My goal to learn more about rosetta that when to comet and other thing that I want to learn about I will share with other people that they want to know more. My another goal to make a comet from 3d printer
It moves at a speed as great as 135,000 kilometers per hour. comet
They land on comet 12 November 2014, 17:32 UTC (UTC stand for Universal Time Coordinated)
It side is 4 kilometers across
The Phillae is 100kg
The total mission cost of Rosetta close to 1.4billion Euros of which the total Philae costs are 220 Million Euros
Rosetta was launched on 2 March 2004, 07:17 UTC (UTC stand for Universal Time Coordinated)
Philae hibernation on 15 November 2014, waking up 13 June 2015 18:18 GMT (Greenwich Mean Time)
They released at a height of about 22.5 kilometres from the centre of the comet and will touch down on the comet at walking speed, minimizing the risk of an incident
It 186 million kilometers from the Sun
Earth that is between about 800 million
This work is on Week 2
The Rosetta short the information back to earth takes 28.30 min in the speed of light.
It weight 3 billion tons
North pole is in the middle
the comet they think to comet join together and they got different material that why in the middle the evaporate more
The comet rotated once in 12 hours
That comet is floats in water went we put in water 90% in water and 10% on top of the water.
Time to fall 1 meter=120s=2 minutes their no air resistance
On their it a thousandths less than a g. Example: if you wave 200Ibs on their it will wave 2000Ibs
Escape Velocity on 67p is v=0.5m/s or 1 mph.
If you jump on earth just 0.5in it ok but in 67p it will that you away from the 67p and never see you again.
What the Rosetta drop the Philae to the surface of 67p it take 7 hour
The camera have every side on the Phillae
They use an x-ray the comet by using a ratio signal to the other side where the orbit spacecraft is we want to see what is inside the comet The Phillae have the battery
When they go at the first time they reduce 1 cup/s but went it near the sun in will reduce Galan /s
Solar powered 100 ft solar panel span 850watts
