Earth science. 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). This electrical power source has already far exceeded its required operating lifespan on Mars' surface of at least one full Martian year (687 Earth days). Curiosity successfully landed in the Gale Crater at 05:17:57.3 UTC on August 6, 2012,[3][6][7][11] and transmitted Hazcam images confirming orientation. 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 mass of this EDL system, including parachute, sky crane, fuel and aeroshell, is 2,401 kg (5,293 lb). [138] The lift vector was controlled by four sets of two reaction control system (RCS) thrusters that produced approximately 500 N (110 lbf) of thrust per pair. [125], The MSL spacecraft departed Earth orbit and was inserted into a heliocentric Mars transfer orbit on November 26, 2011, shortly after launch, by the Centaur upper stage of the Atlas V launch vehicle. The Mars Science Laboratory (MSL) Curiosity was launched to Mars in late 2011 and landed in the Red Planet in early August of 2012. [11] Due to the Mars-Earth distance at the time of landing and the limited speed of radio signals, the landing was not registered on Earth for another 14 minutes. NASA Curiosity's ongoing mission is to study the ancient habitability and the potential for life on Mars. [122] A key task of the cruise stage was to control the temperature of all spacecraft systems and dissipate the heat generated by power sources, such as solar cells and motors, into space. [118] This two stage rocket includes a 3.8 m (12 ft) Common Core Booster (CCB) powered by one RD-180 engine, four solid rocket boosters (SRB), and one Centaur second stage with a 5 m (16 ft) diameter payload fairing. The Mars Science Laboratory mission includes the Curiosity rover, which landed in Gale Crater on Mars on August 6, 2012. The MSL successfully did the first-ever precision landing on Mars. [140] The descent stage is a platform above the rover with eight variable thrust monopropellant hydrazine rocket thrusters on arms extending around this platform to slow the descent. [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]. It continues to explore the rock record from a time when Mars could have been home to microbial life. After trying since Feb. 28, 2019, to bury the probe, the mission team called an end to their efforts. [97] Gale Crater's diameter is 154 km (96 mi). Key Findings: Conditions Once Fit for Ancient Life. Ten minutes before atmospheric entry the aeroshell separated from the cruise stage that provided power, communications and propulsion during the long flight to Mars. [82] At this point, cost overruns were approximately $400 million. The MSL was launched on November 26, 2011. The Mars Science Laboratory (MSL) mission—along with its rover, Curiosity—is part of NASA’s Mars Exploration Program. Active, Ancient Organic Chemistry. The history of Martian climate and geology is written in the chemistry and structure of the rocks and soil. Image courtesy of NASA/JPL-Caltech ANN ARBOR—Two University of Michigan planetary scientists are vital members of the science team of the Mars Science Laboratory, which will study whether the Red Planet was ever capable of harboring microbial life.

[13], MSL successfully carried out the most accurate Martian landing of any known spacecraft, hitting a small target landing ellipse of only 7 by 20 km (4.3 by 12.4 mi),[14] in the Aeolis Palus region of Gale Crater. Curiosity: The Next Mars Rover. The main objective of the MSL mission is to "assess habitability" of both Mars' past and present environments 1. [119] Prior to Centaur separation, the spacecraft was spin-stabilized at 2 rpm for attitude control during the 36,210 km/h (22,500 mph) cruise to Mars. The heat probe hasn’t been able to gain the friction it needs to dig, but the mission has been granted an extension to carry on with its other science. See the complete release schedule below.

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. [3][6][7][11] The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. [99], Engineering constraints called for a landing site less than 45° from the Martian equator, and less than 1 km above the reference datum. [113] On July 22, 2011, it was announced that Gale Crater had been selected as the landing site of the Mars Science Laboratory mission. This would have required long landing legs that would need to have significant width to keep the center of gravity low. Abstract: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 … Curiosity's first image after landing – The rover's wheel can be seen (August 6, 2012). The Mars Exploration Program is a long-term program focusing on the robotic exploration of the red planet. The Mars Science Laboratory (MSL) rover, Curiosity, landed on Mars and began operations on August 6, 2012. LAUNCH LOCATION The MSL was launched on November 26, 2011. Prior to parachute deployment the entry vehicle ejected more ballast mass consisting of six 25 kg (55 lb) tungsten weights such that the center of gravity offset was removed. A legged lander approach would have caused several design problems. MSL carried the Curiosity Rover, which landed in the Gale Crater in 2012. As the support and data cables unreeled, the rover's six motorized wheels snapped into position. The generator provides greater mobility and flexibility in operating the rover regardless of season or sunlight. Awards. Mars Science Laboratory Mission (MSL) is part of NASA’s Mars Exploration Program, a long-term effort targeting robotic exploration of Mars. The MSL spacecraft includes spaceflight-specific instruments, in addition to utilizing one of the rover instruments — Radiation assessment detector (RAD) — during the spaceflight transit to Mars. [81], By November 2008 most hardware and software development was complete, and testing continued. When MSL was launched, the program's director was Doug McCuistion of NASA's Planetary Science Division.[90]. Thermostats monitored temperatures and switched heating and cooling systems on or off as needed. [27] The EDL system was based on a Viking-derived aeroshell structure and propulsion system for a precision guided entry and soft landing, in contrasts with the airbag landings that were used in the mid-1990s by the Mars Pathfinder and Mars Exploration Rover missions. The mission is planned to last at least one martian year (687 days). Two other instruments will help engineers design systems for future human explorers to land and survive on Mars: The MEDLI2 (Mars Entry, Descent, and Landing Instrumentation 2) package is a next-generation version of what flew on the Mars Science Laboratory mission that delivered the Curiosity rover, while the MEDA (Mars Environmental Dynamics Analyzer) instrument suite provides … More details on Mars Science Laboratory Mars Science Laboratory Home Page Diagram of Mars Science Laboratory Investigations Chosen for Mars Science Laboratory - 14 December 2004 NASA Press Release 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.
