7.5? Wut? Well today I will just continue with the Jason-3 satellite which was launched yesterday.
So yesterday in the evening Falcon 9, the launch vehicle of SpaceX carried Jason-3 to low earth orbit. This is somewhere between 160 and 2,000 kilometers, yes there is such a big difference.
For Jason-3 it is 1,336 km above Earth’s ocean and before it rotates once around Earth it takes him about 2 hours.
I was watching the launch on NASA TV at the time of the launching. While there was lot of fog so I could see only the top of Falcon 9, still when the flames started to burst everything went kind of red and white.
Falcon was able to fly faster than 2,000 km/h if I remember correctly. Jason-3 was successfully deployed and now it will take 6 months before it will be fully operable because all the instruments must be calibrated and then it will work with Jason-2 which orbits several kilometers above.
As I mentioned in the last post, it is going to measure the height of oceans. Jason will be able to cover 95% of Earth’s oceans in 10 days, amazing.
After the deployment, SpaceX tried to land Falcon on ship named: Just Read The Instructions. Sadly they were not able to make it, everything was going well but then the collet was not working properly and Falcon fell on one side instantly exploding. What is important is that they can learn from mistakes, and that is really important.
