The moon landing and another big space anniversary
It\u2019s 50 years since the moon landing and 25 years since Shoemaker - Levy 9 crashed into Jupiter. The Apollo missions returned to earth with cargos of moon rocks and the comet crash showed us what happens when celestial bodies collide.
We look at the significance of both this week, and also contemplate a return to the moon. What will the next generation of moonwalking astronauts do there?
One thing\u2019s for sure, they\u2019ll be examining moon rocks once more \u2013 though this time with a range of scientific tools which hadn\u2019t been invented when the Apollo missions ceased.
