NASA Astronaut Bruce McCandless II approaches his maximum distance from the Earth-orbiting Space Shuttle Challenger in this 70mm photo from Feb. 7, 1984. While testing out the nitrogen-propelled, hand-controlled back-pack device called the manned maneuvering unit (MMU) for the first time, McCandless’s fellow crewmembers aboard the reusable vehicle photographed him. The MMU allowed crews to move outside of the cargo bay and perform activities away from the safety of the spacecraft. “It may have been one small step for Neil,” he proclaimed, “but it’s a heck of a big leap for me.” Learn how this and other iconic photos from the STS-41B mission came to be.

The longest spaceflight up to that time ended on Feb. 8, 1974, when Skylab 4 astronauts Gerald P. Carr, Edward G. Gibson, and William R. Pogue splashed down in the Pacific Ocean after their 84-day mission aboard Skylab, America’s first space station. During their stay, they carried out a challenging research program, including biomedical investigations on the effects of long-duration space flight on the human body, Earth observations using the Earth Resources Experiment Package, and solar observations with instruments mounted in the Apollo Telescope Mount (ATM). To study newly discovered Comet Kohoutek, scientists added cometary observations to the crew’s already busy sch…

This Hubble Space Telescope image shows the powerful gravity of a galaxy embedded in a massive cluster of galaxies producing multiple images of a single distant supernova far behind it. The image shows the galaxy’s location within a large cluster of galaxies called MACS J1149.6+2223, located more than 5 billion light-years away. In the enlarged inset view of the galaxy, the arrows point to the multiple copies of an exploding star, named Supernova Refsdal, located 9.3 billion light-years from Earth.Credit: NASA, ESA, and S.

NASA/JPL-Caltech Workforce statement and memo to employees. JPL statement issued on Feb. 6, 2024: After exhausting all other measures to adjust to a lower budget from NASA, and in the absence of an FY24 appropriation from Congress, we have had to make the difficult decision to reduce the JPL workforce through layoffs. JPL staff has been advised that the workforce reduction will affect approximately 530 of our colleagues, an impact of about 8%, plus approximately 40 additional members of our contractor workforce. The impacts will occur across both technical and support areas of the Lab. These are painful but necessary adjustments that will enable us to adhere to …

On Feb. 3, 1984, space shuttle Challenger took off on its fourth flight, STS-41B. Its five-person crew of Commander Vance D. Brand, Pilot Robert L. “Hoot” Gibson, and Mission Specialists Ronald E. McNair, Robert L. Stewart, and Bruce McCandless flew an eight-day mission ending with the first return to NASA’s Kennedy Space Center (KSC) in Florida. Many of the flight activities practiced tasks required for the upcoming Solar Maximum Mission satellite retrieval and repair mission. Among these, successful test flights of the Manned Maneuvering Unit (MMU) astronaut propulsion device during two untethered spacewalks proved the most critical, and visually spectacular. The two co…

7 min read Gamma-ray Bursts: Harvesting Knowledge From the Universe’s Most Powerful Explosions The most powerful events in the known universe – gamma-ray bursts (GRBs) – are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our Sun. Now thought to announce the births of new black holes, they were discovered by accident. Two neutron stars begin to merge in this artist’s concept, blasting jets of high-speed particles. Collision events like this one create short gamma-ray bursts.

The Nova-C lander will launch from NASA’s Kennedy Space Center aboard a SpaceX Falcon 9 rocket no earlier than mid-February.Credit: Intuitive Machines It’s easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game changes. Quantifying fuel that’s floating around inside a spacecraft’s tank isn’t so simple. “Because of the very small amount of gravity, fluid doesn’t sett…

11 min read The Universe is Expanding Faster These Days and Dark Energy is Responsible. So What is Dark Energy? Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay this way. Nine billion years after the universe began, its expansion started to speed up, driven by an unknown force that scientists have named dark energy. But what exactly is dark energy? The short answer is: We don’t know. But we do know that it exists, it’s making the universe expand at an accelerating rate, and approximatel…

3 min read What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays! A flash of lightning. A roll of thunder. These are normal stormy sights and sounds. But sometimes, up above the clouds, stranger things happen. Our Fermi Gamma-ray Space Telescope has spotted bursts of gamma rays – some of the highest-energy forms of light in the universe – coming from thunderstorms. Gamma rays are usually found coming from objects with crazy extreme physics like neutron stars and black holes. So why is Fermi seeing them come from thunderstorms? About a thousand times a day, thunderstorms fire off fleeting bursts of some of the highest-energy light naturally found on …

4 min read When Dead Stars Collide! Gravity has been making waves — literally. In October 2017, the Nobel Prize in Physics was awarded for the first direct detection of gravitational waves two years earlier. Also in that month, astronomers announced a huge advance in the field of gravitational waves: For the first time, they had observed light and gravitational waves from the same source. Let’s look at what happened. Two neutron stars are on the verge of colliding in this illustration. NASA’s Goddard Space Flight Center There was a pair of orbiting neutron stars in a galaxy (called NGC 4993). Neutron stars are the crushed leftover cores of massive stars (star…
