NASA may turn to its commercial partner SpaceX to transport three astronauts back to Earth after a Russian Soyuz spacecraft suffered a coolant leak in mid-December.

In a blog post published on Friday, NASA said that it “reached out to SpaceX about its capability to return additional crew members aboard Dragon if needed in an emergency.” At the moment, NASA is investigating whether or not the Soyuz spacecraft would still be capable of carrying astronauts on the trip back from the International Space Station, the space agency added.

NASA published a video from its Artemis I Orion spacecraft, when it saw Earth disappear behind the Moon at the halfway point of its mission.

There is growing concern over China’s Moon ambitions.

The race to the Moon between the United States and China is becoming increasingly fierce, and the next two years could determine who wins. During an interview with Politico.

Three crew members that may be stuck on the International Space Station could have the chance to return home on a SpaceX Dragon, if the option is required, a report suggests.

Hibernation is a state adopted by certain mammals as an adaptation to adverse winter conditions. Typical features of hibernation include greatly reduced metabolic activity and lowered body temperature.

As warm-blooded animals, primates (except lemurs) do not naturally hibernate or even experience torpor. But can we manipulate the body temperature of primates and make them fall into a hypometabolic state or even artificial hibernation?

A research team led by Dr. Wang Hong and Dr. Dai Ji from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences has recently reported the first reliable hypothermia in nonhuman primates caused by activating a group of hypothalamic neurons.

NASA’s recent Artemis I mission has put the spotlight back on lunar exploration, so let’s take a look at the moon missions set for 2023.
