CNN: mission to mars
 

that's pretty impressive shit.

Most amazing thing is: how is a device able to communicate
with earth over such a distance.

Must be fake.

yeah.. just like the moon landing...

also.. didn't we already do this a couple years ago?

The Pathfinder fiasco i believe.

All Fake. Space Race Bullshit :321GFY

Ya and movie directors are commenting that the production is quit poor and low budget like!

Radio

been around for at least a couple of weeks now.

some dude named Marconi is to blame.

freekin Guido's !

lol

tranmitting a uhf signal from a small device over 300 million+ miles
in a few minutes is pretty amazing.

yes you are right but it can be done.

as a kid I was into Ham Radio and the ham op's did have a satellite.

took some doinf but I diid get into it and heard myself get into it.
for real.

radio sigs travel at 360,000 miles per second or something like that.

yeah I know hard to believe.


how about your internet connection? how fast is that?

exactly but the idea of "a radio signal at 360.000 miles per second" is difficult to imagine.

Unlike a signal tranmitted by wire a radio signal is very abstract
and although humans (like you) understand how things work
i think its impossible for the human brain to really grasp the process behind it.

Puzzles me.. but then again: i have trouble hitting the 'post reply' button

:winkwink:

Cool :thumbsup

very interesting

Space is a vacuum so there is zero friction. The electrons of the transmitters can flow perfectly.

To be precise electromagnetic signals in space travel at 299,791 Kilometers per second.

The distance between Earth and Mars on landing day was about 170 million kilometers. Takes about 9 minutes 46 seconds for the radio and video signals to travel that distance each way.

i find that kind of stuff amazinly interestinf

Yea man, that kind of stuff is great. :winkwink:

no sign of marvin yet :(

I love how the thread is called 'Cnn Mission to Mars' .. hehe, shouldn't it be the Nasa Mission to Mars?

check it out here..

this is pretty bloody amazing, so far this has been an absolutely amazing month for NASA, and we are only a few days into it..

Elvis is not dead
I'm sure about this !

A friend of mine who talked to another friend saw him.

:helpme

Of course it's possible.

It's amazing that people making cash over the internet don't beleive this or don't understand this (radio waves).

Amazing................

It's frightening when people dont know that the speed of light in a vacuum is only 186,000 miles per second, so if you got your radio signals transmitted at 360,000 miles per second, I think the government, NASA, telecommunications firms, and just about a ton of other people would be interested in your research. :Graucho

No it's not frightening. sumphatpimp said "360,000 miles per second or something like that"

Go ask 100 people right now and how many would know the speed of light? Probably 5. They would be those who actually took and remember their high school physics, Science proffessionals and Space nerds.

Well done NASA. More pics :)

Now lets find some aliens :Graucho

Doesn't it take like 30mins for data sent from Mars to reach Earth?

they did it

great thread..

I was wondering about the signal transmission

but was too lazy to look.. :)

In Kilometers per second its 299,791

9 Minutes 46 seconds to be precise (each way of travel time).

Amazing.. you don't happen to know the error rate that occurs when sending transmissions from Mars? I'd imagine it would be pretty damn high!
