Astroscale UK has secured a €399,000 Phase A contract from the European Space Agency to design the In‑Orbit Refurbishment and Upgrading Service (IRUS), a world‑first capability to repair satellites in space. The eight‑month study will evaluate technical feasibility and commercial viability, with BAE Systems joining as a prospective customer to test upgrades on a modular platform. IRUS builds on Astroscale’s rendezvous expertise and aligns with ESA’s Space Safety Programme to curb orbital debris. Success could transform satellites from disposable assets into reusable, upgradable hardware.
Researchers Scott and Dransfield propose a broader "temperate zone" for exoplanet habitability, defined by instellation fluxes between 0.1 and 5 times Earth’s. Their study introduces two new planets—Earth‑sized TOI‑6716 b and sub‑Neptune TOI‑7384 b—orbiting fully convective M dwarfs, both lying near the...
ESA’s Comet Interceptor, originally slated to share an Ariane 6 launch with the Ariel exoplanet mission in 2029, will now launch earlier as a co‑passenger with a commercial communications satellite on an Ariane 64 between August 2028 and July 2029. The schedule change avoids...
