Good Thursday morning my Brothers and Sisters in Arms! it is an overcast start to the day here in SW Florida with a temp of only 62° with a chance of rain in about 20 minutes or so, followed by cloudy to partly cloudy skies and warming up to about 73° at 1 PM...
That said, the JWST is doing great this morning as the Hot and Cold sides of it are within the desired acceptable temperatures... The JWST has now completed some 84.2294 % of its planned trek to Lagrange Point L2, where it will enter into a predetermined orbit about the L2 Point! As I have mentioned in the past, the L2 point is where the gravitational pull of the Sun is directly offset by the gravitational pull of Planet Earth...thus making this point a stable one for the JWST as it will neither drift out further into space or drift in closer to Earth...
The cruising speed has slowed down considerably from when it was launched and is now at a speed of 0.1947 Miles/second... Still pretty fast by Earth standards... Also, the scientists and engineers are still calibrating the 18 mirror segments so that they will function in unison to one perfect setting as a single mirror... Remember that this telescope does not "see" visible light, but ultraviolet radiation light as the light from so deep in the universe has become stretched so-to-speak into the ultraviolet frequency range...
It is able to observe celestial bodies, such as stars, nebulae and planets, that are too cool or too faint to be observed in visible light -- what is visible to the human eye. Infrared radiation is also able to pass through gas and dust, which appear opaque to the human eye, according to NASA.
This is different from the Hubble Telescope, which sees visible light, ultraviolet radiation and near-infrared radiation.
I hope you keep watching and learning about the JWST...
Kerry
