Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Marshall Space Flight Center invites the community to help celebrate the center’s 65th anniversary during a free public event noon to 5 p.m. CDT Saturday, July 19, at The Orion Amphitheater in Huntsville, Alabama.
NASA Marshall, along with its partners and collaborators, will fill the amphitheater with space exhibits, music, food vendors, and hands-on activities for all ages. The summer celebration will mark 65 years of innovation and exploration, not only for Marshall, but for Huntsville and other North Alabama communities.
“Our success has been enabled by the continuous support we receive from Huntsville and the North Alabama communities, and this is an opportunity to thank community members and share some of our exciting mission activities,” Joseph Pelfrey, director of NASA Marshall, said.
Some NASA astronauts from Expedition 72 who recently returned from missions aboard the ISS (International Space Station) will participate in the celebratory event. The Expedition 72 crew dedicated more than 1,000 combined hours to scientific research and technology demonstrations aboard the space station and crew members in attendance will share their experiences in space.

In the bottom row are Roscosmos cosmonaut and Flight Engineer Aleksandr Gorbunov and NASA astronaut and Flight Engineer Nick Hague. NASA/Bill Stafford and Robert Markowitz “Every day, our Marshall team works to advance human spaceflight and discovery, such as working with our astronauts on the space station.” Pelfrey said. “We are honored Expedition 72 crew members will join us to help commemorate our 65-year celebration.”
The anniversary event will also include remarks from Pelfrey, other special presentations, and fun for the whole family.

From Space to Soil: How NASA Sees Forests
NASA uses satellite lidar technology to study Earth’s forests, key carbon sinks. The GEDI mission maps forest height and biomass from the International Space Station, while ICESat-2 fills polar data gaps. Together, they enable a first-of-its-kind global biomass map, guiding smarter forest conservation and carbon tracking.

3 Min Read NASA Engineers Simulate Lunar Lighting for Artemis III Moon Landing
Better understanding the lunar lighting environment will help NASA prepare astronauts for the harsh environment Artemis III Moonwalkers will experience on their mission. NASA’s Artemis III mission will build on earlier test flights and add new capabilities with the human landing system and advanced spacesuits to send the first astronauts to explore the lunar South Pole and prepare humanity to go to Mars.
Using high-intensity lighting and low-fidelity mock-ups of a lunar lander, lunar surface, and lunar rocks, NASA engineers are simulating the Moon’s environment at the Flat Floor Facility to study and experience the extreme lighting condition. The facility is located at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
NASA engineers inside the Flat Floor Facility at Marshall Space Flight Center in Huntsville, Alabama, mimic lander inspection and assessment tasks future Artemis astronauts may do during Artemis III. Lights are positioned at a low angle to replicate the strong shadows that are cast across the lunar South Pole. NASA/Charles Beason “The goal is really to understand how shadows will affect lander visual inspection and assessment efforts throughout a future crewed mission,” said Emma Jaynes, test engineer at the facility. “Because the Flat Floor Facility is similar to an inverted air hockey table, NASA and our industry partners can rearrange large, heavy structures with ease – and inspect the shadows’ effects from multiple angles, helping to ensure mission success and astronaut safety for Artemis III.”
Data and analysis from testing at NASA are improving models Artemis astronauts will use in preparation for lander and surface operations on the Moon during Artemis III. The testing also is helping cross-agency teams evaluate various tools astronauts may use.
The 86-foot-long by 44-foot-wide facility at NASA is one of the largest, flattest, and most stable air-bearing floors in the world, allowing objects to move across the floor without friction on a cushion of air.
Test teams use large, 12-kilowatt and 6-kilowatt lights to replicate the low-angle, high contrast conditions of the lunar South Pole. Large swaths of fabric are placed on top of the epoxy floor to imitate the reflective properties of lunar regolith. All the mock-ups are placed on air bearings, allowing engineers to easily move and situate structures on the floor.
The Flat Floor Facility is an air-bearing floor, providing full-scale simulation capabilities for lunar surface systems by simulating zero gravity in two dimensions. Wearing low-fidelity materials, test engineers can understand how the extreme lighting of the Moon’s South Pole could affect surface operations during Artemis III. NASA/Charles Beason “The Sun is at a permanent low angle at the South Pole of the Moon, meaning astronauts will experience high contrasts between the lit and shadowed regions,” Jaynes said. “The color white can become blinding in direct sunlight, while the shadows behind a rock could stretch for feet and ones behind a lander could extend for miles.”
The laboratory is large enough for people to walk around and experience this phenomenon with the naked eye, adding insight to what NASA calls ‘human in-the-loop testing.
NASA is working with SpaceX to develop the company’s Starship Human Landing System to safely send Artemis astronauts to the Moon’s surface and back to lunar orbit for Artemis III.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

2 Min Read NASA Seeks Commercial Feedback on Space Communication Solutions
An illustration of a commercial space relay ecosystem. Credits: NASA / Morgan Johnson NASA is seeking information from U.S. and international companies about Earth proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging agency science missions.
“As part of NASA’s Communications Services Project, the agency is working with private industry to solve challenges for future exploration,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN Program. “Through this effort, NASA missions will have a greater ability to command spacecraft, resolve issues in flight, and bring home more data and scientific discoveries collected across the solar system.”
In November 2024, NASA announced the TDRS (Tracking and Data Relay Satellite) system, the agency’s network of satellites relaying communications from the International Space Station, ground controls on Earth, and spacecraft, will support only existing missions.
NASA, as one of many customers, will obtain commercial satellite services rather than owning and operating a replacement for the existing satellite system. As NASA transitions to commercial relay services, the agency will leverage commercial capabilities to ensure support for future missions and stimulate private investment into the Earth proximity region. Commercial service offerings could become available to NASA missions as early as 2028 and will continue to be demonstrated and validated through 2031.
NASA’s SCaN issued a Request for Information on May 30. Responses are due by 5 p.m. EDT on Friday, July 11.
NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

Video: 00:01:40 Proba-3 artificially created what is normally a rare natural phenomenon: a total solar eclipse.
In a world first, ESA’s Proba-3 satellites flew in perfect formation, blocking the Sun’s bright disc to reveal its fiery corona. This enigmatic outer layer burns millions of degrees hotter than the Sun’s surface and drives the solar storms that can disrupt life on Earth.
With its first artificial eclipse, Proba-3 has captured detailed images of this mysterious region, offering scientists new insights into our star’s behaviour.
