Why do you think they had to change the design? It is time to brainstorm YOUR ideas and compare with others.

The bouncing went on for forever, and it could've deflated too early. It was also probably pretty difficult to determine where it would end up, and it could've accidentally ended up in a dangerous place for the rover and gotten messed up.]]> 2020-10-06 14:43:34 UTC https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/806938394 https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/806955676 The bouncy design was a very cool way to go about it, however the first one is definitely more safe and cautious. ]]> 2020-10-06 14:47:28 UTC https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/806955676 https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/806957079 The curiosity landing was smooth and was lowered on a rope while the other rover bounced until it eventually stopped. They probably had to change the design because landing spot was inaccurate and there could have been more accidents with the balloons. ]]> 2020-10-06 14:47:48 UTC https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/806957079 https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/807003100 I think the landing of the Curiosity was very smooth but it also took a lot more precision and it had more mathematical components. The one with the bubbles was a lot more fun and I'm surprised it worked. It was a very creative solution. ]]> 2020-10-06 14:58:01 UTC https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/807003100 https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/807007475 With the bubble design, the consistency of the landing would not be as precise as the sky crane method even if the chance of failure is higher. The sky crane is more precise as you know more where exactly you will land whereas with the bubble you are at the mercy of the terrain. weather, and how it will bounce.]]> 2020-10-06 14:58:57 UTC https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/807007475 https://padlet.com/barnesengineering123/8uxa9h0clvg3/wish/815025608 The first Curiosity design and lading was more precise ans smoother than the bubble Curiosity the bubbles was more freely dropped and didn't have a set landing.
