Technicians move NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility to accommodate installation of its five-panel solar array at the agency’s Kennedy Space Center in Florida on Thursday, Aug. 1, 2024. After moving the spacecraft, the team had to precisely align the spacecraft in preparation for the installation. The huge arrays – spanning more than 100 feet when fully deployed, or about the length of a basketball court – will collect sunlight to power the spacecraft as it flies multiple times around Jupiter’s icy moon, Europa, conducting science investigations to determine its potential to support life. NASA/Frank Michaux View the full a…

New experiments aboard NASA’s Northrop Grumman 21st cargo resupply mission aim to pioneer scientific discoveries in microgravity on the International Space Station. Northrop Grumman’s Cygnus spacecraft, filled with nearly 8,500 pounds of supplies, launched Aug. 3 atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Biological and physical investigations aboard the spacecraft included experiments studying the impacts of microgravity on plants (grass), how packed bed reactors could improve water purification both in space and on Earth, and observations on new rounds of samples that will allow scientists to learn more…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) As chief of test operations at NASA’s Stennis Space Center, Maury Vander has been involved in some long-duration propulsion hot fires – but he still struggles to describe a pair of 34-minute space shuttle main engine tests conducted onsite in August 1988. “When you stop and think about it, …” Vander begins, then pauses. “In 34 minutes, I can leave work and drive home to Slidell (15-20 miles west in Louisiana) and be relaxing in my recliner in that amount of time.” Vander’s struggle is understandable when one considers the numbers. On Aug. 3 and Aug. 15, operators at the Thad Cochran …

To enable deep space missions, the capability to transfer and store cryogenic fuels (typically liquid hydrogen, methane, and oxygen) without significant leakage over long duration missions is critical. NASA has been actively developing zero boil-off cryocooler technology to reduce storage losses. Another source of fuel loss is from leakage at the fuel disconnect used for in-space refueling. Current designs use fluoroelastomer seals which are excellent for applications such as natural gas but are susceptible to embrittlement at the lower temperatures required for liquid hydrogen. In addition, the high contact forces needed to reduce leakage can cause cracking of the seals.…

NASA/Kim Shiflett Teams transport NASA’s SLS (Space Launch System) core stage into the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida on July 24, 2024. Tugboats and towing vessels moved the Pegasus barge and 212-foot-long core stage 900-miles to the Florida spaceport from NASA’s Michoud Assembly Facility in New Orleans, where it was manufactured and assembled. In the coming months, teams will integrate the rocket core stage atop the mobile launcher with the additional Artemis II flight hardware, including the twin solid rocket boosters, launch vehicle stage adapter, and the Orion spacecraft. The Artemis II test flight will be NASA’s fi…

Each Aug. 4, Coast Guard Day commemorates the founding on Aug. 4, 1790, of the U.S. Coast Guard as the Revenue-Marine by Secretary of the Treasury Alexander Hamilton. Although considered an internal event for active duty and reserve Coast Guard members, we take the opportunity of Coast Guard Day to honor the astronauts who began their careers in the Coast Guard. To date, NASA has selected three astronauts who served in the Coast Guard: Bruce E. Melnick in 1987, Daniel C. Burbank in 1996, and Andre Douglas in 2021. While Melnick and Burbank have retired from NASA, the decades long relationship between the agency and the Coast Guard carries on with Douglas. Left: Coas…

5 min read NASA Scientists on Why We Might Not Spot Solar Panel Technosignatures One of NASA’s key priorities is understanding the potential for life elsewhere in the universe. NASA has not found any credible evidence of extraterrestrial life — but NASA is exploring the solar system and beyond to help us answer fundamental questions, including whether we are alone in the universe. For those who study the potential for life beyond Earth, one of the questions has long been trying to determine the likelihood of microbial life versus complex life versus a civilization so advanced that we can spot signs of it, called technosignatures, from here at home. Studying the answe…

“When I was around 16 or 17, I came across this book by Arthur C. Clarke called Space Odyssey 2001. That was actually the first science fiction book that I’ve ever read. I was just so captured by what he had written because the things that he wrote about weren’t [happening] in the far-off future, but in the year 2001. In the book, he talks about a lot about space stations, and space shuttles that go up to the space station, and vehicles that go to the Moon or the Moon base, and all that. I mean, these are terms that you hear now all the time, right? And Arthur C. Clarke actually envisioned it at that time. So that was interesting to me. I hoped that someday I could work o…

2 min read Hubble Spies a Diminutive Galaxy This NASA/ESA Hubble Space Telescope image reveals the dwarf elliptical galaxy named IC 3430. This NASA/ESA Hubble Space Telescope image reveals the subtle glow of the galaxy named IC 3430, located 45 million light-years from Earth in the constellation Virgo. This dwarf elliptical galaxy is part of the Virgo cluster, a rich collection of galaxies both large and small, many of which are very similar in type to this diminutive galaxy. Like its larger elliptical cousins, IC 3430 has a smooth, oval shape lacking any recognizable features like arms or bars, and is missing much of the gas needed to form many new stars. Int…

NASA/Michala Garrison, USGS Landsat 9’s Operational Land Imager-2 captured this image of the open pits and ponds of Telfer Mine and the surrounding rust-colored soil on Dec. 15, 2023. The soils have a reddish tint from the iron oxides that have accumulated from millions of years of weathering. This part of Western Australia is known for being rich in natural resources, including petroleum, iron ore, copper, and certain precious metals. Beneath the soils, veins of gold and silver run through sedimentary rocks, such as quartz sandstone and siltstone, that formed about 600 million years ago, when much of Australia was under water.
