Simultaneous Phase-Measuring Interferometer enables ability to test 16 m ROC JWST PMSA. Camera: 2k x 2k (1.3 mm/pixel at PMSA) Precision: 0.5 nm rms. who is your customer; what parameters do you need to quantify; to what level of uncertainty you must know their value; and who is your manufacturing interface?

the needed space environment. The USF Cryo-Proof Load Test, was the first test to be driven specifically by the JWST test requirements to checkout and verify new GSE . The primary objective was to induce thermal gradients in the USF by having a temperature delta between the conductively cooled top of the frame to the insulated bottom of the frame.

We're particularly excited about our special JWST show on December 1, where we will have tons of giveaways to celebrate the telescope launch. Note: in-person attendance requires attendees to follow UCLA COVID safety guidelines and provide proof of vaccination or negative COVID test within the previous 72 hours is.

2018年7月6日 · The James Webb Space Telescope (JWST) Optical Telescope Element (OTE) and Integrated Science Instrument Module (ISIM) completed their element level integration and test programs and were integrated to the next level of assembly called OTE/ISIM (OTIS) at Goddard Space Flight Center (GSFC) in Greenbelt, Maryland in 2016.

4 天之前 · The James Webb Space Telescope (JWST) continues to push the boundaries of space exploration, providing astronomers with an unparalleled opportunity to study the universe in unprecedented detail. Now, with Cycle 4 of the General Observer (GO) program, JWST is set to expand our understanding of the cosmos like never before. ... Test current ...

Matthews’ team of technicians put together the model, according to Phys.org, which will “stand in for the real thing in an upcoming test at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dubbed Core-2, the test will verify that Webb can regulate its core body temperature to the correct specifications.”
