As inter-satellite laser links help fuel the rapid expansion of the largest constellations the world has ever seen, a traditional satellite operator wants to put stronger lasers to work clearing the debris that LEO megaconstellations risk leaving behind. Sky Perfect JSAT, Japan’s flagship geostationary satellite operator, announced the creation of a startup in January that

A hydrogel disc can increase 100 times in area when stretched Lili Chen et al. A hydrogel that can stretch to around 15 times its initial length is one of the most elastic materials yet known and could be used for robotic grippers or tendons. Hydrogels, which are made of long chain-like polymer molecules linked

WASHINGTON — A NASA official says he is optimistic that a problem with the Voyager 1 spacecraft that has kept it from transmitting intelligible data for months can be resolved. Speaking at a March 20 meeting of the National Academies’ Committee on Solar and Space Physics, Joseph Westlake, director of NASA’s heliophysics division, said it
Antibodies are proteins that can target and attack certain cells MirrorImages/Alamy An experimental treatment rejuvenates the immune system of older mice, improving the animals’ ability to fight infections. If it works in humans, the therapy could reverse age-related declines in immunity that leave older adults susceptible to disease. These declines may be due to changes

Beer brewers generate a huge variety of flavours from just a handful of ingredients Kutredrig/Getty Images An artificial intelligence that can predict how a beer will taste from its chemical make-up could help create alcohol-free versions that taste just like regular ones. Predicting flavour from chemical compounds is difficult, as complex interactions between ingredients and

WASHINGTON — Several companies that launched their first spacecraft on a rideshare mission earlier this month are reporting varying degrees of success, from full operations to an early end of testing. Apex, a satellite manufacturer that launches its first Aries spacecraft on SpaceX’s Transporter-10 mission March 4, announced March 25 that the satellite has commissioned
Increased exposure to wildfire smoke is one of the most damaging effects of climate change Nasa's Earth Observatory Exposure to rising levels of wildfire smoke could lead to more than 10,000 additional deaths each year in the US by 2050. This could make deaths due to wildfire smoke the costliest consequence of climate change for

The last time Patricia Cooper attended a meeting of the American Astronomical Society, she wasn’t sure what she was getting into. It was January 2020 and Cooper, at the time a vice president at SpaceX, had agreed to represent the company on a panel discussion at the conference on the interference satellite constellations could create
International trade may have helped medieval elites acquire the best horses for jousting tournaments PRISMA ARCHIVO / Alamy Horses owned by the elite in medieval England were probably imported from continental Europe, possibly travelling hundreds of kilometres, according to tooth analysis of horses unearthed at a cemetery in London. In the 1990s, commercial excavators stumbled

WASHINGTON — A Soyuz spacecraft is en route to the International Space Station, two days after a rare last-minute launch scrub. A Soyuz-2.1a rocket lifted off from the Baikonur Cosmodrome at 8:36 a.m. Eastern March 23. It placed the Soyuz MS-25 spacecraft into orbit about nine minutes later. Soyuz MS-25 is commanded by Roscosmos cosmonaut
