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. It continues to explore the rock record from a time when Mars could have been home to microbial life. ", "MSL Science Corner: Mars Descent Imager (MARDI)", "MSL Picture of the Day: T-27 Days: instruments: MARDI", "The Photo-Geek's Guide to Curiosity Rover's 17 Cameras", "Suggestion: Stop Improving – Why does every Mars mission have to be better than the last? In the attempts to meet the launch date, several instruments and a cache for samples were removed and other instruments and cameras were simplified to simplify testing and integration of the rover.  Difficult terrain was favored for finding evidence of livable conditions, but the rover must be able to safely reach the site and drive within it. Scheduled to land in August of 2012, the Mars Science Laboratory (MSL) Mission was initiated to explore the habitability of Mars.  The rover carries a variety of scientific instruments designed by an international team. A camera beneath the rover acquired about 5 frames per second (with resolution of 1600×1200 pixels) below 3.7 km (2.3 mi) during a period of about 2 minutes until the rover sensors confirmed successful landing.  After the parachute was deployed, the heat shield separated and fell away. Mars Science Laboratory arrived at Mars through technological innovations that tested a completely new landing method. 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 … Curiosity's large size allows it to carry an advanced kit of 10 science instruments. 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  The next month, NASA delayed the launch to late 2011 because of inadequate testing time. Under consideration to boost the Mars Science Laboratory is either the … 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. Curiosity carries the biggest, most advanced instruments for scientific studies ever sent to the Martian surface. Vaneeza Rupani's essay was chosen as the name for the small spacecraft, which will mark NASA's first attempt at powered flight on another planet. Furthermore, a site with spectra indicating multiple hydrated minerals was preferred; clay minerals and sulfate salts would constitute a rich site.  NASA named the rover landing site Bradbury Landing on sol 16, August 22, 2012. NASA leadership and members of the mission will discuss the agency’s latest rover, which touches down on the Red Planet on Feb. 18. 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 parachute has 80 suspension lines, is over 50 m (160 ft) long, and is about 16 m (52 ft) in diameter. MSL carried the Curiosity Rover, which landed in the Gale Crater in 2012. 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. Ejected Heat Shield as the rover descended to the Martian surface (August 6, 2012 05:17 UTC). The Entry, Descent and Landing Mission Phase – short: EDL – begins when the Mars Science Laboratory (MSL) has nearly completed its 567-Million Kilometer (352-Million Mile) Trip from Earth to Mars. For several reasons, a different landing system was chosen for MSL compared to previous Mars landers and rovers. Cape Canaveral Air Force Station, Florida, Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASA’s Science Mission Directorate. 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. Precision guided entry made use of onboard computing ability to steer itself toward the pre-determined landing site, improving landing accuracy from a range of hundreds of kilometers to 20 kilometers (12 mi). Curiosity was considered too heavy to use the airbag landing system as used on the Mars Pathfinder and Mars Exploration Rovers. The MSL successfully did the first-ever precision landing on Mars. The ninth will be the first that includes a roundtrip ticket in its flight plan. , 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.

The car-size rover is about as tall as a basketball player and uses a 7 foot-long arm to place tools close to rocks selected for study.  The NASA Launch Services Program coordinated the launch via the NASA Launch Services (NLS) I Contract. . Curiosity's ongoing mission is to study the ancient habitability and the potential for life on Mars. The target landing site location was an elliptical area 20 by 7 km (12.4 by 4.3 mi). As the support and data cables unreeled, the rover's six motorized wheels snapped into position. , Previous successful U.S. Mars rovers include Sojourner from the Mars Pathfinder mission and the Mars Exploration Rovers Spirit and Opportunity. The Mars Science Laboratory and its rover centerpiece, Curiosity, is the most ambitious Mars mission yet flown by NASA. , MSL was launched from Cape Canaveral Air Force Station Space Launch Complex 41 on November 26, 2011, at 15:02 UTC via the Atlas V 541 provided by United Launch Alliance. Upon reaching Mars, the spacecraft stopped spinning and a cable cutter separated the cruise stage from the aeroshell. MSL's debris field on August 17, 2012 (3-D versions: rover & parachute). 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. Operational since arrival at Mars in 2012. They preferred a landing site with both morphologic and mineralogical evidence for past water. Part of NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars.  On January 11, 2012, the spacecraft successfully refined its trajectory with a three-hour series of thruster-engine firings, advancing the rover's landing time by about 14 hours. It is also useful preparation for a future human mission to Mars. The spacecraft employed several systems in a precise order, with the entry, descent and landing sequence broken down into four parts—described below as the spaceflight events unfolded on August 6, 2012. Active, Ancient Organic Chemistry. 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 … If the specimen warrants further analysis, Curiosity can drill into the boulder and deliver a powdered sample to either the SAM or the CheMin analytical laboratories inside the rover. This would have required long landing legs that would need to have significant width to keep the center of gravity low. Curiosity set out to answer the question: Did Mars ever have the right environmental conditions to support small life forms called microbes? Awards. 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. 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. , Engineering constraints called for a landing site less than 45° from the Martian equator, and less than 1 km above the reference datum.  Although some previous missions have used airbags to cushion the shock of landing, Curiosity rover is too heavy for this to be an option. The Mars Science Laboratory (MSL), nicknamed Curiosity, is a large rover with the objective of exploring the martian environment as a former or current habitat for life.  The ejectable balance masses shift the capsule center of mass enabling generation of a lift vector during the atmospheric phase. The rover began its first drive on Mars Aug. 29, 2012. The total cost of the MSL project is about US$2.5 billion.

