SpaceX capsule begins 17-hour descent as Crew-10 astronauts head home after nearly five months in orbit
US astronauts Anne McClain and Nichole Ayers, Japan's Takuya Onishi and Russian cosmonaut Kirill Peskov are expected to spend more than 17 hours in the capsule before splashing down off California's coast today.
Their return will mark the end of the 10th crew rotation mission to the space station under Nasa's Commercial Crew Program, which was created to succeed the Space Shuttle era by partnering with private industry.
The Dragon capsule of billionaire Elon Musk's SpaceX company detached from the International Space Station (ISS) at 2215 GMT on Friday.
The capsule's dizzying drop back down to Earth will be slowed when it re-enters Earth -- and then again by huge parachutes to soften its landing.
After the capsule splashes down, it will be recovered by a SpaceX ship and hoisted aboard.
Only then will the astronauts be able to breathe Earth's air again, for the first time in months.
The astronauts, known as Crew-10, conducted numerous scientific experiments during their time on the space station, including studying plant growth and how cells react to gravity.
Their launch into space in March was heavily scrutinized because it finally allowed two US astronauts -- who had been unexpectedly stuck onboard the space station for nine months -- to return home.
When they launched in June 2024, Butch Wilmore and Suni Williams were only supposed to spend eight days in space on a test of the Boeing Starliner's first crewed flight.
However, the spaceship developed propulsion problems and was deemed unfit to fly back, leaving them stranded in space.
Nasa announced this week that Wilmore has decided to retire after 25 years of service at the US space agency.
Last week, US astronauts Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russian cosmonaut Oleg Platonov boarded the ISS for a six-month mission.

Study attributes 440 ‘excess deaths' to January's Los Angeles wildfires
Additional deaths reflect a mix of factors, from increased exposure to smoke and toxins to healthcare delays and disruptions. (AP pic) LOS ANGELES : Wildfires that devastated parts of the Los Angeles area in January indirectly led to hundreds of deaths in the ensuing weeks, far exceeding the official toll of 31 fatalities, according to a study released on Wednesday. The research, published in the Journal of the American Medical Association, or JAMA, estimated 440 'excess deaths' were attributable to the fires from Jan 5 to Feb 1, using models that compared predicted mortality under normal circumstances to actual numbers documented during that period. The additional deaths likely reflect a mix of factors, including increased exposure of people with heart and lung disease to poor air quality from smoke and toxins released by the fires, as well as healthcare delays and disruptions, the study said. The findings 'underscore the need to complement direct fatalities estimates with alternative methods to quantify the additional mortality burden of wildfires and of climate-related emergencies more broadly,' the researchers wrote. Two wind-driven wildfires that erupted during the first week of January on opposite sides of Los Angeles damaged or destroyed nearly 16,000 structures combined – laying waste to much of the seaside district of Pacific Palisades and the foothill community of Altadena. Together, the blazes scorched 152sq km, an area larger than Paris. The official tally of people who perished as a direct result of the fires stands at 31, after the most recent set of human remains were unearthed in Altadena in July, six months after the fires. Governor Gavin Newsom in February requested nearly US$40 billion in wildfire aid from Congress. Some estimates put economic losses from the fires at more than US$250 billion, making the conflagration one of the most costly natural disasters in US history. The JAMA study acknowledged some limitations, saying the data may need to be revised upward in the future and the research did not reflect any fire-attributable deaths beyond Feb 1.

