The Webb Telescope is closer to starting its mission of science …
A historic look at the center of our galaxy …
And the Crew-3 astronauts reflect on their mission … a few of the stories to tell you about – This Week at NASA!
Webb Telescope in Final Phase of Instrument Setup
NASA’s James Webb Space Telescope is in the phase of its mission known as science instrument commissioning. This involves about two months of extensive calibrations and the last group of required setup activities before the telescope begins science observations this summer. A recent test image Webb took of a region of the Large Magellanic Cloud was compared to an image our Spitzer Space Telescope previously captured of that same region. The comparison demonstrates the improved clarity with which Webb can see the infrared sky. This ability could yield more detailed views of the cosmos and unprecedented discoveries.
This is the first image of Sgr A*, the supermassive black hole at the center of our galaxy. It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array that linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape. Credit: EHT Collaboration
NASA Telescopes Help Study Milky Way’s Black Hole
According to the Event Horizon Telescope Collaboration, this is the first image of the supermassive black hole, known as Sagittarius A *, located at the center of our Milky Way galaxy. The Event Horizon Telescope uses data from a worldwide network of telescopes. Observations from NASA’s Chandra X-ray Observatory, NuSTAR, and Swift Observatory were used to help astronomers study Sagittarius A*.

Crew-3 Astronauts Discuss Mission After Returning to Earth
The astronauts of NASA’s SpaceX Crew-3 mission reflected on their recent stay aboard the International Space Station during a May 11 news conference. NASA’s Kayla Barron, Raja Chari, and Tom Marshburn, along with Matthias Maurer of the European Space Agency, spent 175 days aboard the station conducting microgravity science research and technology demonstrations.
“It was just this awe-inspiring experience and incredible honor to represent the NASA team and family in that role, and also to have our relationships as a crew grow through that expeditionary living and really supporting each other so that we could get the most out of every single day in terms of accomplishing our mission.”—Kayla Barron, NASA Astronaut

NASA’s InSight Records Monster Quake on Mars
Our InSight lander on Mars has detected the largest quake ever observed on another planet. The estimated magnitude 5 quake occurred earlier this month, on May 4. The largest “Marsquake” previously recorded by InSight was an estimated magnitude 4.2 detected on August 25, 2021. A magnitude 5 quake is comparable to a medium-size quake on Earth but is close to the upper limit of what scientists hoped to see on Mars during InSight’s mission.

NASA-funded Study Grows Plants in Soil From the Moon
For the first time ever, researchers have grown the hardy and well-studied plant Arabidopsis thaliana in nutrient-poor lunar regolith samples collected during several Apollo Moon missions. The plant is a relative of mustard greens, broccoli, cauliflower, and Brussel sprouts. This NASA-funded study could help pave the way for future astronauts to someday grow more nutrient-rich plants on the Moon and elsewhere in deep space.
The Hunga Tonga-Hunga Ha’apai eruption on January 15, 2022, caused many effects, some illustrated here, that were felt around the world and even into space. Some of those effects, like extreme winds and unusual electric currents were picked up by NASA’s ICON mission and ESA’s (the European Space Agency) Swarm. Image not to scale.

NASA Mission Finds Tonga Volcanic Eruption Effects Reached Space
Data from NASA’s ICON mission has helped researchers determine that effects from the volcanic eruption on the South Pacific island of Hunga Tonga-Hunga Ha‘apai in January 2022, actually reached beyond Earth – into space. The data show that in the hours after the eruption, hurricane-speed winds and unusual electric currents formed in the ionosphere – Earth’s electrified upper atmospheric layer at the edge of space. ICON launched in 2019 to identify how Earth’s weather interacts with weather from space.
That’s what’s up this week @NASA …
