Artemis 1: Nasa abandons second moon rocket launch try after gas leak
Nasa first tried to launch Artemis I, which consists of the SLS rocket and Orion spacecraft, on 29 August, however climate issues, a defective valve and issues bringing one of many rocket’s engines to the right preflight temperature led the area company to clean the launch.
In September, Nasa couldn’t cease leaks within the interface between the liquid hydrogen gas line and the SLS rocket’s gas tank, resulting in a scrubbed launch.
Nasa has since changed seals on the interface and altered its cryogenic gas loading procedures, and Wednesday’s check is meant to see if these adjustments will probably be adequate to repair the leaks previous to the following launch try. Nasa will load the SLS core and higher stage gas tanks in the course of the check, however will maintain the rocket powered down.
If all goes effectively, Nasa hopes to attempt for a launch on 27 September, with a again up date of two October.

SLS will launch Orion on a greater than month-long mission to fly across the Moon, testing out the spacecraft’s flight programs, earlier than returning to Earth and splashing down within the Pacific ocean.
If Artemis I is successful, Artemis II will comply with in 2024, the place 4 Nasa astronauts will fly an identical flight path across the Moon and again to Earth. Artemis III, scheduled for 2025, will see two astronauts lastly set foot on the Moon once more for the primary time since 1972.
