Launching from the moon Lab

During this lab, Cecilia, Gillian and I tried to get materials from the ground to the wall. We tried using the cardboard tube and we taped th lego sticks and three bllons to it. We tried to launch it once, but it did not make it off the ground. We spent 277,000 dollars on our one launch that failed. It surprised me how much force it took just to lift the cardboard tube off the ground. It felt light to me, lifting it, but the air didn't come out of the balloons very fast.

This related to Newton's third law because we were trying to pull alot of weight (as in force due to gravity) and we didn't have enough force pushing down to actually push us up and overcome that weight. The earth is alot more massive than us, so we (or our rocket thing) will move if we have enough force, but in our lab, we weren't able to create enough.

It made me really amazed at how much power rocket engines have, and how much power airplane engines have. I think this will be very useful during M2M because I'm pretty sure we have to either launch off earth or launch off Mars and apparently it takes a TON of force to do that!!!
