NASA Shares Hidden Figures Congressional Gold Medal Remarks
NASA Administrator Bill Nelson released his remarks as prepared for Wednesday’s Hidden Figures Congressional Gold Medal ceremony in Washington. The awards recognized the women who contributed to the space race, including the NASA mathematicians who helped land the first astronauts on the Moon under the agency’s Apollo Program.
“Good afternoon.
“The remarkable things that NASA achieves…and that America achieves…build on the pioneers who came before us.
“People like the women of Mercury, Gemini, and Apollo.
“People like Mary Jackson. Dr. Christine Darden. Dorothy Vaughan. Katherine Johnson.
“Thanks to all the Members of Congress who made today possible. The late Congresswoman Eddie Bernice Johnson, who we miss, and who led the effort in 2019 alongside Senator Chris Coons to bring these medals to life. Thanks to the champions for the legislation, then-Senator Kamala Harris, Senators Lisa Murkowski and Shelley Moore Capito, and Congressman Frank Lucas.
“The women we honor today made it possible for Earthlings to lift beyond the bounds of Earth, and for generations of trailblazers to follow.
“We did not come this far only to come this far.
“We continue this legacy, as one member of the audience here with us does every single day – the remarkable Andrea Mosie.
“Andrea, who has worked at NASA for nearly 50 years, is the lead processor for the Apollo sample program. She oversees the Moon rocks and lunar samples NASA brought back from Apollo, 842 pounds of celestial science! These samples are national treasures. So is Andrea.
“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… and then…imagine – just imagine – when we leave our footprints on the red sands of Mars.
“Thanks to these people who are part of our NASA family, we will continue to sail on the cosmic sea to far off cosmic shores.”

Giant Leaps Start at Johnson for NASA’s SpaceX Crew-9 Commander Nick Hague
As the hub of human spaceflight, NASA’s Johnson Space Center in Houston holds a variety of unique responsibilities and privileges. Those include being the home of NASA’s astronaut corps.
One of those astronauts – Nick Hague – is now preparing to launch to the International Space Station along with Roscosmos cosmonaut Aleksandr Gorbunov on the ninth rotational mission under NASA’s Commercial Crew Program. This will be the third launch and second mission to the space station for Hague, who was selected as a NASA astronaut in 2013 and has spent 203 days in space.

Hague was born and raised in Kansas but has crisscrossed the country for college and career. He earned degrees from the United States Air Force Academy in Colorado and the Massachusetts Institute of Technology in Cambridge, and he attended the U.S. Air Force Test Pilot School at Edwards Air Force Base in California. Hague’s military career has taken him to New Mexico, Colorado, Virginia, and Washington, D.C., and included a five-month deployment to Iraq. Hague transferred from the Air Force to the U.S. Space Force in 2020 after serving as the Space Force’s director of test and evaluation at the Pentagon.
No stranger to new places, Hague vividly recalls making his first trip to Johnson when he was interviewing to join NASA’s astronaut corps. “I had no idea what to expect, and it was a bit overwhelming. I knew everyone was watching me and judging me,” he said. “Luckily, even though I wasn’t selected then, I got another chance a few years later. It’s a pretty magical place.”
Hague completed his astronaut training in July 2015 as part of NASA’s 21st astronaut class. He was the first astronaut from that group to be assigned to a mission, which launched in October 2018 but was aborted shortly after takeoff. His next spaceflight occurred in 2019, when he joined three of his classmates – NASA astronauts Jessica Meir, Christina Koch, and Andrew Morgan – aboard the International Space Station for Expeditions 59 and 60.

Hague has made many memories at Johnson, but one that stands out is his experience working onsite amid the 2013 government shutdown. “I’m active-duty military so I still came to work,” he explained. “I remember being onsite and the center being completely empty. Being able to ride around an empty campus on the free-range bikes – it was peaceful and surreal.” It was also a preview of what many Johnson employees experienced during the pandemic and how NASA maintains round-the-clock support for spaceflight operations regardless of extenuating circumstances.
Hague now looks ahead to another journey to low Earth orbit. NASA and SpaceX officials currently plan to launch the Crew-9 mission no earlier than Wednesday, Sept. 25. The crew will lift off from Launch Complex 40 from the Cape Canaveral Space Force Station in Florida aboard a SpaceX Falcon 9 rocket and Dragon spacecraft.

