Research Payloads to Support Long-Duration Spaceflight and Improve Osteoarthritis and Cancer Treatment Return From Space Station
NASA's latest SpaceX resupply mission to the space station returns with ISS National Lab-sponsored projects advancing biomedical R&D, technology development, and physical sciences
KENNEDY SPACE CENTER, Fla., May 27, 2025 /PRNewswire/ — ELVIS is back. Samples from the Extant Life Volumetric Imaging System (ELVIS)—a new holographic microscope—have returned from the International Space Station (ISS). The samples splashed down off the coast of California alongside more than two dozen other investigations sponsored by the ISS National Laboratory®. Experiments returning on SpaceX's 32nd commercial resupply services mission for NASA include a project to manufacture nanomaterials in space to treat osteoarthritis and cancer on Earth and several investigations funded by the U.S. National Science Foundation (NSF).
These are a few highlights of the investigations that returned to Earth for further study to benefit humanity:
Using innovative holographic technology, ELVIS delivers detailed 3D views of cellular life, allowing scientists to study the adaptability and resilience of life under extreme conditions. Findings could reveal how life might persist on distant moons and planets, potentially enhancing the search for life beyond Earth. Portland State University, in collaboration with NASA's Jet Propulsion Laboratory in Southern California and Teledyne Brown Engineering, Inc., tested the advanced microscope system onboard the orbiting laboratory. A collection of samples examined on the space station returned for further analysis so the team can determine ELVIS' next steps in space.
Researchers from the University of Connecticut and Eascra Biotech, with support from Axiom Space, built on previous research to improve the production of innovative nanomaterials in space. Janus base nanomaterials (JBNs) are composed of synthetic molecules that self-assemble into structures resembling human DNA. The injectable nanomaterials could help regenerate cartilage in the joints of osteoarthritis patients and could be used to carry cancer drugs into hard-to-penetrate solid tumors. The team's groundbreaking research is featured in the most recent issue of Upward, official magazine of the ISS National Lab.
A project that is part of a series of investigations developed by the U.S. Air Force and the U.S. Air Force Academy, in partnership with Rhodium Scientific, examined how genetically modified tomato plants grow in the space environment. The team aimed to better understand how genetic modifications and gene expression changes influence root and shoot development. The researchers will compare results from this experiment with those from investigations on the Polaris Dawn and NASA's SpaceX Crew-9 missions, which featured the same Rhodium plant growth hardware. Findings could provide insights into the production of crops on long-duration space missions or in high-radiation environments.
An experiment from Sophie's BioNutrients, supported by BioServe Space Technologies, aims to develop plant-based, protein-rich alternatives to meat and seafood using microalgae. The investigation examined how microgravity affects protein yields in microalgae that require nutrition from organic compounds to grow. Results could provide insights into the fundamental mechanisms of microalgae cell growth, metabolism, and protein production. In addition to serving as a food source on long-duration spaceflight missions, microalgae could also be used in life support systems and to provide oils for fuel production.
Four investigations funded by NSF seek to advance fundamental science with valuable applications, continuing a strong, multiyear collaboration between NSF and the ISS National Lab. One of these projects, from Lehigh University, could enable the next generation of portable microfluidic devices that use bioseparation for virus detection. This process, which separates particles from fluids, relies on thermophoresis—the tendency of particles suspended in a solution to move from hot to cold regions along a temperature gradient. Bioseparation can be used in medical lab tests to detect the presence of a virus by separating virus particles from bodily fluids in samples.

Is China's Tiandu-1 first to enter resonant Earth-moon orbit? US raises doubts
China's Tiandu-1 satellite has entered a critical fuel-efficient orbit that synchronises with the motion of the Earth and moon, but claims that it is the first spacecraft to achieve the feat have been challenged by US and Canadian experts. The 3:1 resonant orbit – in which Tiandu-1 completes three loops of the Earth for every circuit made by the moon – is seen as a breakthrough for lunar infrastructure, including a BeiDou-like guidance system that will be needed for interplanetary exploration. Developer Deep Space Exploration Laboratory said that 'the Tiandu-1 navigation test satellite successfully carried out a key manoeuvre at perigee [the point in orbit when it is closest to Earth] on May 22 and precisely transitioned into a 3:1 Earth-moon resonant orbit'. 'This made Tiandu-1 the first spacecraft to enter a round-trip 3:1 Earth-moon resonant trajectory,' according to a statement on the website of the laboratory based in Hefei, Anhui province in central China. 'Its flight data will provide support for advancing technologies such as orbit maintenance, control, and autonomous navigation in complex gravitational environments.' Experts in the US and Canada immediately challenged the claim, pointing to Nasa's 15-year-old Interstellar Boundary Explorer (IBEX) probe that entered a near-identical orbit in 2011, where it continues to operate. Jonathan McDowell, a Harvard astronomer and space historian, and Canada-based amateur stargazer Scott Tilley both said it was debatable whether Tiandu-1 could lay claim to the title, with the IBEX craft's achievement of near 3:1 resonance. 'Yes, indeed Tiandu-1 has entered a 3:1 resonance orbit. Whether it's the first is launched in 2008 uses a similar orbit,' Tilley said. According to McDowell, the advantage of resonant orbits is that they allow a spacecraft to operate far from Earth while avoiding the unpredictable, chaotic motion caused by frequent lunar fly-bys. 