| Jan 29, 2017 at 15:19 | comment | added | Thorsten S. | Somehow this picture does not seem right. Water in gaseous form is water vapor, not hydrogen and this molecule is heavy enough to be hold down, so why should the loss of hydrogen dry out Earth ?! And no, we not only lose water, we also gain water by the entry of comets. And space being not a perfect vacuum: Show me one apparatus on Earth which is able to produce less than 10 000 times the pressure of interplanetary space. | |

| Jan 28, 2017 at 11:43 | comment | added | Paŭlo Ebermann | Space around earth is a much higher vacuum than in a vacuum cleaner. I guess it qualifies for this word, even if it is not an "absolute vacuum". | |

Updated question in response to a comments given and enhanced explanation with some imagery and a link

| Jan 27, 2017 at 22:20 | comment | added | BLAZE | @Chris Unable to respond as I don't understand the question. What is ISS, negative review? Requesting clarification. Thanks. | |
| Jan 27, 2017 at 19:04 | comment | added | Chris Caviness | So I was using a shop vac to try to clean the solar panels on the ISS and it didn't work. Where do I leave a negative review? | |

| Jan 26, 2017 at 20:40 | comment | added | BLAZE | @Barmar Agreed, but I didn't write the question; so I wouldn't know whether that was what they had in mind. | |
| Jan 26, 2017 at 20:37 | comment | added | Barmar | But for the ones that stick around, the two reasons are the same. | |
| Jan 26, 2017 at 20:34 | comment | added | BLAZE | @Barmar Yes (after looking carefully at it) the statements are almost the same. The reason I said that the "others are wrong" is purely because some of the air molecules do escape. It just seemed to me that those that said "speed of air molecules are not high enough to escape" were thinking that literally none of the molecules had what it takes to escape. This was just my interpretation. Good point though, thanks. | |
| Jan 26, 2017 at 19:05 | comment | added | Barmar | Aren't the two statements effectively the same? "speed are not high enough" just means that the speed is not high enough to counteract gravity. | |

Simply removed the incorrect part
