Mars Rover Landings by Desiree Gillman https://padlet.com/desiree_gillman/v0j53g6lnaer Compare & Contrast the difference in the two ways NASA landed rovers on Mars. What do you notice that was different? Why do you think they had to change the design? Share your thoughts below. en-us 2018-08-16 00:55:29 UTC 2023-10-01 04:23:06 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Rocket.png I think that the mars rovers were different because the second one had a different shape and design. The landing was also different because the second one had a more rough landing. I think they had to change the design because the second one was more durable. They couldn't risk more very fragile equipment. https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280033314 -Jasmine Ameh]]> 2018-09-11 18:22:10 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280033314 They had to change the parachute design, because it was basically exploding. They ran many more tests to see if they could capture what was going on. After about 10 tries it happened. The parachute exploded. They found out the problem was that the parachute was turning inside out and then ripping apart. That was probably one of the things they had to change about the Mars Rover parachute. https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280033978 2018-09-11 18:23:15 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280033978 https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280035859     I notice that the difference of the two rover landings was that one of them was in a bunch of big bouncy balls and the other just used rockets and a parachute to get down.
    They had to change the design because the parachute broke apart.  They tryed to get it to break again but it kept going well. Finally, after more than 6  tries it finally broke again and they found that it was going inside-out and ripping. They had to change the parachute so that the rover could land safely.]]> 2018-09-11 18:26:08 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280035859 MARS ROVER https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280036099 They had to change the design because the first parachute design didn't slow the rover down as much as they wanted it to. The result was, they had to change the parachute. The parachute was just one of the problems.  The wheels had to be changed too.  They had to change the wheels because the landing wasn't good the first time around.  When they fixed both of those problems and the parachute worked out and the wheels worked out.  They changed their ideas to make their ideas better. Great job NASA! ]]> 2018-09-11 18:26:32 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280036099 They also redesigned curiosities wheels. They had to make sure that the rover was safe. They got they're inspiration from the bike. They noticed how it could sustain added weight. They decided to make large durable bike tires and put them on strong steel spokes to absorb the hit and the rest go to the suspension. That is another way that they changed the rovers https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280037359 2018-09-11 18:28:16 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280037359 https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280038184         I think the difference between the two rovers was that one had a different shape. Another difference was how they got the rover on mars.

They had to change the design because in one of the parachute tests it broke apart. They did not want this to happen when it truly count so they put up a lot of cameras and finally they got it and saw that it was folding and tearing. I think that is one thing they had to fix. ]]> 2018-09-11 18:29:29 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280038184 The mars rovers were different because one of them had a triangle shaped package and it exploded into a triangle shaped rover. The first one had wheels and it also did not let go of the string because the other one let go of the string. https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280039154 -audrey smith]]> 2018-09-11 18:30:55 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280039154 27nsun https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280039243 They had to change the way that they designed the parachute because it was tearing apart when they tested it.

The time it takes for the spacecraft to download new data is called 7 minutes of TERROR.During this period, scientists have know contact with the spacecraft until the rover is on the surface. Anything could go wrong

Curiosity has rockets and a 3 foot drop while the rover that landed in 2004 was a triangle that inflated into a cluster of big bouncy balls. But Curiostiy also had bigger risks, while the 2004 rover just had 1 risk (the balls popping). But Curiosity was overall better and more complex than the rover that landed in 2004.]]> 2018-09-12 13:03:36 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280316841 Mars Rover Landings https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280319472 The Curiosity was more complex than the first rover because the Curiosity was like a machine/mini car while the first rover was like a bouncy ball.

I think even when the same parachute stood up they knew there was a problem because mars atmosphere is 100 times thinner than earth´s atmosphere. Also, the rover was going really fast in the air.]]> 2018-09-12 13:08:56 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280320392 Mars Rovers https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280321505 I think NASA had to change the design because the parachute kept  ripping apart and this would make the rover crash to the ground witch would destroy the rover.

They are the same because they both used parachutes and both mars rovers were used to find information and explore mars. That is why both mars rovers are different and the same.]]> 2018-09-12 13:18:24 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280326173 The Problem With the Parachute https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280326580  People were testing the parachute in the mars mission and it ripped. The next time they tried they wanted it to rip again so they could see the problem.They put about 14 cameras' so they could catch the problem. Instead of it ripping again it worked just the way they would have liked it to, but that wasn't the case.they kept trying and trying until it ripped again! They were pretty happy that they had had got the footage on why it ripped! What happened was a piece of the parachute started getting air and it made it go inside out. That is what caused it to rip]]> 2018-09-12 13:19:06 UTC https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280326580 Mars Rover Landings https://padlet.com/desiree_gillman/v0j53g6lnaer/wish/280330557      The difference between the first landing process and the second landing process is that the first one used rocket boosters and the skycrane meneuver while the second process used a bouncy sheild that would protect the rover and the materials inside.

 again and again hoping to find out what happened to the parachute. After a long time they found the problem, the sides had crossed over and formed an air pocket.
