Google co-founder Sergey Brin said he was amazed that so many competitors had signed up so soon after the prize's announcement."I was floored," Brin told the team members and reporters who attended the press conference. "We had no such expectation."
iamlucky13 - 25/2/2008 3:54 PMRussian Dnepr might be a good candidate. Decent payload and price, and it exists today.
Even if a Falcon 9 or Taurus II is successfully operating by then, that's no guarantee a launcher will be available between COTS and other customers.
Piggybacking on something larger could potentially be an option, but if you're a commercial satellite operator putting a $100 million plus payload into orbit, would you want an experimental lander sharing a rocket with you?

Personally, I've had strong doubts from the beginning anyone can raise the capital to do it.

It did did not do its job completely though ..
hop - 25/2/2008 5:58 PMThey are likely to cost significantly more than the first place prize for launch alone. You might get a deal on a development flight, if no big customers are willing to take the risk. Angara might also end up in this category if it actually comes online in the next few years.QuoteI think even a Dnepr, which I would suspect to be the best option, costs somewhere around $20 million to launch. I'm sure no one is going to make a profit off of this unless they either figure out either a marketable technology or piggyback.QuoteExperimental (including student built, HAMSAT etc) secondary payloads do fly, but are relatively rare on GEOCOM flights. AFAIK this has more to do with the fact that they try very hard to use the full capacity of the LV, since station keeping fuel is one of their major lifespan limits.Good point about the fuel mass.I know a lot student satellites etc. fly as secondary payloads, but from what I've seen, these mostly use either off-the-shelf hypergolic or cold gas thrusters...if any at all. As a lunar lander would need relatively large and complicated set of thrusters, I think there's an additional risk there for anyone sharing with them. Even something really simple, like a fitting with a rubber seal that the x-prize team didn't realize gets brittle and cracks at low temps causing a hydrazine leak could make a mess of stuff, I should think.
