This was the first planetary mission to use precision landing techniques. [26], 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.[1][27]. [91], Between March 23–29, 2009, the general public ranked nine finalist rover names (Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity)[92] through a public poll on the NASA website. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. . Over 60 landing sites were evaluated, and by July 2011 Gale crater was chosen. The Red Planet's surface has been visited by eight NASA spacecraft. [83][84] The next month, NASA delayed the launch to late 2011 because of inadequate testing time. It hunts for special rocks that formed in water and/or have signs of organics. 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). 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). [98] 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. Curiosity's landing site ("Bradbury Landing") viewed by HiRISE (MRO) (August 14, 2012). [141] After the parachute was deployed, the heat shield separated and fell away. The mission is planned to operate on Mars over at least a full martian year (687 Earth 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 … The name had been submitted in an essay contest by Clara Ma, a then sixth-grader from Kansas.[93][94][95]. The ninth will be the first that includes a roundtrip ticket in its flight plan. 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.

(see the Mars Exploration Rover.) We have become explorers and scientists with our need to ask questions and to wonder. NASA leadership and members of the mission will discuss the agency’s latest rover, which touches down on the Red Planet on Feb. 18. by IKE 26-Nov-2011 17:44. Mars. But the UM-Dearborn sophomore’s messages are from NASA—about Mars exploration. Landed on Mars: Aug. 6, 2012. Solar System and Beyond. MSL carried the Curiosity Rover, which landed in the Gale Crater in 2012. The spacecraft employed several systems in a precise order, with the entry, descent and landing sequence broken down into four parts[132][133]—described below as the spaceflight events unfolded on August 6, 2012. "Mount Sharp"). [148] The sky crane concept had never been used in missions before.[149]. [100] At the first MSL Landing Site workshop, 33 potential landing sites were identified. Langley Research Center supported NASA's mission by designing a spacecraft for a Mars landing. [99], Engineering constraints called for a landing site less than 45° from the Martian equator, and less than 1 km above the reference datum. 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. [158] According to NASA, an estimated 20,000 to 40,000 heat-resistant bacterial spores were on Curiosity at launch, and as much as 1,000 times that number may not have been counted.[159]. Planners looked for a site that could contribute to a wide variety of possible science objectives. [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. 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 rover carries a radioisotope power system that generates electricity from the heat of plutonium's radioactive decay. Upon reaching Mars, the spacecraft stopped spinning and a cable cutter separated the cruise stage from the aeroshell. [36] During the trip to Mars, VxWorks ran applications dedicated to the navigation and guidance phase of the mission, and also had a pre-programmed software sequence for handling the complexity of the entry-descent-landing.

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. [122], Landing a large mass on Mars is particularly challenging as the atmosphere is too thin for parachutes and aerobraking alone to be effective,[130] while remaining thick enough to create stability and impingement problems when decelerating with retrorockets. Curiosity is the passion that drives us through our everyday lives. Mars Science Laboratory Mission (MSL) is part of NASA’s Mars Exploration Program, a long-term effort targeting robotic exploration of Mars. The Mars Science Laboratory mission includes the Curiosity rover, which landed in Gale Crater on Mars on August 6, 2012. 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 [12] The rover carries a variety of scientific instruments designed by an international team. The overall objectives include investigating Mars' habitability, studying its climate and geology, and co For several reasons, a different landing system was chosen for MSL compared to previous Mars landers and rovers. The MSL was launched on November 26, 2011. NASA's Curiosity is the largest and most advanced rover ever sent to Mars. Despite its late hour, particularly on the east coast of the United States where it was 1:31 a.m.,[6] the landing generated significant public interest. [140][146][147] This system consists of a bridle lowering the rover on three nylon tethers and an electrical cable carrying information and power between the descent stage and rover. [157] NASA named the rover landing site Bradbury Landing on sol 16, August 22, 2012. This includes both modern environments as well as ancient environments recorded by the stratigraphic rock record preserved at the Gale crater landing site. Cape Canaveral Air Force Station, Florida, Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASA’s Science Mission Directorate. NASA [89] 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. Ten seconds after peak heating, that deceleration peaked out at 15 g.[138], 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 Apollo Command Modules returning to Earth in the Apollo program. The Mars Science Laboratory (MSL) is a NASA mission to land and control a rover named Curiosity on the surface of the planet Mars. [88], MSL launched on an Atlas V rocket from Cape Canaveral on November 26, 2011. [141] 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. [136] Steering was achieved by the combined use of thrusters and ejectable balance masses. The rover began its first drive on Mars Aug. 29, 2012. [93] On May 27, 2009, the winning name was announced to be Curiosity.

