ESA/Webb, NASA & CSA, A. Adamo (Stockholm University) and the FEAST JWST team The James Webb Space Telescope observed “starburst” galaxy NGC 4449, seen in this image released on May 29, 2024. Starbursts are intense periods of star formation usually concentrated at a galaxy’s core, but NGC 4449’s activity is much more widespread — likely due to past interactions with its galactic neighbors. Astronomers can study this galaxy to look into the past: NGC 4449 is similar to early star-forming galaxies, which also grew by merging with other systems. See more Webb images from this year.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Earth’s polar regions radiates much of the heat initially absorbed at the tropics out to space, mostly in the form of far-infrared radiation. Clouds in the Arctic — like these seen over a Greenland glacier — and Antarctic can trap far-infrared radiation on Earth, increasing global temperatures.NASA/GSFC/Michael Studinger Information from the PREFIRE mission will illuminate how clouds and water vapor in the Arctic and Antarctic influence the amount of heat the poles radiate into space. A pair of new shoebox-size NASA satellites will help unravel an atmospheric mystery that’s bedeviled sc…

How does spaceflight affect tumor-bearing fruit fly hosts and their parasites? Pigmentation: A side-by-side comparison of wasps shows a clear difference in the melanization of wing veins for wild-type and each mutant. Blade Shape: The kona mutant has an angular wing shape in contrast to wild-type’s rounded wing blade (vertical arrows in D–F).S. Govind. Background: Like humans, fruit flies (a model organism for spaceflight research) also exhibit immune system dysfunction in space. Despite decades of studies on fruit flies and wasps, little was known about how their immune systems interact with natural parasites in space. Drosophila parasitoid wasps modify blood cell fu…

On May 27, 1999, the second space station assembly and logistics mission began. The main goals of STS-96, designated as the 2A.1 mission in the overall assembly sequence, included resupplying and repairing the fledgling orbital facility, consisting of the Zarya and Node 1 modules assembled during STS-88 in December 1998. The multinational seven-member crew transferred nearly two tons of supplies from the shuttle’s Spacehab double module and water to the crew-tended space station. Two of the astronauts conducted a spacewalk to install equipment on the outside of the facility. The astronauts also conducted repairs inside the station. After six days of docked operations in l…

After ten months in orbit, the Starling spacecraft swarm successfully demonstrated its primary mission’s key objectives, representing significant achievements in the capability of swarm configurations. Swarms of satellites may one day be used in deep space exploration. An autonomous network of spacecraft could self-navigate, manage scientific experiments, and execute maneuvers to respond to environmental changes without the burden of si…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Images from the November 2023 flyby of asteroid Dinkinesh by NASA’s Lucy spacecraft show a trough on Dinkinesh where a large piece — about a quarter of the asteroid — suddenly shifted, a ridge, and a separate contact binary satellite (now known as Selam). Scientists say this complicated structure shows that Dinkinesh and Selam have significant internal strength and a complex, dynamic history. Panels a, b, and c each show stereographic image pairs of the asteroid Dinkinesh taken by the NASA Lucy Spacecraft’s L’LORRI Instrument in the minutes around closest approach on Nov. 1, 2023.

Lee English Jr., left, and his son, Noah, follow in the footsteps of the late Lee English Sr. by working at NASA’s Stennis Space Center. English Sr., an engineer working for the Rocketdyne Division of Rockwell International Corporation in the 1970s, is credited with conducting the first seven engine tests for NASA’s new Space Shuttle Program, paving the way for RS-25 engine testing at NASA Stennis. The RS-25 engine, manufactured by Aerojet Rocketdyne, an L3 Harris Technologies company, is an evolved version of the space shuttle main engine.NASA/Danny Nowlin For Lee English Jr., the sound of a ringing phone probably sounds a lot like the roar of a rocket engine test at N…

Earth planning date: Tuesday, May 28, 2024 For the last several months, Curiosity has been steadily climbing through the bedrock layers of the upper sulfate unit. While each stop had its own collection of bedrock blocks tilting one way or another, you could imagine putting each scene back together into one coherent package of layers, undoing the work that erosion and time had wrought. In Curiosity’s current location, Gediz Vallis, the puzzle is not so neatly put back together. The valley f…

He and the other two crew members already in the raft, Thomas P. Stafford (left) and John W. Young, were brought to the prime recovery ship, USS Princeton after splashdown. The Apollo 10 mission was the first flight of a complete, crewed Apollo spacecraft to operate around the Moon. It encompassed all aspects of an actual crewed lunar landing, except the landing.

Credit: JPL-Caltech The discovery A planet thought to orbit the star 40 Eridani A – host to Mr. Spock’s fictional home planet, Vulcan, in the “Star Trek” universe – is really a kind of astronomical illusion caused by the pulses and jitters of the star itself, a new study shows. Key facts The possible detection of a planet orbiting a star that Star Trek made famous drew excitement and plenty of attention when it was announced in 2018.
