The line following the title of BBC's Elon Musk SpaceX rocket on collision course with moon reads:
A rocket launched by Elon Musk's space exploration company is on course to crash into the Moon and explode.
The collision is due to happen on 4 March when the rocket will explode as it makes contact.
"It's basically a four-tonne empty metal tank, with a rocket engine on the back. And so if you imagine throwing that at a rock at 5,000 miles an hour, it's not going to be happy," Prof McDowell says.
It will leave a small artificial crater on the Moon's surface.
Bill Gray, who uses software to track near-Earth space objects, projects that it made a close fly-by on 5 January. On 4 March it's likely to hit the Moon's far side, he says.
In 2009 Prof McDowell and other astronomers performed an experiment in which a similar-sized rocket was crashed into the Moon. Sensors gathered evidence of the collision so they could study the crater.
That means scientists are unlikely to learn anything new from this crash, Prof McDowell explains.
Question: Will the seven year old spent upper stage rocket body really explode upon impact? Was it not passivated for some reason?