The target landing site location was an elliptical area 20 by 7 km (12.4 by 4.3 mi). 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). 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. Under consideration to boost the Mars Science Laboratory is either the … 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. Mars Science Laboratory is intended to be the first planetary mission to use precision landing techniques, steering itself toward the martian surface similar to the way the space shuttle controls its entry through Earth's upper atmosphere. For the surface rover, see, Robotic mission that deployed the Curiosity rover to Mars in 2012, Missions are ordered by launch date. 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. 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. 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. Curiosity: The Next Mars Rover. Furthermore, a site with spectra indicating multiple hydrated minerals was preferred; clay minerals and sulfate salts would constitute a rich site. MSL's debris field on August 17, 2012 (3-D versions: rover & parachute). The Mars Science Laboratory (MSL) mission—along with its rover, Curiosity—is part of NASA’s Mars Exploration Program. Faced with these challenges, the MSL engineers came up with a novel alternative solution: the sky crane. Earth science. [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. Curiosity's ongoing mission is to study the ancient habitability and the potential for life on Mars. [126], 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 Mars Science Laboratory and its rover centerpiece, Curiosity, is the most ambitious Mars mission yet flown by NASA. [122] It also has its own electric power system, consisting of a solar array and battery for providing continuous power. 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. 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. 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. The spacecraft descended on … [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). During the entire landing phase, the vehicle acts autonomously, based on pre-loaded software and parameters. 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 … [119] The NASA Launch Services Program coordinated the launch via the NASA Launch Services (NLS) I Contract. [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. The Mars Science Laboratory (MSL) rover, Curiosity, landed on Mars and began operations on August 6, 2012. [19], 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. Curiosity explores Gale Crater and acquires rock, soil, and air samples for onboard analysis. NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. 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. The main objective of the MSL mission is to "assess habitability" of both Mars' past and present environments 1. [80] NASA called for proposals for the rover's scientific instruments in April 2004,[81] and eight proposals were selected on December 14 of that year. Full Image Details One minute and 15 seconds after entry the heat shield experienced peak temperatures of up to 2,090 °C (3,790 °F) as atmospheric pressure converted kinetic energy into heat. [130] Although some previous missions have used airbags to cushion the shock of landing, Curiosity rover is too heavy for this to be an option. Curiosity is the largest, most advanced rover sent to Mars thus far. [117], 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. [138], 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,[140] as was done by previous landers such as Viking, Mars Pathfinder and the Mars Exploration Rovers. [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. View the latest news, images, and discoveries from the Red Planet. 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). [123][124] In December 2012, the debris field from the cruise stage was located by the Mars Reconnaissance Orbiter. MSL – Entry, Descent & Landing (EDL) – Description. This capability helped remove some of the uncertainties of landing hazards that might be present in larger landing ellipses. [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. [39] 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. 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. 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. [5][115], The first and second stages, along with the solid rocket motors, were stacked on October 9, 2011 near the launch pad. Curiosity is about twice as long and five times as heavy as Spirit and Opportunity,[22] and carries over ten times the mass of scientific instruments.[23]. [15][16] This location is near the mountain Aeolis Mons (a.k.a. The car-sized rover is part of NASA's Mars Science Laboratory (MSL). It is also useful preparation for a future human mission to Mars. Part of NASA's Mars Science Laboratory mission, Curiosity is the largest and most capable rover ever sent to Mars. [129] Information was sent to mission controllers via two X-band antennas. Mars Science Laboratory arrived at Mars through technological innovations that tested a completely new landing method. Early in its mission, Curiosity's scientific tools found chemical and mineral evidence of past habitable environments on Mars. [138] This guidance uses the lifting force experienced by the aeroshell to "fly out" any detected error in range and thereby arrive at the targeted landing site. [27][127][128] Along the way, the cruise stage performed four trajectory correction maneuvers to adjust the spacecraft's path toward its landing site.
