It launched November 26, 2011 and landed on Mars at 10:32 p.m. PDT on Aug. 5, 2012 (1:32 a.m. EDT on Aug. 6, 2012). Langley Research Center conducts Earth science research to support NASA's mission. The mission is planned to operate on Mars over at least a full martian year (687 Earth days). The history of Martian climate and geology is written in the chemistry and structure of the rocks and soil. [17][18] The rover mission is set to explore for at least 687 Earth days (1 Martian year) over a range of 5 by 20 km (3.1 by 12.4 mi). A legged lander would have also required ramps so the rover could drive down to the surface, which would have incurred extra risk to the mission on the chance rocks or tilt would prevent Curiosity from being able to drive off the lander successfully. In order for the aeroshell to have lift, its center of mass is offset from the axial centerline that results in an off-center trim angle in atmospheric flight. Langley Research Center supported NASA's mission by designing a spacecraft for a Mars landing. Within the first eight months of a 23-month primary mission, Curiosity met its major objective of finding evidence of a past environment well suited to supporting … This ability to change the pointing of the direction of lift allowed the spacecraft to react to the ambient environment, and steer toward the landing zone. Meanwhile, the rover transformed from its stowed flight configuration to a landing configuration while being lowered beneath the descent stage by the "sky crane" system. This is accomplished by a series of ejectable ballast masses consisting of two 75 kg (165 lb) tungsten weights that were jettisoned minutes before atmospheric entry. It is also useful preparation for a future human mission to Mars. One of the biggest steps in space exploration, the Mars Science Laboratory (MSL) named Curiosity was launched today with an Atlas V 541 vehicle and it is now on its way to Mars. LRC scientists and … The mass of this EDL system, including parachute, sky crane, fuel and aeroshell, is 2,401 kg (5,293 lb). The Mars Science Laboratory (MSL) rover, Curiosity, landed on Mars and began operations on August 6, 2012. A legged lander approach would have caused several design problems. by IKE 26-Nov-2011 17:44. It continues to explore the rock record from a time when Mars could have been home to microbial life. The MSL was launched on November 26, 2011. Upon reaching Mars, the spacecraft stopped spinning and a cable cutter separated the cruise stage from the aeroshell. The rover carries a variety of scientific instruments designed by an international team. The MSL successfully did the first-ever precision landing on Mars.

In the event, MSL achieved a landing 2.4 km (1.5 mi) east and 400 m (1,300 ft) north of the center of the target. Full Image Details Operational since arrival at Mars in 2012. The Mars Science Laboratory and its rover centerpiece, Curiosity, is the most ambitious Mars mission yet flown by NASA. Below is a University of Michigan video showing an overview of the Mars Science Laboratory mission, including the "7 minutes of terror" that NASA coined to describe the unprecedented landing plan designed for the mission. It is fit to climb over knee-high obstacles and travels about 100 feet (30 meters) per hour, depending on instrument activity, the terrain, and visibility its cameras have of the path ahead. One minute after separation from the cruise stage thrusters on the aeroshell fired to cancel out the spacecraft's 2-rpm rotation and achieved an orientation with the heat shield facing Mars in preparation for Atmospheric entry. The steady flow of electrical power enhanced the science payload capability and permitted consideration of landing sites at a greater range of latitudes than was possible on previous rovers. The 4.5 m (15 ft) diameter heat shield, which is the largest heat shield ever flown in space,[139] reduced the velocity of the spacecraft by ablation against the Martian atmosphere, from the atmospheric interface velocity of approximately 5.8 km/s (3.6 mi/s) down to approximately 470 m/s (1,500 ft/s), where parachute deployment was possible about four minutes later. The Mars Exploration Program is a long-term program focusing on the robotic exploration of the red planet. [129] Information was sent to mission controllers via two X-band antennas. Active, Ancient Organic Chemistry. [101] By the end of the second workshop in late 2007, the list was reduced to six;[102][103] in November 2008, project leaders at a third workshop reduced the list to these four landing sites:[104][105][106][107]. [121] The cruise stage has its own miniature propulsion system, consisting of eight thrusters using hydrazine fuel in two titanium tanks. [85][86][87] Eventually the costs for developing the rover reached $2.47 billion, that for a rover that initially had been classified as a medium-cost mission with a maximum budget of $650 million, yet NASA still had to ask for an additional $82 million to meet the planned November launch. For the surface rover, see, Robotic mission that deployed the Curiosity rover to Mars in 2012, Missions are ordered by launch date. Mars Science Laboratory: Entry, Descent, and Landing System Performance In 2010, the Mars Science Laboratory (MSL) mission will pioneer the next generation of robotic Entry, Descent, and Landing (EDL) systems, by delivering the largest and most capable rover to date to the surface of Mars. The spacecraft descended on … Cape Canaveral Air Force Station, Florida, Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASA’s Science Mission Directorate. [12] The rover carries a variety of scientific instruments designed by an international team. Since the initial size, velocity, density and impact angle of the hardware are known, it will provide information on impact processes on the Mars surface and atmospheric properties. The descent stage then flew away to a crash landing 650 m (2,100 ft) away. NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. Once landed, the applications were replaced with software for driving on the surface and performing scientific activities. [15][16] This location is near the mountain Aeolis Mons (a.k.a. Hematite, other iron oxides, sulfate minerals, silicate minerals, silica, and possibly chloride minerals were suggested as possible substrates for fossil preservation. 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. [97] Gale Crater's diameter is 154 km (96 mi). Curiosity descending under its parachute, as viewed by HiRISE (MRO) (August 6, 2012).
