Engineers have completed filling the core stage liquid hydrogen tank, and have moved into the replenish phase. Core stage liquid oxygen fast fill is still underway. Although the LH2 tank is larger than the LOX tank, LOX is denser than LH2 and takes longer to load. Teams continue to work toward a two-hour launch window …
Fast fill operations are underway for the Space Launch System rocket’s core stage liquid oxygen and liquid hydrogen tanks.
Expedition 68 Flight Engineers Josh Cassada and Frank Rubio of NASA concluded their spacewalk at 4:25 p.m. EST after 7 hours and 11 minutes in preparation for upcoming solar array installation. Cassada and Rubio completed the majority of the primary objectives for today to assemble a mounting bracket on the starboard side of the station’s …
Teams have begun the slow fill phase to load liquid hydrogen (LH2) and liquid oxygen (LOX) into the Space Launch System rocket’s core stage. Once LH2 and LOX slow fill is complete, teams will transition to fast fill operations. Below are the as scheduled times for slow and fast fill operations: 4:24 p.m.: Core stage …
USOS Extravehicular Activity (EVA) #81 (1B IROSA Prep): Today, Josh Cassada (EV1) and Frank Rubio (EV2) performed the 1B ISS Roll Out Solar Array (IROSA) Prep EVA. Hatch opening occurred at 8:13 AM CT. The main goal of this EVA was to route cables on both the 3A and 1B Mod kits and install the …
Artemis Launch Director Charlie Blackwell-Thompson has given the “go” to officially begin loading propellants into the Space Launch System rocket. Tanking begins with chilldown of the core stage liquid oxygen and liquid hydrogen transfer lines. NASA TV coverage begins at 3:30 p.m. EST at http://www.nasa.gov/live
The Artemis I mission management team met today to review the status of operations and has given the “go” to proceed toward tanking operations. Weather conditions are 80% favorable for the two-hour launch window which opens at 1:04 a.m. EST Nov. 16, with the primary concern being the potential for thick clouds. Launch director Charlie …
Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft. NASA's James Webb Space Telescope was engineered to withstand continual bombardment from these dust-sized particles moving at extreme velocities, to continue to generate groundbreaking science far into the future. "We have experienced 14 measurable micrometeoroid hits on our primary mirror, and are averaging one to …
Expedition 68 Flight Engineers Josh Cassada and Frank Rubio of NASA began a spacewalk at 9:14 a.m. EST to assemble a mounting bracket on the starboard side of the station’s truss assembly in preparation for the installation of a pair of International Space Station Rollout Solar Arrays on the space station. Cassada, designated extravehicular crew …
