AP News reports, “It’s an unprecedented space streak: 25 years of people living off-planet without even a moment’s pause. The International Space Station marks a quarter-century of continuous occupancy this weekend, boasting a guest list of nearly 300 — mostly professional astronauts but also the occasional space touristand movie director. The first full-time residents opened the hatch on Nov. 2, 2000.”

The Washington Post reports, “NASA said Thursday it was postponing a launch of private astronauts to the International Space Station while it works with its Russian counterparts to investigate persistent leaks on the orbiting laboratory. In a statement, NASA said that Russian cosmonauts recently sealed ‘some areas of interest’ in a module on the Russia side of the space station. As a result, ‘the segment is holding pressure,’ NASA said. It added that crews also noticed a ‘new pressure signature,’ and need additional time ‘to evaluate the situation and determine whether any additional troubleshooting is necessary.’”

SPACE reports, “Spacecraft powered by electric propulsion could soon be better protected against their own exhaust, thanks to new supercomputer simulations. Electric propulsion is a more efficient alternative to traditional chemical rockets, and it’s being increasingly used on space missions, starting off with prototypes on NASA’s Deep Space 1 and the European Space Agency’s SMART-1 in 1998 and 2003, respectively, and subsequently finding use on flagship science missions such as NASA’s Dawn and Psyche missions to the asteroid belt. There are even plans to use electric propulsion on NASA’s Lunar Gateway space station.”

Space News reports, “NASA and Roscosmos continue to disagree on the cause and severity of an air leak in the Russian segment of the International Space Station, one that NASA worries could lead to a “catastrophic failure” of part of a Russian module. That disagreement was brought to light during a brief meeting of NASA’s ISS Advisory Committee Nov. 13, which recounted a meeting of that committee with its Roscosmos counterpart in Moscow in September to discuss issues with the station.”
