And of course, they can't turn it off after they've touched down because they will likely no longer have a comm link!

- LeifCarrotson 10y agoSure they can. It has a computer. Tell it "power down in 1 hour if you don't have a com link".
- 3chelon 10y agoYes, but there's a fairly high risk the computer or its power supply will malfunction on impact.
- Tuna-Fish 10y agoThere is no need for that if statement. Rosetta's antenna needs to be very precisely oriented to maintain connection, and it is attached directly to the side of the spacecraft (as in, it cannot be aimed without moving the entire spacecraft). The moment Rosetta hits anything, the antenna will be knocked out of alignment, and if a corner of it is resting on the comet, it cannot orient itself properly to establish a link.
