Yes, it is the folly of man, or rather Elon Musk, and can be seen as a hubris filled PR stunt: launching a Tesla Roadster into space just because. But is a good upgrade from the wheel of cheese he launched in 2010, and it sure beats lumping blocks of concrete into orbit to see if a rocket works as planned. Landing 2 boosters to be re-used is no mean feat either even if the core engine missed its landing site and crashed, nor is reducing the cost of a launch 10-fold. The successful test launch of this Falcon Heavy shows Space X is more than serious about pushing development forward. Having fun by hurling a car into space is just the cherry, not the cake.
The resulting live video footage of the empty space suit behind the wheel with our blue ball circling in the background is pure fun. Topped off by a Don’t Panic message on the dashboard. I only hope Star Man that as rumour has it indeed brought a towel for the next leg of the trip in the general direction of Mars and then ever onwards.
