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. This was the first planetary mission to use precision landing techniques.  The sky crane concept had never been used in missions before.. Six senior members of the Curiosity team presented a news conference a few hours after landing, they were: John Grunsfeld, NASA associate administrator; Charles Elachi, director, JPL; Peter Theisinger, MSL project manager; Richard Cook, MSL deputy project manager; Adam Steltzner, MSL entry, descent and landing (EDL) lead; and John Grotzinger, MSL project scientist.  This location is near the mountain Aeolis Mons (a.k.a. The target landing site location was an elliptical area 20 by 7 km (12.4 by 4.3 mi). See the complete release schedule below. Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012. In some systems, insulating blankets kept sensitive science instruments warmer than the near-absolute zero temperature of space. It has tools including 17 cameras, a laser to vaporize and study small pinpoint spots of rocks at a distance, and a drill to collect powdered rock samples.

Truitt, through Geology Assistant Professor Mark Salvatore, is part of the research team on the latest mission to the Red Planet: the Mars Science Laboratory (MSL) Curiosity rover, the first nuclear powered, Humvee-sized robotic vehicle on Mars. Cape Canaveral Air Force Station, Florida, Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASA’s Science Mission Directorate. 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. With the Mars Science Laboratory—a rover called Curiosity—safely installed in its spacecraft, the Mars Science Laboratory mission set out for the red planet on November 26, 2011, with a projected arrival at Mars on August 5, 2012 PDT. , The Mars Science Laboratory mission is part of NASA's Mars Exploration Program, a long-term effort for the robotic exploration of Mars that is managed by the Jet Propulsion Laboratory of California Institute of Technology. , 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. Mars Science Laboratory arrived at Mars through technological innovations that tested a completely new landing method. The Mars Science Laboratory (MSL) is a NASA mission to land and control a rover named Curiosity on the surface of the planet Mars. Learn more about the agency's next Red Planet mission during a live event on June 17. Instead, Curiosity was set down on the Martian surface using a new high-accuracy entry, descent, and landing (EDL) system that was part of the MSL spacecraft descent stage. Part of NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. , MSL launched on an Atlas V rocket from Cape Canaveral on November 26, 2011. Operational since arrival at Mars in 2012. Curiosity rover has a mass of 899 kg (1,982 lb), can travel up to 90 m (300 ft) per hour on its six-wheeled rocker-bogie system, is powered by a multi-mission radioisotope thermoelectric generator (MMRTG), and communicates in both X band and UHF bands. 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. Curiosity's ongoing mission is to study the ancient habitability and the potential for life on Mars.  On May 27, 2009, the winning name was announced to be Curiosity. This would have required long landing legs that would need to have significant width to keep the center of gravity low. It is scheduled to launch next week. Langley Research Center conducts Earth science research to support NASA's mission. , The first and second stages, along with the solid rocket motors, were stacked on October 9, 2011 near the launch pad. Curiosity's first color image of the Martian landscape (August 6, 2012). MSL – Entry, Descent & Landing (EDL) – Description. Mars Science Laboratory (MSL) Curiosity, Mars mission. The Mars Science Laboratory will begin surface operations soon after landing in early August 2012 and continue for at least one Mars year (approximately two Earth years). LRC scientists and … The MSL mission has four scientific goals: Determine the landing site's habitability including the role of water, the study of the climate and the geology of Mars. The overall objectives include investigating Mars' habitability, studying its climate and geology, and co MSL is focused on determining the past habitability of Mars and is directly relevant to the goals of astrobiology. The rover was folded up within an aeroshell that protected it during the travel through space and during the atmospheric entry at Mars. Despite its late hour, particularly on the east coast of the United States where it was 1:31 a.m., the landing generated significant public interest. It hunts for special rocks that formed in water and/or have signs of organics. The parachute has 80 suspension lines, is over 50 m (160 ft) long, and is about 16 m (52 ft) in diameter.  The Mars Reconnaissance Orbiter team were able to acquire an image of the MSL descending under the parachute..  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. , 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 parachute deployed, as was done by previous landers such as Viking, Mars Pathfinder and the Mars Exploration Rovers. The ninth will be the first that includes a roundtrip ticket in its flight plan.  The heat shield is made of phenolic impregnated carbon ablator (PICA). Curiosity: The Next Mars Rover. Goal: Determine if Mars was ever able to support microbial life. , During cruise, eight thrusters arranged in two clusters were used as actuators to control spin rate and perform axial or lateral trajectory correction maneuvers.  Information was sent to mission controllers via two X-band antennas. If a particular surface is of interest, Curiosity can vaporize a small portion of it with an infrared laser and examine the resulting spectra signature to query the rock's elemental composition. The mission is planned to operate on Mars over at least a full martian year (687 Earth days).  The ejectable balance masses shift the capsule center of mass enabling generation of a lift vector during the atmospheric phase. It is also useful preparation for a future human mission to Mars. 