I’d read about SpaceX but hadn’t paid a lot of attention to what is happening, so I was pretty excited to read that they just lauched their latest rocket, Falcon Heavy. The rocket launched from Cape Canaveral and is hugely significant: the rocket is intended to be reusable and it’s the heaviest rocket ever launched. The two outer boosters landed safely back on earth but the centre core didn’t land safely althought it was supposed to. The 27 engines produced 5 million pounds of thrust at liftoff, meaning it’s able to take a payload of 140,000 pounds and put it into the earth’s lower orbit. The launch video is 35mins, but all of it worthwhile viewing.
To test the rocket’s capacity meant trying to put a heavy object into orbit. While SpaceX could have just put a pile of scrap metal, a useless satellite, or something unimaginative, they put the silliest thing Elon Musk could imagine: his red Tesla Roadster. Definitely a great sense of humour, in the passenger seat is a spacesuit wearing a seatbelt just like it’s driving the car that is called Starman.

Other cool trivia associated with this launch, aside from the obvious supercool thing that THERE’S A CAR IN ORBIT AROUND EARTH:
- the launchpad was the same one used for Apollo 11
- the rocket launched to David Bowie’s Life on Mars
- there’s a sign that says ‘Don’t Panic’ on the dashboard of the Tesla
- apparently inside the glovebox: Asimov’s Foundation series, a copy of The Hitchhiker’s Guide to the Galaxy, and a a towel
Originally the Tesla was headed to Mars, but then it overshot and they said it would go into the asteroid belt. NASA calculated the Tesla’s orbital trajectory and they predict that it will stay closer to the sun and end up in an orbit somewhere between earth’s and mars’. It’s still visible from telescopes but will soon travel too far away. Astronomers say it won’t be visible again until late 21st century. TIL NASA has a articifial object database of things in space.
Trivla and coolness aside, the reusability and power of the rockets have the most value. They are still testing, but already on the schedule is a communications satellite from Saudi Arabia and a test payload for the US military.
