What material, size, what choice of line, who worked on designing/developing it, & lastly who the hell is going to pack that? I personally wouldn't want to be responsible for a $2.5 billion dollar project to crash and burn lol Can't even imagine the forces being exerted upon opening with 65,000lbs of force traveling at 1,000 mphFor info regarding lift ticket prices all around the world check out http://www.jumpticketprices.com/dropzones.asp Quote Share this post Link to post Share on other sites

dthames 0 #4 July 1, 2012 QuoteI hope this is a joke. Rube Goldberg himself couldn't have come up with a goofier idea. It is expensive, in terms of weight, to slow and land with 100% rocket power. The air is too thin to slow enough for a soft landing with a reasonable size parachute. So, this is not a joke, it is building on the success the past 4 Mars landings.Instructor quote, “What's weird is that you're older than my dad!” Quote Share this post Link to post Share on other sites

JSE 1 #6 July 1, 2012 They don't want to land on the rockets because it would kick up dust that would land on or damage the rover. That seems odd to me. First, aren't there really bad sand storms on mars? If so its going to get dusty pretty soon anyway. Second, if that really is a problem, why not encase the rover in a shell that could be opened after a few hours when the dust settles? That seems like it would be cheaper/easier/lighter than hovering with rockets and lowering the rover, but who knows. Quote Share this post Link to post Share on other sites
ZigZagMarquis 8 #7 July 1, 2012 Isn't that thing getting ready to land on Mars here soon? I'm surprised they didn't send up a smaller rover with a proven landing system to try to video the landing of this thing... just in case... so they'd know what went wrong, if they crater Mars... again.

dthames 0 #8 July 2, 2012 On a Mars mission several years ago they discovered a parachute problem late in the game and scrambled to fix it. I recall seeing a documentary on it. This link is related to that series of events. http://marsrover.nasa.gov/spotlight/20040826.html Parachute design problems have existed for these spacecraft before. This new rover is a LOT larger. I am very interested in seeing how well they do. The last few have functioned well.Instructor quote, “What's weird is that you're older than my dad!” Quote Share this post Link to post Share on other sites

mchamp 1 #11 July 3, 2012 August 5th 1030pm PDT oh and here is a pic of their supersonic deploying parachute http://en.wikipedia.org/wiki/File:20090422MSLtestparachute.jpg More info: "The MSL parachute is the largest parachute ever made for an extraterrestrial mission with a diameter of nearly 16 meters (51 feet). The parachute uses 80 suspension lines and is made mostly of nylon except for a small disk of polyester. Both the MSL parachute and the MSL test parachute were made by Pioneer Aerospace." NASA/JPL-Caltech Taken from Wikipedia....Parachute descent: When the entry phase is complete and the capsule has slowed to Mach 2 and at about 10 km altitude, the heat shield will separate and fall away. The Mars Science Laboratory will then deploy a supersonic parachute,[102] as was done by previous landers such as Viking, Mars Pathfinder and the Mars Exploration Rovers. In March and April 2009, the parachute for the MSL was tested in the world's largest wind tunnel and passed flight-qualification testing.[106] The parachute has 80 suspension lines, is over 165 feet (50 meters) long, and is about 51 feet (16 meters) in diameter.[106] The parachute is capable of being deployed at Mach 2.2 and can generate up to 289 kN (65,000 pounds) of drag force in the Martian atmosphere.For info regarding lift ticket prices all around the world check out http://www.jumpticketprices.com/dropzones.asp Quote Share this post Link to post Share on other sites

jinlee 0 #15 August 5, 2012 Mars Odyssey is going to capture the deployment and descent to landing in real time. Hopefully it lands successfully. If it fails. I wonder what the data would be based on it's kinetic energy equivalent were Curiosity to impact Mars at an extreme speed. Due to it's weight & speed I believe the explosion would be significant. Were it to not separate from it's heat-shield and have no parachute deployment. Quote Share this post Link to post Share on other sites

AggieDave 6 #22 August 8, 2012 Apparently they were having problems with the 2-stage opening. They eventually changed to a ridiculously small PC made of ZP on the advice of the canopy manufacture, but the canopy still opened in a 1 really hard stage. The canopy manufacture was then suggesting to deploy with more forward speed, but it was hard to accomplish in the Martian atmosphere, so they made do with what they had until they could buy a canopy from another manufacture.
