Why does NASA not launch rockets from weather balloon tethered platforms?

wait... they don't use rocket assisted (for show ,everyone likes fireworks)hydrogen "balloons" already?!

Hydrogen is what? 14 times less heavy then helium or something. any one know off hand what the lifting power of 700000kg of Hydrogen would give compared to a helium balloon or a hot air one/weather balloon? the atmosphere goes up to what 1000km? is anything really actually in space when it is in orbit? like I'll agree it's close but it's not "in space" it was My understanding orbital velocity was just falling faster then gravity was pulling it back down.. *grabs tin foil hat* so are those rockets or balloons is what we should be asking that are going upthere now.. Hydrogen blimps seem to have a pretty easy time staying afloat.... that roll over the shuttle did with the tank on top the rest of the way up is pretty blimp like looking...and how balloons lift stuff. and nasa would be laughing all the way to the bank all along.

Combusting hydrogen (hydrogen and oxygen mixing together with a spark added) is far far far more energetic than the lift provided by lighter-than-air helium rising through the air.

Maybe, but that depends on what you mean exactly.

An orbit around Earth can be defined as falling back to Earth due to gravity AND moving sideways (parallel to the ground) with enough velocity that you actually "miss" the ground as the Earth's surface curves out from under you.

To illustrate this, let's go back to the "Newton's Cannon" graphic I posted earlier:



If you are moving too slowly in a "sideways" path that is parallel to the Earth's surface (path A), then gravity pulls you back to that surface. Move a little faster sideways (path B) and as gravity pulls you down to the surface, the surface itself curves under you a little. However, you still would be moving too slowly, and you end up hitting the surface again. If you go just the right velocity parallel to the ground (path C), you can fall back to Earth AND move "sideways" fast enough that as gravity pulls you down to the surface, the surface curves away from under you enough that it curves away from you before you get a chance to hit that surface.

And THAT'S an orbit.

Well they do. All the so-called "UFO" sightings are government weather balloon platforms used for launching rockets. This is why every time someone reports a UFO, the government tells them it's a weather balloon. They've been telling us the truth all along but no one listens.
