Space.com said:The final instrument aboard the $10 billion James Webb Space Telescope finally achieved its operating temperature of just above absolute zero. The successful cooling ensures that the observatory will be able to probe cosmic objects in infrared light, according to a Wednesday (April 13) statement from NASA's Jet Propulsion Laboratory (JPL) in California, which leads U.S. work on the instrument, called the Mid-Infrared Instrument (MIRI).
The telescope has been cooling ever since its launch on Dec. 25, 2021, bringing it to the frigid temperatures necessary for MIRI to accurately detect infrared light, which manifests as heat. MIRI needs to be at a temperature is a little below 7 degrees Kelvin, which is equivalent to minus 447 degrees Fahrenheit (minus 266 degrees Celsius).
Starliner to Jeb to orbit for real; no wonder they had 2 thruster failures.
Well sure, if that's what they want to call it."retirement pose"

It's tempting to think that humans have a bird's-eye view of pretty much all of human history—we have a solid idea, that is, of who was doing what, when, and where for the last few thousand years.notthebee.com
Little bit of excitement at the Booster 7 testing for SpaceX; there wasn't supposed to be any ignition events in this round of testing.
