Ground teams on Florida's Space Coast hoisted Boeing's Starliner spacecraft atop its United Launch Alliance Atlas V rocket this week, putting all the pieces in place for liftoff next month with two veteran NASA astronauts on a test flight to the International Space Station.
This will be the first time astronauts fly on Boeing's Starliner crew capsule, following two test flights without crew members in 2019 and 2022. The Starliner Crew Flight Test (CFT) next month will wrap up a decade and a half of development and, if all goes well, will pave the way for operational Starliner missions to ferry crews to and from the space station.
Starliner is running years behind schedule and over budget. SpaceX's Crew Dragon spacecraft has flown all of NASA's crew rotation missions to the station since its first astronaut flight in 2020. But NASA wants to get Boeing's spacecraft up and running to have a backup to SpaceX. It would then alternate between Starliner and Crew Dragon for six-month expeditions to the station beginning next year.

Sweden is the newest nation to sign onto NASA's Artemis Accords -- a series of non-binding bilateral arrangements for peaceful and responsible exploration. Space.com reports: During a signing event in Stockholm on Tuesday (April 16), Swedish Minister for Education Mats Persson penned the agreement alongside U.S. Ambassador Erik D. Ramanathan. "By joining the Artemis Accords, Sweden strengthens its strategic space partnership with the U.S. on space covering areas such as Swedish space research and the space industry, which in turn also strengthens Sweden's total defense capability," Persson said in a NASA statement. The event in Stockholm comes just on the heels of Switzerland's signing of the Artemis Accords the day before. Greece and Uruguay were also included in February. Sweden is now the 38th nation to join the accords, which were established in 2020, as the first Artemis moon launch inched closer to reality. The Accords mirror principles set out in 1967, as part of the Outer Space Treaty to help govern international cooperation space. NASA is using the refreshed agreement as a guideline for the Artemis program, which aims to send astronauts back to the moon for the first time since Apollo 17, in 1972. In the agency's statement, NASA administrator Bill Nelson welcomed Sweden to the expanding space club. "Our nations have worked together to discover new secrets in our solar system, and now, we welcome you to a global coalition that is committed to exploring the heavens openly, transparently, responsibly, and in peace," Nelson said, adding, "the United States and Sweden share the same bedrock principles, and we're excited to expand these principles to the cosmos."

Florida man tells Ars about his encounter with something that fell from space
news.movim.eu / ArsTechnica · Wednesday, 17 April - 14:09
NASA has confirmed that the object that fell into a Florida home last month was part of a battery pack released from the International Space Station.
This extraordinary incident opens a new frontier in space law. NASA, the homeowner, and attorneys are navigating little-used legal codes and intergovernmental agreements to determine who should pay for the damages.
Alejandro Otero, owner of the Naples, Florida, home struck by the debris, told Ars he is fairly certain the object came from the space station, even before NASA's confirmation. The circumstances strongly suggested that was the case. The cylindrical piece of metal tore through his roof March 8, a few minutes after the time US Space Command reported the reentry of a space station cargo pallet and nine decommissioned batteries over the Gulf of Mexico on a trajectory heading forward the coast of southwest Florida.

NASA has confirmed that a piece of metal that tore through a Florida home last month was space junk from the International Space Station. NBC News reports: The agency confirmed Monday that the 1.6-pound object was debris from a cargo pallet that had been intentionally released from the space station three years ago. The pallet, packed with aging batteries, was supposed to burn up harmlessly in Earth's atmosphere, but a piece survived -- the piece that smashed into a house in Naples, Florida, on March 8. WINK News, a CBS News affiliate in southwestern Florida, first reported the incident. Naples resident Alejandro Otero told the outlet that the object crashed through the roof and two floors of his home. Otero was not home at the time, he told WINK News, but the metal object nearly hit his son, who was two rooms away. In a blog post about the incident, NASA said it had analyzed the object at the Kennedy Space Center in Florida and confirmed that it was part of the equipment used to mount the batteries on the cargo pallet. The piece of space junk is roughly cylindrical in shape and is about 4-inches tall and 1.6-inches wide. NASA said agency staff studied the object's features and metal composition and matched it to the hardware that had been jettisoned from the space station in 2021. At that time, new lithium-ion batteries had recently been installed at the space station, so the old nickel hydrogen batteries were packed up for disposal. The space station's robotic arm released the 5,800-pound cargo pallet containing the batteries over the Pacific Ocean, as the outpost orbited 260 miles above the Earth's surface, according to NASA. NASA said it will perform a detailed investigation of the latest debris incident to determine how the object withstood the extreme trip through the atmosphere.

NASA says it needs better ideas on how to return samples from Mars

NASA's $11 billion plan to robotically bring rock samples from Mars back to Earth is too expensive and will take too long, the agency's administrator said Monday, so officials are tasking government and private sector engineers to come up with a better plan.
The agency's decision on how to move forward with the Mars Sample Return (MSR) program follows an independent review last year that found ballooning costs and delays threatened the mission's viability. The effort would likely cost NASA between $8 billion and $11 billion, and the launch would be delayed at least two years until 2030, with samples getting back to Earth a few years later, the review board concluded .
But that's not the whole story. Like all federal agencies, NASA faces new spending restrictions imposed by the Fiscal Responsibility Act, a bipartisan budget deal struck last year between the White House and congressional Republicans. With these new budget headwinds, NASA officials determined the agency's plan for Mars Sample Return would not get specimens from the red planet back to Earth until 2040.
