of the women from NASA Langley in her 2016 nonfiction book “Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race.” Though the book focused on NASA Langley, where Shetterly’s father worked, it helped raise awareness of similar stories around NASA.

A film adaptation of the book starring Taraji Henson as Johnson, Octavia Spencer as Vaughan, and Janelle Monáe as Jackson came out later that year and further elevated the topic. NASA participated under a Space Act Agreement with 20th Century Fox in activities around the movie, to provide historical guidance and advice during the filmmaking process.

In her remarks, Shetterly noted that even as the Hidden Figures made such key contributions to NASA and the NACA before it, they remained active in their communities, leading Girl Scout troops and delivering meals to the hungry.

“They spent countless hours tutoring kids so that those kids, too, would see the power and the beauty of numbers they believed in, tending to the small D democracy that binds us to each other as neighbors and as American citizens,” she said.

The medal citations were as follows:

  • Congressional Gold Medal to Katherine Johnson, in recognition of her service to the United States as a mathematician
  • Congressional Gold Medal to Dr. Christine Darden, for her service to the United States as an aeronautical engineer
  • Congressional Gold Medals in commemoration of the lives of Dorothy Vaughan and Mary Jackson, in recognition of their service to the United States during the space race

Andrea Mosie, senior Apollo sample processor and lab manager who oversees the 842 pounds of Apollo lunar samples, accepted the medal awarded to all NASA’s Hidden Figures. She began her career at NASA’s Johnson Space Center in Houston in the 1970s.

Mosie thanked Congress for supporting NASA’s campaign to send the first woman and first person of color to the Moon as part of Artemis and the agency’s efforts to provide “opportunities for people, more representative of the way our country looks, to understand humanity’s place in the universe.”

Several NASA Langley officials attended the event to honor the legacies of the women who worked there.

“I am humbled by the significant contributions and lasting impact of these women to America’s aeronautics and space programs. Their brilliance and perseverance still echo not just through the halls of NASA Langley, but through the entire Agency,” said NASA Langley’s Acting Center Director Dawn Schaible. “They are an inspiration to me and countless others who have benefited from the paths they forged.”

Rep. Eddie Bernice Johnson of Texas, who passed away in 2023, introduced H.R. 1396 – Hidden Figures Congressional Gold Medal Act on Feb. 27, 2019. It was signed into law later that year.

In 2015, President Barack Obama presented Katherine Johnson with the Presidential Medal of Freedom, the nation’s highest civilian honor.

Plants Would Still Grow Well Under Alien Skies

Universe Today - Thu, 09/19/2024 - 4:45pm

Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto land, protected from the Sun’s intense ultraviolet radiation.

But Earth’s photosynthetic organisms evolved under the Sun’s specific illumination. How would plants do under other stars?

Our Sun is a G-type star, sometimes called a yellow dwarf. It seems like a normal star to us, but yellow dwarfs aren’t that common. Only about 7% to 8% of stars in the Milky Way are G-type stars. When it comes to understanding habitability on exoplanets, we need to understand the more plentiful types of stars.

Some scientists propose that K-dwarf stars are the most optimal host stars for habitable exoplanets. They’re between about 50% and 80% as massive as G-type stars, are more abundant and have stable luminosities for billions of years longer than Sun-like stars. The Sun will be stable on the main sequence for about 10 billion years, while K-type stars can be stable for up to 70 billion years. Despite this, much exoplanet habitability research focuses on M-dwarfs, or red dwarfs, which may actually be far more inhospitable to life because of flaring and tidal locking.

In a new study, a trio of researchers simulated the light output from a K-dwarf star and grew two photosynthetic organisms in those conditions to see how they responded. The research article is “Observation of significant photosynthesis in garden cress and cyanobacteria under simulated illumination from a K dwarf star.” It’s published in the International Journal of Astrobiology, and the lead author is Iva Vilovi?, a PhD student in the Astrobiology Research Group at the Technical University of Berlin.

Garden cress, whose Latin name is Lepidium sativum, is a common garden green used in salads, soups, and sandwiches. It’s an adaptable plant that grows rapidly. The cyanobacterium Chroococcidiopsis is an extremophile known for lying dormant for 13 million years and remaining viable. It can resist radiation, desiccation, and extreme temperatures and is of interest in astrobiology.

We expect photosynthesis to play a role in astrobiology. Starlight provides the energy for organisms to synthesize organic compounds. In order to understand photosynthesis in astrobiology, we need to understand how other stars could power photosynthesis. “Therefore, understanding any planet in the context of its stellar environment is an essential step in assessing its habitability,” the authors write.

