Go Webb! Finally, the James Webb Telescope has opened its gimbaled antenna assembly in space! Another step by Webb on his long journey to observing the universe! Recently, according to NASA data, the James Webb Telescope opened its gimbaled antenna assembly. This antenna assembly is that little part you see in the picture above. Jame opened this ensemble at approx. over 350,000 km away from Earth, meaning approx. over 225,000 miles away from Earth. 

This process that Webb did began yesterday, December 26, 2021 at 10 a.m. EST and according to NASA, it should last an hour. However, it did not last an hour, it lasted a little longer until confirmation. But now Webb is safe with that key antenna open and continues on its way to the next step. It's a little more dangerous than this: MCC1b (Mid Course Correction Burn 1b). NASA said: "This burns fine-tunes Webb's trajectory after launch." ESA, NASA and CSA expect this new burn fine-tunes to take place today or even last until tomorrow. 

In a description on NASA James Webb Telescope website, it says: "The Cardan Antenna Assembly (GAA) has a high-rate Webb antenna. It is rotated to the Earth-facing parking position. This is an" automatic "deployment, as is the solar panel that preceded it. All other deployments will be controlled by ground commands.".

So it turns out that even if this opening of the antenna assembly is not so dangerous, it is in any case something very important for Webb. If that doesn't work out, Webb's path may not be possible. that is, it would work, but some commands would not be able to execute them. Every part and every component that Webb has means something and whatever it is, if one of the stakes or components gets stuck in the opening it can be a catastrophe.

We wish Webb continued success in his journey, but also for all those who make this mission possible!
