NASA's launch window in February is getting smaller.

The Wet Dress Rehearsal is a critical test of the fueling and countdown of NASA's SLS rocket, which could launch a crew of four as early as Feb. 6.

The buzz is building for NASA’s Artemis II mission that will send four astronauts on a 10-day voyage around the moon. The highly anticipated endeavor will be the first crewed moon-bound flight since the final Apollo mission way back in 1972.

How well Artemis II manages its risks — untested hardware, deep-space distance, and limited escape options — will shape NASA's plans for future lunar landings and, potentially, human missions to Mars. A serious failure could revive long-standing questions about whether the dangers of deep space still justify sending people there.

NASA's Artemis II SLS (Space Launch System) rocket and Orion spacecraft, secured to the mobile launcher, is seen inside the Vehicle Assembly building as preparations continue for roll out to Launch Pad 39B, Thursday, Jan. 15, 2026, at NASA's Kennedy Space ...

Mars has always felt like a distant neighbor, reachable only after a long, risky cruise through deep space. Now engineers inside NASA are sketching a very different future, one where a nuclear powered spacecraft could sprint to the red planet in roughly a month and a half instead of most of a year.

NASA’s Artemis II is set to depart on a 10-day crewed mission around the Moon, with astronauts aboard the Orion spacecraft atop the Space Launch System (SLS) rocket. This mission is targeted to launch no earlier than Feb. 6. Nasa’s Artemis Ii ...

NASA will roll a 322-foot-tall rocket out to the launchpad on Saturday, a key step as the agency prepares for a long-awaited mission to send four astronauts around the moon. The Space Launch System rocket, topped with the Orion capsule, which will carry ...
