NASA will announce the winners of the final phase of its Break the Ice Lunar Challenge on Wednesday, June 12 at Alabama A&M University’s (AAMU) Agribition Center in Huntsville, Alabama. The challenge aims to develop new technologies that could support a sustained human presence on the Moon by the end of the decade.

Media and the public are invited to watch the six finalists test their robots in live competitions. Opening remarks from NASA’s Marshall Space Flight Center leadership in Huntsville will begin at 8 a.m. CDT on Tuesday, June 11. Teams will compete from 8:30 a.m. to 4 p.m. each day during the two-day event, with the winner announcement at 5 p.m. in a ceremony on June 12 at the Agribition Center.

Media interested in covering the event should confirm their attendance with Jonathan Deal by 3 p.m. Monday, June 10, at jonathan.e.deal@nasa.gov.

Each team will focus on mastering two components during the two-day event: excavation and transportation. Six identically sized concrete slabs, measuring about 300 cubic feet, will be placed inside the arena for the finalists’ robots to dig. The slabs will have qualities like the icy regolith found in permanently shadowed craters at the Moon’s South Pole. A gravity-offloading crane system will apply the counterweights on the excavating robots to simulate the one-sixth gravity experienced on the Moon.

Each team will have one hour to dig as much material as possible or until they reach the payload capacity of their excavation robot. Up to three top-performing teams can test their solution inside one of NASA Marshall’s thermal vacuum chambers, which can simulate the temperature and vacuum conditions at the lunar South Pole.

Outside the Agribition Center, challenge teams will take turns on a custom-built track outfitted with slopes, boulders, pebbles, rocks, and gravel to simulate the lunar surface. This volatile surface will stretch approximately 300 meters and include several twists and turns for more intermediate handling. Each team will get one hour on the track to deliver a payload and return to the starting point. Times, distances, and pitfalls will be recorded independently.

After this event, the first-place winner will receive $1 million, and the second-place winner will receive $500,000.

The awards ceremony will be livestreamed on Marshall YouTube and NASA Prize Facebook.

Since 2020, competitors have worked to design, build, and test icy regolith excavation and transportation technologies for near-term lunar missions that address key operational elements and environmental constraints. The six finalists who succeeded in Phase 2: Level 2 of the challenge were announced in December 2023.

On Earth, the mission architectures developed in this challenge aim to help guide machine design and operation concepts for future mining and excavation operations and equipment for decades.

Located a few miles east of the AAMU campus, the Agribition (“agriculture” plus “exhibition”) Center is managed by the Alabama Cooperative Extension System with support from AAMU and its College of Agricultural, Life, and Natural Sciences.

The Break the Ice Lunar Challenge is a NASA Centennial Challenge led by the agency’s Marshall Space Flight Center, supported by NASA’s Kennedy Space Center in Florida. Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program led by NASA’s Space Technology Mission Directorate and managed at NASA Marshall. Ensemble Consultancy supports the management of competitors for this challenge.

SPoRT Undertakes New Collaboration with the United Nations (U.N.) Satellite Centre

SPoRT Undertakes New Collaboration with the United Nations (U.N.) Satellite Centre

Patrick Duran and Anita LeRoy (ST11) met with Samir Belabbes from the United Nations Institute for Training and Research to investigate ways for SPoRT to provide NASA remote sensing products to the UN Satellite Centre. The new collaboration springs from a presentation given by Belabbes at last year’s Joint Applications Workshop of NASA’s CYGNSS and TROPICS missions, which was organized by Duran and Jason Dunion from the University of Miami. The UN Satellite Centre maintains a 24/7 operational forecasting and disaster response center that serves UN member states. The Centre has a need for remote sensing datasets that enhance their ability to anticipate and respond to disasters, and data from new NASA missions such as TROPICS could be particularly beneficial for monitoring high-impact events. A key takeaway from the discussion is that the UN and its member states will be much better able to use NASA data if it is provided in GeoTIFF format. SPoRT will investigate ways to provide data products from current and upcoming NASA missions in this format for dissemination to UN member states and use at the UN operational forecasting and response centers.

Hubble Examines a Barred Spiral’s Light

A barred spiral galaxy seen face-on. Its many arms and distinct, glowing, bar-shaped core are easily visible. The galaxy’s arms hold bluish patches of older stars, pink patches where new stars are forming, and dark threads of dust. A few bright stars with cross-shaped diffraction spikes lie between us and the galaxy and are visible in the foreground.

This NASA/ESA Hubble Space Telescope image features the barred spiral galaxy NGC 3059, which lies about 57 million light-years from Earth. Hubble’s Wide Field Camera 3 collected the data in May 2024 as part of an observing program that studied a number of galaxies. All of the observations used the same range of filters: partially transparent materials that allow only very specific wavelengths of light to pass through.

Astronomers use filters extensively in their observations. These filters may allow either extremely narrow or somewhat broader ranges of light through to the telescope’s instruments. Narrow-band filters are invaluable from a scientific perspective because they filter specific wavelengths of light that are associated with specific physical and chemical processes. For example, under certain conditions, hydrogen atoms emit red light with a wavelength value of 656.46 nanometers called H-alpha emission, or the ‘H-alpha line’. It is very useful to astronomers because its presence indicates certain physical processes and conditions and is often a tell-tale sign of newly forming stars.

The data in this image used a narrow-band filter that allowed H-alpha emission through to the telescope’s detectors. The particular filter, called F657N (F for filter, N for narrow, and 657 for the wavelength in nanometers) or the H-alpha filter, lets through light very close to the 656.46 nanometer H-alpha line’s wavelength. It reveals pinkish star-forming regions in the galaxy.

Data from five other wide-band filters also contributed to this image. As their name implies, wide-band filters allow a wider range of wavelengths through to Hubble’s instruments. They isolate sections of the electromagnetic spectrum allowing astronomers to explore different aspects of the object Hubble is looking at.

In the case of this image, wide-band filters revealed the bluish patches that hold older stars. In addition, information from multiple filters provides image processors with the data to make beautiful and informative images such as this one.
