I might as well post about todays stuff in class today , due to phil's lack of constant posts.
Hmm.... Im already starting to forget what we did.
We got some sheets about launching the spacecraft DAWN into space and how it uses an ion propulsion system to move which is much better than normal rockets. The sheet said that it was going to the asteriods Ceres and ... (i forget the other one) to see what the conditions early in the solar system were like. ION PROPULSION ROCKETS ??? Was the sheet true or not ? It certainly looked authentic, but why wasnt there anything about this in the papers ? The new propulsion system looks like the stuff from science fiction o_O.
Well, the rocket apparently works by ionising Xenon gas and accelerating it with a electric field, and due to Newtons third law of motion, accerates the rocket in the opposite direction.
