Space & Astronomy Watch: Week of October 5, 2026

Overview

This week brought a mix of commercial station planning, crew return, reentry technology testing, and solar and planetary science. NASA moved its commercial low Earth orbit plans forward with a final call for proposals, while a crewed mission ended safely in the Pacific. Science results from ESA missions also advanced understanding of the Sun and Mars.

Key developments

  • NASA released its final Request for Proposals on 2026-10-09, inviting US industry to submit plans for next-generation commercial space stations in low Earth orbit.

  • SpaceX Crew-12 splashed down off California on 2026-10-08, returning NASA astronauts Jessica Meir and Jack Hathaway, ESA's Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev aboard Crew Dragon Freedom.

  • NASA flew 12 small experimental capsules on Northrop Grumman's 24th cargo resupply mission, releasing them after undocking to test heat shields for Moon and Mars returns, as reported on 2026-10-09.

  • ESA's Solar Orbiter flew through an S-shaped magnetic switchback and traced its particles back to the Sun's surface, per 2026-10-09 items.

  • Mars Express and a weather model suggested exotic physics behind Mars's strangest cloud, also reported on 2026-10-09.

What to watch

  • How US industry responds to NASA's final RFP for commercial space stations, and what proposals emerge.

  • Results from the 12 heat-shield capsules released after the cargo mission's undocking, which could inform future Moon and Mars return designs.

  • Further analysis of Solar Orbiter's switchback data and Mars Express's cloud findings as scientists refine their models.
