      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Daily images of ice cover in the Arctic Ocean (left) and around Antarctica reveal sea ice formation and melting at the poles over the course of two years (Sept 14, 2023 to Sept. 13, 2025).Trent Schindler/NASA’s Scientific Visualization Studio With the end of summer approaching in the Northern Hemisphere, the extent of sea ice in the Arctic shrank to its annual minimum on Sept. 10, according to NASA and the National Snow and Ice Data Center. The total sea ice coverage was tied with 2008 for the 10th-lowest on record at 1.78 million square miles (4.60 million square kilometers). In the Southern Hemisphere, where winter is ending, Antarctic ice is still accumulating but remains relatively low compared to ice levels recorded before 2016.
      The areas of ice covering the oceans at the poles fluctuate through the seasons. Ice accumulates as seawater freezes during colder months and melts away during the warmer months. But the ice never quite disappears entirely at the poles. In the Arctic Ocean, the area the ice covers typically reaches its yearly minimum in September. Since scientists at NASA and the National Oceanic and Atmospheric Administration (NOAA) began tracking sea ice at the poles in 1978, sea ice extent has generally been declining as global temperatures have risen. 
      “While this year’s Arctic sea ice area did not set a record low, it’s consistent with the downward trend,” said Nathan Kurtz, chief of the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
      Arctic ice reached its lowest recorded extent in 2012. Ice scientist Walt Meier of the National Snow and Ice Data Center at the University of Colorado, Boulder, attributes that record low to a combination of a warming atmosphere and unusual weather patterns. This year, the annual decline in ice initially resembled the changes in 2012. Although the melting tapered off in early August, it wasn’t enough to change the year-over-year downward trend. “For the past 19 years, the minimum ice coverage in the Arctic Ocean has fallen below the levels prior to 2007,” Meier said. “That continues in 2025.” 
      Antarctic sea ice nearing annual maximum
      As ice in the Arctic reaches its annual minimum, sea ice around the Antarctic is approaching its annual maximum. Until recently, ice in the ocean around the Southern pole has been more resilient than sea ice in the North, with maximum coverage increasing slightly in the years before 2015. “This year looks lower than average,” Kurtz said. “But the Antarctic system as a whole is more complicated,” which makes predicting and understanding sea ice trends in the Antarctic more difficult. 
      It’s not yet clear whether lower ice coverage in the Antarctic will persist, Meier said. “For now, we’re keeping an eye on it” to see if the lower sea ice levels around the South Pole are here to stay or only part of a passing phase. 
      A history of tracking global ice 
      For nearly five decades, NASA and NOAA have relied on a variety of satellites to build a continuous sea ice record, beginning with the NASA Nimbus-7 satellite (1978–1987) and continuing with the Special Sensor Microwave/Imager and the Special Sensor Microwave Imager Sounder on Defense Meteorological Satellite Program satellites that began in 1987. The Advanced Microwave Scanning Radiometer–for EOS on NASA’s Aqua satellite also contributed data from 2002 to 2011. Scientists have extended data collection with the 2012 launch of the Advanced Microwave Scanning Radiometer 2 aboard a JAXA (Japan Aerospace Exploration Agency) satellite.
      With the launch of ICESat-2 in 2018, NASA has added the continuous observation of ice thickness to its recording. The ICESat-2 satellite measures ice height by recording the time it takes for laser light from the satellite to reflect from the surface and travel back to detectors on board.
      “We’ve hit 47 years of continuous monitoring of the global sea ice extent from satellites,” said Angela Bliss, assistant chief of NASA’s Cryospheric Sciences Laboratory. “This data record is one of the longest, most consistent satellite data records in existence, where every single day we have a look at the sea ice in the Arctic and the Antarctic.”

      This artist’s concept shows NASA’s Neil Gehrels Swift Observatory orbiting above Earth.Credit: NASA’s Goddard Space Flight Center/Chris Smith (KBRwyle) To drive the development of key space-based capabilities for the United States, NASA is exploring an opportunity to demonstrate technology to raise a spacecraft’s orbit to a higher altitude. Two American companies – Cambrian Works of Reston, Virginia, and Katalyst Space Technologies of Flagstaff, Arizona – will develop concept design studies for a possible orbit boost for the agency’s Neil Gehrels Swift Observatory.
