New Buoyant Spacecraft Concept

For the purposes of analyzing the characteristics of buoyant spacecraft, we will develop a conceptual mission profile for a lighter-than-air vehicle designed to launch 10,000 kg of payload to low Earth orbit.  It will dock with a space station or release satellites and then return to Earth. This payload mass was chosen as a representative [...]

Rocket Innovations: Buoyant Spacecraft

By |2020-03-21T17:42:57-05:00September 8th, 2014|

The fundamental kinematic characteristic of orbiting spacecraft is high-velocity ballistic trajectory, which can only be achieved at very high altitude where drag forces drop to near zero. Thus, the problem of launch to orbit can be decomposed into two separate issues: altitude and velocity. Rockets solve this problem all at once, using reaction force to [...]
