Less than that I think, and I’d suspect NASA would do load calculations in metric.

According to this reputable (first result on Google) High School Science Fair Project ^PDF, the average tampon is about 1g. I wouldn’t be surprised if they just budgeted 100g for it.

There's also the point that they don't go bad. It might be easier to send a load up now, that try and fit enough for each female astronaut into every flight.

Agree in general. The problem would be debris trapping, fluid compartmenting, sterility, etc.

But if you need a dressing and that's all you have, unpacking them into gauze pad like things would be great.

All of this assuming you are literally flying 7.5km/s towards a trauma center

Can the same be said about doing that in zero gravity with specialised sensitive equipment all around you that are essentially keeping you alive?

I'll take an infection over crashing down in the ISS any day.

Your bladder changes volume to hold urine; there's no floating, just pressure. Gravity affects that pressure though.

Doubled the bandaids to save weight. I can see why the tampon thing was a struggle for them.

they cut the number of band-aids in the lunar lander's first aid kit from 6 to 12 to save weight.

I see here is the problem. The guy doesn't know how to reduce weight, you don't add more stuff to cut on weight. That explains the extra tampons.

That decision was made on a different level, though, and was largely political.

Every policy is written in blood.

I thought you were going to say adjust their tampon supply estimates and then something about mankind and hell in a cell...
