Is it legal to send a satellite into space?
The answer is yes in principle you can. However, The Outer Space Treaty essentially makes each nation responsible for what is launched under their flag, so you would need to find a nation that you could persuade to allow you to launch under their flag.
Has any satellite gone out of the Milky Way?
No, No man-made spacecraft has even left our solar system. The Voyager I probe, launched in 1977 is the craft that has gone the furthest out, but it is still crossing the boundaries of our solar system into interstellar space.
Will Voyager ever leave the Galaxy?
Sometimes, it is written that Voyager and Pioneers 10 and 11 have exited the solar system. Though all of these spacecraft have gone beyond all the planets of the solar system, they have not exited the solar system, based on the scientific definition. To leave the solar system, they need to pass beyond the Oort Cloud.
Have we sent a satellite outside of the Milky Way?
Now, one probe has achieved a milestone in exploration: On December 10, NASA announced that Voyager 2 has entered interstellar space, six years after Voyager 1 first crossed the threshold. The twins are the only two spacecraft ever to venture so far from home.
Is it possible to send satellites to another galaxy?
But that is just the next star, our most immediate neighbor in our own Milky Way galaxy. The next full-size galaxy, Andromeda, is several hundred thousand times farther away. So no, we cannot send satellites to another Galaxy, nor has anyone done so.
Do we send satellites into space to orbit the Earth?
No. NO! We send satellites into orbit around Earth. We send probes to other planets or bodies in our own solar system, some of which become or deploy satellites that orbit those bodies.
Can satellites crash into each other?
Satellites are designed to not crash into each other, which means that it’s very rare that their paths cross, and many of them operate at different altitudes. The ISS orbits at a height of around 250 miles, for example, while other satellites orbit closer to Earth or much further away.
Can a satellite galaxy become part of a bigger Galaxy?
Yes! Scientists have long known that it is possible for satellite galaxies to be disrupted and become part of the bigger galaxy that they orbit. They see it happen in other galaxies all the time, and there is evidence that it has happened here too. One great example is something named the Helmi Stream.
