@MK27:
That's exactly why Sea Launch waited 24 hours before their last launch. It was originally scheduled for Friday, but they were under (roughly), the path of the falling satellite, and couldn't take the risk of any collisions. For political purposes, they don't broadcast why they delayed the launch one day, since they want to maintain good relations with every country.
The private sector space companies are VERY interested in every kind of space exploration. Clearly, very significant finances must be in place for something like a journey to Mars, or the Moon.
NASA has already awarded the contract for the next two rockets they'll need. A slender "toothpick" for low orbit deliveries to the ISS, etc., and a huge rocket for the trip to the Moon, Mars, etc. The big one will use the same solid rocket boosters on it's side, as the shuttle rocket had (no big external tanks, though).
This is a pic of the big STS, (larger and much more powerful than any other rocket, to date):
