Soyuz capsule at space station hit by micrometeorite in Dec

[Robert Zwilling]

The Soyuz capsule is leaking coolant at the space station after being hit by a micro particle in December. Due to the its speed, 15,000 miles per hour, and direction, the particle has been determined to not be space junk. The tiny hole is .8 millimeters in diameter and is on the external cooling system of the Soyuz MS-22 capsule.
Russia to launch new Soyuz capsule to replace leaky spacecraft on space station
It is impossible to repair and replace the cooling system so a replacement capsule is being launched Feb 20th, earlier than originally scheduled, to replace the leaking capsule. The cooling system isn't working good enough for people but it can carry equipment back to Earth on the return flight.

That video feed was cool. There is a lot of coolant spraying out of the .8mm puncture. Do you know how much coolant it contains?
And the internal temp of the capsule reaching 104F (40c) during re-entry without the coolant is hot for sure.

I haven't found the coolant specs but there are 2 two external radiator coolant systems, and one of them got punctured.

Interesting, but not fascinating. It is a long way to Mars, & there is only so much they can do to protect against such things. I recall one of those Mars-themed movies of recent years, featured such an element.

The current economic situations might cause the rush to space crusade to look at closer, cheaper to accomplish targets, such as the Moon, instead of Mars.
