In space since their launch on Nov. 16, 1973, Skylab 4 astronauts Gerald P. Carr, Edward G. Gibson, and William R. Pogue began the new year of 1974 roughly halfway through their planned 84-day mission. By the end of January, the three rookies held the records for the longest single space flight and the most cumulative time spent in space. Mission managers monitored the station’s and the astronauts’ health and weekly concurred with extending the mission to its full duration as the astronauts accomplished a record number of science observations of the Sun, the Earth, Comet Kohoutek, and themselves. Carr and Gibson completed the final Skylab spacewalk to bring inside externa…

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, seen here in an artist’s concept, is scheduled to launch no earlier than Feb. 6, 2024, to study Earth’s oceans, atmosphere, and climate. NASA/Conceptual Image Laboratory NASA will host a media teleconference at 12 p.m. EST, Wednesday, Jan. 17, to discuss the upcoming launch and science objectives of the agency’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission. Once in orbit above Earth, the satellite will shed light on the impact of tiny things – microscopic life in water and microscopic particles in the air. With new global insights, PACE will help answer questions about how our oceans and at…

6 Min Read NASA’s PACE To Investigate Oceans, Atmospheres in Changing Climate Earth is complex – the atmosphere, ocean, land, and each small interwoven facet of those systems is a puzzle piece that connects and fills out the full picture. With a changing climate, the puzzle is becoming more complex – and important – to understand. Credits: NASA / Ryan Fitzgibbons and Emme Watkins Earth’s oceans and atmosphere are changing as the planet warms. Some ocean waters become greener as more microscopic organisms bloom. In the atmosphere, dust storms born on one continent affect the air quality of another, while smoke from massiv…

NASA/Brandon Torres NASA astronaut Nicole Mann and U.S. Representative Zoe Lofgren talk with students and families at Youth Alliance, a community organization in Hollister, California, on Jan. 5. Mann, who was born in another small California community, spoke about her parents’ work as an auto mechanic and a manicurist and her own path to becoming a colonel in the U.S. Marine Corps. Later, she said, becoming the first indigenous woman from NASA to go to space helped her connect with people of other indigenous communities. Mann is registered with the Wailacki of the Round Valley Indian Tribes. Lofgren, the ranking member of the House Science, Space, and Technol…

5 min read NASA’s Fermi Detects Surprise Gamma-Ray Feature Beyond Our Galaxy This artist’s concept shows the entire sky in gamma rays with magenta circles illustrating the uncertainty in the direction from which more high-energy gamma rays than average seem to be arriving. In this view, the plane of our galaxy runs across the middle of the map. The circles enclose regions with a 68% (inner) and a 95% chance of containing the origin of these gamma rays. NASA’s Goddard Space Flight Center Astronomers analyzing 13 years of data from NASA’s Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy. “It is a comp…

5 min read NASA Scientists Discover a Novel Galactic ‘Fossil’ Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears to have blasted through the galaxy after its central supermassive black hole erupted some 5 million years ago. Some 5 million years ago, a black hole eruption in the galaxy NGC 4945 set off a star-formation frenzy and shot a vast cloud of gas into intergalactic space. Watch and learn how two X-ray telescopes revealed the story. Credit: NASA’s Goddard Space …

These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies. Clusters of galaxies are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This research, made using Chandra and other telescopes, showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. In these images, X-rays from Chandra are shown along with optical data from Hubble.X-ray: NASA/CXC/MIT/M. Calzadilla el al.; Optical: NASA/ESA/STScI; Image Processing: N…

Satellite imagery shows a portion of East Antarctica on Jan. 9, 2022, before icebergs calved off the Glenzer and Conger glaciers. NISAR will observe nearly all of the planet’s land and ice surfaces twice every 12 days, monitoring Earth’s frozen regions, known as the cryosphere.USGS Much of the Glenzer and Conger glaciers had collapsed by March 23, 2022, spawning numerous icebergs, as shown in this satellite image. NISAR will document such changes around the globe, and its geographic coverage of Antarctica will be the most extensive for a radar satellite mission to date.USGS …

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Nenad Miljkovic University of Illinois at Urbana-Champaign Traditional elastocaloric refrigeration systems are based on uniaxial compression of the elastocaloric material which makes them highly constrained by actuator requirements, the physics of column buckling, and limited surface area for heat transfer. Professor Miljkovic will investigate a novel elastocaloric system based on bending of the elastocaloric material, which removes these constraints. The design requires less energy for equivalent performance and can be run in a continuous loop further increasing efficiency. The team wi…
