Spreading its mirror wings was the telescope’s last big step in its complicated deployment.


NASA has pulled off the most technically audacious part of bringing its newest flagship observatory online: unfolding it.

On Saturday, Jan. 8, the operations team for the James Webb Space Telescope (JWST) announced that the observatory’s primary mirror had successfully unfolded its segments — the last major step of the telescope’s complicated deployment.

The moment was a euphoric moment of validation for the entire team. “We’re on an incredible high right now,” said Bill Ochs, JWST’s project manager, at a press conference. “Today represents the beginning of a journey for this incredible machine, to its discoveries that we’ll be making in the future.”

The first galaxies in the universe are a mystery to us — but that could soon change.


The cosmos has come a long way (pun intended). But the most fantastic story of all time isn’t fully understood — especially the early chapters, ‘written’ in history during the first two to three hundred million years of the universe’s 13.8 billion-year existence.

The James Webb Space Telescope could be the key. The observatory can look about three times as far back in time than the iconic Hubble. The Webb will detect infrared wavelengths long enough to pierce through the dense smog of all the light and dust that sits between Earth and the furthest galactic posts, revealing information about the ancient universe where these wavelengths began their journey through space billions of years ago.

Although not quite yet ready to collect data, the Webb Telescope promises a level of perception made possible by its four instruments. These instruments can operate at the same time to siphon observations of objects like galaxies — maximizing the efficiency of the telescope.

Scientists have confirmed the speed of sound on Mars, using equipment on the Perseverance rover to study the red planet’s atmosphere, which is very different to Earth’s.

What they discovered could have some strange consequences for communication between future Martians.

The findings suggest that trying to talk in Mars’ atmosphere might produce a weird effect, since higher-pitched sound seems to travel faster than bass notes. Not that we’d try, since Mars’ atmosphere is unbreathable, but it’s certainly fun to think about!

Nearly 50 years after it was collected, a lunar sample from the Apollo 17 mission has finally been opened at NASA’s Johnson Space Center in Houston. It’s one of the last unopened samples from the final Apollo mission to land humans on the moon.

“We have had an opportunity to open up this incredibly precious sample that’s been saved for 50 years under vacuum and we finally get to see what treasures are held within,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, in a statement.

It was collected by NASA astronauts Eugene Cernan and Harrison “Jack” Schmitt in December 1972 when they hammered 14-inch (36-centimeter) cylindrical drive tubes into a landslide deposit in the Taurus-Littrow Valley. The two astronauts vacuum-sealed the tube while still on the lunar surface.
