Mars Exploration Rover

Mars Exploration RoversMars Exploration Rover MissionMER
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.
It began in 2003 with the launch of the two rovers: MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004.

Due to the planetary 2018 dust storm on Mars, Opportunity ceased communications on June 10 and entered hibernation on June 12, 2018.
Opportunity is a robotic rover that was active on the planet Mars from 2004 to 2018.

In 2004, Meridiani Planum was the landing site for the second of NASA's two Mars Exploration Rovers, named Opportunity.

Heat Shield Rock

Mission highlights included the initial 90-sol mission, finding extramartian meteorites such as Heat Shield Rock (Meridiani Planum meteorite), and over two years of exploring and studying Victoria crater.
Heat Shield Rock is a basketball-sized iron-nickel meteorite found on Mars by the Mars rover Opportunity in January 2005.

Opportunity, also known as MER-B (Mars Exploration Rover – B) or MER-1, and nicknamed "Oppy", is a robotic rover that was active on Mars from 2004 until the middle of 2018.
Clouds of water-ice were photographed by the Opportunity rover in 2004.

Endurance (crater)

Following this, it was directed to travel across the surface of Mars to investigate another crater site, Endurance crater, which it investigated from June to December 2004.
This crater was visited by the Opportunity rover from May until December 2004.

Mars Reconnaissance Orbiter

MROCTXCTX (camera)
The Mars Exploration Rovers were to travel across the Martian surface and perform periodic geologic analyses to determine if water ever existed on Mars as well as the types of minerals available, as well as to corroborate data taken by the Mars Reconnaissance Orbiter.
When MRO entered orbit, it joined five other active spacecraft that were either in orbit or on the planet's surface: Mars Global Surveyor, Mars Express, 2001 Mars Odyssey, and the two Mars Exploration Rovers (Spirit and Opportunity).

Eagle (Meridiani Planum crater)

From its initial landing, by chance, into an impact crater amidst an otherwise generally flat plain, Opportunity successfully investigated regolith and rock samples and took panoramic photos of its landing site.
The Opportunity rover came to rest inside Eagle crater when it landed in 2004.

Endeavour (crater)

Endeavour craterEndeavour
The rover survived moderate dust storms and in 2011 reached Endeavour crater, which has been described as a "second landing site".
The Mars Exploration Rover-B Opportunity began travelling toward this crater in August 2008, with the rim coming into sight on March 7, 2009, and arriving at the edge on August 9, 2011.

Erebus (crater)

Erebus craterErebus
Opportunity was directed to proceed in a southerly direction to Erebus crater, a large, shallow, partially buried crater and a stopover on the way south towards Victoria crater, between October 2005 and March 2006.
Erebus is a crater lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars, this extraterrestrial geological feature was visited by the Opportunity rover on the way to the much larger crater Victoria.

Victoria (crater)

This crater was first visited by the Mars Exploration Rover Opportunity.

Water on Mars

waterliquid waterunderground ice
Life, as we understand it, requires water, so the history of water on Mars is critical to finding out if the Martian environment was ever conducive to life. Opportunity has provided substantial evidence in support of the mission's primary scientific goals: to search for and characterize a wide range of rocks and regolith that hold clues to past water activity on Mars.
On January 24, 2014, NASA reported that current studies on Mars by the Curiosity and Opportunity rovers will be searching for evidence of ancient life, including a biosphere based on autotrophic, chemotrophic and/or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments (plains related to ancient rivers or lakes) that may have been habitable.

Rover (space exploration)

Opportunity, also known as MER-B (Mars Exploration Rover – B) or MER-1, and nicknamed "Oppy", is a robotic rover that was active on Mars from 2004 until the middle of 2018.
It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), landed on the other side of the planet.

Solander Point

In May 2013 the rover was heading south to a hill named Solander Point.
Solander Point was visited in 2013 by the Mars Exploration Rover-B Opportunity, a robotic rover that has been active on Mars since 2004.

Panoramic Camera (Pancam)Pancam camera
Each Pancam is one of two electronic stereo cameras on Mars Exploration Rovers Spirit and Opportunity.

ICER

The cameras produce 1024-pixel by 1024-pixel images, the data is compressed with ICER, stored, and transmitted later.
The Mars Exploration Rovers “Spirit” (MER-A) and “Opportunity” (MER-B) both use ICER.

Hazcam

Hazcams (short for hazard avoidance cameras) are photographic cameras mounted on the front and rear of NASA's Spirit, Opportunity and Curiosity rover missions to Mars and on the lower front portion of Chinese Yutu rover mission to the Moon.

Hematite

Its sampling allowed NASA scientists to make hypotheses concerning the presence of hematite and past presence of water on the surface of Mars.
In-situ investigations by the Opportunity rover showed a significant amount of hematite, much of it in the form of small spherules that were informally named "blueberries" by the science team.

39382 Opportunity

Honoring Opportunity's great contribution to the exploration of Mars, an asteroid was named Opportunity: 39382 Opportunity.
Discovered during the Palomar–Leiden survey at Palomar Observatory in 1960, it was named for NASA's Opportunity Mars rover.

Opportunity has provided substantial evidence in support of the mission's primary scientific goals: to search for and characterize a wide range of rocks and regolith that hold clues to past water activity on Mars.
Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity.

As NASA ended their attempts to contact the rover, the last data sent was the song "I'll Be Seeing You" performed by Billie Holiday.
Billie Holiday's 1944 recording of the song was the final transmission sent by NASA to the Opportunity rover on Mars when its mission ended on 13 February 2019.
