Building A Giant Catchers' Mitt On The Moon

Universe Today - Tue, 05/20/2025 - 4:44pm

Members of the space exploration community are always coming up with novel ideas to solve problems that they view as holding back humanity's expansion into the cosmos. One such problem that has become more noticeable of late, due to the failure of several powered lunar landers, is the difficulty of landing on the Moon. To open up the wealth of resources on our nearest neighbor, we will have to regularly deliver cargo to it as well as ship cargo off of it. A new idea from Lunar Cargo, a company based in Europe, has come up with a novel, patented way to deliver cargo to the Moon - the Momentum Absorption Catcher for Express Deliveries on Non-Atmospheric Somata, or M.A.C.E.D.O.N.A.S.

Terraforming Mars Could Be Within Reach

Universe Today - Tue, 05/20/2025 - 2:54pm

Mars has fascinated us for centuries. Since the invention of the telescope, science fiction writers have mused over its habitability. Its location in the Solar System's habitable zone suggests it could, in theory, support life—despite lacking a global magnetic field and surface water. In a new paper, researchers propose that terraforming Mars is now an achievable goal. They outline methods for warming the planet, releasing pioneer species to build an ecosystem, and improving its atmosphere.

NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars 20 years ago. In this image, the bluish glow in the sky above the Sun would be visible to us if we were there, but an artifact of the panoramic camera’s infrared imaging capabilities is that with this filter combination, the redness of the sky farther from the sunset is exaggerated compared to the daytime colors of the Martian sky.

A CubeSat Propulsion System to Visit Near Earth Objects

Universe Today - Tue, 05/20/2025 - 1:50pm

In recent years, humanity has visited several near-Earth asteroids (NEAs), including Ryugu (Hayabusa2) and Didymos (DART). However, we will need more frequent missions to start gathering more helpful information about this class of over 37,000 space rocks. CubeSats have off-the-shelf components and a relatively small size, making them a potentially good candidate for such an exploration program. But how would they reach these asteroid locations given their relatively limited payload and propulsion capacity? That is the focus of a new paper from Alessandro Quarta of the University of Pisa. He looks at potential trajectory planning for CubeSats given one of several configurations of ion drives. He shows how many NEAs can be accessed by simply entering a heliocentric orbit and awaiting the asteroid's arrival as part of its orbit.

NASA Sets Coverage for 32nd SpaceX Resupply Mission Departure

NASA News - Tue, 05/20/2025 - 1:42pm
The SpaceX Dragon cargo spacecraft, on NASA’s 30th Commercial Resupply Services mission, is pictured docked to the space-facing port on the International Space Station’s Harmony module on March 23, 2024.Credit: NASA

NASA and its international partners will soon receive scientific research samples and hardware after a SpaceX Dragon spacecraft departs the International Space Station on Thursday, May 22, for its return to Earth.

Live coverage of undocking and departure begins at 11:45 a.m. EDT on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.

The Dragon spacecraft will undock from the zenith, or space-facing, port of the station’s Harmony module at 12:05 p.m. and fire its thrusters to move a safe distance away from the station under command by SpaceX’s Mission Control in Hawthorne, California.

After re-entering Earth’s atmosphere, the spacecraft will splash down on Friday, May 23, off the coast of California. NASA will post updates on the agency’s space station blog. There is no livestream video of the splashdown.

Filled with nearly 6,700 pounds of supplies, science investigations, equipment, and food, the spacecraft arrived at the space station on April 22 after launching April 21 on a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida for the agency’s SpaceX 32nd commercial resupply services mission.

Some of the scientific hardware and samples Dragon will return to Earth include MISSE-20 (Multipurpose International Space Station Experiment), which exposed various materials to space, including radiation shielding and detection materials, solar sails and reflective coatings, ceramic composites for reentry spacecraft studies, and resins for potential use in heat shields. Samples were retrieved on the exterior of the station and can improve knowledge of how these materials respond to ultraviolet radiation, atomic oxygen, charged particles, thermal cycling, and other factors.

