After their historic journey around the Moon, the Artemis II astronauts are coming home. Watch as they arrive in Houston, Texas, home to NASA's Johnson Space Center.

NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen splashed down in the Pacific Ocean on April 10, 2026, concluding the Artemis II mission. The crew accomplished many milestones on their 10-day mission, surpassing the Apollo 13 record for farthest crewed spaceflight and observing the lunar surface like never before, capturing iconic views.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

DESI Completes Planned 3D Map of the Universe and Continues Exploring

The Dark Energy Spectroscopic Instrument, one of the most extensive surveys of the cosmos ever conducted, finished all observations for its originally planned 3D map of the Universe.

DESI has mapped more than 47 million galaxies and quasars, creating the largest high-resolution 3D map of our Universe to date. Because of the instrument’s excellent performance and hints that dark energy might evolve, DESI will continue observations into 2028 and further expand the map. DESI was constructed with funding from the U.S. Department of Energy Office of Science and is mounted on the U.S. National Science Foundation Nicholas U. Mayall 4-meter telescope.

This is the future. There are too many restrictions and red tape for building more power plants on earth. In some countries planning and fighting objections could take 5-15 years!
