This Is A Film About The James Webb Space Telescope

In this entertaining, informative, and charmingly goofy video, Dr. Kevin Hainline tells us all about the James Webb Space Telescope. The JWST is a bigger and better version of the Hubble Space Telescope and will allow scientists to peer deeper into the universe and farther back in time than ever before.

Listen, science is hard! Engineering is hard! It’s difficult to figure out how to build an incredibly sensitive infrared detector that you have to cram together on the back of a giant, foldable, gold covered mirror, sitting on a delicate, tennis-court-sized parasol, that can survive a rocket launch! It’s hard stuff!

And hundreds and hundreds of people around the world have been working on it together. JWST is the single most complicated science project human beings have ever attempted. But it’s been worth it. Because we want to discover the earliest galaxies in the universe, and clouds on other planets, and baby star-forming regions, and debris disks around stars, and weird dwarf galaxies, and supermassive black holes!

It’s been in development for almost thirty years and everyone is really ready for it! The James Webb Space Telescope is about to change astronomy. Get ready for discovery!

I am ready and excited! The JWST is currently set to launch no earlier than Dec 24, 2021. You can follow the progress of the launch here.

The First Photograph of the Far Side of the Moon from 1959

With the launch of Sputnik in 1957, the Soviet Union kicked off the Space Race and for the first several years (arguable up until the Moon landing in ‘69), they dominated the United States. One of their “firsts” in the early years was taking the first photo of the far side of the Moon 60 years ago this month.

Astronomer Kevin Hainline wrote a fascinating account of how the Soviet’s Luna 3 spacecraft took the photo and then transmitted it back to Earth.

First off, Luna 3, the first three-axis stabilized spacecraft, had to reach the Moon to take the pictures, and it had to use a little photocell to orient towards the Moon so that now, while stabilized, it could take the pictures. Which it did. On PHOTOGRAPHIC FILM.

And it gets WILDER because these photos were then moved to a little CHEMICAL PLANT to DEVELOP AND DRY THEM. That’s right, Luna 3 had a little 1 Hour Photo inside. Now you’re thinking, well, how do you get those actual photos back to the Earth?

How indeed? The spacecraft faxed the photos to Earth. A few years later, when the Soviets’ Luna 9 took the first photo on the Moon’s surface and went to transmit it back to Earth, a group in the UK was able to read the signal with a fax machine and the resulting image was published the next day on the front page of the Daily Express.
