The obvious things like the effect weightlessness has on your skeleton and muscles, but more surprising is that it damages your eyes as they have a very specific pressure in them that is effected. I guess we’ll have to wait until we reach the science fiction ability if anti gravity devices. a few years ago i was at a conference and the topic was what would the ionising radiation dose to an individual who went to mars. the conclusion was a person would recieve around 4.5 sieverts. note the LD50/30 which is the a dose if recieved 50 % of people would die within 30 days is estimated at around 5 sieverts. this suggests that after this around 50% of people would probably be dead within 30 days and one other conclusion is others would have a much higher probablility of suffering from radiation induced illnesses (cancer etc) Quote

John Findlay Posted August 2, 2020 Posted August 2, 2020 When you witnessed Apollo 11 aged 6. It's difficult to get excited at what has followed. Quote
Cade Posted August 2, 2020 Posted August 2, 2020 There's tons of exciting space stuff going on all the time. Never gets reported in mainstream media. NASA just sent another rover to Mars, and this one has a drone on the back for aerial pictures and scouting. This rover will be collecting rock samples and leaving them in sealed tubes, with a future mission aiming to collect them up and blast off from Mars back to Earth. That would be a huge milestone. SpaceX's Starship is continuing to be in development, paving the way for cheap, reusable rockets able to land then get back into orbit and back to Earth without needing to dock with a command module. This could allow longer human missions to the Moon or even Mars. China is hoping to collect and return moon dust samples to Earth with a new rover. A Japanese craft has already landed a cluster of probes onto an asteroid, collected samples and is on it's way back to Earth with them. There's dozens of others on the go, too may to list. Quote
JFK-1 Posted August 2, 2020 Posted August 2, 2020 Perfect splashdown. Sometimes it rolls upside down in the water but they're upright and stable. Apparently the water is like glass. Quote
Cade Posted August 2, 2020 Posted August 2, 2020 Half a dozen feckin imbeciles in private boats hanging around the splashdown area Quote
Cade Posted August 2, 2020 Posted August 2, 2020 Scott Manley's next video should be a good one. Quote
Cade Posted August 2, 2020 Posted August 2, 2020 Bit of bother with some toxic fumes coming off fuel residue but nothing more than a delay to clean it out. Quote
