- Micrometeorite that hit radiotor and pipe leading to it.
- Russia made tests on ground to reproduce the type of damage seen, and particle of about 1mm in diametre, and 7km per second speed.

Space debris in same/similar orbit could not hit the Soyuz with such a
high velocity (otherwise would have been in much higher orbit).

-Soyuz remains escape pod, but initial procedures is to fic problem on
Station to avoid needing evacuation. And currently working to perhaps
moving 1 or 2 of the Soyuz crew members to Dragon. Reducing persons from
Soyuz would reduce heat load during an emergency landing.

-Russia will send next Soyuz empty end of February instead of Mid marhc,
and extend current crew by a number of months until next crew can come
up in September. (or earlier depending on when it become ready).

-new Soyuz arrives before old one leaves so transfer of seat liners etc
easier and crew not left without escape pod in between.

In the event of need for emergency egress, it would be an emergency
landing, instead of a nominal 6 hour return to earth to reduce time
exposed to heat above mission rules.

Predictions would be in high 30 and low 40° celcius and they are more concerned about humidity.

SpaceX on loading more crewmembers: looking at options of adding 1 crewmembers, and would imvolved moving some stuff from the Soyuz to the
Dragon (seat liner not mentioned, but "strap that in" was mentioned, and
this would be at expense of returning cargo. No mention of how long it
would take to setup the Dragon for this (aka: set it up in advance of an emergency, or only when emergency egress is decided (which woudln't
leave much time to setup if the emergency is such that you need to leave
ASAP)

Russia looking at possibility of having 2 separate cooling loops so if
one fails, the other remains functional. Currently have redundant pumps,
but both on same loop. Krikalev says it is easier said than done based
on the current design. ( consider how 2 separate loops could cool a component).

NASA: we are learning for this incident and may look to strenghten our
vehicles because they too havce radiators that are exposed to debris.

Question: Say you had a scuba tank filled with liquid nitrogen and
attached to urine dump to space. Would venting nitrogen make the scuba
tank cold enough (and condensate extra humidity) to paliate loss of
radiator? or not even close? I take it that during orbital nighttime,
cooling is not necessary?

Could a water tank in the cabin but attached to vacuum provided cooling
since water boils at roughly room temperature when in vacuum?
