Today, at 1:17 p.m. EST, NASA’s James Webb Space Telescope completed all of its large-scale deployments with the extension and latching of its starboard primary mirror wing. Now that the telescope is structurally fully deployed – with the secondary mirror tripod and both primary mirror wings in place – the three-month process of aligning all …
The Webb mission operations team has given the ‘go-ahead’ to move forward with the extension of its starboard primary mirror panel. This is the last of the major deployments on the observatory, and its completion will set the stage for the remaining five and a half months of commissioning, which consist of settling into stable …
Webb’s iconic primary mirror is taking its final shape. Today, the first of two primary mirror wings, or side panels, was deployed and latched successfully. Each side panel holds three primary mirror segments that were engineered to fold back to reduce Webb’s overall profile for flight. The process of deploying the port side mirror wing …
Engineers have begun the final stage of Webb’s major structural deployments: the unfolding of its two primary mirror wings. These side panels, which were folded back for launch, each hold three of the observatory’s 18 hexagonal, gold-coated mirror segments. The team is beginning today with the mirror wing on the port (left) side of the …
Payloads: Acoustic Diagnostics: Acoustic Diagnostics (AUDIO) measurements were taken. The Acoustic Upgraded Diagnostics In-Orbit (Acoustic Diagnostics) investigation tests the hearing of ISS crew members before, during, and after flight. This study assesses the possible adverse effects of noise and the microgravity environment aboard the ISS on human hearing. The investigation compares the relationship between the …
Biology and agriculture were the dominant research themes aboard the International Space Station on Thursday. Also, an Expedition 66 Flight Engineer is beginning a set of record-breaking milestones before returning to Earth at the end March. NASA astronauts Raja Chari and Kayla Barron started work Thursday morning inside the Kibo laboratory module examining mice for …
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 …
