Spacecraft and their missions are given descriptive, sometimes technical names, by scientists, engineers and administrators involved. Space agencies sometimes open the naming up to the public or to school children in the form of essay contests.
The entry from Ms. Nina DiMauro's class at Emily Dickinson Elementary School in Bozeman, Montana suggesting Ebb and Flow for the twin spacecraft was chosen from entries from 900 classrooms in 45 states. Maria Zuber, principal investigator on the mission commented on the student's research before selecting the names and its appropriateness for a mission measuring gravity. [1]
The name Sojourner was chosen for the Mars Pathfinder rover after a year-long, worldwide competition in which students up to 18 years old were invited to select a heroine and submit an essay about her historical accomplishments. The students were asked to address in their essays how a planetary rover named for their heroine would translate these accomplishments to the Martian environment. Initiated in March 1994 by The Planetary Society of Pasadena, California, in cooperation with NASA's Jet Propulsion Laboratory (JPL), the contest got under way with an announcement in the January 1995 issue of the National Science Teachers Association's magazine Science and Children, circulated to 20,000 teachers and schools across the nation. [2] The winning essay suggested naming the rover for Sojourner Truth was selected from among 3500 essays in a NASA/JPL sponsored contest on a heroine and her accomplishments. The essay selected was by then 12 year old Valerie Ambroise of Bridgeport, CT. The second place prize winner was Deepti Rohatgi, 18, of Rockville, MD, who suggested Marie Curie. Other popular suggestions included Sacajewea and Amelia Earhart. [3]
During development and construction, the rovers were known as MER-1 (Opportunity) and MER-2 (Spirit). Internally, NASA also uses the mission designations MER-A (Spirit) and MER-B (Opportunity) based on the order of landing on Mars (Spirit first then Opportunity). The rovers were named through a student essay competition sponsored by NASA, the Planetary Society and Lego. The winning entry was by Sofi Collis, a third-grade Russian-American student from Arizona, who named both rovers. [4]
I used to live in an orphanage. It was dark and cold and lonely. At night, I looked up at the sparkly sky and felt better. I dreamed I could fly there. In America, I can make all my dreams come true. Thank you for the 'Spirit' and the 'Opportunity.'
— Sofi Collis, age 9
The mission is known as the Mars Science Laboratory. The rover vehicle was named through an essay contest. Finalist names were ranked by the public between March 23–29, 2009 from among Adventure, Amelia, Journey, Perception, Pursuit, Sunrise, Vision, Wonder, and Curiosity. [5] through a public poll on the NASA website. [6] On May 27, 2009, the winning name was announced to be Curiosity from the winning essay by Clara Ma, then a sixth-grader from Kansas. [6] [7]
Curiosity is the passion that drives us through our everyday lives. We have become explorers and scientists with our need to ask questions and to wonder.
— Clara Ma, NASA/JPL Name the Rover contest
The working name of "space shuttle" was used throughout the program and spacecraft's development and construction. However, Peter Flanigan, Assistant to the President and Assistant to the President for International Economic Affairs to then President Nixon, expressed concern that the word "shuttle" brought to mind 2nd class travel and suggested instead words like "Space Clipper", "Pegasus", and "Starlighter." [8] Shortly after Nixon cemented the "space shuttle" program name in a January 1972 memo announcing the program would proceed. [9]
Originally to be named Constitution and unveiled on Constitution Day, September 17, 1976, a letter-writing campaign by Trekkies to then President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the television show Star Trek . Although Ford did not mention the campaign, instead saying he was "partial to the name" Enterprise, he directed NASA officials to change the name. [10] [11]
Columbia was named for the historical poetic name for the United States of America, like the explorer ship of Captain Robert Gray and the Command Module of Apollo 11, the first crewed landing on another celestial body. [12]
Challenger was named after HMS Challenger, a British corvette that was the command ship for the Challenger Expedition, a pioneering global marine research expedition undertaken from 1872 through 1876. The Apollo 17 Lunar Module, which landed on the Moon in 1972, was also named Challenger.
The name Discovery was chosen to carry on a tradition based on ships of exploration, primarily HMS Discovery, one of the ships commanded by Captain James Cook during his third and final major voyage from 1776 to 1779, and Henry Hudson's Discovery, which was used in 1610–1611 to explore Hudson Bay and search for a Northwest Passage. Other ships bearing the name have included HMS Discovery of the 1875–1876 British Arctic Expedition to the North Pole, and RRS Discovery, which carried the 1901–1904 Discovery Expedition to Antarctica, led by Captain Scott.
Atlantis is named after RV Atlantis, a two-masted sailing ship that operated as the primary research vessel for the Woods Hole Oceanographic Institution from 1930 to 1966.
