Perseverance rover on Mars (artist; 18 February 2021)
The Mars 2020 mission, consisting of the rover Perseverance and helicopter Ingenuity, was launched on July 30, 2020, and landed in Jezero crateronMars on February 18, 2021.[1] As of June 19, 2024, Perseverance has been on the planet for 1184 sols (1217 total days; 3 years, 122 days). Ingenuity operated for 1042 sols (1071 total days; 1 year, 341 days) until its rotor blades, possibly all four, were damaged during the landing of flight 72 on January 18, 2024, causing NASA to retire the craft.[2][3]
Current weather data on Mars is being monitored by the Curiosity rover and the Insight lander.[4][5] The Perseverance rover is also collecting weather data. (See the External links section)
December 4, 2012: Mars 2020 mission announced by NASA.
February 8–10, 2017: Workshop held to discuss eight proposed landing sites for the mission. The three sites chosen were Jezero crater, Northeastern Syrtis Major Planum, and Columbia Hills.
Landing and initial tests (February–May 2021)[edit]

After arriving on February 18, Perseverance focused on validating its systems. During this phase, it used its science instruments for the first time,[6] generated oxygen on Mars with MOXIE,[7] and deployed Ingenuity. Ingenuity began the technology demonstration phase of its mission, completing five flights before transitioning to the operations demonstration phase of its mission.

February 20, 2021: Perseverance records the first audio from the surface of another planet.[8]
March 4, 2021: Perseverance rover's first test drive.
April 8, 2021: NASA reported the first MEDA weather report on Mars: for 3–April 4, 2021, the high was "minus-7.6 degrees, and a low of minus-117.4 degrees ... [winds] gusting to ... 22 mph".[10]
April 22, 2021: Second flight test of Ingenuity[11]
April 25, 2021: Third flight test of Ingenuity.
April 30, 2021: Fourth flight test of Ingenuity.[12]
May 7, 2021: Fifth flight test of Ingenuity.[13] First one-way flight on Mars. Ingenuity's mission transitions from being a technology demonstration to being an operations demonstration.[14][15]
May 22, 2021: Sixth flight test of Ingenuity, first of the operations demonstration.[16] A glitch with the navigation system caused the helicopter to land 5 meters away from its intended landing site.[17]
Perseverance rover - map of the first science campaign (yellow lines, below the landing site). The blue lines above the landing site correspond to the planned second campaign,[18] although the second campaign did not officially start until the arrival of the rover at Three Forks.
The Cratered Floor Campaign was the first science campaign.[19] It began on June 1, 2021, with the goal of exploring the Crater Floor Fractured Rough and Séítah geologic units. To avoid the sand dunes of the Séítah unit, Perseverance will mostly travel within the Crater Floor Fractured Rough geologic unit or along the boundary between the two units. The first of Perseverance's sample tubes are planned to be filled during this expedition.[18]
After collecting the samples, Perseverance will return to its landing site, before continuing to the delta for its second science campaign. At some point, it will store the filled sample tubes in a designated area for the upcoming NASA-ESA Mars Sample Return mission.[20] While Perseverance embarked on its first science campaign, Ingenuity continued to travel alongside the rover as part of its operations demonstration campaign.[14]
June 1, 2021: Perseverance begins its first science campaign.[18]
June 21, 2021: Eighth flight of Ingenuity. The "watchdog issue", a recurring issue which occasionally prevented Ingenuity from taking flight, is fixed.[22]
July 5, 2021: Ninth flight of Ingenuity. This flight is the first to explore areas only an aerial vehicle can, by taking a shortcut over the Séítah unit. The sandy ripples of the Séítah unit would prove too difficult for Perseverance to travel through directly.[23][24][25]
July 7, 2021: To test its sampling system, the rover ran one sample tube through inspection, sealing and storing and the attempt was successful. Up to this point, the rover has now used 1 of its 43 sample tubes.[26]
5-August 6, 2021: Perseverance attempted to acquire its first sample from the ancient lakebed by drilling out "finger-size cores of Martian rock for return to Earth."[29][30][31] This attempt did not succeed, as the rock sampled was not sufficiently consolidated to produce an intact core and has turned to dust.[32] Up to this point, the rover has now used 2 of its 43 sample tubes.[33] Later on, the mission team confirmed that though soil samples were not cached, but in this process the rover cached the gas samples of the martian atmosphere in it, being the first gas samples cached by the rover.[34]
September 1, 2021: A second sampling attempt on a rock, named "Rochette", was successful.[36][37]
September 4, 2021: Thirteenth flight of Ingenuity.[38]
September 8, 2021: A third sampling attempt, also on Rochette, was successful.[39]

