Cubesat Launch Ends in Failure

Change writes "The CalPoly Cubesat group's launch yesterday has been a failure. It seems the first stage did not separate from the Dnepr rocket properly, and the vehicle crashed about 25km south of the launch site. More will be known when the debris is recovered and analyzed. A second launch is still in the works, but the loss of the 14 satellites from this launch is an unfortunate end to quite a lot of hard work of many engineering students."

This has been looked at a few times...but the only launchers that currently have payload recovery capability are manned ones (for obvious reasons).

In general, while losing a payload sucks, it doesn't justify the weight and monetary cost of a payload recovery system and the infrastructure required to go get said payload wherever it lands. The satellite itself would end up needing to be a much more robust design to survive the dynamic environment of an ascent abort.

It's all a numbers game - with the worldwide launch success rate around 97%-98%, it's simpler/cheaper simply to buy the insurance or eat the loss.

Many of these less proven launch systems (such as Dnepr, Falcon) have given very inexpensive rides to orbit to help establish a track record while they work out development issues. The track record is important, because an established launch record helps lower the insurance premium, which is a very large fraction of launch costs to commercial customers. That's why you see a lot of student projects (which are done on the cheap, and usually are uninsured) blowing up.
