The ESSCA II contract will deliver engineering and science services for NASA centers, including Marshall Space Flight Center.

NASA engineers have completed first cold-flow tests of a full-scale nuclear thermal propulsion reactor, validating designs for future deep-space missions.

On February 3, 2026, NASA will run Artemis II White Dress Rehearsal. Engineers will fuel the rocket, simulate countdown and ensure the Orion spacecraft is mission-ready for lunar flight.

Cold-flow tests at NASA Marshall demonstrated the stability of a nuclear propulsion design aimed at reducing travel times to the moon and Mars.

Nuclear propulsion and power technologies could unlock new frontiers in missions to the moon, Mars, and beyond. NASA has reached an important milestone advancing nuclear propulsion that could benefit future deep space missions by completing a cold-flow test campaign of the first flight reactor engineering development unit since the 1960s.

NASA faces high stakes as Artemis II undergoes a high-risk Wet Dress Rehearsal, testing its ability to carry astronauts to the Moon.

A team of four high school students from Brampton are developing a satellite diagnostic tool they say could one day be used by NASA and space engineering companies around the world.

The first crewed lunar mission in more than 50 years is on hold as winter weather in Florida forces NASA to push back launch plans for Artemis II. The agency says near-freezing temperatures and strong winds at Kennedy Space Center prompted managers to delay a crucial fueling test — known as the wet dress rehearsal

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.

A Q+A with Rebecca Lawler and Imelda Muller, two Hopkins affiliates who are among 10 individuals selected from a pool of more than 8,000 applicants for NASA's 2025 astronaut class.
