The Cosmos 1 Update The Planetary Society

The spacecraft for the suborbital test flight of our Cosmos 1 solar sail is now repaired and ready for launch. We’re on track for the orbital test flight late this year, but we will of course re-evaluate the schedule when we have the results of the suborbital test. The spacecraft is now ready to go, but we still have to wait for the Russian navy to assign a time slot for the submarine launch. We had been hoping for a June slot, but it looks as though the soonest the navy will be ready for us is mid-July. We hope to be able to announce a firm launch date by the end of this month.
