> Cupola windows got hit by debris a couple times, so now they are kept closed when not in use

You'd think that opening the windows in space was a bad idea anytime.

Thanks, I thought it was an unusual colloquialism for "couple of"

I find it funny that someone wrote bulletproof in the specifications of the windows. Is the bulletproof term used in the space industry?

The funny part is that what they actually need is much stronger than merely "bulletproof," if only it had been invented.

"spaceproof" would sound much cooler, to be honest.

"Earthlings thrash proof" would be more accurate.

Did you mean to say trash?

Yes..yes i did ;)

Meteorite proof?

Bullet proof is a little open ended for a spec.

Meteor may be a tad vague. “What do you mean it’s not Chicxulub proof?”

I think the closest would be "hypervelocity-impact resistant".

Window shields were open

Storm shutters?

But what if it gets too warm?

I know it's not a real question, but it is actually the bigger problem to cool the ISS then to heat it.

Also to distribute it ~evenly around the station.

Wow, it is just so cool we’ve created a little alcove up in space for us fragile humans to live in.

Yes it's impressive how many problems occur in a space-station.

Fun-fact: The training bicycle needs to be suspended otherwise the whole station would start to wiggle/vibrate which can damage the solar-panels...because of one little human on a bike ;)

Little humans in good shape can sustain for several seconds bursts of 1000W+ on a bike. Not so little after all.

Little Ant's and Bee's are even more impressive...well not on a bike but otherwise.

The cost-optimized mundane everyday machines that we expect to move are endowed with 150x that energy output -- and with the ability to sustain it rather than burst it. 1kW is large for a human but small for moving a big chunk of metal. Since the sort of resonant motion would be thoroughly damped if, say, you built a full scale ISS in your backyard, I tend to agree with them that it's notable.

A perfect example is a large water pump, a 250hp electric pump draws approximately 150kW (480v 3ph, around 300-310 amps).

I make Sustainable Sound (1),a bicycle powered sound+light+robot interactive experience… can confirm the impressive power a human can create.

Not just that, but the mere fan vibration is enough to make ISS unsuitable for some particularily sensitive 0g experiments. There was an entire co-orbital module for ISS in the plans (that never came to fruition, sadly) to provide the station with a separate volume with high-quality microgravity, that would be in the same orbit, docking with the station from time to time.
