NASA selects Vast for sixth private astronaut mission to ISS, targeting summer 2027 NASA and Vast have signed an order for the sixth private astronaut mission to the International Space Station, targeting launch no earlier than summer 2027 from Florida. The move marks Vast's first private crew flight and heightens competition with Axiom, which flew the prior five missions.

The Case for Moving Astronomy Off Earth: why space-based observatories matter Ground-based astronomy faces growing threats from light pollution, industrial development and proliferating satellite constellations. Moving major observatories into space would protect observations of faint galaxies and exoplanet atmospheres. The article argues for accelerated investment in space telescopes, launch capacity and international policy coordination.

Univity unveils VLEO 5G constellation to boost automotive connectivity Univity has unveiled a very-low-Earth-orbit (VLEO) 5G satellite constellation designed to address terrestrial mobile coverage gaps and performance limits in the automotive sector. The system aims to provide lower-latency, higher-capacity links to connected vehicles where ground networks are limited or congested.

Alfvén waves identified as the sustained power source for auroras A new international study co‑led by HKU and UCLA shows plasma (Alfvén) waves traveling along Earth’s magnetic field lines establish stable electric fields that accelerate electrons into the upper atmosphere, providing the sustained energy that produces auroral displays. Findings close a long‑standing gap in auroral power‑source understanding.

Univity to deploy 1,500‑satellite VLEO constellation for direct‑to‑device consumer connectivity Univity plans a 1,500‑satellite very‑low‑Earth‑orbit (VLEO) constellation to provide direct connections to consumer devices, enabling satellite‑to‑handset links without traditional user terminals. The network is pitched to deliver dense VLEO coverage with lower latency than higher‑altitude systems for mass‑market D2D services.
