A little while ago, SpaceX’s Crew Dragon Freedom spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center in its Crew-12 or SpaceX Crew-12 mission. After almost exactly ten minutes, it successfully separated from the rocket’s last stage and went en route to carry out its mission. This is the 12th crewed mission of the Crew Dragon spacecraft within the normal rotation of the International Space Station crew.

Yesterday, the Chinese Menghzou spacecraft, launched on the Long March 10 rocket’s first stage from the Wenchang launch site, completed a suborbital flight test. The rocket conducted its own test, lasting nearly 8 minutes, with a controlled splashdown, as part of the development of a reusable launch system. At the end of the test, the Menghzou splashed down as well, but in its case, it was also recovered, as the capsule is designed to carry taikonauts and is also reusable. These were important tests because their success represents a step forward toward Chinese crewed Moon missions.

An article accepted for publication in the “Open Journal of Astrophysics” reports evidence that the galaxy MoM-z14 is the most distant known so far. A team of researchers led by the Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology (MIT) used the James Webb Space Telescope as part of the “Mirage or Miracle” (MoM) survey, in which the NIRSpec instrument was used to verify the nature of very bright and potentially very distant galaxies observed in images captured by the NIRCam instrument. The results confirm that we see MoM-z14 as it was about 280 million years after the Big Bang, confirming again that highly active galaxies existed at that time.

An article published in “The Astrophysical Journal” reports the results of a study on the habitable zone that goes beyond the so-called conservative zone because it’s based on rigid assumptions. Astrophysicist Amri Wandel of the Hebrew University of Jerusalem focused on examining the conditions existing in systems of low-mass stars: orange dwarfs (K-class stars) and red dwarfs (M-class stars). The study specifically considered planets tidally locked to their stars.

Amri Wandel conducted an analysis using climate models that account for global heat transport, the greenhouse effect, and albedo. This led him to conclude that these stars may host planets potentially habitable for Earth-like life forms orbiting outside the conservative habitable zone.

A few hours ago, the Shenzhou 20 spacecraft landed after spending 270 days docked at the Chinese Tiangong space station, where it arrived on April 24, 2025, carrying three taikonauts: Chen Dong, Chen Zhongrui, and Wang Jie. The Shenzhou 20 departed the station about nine hours earlier and landed at a site called Dongfeng in China’s Inner Mongolia Autonomous Region. The three taikonauts returned to Earth on November 14, 2025, aboard the Shenzhou 21 spacecraft because the Shenzhou 20 suffered small fractures to a window following the impact of what was likely space debris and was deemed unsafe for human transport. Despite this, the preliminary inspection showed that the Shenzhou 20 is generally in good condition.
