Space and Red Blood cells. -- Scence daily

I am putting this here as it is to do with blood, so biology seems most appropriate. As I suggested on Mastodon, perhaps we should forget about humans in long term space travel and see if we can develop robots or other similar human like android things to go instead.

This may remove many of the issues involved with long term missions given the distances / dangers involved.

Of course this is not to suggest we should abandon research in to sending people, we may just not be at the right point in technology as yet.
