SpaceX launches more Starlink satellites 12 hours after Crew-10 sent to ISS
March 15 (UPI) -- SpaceX launched another batch of Starlik satellites into orbit Saturday morning, a little more than 12 hours after the private company teamed up with NASA to send four astronauts to the International Space Station -- also from Florida.
In addition, SpaceX sent 74 satellites from Vandenberg Space Force Base on a rideshare mission called Transporter 13 late Friday from California.
All three involved a Falcon 9 rocket.
The SpaceX flight with 23 satellites, including 13 with direct-to-cell capabilities, lifted off at 7:35 a.m. EDT from Cape Canaveral Space Force Station pad 40. Eight minutes later the Falcon 9's upper stage landed aboard drone ship Just Read the Instructions in the Atlantic Ocean, completing its 18th mission.
This was the 23rd SpaceX from Florida this year.
This launch came two days, eight hours, 59 minutes and 40 seconds after the liftoff of the Starlink 12-21 mission, beating SpaceX's previous turnaround time at that pad by nearly six hours.
Earlier Saturday from California, SpaceX launched satellites developed by Cape Canaveral-based Sidus Space at 11:43 p.m. PDT.
"There were 74 payloads on this flight, including cubesats, microsats, hosted payloads, a re-entry capsule, and an orbital transfer vehicle carrying 11 of those payloads to be deployed at a later time," SpaceX reported.
The first Transporter mission launched in January 2021, sent 143 payloads to orbit, a record that still stands.
The rocket's first stage came back to Earth 7.5 minutes later, making a vertical, powered touchdown back at Vandenberg. It was the 13th landing for this booster and the 400th for a Falcon 9 first stage overall, according to SpaceX.
On Saturday light, Crew-10 will dock with the ISS. The Dragon capsule is scheduled to reach the space station about 11:30 p.m. EDT.
The crew members are Commander Anne McClain and pilot Nichole Ayers with NASA, and mission specialists Takuya Onishi of the Japan Aerospace Exploration Agency and Kirill Peskov, a Roscosmos cosmonaut with Russia.
The Falcon 9 lifted off from Kennedy Space Center's pad 39A at 7:03 p.m. under a clear sky and a setting sun. The flight got the go ahead after they resolved an air pocket issue in the hydraulics system for the clamp arm supporting the Falcon 9 rocket. The flight had been scheduled for Wednesday and didn't go off on Thursday because of unfavorable weather conditions along the path.
Minutes after launch, Falcon 9's first stage landed on Landing Zone 1 at Cape Canaveral Space Force Station.
Then, Dragon went into low Earth orbit.
When the spacecraft docks, there will be 11 crew members.
Aboard the Crew-9 capsule, Williams and Wilmore will ride back to Earth "no earlier than Wednesday March 19," according to NASA. They will be joined by NASA's Nick Hague and Roscosmos' Aleksandr Gorbunov, who arrived at the ISS on Sept. 29, 2024.
Suni Williams and Butch Wilmore went to the Space Station on the troubled Boeing Starliner June 5, 2024, for what was planned as a week-long test flight. Due to Starliner issues it became a nine-month mission.
The next SpaceX launch is scheduled for Monday from Cape Canaveral Space Force Station pad 40. The launch window for another batch of Starlink satellites opens at 2:09 p.m.

