2 Min Read NASA Announces Winners of 2025 Human Lander Challenge
NASA’s Human Lander Challenge marked its second year on June 26, awarding $18,000 in prize money to three university teams for their solutions for long-duration cryogenic, or super chilled, liquid storage and transfer systems for spaceflight.
Building on the crewed Artemis II flight test, NASA’s Artemis III mission will send astronauts to explore the lunar South Pole region with a human landing system and advanced spacesuits, preparing humanity to ultimately go to Mars. In-space propulsion systems that use cryogenic liquids as propellants must stay extremely cold to remain in a liquid state and are critical to mission success. The Artemis mission architecture will need these systems to function for several weeks or even months.
Students and advisors with the 12 finalist teams for the 2025 Human Lander Challenge competed in Huntsville, Alabama, near the agency’s Marshall Space Flight Center between June 24-26. NASA/Charles Beason NASA announced Embry-Riddle Aeronautical University, Prescott as the overall winner and recipient of the $10,000 top prize award. Old Dominion University won second place and a $5,000 award, followed by Massachusetts Institute of Technology in third place and a $3,000 award.
Before the winners were announced, 12 finalist teams selected in April gave their presentations to a panel of NASA and industry judges as part of the final competition in Huntsville. As part of the 2025 Human Lander Challenge, university teams developed systems-level solutions that could be used within the next 3-5 years for Artemis.
NASA selected Embry-Riddle Aeronautical University, Prescott as the overall winner of NASA’s 2025 Human Lander Challenge Forum June 26. Lisa Watson-Morgan, manager of NASA’s Human Landing System Program, presented the awards at the ceremony. NASA/Charles Beason “Today’s Golden Age of Innovation and Exploration students are tomorrow’s mission designers, systems engineers, and explorers,” said Juan Valenzuela, main propulsion systems and cryogenic fluid management subsystems lead for NASA’s Human Landing System Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The Human Lander Challenge concepts at this year’s forum demonstrate the ingenuity, passion, and determination NASA and industry need to help solve long-duration cryogenic storage challenges to advance human exploration to deep space.”
The challenge is sponsored by the agency’s Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace.
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.

6 Min Read NASA’s Chandra Shares a New View of Our Galactic Neighbor
The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way.
The galaxy M31 has played an important role in many aspects of astrophysics, but particularly in the discovery of dark matter. In the 1960s, astronomer Vera Rubin and her colleagues studied M31 and determined that there was some unseen matter in the galaxy that was affecting how the galaxy and its spiral arms rotated. This unknown material was named “dark matter.” Its nature remains one of the biggest open questions in astrophysics today, one which NASA’s upcoming Nancy Grace Roman Space Telescope is designed to help answer.

This image includes X-rays from NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton (represented in red, green, and blue); ultraviolet data from NASA’s retired GALEX (blue); optical data from astrophotographers using ground based telescopes (Jakob Sahner and Tarun Kottary); infrared data from NASA’s retired Spitzer Space Telescope, the Infrared Astronomy Satellite, COBE, Planck, and Herschel (red, orange, and purple); and radio data from the Westerbork Synthesis Radio Telescope (red-orange).

Frattare, K. Arcand, J.Major Each type of light reveals new information about this close galactic relative to the Milky Way. For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as well as many other smaller compact and dense objects strewn across the galaxy. A recent paper about Chandra observations of M31 discusses the amount of X-rays produced by the supermassive black hole in the center of the galaxy over the last 15 years. One flare was observed in 2013, which appears to represent an amplification of the typical X-rays seen from the black hole.
These multi-wavelength datasets are also being released as a sonification, which includes the same wavelengths of data in the new composite. In the sonification, the layer from each telescope has been separated out and rotated so that they stack on top of each other horizontally, beginning with X-rays at the top and then moving through ultraviolet, optical, infrared, and radio at the bottom. As the scan moves from left to right in the sonification, each type of light is mapped to a different range of notes, from lower-energy radio waves up through the high energy of X-rays. Meanwhile, the brightness of each source controls volume, and the vertical location dictates the pitch.

Santaguida This new image of M31 is released in tribute to the groundbreaking legacy of Dr. Vera Rubin, whose observations transformed our understanding of the universe. Rubin’s meticulous measurements of Andromeda’s rotation curve provided some of the earliest and most convincing evidence that galaxies are embedded in massive halos of invisible material — what we now call dark matter. Her work challenged long-held assumptions and catalyzed a new era of research into the composition and dynamics of the cosmos. In recognition of her profound scientific contributions, the United States Mint has recently released a quarter in 2025 featuring Rubin as part of its American Women Quarters Program — making her the first astronomer honored in the series.

Visual Description
This release features several images and a sonification video examining the Andromeda galaxy, our closest spiral galaxy neighbor. This collection helps astronomers understand the evolution of the Milky Way, our own spiral galaxy, and provides a fascinating insight into astronomical data gathering and presentation.
Like all spiral galaxies viewed at this distance and angle, Andromeda appears relatively flat. Its spiraling arms circle around a bright core, creating a disk shape, like a large dinner plate. In most of the images in this collection, Andromeda’s flat surface is tilted to face our upper left.
This collection features data from some of the world’s most powerful telescopes, each capturing light in a different spectrum. In each single-spectrum image, Andromeda has a similar shape and orientation, but the colors and details are dramatically different.
In radio waves, the spiraling arms appear red and orange, like a burning, loosely coiled rope. The center appears black, with no core discernible. In infrared light, the outer arms are similarly fiery. Here, a white spiraling ring encircles a blue center with a small golden core. The optical image is hazy and grey, with spiraling arms like faded smoke rings. Here, the blackness of space is dotted with specks of light, and a small bright dot glows at the core of the galaxy. In ultraviolet light the spiraling arms are icy blue and white, with a hazy white ball at the core. No spiral arms are present in the X-ray image, making the bright golden core and nearby stars clear and easy to study.
In this release, the single-spectrum images are presented side by side for easy comparison. They are also combined into a composite image. In the composite, Andromeda’s spiraling arms are the color of red wine near the outer edges, and lavender near the center. The core is large and bright, surrounded by a cluster of bright blue and green specks. Other small flecks in a variety of colors dot the galaxy, and the blackness of space surrounding it.
This release also features a thirty second video, which sonifies the collected data. In the video, the single-spectrum images are stacked vertically, one atop the other. As the video plays, an activation line sweeps across the stacked images from left to right. Musical notes ring out when the line encounters light. The lower the wavelength energy, the lower the pitches of the notes. The brighter the source, the louder the volume.

NASA tested RS-25 engine No. 20001 on June 20, at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. Test teams fired the engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon.

The Artemis campaign will 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.
Four RS-25 engines, built by contractor L3Harris Technologies (formerly Aerojet Rocketdyne), help power each SLS launch, producing up to 2 million pounds of combined thrust. During the test, operators also fired engine No. 20001 up to the 111% power level, the same amount of thrust needed to launch an SLS rocket, carrying the Orion spacecraft, to orbit. The full-duration “hot fire” was the first test since NASA completed certification testing for new production RS-25 engines in 2024.
All RS-25 engines are tested and proven flightworthy at NASA Stennis. The test was conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.