The competition began in 1988 and the winning name was announced on May 10, 1989. Contest guidelines had students select a name based on an exploratory or research sea vessel, HMS Endeavour was the overwhelming selection among the 6,154. The Apollo 15 Command Module was also named Endeavour [13]
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by Caltech researchers, the laboratory is now owned and sponsored by NASA and administered and managed by the California Institute of Technology.
2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million. Its mission is to use spectrometers and a thermal imager to detect evidence of past or present water and ice, as well as study the planet's geology and radiation environment. The data Odyssey obtains is intended to help answer the question of whether life once existed on Mars and create a risk-assessment of the radiation that future astronauts on Mars might experience. It also acts as a relay for communications between the Curiosity rover, and previously the Mars Exploration Rovers and Phoenix lander, to Earth. The mission was named as a tribute to Arthur C. Clarke, evoking the name of his and Stanley Kubrick's 1968 film 2001: A Space Odyssey.
Mars Pathfinder was an American robotic spacecraft that landed a base station with a roving probe on Mars in 1997. It consisted of a lander, renamed the Carl Sagan Memorial Station, and a lightweight, 10.6 kg (23 lb) wheeled robotic Mars rover named Sojourner, the first rover to operate outside the Earth–Moon system.
Spirit, also known as MER-A or MER-2, is a Mars robotic rover, active from 2004 to 2010. Spirit was operational on Mars for 2208 sols or 3.3 Martian years. It was one of two rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL). Spirit landed successfully within the impact crater Gusev on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), which landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover got stuck in a "sand trap" in late 2009 at an angle that hampered recharging of its batteries; its last communication with Earth was on March 22, 2010.
Opportunity, also known as MER-B or MER-1, and nicknamed Oppy, is a robotic rover that was active on Mars from 2004 until 2018. Opportunity was operational on Mars for 5111 sols. Launched on July 7, 2003, as part of NASA's Mars Exploration Rover program, it landed in Meridiani Planum on January 25, 2004, three weeks after its twin, Spirit (MER-A), touched down on the other side of the planet. With a planned 90-sol duration of activity, Spirit functioned until it got stuck in 2009 and ceased communications in 2010, while Opportunity was able to stay operational for 5111 sols after landing, maintaining its power and key systems through continual recharging of its batteries using solar power, and hibernating during events such as dust storms to save power. This careful operation allowed Opportunity to operate for 57 times its designed lifespan, exceeding the initial plan by 14 years, 47 days. By June 10, 2018, when it last contacted NASA, the rover had traveled a distance of 45.16 kilometers.
A Mars rover is a remote-controlled motor vehicle designed to travel on the surface of Mars. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very remote robotic vehicle control. They serve a different purpose than orbital spacecraft like Mars Reconnaissance Orbiter. A more recent development is the Mars helicopter.
The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions, with some failing before their observations could begin. Some missions have been met with unexpected success, such as the twin Mars Exploration Rovers, Spirit and Opportunity, which operated for years beyond their specification.
The Discovery Program is a series of Solar System exploration missions funded by the U.S. National Aeronautics and Space Administration (NASA) through its Planetary Missions Program Office. The cost of each mission is capped at a lower level than missions from NASA's New Frontiers or Flagship Programs. As a result, Discovery missions tend to be more focused on a specific scientific goal rather than serving a general purpose.
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. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a human mission to Mars. The rover carries a variety of scientific instruments designed by an international team.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.
Endeavour is an impact crater located in the Meridiani Planum extraterrestrial plain within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. Endeavour is about 22 kilometers (14 mi) in diameter. Using Mars Reconnaissance Orbiter data, phyllosilicate-bearing outcrops have been detected along its rim. These minerals may have formed under wet conditions in a low-acidic environment during the early history of Mars. There are raised rim segments to the north, east, and southwest. The rim has become worn, rounded and degraded, with infilling of plains material in a manner similar to the Victoria crater.
Curiosity is a car-sized Mars rover exploring Gale crater and Mount Sharp on Mars as part of NASA's Mars Science Laboratory (MSL) mission. Curiosity was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover's touchdown target after a 560 million km (350 million mi) journey.
Mars 2020 is a NASA mission that includes the rover Perseverance, the now-retired small robotic helicopter Ingenuity, and associated delivery systems, as part of the Mars Exploration Program. Mars 2020 was launched on an Atlas V rocket at 11:50:01 UTC on July 30, 2020, and landed in the Martian crater Jezero on February 18, 2021, with confirmation received at 20:55 UTC. On March 5, 2021, NASA named the landing site Octavia E. Butler Landing. As of 17 November 2024, Perseverance has been on Mars for 1332 sols. Ingenuity operated on Mars for 1042 sols before sustaining serious damage to its rotor blades, possibly all four, causing NASA to retire the craft on January 25, 2024.
