I hope it can be sent somewhere neat once they are done testing. But I assume it’s not configured for long range communication.
It would be cool if it could be sent, slowly, to a “nearby” body.
Iirc, solar sail designs like this can actually go stupid fast when properly propelled by something like a laser array.
What's fun about these is that the mass of the actual vehicle can be much smaller if it doesn't need to carry rocketry and fuel on board. So even though they'll never compete with rockets for power (energy used over a specific length of time), starting at a lighter weight and never running out of fuel means that these systems could theoretically exceed the top speeds (relative to the earth) of our fastest rockets, given enough time.
How do they slow down or stop; is it by reversing the sail?