James Webb Peers Into Mysterious Haze Covering Pluto
Astronomers using the James Webb Space Telescope have peered into a mysterious blue haze cloaking the surface of Pluto — and discovered that it's controlling the dwarf planet's climate and atmosphere. The findings, reported in a new study published in the journal Nature Astronomy, also hint that other worlds, including our own, may have a hazy history as well, potentially reshaping our understanding of how the Earth came to possess its current climate. "This is unique in the solar system," lead author Tanguy Bertrand, an astronomer at the Paris Observatory in France, told Live Science. "It's a new kind of climate, let's say." When NASA's New Horizons mission flew by Pluto in 2015, the space probe revealed that the dwarf planet was far from a "dead" world, instead possessing a complex geography defined by mountains, glaciers, ice sheets, and frozen dunes. Regions even differed in the type of ice they comprised: some were dominated by methane, others nitrogen, and all of it undergirded by a "bedrock" of water ice. In the most blatant violation of Pluto's former reputation as an inert hunk, the aptly-named "volatile" ices on its surface regularly redistributed themselves according to seasonal patterns. One of the most peculiar finds, however, was that Pluto appeared to be leaking copious amounts of its already thin atmosphere into space, noted. Stranger still, some of these discarded gas molecules were being sucked up directly by its outsized moon, Charon, something that's yet to be witnessed elsewhere in the solar system. To explain this bizarre behavior, a 2017 paper led by Xi Zhang, a planetary scientist at the University of California, Santa Cruz who also coauthored this latest study, predicted that Pluto's atmosphere was covered with a cooling haze made of nitrogen and methane. As Live Science explains, the haze intervened by absorbing what little solar radiation reached it during the day — on average, Pluto orbits at a distance 39 times farther away than the Earth is from the Sun — and releasing it back into space at night in the form of infrared energy. At least, that was the theory. Because of how closely Charon, the huge moon, orbited Pluto, the pair's temperature readings were jumbled together. Resolving one from the other was impossible. "Basically, we couldn't know what part of the signal is due to Charon and what part is due to Pluto's haze," Bertrand told Live Science. Enter the James Webb Space Telescope. According to the 2017 study, if the haze behaved as predicted, Pluto should emit strong radiation in the mid-infrared spectrum. Webb, with its state-of-the-art Mid-Infrared Instrument (MIRI), was able to distinguish between Pluto's signals and those of its moon, confirming that the dwarf planet's haze was producing the predicted light emissions. "In planetary science, it's not common to have a hypothesis confirmed so quickly, within just a few years," Zhang said in a statement about the work. "So we feel pretty lucky and very excited." According to Zhang, other worlds in the Solar System, including Neptune's moon Triton and Saturn's moon Titan, possess haze-rich atmospheres similar to Pluto's — "so we need to rethink their roles, too," he said. Even Earth may be due for some serious climate introspection. "Before oxygen built up in Earth's atmosphere, about 2.4 billion years ago, life already existed," Zhang explained. "But back then, Earth's atmosphere was totally different — no oxygen, mostly nitrogen, and a lot of hydrocarbon chemistry." "So by studying Pluto's haze and chemistry," he added, "we might get new insights into the conditions that made early Earth habitable."

Mysterious fast radio bursts help astronomers pinpoint cosmic ‘missing' matter
Sign up for CNN's Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. Astronomers have used mysterious fast radio bursts, or millisecond-long bright flashes of radio waves from space, to help them track down some of the missing matter in the universe. Dark matter and dark energy make up most of the universe. Dark matter is an enigmatic substance that shapes the cosmos, while dark energy is a force that accelerates the expansion rate of the universe, according to NASA. Both are impossible to directly observe but can be detected due to their gravitational effects. But the rest of the universe is made of cosmic baryons, or ordinary matter, which can be found in tiny particles called protons and neutrons. 'If you add up all the stars and planets and cold gas that you see with your telescopes, it only amounts to less than 10% of ordinary matter in the universe,' said Liam Connor, assistant professor of astronomy at Harvard University. While astronomers thought most of the universe's ordinary matter was floating in the spaces between galaxies, called the intergalactic medium, or within the extended halos of galaxies — vast, spherical regions including stars and hot gas — they couldn't measure this foglike matter. That's because ordinary matter emits light at different wavelengths, but much of it is so diffuse that it's like trying to spot fog, astronomers say. The inability to detect roughly half of the cosmos' ordinary matter led to a decades-long cosmology struggle called the missing baryon problem. Now, Connor and his colleagues have directly observed the missing matter by using the flashing of fast radio bursts to essentially map out what couldn't be seen before. They reported their findings in a new study published Monday in the journal Nature Astronomy. 