'The resonance provides stability,' he said. In a 3:1 resonance, the 61kg (135lb) Tiandu-1 – which launched alongside the Queqiao-2 lunar relay satellite last year – completes each petal of its three-lobed orbit around the Earth roughly every nine days – the same amount of time it takes the moon to complete one. In April, state news agency Xinhua reported that China's DRO-B satellite had departed lunar orbit, after helping to establish the 'world's first three-satellite constellation in cislunar space', and entered an Earth-moon resonant orbit. DRO-B, a 277kg Chinese satellite that was salvaged after being stranded in the wrong orbit due to a launch mishap last year, is currently in a 3:2 Earth-moon resonant orbit, according to Tilley, who is best known for helping Nasa to find its long-lost IMAGE satellite in 2018. The Canadian amateur astronomer, who tracks satellites in his spare time, said he noticed that DRO-B had vanished from its known lunar orbit more than a month ago and began searching for it. Using graphics and research papers, Tilley modelled a 3:2 resonance orbit – one that tours the gravitational balance points between Earth and the moon known as L3, L4, and L5. After an exhaustive search, he spotted DRO-B in such an orbit. DRO-B completes three circles around Earth in the time it takes the moon to complete two. The satellite traces a broad, triangular loop with lobes near the L3, L4, and L5 points, which it swings past roughly every 18 days. 'DRO-B is not transmitting all the time like it used to, and it's likely [to be] having minor power issues as its solar panel supports were damaged during the launch mishap,' Tilley said. He added that DRO-B's orbit was especially notable because this specific class of 3:2 resonance orbit had never been used before. 'Japan's Hiten lunar probe did visit some of these points, but didn't use a 3:2 resonance orbit.' According to Tilley, China's use of these orbits seemed to be all about testing navigation-related technologies. 'Having a system that covers the entire Earth-moon system for orbital determination and positioning would be very helpful,' he said. - SOUTH CHINA MORNING POST

Trump's threat to cancel Musk's contracts exposes risks of US reliance on SpaceX
WASHINGTON, June 7 — SpaceX's rockets ferry US astronauts to the International Space Station. Its Starlink satellite constellation blankets the globe with broadband, and the company is embedded in some of the Pentagon's most sensitive projects, including tracking hypersonic missiles. So when President Donald Trump threatened on Thursday to cancel Elon Musk's federal contracts, space watchers snapped to attention. Musk, the world's richest person, shot back that he would mothball Dragon—the capsule Nasa relies on for crew flights—before retracting the threat a few hours later. For now, experts say mutual dependence should keep a full-blown rupture at bay, but the episode exposes just how disruptive any break could be. Founded in 2002, SpaceX leapfrogged legacy contractors to become the world's dominant launch provider. Driven by Musk's ambition to make humanity multiplanetary, it is now Nasa's sole means of sending astronauts to the ISS—a symbol of post-Cold War cooperation and a testbed for deeper space missions. Space monopoly? The company has completed 10 regular crew rotations to the orbiting lab and is contracted for four more, under a deal worth nearly US$5 billion. That's just part of a broader portfolio that includes US$4 billion from Nasa for developing Starship, the next-generation megarocket; nearly US$6 billion from the Space Force for launch services; and a reported US$1.8 billion for Starshield, a classified spy satellite network. Were Dragon grounded, the United States would again be forced to rely on Russian Soyuz rockets for ISS access — as it did between 2011 and 2020, following the Space Shuttle's retirement and before Crew Dragon entered service. 'Under the current geopolitical climate, that would not be optimal,' space analyst Laura Forczyk told AFP. Nasa had hoped Boeing's Starliner would provide redundancy, but persistent delays—and a failed crewed test last year—have kept it grounded. Even Northrop Grumman's cargo missions now rely on SpaceX's Falcon 9, the workhorse of its rocket fleet. The situation also casts a shadow over Nasa's Artemis programme. A lunar lander variant of Starship is slated for Artemis III and IV, the next US crewed Moon missions. If Starship were sidelined, rival Blue Origin could benefit—but the timeline would almost certainly slip, giving China, which aims to land humans by 2030, a chance to get there first, Forczyk warned. 'There are very few launch vehicles as capable as Falcon 9 — it isn't feasible to walk away as easily as President Trump might assume,' she said. Nasa meanwhile appeared eager to show that it had options. 'Nasa is assessing the earliest potential for a Starliner flight to the International Space Station in early 2026, pending system certification and resolution of Starliner's technical issues,' the agency said in a statement Friday to AFP. Still, the feud could sour Trump on space altogether, Forczyk cautioned, complicating Nasa's long-term plans. SpaceX isn't entirely dependent on the US government. Starlink subscriptions and commercial launches account for a significant share of its revenue, and the company also flies private missions. The next, with partner Axiom Space, will carry astronauts from India, Poland, and Hungary, funded by their respective governments. Private power, public risk But losing US government contracts would still be a major blow. 'It's such a doomsday scenario for both parties that it's hard to envision how US space efforts would fill the gap,' Clayton Swope, deputy director of the Aerospace Security Project at the Center for Strategic and International Studies, told AFP. 'Both sides have every reason to bridge the disagreement and get back to business.' Signs of a rift emerged last weekend, when the White House abruptly withdrew its nomination of e-payments billionaire Jared Isaacman — a close Musk ally who has twice flown to space with SpaceX — as Nasa administrator. On a recent podcast, Isaacman said he believed he was dropped because 'some people had some axes to grind, and I was a good, visible target.' The broader episode could also reignite debate over Washington's reliance on commercial partners, particularly when one company holds such a dominant position. Swope noted that while the US government has long favored buying services from industry, military leaders tend to prefer owning the systems they depend on. 'This is just another data point that might bolster the case for why it can be risky,' he said. 'I think that seed has been planted in a lot of people's minds — that it might not be worth the trust.' — AFP
