No one could have dreamed we were being scrutinized, as someone with a microscope
studies creatures that swarm and multiply in a drop of water. Few men even considered
the possibility of life on other planets and yet, across the gulf of space, minds
immeasurably superior to ours regarded this Earth with envious eyes, and slowly and
surely, they drew their plans against us.
If the engines stop and you have to deploy a parachute,isnt it going to ba a rather hard landing with all that kit attached to your back, as I thought in a normal (without a jet pack attached) landing you took some of the speed out by collaping to the floor as you touched earth, surely you wont be able to do this .. or am I completely wrong ?
Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed.
Transient Crater Diameter: 9.78 km ( = 6.07 miles )
Transient Crater Depth: 3.46 km ( = 2.15 miles )
Final Crater Diameter: 13.2 km ( = 8.22 miles )
Final Crater Depth: 644 meters ( = 2110 feet )
The crater formed is a complex crater.
The volume of the target melted or vaporized is 1.81 km3 = 0.435 miles3
Roughly half the melt remains in the crater, where its average thickness is 24.1 meters ( = 79.2 feet ).
A few random figures later:-
our Inputs:
Distance from Impact: 10.00 km ( = 6.21 miles )
Projectile diameter: 500.00 meters ( = 1640.00 feet )
Projectile Density: 8000 kg/m3
Impact Velocity: 72.00 km per second ( = 44.70 miles per second ) (Your chosen velocity is higher than the maximum for an object orbiting the sun)
Impact Angle: 10 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock
Energy:
Energy before atmospheric entry: 1.36 x 1021 Joules = 3.24 x 105 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 1.9 x 106years
Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree).
The impact does not shift the Earth's orbit noticeably.
So this = BIG HOLE....
Yes I had a dodgy Beeb, It used to lock up all the time when it got hot, and I had to spray the ALU chip with some freeze stuff to unlock it. Mine was second hand but had a Econet connector so its past was probably a bit dubious,and I had aMusic 500 flashed to make it a 5000 and a Music keyboard built from a kit from Watford Electronics. Also had the sidways ram module in it and something called Replay that you could input cheat codes etc that were printed in magazines etc.
Still got a BeebEm emulator and a load of disk images,fire it up occasionaly to drive down memory lane...
