As NASA’s James Webb Space Telescope makes its way out to its intended orbit, ground teams monitor its vitals using a comprehensive set of sensors located throughout the entire spacecraft. Mechanical, thermal, and electrical sensors provide a wide array of critical information on the current state and performance of Webb while it is in space. …
At about 8:48 a.m. EST, a specialized radiator assembly necessary for Webb’s science instruments to reach their required low and stable operating temperatures deployed successfully. The Aft Deployable Instrument Radiator, or ADIR, is a large, rectangular, 4 by 8-foot panel, consisting of high-purity aluminum subpanels covered in painted honeycomb cells to create an ultra-black surface. …
Engineers and technicians continue to complete integrated tests inside the Vehicle Assembly Building at NASA’s Kennedy Space Center as part of the lead up to launch of the Artemis I mission. On Dec. 17, the team completed a communications end-to-end test to ensure the rocket, spacecraft and ground equipment can communicate with the consoles in …
Payloads: Analyzing Interferometer for Ambient Air-2 (ANITA-2): ANITA-2 hardware was installed into an EXPRESS Rack. Power cables were mated, and the facility was powered up followed by photo documentation. The ANITA-2 is a compact gas analyzer which can analyze and quantify 33 trace contaminants in the atmosphere aboard the ISS automatically. ANITA-2 can also detect …
Space biology work and science hardware maintenance and were the main research goals for the Expedition 66 crew aboard the International Space Station on Wednesday. The orbital residents also checked out life support gear and worked on cargo transfers. Three NASA astronauts, Mark Vande Hei, Thomas Marshburn and Kayla Barron, joined each other in the …
Today, Webb teams successfully deployed the observatory’s secondary mirror support structure. When light from the distant universe hits Webb’s iconic 18 gold primary mirrors, it will reflect off and hit the smaller, 2.4-foot (.74-meter) secondary mirror, which will direct the light into its instruments. The secondary mirror is supported by three lightweight deployable struts that …
While the Webb team was tensioning the sunshield, other activities were also taking place among the instruments. One milestone: unlocking the Mid-Infrared Instrument (MIRI) Contamination Control Cover. We’ve asked Gillian Wright, European principal investigator for MIRI, to tell us about it. “MIRI has a Contamination Control Cover, because the constraints of its extra-cold operating temperature …
As expected, the Webb original deployments timeline has changed over time. Sunshield tensioning was completed today, on the 10th day after launch. The secondary mirror deployment is now planned for tomorrow morning. Live coverage of the deployment, from the Webb Mission Operations Center at the Space Telescope Science Institute in Baltimore, Maryland, will stream on …
Payloads: Airborne Particulate Monitor (APM): A crewmember removed the SD Card from APM, transferred its data to an SSC laptop, and re-insert the SD Card back into APM. 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 …
Crew Dragon proficiency checks were on the schedule for a pair of NASA astronauts aboard the International Space Station on Tuesday. Eye checks, space biology research, and spacewalk preparations also kept the Expedition 66 crew busy throughout the day. The SpaceX Crew Dragon Endeavour, which delivered four astronauts to the orbiting lab, has been docked …
