Yeah, reporter typing on an iPhone exclusive reportage on how the body adapts in space to weightlessness and if will fat people will ever be able to travel to space.
i've watched so many of these videos that sometimes i forget that there is still gravity for a few seconds and i think i can fly its really weird but its funny
Commander Hadfield, because of your efforts, and your Crew - We are able to grow Together in the Most Important aspect of Life down here on Our Planet Earth and that is Knowledge. Words will never be able to describe the emotion of gratitude nor will History books be able to relay in proper terms, but I just wanted you to know now that you will forever be Our Hero. Love and light. ~tina marie ♥
Thank you for your beautiful pictures, and also your ambition that space travel should become more ordinary. Once that happens, perhaps our leaders might understand how small and fragile our home planet is, and how important it is for us to work together to conserve our lovely home.
Weight is defined as the force of gravity on mass (w = m * g, where w is weight, m is mass, and g is acceleration due to gravity). In space, acceleration due to gravity is essentially 0, so a person's weight would also technically be 0, however in physics they say "unweighable". Mass, on the other hand, always remains constant regardless of gravity because it is a measure of matter. A person who has a mass 150kg on Earth will also have a mass of 150kg on the moon or in space.
Because signal travels longer in that direction. We use satellite dish to communicate the people who are on other side of our planet. It works like we shoot out the signal to the space to satellite and that satellite reflects the signal waves to the receiver and the receiver's response also travels in same way to the sender. So to get the response from the reporter; it's CNN -> Satellite -> Reporter -> Satellite -> CNN station. In this case, it's from station to station direct communication.
Events like this are live..because they can and want to. NASA needs more attention, social media and live 2 way broadcasts like this are one way of doing so. Questions can be pre-selected, demonstrations are prepared. Chris Hadfield tweets from space.
It's not right away, there's about a 6-7 second delay in this video. Also you can't really think that the ISS uses the same technology as a new station, that would be ridiculous.
It wasn't right away it was about a 1 second delay, the reason the reporters can't hear anything for what seems like an eternity is because A: they are using poorer technology and B: the signal first has to travel to a satellite then back down to earth.
Well i cant back it up, but my theory is that the transmissions have less "medium" if you will to pass through. For a transmission to travel on earth, it does sort of a triangle, when it goes to a satellite then to the reporter, whereas when the transmission goes to the station, it only goes "half-way", or a more like a straight line instead of the triangle. Anyway that is my theory, dont know if its true.
Actually ears would probably pop. It's simply pressure differences. In planes cabins are pressurized at a lower (but safe) BAR than at sea level. The same probably holds true for spacecraft, 1 BAR is not needed to live. If air and spacecraft maintained 1 bar of internal pressure stronger material and structure would be needed, adding weight, and light weight properties are crucial in both.
There won't be any ear pain. The ear pain is caused by the air pressure. They're staying in a pressurized room so ear pops won't occur when the get down to Earth
Do you really think this is a live recording? Last time where a question involved eye sight, he was already in the right room with all the equipment required to demonstrate his answer. He is prepared.
Chris Hadfield actually mentioned in another ISS video that their communication was made possible by the same geostationary satellites we use on earth.
The reporter in Yemen may actually be farther away too - the space station is orbiting 400KM over the planet, it may actually be closer to the broadcast station than the guy in Yemen.
Because the tech works like this: Data is sent to a router. Data sent to a tower. Data sent to Satellite. Sent to new tower. Sent to router. However, in space, they ARE the sattelite, so they get the data in half the time.
Weight is an effect of gravity. You are lighter on the moon, heavier on Jupiter. Without an object exerting gravity, you are basically weightless, but not technically weightless. There is always something exerting gravity in space, no matter how small it's effect may be. In space it would make sense to be measured the same way we measure planets, with volume and average density.
Maybe those people were taking notes like the lady that asked the question when she had her computer you could see here arms slightly moving suggesting that she was typing something so maybe they were taking notes or something
Those communications have to be beamed up to a satellite, sometimes hop to another satellite (Maybe even a third) then down to the receiver. However, these communications are going straight from NASA to the ISS. If you followed the data, you would see the Earth-based communications actually have a much larger distance to cover.
If I recall; the ISS is on a 54° inclined orbit. I'm really curious as to why? Is it a safer orbit? Is there solar shielding taking place, or is it just because you can?
Think of it as a bus journey where it takes a trip from the US to Yemen. In order for the information (or the bus if you will) to reach Yemen from the US it has to take two trips. One trip to the satellite, and then another from the satellite to Yemen (and also another two for the info to get back to the US). Whereas for info to reach the satellite the bus only has to reach the halfway point and then turn around again, thus making it much faster. I don't mean to sound condescending at all btw.
But the space station communicates both ways with satellites (duh). It's much more likely that a similar delay existed in this broadcast, however conversation was very static and ordered....The question is asked, everyone laughs, they respond....the delay just isn't obvious. On a news show a two way dynamic conversation is happening the delay is very obvious. This is my theory on the question.
When they communicate with the reporter in Yemen, The signal is sent from earth, bounced off a satellite that is orbiting earth in a geosynchronous orbit (about 35,786 km above the earth) and then back down to Yemen, making the distance 71,572 km. The space station orbits at an average of 370 km above earth. That's an incredibly shorter distance.
So what I'm mostly taking from these things is that unless you go to space for, oh, something like a week at least, it's actually a pretty horrible experience. All bunged up, sick, clumsy and dizzy. Sounds like having the flu. And then of course the awesome starts :D
Well, the distance between the US and Yemen is bigger than the distance between US and the ISS as long as the ISS is currently above the US. And also, the video could be edited so that you don't have to wait for 5 seconds every time ;)
Space station is only 230 miles above the surface of the Earth. This is not an advantage at the speed of light. There is most likely a delay in communication similar to what we see on news stations, it is just not obvious in this broadcast as there are no dynamics in the conversation to make the delay apparent...My hypothesis, but still better than the answers I've been seeing to the question..../facepalm
did nobody else notice the girl with the Doctor Who case on her phone?!? She's there having a chat with real guys in space .... I cant convey how topical that is.
At the very end of the video the guy in the middle starts to float off and is wiggling his feet to try and grab onto something but uses his hand in return.
Either because the ISS is not that far away (about 300-400 kilometers up) compared to Yemen or they just edit out the delays. Not sure which one though.