China rocket shortage means it may have to pick a favoured Starlink challenger
As China scrambles to build massive internet networks in space to rival Starlink, a growing divide is quietly emerging on the ground between national priorities and local ambition. The country appears to be fast-tracking the roll-out of Guo Wang, a state-run 13,000-satellite constellation slated for completion within a decade, tightening control over launch resources and leaving other projects in limbo. Often known as Beijing's answer to SpaceX's Starlink, Guo Wang has launched three batches of satellites in the past week alone – a sharp jump from its earlier pace of about one batch every two months. The launches, which bring the total number of Guo Wang satellites in orbit to 57, used three different Long March rockets, signalling a national push to ensure the project received all the launch capacity it needed to stay on track. Meanwhile, Qianfan, a 15,000-satellite constellation backed by the Shanghai municipal government, has not launched since March, despite already placing 90 satellites in orbit. With state-owned rockets seemingly out of reach, Qianfan is now turning to private rocket companies for help. In late July, Shanghai Yuanxin Satellite Technology – the company behind Qianfan – issued its second launch tender of the year, seeking seven rocket launches to deploy 94 satellites. The contract, worth 1.4 billion yuan (US$186 million), requires all satellites to be delivered into orbit by March next year. One option calls for launching 10 satellites at a time, using a rocket that has already flown and could deliver at least 2.8 tonnes to a 950km (590 miles) near-polar orbit. The leading contender is Beijing-based LandSpace, whose upgraded Zhuque-2E can carry up to 4 tonnes – although to a lower 500km orbit. The second option involves launching 18 satellites at once, requiring a rocket that could deliver at least 4.8 tonnes to an 800km orbit and a firm commitment to complete its first flight by the end of this year. So far, only a few Long March rockets meet that threshold, including the 6A, 8, 8A and 12 that have supported past Guo Wang and Qianfan launches. Among private rockets still in development, LandSpace's reusable, heavy-lift Zhuque-3 appears to be the most promising, with a maiden flight targeted for this autumn. Yuanxin's first tender, issued in February, aimed to deploy 162 satellites across nine launches. But with fewer than three bids submitted, the process was cancelled, according to a statement on the tender result issued later that month. Space observers said the launch mission divide between Guo Wang and Qianfan highlighted a key factor behind China's launch bottleneck: the lack of reusable rockets. Unlike SpaceX's Falcon 9 – which has launched satellites up to two or three times a week – China still relies on expendable launchers that have lower capacity and slower turnaround. Without a comparable reusable system, the country's squeeze on rocket access was expected to persist, leaving ambitious satellite projects fighting for limited launch slots for years to come, the experts warned. - SOUTH CHINA MORNING POST

International crew returns to Earth after 5 months on space station
WASHINGTON: An international crew of four astronauts has returned to Earth after nearly five months aboard the International Space Station. The SpaceX capsule carrying US astronauts Anne McClain and Nichole Ayers, Japan's Takuya Onishi, and Russian cosmonaut Kirill Peskov splashed down off California's coast. Their safe return concludes NASA's 10th crew rotation mission under the Commercial Crew Program. The Dragon capsule, operated by Elon Musk's SpaceX, detached from the ISS on Friday before re-entering Earth's atmosphere. NASA confirmed the capsule endured extreme heat of up to 3,500 degrees Fahrenheit during re-entry. Parachutes slowed the spacecraft from 17,500 miles per hour to just 16 miles per hour before splashdown. A recovery ship retrieved the capsule, allowing the astronauts to breathe Earth's air for the first time in months. The crew will now travel to Houston to reunite with their families. During their mission, they conducted experiments on plant growth, cell reactions to gravity, and microgravity's effects on human eyes. NASA acting administrator Sean Duffy praised the mission as a step toward long-duration space exploration. Anne McClain described her farewell to the ISS as bittersweet, acknowledging the global collaboration behind space missions. NASA recently announced workforce cuts affecting 3,900 employees under federal budget reductions. The agency continues prioritising crewed missions to the Moon and Mars. The Crew-10 mission also facilitated the return of two astronauts unexpectedly stranded on the ISS for nine months. Boeing's Starliner spacecraft, initially meant for an eight-day test flight, encountered propulsion issues, delaying their return. NASA confirmed astronaut Butch Wilmore's retirement after 25 years of service. A new crew, including US, Japanese, and Russian astronauts, recently began a six-month mission aboard the ISS. - AFP
