Has anyone else noticed that in the aritcle they mention "The ballute is jettisoned from the spacecraft once the desired capture orbit is achieved, the company said."
Do we need any more litter in space - especially earth orbit?
We all think of balloons being filled with light than air gasses, but in this case they will want both low compressed volume and low weight for takeoff. So it may well be that they use liquid Helium - in which case would they hang around in orbit - once the drag of the ship is gone might they bounce off the atmosphere as they are still moving at orbital velocity.
Even if they go sub orbital velocity they are still intact balloons at the edge of space and they are not going to sink down the planet easily(presumably they will be quite strong).
I am sure they will think of it - but it would just be nice to see them mention retrieval/disposal with the increasing amount of junk in space these days...
