Teams at NASA's Kennedy Space Center in Florida lifted the Orion spacecraft and placed it atop the Space Launch System (SLS) Moon rocket, completing assembly for the Artemis I flight test. The spacecraft, complete with its launch abort system, was secured in place Oct. 21, 2021, and teams will begin conducting a series of tests on the fully assembled Moon rocket, now standing 322 feet tall, ahead of launch. The mission, known as Artemis I, will pave the way for a future flight test with crew before NASA establishes a regular cadence of more complex missions with astronauts on and around the Moon. With Artemis, the agency will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Astronomers recently witnessed supernova SN 2020fqv explode inside the interacting Butterfly galaxies, located about 60 million light-years away in the constellation Virgo. Researchers quickly trained NASA's Hubble Space Telescope on the aftermath. Along with other space- and ground-based telescopes, Hubble delivered a ringside seat to the first moments of the ill-fated star's demise, giving a comprehensive view of a supernova in the very earliest stage of exploding. Hubble probed the material very close to the supernova that was ejected by the star in the last year of its life. These observations allowed researchers to understand what was happening to the star just before it died, and may provide astronomers with an early warning system for other stars on the brink of death.
