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 …
At approximately 11:59 am EST, the fifth and final layer of Webb's sunshield was fully tensioned, marking the completion of sunshield deployment. Read more about this key milestone in preparing Webb for science operations.
With three layers of Webb's sunshield fully deployed, the team commenced tensioning – that is, pulling each layer fully taut – of the final two layers this morning. We will have live coverage of the fifth layer tensioning at nasa.gov/live beginning at about 9:30 am EST.
The Webb team has completed tensioning for the first three layers of the observatory's kite-shaped sunshield, 47 feet across and 70 feet long. The first layer – pulled fully taut into its final configuration – was completed mid-afternoon. The team began the second layer at 4:09 pm EST today, and the process took 74 minutes. …
Today, at 3:48 pm EST, the Webb team finished tensioning the first layer of the observatory's sunshield– that is, tightening it into its final, completely taut position. This is the first of five layers that will each be tightened in turn over the next two to three days, until the observatory's sunshield is fully deployed. …
Payloads: BioMole: BioMole Surface Sampling and DNA Extraction was performed. The Environmental Health System (EHS) Biomole Facility non-culture based samples are capable of providing microbial identification on-orbit within days of sampling. The goal of this Tech Demo is to conduct comparative analysis for possible replacement of current microbial monitoring systems. Cytoskeleton: The Med Reservoirs were …
