Hi

I am just a simple engineer.
Can you tell me about the Pegasus launch, please

Is it a launch in to orbit, or a launch and transit to Moon ?
Even if it's to lunar orbit, how would you land them ?
I guess there is a bit of difference.

Michael
Pegasus is interesting for its low cost but also because it don't need a launch pad

it's lauched at around 40,000 feet with a modified jet and is able to put a 1000 lbs. payload in low earth orbit

half of this weight must be used for the trans lunar injection booster, the remain weight will be used for the little (200 lbs. max) moonrover and its lunar braking engine and airbags landing system

a direct earth to moon launch, with LEM-style landing, is more efficient but too complex for first launches
