[X] Plan: We'll Always Have Oak Ridge
The importance of animal testing after we're confident in our spacecraft is in making sure that complex life with human-ish physiology can handle sustained periods of zero-G. For all we know at this point, after a few minutes of zero-G, the heart stops working or something, and it's better if we find that out by a dog dying than a human. Insects or plants don't help with that. That said, we should only launch animals once we are reasonably confident in it; we shouldn't pull a Laika.[X] Plan Punch The Moon
Imo, irl the failures, and perhaps the very attempts at sending animals in space themselves, cemented space exploration as a sacrificial science, where loses are expected and embraced.
If we really want to test that, why not send some insects? Or hell, plants. Those are living organisms that we could learn lots from if they die, and even if they live.
A spider or tomato plant dying is much less important to the public than a pet or Caesar.
You really should read the thread, but I'll bite: It's not a solar sail. It's a solar thermal, like using a magnifying glass to burn paper except instead of paper it powers a rocket. It's a poor man's ion engine, and the peeps here think actual practical ion engines are far enough away for it to be a worthwhile stopgap.so got too ask. is there a reason we are putting a focus on the solar sail thing??
A plant would be no use to use, totally different respiration mechanism. But the spider? That'll work for life support testing if we can't monitor gas concentrations remotely (but if not that is VERY DAMN IMPORTANT to become capable of doing!). Maybe frogs, if we really need something large enough to disect.[X] Plan Punch The Moon

But by metaknowledge we do know what zero-G does to people, and it's not directly lethal. We aren't at risk of political capital loss for not investigating.The importance of animal testing after we're confident in our spacecraft is in making sure that complex life with human-ish physiology can handle sustained periods of zero-G.

That's the problem with liquids, due to the surface tension. This, and 0 gravity, means that if you were to put air inside a water bubble it would stay there, and that would lead to no gas circulation.OK there's one possible issue. I recall an excerpt from ProjectRho of a sci-fi story where the issue was that if you fall asleep motionless in zero g and the air circulation fans stop, the lack of convection means you suffocate in a cloud of your own CO2. Google search results are polluted with some stupid "zero g posture" beds and chairs, so I can't quickly verify. Given how unlikely it is for the capsule's fans specifically to break down just as laika is sleeping though, I am not sure we'd reliably catch that with animal testing.
I object to "poor man's ion engine" when it has orders of magnitude higher thrust and could reasonably keep doing good service with today's technology .You really should read the thread, but I'll bite: It's not a solar sail.

Should we be operating on metaknowledge though?But by metaknowledge we do know what zero-G does to people, and it's not directly lethal. We aren't at risk of political capital loss for not investigating.
