NASA’s real-time portal for Mars exploration, featuring the latest news, images, and discoveries from the Red Planet.
After establishing that Mars once had significant amount of water on its surface, the Mars Science Laboratory (which includes the Curiosity rover) was sent to Mars to determine whether Mars had the right ingredients in the rocks to host life, signaling a shift to the next theme of “Explore Habitability”. We have become explorers and scientists with our need to ask questions and to wonder.Over 60 landing sites were evaluated, and by July 2011 Gale crater was chosen. They preferred a landing site with both morphologic and mineralogical evidence for past water. A primary goal when selecting the landing site was to identify a particular geologic environment, or set of environments, that would support microbial life. NASA's Curiosity rover left Earth in November 2011 and landed in August 2012. The landing location for the rover was less than 2.4 km (1.5 mi) from the center of the planned landing ellipse, after a 563,000,000 km (350,000,000 mi) journey.Ejected Heat Shield as the rover descended to the Martian surface (August 6, 2012 05:17 UTC). This capability helped remove some of the uncertainties of landing hazards that might be present in larger landing ellipses.The rover was folded up within an Much of the reduction of the landing precision error was accomplished by an entry guidance algorithm, derived from the algorithm used for guidance of the When the entry phase was complete and the capsule slowed to about 470 m/s (1,500 ft/s) at about 10 km (6.2 mi) altitude, the supersonic Following the parachute braking, at about 1.8 km (1.1 mi) altitude, still travelling at about 100 m/s (220 mph), the rover and descent stage dropped out of the aeroshell.For several reasons, a different landing system was chosen for MSL compared to previous Mars landers and rovers. The rover's computers function on The general analysis strategy begins with high resolution cameras to look for features of interest. the Mars Science Laboratory’s Curiosity rover on the planet Mars. The latest news, images and videos from NASA's car-sized rover exploring the red planet for evidence the planet could have once supported life. NASA needs another $82 million to complete the Mars Science Laboratory Curiosity.
The specialized landing sequence, which employed a giant parachute, a jet-controlled descent vehicle and a bungee-like apparatus called a "sky crane," was devised because tested landing techniques used during previous rover missions could not safely accommodate the much larger and heavier rover. NASA Science Mars Exploration Program. The interplanetary trip covered the distance of 352 million miles in 253 days.During cruise, eight thrusters arranged in two clusters were used as Landing a large mass on Mars is particularly challenging as the The entry-descent-landing (EDL) system differs from those used for other missions in that it does not require an interactive, ground-generated mission plan. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. Mars Science Laboratory Project Changes Respond to Cost Increases, Keep Mars Program On Track 09.17.07 In early June 2007, the Mars Science Laboratory project completed its project-wide Critical Design Review (CDR), which marks the completion of the project's design phase and transition into the build up of flight hardware. The If a particular surface is of interest, The Mars Science Laboratory was recommended by United States National Research Council Decadal Survey committee as the top priority middle-class Mars mission in 2003.By November 2008 most hardware and software development was complete, and testing continued.Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity)Curiosity is the passion that drives us through our everyday lives. The cost of NASA's next Mars rover has hit nearly $2.5 billion. Furthermore, a site with spectra indicating multiple Engineering constraints called for a landing site less than 45° from the Martian equator, and less than 1 km above the reference A fourth landing site workshop was held in late September 2010,The first and second stages, along with the solid rocket motors, were stacked on October 9, 2011 near the launch pad.The cruise stage carried the MSL spacecraft through the void of space and delivered it to Mars.
