Amazing piece of engineering. Far exceeded expectations. I know the team must be proud but sad.Mars helicopter is down. Permanently.
NASA's historic Mars helicopter Ingenuity grounded for good after 72 flights
Part of one of the rotors broke off. It has a good run. Now it is going to be a museum piece one day.
38 years agio today. RIP37 years ago today we lost Challenger and the seven brave astronauts aboard.
The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God."