'The FRBs shine through the fog of the intergalactic medium, and by precisely measuring how the light slows down, we can weigh that fog, even when it's too faint to see,' Connor, the paper's lead author, said. Much of the work for the study took place while Connor was a research assistant at the California Institute of Technology. Down the road, astronomers believe they can use fast radio bursts to help illuminate the otherwise invisible structure of the universe. More than a thousand fast radio bursts, or FRBs, have been detected since their discovery in 2007. Only about 100 have been traced back to galaxies, according to the study authors. Astronomers are still unsure of the exact causes behind the bursts, but finding more of them could reveal their murky origins. To illuminate the missing matter, the new analysis relied on a mixture of previously observed fast radio bursts, as well as bright flashes that had never been observed until the research was underway. The 69 fast radio bursts examined in the study exist at distances ranging from 11.74 million to nearly 9.1 billion light-years from Earth. The farthest, named FRB 20230521B, was discovered during the research and is the current record holder for the most distant fast radio burst ever observed. The study team used the Deep Synoptic Array, a network of 110 radio telescopes, to find and identify 39 of the fast radio bursts in the study. The telescope array, designed to trace fast radio bursts back to their origin points, is located near Bishop, California, at Caltech's Owens Valley Radio Observatory. The W. M. Keck Observatory in Hawaii and Palomar Observatory near San Diego helped measure the distances between the fast radio bursts and Earth. And the other 30 fast radio bursts were found by the Australian Square Kilometre Array Pathfinder and other telescopes around the world. When radio waves travel as fast radio bursts toward Earth, their light can be measured in different wavelengths that spread out. How much the light spreads out is dependent on how much matter is in its path. The team was able to measure how much each fast radio burst signal slowed down as it passed through space before reaching Earth, illuminating the gas it encountered along the way. The speed of fast radio bursts can be affected by what they travel through, meaning different wavelengths of light arrive at different times. While long, red wavelengths travel more slowly to reach Earth, shorter, bluer wavelengths arrive more quickly. Each wavelength allowed astronomers to measure the invisible matter. The short pulses of fast radio bursts are crucial for this measurement because they act like flashing cosmic beacons, Connor said. 'We can measure very precisely how much the radio pulse is slowed down at different wavelengths (it's called plasma dispersion), and this effectively counts up all the baryons,' Connor said. 'For a star that shines continuously or a source that is not in the radio, we can not measure this 'dispersion' effect. It must be impulsive, short, and at radio wavelengths.' The team was able to use the dispersion of light to map and measure matter along the pathway of the fast radio bursts. 'It's like we're seeing the shadow of all the baryons, with FRBs as the backlight,' said study coauthor Vikram Ravi, an assistant professor of astronomy at Caltech, in a statement. 'If you see a person in front of you, you can find out a lot about them. But if you just see their shadow, you still know that they're there and roughly how big they are.' After mapping out all the fast radio bursts and the matter they passed through and illuminated, the team determined that 76% of cosmic matter exists as hot, low-density gas in the space between galaxies. Another 15% can be found in galactic halos, while the remainder is located within galaxies themselves as stars, planets or cold gas. The observation-based findings align with prior predictions made using simulations, according to the study authors. William H. Kinney, professor of physics at the University at Buffalo's College of Arts and Sciences, agreed. 'So the upshot is that they came up with a new way of finding the baryons we knew had to be there, but whether they were really in the (intergalactic medium) instead of in halos was still something of an open question,' said Kinney, who was not involved in the research. 'The decades-old 'missing baryon problem' was never about whether the matter existed,' Connor said. 'It was always: Where is it? Now, thanks to FRBs, we know: Three-quarters of it is floating between galaxies in the cosmic web.' Understanding the distribution of ordinary matter can help researchers understand how galaxies grow and evolve. 'Baryons are pulled into galaxies by gravity, but supermassive black holes and exploding stars can blow them back out — like a cosmic thermostat cooling things down if the temperature gets too high,' Connor said. 'Our results show this feedback must be efficient, blasting gas out of galaxies and into the (intergalactic medium).' Fast radio bursts also may be able to help map the cosmic web in detail, Ravi said. This structure, largely made of dark matter, serves as the backbone of the universe, according to NASA. Caltech is currently planning to build another radio telescope in the Nevada desert, which could build upon the findings from the new study by finding and tracing up to 10,000 fast radio bursts per year, Connor said. 'It's a triumph of modern astronomy,' Ravi said.'We're beginning to see the Universe's structure and composition in a whole new light, thanks to FRBs. These brief flashes allow us to trace the otherwise invisible matter that fills the vast spaces between galaxies.'

