NASA’s StarBurst instrument outside a thermal vacuum chamber at NASA’s Marshall Space Flight Center in Huntsville, Alabama. NASA/Daniel Kocevski Heated, cooled, shaken, and settled – NASA’s StarBurst instrument is several steps closer to being ready for launch. The small satellite is now awaiting instrument calibration following a successful integration in Canada and rigorous testing by engineers at the agency’s Marshall Space Flight Center in Huntsville, Alabama. StarBurst is designed to detect the initial emission of short gamma-ray bursts, some of the most powerful explosions in the universe and a key indicator of neutron star mergers. This would provide valuable insight into such events, which are also detected through gravitational waves by observatories on Earth. These events are where most of the heavy metals in the universe, such as gold and platinum, are formed. To date, only one such event has been observed simultaneously in gravitational waves and gamma-rays; StarBurst _is expected to_ find up to 10 per year. StarBurst arrived at NASA Marshall in March 2025. During its time at the center, the instrument underwent thermal testing in a vacuum chamber and flight vibration testing. The team held StarBurst’s nonstop thermal testing in a vacuum chamber, 24 hours a day for 18 days. Technicians placed radioactive material into the vacuum chamber, giving StarBurst the ability to detect gamma-ray signals during the tests. NASA Marshall test engineers fit test the multi-layer insulation blanket in early August at Marshall’s Stray Light Facility. The thermal blanket will insulate the crystal detector units. NASA/Michael Allen Test teams conducted thermal balance testing to simulate the hottest and coldest situations the instrument will operate under in space. Data from these tests improves thermal models used by NASA engineers, while also ensuring the satellite can handle these temperatures in orbit. NASA engineers also completed a 24-hour “bake-out,” a process that removes unwanted gas or vapor from the instrument using extreme heat in a vacuum. “NASA’s StarBurst mission is ready for its next stage of assembly and is one step closer to flight,” said Daniel Kocevski, principal investigator at NASA Marshall. “Testing at NASA Marshall has verified engineering models, adding our understanding of how StarBurst will operate in space as it observes gamma ray emission from merging neutron stars to help us better understand the building blocks of Earth—and the universe.” Outside of the vacuum chamber, a “vibe test” bolted the instrument to a special “shaker table” to simulate the vibrations and turbulence StarBurst will experience during launch. While at NASA Marshall, StarBurst underwent a series of tests in a vacuum chamber NASA The Marshall team shipped the StarBurst instrument to Space Flight Laboratory at the University of Toronto, which manufactured the spacecraft bus, in August. Prior to shipment, teams at Marshall’s Stray Light Facility fit-tested the multi-layer insulation blanket needed to insulate the crystal detector units from the harsh space environment. StarBurst is equipped with 12 of these detectors, which serve as the main gamma-ray detection system on the spacecraft. Marshall team members traveled to Toronto and were on hand to help integrate the instrument with the spacecraft bus in early September. Testing at Marshall set the stage for planned post-integration testing, which included functional testing and electromagnetic compatibility testing. StarBurst is scheduled to undergo additional calibration, vibration, and thermal vacuum testing in the spring. Integration teams intend to have StarBurst launch-ready by June 2026. NASA plans to launch the satellite as early as 2027 during the next run of the Laser-Interferometer Gravitational Wave Observatory to maximize the chance of detecting gamma-ray bursts that coincide with gravitational wave events. To date, such a joint gamma-ray and gravitational-wave detection has been observed only once. StarBurst was successfully integrated with the spacecraft bus Marshall team members were on hand to help integrate the instrument with the spacecraft bus at the Space Flight Laboratory at the University of Toronto in early September. NASA StarBurst is a collaborative effort led by NASA’s Marshall Space Flight Center, with partnerships with the U.S. Naval Research Laboratory, the University of Alabama Huntsville, the Universities Space Research Association, and the University of Toronto Institute for Aerospace Studies Space Flight Laboratory. StarBurst was selected for development as part of the NASA Astrophysics Pioneers program, which supports lower-cost, smaller hardware missions to conduct compelling astrophysics science.

Study pinpoints the exact two ages at which humans age the most dramatically Getting older is weird. You're trucking along, enjoying your middle-aged life, finally feeling like a real adult, when you look in the mirror one day and gasp. "Where did those _wrinkles_ come from?" "Is that skin on my arm… _crepey_?!?" "Why am I _aching_ like that?" Somewhere in your mid-40s, you start noticing obvious signs of aging that seem to arrive overnight. You assumed it was a gradual process that you just hadn't noticed, but it sure as heck felt like it happened really fast. New research indicates that may very well be the case. A 2024 study from researchers at Stanford tracked thousands of different molecules in people age 25 to 75 and found that people tend to make two big leaps in aging—one around age 44 and another around age 60. These findings indicate that aging can actually happen in bursts. Simpsons Gif y.yarn.co “We’re not just changing gradually over time. There are some really dramatic changes,” said senior study author Michael Snyder, Ph.D., a geneticist and director of the Center for Genomics and Personalized Medicine at Stanford University. “It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that’s true no matter what class of molecules you look at.” The researchers assumed the mid-40s changes would be attributed to menopausal or perimenopausal changes in women influencing the overall numbers, but when they separated the results by sex they saw similar changes in men in their 40s. > @suddenly_susan_ > > The accuracy 🤣 #40s #genxtiktok #womenover40 #relatable "“This suggests that while menopause or perimenopause may contribute to the changes observed in women in their mid-40s, there are likely other, more significant factors influencing these changes in both men and women. Identifying and studying these factors should be a priority for future research,” said study author Xiaotao Shen, PhD, a former Stanford Medicine postdoctoral scholar who now teaches at Nanyang Technological University in Singapore. Aging happens in bursts, scientists find.Canva Photos The study included 108 participants who submitted blood and other samples every few months for several years. The scientists tracked age-related changes in 135,000 different molecules—nearly 250 billion distinct data points—to see how aging occurs. The study may shed light on the reasons for jumps in certain diseases and maladies at certain ages. For the 40-somethings, scientists found significant changes in molecules related to alcohol, caffeine, and lipid metabolism, cardiovascular disease, and skin and muscle. For those in their 60s, changes related to carbohydrate and caffeine metabolism, immune regulation, kidney function, cardiovascular disease, and skin and muscle were found. Research shows the body goes through specific changes in our 40s and 60s.Canva Photos The study authors did note that lifestyle might play a role in some of these changes. For instance, alcohol metabolism may be influenced by people drinking more heavily in their 40s, which tends to be a period of higher stress for many people. However, the researchers added that these bursts of aging in the mid-40s and early 60s indicate that people may want to pay closer attention to their health around those ages and make lifestyle changes that support greater overall health, such as increasing exercise or limiting alcohol. The research team plans to study the drivers of these aging bursts to find out why they happen at these ages, but whatever the reasons, it's nice to know that the seemingly sudden onset of age-related woes isn't just in our imaginations. It's understandable that we worry about aging, as physical signs of aging remind us of our own mortality. We also have all kinds of social messaging that tells us youth is ideal and beautiful and old is bad and ugly, so of course we give aging the side-eye. But none of us can avoid aging altogether, so the more positive and healthy we are in our approach to aging, the better off we'll be, no matter when and to what degree aging hits us. _This story originally appeared last year. It has been updated._