Hague and Gorbonov will become members of the Expedition 72 crew aboard the station. They will join NASA astronauts Butch Wilmore, Suni Williams, and Don Pettit, and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, and will spend about six months conducting scientific research in microgravity and completing a range of operational activities before returning home.

Hubble Examines a Busy Galactic Center
Hubble Examines a Busy Galactic Center
This NASA/ESA Hubble Space Telescope image features the spiral galaxy IC 4709 located around 240 million light-years away in the southern constellation Telescopium. Hubble beautifully captures its faint halo and swirling disk filled with stars and dust bands. The compact region at its core might be the most remarkable sight. It holds an active galactic nucleus (AGN).
If IC 4709’s core just held stars, it wouldn’t be nearly as bright. Instead, it hosts a gargantuan black hole, 65 million times more massive than our Sun. A disk of gas spirals around and eventually into this black hole, crashing together and heating up as it spins. It reaches such high temperatures that it emits vast quantities of electromagnetic radiation, from infrared to visible to ultraviolet light and X-rays. A lane of dark dust, just visible at the center of the galaxy in the image above, obscures the AGN in IC 4709. The dust lane blocks any visible light emission from the nucleus itself. Hubble’s spectacular resolution, however, gives astronomers a detailed view of the interaction between the quite small AGN and its host galaxy. This is essential to understanding supermassive black holes in galaxies much more distant than IC 4709, where resolving such fine details is not possible.
This image incorporates data from two Hubble surveys of nearby AGNs originally identified by NASA’s Swift telescope. There are plans for Swift to collect new data on these galaxies. Swift houses three multiwavelength telescopes, collecting data in visible, ultraviolet, X-ray, and gamma-ray light. Its X-ray component will allow SWIFT to directly see the X-rays from IC 4709’s AGN breaking through the obscuring dust. ESA’s Euclid telescope — currently surveying the dark universe in optical and infrared light — will also image IC 4709 and other local AGNs. Their data, along with Hubble’s, provides astronomers with complementary views across the electromagnetic spectrum. Such views are key to fully research and better understand black holes and their influence on their host galaxies.

SETI Scientists Scan TRAPPIST-1 for Technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn’t a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth, but the system is just 40 light-years away and has seven Earth-sized worlds. Three of them are in the potentially habitable zone of the star. They are clustered closely enough to experience tidal forces and thus be geologically active. If intelligent life arises easily in the cosmos, then there’s a good chance it exists in the TRAPPIST-1 system.
But finding evidence of intelligent life on a distant planet is difficult. Unless Mr. Mxyzptlk or the Great Gazoo want to talk about your car’s extended car warranty, any signal we detect will likely be subtle, similar to the stray radio signals we emit from Earth. So the challenge is to distinguish actual signals from aliens, known as technosignatures, from the naturally occuring emissions of stars and planets. Recently a team used the Allen Telescope Array to capture 28 hours of TRAPPIST-1 signals in an effort to find the elusive aliens.
The study began with a few assumptions. The biggest one was to presume that if TRAPPIST-1 has an intelligent civilization it is likely spread across more than one world. Given how compact the system is, that isn’t too outlandish. Getting from one world to another wouldn’t be much more difficult than it is for us to get to the Moon. With that assumption, the team then assumed that the worlds would transmit radio messages between each other. Since the signals would need to transverse interplanetary distances, they would be the strongest and most clear technosignatures in the system. So the team focused on signals during a planet-planet occultation (PPO). That is when two planets line up from our vantage point. During a PPO any signal sent from the far planet to the closer planet would spill over and eventually reach us.

Signals that were stronger than the expected range for natural signals. Then using computer models of the system they determined 7 possible PPO events and further narrowed things down to about 2,200 potential signals occurring during a PPO window. From there they went on to determine whether any of those signals were statistically unusual enough to suggest an intelligent origin. The answer to that was sadly no.
Alas, if there are aliens in the TRAPPIST-1 system, we haven’t found them yet. But the result shouldn’t minimize this study. It is the longest continuous survey of the system to date, which is pretty cool. And it’s kind of amazing that we’ve reached the point where we’re able to do this study. We are actively searching known exoplanets in detail.
