[FPSPACE] One Third of U.S. Astronauts Injured During Soyuz Landings

Although NASA will not be buying any more Soyuz seats, apparently there will
be some sort of barter arrangement with the Russians. A cosmonaut will fly
on the U.S. commercial craft, and an American will be broughtup in a Soyuz.
If Russians flew only on the Soyuz spacecraft, and Americans on the
commercial craft, an unplanned departure by either (for medical reasons,
say) could leave the ISS with one segment unmanned.something that neither
side wants. By mixing crews on spacecraft, they would guarantee that a
departing ship would not leave the Russian or US segment unmanned.

NASA has indicated that it plans to buy no further Soyuz seats - even if it
means, apparently, not staffing ISS with American astronauts for a while
(however long Com Crew needs to get its act together - 3-4 yrs?). The
current buy would run through 2018, when Com Crew is supposed to be flying
reliably, but it was supposed to be flying in 2015. This sort of information
seems to have been released to provide some justification for the decision
to abandon Soyuz and, potentially, temporarily abandon ISS.


The 37.5% figure seems high based on everything I've read and heard. I
wonder what qualifies as an injury - a bruise? Nausea? The wording is vague.

"More injuries have been occurring on Soyuz landings than anticipated. Most
injuries are minor in nature, but are unexpected due to the low energetics
of the landing. This may be an indication that Soyuz landings are harder
than previously thought, or that spaceflight deconditioning reduces human
tolerance to impacts, or a combination of both. ... 37.5% of US crew members
experienced an injury."
