NASA rolls Artemis II moon rocket 4 miles to LC‑39B in up-to‑12‑hour second rollout ahead of April 1 launch

NASA rolled the Artemis II moon rocket from the Vehicle Assembly Building to Launch Complex 39B in a second rollout — a roughly 4‑mile transfer expected to take up to 12 hours. The movement returns the crewed vehicle to the pad for final launch preparations ahead of an April 1 liftoff attempt.

Perseverance detects buried ancient river delta in Jezero — some of the oldest evidence of flowing water on Mars Using ground-penetrating radar in Jezero Crater, NASA's Perseverance rover has detected a buried ancient river delta that predates surface deposits seen from orbit. The discovery provides some of the oldest direct evidence that liquid water flowed on Mars billions of years ago and reveals deeper fluvial architecture for future sampling.

Meir and Williams complete 7‑hour EVA to install solar‑array modification kit, prepping ISS for roll‑out arrays NASA astronauts Jessica Meir and Chris Williams completed a 7‑hour, 2‑minute spacewalk to install a solar array modification kit on the ISS, marking Williams’ first EVA and Meir’s fourth. NASA called the operation highly productive as it prepares the station’s 2A power channel for new roll‑out arrays.

NASA's SPARCS CubeSat returns first-light images, launches M‑dwarf habitability campaign NASA's Star-Planet Activity Research CubeSat (SPARCS) has returned first-light images and begun an observing campaign targeting M‑dwarf stellar activity. The smallsat will chart ultraviolet output and energetic flares from the galaxy’s most common stars to inform assessments of exoplanet habitability.

NASA forced to choose which planetary missions to keep as program faces funding shortfall NASA’s planetary science program is confronting a budget shortfall that agency leaders say will require “strategic choices” about which missions to continue. The shortfall is driving a program-wide reprioritization as NASA evaluates ongoing and planned planetary projects against constrained funding.

Rainfall, rivers and seas on Titan: what Earth analogues teach mission planners Despite extreme cold and a hydrocarbon chemistry, Titan hosts rainfall, rivers and seas that mirror Earth's hydrological processes. Researchers are using terrestrial analogues and Earth-based observations to interpret Titan's surface, reduce mission risk, and refine landing-site and payload requirements for future Saturn-system exploration.

NASA’s X-59 preps second flight to validate low‑boom sonic signature ahead of expanded 2026 campaign NASA is preparing the X-59 experimental low‑boom demonstrator for a second flight from Edwards AFB to further validate a quieter sonic‑boom signature that could enable overland supersonic operations. The sortie — targeting about 260 mph at 20,000 ft — will set the pace for an expanded 2026 flight‑test campaign.
