Astronomy Daily: Space News Updates

Astronomy Daily Season 5, Episode 80 — Friday, April 3, 2026  It's Day 2 of the Artemis II mission and the crew is on their way to the Moon after a perfect translunar injection burn. We've also got a comet about to face perihelion, a dark matter mystery deepening, stunning new JWST images, and the escalating fight over the future of our night skies.  In today's episode:  🚀 ARTEMIS II — TRANSLUNAR INJECTION BURN: The Orion spacecraft successfully completed its TLI burn on April 2, sending four astronauts toward the Moon for the first time since Apollo 17 in 1972. Canadian astronaut Jeremy Hansen delivered one of the quotes of the year from orbit.  🚽 ARTEMIS II — THE LUNAR LOO: Hours after launch, Orion's toilet malfunctioned. Christina Koch fixed it. This is why test flights exist.  ☄️ SUNGRAZER COMET C/2026 A1 (MAPS): Tomorrow, this Kreutz sungrazer passes 161,000 km from the Sun's surface. It could vaporise — or become the most spectacular comet since Ikeya-Seki. Southern Hemisphere watchers: eyes on the western horizon from April 6.  🌌 DARK MATTER-FREE GALAXIES: Yale astronomers have confirmed a third galaxy with essentially no dark matter — NGC 1052-DF9. The 'Bullet Dwarf' collision theory is gaining powerful evidence.  🌟 JWST + W51: The James Webb Space Telescope has revealed hidden young stars in the W51 star-forming region, piercing dust clouds that have blocked our view for decades.  ⚠️ NIGHT SKY UNDER THREAT: Reflect Orbital's orbital mirror satellite launches this month. SpaceX wants one million satellites. The astronomical community is fighting back.  Find us at: http://astronomydaily.io Follow us: @AstroDailyPod Part of the Bitesz.com Podcast Network

Today is the day. Artemis II — NASA's first crewed Moon mission in 54 years — lifted off last night, and as we record this, four astronauts are preparing to leave Earth's orbit forever on the Translunar Injection burn. In this special launch-day edition, Anna and Avery cover the near-flawless launch, today's critical TLI milestone, the historic firsts being set by the crew aboard Orion (named Integrity), what the next ten days look like on the road to the Moon, the international CubeSats that hitched a ride, and the stunning coincidence of a full Pink Moon rising as humanity headed moonward.   Key Sources •      NASA Liftoff Announcement — nasa.gov •      NASA Artemis Live Updates Blog — nasa.gov/blogs/artemis •      NASA Coverage Schedule — nasa.gov/missions/artemis •      CNN Artemis II Live Updates — cnn.com •      Time Magazine — 'The Lunar Mission the World Is Watching' •      Astronomy.com — Live Updates: Artemis 2 •      NPR — NASA Launches Four People on Artemis II •      Wikipedia — Artemis II •      FAI World Air Sports Federation — Artemis II Records •      Fast Company — Pink Moon / Artemis II   Upcoming Mission Milestones •      Tonight, April 2 (~8 PM ET): Translunar Injection burn — crew leaves Earth orbit •      Sunday, April 5: Crew communication downlinks; Apollo 13 distance record expected to be broken •      Monday, April 6: Lunar flyby — closest approach ~4,000 miles from Moon surface •      Friday, April 10: Pacific Ocean splashdown

Launch day has arrived. In this episode of Astronomy Daily, Anna and Avery countdown to tonight's historic Artemis II launch — humanity's first crewed lunar mission since 1972 — and explore the dramatic stories unfolding alongside it: a sungrazing comet faces its moment of truth just three days from perihelion; astronomers raise urgent alarms over plans for one million new satellites; the interstellar comet 3I/ATLAS leaves its open-data legacy; and fascinating new science unpacks the hellish reality of Venus and a creative low-tech solution for mapping the Moon's interior.