NASA Gale Crater is the MSL landing site.  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:. , Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity) through a public poll on the NASA website. The car-sized rover is part of NASA's Mars Science Laboratory (MSL). Mission Overview. If that signature intrigues, the rover will use its long arm to swing over a microscope and an X-ray spectrometer to take a closer look. , The cruise stage carried the MSL spacecraft through the void of space and delivered it to Mars.  It also has its own electric power system, consisting of a solar array and battery for providing continuous power.  Capable of being deployed at Mach 2.2, the parachute can generate up to 289 kN (65,000 lbf) of drag force in the Martian atmosphere. 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. The plutonium could power Curiosity for well more than 100 years, although NASA's nominal mission is planned for 680 days. Landed on Mars: Aug. 6, 2012. 3.2 million watched the landing live with most watching online instead of on television via NASA TV or cable news networks covering the event live. The overall objectives include investigating Mars' habitability, studying its climate and geology, and co 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.  Within Gale Crater is a mountain, named Aeolis Mons ("Mount Sharp"), of layered rocks, rising about 5.5 km (18,000 ft) above the crater floor, that Curiosity will investigate.  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.  A radar altimeter measured altitude and velocity, feeding data to the rover's flight computer. It is scheduled to launch next week.  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). For the surface rover, see, Robotic mission that deployed the Curiosity rover to Mars in 2012, Missions are ordered by launch date. As of 2012, the project suffered an 84 percent overrun. Goal: Determine if Mars was ever able to support microbial life. In some systems, insulating blankets kept sensitive science instruments warmer than the near-absolute zero temperature of space. Curiosity is the largest, most advanced rover sent to Mars thus far. The interplanetary trip covered the distance of 352 million miles in 253 days. 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.  Information was sent to mission controllers via two X-band antennas. , During cruise, eight thrusters arranged in two clusters were used as actuators to control spin rate and perform axial or lateral trajectory correction maneuvers. , The EDL phase of the MSL spaceflight mission to Mars took only seven minutes and unfolded automatically, as programmed by JPL engineers in advance, in a precise order, with the entry, descent and landing sequence occurring in four distinct event phases:.  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. The mission is planned to last at least one martian year (687 days). 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).  The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. This includes both modern environments as well as ancient environments recorded by the stratigraphic rock record preserved at the Gale crater landing site. Curiosity is the passion that drives us through our everyday lives.  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 sky crane concept had never been used in missions before.. (see the Mars Exploration Rover.) Each rocket thruster, called a Mars Lander Engine (MLE), produces 400 to 3,100 N (90 to 697 lbf) of thrust and were derived from those used on the Viking landers. 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).  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 descent stage then flew away to a crash landing 650 m (2,100 ft) away. 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.  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. NASA’s Mars Science Laboratory mission set down a large, mobile laboratory — the rover Curiosity — at Gale Crater, using precision landing technology that made one of Mars’ most intriguing regions a viable destination for the first time. Curiosity's first test drive ("Bradbury Landing") (August 22, 2012). Curiosity's first image after landing – The rover's wheel can be seen (August 6, 2012). It also measures the chemical fingerprints present in different rocks and soils to determine their composition and history, especially their past interactions with water. 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. View the latest news, images, and discoveries from the Red Planet. 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. See the complete release schedule below. Learn more about the agency's next Red Planet mission during a live event on June 17. Indeed, all are known to facilitate the preservation of fossil morphologies and molecules on Earth. Mars Science Laboratory Mission (MSL) is part of NASA’s Mars Exploration Program, a long-term effort targeting robotic exploration of Mars. Curiosity's landing site ("Bradbury Landing") viewed by HiRISE (MRO) (August 14, 2012). 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 first and second stages, along with the solid rocket motors, were stacked on October 9, 2011 near the launch pad. MSL – Entry, Descent & Landing (EDL) – Description. by IKE 26-Nov-2011 17:44.  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.  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. The generator provides greater mobility and flexibility in operating the rover regardless of season or sunlight.  This location is near the mountain Aeolis Mons (a.k.a. , 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), in the Aeolis Palus region of Gale Crater. Hematite, other iron oxides, sulfate minerals, silicate minerals, silica, and possibly chloride minerals were suggested as possible substrates for fossil preservation.  The heat shield is made of phenolic impregnated carbon ablator (PICA). The MSL was launched on November 26, 2011. The “mole,” a heat probe that traveled to Mars aboard NASA’s InSight lander, as it looked after hammering on Jan. 9, 2021, the 754th Martian day, or sol, of the mission. Ten minutes before atmospheric entry the aeroshell separated from the cruise stage that provided power, communications and propulsion during the long flight to Mars. The Mars Science Laboratory mission includes the Curiosity rover, which landed in Gale Crater on Mars on August 6, 2012.  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.  The cruise stage has its own miniature propulsion system, consisting of eight thrusters using hydrazine fuel in two titanium tanks. The main objective of the MSL mission is to "assess habitability" of both Mars' past and present environments 1.

Curiosity explores Gale Crater and acquires rock, soil, and air samples for onboard analysis. 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. The Mars Science Laboratory (MSL) is a NASA mission to land and control a rover named Curiosity on the surface of the planet Mars. After trying since Feb. 28, 2019, to bury the probe, the mission team called an end to their efforts. The overall scientific goal of the mission is to explore and quantitatively assess a local region on Mars’ surface as a potential habitat for life, past or present.
