This just out. Not earth-shattering, but colorful - maybe handy as an up-to-date

Or could we suggest elements of the Vega Venus missions that included a balloon?

Or could we suggest elements of the Vega Venus missions that included a balloon? My understanding is that the challenge at Titan is communications. If you build a single large balloon or lander, you can put the antenna, transmitter, and power system to communicate directly with Earth. If you do lots of landers, balloons, or combinations, then you need a relay orbiter. The second craft by itself appears, from my readings of the cost estimates, to cost ~$2B, probably less if you strip all the instruments off. I could envision a mission that had several landers and the flyby carrier could act as the relay. Such missions have been proposed for Venus where the lander life is short. I don't know if such a mission would be considered worth while by the scientific community at Titan. Having seen how much more is learned from a lander when scientists have time to plan samples, etc, they may feel that a single longer lived lander would contribute more than a number of short lived landers. I like your list of proposed landing sites. -------------------- |