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. A fourth landing site workshop was held in late September 2010, and the fifth and final workshop May 16–18, 2011. For the surface rover, see, Robotic mission that deployed the Curiosity rover to Mars in 2012, Missions are ordered by launch date. Faced with these challenges, the MSL engineers came up with a novel alternative solution: the sky crane. To contribute to these goals, MSL has eight main scientific objectives:, About one year into the surface mission, and having assessed that ancient Mars could have been hospitable to microbial life, the MSL mission objectives evolved to developing predictive models for the preservation process of organic compounds and biomolecules; a branch of paleontology called taphonomy. This capability helped remove some of the uncertainties of landing hazards that might be present in larger landing ellipses.  In addition to streaming and traditional video viewing, JPL made Eyes on the Solar System, a three-dimensional real time simulation of entry, descent and landing based on real data. A primary goal when selecting the landing site was to identify a particular geologic environment, or set of environments, that would support microbial life. After the rover touched down, it waited two seconds to confirm that it was on solid ground by detecting the weight on the wheels and fired several pyros (small explosive devices) activating cable cutters on the bridle and umbilical cords to free itself from the descent stage. Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012.  By the end of the second workshop in late 2007, the list was reduced to six; in November 2008, project leaders at a third workshop reduced the list to these four landing sites:. Curiosity is about twice as long and five times as heavy as Spirit and Opportunity, and carries over ten times the mass of scientific instruments.. The Mars Science Laboratory (MSL) Curiosity was launched to Mars in late 2011 and landed in the Red Planet in early August of 2012. 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.  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.  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 4.5 m (15 ft) diameter heat shield, which is the largest heat shield ever flown in space, 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. Curiosity successfully landed in the Gale Crater at 05:17:57.3 UTC on August 6, 2012, and transmitted Hazcam images confirming orientation. Thermostats monitored temperatures and switched heating and cooling systems on or off as needed. , The spacecraft flight system had a mass at launch of 3,893 kg (8,583 lb), consisting of an Earth-Mars fueled cruise stage (539 kg (1,188 lb)), the entry-descent-landing (EDL) system (2,401 kg (5,293 lb) including 390 kg (860 lb) of landing propellant), and a 899 kg (1,982 lb) mobile rover with an integrated instrument package..  A radar altimeter measured altitude and velocity, feeding data to the rover's flight computer. 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 Red Planet's surface has been visited by eight NASA spacecraft. It also measures the chemical fingerprints present in different rocks and soils to determine their composition and history, especially their past interactions with water.  It would have needed to have engines high enough above the ground when landing not to form a dust cloud that could damage the rover's instruments.  It also has its own electric power system, consisting of a solar array and battery for providing continuous power. Planetary science professor Sushil Atreya, who helped conceive of the … 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.

Testing and design of components also began in late 2004, including Aerojet's designing of a monopropellant engine with the ability to throttle from 15–100 percent thrust with a fixed propellant inlet pressure. Over 60 landing sites were evaluated, and by July 2011 Gale crater was chosen. Curiosity reads this record by analyzing powdered samples drilled from rocks. It continues to explore the rock record from a time when Mars could have been home to microbial life. The car-sized rover is part of NASA's Mars Science Laboratory (MSL).  Although some previous missions have used airbags to cushion the shock of landing, Curiosity rover is too heavy for this to be an option. NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. The Mars Science Laboratory (MSL) mission—along with its rover, Curiosity—is part of NASA’s Mars Exploration Program. Curiosity's large size allows it to carry an advanced kit of 10 science instruments. At roughly 7.5 m (25 ft) below the descent stage the sky crane system slowed to a halt and the rover touched down. The plutonium could power Curiosity for well more than 100 years, although NASA's nominal mission is planned for 680 days. As the support and data cables unreeled, the rover's six motorized wheels snapped into position. But the UM-Dearborn sophomore’s messages are from NASA—about Mars exploration. The rover carries a variety of scientific instruments designed by an international team. The MSL successfully did the first-ever precision landing on Mars. The spacecraft descended on a parachute, then during the final seconds before landing, the landing system fired rockets to allow it to hover while a tether lowered Curiosity to the surface.  The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. Part of NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. Curiosity is the passion that drives us through our everyday lives. Gale Crater is the MSL landing site. NASA leadership and members of the mission will discuss the agency’s latest rover, which touches down on the Red Planet on Feb. 18. Curiosity explores Gale Crater and acquires rock, soil, and air samples for onboard analysis. Solar System and Beyond. The history of Martian climate and geology is written in the chemistry and structure of the rocks and soil.  The final landing place for the rover was less than 2.4 km (1.5 mi) from its target after a 563,270,400 km (350,000,000 mi) journey. NASA  The next month, NASA delayed the launch to late 2011 because of inadequate testing time. The Mars Science Laboratory mission includes the Curiosity rover, which landed in Gale Crater on Mars on August 6, 2012.
