• NASA's Space Launch System (SLS) rocket for Artemis 2 began rollout from the Vehicle Assembly Building to Launch Complex 39B on March 19, targeting first motion at 8 p.m. EDT (0000 GMT March 20) for a 12-hour, 4-mile journey. • The rollout follows repairs for a helium flow issue in the upper stage, battery replacements in the flight termination system, and two prior wet dress rehearsals marred by leaks since the initial January 17 rollout. • The four Artemis 2 astronauts entered quarantine on March 18 at Johnson Space Center, limiting exposure for a week before heading to Kennedy Space Center five days before the planned April 1 launch.

• NASA's Astronomy Picture of the Day highlights NGC 1566, a grand design spiral galaxy located approximately 40 million light-years away in the constellation Dorado, known for its two prominent and graceful spiral arms traced by bright blue star clusters and red emission nebulas. • The galaxy's flaring center makes it one of the closest and brightest Seyfert galaxies, likely housing a central supermassive black hole affecting surrounding stars and gas, making it a prime target for Hubble Space Telescope observations studying star formation and supernovas. • NGC 1566 is among the most photogenic spiral galaxies in the universe, featuring a gorgeous face-on view and dark cosmic dust lanes that make it an ideal object for astronomical research and observation.

NASA’s DART mission slammed into the small asteroid Dimorphos in 2022, and the impact slowed its orbit around the larger Didymos – and also the pair’s path around the sun