      Since its launch in 2004, NASA’s Swift mission has led the agency’s fleet of space telescopes in investigating changes in the high-energy universe. The spacecraft’s low Earth orbit has been decaying gradually, which happens to most satellites over time. Because of recent increases in the Sun’s activity, however, Swift is experiencing additional atmospheric drag, speeding up its orbital decay. This lowering orbit presents an opportunity for NASA to advance a U.S. industry capability, while potentially extending the science lifetime of the Swift mission. The concept studies will help determine whether extending Swift’s critical scientific capabilities would be more cost-effective than replacing those capabilities with a new observatory.
      “NASA Science is committed to leveraging commercial technologies to find innovative, cost-effective ways to open new capabilities for the future of the American space sector,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “To maintain Swift’s role in our portfolio, NASA Science is uniquely positioned to conduct a rare in-space technology demonstration to raise the satellite’s orbit and solidify American leadership in spacecraft servicing.”
      The concept studies are being developed under Phase III awards through NASA’s Small Business Innovation Research (SBIR) Program, managed by the agency’s Space Technology Mission Directorate, to American small businesses from a pool of existing participants. This approach allows NASA to rapidly explore affordable possibilities to boost Swift on a shorter development timeline than would otherwise be possible, given the rapid rate at which Swift’s orbit is decaying.
      At this time NASA does not have plans for an orbit boost mission and could still allow the spacecraft to reenter Earth’s atmosphere, as many satellites do at the end of their lifetimes. NASA is studying a potential Swift boost to support innovation in the American space industry, while gaining a better understanding of the available options, the technical feasibility, and the risks involved.
      NASA will also work with Starfish Space of Seattle, Washington, to analyze the potential of performing a Swift boost using an asset under development on an existing Phase III SBIR award. Starfish is currently developing the Small Spacecraft Propulsion and Inspection Capability (SSPICY) demonstration for NASA, with the primary objective of inspecting multiple U.S.-owned defunct satellites in low Earth orbit.
      “Our SBIR portfolio exists for circumstances like this – where investments in America’s space industry provide NASA and our partners an opportunity to develop mutually beneficial capabilities,” said Clayton Turner, associate administrator, Space Technology Mission Directorate, NASA Headquarters. “Whether we choose to implement the technologies in this circumstance, understanding how to boost a spacecraft’s orbit could prove valuable for future applications.”
      Swift was designed to observe gamma-ray bursts, the universe’s most powerful explosions, and provide information for other NASA and partner telescopes to follow up on these events. Its fast and flexible observations have been instrumental in advancing how scientists study transient events to understand how the universe works. For more than two decades, Swift has led NASA’s missions in providing new insights on these events, together broadening our understanding of everything from exploding stars, stellar flares, and eruptions in active galaxies, to comets and asteroids in our own solar system and high-energy lightning events on Earth.
      As neutron stars collide, some of the debris blasts away in particle jets moving at nearly the speed of light, producing a brief burst of gamma rays.NASA’s Goddard Space Flight Center/CI Lab “Over its extremely productive lifetime, Swift has been a key player in NASA’s network of space telescopes – directing our fleet to ensure we keep a watchful eye on changes in the universe, both far off and close to home,” said Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters. “Now, this long-lived science mission is presenting us with a new opportunity: partnering with U.S. industry to rapidly explore efficient, state-of-the-art solutions that could extend Swift’s transformative work and advance private spacecraft servicing.”
      Cambrian and Katalyst have each been awarded $150,000 under Phase III SBIR contracts for concept design studies. The NASA SBIR program is part of America’s Seed Fund, the nation’s largest source of early-stage, non-dilutive funding for innovative technologies. Through this program, entrepreneurs, startups, and small businesses with less than 500 employees can receive funding and non-monetary support to build, mature, and commercialize their technologies, advancing NASA missions and helping solve important problems facing our country.
      NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Swift mission in collaboration with Penn State, the Los Alamos National Laboratory in New Mexico, and Northrop Grumman Space Systems in Dulles, Virginia. Other partners include the UK Space Agency, University of Leicester and Mullard Space Science Laboratory in the United Kingdom, Brera Observatory in Italy, and the Italian Space Agency.
