Yesterday we learned about all the different layers of earth's atmosphere. The I.S.S. is in the THERMOSPHERE, about 440 km away from us. Here is some of our maths about that - the 4 tamariki are standing on the edge of the EXOSPHERE, which is much thicker than all the other layers of our atmosphere.
Today we had a quick look at how far it is from Earth to the moon and Mars. They are MUCH further away than the ISS. The moon is over 400,000 km away from us, and Mars is 67 MILLION km away!
This means that, travelling by rocket, it takes about 2 days to get from Earth to the ISS, about 3 days to reach the moon - and 6 - 7 months to reach Mars! There is SO much exciting learning to be done about Mars... but we are going to stick with our ISS learning. If you want to learn more about Mars with your tamariki, this is a great place to start: NASA Mars for Kids
Finally, we bamboozled ourselves by starting to learn about microgravity. Watch this video and see how much information you can 'catch' - it sure is a curious concept!
