NASA Executes Crucial Hot-Fire Test on Artemis Rocket Engine at Stennis Space Center

Engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, successfully completed a full-duration hot-fire test on developmental RS-25 engine No. 10001. The test ran for nearly eight and a half minutes—500 seconds total—which precisely replicates the required operating time during a live launch of the Space Launch System (SLS) super heavy-lift rocket. Pushed […]

Legacy of the Neil Gehrels Swift Observatory: A Two-Decade Journey Through the Cosmos

The Neil Gehrels Swift Observatory has officially concluded its historic mission, marking the end of a transformative era in high-energy astrophysics. After more than two decades of operation—far exceeding its original two-year design life—the spacecraft has descended to an altitude of less than 171 miles. At this proximity to Earth, increased atmospheric drag has rendered […]

NASA Outlines Complex Artemis III Earth-Orbit Tests with Commercial Landers

As part of preparations for humanity’s return to the lunar surface, a major multi-spacecraft demonstration flight is taking shape to test critical systems in low Earth orbit. Scheduled for 2027, the upcoming 14-day mission will carry four spacefarers aboard the Orion spacecraft to execute complex rendezvous, docking, and operational evaluations with test versions of human […]