Astronomers search for Earth-like planets around Sun-like stars because that’s the only life we know of. They also pay special attention to M-dwarfs because they’re so plentiful and are known to host many rocky exoplanets in their habitable zones. Scientists have demonstrated that photosynthetic organisms from Earth can grow under simulated M-dwarf light. But M-dwarf habitability faces a whole host of potential barriers.

In this work, the researchers focused on K-dwarfs. They lack the magnetic activity that appears to generate extremely powerful flaring on M-dwarfs, flaring so powerful that it could sterilize planets in their liquid-water habitable zone. The habitable zones around K-dwarfs are also far enough away that planets wouldn’t be tidally locked, another potential barrier to habitability that affects M-dwarfs. K-dwarfs also become habitable sooner in their lives than M-dwarfs due to their rapidly weakening FUV and X-ray fluxes.

“All things combined, K dwarfs can be considered the ‘Goldilocks stars’ in the search for potentially life-bearing planets,” the authors write.

The trio of researchers exposed watercress seedlings to three different light regimes: sunlight, K-dwarf light, and no light. Visually, the solar and K-dwarf samples were similar, though most of the time, the seeds sprouted a day or two earlier than under solar light. The K-dwarf sample also had marginally larger leaf surface area.

The researchers grew garden cress (Lepidium sativum) on a sand substrate with one hundred initial seedlings under Solar (effective temperature 5800 K), K dwarf (effective temperature 4300 K) and dark conditions. This image shows the visual results for selected days. Garden cress under K dwarf radiation sprouts sooner relative to Solar and dark conditions. Image Credit: Vilovi? et al. 2024.

After seven days, a side view of the samples showed that height and stem elongation were different. Under the K-dwarf lighting, the watercress grew taller.

The researchers also measured water content and dry mass. Under K-dwarf conditions, the watercress had slightly higher water content, while the dry content was lower compared to solar conditions.

The researchers also tested the photosynthetic efficiency and found no significant difference between the solar and K-dwarf samples.

The hardy extremophile Cyanobacterium Chroococcidiopsis sp. CCMEE 029 is at the other end of the spectrum from the quick-growing garden cress. It’s a survivor that can withstand long periods of dormancy and extreme growing conditions. The researchers also cultivated it under Solar, K-dwarf and dark conditions.

They measured the average integrated density (IntD) of the cyanobacterium, which is an indicator of culture growth. They found that the K-dwarf sample exhibited higher values than the solar sample, but the differences were not considered significant. Predictably, “Cyanobacteria under constant dark conditions failed to exhibit significantly measurable IntD,” the authors write in their paper.

This figure from the research article shows incremental ratios and integrated densities of the cyanobacterium on selected days under Solar, K dwarf and dark conditions. Though the integrated density was higher under K-dwarf conditions, the difference isn’t significant, according to the researchers. Image Credit: Vilovi? et al. 2024.

They point out that their study didn’t replicate natural conditions completely. Sunlight intensity changes throughout the day, but they didn’t include that in their study. “Sunlight intensity on Earth varies throughout the day, with peak intensities occurring during the central hours. This variation is crucial for plants to adapt and respond to changing light conditions, including the activation of non-photochemical quenching (NPQ) to mitigate the effects of excess light,” they write. NPQ helps plants cope with periods of excess light, meaning light above what it can photosynthesize, by dissipating it as heat.

“Understanding the effects of K-dwarf radiation on photosynthesis and growth is of foremost importance not only for the assessment of its viability for phototrophic organisms but also for the interpretation of atmospheric biosignatures outside of the Solar System,” the authors explain. Other research in this area has focused on M-dwarfs, and this trio of researchers say that to the best of their knowledge, theirs is the first to look at photosynthesis and K-dwarfs.

“These results can bring us closer to addressing which stellar environments could be the optimal candidates in the search for habitable worlds,” the authors write. “These findings not only highlight the coping mechanisms of photosynthetic organisms to modified radiation environments but also they imply the principal habitability of exoplanets orbiting K dwarf stars.”

The Polaris Dawn Crew is Back on Earth

Universe Today - Thu, 09/19/2024 - 4:21pm

On September 15th, 2024, the Polaris Dawn crew returned to Earth after spending five days in orbit. The mission was the first of three planned for the Polaris program, a private space project to advance human spaceflight capabilities and raise funds and awareness for charitable causes. The mission’s Dragon spacecraft safely splashed down off the coast of Florida at 3:36:54 a.m. EDT (12:36:54 p.m. PDT). Once their spacecraft was retrieved, the crew was flown to the Kennedy Space Center to see their families and undergo medical examinations before traveling to Houston to complete more of the mission’s studies.

