On July 21(Australia) 1969 as a 7 year old I watched Neil Armstrong step onto the moon.
The first human to achieve this feat.
On September 27 (Australia) 2022 at 7.24am I watched the DART Spacecraft slam into the Asteroid Dimorphos at 14,000 mph.
The mission is to see if the impact has any effect on the trajectory of the asteroid - change it’s course.
A momentous achievement, sending a small spacecraft to rendezvous with an asteroid 6,800,000 miles from Earth.
With live feed so all on Earth could watch it.
Bam! NASA’s DART spacecraft slams into ‘moonlet’ in asteroid system
DART hits asteroid Dimorphos!
NASA’s DART mission hammered its target asteroid into a new shape.

Yes, and Hubble was a big thing for me too.
The reason for me going into my first Internet Cafe was to look at the Solar System pictures it gave us.

Those first pictures were flawed.
Did you see the corrected ones?

I wonder when the next asteroid is due to whizz by … or more mundane … any large chunks of space junk.
Makes you wonder how much rubbish is floating around in orbit out there.

You’d kinda hope that eventually it’d either fall to earth (or burn up along the way) or leave orbit. I wonder is anyone’s estimated how long it’d be for man made debris to clear itself if we stopped firing more stuff up there.

And almost as dangerous … is blue ice from commerical aircraft.

Surely that turns back to liquid soon enough? Or am I getting confused with something else.
