Moon Rocket, Lost Spacecraft, and a Comet That Fell Apart on Camera

Today on Astronomy Daily: NASA's Artemis II moon rocket has arrived at Launch Pad 39B at Kennedy Space Center, with a launch target of April 1st — the first crewed mission beyond Earth orbit in over 53 years. Plus: astronomers have discovered the first-ever mass-transferring brown dwarf binary; Hubble accidentally caught a comet disintegrating in real time; 15 new moons have been confirmed around Jupiter and Saturn; our Moon is accumulating over 100 metric tons of human-made debris; and a dramatic spacecraft double-header — ESA's Proba-3 has been recovered from a month-long blackout, while NASA's MAVEN Mars orbiter remains missing after more than three months of silence.   Story 1: Artemis II Arrives at Launch Pad 39B NASA's Artemis II SLS rocket and Orion spacecraft completed an 11-hour overnight journey to Launch Pad 39B on March 20, 2026. Launch is targeted for no earlier than April 1. The crew — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — will fly a 10-day free-return trajectory around the Moon, making this the first crewed deep-space mission since Apollo 17 in December 1972.

The system, only ~1,000 light-years away, is a prime candidate for JWST follow-up observations. Published in The Astrophysical Journal Letters.

The comet was not the original target of the observation. The findings, published in Icarus, reveal the comet is unusually carbon-depleted and raise new questions about the delay between fragmentation and visible brightening.

All are small irregular moons, discovered by combining archival telescope data with new observations. With the Vera C. Rubin Observatory now operational, further discoveries are expected.

With a wave of crewed and commercial lunar missions approaching under Artemis and beyond, space policy researchers are urging the development of international agreements to protect scientifically sensitive lunar sites before they are damaged or contaminated by human activity.

An anomaly review board is assessing options. Meanwhile, ESA's Proba-3 coronagraph spacecraft — silent since February 14 after a power failure — has been successfully recovered after engineers exploited a brief window when the tumbling spacecraft's solar panels briefly faced the Sun.