The mission accomplished several objectives, including flying higher than any previous crewed mission since the Apollo Era – 1,408 km (875 mi) above the Earth’s surface, or three times the altitude of the International Space Station (ISS). The mission passed through the Van Allen Radiation Belt to learn more about the effects of space radiation on human physiology. For starters, the mission included the first-ever commercial spacewalk, performed by mission commander Jared Isaacman when the spacecraft was 700 km (435 mi) above Earth.

This feat also tested SpaceX’s new Extravehicular Activity Spacesuit (EVA), designed for long-duration spaceflight and operations on the lunar and Martian surface. Other experiments included Starlink’s laser-based communications system, which is essential for future missions to the Moon, Mars, and beyond. This consisted of the crew sending signals between optical links on the Dragon spacecraft and Starlink satellites. The crew also carried out 36 other science experiments, in collaboration with 31 global institutions, designed to advance human health and space exploration.

The mission also featured a special reading of Kisses from Space, written by Anna Menon (Polaris Dawn’s mission specialist and medical officer) and Keri Vasek. The event was live-streamed and showed Menon sharing her book with her family and many patients at St. Jude Children’s Research Hospital – one of the charitable organizations supported by the Polaris Program. The mission also had a “music moment,” where mission specialist Sarah Gillis played “Rey’s Theme” on the violin from The Force Awakens composed by John Williams.

The recording was back to Earth via Starlink, where it was accompanied by professional and youth musicians from around the world through a series of pre-recorded orchestra sessions. The combined footage was used to create the video “Harmony of Resilience” in support of St. Jude Children’s Research Hospital and El Sistema USA, a charity dedicated to providing access to music education for all children. Additional updates about the mission and crew post-return will continue to be available via Polaris’ official X account, Instagram, and their website

The second flight in the Polaris Program will see another crewed Dragon spacecraft launching to orbit and conducting additional experiments to advance human spaceflight, in-space communications, and scientific experiments. The launch date for this mission is currently TBD. The third mission (also TBD) will be the first crewed spaceflight using SpaceX’s Starship and Superheavy launch system.

Building a Worldwide Map of Light Pollution

Universe Today - Thu, 09/19/2024 - 3:58pm

As someone that has always lived in the UK countryside I am no stranger to the glory of a dark star-filled sky. Sadly 60% of the world’s population has already lost access to the night sky thanks to light pollution. Across Europe and the US that number climbs to nearer 80%. A team of researchers want to try and track the growth of light pollution and to that end have developed an inexpensive sensor made from “off-the-shelf” parts. Their hope is that people around the world will build and install these sensors to share their data enabling them to track the spread of light pollution. If you’ve got technical skills, this could be a fun project.

Astronomers the world over are all too familiar with the scourge of light pollution. It’s one of the main reasons observatories tend to be located in the middle of nowhere. Of course the night sky is illuminated by natural light from the stars and Moon but also zodiacal light and aurora can shed their own mystical light on our sky. Light pollution doesn’t refer to these natural wonders, instead it refers to the excessive or misdirected artificial light from human activity. 

Urban sprawl and accompanying light pollution is an issue for both astronomers and fireflies. This view shows the light dome from the city of Duluth, Minn. 20 miles north of town. It erases the dark skies. Credit: Bob King

Light pollution not only effects astronomers but it disrupts ecosystems, wildlife and even human health. It typically comes from streetlights, building lighting, advertising and even car headlights. It generally creates a nasty orange or white glow that hangs over towns and cities obscuring the beauty of the universe. It also interferes with with the behaviour of nocturnal animals, has a negative impact on human sleep cycles and can lead to health issues like insomnia or stress. There are suitable ways external lighting can be controlled and its impact minimised but we need to get people to actually want to make that change.

That’s the dream of the team behind the FreeDSM device and the Gaia4Sustaniability project. Their aim is to provide an easy to use piece of hardware and software which is reliable and will be able to measure night sky brightness caused by light pollution. The framework will be able to calculate the excess light pollution which is in excess of natural sky brightness to inform public, non-scientific stakeholders and the science community about the spread of light pollution.

Using hardware that is readily available the device is relatively cheap to build coming in at less than $65 USD (around £50 GBP.) It is based around the Osram TSL2591 sensor with two diodes.  One of them takes sky brightness measurements in the infrared and the other in the full visible spectrum. It then samples the brightness every minute while it also captures humidity and temperature. Looking at the relatively comprehensive instructions it looks like anyone with modest DIY skills will be able to build this. 

The device is an excellent step forward toward analysing the state of light pollution across the planet. It uses data from the Gaia satellite to greatly enhance the accuracy of the light pollution measurements. It does require legions of groups or individuals to build and install a device however. Hopefully it will appeal to the several thousands of fellow geeks out there   to pick up their screwdriver and soldering iron to make the dream of turning the tide on light pollution a reality.

If you want to have a go for yourself then you can learn more about the project here and find the instructions to build your own sensor here
