2021 was a huge year for global spaceflight. Both crewed and uncrewed orbital flight reached an unprecedented level since 1957.

JWT released its first snaps:-

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

NASA’s James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.
The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyze atmospheres hundreds of light-years away.
While the Hubble Space Telescope has analyzed numerous exoplanet atmospheres over the past two decades, capturing the first clear detection of water in 2013, Webb’s immediate and more detailed observation marks a giant leap forward in the quest to characterize potentially habitable planets beyond Earth.

Artemis-1 Launch canceled. Hydrogen bleed issues (leak?)
Will know future course of action by September 2.

Engine 3 needed to meet a temperature target(had to be cooled down). They do this by flushing the excess pressure in the engine feed lines, but that bleeding mechanism was not working

They tried to test this flush mechanism during WDR(wet-dress rehearsal - simulating the launch without actually launching) but internal structure issues during WDR caused them to miss out on testing this mechanism
