The SpaceX Dragon cargo craft is on its way to the space station where it will be captured Saturday at 10 a.m. EDT by astronauts Nick Hague and Christina Koch. The last Dragon to visit the station is pictured here on June 3, 2019, moments before being released from the grips of the Canadarm2 robotic arm. #nasa #spacex #dragon #international #space #station #robotics #earth #astronaut #csa #unitedstates #canada

randalscott42 @yanu.arian I have seen the flat earth so called "evidence" and have found it deeply flawed. An example is trying to apply the Raleigh principle to things going over the horizon that mysteriously only works from the bottom up and not side to side or any other dimension. So called fe "science" is full of extraordinary twists, turns, convolutions and downright misrepresentations (i.e. lying) trying to make visual evidence fit the flat earth where the simplest model that fits ALL the evidence AT THE SAME TIME is that we are living on a 12,742 km sphere that rotates once every 24 hours orbiting the Sun at an average distance of 149.6 million km taking 365.24 days to do so. But none of this will matter to anyone who wants to remain wilfully ignorant.

randalscott42 @yanu.arian I have seen all the so called fe "evidence" none of which works in the real world. Even the Great Charlatan of "fe scientism" Mark Sargent demonstrated the Earth's rotation using a laser compass. Flat earthers on YouTube are all charlatans and fakers making a comfortable living preaching their drivel to the terminally gullible who support them. As I have said I have seen ALL your "fe 101" so called "evidence" and have found it wanting. Open your eyes to the reality! Keep an open mind, but not so open that your brains fall out or let others fill it with foolishness. Please note I have kept this conversation civil. Have a nice day.

aeeluo @lamata70 so. Thanks to some researches (which I doubt you did) and the sources if you wanna search by yourself : https://space.stackexchange.com/questions/9087/how-often-does-iss-require-re-boosting-to-higher-orbit and https://en.m.wikipedia.org/wiki/ISS_Propulsion_Module. So, yes. The ISS has a propulsion module which is used to reboost the ISS. HOWEVER, the supply ships which dock to the ISS are also used to do small reboost. So, I bet you haven't search to know if these ships have still fuel or not. But yes they have fuel. So, I bet you haven't done any researches...

wce279 @doctorblizzard Im sure they could make the vessels multi purpose. I remember back when they started building the iss they thought of maybe using the main rocket booster from shuttle launches as parts for the space stations main structure but being able to transform that would've been very difficult but these are smaller and i believe already air tight so should be able to be used. As for the size and drag issues i don't think that comes into play as it is continually being expanded and improved.

doctorblizzard @wce279 I mean it absolutely comes into it. Yes it expands sometimes but not by much. The amount of waste they would have built up at this stage would be huge, the ISS has been up there for what 19 years? By this point waste modules would have probably made it maybe 10 times it's size? Not accurate but you get the point. Plus you have to take into account the additional weight all that rubbish would add. Plus the emotional stress being surrounded by rubbish would add

doctorblizzard @wce279 I'm not actually angry in the slightest lol. And yes I do but you do realise there are velocities and angles where things bounce off the atmosphere instead of just hurtling through it? Gravity isn't the only force in play. Basically as I've said, it would be impractical and, tbh, probably not very cost efficient to rework a garbage ship. Nice idea though
