- WikiChang'e lunar program (China)China's Chang'e programme has orbited, landed on and returned samples from the Moon, including the far side. Chang'e-7 slipped from 2026 to later.Updated
- WikiCommercial space stationsPrivate stations from Vast, Axiom, Starlab and others aim to replace the ISS around 2030. Their schedules, NASA's role and the open questions.Updated
- WikiJames Webb Space Telescope (JWST)Webb is NASA, ESA and CSA's 6.5-meter infrared space telescope at L2. What it is, what it has found, and the debates it has started.Updated
- WikiMars Sample ReturnMars Sample Return was the NASA-ESA plan to bring Perseverance's rock cores to Earth. Congress declined to fund it in 2026; China's Tianwen-3 is next.Updated
