    The risk of space debris falling to Earth and causing deaths and is growing, experts say (opens the original)

    Excerpt · English

    Read excerpt

    Today's scenery in space is not a pretty picture. With the rate at which orbital launches are now occurring, some Earth orbits are so crowded and carry so many potentially dangerous, high-velocity pieces of defunct satellite litter and spent rocket stages that they could jeopardize humanity's future in space. That's the output from experts at the European Space Agency (ESA), waving a number of cautionary flags in its new Space Environment Report 2026. In brief, this disquieting appraisal from ES

    The future of spacecraft windows: 'We can't just live in a box' (opens the original)

    Excerpt · English

    Read excerpt

    No need for a quick spray of Windex to get a clear view of this situation. There's a growing need for windows for rubbernecking space travelers, whether they're making suborbital hops, staying in Earth orbit or conducting far-flung sojourns to the moon and beyond. Retrofire back decades ago when the first Mercury space capsule offered a tiny porthole for its single seat occupant, Alan Shepard. Similarly, the first human in space, cosmonaut Yuri Gagarin, had but a small window to take in the view

    Read excerpt

    China is making progress on its Tianwen 3 Mars sample return mission, which aims to bring back to Earth roughly 500 grams (17.6 ounces) of Red Planet collectibles in 2031. According to the China National Space Administration, the Tianwen 3 mission will have a lander, an ascender, a service capsule, an orbiter and an Earth reentry module. If all goes to plan, Tianwen 3 will launch in 2028 on two Long March 5 heavy-lift rockets from the Wenchang Space Launch Site on the island of Hainan, China's s

    The future of Earth observation: Private satellites and AI bring benefits but also pose risks (opens the original)

    Excerpt · English

    Read excerpt

    We are a planet-based species: With a few notable (astronaut) exceptions, everyone who has ever lived remained glued to our spinning Earth, which now houses 8.3 billion people. That's the gravity of the situation. But we're also a world of floods, typhoons, earthquakes, heat and cold calamities, volcanic eruptions and even encounters with sun-caused auroras and bruises from incoming asteroids. It's quite a world worth watching — and for decades that's what spacecraft have been doing. But what do

    Rocket issues delay 1st-ever private mission to Venus: 'We are awaiting Neutron readiness' (opens the original)

    Excerpt · English

    Read excerpt

    The future of a privately backed robotic mission Venus seems about as cloudy as the planet itself at the moment. Scientists based at the Massachusetts Institute of Technology (MIT) are working with the California-based company Rocket Lab to search for possible signs of life on Venus. The first step in that program is the Rocket Lab Mission to Venus, which will deploy a small, nose cone-like probe crafted to sample the Venusian atmosphere using a device called an autofluorescence nephelometer (AF
