Europe’s Rocket Moment, A Hidden Cosmic Explosion, and Brown Dwarfs in Love

Astronomy Daily — Season 5, Episode 70 Monday, March 23, 2026 In today's episode, Anna and Avery cover six stories spanning a live European rocket launch attempt, a sixty-year-old NASA emergency brought back to life through newly surfaced photographs, a cosmic explosion caught only by its echo, the fight to preserve the night sky, a supply run to the ISS with an unexpected complication, and a first-of-its-kind discovery involving brown dwarf stars.

Story 1: Europe's Spectrum Rocket — Bid for Orbit Today Isar Aerospace's Spectrum rocket is attempting its second test flight today — its qualification mission for ESA's European Launcher Challenge. Launching from Andøya Spaceport in Norway, the mission carries five CubeSats and one experiment from European universities and companies, all supported by ESA's Boost! program. If successful, it would mark a landmark moment for European sovereign access to space.

A spacecraft malfunction sent the capsule into an uncontrolled spin reaching one revolution per second. Never-before-seen photographs of Armstrong's recovery have been donated to the Armstrong Air and Space Museum in Wapakoneta, Ohio.

The original explosion went unseen because its jet wasn't aimed at Earth, but the lingering radio echo has been detectable for over 1,000 days. Research published in The Astrophysical Journal.

Experts warn the proposals could permanently transform humanity's view of the night sky.

One of its KURS automated docking antennas failed to deploy after launch. Docking at the Poisk module is scheduled for March 24. If the antenna issue isn't resolved, commander Sergei Kud-Sverchkov will conduct a manual docking.

The pair orbit each other every 57 minutes at a separation smaller than the Earth-Moon distance. The system will eventually either merge into a single star or one dwarf will accrete enough mass to ignite fusion. Research published in The Astrophysical Journal Letters.
