Closing out February and coming into March has Gator fired up, and rightfully so!

Recent weeks and upcoming events remind us all how we are in a golden era of space exploration as NASA inspires the world through discovery.

For the first time in more than half a century, America returned to the Moon on Feb. 22 during the eighth day of a quarter-million-mile voyage under NASA’s Commercial Lunar Payload Services initiative with an Intuitive Machines lander named Odysseus. This Odysseus landing on the lunar South Pole makes way for future commercial deliveries to the Moon, along with future Artemis missions that will see humans return to the Moon, Mars, and beyond.

Speaking of Artemis, NASA Stennis is expected to carry out multiple RS-25 engine hot fires this month in the key test series for future Artemis flights of NASA’s SLS (Space Launch System) rocket.

Another example of NASA and NASA Stennis working with a commercial partner comes in the form of the first ever in-space autonomous systems mission involving NASA Stennis as a payload rider. The payload, part of project ASTRA (Autonomous Satellite Technology for Resilient Applications), is expected to launch soon on the Sidus Space LizzieSat TM small satellite.

In March, NASA will celebrate Women’s History Month. I invite you to read how one NASA Stennis employee’s interest in computer science brought her to the south Mississippi site, where she has become the first at NASA Stennis to reach a particular certification that showcases her dedication and level of skill to the job.

Can you feel it? The spring weather is here, and that shine outside is not only the Sun, but also this golden era of space exploration we all get to take part in and enjoy.

NASA Leaders Participate in Annual Stennis Day at the Capitol

Leaders from NASA’s Stennis Space Center and NASA Shared Services Center visit Jackson, Mississippi, in late February to share site updates with state leaders during the annual Stennis Day at the Capitol.

NASA Stennis Celebrates Milestone for Historic Autonomous Systems Mission

NASA’s Stennis Space Center and Sidus Space, Inc., marked another milestone February 15 for the Center’s first-ever in-flight autonomous systems software mission as a payload rider on the Sidus Space LizzieSatTM small satellite.

NASA Enters Second Half of Key RS-25 Engine Certification Series

NASA conducts a full-duration RS-25  hot fire Feb. 23 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, continuing a key test series for future Artemis flights of NASA’s SLS (Space Launch System) rocket. During the seventh test of the 12-test series, operators fired the certification engine for 550 seconds and up to a 113% power level. The hot fire followed installation of a second production engine nozzle that will provide additional performance data on the upgraded unit. The test series is the second, and final, series to certify restart production of the upgraded engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company. New engines will help power NASA’s SLS rocket on Artemis missions to the Moon and beyond, beginning with Artemis V. NASA and Aerojet Rocketdyne modified 16 former space shuttle engines for use on Artemis missions I through IV. NASA completed an initial 12-test certification series with the upgraded components in June 2023. Four RS-25 engines fire simultaneously to help launch each SLS rocket, producing up to 2 million pounds of combined thrust.

NASA Caps Off February with RS-25 Engine Certification Test

NASA conducted a full-duration RS-25  hot fire Feb. 29 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, continuing a key test series for future Artemis flights of NASA’s SLS (Space Launch System) rocket. The hot fire to certify new production RS-25 engines for SLS marked only the second ever Leap Day engine test. Fourty-four years ago on Feb. 29, 1980, before the first space shuttle launch, a test-fire occurred for RS-25 engine #0009. Both tests were conducted on the Fred Haise Test, previously known as the A-1 Test Stand at NASA Stennis. The Feb. 29, 2024, hot fire is the second test following installation of a second production engine nozzle that will provide additional performance data on the upgraded unit. It also marked the eighth in a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power NASA’s SLS rocket on Artemis missions to the Moon and beyond, beginning with Artemis V. The current series is the second and final series to certify restart production of the upgraded engines. NASA completed an initial 12-test certification series with the upgraded components in June 2023. Four RS-25 engines fire simultaneously to help launch each SLS rocket, producing up to 2 million pounds of combined thrust.

Preparations are underway for a new, small spacecraft technology demonstration that will test cost-efficient swarm capabilities – the ability for multiple spacecraft to communicate and perform coordinated actions. The PY4 mission’s four CubeSats are slated to launch Monday March 4, 2:05 p.m. PST to low Earth orbit aboard SpaceX’s Transporter-10 mission from Vandenberg Space Force Base in California.

Led by Carnegie Mellon University in Pittsburgh and funded by NASA’s Small Spacecraft Technology program, PY4 seeks to demonstrate spacecraft-to-spacecraft ranging, in-orbit navigation, and coordinated simultaneous multi-point radiation measurements at low size, weight, power, and cost. It uses a unique avionics platform called PyCubed that integrates power, computing, communications, attitude determination, and orbit control functionalities into a single board system. The PyCubed system is also open-source, programmable entirely in the Python programming language and uses affordable commercial off-the-shelf components.

Once in orbit at over 325 miles above Earth, the spacecraft will periodically measure their relative distances. These range measurements provide information about the spacecrafts’ positions relative to each other, and when combined with other sensor data, can be used to determine the configuration of the swarm. Advancing these capabilities could decrease the workload for operators on the ground while enabling multi-spacecraft missions at an accessible price point. The PY4 platform was previously used in demonstrations of the V-R3x technology, both in orbit and in a suborbital flight test on a commercial high-altitude balloon with NASA’s Flight Opportunities program. Those initial tests helped researchers evaluate PY4’s functionality ahead of this larger demonstration mission.

In addition to the PY4 demonstration, NASA is also testing critical swarming technologies via the agency’s ongoing Starling mission that launched in 2023. PY4 could dramatically reduce the cost of small spacecraft swarming capabilities and make demonstrating technologies like the autonomous navigation system tested via Starling more widely accessible by offering a flight-ready hardware and software platform.

The spacecraft were later transported to SpaceX for integration on the Falcon 9 rocket in preparation for launch.

PY4 is led by the Robotic Exploration Laboratory at Carnegie Mellon University with funding from the Small Spacecraft Technology program at NASA’s Ames. The Small Spacecraft Technology program expands the ability to execute unique missions through rapid development and demonstration of capabilities for small spacecraft applicable to exploration, science and the commercial space sector. Engineers at NASA Ames supporting the Small Spacecraft Technology program aided the assembly, testing, and integration of the four PY4 spacecraft as well as their delivery to Maverick Space Systems – the PY4 mission’s launch integrator.

In honor of Women’s History Month and those who paved the way for them, hundreds of female staff – from artists to administrative support, educators to engineers, and scientists to safety officers – gathered in front of the Katherine G. Johnson Computational Research Facility at NASA’s Langley Research Center in Hampton, Virginia, on Feb. 6, 2024.

“Their path to advancement might look less like a straight line and more like some of the pressure distributions and orbits they plotted, but they were determined to take a seat at the table.”  Margot Lee Shetterly, Hidden Figures

Shetterly wrote these words about Dorothy Vaughan, Mary Jackson, Christine Darden, and Katherine Johnson, the first Black women who worked as mathematicians at the Langley Memorial Aeronautical Laboratory, now NASA’s Langley Research Center­. These women were essential to the success of early spaceflight.
