"The Mid-Infrared Instrument (MIRI) and other Webb instruments have been cooling by radiating their thermal energy into the dark of space for the bulk of the last three months. The near-infrared instruments will operate at about 34 to 39 kelvins, cooling passively. But MIRI's detectors will need to get a lot colder still, to be …
Teams are preparing for the next attempt of the Artemis I wet dress rehearsal, pending range availability and restoration of propellants and gases during the test. Through the past two test runs April 3 and 4, engineers accomplished several test objectives that will prepare the teams and integrated systems for launch: Configuring Launch Pad 39B …
Payloads: AstroRad Vest: A crewmember donned the AstroRad vest, wore it for approximately 90 minutes, then doffed it and completed a survey on the device. The AstroRad vest is a personal protective equipment (PPE) device which functions as a radiation shield for astronauts. AstroRad shields astronauts from space-borne ionizing radiation in an efficient way, provides …
NASA's citizen science projects are collaborations between scientists and interested members of the public. Through these collaborations, volunteers known as citizen scientists have helped make thousands of important scientific discoveries. Aurorasaurus is one such project that tracks auroras around the world in real time via reports on its website and on Twitter. Aurorasaurus often partners …
Human research and space physics comprised the majority of the science schedule aboard the International Space Station on Tuesday. The Expedition 67 crew members also worked on U.S. and Russian cargo ships while preparing for two spacewalks. Vein and artery scans topped the day for Commander Tom Marshburn of NASA as he attached sensors to …
The Artemis I team has ended today’s attempt at the wet dress rehearsal test at 5 p.m. The countdown ended after partially loading liquid oxygen into the Space Launch System core stage tank. This provided the teams a valuable opportunity for training and to make sure modeled loading procedures were accurate. This was the first time using new systems at NASA’s …
Payloads: Airborne Particulate Monitor (APM): The crew checked the APM hardware and reported the display status. Air quality in crewed spacecraft is important for keeping astronauts healthy and comfortable. Although requirements exist for maximum allowable concentrations of particulate matter, currently no measurement capability verifies whether these requirements are met. The APM demonstrates an instrument for …
The seven-member Expedition 67 crew will wait an extra day to greet the first private astronauts who are due to launch this weekend to the International Space Station. In the meantime, the orbital residents focused on human research and physics today while gearing up for a pair of spacewalks later this month. The first private …
NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites mission, or TRACERS mission, has passed a critical mission review on March 31, 2022. The mission now moves into its next phase, advancing towards its target launch readiness date of July 27, 2024. "We're excited to pass this major milestone and get one step closer to launch," …
The countdown for the wet dress rehearsal has resumed at 10:52 a.m. EDT and clocks have picked back up at T-6 hours, 40 minutes on the clock (L-7 hours, 10 minutes). A new planned T-0 of 6:02 p.m. has been established. An earlier issue with an outage with the vendor of gaseous nitrogen required for tanking preparations has been resolved. Overnight, teams …
