NASA aims to make Space Coast a place for launchers of all sizes — small rockets included

In the coming months, Launch Complex 48 (LC-48) will become as talked about as all of the other launchpads on Florida’s Space Coast. NASA has been working on the development of this pad to be used by multiple launch providers with smaller classes of rockets. According to a press release issued today, they’ve set a limit of 500,000 pounds of thrust or less at liftoff.

SLS: NASA proceeding with wet dress rehearsal next week after fuel temperature paused test

NASA is preparing to send the first woman and next man to the Moon in this decade with the Artemis program. Our return to the Moon won’t be like the Apollo program, however, as NASA wants to return in a sustainable fashion: lunar orbit station called gateway, Moon base called Artemis Base Camp, and international partnerships.

The agency briefly paused a critical step in testing the core stage of its new Space Launch System rocket at Stennis Space Center this week. NASA now says it will resume what’s called the wet dress rehearsal test next week. Launching NASA’s Space Launch System rocket and sending the Orion spacecraft around the Moon next year on the Artemis I mission is key to pushing forward with the Artemis program.

The team at the space center in South Mississippi briefly suspended fueling the rocket core stage on Monday after liquid oxygen temperature readings outside of the expected range were detected. Officials described the issue as operational and not caused by the rocket core stage. Now the team believes it has readjusted its fueling procedure to hit the target LOX delivery temperature.
