NASA abandons the Swift rescue, a solar eruption found with 17 spacecraft and microbes at the lunar pole
Katalyst Space's LINK spacecraft abandoned its attempt to boost Swift following attitude problems. Separately, 17 spacecraft exposed a solar eruption Earth models missed, and a simulation showed human-related microbes could survive shadowed ground at the lunar south pole.

The Swift rescue attempt ends over problems on the LINK spacecraft
Katalyst Space's LINK spacecraft ran into attitude control problems during commissioning after its 3 July 2026 launch, ending its mission to capture and boost the Neil Gehrels Swift Observatory. LINK will now demonstrate only rendezvous and proximity operations, leaving the telescope alone after 21 years of science operations and orbital decay. NASA provided no new altitude figure following the cancellation, but forecasts Swift will reenter the atmosphere later this year without the boost. The agency maintains the mission was still worth attempting and the takeaways hold either way.[1]
17 spacecraft detect a solar eruption hidden from Earth forecasting models
On 19 December 2024, two months after launch, the plasma instrument on NASA's Europa Clipper measured a solar wind hotter and thinner than expected. Adrienn Luspay-Kuti's team followed the signature across 17 spacecraft, including the STEREO-A observatory and the MAVEN Mars orbiter, to reconstruct an irregular coronal mass ejection. Published in Science Advances, the work shows the ejection's main body moved south and away from Earth, while a separate component travelled toward it, remaining hidden from the Earth-facing viewpoint forecasting models use. The authors consider this a concern for crewed flights between Earth and Mars, noting that a component unseen by Earth-based models can still drive shock waves that accelerate charged particles to high energies.[2]
The lunar south pole offers survival conditions for human-related microbes
NASA researchers combined Lunar Reconnaissance Orbiter elevation and temperature data with radiation exposure patterns for three candidate Artemis landing regions — Nobile Rim, Connecting Ridge, and de Gerlache Rim — to map where organisms travelling with people could last. In this simulation based on orbital measurements rather than a surface experiment, Aspergillus niger, the most ultraviolet-resistant tested species, survived for at least one Earth day without growing or reproducing, even on partly sunlit ground. Nothing multiplies on the Moon because it lacks liquid water and moderate temperatures, but survival niches range from crater floors more than a kilometre across down to a boot print. Published in Science Advances, the finding bears on planetary protection rules.[3]
