So next time we launch a bigger rocket we know what changes need to be made beforehand. They also are looking to add personnel, including a vice president for business development and vice president of engineering. They are looking for people experienced in the aerospace industry who can bring valuable aerospace know-how. The team spent two months in Australia last summer taking part in the Startmate and Moonshot accelerator programs and plans to conduct at least some of its launches Down Under.
Leo Aerospace got its start at Purdue and received guidance from the Purdue Foundry , an entrepreneurship and commercialization accelerator in Discovery Park's Burton D. Morgan Center for Entrepreneurship. The rocket scientists developed their business plan and learned what they needed to do to move forward. Trouble with this page? Does this seem correct?

E-mail the story Successful launch of rocket from high-altitude balloon makes space more accessible to microsatellites. I also assume a balloon would be needed because a rocket would be moving to fast to work on capturing the descending tether and you would need a relatively stable platform for the crew to work on knitting the final pieces together in a similar way to the joining of the intercontinental railroad in Utah.
It may be possible, but won't help much if you want to reach an orbit. This is easily seen considering the energy budget. Sign up to join this community.

Could it be possible to launch a rocket from a balloon? Ask Question. Asked 8 years, 2 months ago. Active 4 years, 9 months ago. Viewed 39k times. Improve this question. Nallath Nallath 1 1 gold badge 4 4 silver badges 9 9 bronze badges.
My first thought is; while it might be possible; overcoming the logistical issues would cancel any benefits. Obviously you can not launch from the top of a balloon, and from that issue the logistical issues flow. The platform could be below the baloon and the rocket could be launched from a tube that passes through the baloon a bit like a rocket launcher or torpedo tube. More of a problem is the sheer economy of scale.
You'd need enormous balloon to lift any considerable payload with sufficient amount of fuel to place it in the orbit. Air pressure hydrogen is a very low energy density fuel.
There's probably more energy involved in compressing it than could be recovered by burning it. Show 6 more comments. Active Oldest Votes. Description High altitude balloons would suspend large pulleys that are basically pulled by trains. Feasibility Clearly you can launch something to orbit from balloons, but if there's no economic case for doing it, it won't ever happen. Improve this answer. Andrew 2 2 bronze badges.
I don't know if it ever actually gave an upward speed of the mini-rocket at the point of detachment, so it would be premature to assume it's over Mach 1, or that such speeds would be practical. One thing I previously seemed to miss is that the rail tracks aren't actually to exert force, but only to adjust for slack in the tether, like that spring thing on the back of bicycle wheels that allow you to shift to different sized gears.

So your dollar figure is high by about two orders of magnitude. Though only if the ballon structure scales linearly, which it doesn't.
Also I think your He cost per unit volume is about a factor of two low. The reason it's hard to get to orbit isn't that space is high up. It's hard to get to orbit because you have to go so fast.

The space shuttle stack, for instance, burned through nearly half its mass in the first 90 seconds after launch, at which point it's still going quite slow compared to its eventual orbital velocity and it's not even , ft up yet, IIRC.
The enthusiasts at JPaerospace intend to have their airship accelerate by an ion engine during many hours or days in the thin air at high altitude. Until it reaches orbital speed. And they do more than photoshopping, they actually build stuff which are full of hot air :- jpaerospace.
When it's high enough, the upper stage will do the major burn to achieve orbital velocity. The technology will transport unmanned rockets to high altitudes. Nasa space laser tracks water depths from orbit Space laser makes height maps of Earth Funding given to Snowdonia rocket launch centre.