What students, officials say about VSU appearance as only HBCU in prestigious NASA event
Virginia State University students were the only participants from a Historically Black College or University to compete in the prestigious 2025 NASA Lunabotics Challenge last month, reinforcing VSU's growing reputation in STEM education. From May 20 to 22, 15 students from VSU's College of Engineering and Technology traveled to the Kennedy Space Center in Florida to participate in the rigorous two-semester systems engineering competition. The event challenges collegiate teams to design, build, and operate robotic systems capable of performing complex tasks on simulated lunar terrain, preparing them for the realities of space exploration. Thirty-six additional colleges and universities across the country were also selected to participate in the challenge, according to an October 2024 NASA social media post, including the University of Virginia, New York University, Rutgers University, Purdue University, Liberty University and more. 'VSU is incredibly proud of these students for this remarkable achievement and for representing HBCUs nationwide with distinction,' a press release from the university states. 'Their hard work and dedication elevated the University's standing in advanced engineering disciplines and reaffirmed the University's commitment to offering students transformative opportunities for excellence in engineering and computer science.' The press release adds that the VSU team's robot demonstrated versatility and precision in the Lunatics Challenge, successfully completing all required tasks and activities set by NASA. Dr. Nasser Ghariban, Chair of VSU's Department of Engineering and faculty advisor to the Lunabotics team, praised them for their performance at the event. "The team's perseverance and collaborative spirit throughout this challenging competition reflect their readiness for real-world engineering challenges,' he said in the press release. 'Participating in this competitive NASA event provided invaluable hands-on experience that will significantly benefit their future careers in technology and exploration." "The strong finish by our Lunabotics team emphasizes their remarkable dedication, innovative thinking, and technical prowess,' Dr. Dawit Haile, Dean of the College of Engineering and Technology, added in the press release. 'Their success as the only HBCU team in the competition underscores VSU's commitment to excellence in STEM education." For the students that participated, the experience was invaluable. 'Being part of the NASA Lunabotics 2025 competition was honestly one of the most exciting and demanding experiences I have had here in Virginia State University,' Kwabena E. Amoako, VSU computer engineering student and hardware team lead for the challenge, told The Progress-Index. 'We spent countless late nights in the lab, troubleshooting circuits, swapping out components, debugging code, and rebuilding the robot again and again. It really forced us to grow, not just as engineers, but as a team learning how to solve complex problems under pressure.' Petersburg crowd braves rain, joins others across nation in 'No Kings' anti-Trump protests Amoako added that representing VSU on a national stage became especially meaningful to him on the day of the event, when he realized his team was the only one from an HBCU. 'In that moment, it wasn't just about building a robot anymore. It felt way bigger. We were showing that students from HBCUs can go head-to-head with anyone, anywhere, and hold our own,' he said. 'I felt proud, but also a sense of responsibility. It made me want to give 110%, not just for myself or my team, but for every student out there who might think these kinds of opportunities aren't for them. Because they are.' Christopher Payne, a computer science graduate student at VSU and fellow team member, agreed. "Representing VSU, an HBCU, on a national stage was very important to me," he said. 'Our selection for this competition demonstrated the quality of work and exceptional opportunities that minority-serving institutions continue to produce, further proving the importance of funding and support for our country's HBCUs and minority-serving institutions."
