JWST
James Webb Space Telescope - the greatest space telescope we have ever created. Engineers have spent more than 20 years creating it.
The Webb Telescope is about to reveal the birth of galaxies and stars. It will also look for habitable planets to live on.
The Webb Telescope was successfully launched on December, 25.
Now JWST has reached its destination - Lagrange point 2 (I will attach some links for proper understanding). The time has come for the alignment of its 18 golden segments - mirrors that will give an opportunity to focus and take shots of the cellestial bodies. First photos are being waited in May.
By the way, we can see JWST from Earth. That is what it looks like:

First orbital satellite in space
October 4, 1957.
The Soviet Union launches the first man-made Earth orbit satellite Sputnik 1, which was designed by S. Korolev, the Soviet space program father.
Having spent 3 months in space, Sputnik 1 has made 1400 orbits.
It has made an enermous breakthrough in space history.
Next time I'll tell you about first astronauts in space. They were not men.

BTW, one of the NASA videos has the Webb orbiting the wrong way around L2. Oops.
Webb Orbit
10 points if you can explain why it's the wrong way... Hint: In the co-rotating frame, JWST's orbital plane is at an angle to the Sun-Earth line. The reason that it's at an angle is to a) conserve fuel for the insertion and b) keep the thing pointed away from the Sun while it's inserting.

JWST's first target has been detected, a star HD84406 in the constellation of Big Bear. It's a perfect object for the first try.

The James Webb Space Telescope's 1st target star is in the Big Dipper. Here's where to see it.
The Big Dipper is part of the Ursa Major constellation.
