Hydra009

Executive summary: this telescope is a bigger, better, more badass Hubble and it'll help us find exoplanets, discover galaxies, and peer back to the beginning of the universe.

Two decades of hard work by some of the finest minds on the planet.  Scheduled to launch Christmas Eve 2021.  Fingers crossed.

Did they checked the damned mirror this time?

We'll see.  It'll be at Lagrange point 2 (basically, hiding behind Earth's shadow in order to keep its sensitive sensors as cool as possible) 1,500,000 km away from the Earth (about 4 times the distance to the moon), so it'll be too far away to service should something go wrong.  In comparison, the Hubble is a mere 540 km away.

Holy crap!  These guys are getting serious about looking into outer space.  I went to a lecture by some Cal Tech guys who said we can't see the beginning of the universe, because the lights didn't come on until 250,000 years later.  I think at time, they were approaching the 250,000 year event.  I'm still hoping we will be able to see the beginning without the aid of light.  Surely if something happened, our guys must be smart enough to detect it.

Well, we think we have already detected it, but we didn't know what it was when we did. It's the back ground radiation that you can see on your TV when it's tuned to an empty channel, but I'm hoping for something more dramatic than that.

Launch pushed back to Christmas Day.

Saw an interesting graphic the other day. Picture ~ a dozen (didn't count them.) hexagons (JWT mirror). The Hubble mirror would cover the center hex and a bit of the surrounding hexs. The outer ring of hexs were more than one diameter away from the Hubble mirror. The ghost of Galileo is drooling somewhere out there. Ah, found it.

It's on the way!  Final orbit will be 1 million miles from earth.

There don't appear to be any anti-maskers at all in the control center.

6 months until they start their first science missions. :(

Hopefully we will get to see some of the focusing and alignment shots.

My brother asked why the countdown was in French and if they're launching from France.  🤦‍â™,️

(It launched from French Guiana, in cloudy weather no less)

We are fresh out of space shuttles if it doesn't deploy correctly. Perhaps Bezos can do a spacewalk if needs be.

So far, so good!  The real test will be the deployment of the sunshield.

They have a squadron of Teslas ready if needed.
