from the JPL database wrote:Tesla Roadster (AKA: Starman, 2018-017A)
NOTE:
The trajectory estimate will be updated here in the days ahead if more
measurement data is reported.
LAUNCHED:
2018-Feb-06 20:45 UTC by Falcon Heavy (FH-1) from Kennedy Space Center, USA
(launchpad 39A)
BACKGROUND:
Dummy payload from the first launch of SpaceX Falcon Heavy launch vehicle.
Consists of a standard Tesla Roadster automobile and a spacesuit-wearing
mannequin nicknamed "Starman".
Also includes a Hot Wheels toy model Roadster on the car's dash with a
mini-Starman inside. A data storage device placed inside the car contains
a copy of Isaac Asimov's "Foundation" novels. A plaque on the attachment
fitting between the Falcon Heavy upper stage and the Tesla is etched with
the names of more than 6,000 SpaceX employees.
After orbiting the Earth for 5 hours, a third burn by the second stage was
completed at approximately 02:30 UTC Feb 7, placing the dummy payload in a
heliocentric orbit having a perihelion of 0.99 au and aphelion ~1.67 au.
PAYLOAD MASS:
~1250 Kg
Mars is about 1.5au and the Asteroids are 2.2-3.2 au so I think the BBC have understated the situation a bit

I would myself have written beyond.
Whatever way you look at this it was really impressive. There are a number of good videos of the side boosters landing which include the sonic booms

Amazing to think that the average car in space is better than the average car on Earth right now...

Not much use when there are infinitely fewer charging points though.
Scott.

But there isn't much wind resistance or road friction out there either...
Sounds like a reincarnation of the old Mobil Economy Run: when it trundles past Mars, Musk can advertise that his car did 34 million miles (0.36 au for petrol heads) on one charge. The
Tesla Mars sounds like a good brand name, if a bit too martial and Top Gearish.

Well as it was the 4th electric car to be launched into space, the other 3 being parked on the Moon, I'd say that the average for cars in space is much lower than you'd think.

Aren't the ones on the moon, erm,
on the moon?
If we agree that the ones on Earth arent '
in space', then I'd class the moon-held ones in a similar position, so as far as I know there's only
one '
car in space' at the current time....

And the Moon isn't in space?
You know, where you need a space suit to survive.

It is, yes.
But so is the Earth, so when we're comparing something being
Earth-bound with something that's 'in space', I think it's fair to think of something that's
Moon-bound as also not being in space.....