Additionally, Astrobee-REACCH (Responsive Engaging Arms for Captive Care and Handling) is returning to Earth after successfully demonstrating grasping and relocating capabilities on the space station. The REACCH demonstration used Astrobee robots to capture space objects of different geometries or surface materials using tentacle-like arms and adhesive pads. Testing a way to safely capture and relocate debris and other objects in orbit could help address end-of-life satellite servicing, orbit change maneuvers, and orbital debris removal. These capabilities maximize satellite lifespan and protect satellites and spacecraft in low Earth orbit that provide services to people on Earth.

Books from the Story Time from Space project also will return. Crew members aboard the space station read five science, technology, engineering, and mathematics-related children’s books in orbit and videotaped themselves completing science experiments. Video and data collected during the readings and demonstrations were downlinked to Earth and were posted in a video library with accompanying educational materials.

Hardware and data from a one-year technology demonstration called OPTICA (Onboard Programmable Technology for Image Compression and Analysis) also will return to Earth. The OPTICA technology was designed to advance transmission of real-time, ultra-high-resolution hyperspectral imagery from space to Earth, and it provided valuable insights for data compression and processing that could reduce the bandwidth required for communication, lowering the cost of acquiring data from space-based imaging systems without reducing the volume of data. This technology also could improve services, such as disaster response, that rely on Earth observations.

For more than 24 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and conducting critical research for the benefit of humanity and our home planet. Space station research supports the future of human spaceflight as NASA looks toward deep space missions to the Moon under the Artemis campaign and in preparation for future human missions to Mars, as well as expanding commercial opportunities in low Earth orbit and beyond.

Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from missions aboard the International Space Station.

NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Don Pettit will share highlights from their missions at 6 p.m. CDT Thursday, May 22, during a free, public event at NASA Johnson Space Center’s visitor center. The astronauts also will recognize key mission contributors during an awards ceremony after their presentation.

Williams and Wilmore launched aboard Boeing’s Starliner spacecraft and United Launch Alliance Atlas V rocket on June 5, 2024, from Space Launch Complex 41 as part of NASA’s Boeing Crew Flight Test. The duo arrived at the space station on June 6. In August, NASA announced the uncrewed return of Starliner to Earth and integrated Wilmore and Williams with the Expedition 71/72 crew and a return on Crew-9.

Hague launched Sept. 28, 2024, with Roscosmos cosmonaut Aleksandr Gorbunov aboard a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of NASA’s SpaceX Crew-9 mission. The next day, they docked to the forward-facing port of the station’s Harmony module.

Hague, Gorbunov, Wilmore, and Williams returned to Earth on March 18, 2025, splashing down safely off the coast of Tallahassee, Florida, in the Gulf of America.

Williams and Wilmore traveled 121,347,491 miles during their mission, spent 286 days in space, and completed 4,576 orbits around Earth. Hague and Gorbunov traveled 72,553,920 miles during their mission, spent 171 days in space, and completed 2,736 orbits around Earth. Hague has logged 374 days in space during two missions. It was the third spaceflight for both Williams and Wilmore. Williams has logged 608 total days in space, and Wilmore has logged 464 days.

Pettit launched aboard the Soyuz MS-26 spacecraft on Sept. 11, 2024, alongside Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The seven-month research mission as an Expedition 72 flight engineer was the fourth spaceflight of Pettit’s career, completing 3,520 orbits of the Earth and a journey of 93.3 million miles. He has logged a total of 590 days in orbit. Pettit and his crewmembers safely landed in Kazakhstan on April 19, 2025 (April 20, 2025, Kazakhstan time).

The Expedition 72 crew dedicated more than 1,000 combined hours to scientific research and technology demonstrations aboard the International Space Station. Their work included enhancing metal 3D printing capabilities in orbit, exploring the potential of stem cell technology for treating diseases, preparing the first wooden satellite for deployment, and collecting samples from the station’s exterior to examine whether microorganisms can survive in the harsh environment of space. They also conducted studies on plant growth and quality, investigated how fire behaves in microgravity, and advanced life support systems, all aimed at improving the health, safety, and sustainability of future space missions. Pettit also used his spare time and surroundings aboard station to conduct unique experiments and captivate the public with his photography. Expedition 72 captured a record one million photos during the mission, showcasing the unique research and views aboard the orbiting laboratory through astronauts’ eyes.

For more than 24 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and conducting critical research for the benefit of humanity and our home planet.
