Most powerful space telescope ever built gets a new launch date

The most powerful space telescope ever built is set to launch on December 18, NASA has announced.

But with so many delays affecting the James Webb Space Telescope’s deployment over the years, many observers may not believe the new schedule until they actually see the rocket blasting into space with the telescope tucked away in the fairing.

The James Webb Space Telescope will launch aboard an Arianespace Ariane 5 rocket from Europe’s Spaceport in French Guiana on the northeastern coast of South America. Once in orbit almost a million miles from Earth, the telescope will serve as the premier deep space observatory for the next decade.

NASA said the telescope’s advanced technology will enable scientists to explore “every phase of cosmic history — from within our solar system to the most distant observable galaxies in the early universe, and everything in between,” adding that “Webb will reveal new and unexpected discoveries, and help humankind understand the origins of the universe and our place in it.” And if the work of the existing Hubble Space Telescope is anything to go by, we can expect to enjoy plenty of jaw-dropping imagery from the new technology.

The result of an international collaboration between NASA, the European Space Agency, and the Canadian Space Agency, the highly advanced James Webb Space Telescope features a striking 6.5-meter-diameter golden mirror made up of 18 hexagonal segments that will allow it to explore deep space in greater detail than ever before.

The mirror also includes an enormous sunshield about the size of a tennis court. As both the mirror and the sunshield are too large in their open form to be placed inside the rocket’s fairing, both components will be carefully folded for the flight and then automatically unfold soon after deployment.

Launch day has certainly been a long time coming. Development on the project started way back in 1996 with a launch date originally targeted for 2007. But various issues along the way, including the ongoing coronavirus pandemic, saw a number of mission dates called off.

Barring any last-minute calamities, it really does look as if the most powerful space telescope ever built will soon be heading skyward.

After calling off the launch of Boeing Space’s Starliner spacecraft on Saturday with just minutes to go, NASA says it's now aiming to send the vehicle on its first crewed mission at 10:52 a.m. ET on Wednesday, June 5.

James Webb discovers the most distant galaxy ever observed
JADES (NIRCam Image with Pullout). The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy. This corresponds to a time less than 300 million years after the big bang.

Researchers using the James Webb Space Telescope have discovered the most distant known galaxy to date, one that is so far away that it existed just a few hundred million years after the Big Bang. Since Webb began its science operations in 2022, astronomers have used it to look for very distant, very ancient galaxies and have been surprised by what they found. Not only have they found many of these distant galaxies, but the galaxies are also brighter and more massive than they expected -- suggesting that galaxies evolved into large sizes faster than anyone imagined.

NASA had been hoping to perform the first crewed launch of the troubled Boeing Starliner capsule this weekend, but now the launch has once again been delayed, with no new date yet announced.
