NASA launches observatories to study cosmic origins, Sun
The observatories launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on Tuesday, during what appeared to be a picture-perfect launch.
NASA says onboard the rocket was the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer observatory or what is known as the SPHEREx and four small satellites that form the Polarimeter to Unify the Corona and Heliosphere or what is known as the PUNCH for short.
While the goals of each mission are different, the space agency says they are interconnected, as both missions aim to deepen our understanding of the universe.
"Everything in NASA science is interconnected, and sending both SPHEREx and PUNCH up on a single rocket doubles the opportunities to do incredible science in space," Nicky Fox, an associate administrator at NASA Headquarters in Washington, D.C., said in a statement. "Congratulations to both mission teams as they explore the cosmos from far-out galaxies to our neighborhood star. I am excited to see the data returned in the years to come."

Despite challenges leading up to the launch, NASA's Jet Propulsion Laboratory in Southern California announced that it had successfully established communication with SPHEREx, which will soon begin its two-year mission to survey space for light invisible to the human eye.
Astronomers will use the mission to gather data on millions of galaxies, as well as more than 100 million stars in our own Milky Way.
Scientists hope the data will help determine how the universe has evolved and whether the ingredients for life are relatively common throughout the galaxy.
"The fact our amazing SPHEREx team kept this mission on track even as the Southern California wildfires swept through our community is a testament to their remarkable commitment to deepening humanity's understanding of our universe," Laurie Leshin, director, NASA JPL, said in our statement. "We now eagerly await the scientific breakthroughs from SPHEREx's all-sky survey — including insights into how the universe began and where the ingredients of life reside."
The PUNCH satellites also successfully separated from the rocket and are reportedly in good shape – they recently began their commissioning phase before getting to work.
According to NASA, the instruments will work together to create 3D renderings of the Sun's corona and explore solar wind and other space weather events that impact Earth.

"Questions like 'How did we get here?' and 'Are we alone?' have been asked by humans for all of history," James Fanson, a project manager at SPHEREx, stated. "I think it's incredible that we are alive at a time when we have the scientific tools to actually start to answer them."
NASA was able to defray some of the costs by launching the missions on the same rocket and hopes that the observatories last well beyond their intended lifespans.Original article source: NASA launches observatories to study cosmic origins, Sun

International crew bound for space station
NASA and SpaceX launched a four-member crew to the International Space Station (ISS) on Friday for the latest research expedition to the orbiting laboratory. American astronauts Zena Cardman and Mike Fincke, Japan's Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov lifted off at 11:43 am aboard a SpaceX Crew Dragon capsule mounted on a Falcon 9 rocket from Kennedy Space Center in Florida. The capsule, named Endeavour, has previously flown four NASA missions as well as a private mission. The Crew-11 mission marks the 11th crew rotation mission to the ISS under NASA's Commercial Crew Program, which was created to succeed the Space Shuttle era by partnering with private industry. As part of their six-month stay, the Crew-11 astronauts will simulate Moon landing scenarios that could be encountered near the lunar South Pole under the United States-led Artemis program. Using handheld controllers and multiple display screens, they will test how shifts in gravity affect astronauts' ability to pilot spacecraft, including future lunar landers. Continuously inhabited since 2000, the ISS functions as a vital testbed for research that supports deeper space exploration -- including eventual missions to Mars. Among Crew-11's more colorful cargo items are Armenian pomegranate seeds, which will be compared to a control batch kept on Earth to study how microgravity influences crop growth. The ISS is set to be de-commissioned after 2030, with its orbit gradually lowered until it breaks up in the atmosphere over a remote part of the Pacific Ocean called Point Nemo, a spacecraft graveyard. Dmitry Bakanov, the head of Russia's space agency Roscosmos has been holding talks with NASA's acting administrator Sean Duffy this week about the station's future. When US-Russia relations nosedived at the start of the Ukraine war, Russia threatened to pull out of ISS cooperation early. But on Thursday, Bakanov confirmed Russia remained committed to de-orbiting in 2030. ia/wd

Astronauts launch to the space station after sidelined by Boeing's troubled Starliner
Astronauts sidelined for the past year by Boeing's Starliner trouble blasted off to the International Space Station on Friday, getting a lift from SpaceX. The U.S.-Japanese-Russian crew of four rocketed from NASA's Kennedy Space Center. They'll replace colleagues who launched to the space station in March as fill-ins for NASA's two stuck astronauts. Their SpaceX capsule should reach the orbiting lab this weekend and stay for at least six months. Zena Cardman, a biologist and polar explorer who should have launched last year, was yanked along with another NASA crewmate to make room for Starliner's star-crossed test pilots. The botched Starliner demo forced Butch Wilmore and Suni Williams to switch to SpaceX to get back from the space station more than nine months after departing on what should have been a weeklong trip. Ensuring their safe return "meant stepping aside," Cardman said before her launch. "Every astronaut wants to be in space. None of us want to stay on the ground, but it's not about me," said Cardman, the flight commander. Even after launch, "things can change at the last minute, so I'll count myself very fortunate when the hatch opens" to the space station. NASA's Mike Fincke — Cardman's co-pilot — was the backup for Wilmore and Williams on Starliner, making those three still the only ones certified to fly it. Fincke and Japan's Kimiya Yui, former military officers with previous spaceflight experience, were training for Starliner's second astronaut mission. With Starliner grounded until 2026, NASA switched the two to the latest SpaceX flight. Rounding out the crew is Russia's Oleg Platonov. The former fighter pilot was pulled a few years ago from the Russian Soyuz flight lineup because of an undisclosed health issue that he said has since been resolved. On hand for the first launch attempt on Thursday, NASA's new acting administrator, Transportation Secretary Sean Duffy, met with Roscosmos director general Dmitry Bakanov, an invited guest. The two discussed future collaboration, then left town after thick clouds forced a last-minute delay. "What we learn on these missions is what's going to get us to the moon and then from the moon to Mars, which is I think the direction that NASA has to be," Duffy said in a NASA interview. "There's critical real estate on the moon. We want to claim that real estate for ourselves and our partners." To save money in light of tight budgets, NASA is looking to increase its space station stays from six months to eight months, a move already adopted by Russia's space agency. SpaceX is close to certifying its Dragon capsules for longer flights, which means the newly launched crew could be up there until April. NASA is also considering smaller crews — three astronauts launching on SpaceX instead of the typical four — to cut costs. As for Starliner, NASA is leaning toward launching the next one with cargo before flying another crew. Engineers are still investigating the thruster failures and helium leaks that bedeviled Starliner following liftoff. Time is running out as NASA looks to abandon the aging space station by 2030. An air leak on the Russian side of the station remains unresolved after years of patching. "I am not in the least worried" about the leak, which is localized, Platonov said earlier this month.