November 24, 2021: Another sample was taken from the Brac Outcrop.
December 5, 2021: Seventeenth flight of Ingenuity. Full data from the flight was not received until later, as Ingenuity initially landed in an area which prevented communication with the rover.[44]
December 15, 2021: Eighteenth flight of Ingenuity.
December 18, 2021: A sample was taken from Issole in the South Séítah Unit.
December 29, 2021: Perseverance attempted to take another sample from Issole, but was unable to successfully cache it.
January 31, 2022: The failed sample attempt from Issole was abandoned, and a new, successful sample attempt was made on Issole.
February 8, 2022: Nineteenth flight of Ingenuity. It had been planned for earlier, but a dust storm in the area caused delays.
February 25, 2022: Twentieth flight of Ingenuity.
March 7, 2022: A sample was taken from Sid in the Séítah Unit.

Upper fan campaign (January 2023 - September 2023)[edit]
The possible route for second science campaign
The Upper Fan Campaign, also called the Delta Top Campaign, is the third science campaign of the Mars 2020 mission. Whereas prior campaigns investigated areas that are believed to have been submerged in an ancient lake, this campaign will investigate one of the riverbeds that used to feed into the lake.[58][59]
March 30, 2023:Perseverance collects the first sample of the Upper Fan Campaign.[60]
April 13, 2023:Ingenuity completes its 50th flight.[61]

September 6, 2023: MOXIE completes its 16th, and final, oxygen generation test.[63]
September 15, 2023:Perseverance reaches the margin carbonate unit.[64] The third and final sample of the Upper Fan Campaign is taken.[53][65]
The Margin Campaign is the fourth, currently ongoing science campaign of the Mars 2020 mission. The campaign expected to last around 8 months, after which point Perseverance is expected to begin the Inner Rim Campaign.[66] The campaign gets its name from the geological unit it aims to explore - the margin carbonate unit. Rocks in this unit are capable of containing traces of life, and their formation is tied to the presence of liquid water.[67]
September 15, 2023: The Margin Campaign begins.[66]
September 16, 2023:Perseverance creates the "Amherst Point" abrasion batch at the Mandu Wall, beginning its first series of studies in the Margin Campaign.[66]Ingenuity sets a new height record of 20 meters, on its 59th flight.[68]
September 25, 2023:Perseverance makes its first sample of the Margin Campaign, at Pelican Point.[53]Ingenuity made its 60th flight, achieving a speed record of 8 meters per second.[69]
October 5, 2023:Ingenuity sets a new height record of 24 meters on its 61st flight.[68]
October 12, 2023: Ingenuity sets a new speed record of 10 meters per second on its 62nd flight.[68]
October 21, 2023: Perseverance collects the second sample of the Margin Campaign, and its 23rd overall.[53]
November 1, 2023:Perseverance arrives at the intersection of three geological units; the upper fan unit, margin unit, and curvilinear unit.[70]
November 8, 2023: Mars experiences solar conjunction, interfering with the ability to communicate with Perseverance and Ingenuity.[70]
December 2, 2023: Ingenuity completed 2 hours of flight in Martian atmosphere after its 67th flight.
December 12, 2023: Both of Mars 2020 spacecraft completed 1,000 solsonMars since their landing day.
January 25, 2024: NASA announces the end of the Ingenuity mission. After flight 72, examination of images of shadows of the rotor blades taken by Ingenuity's navigation and horizon cameras showed that one or more of the blades, possibly all four, were damaged during the landing, which followed a temporary communications blackout with Perseverance.[71] NASA said the damage would prevent Ingenuity from flying again and retired the craft. The helicopter flew 72 times in a period spanning almost three years; final system tests and data gathering are expected to continue for several months.[2] Ingenuity Team have named the final landing spot and resting place of Ingenuity in Airfield Chi (χ) as "Valinor Hills Station", after the fictional location in J.R.R. Tolkien’s fantasy novels.[72]
March 5, 2024: NASA released images of transits of the moon Deimos, the moon Phobos and the planet Mercury as viewed by the Perseverance rover on the planet Mars.

Samples cached for the Mars sample-return mission[edit]
In the frame of the NASA-ESA Mars Sample Return around 0.5 kilograms (1.1 lb) of soil samples along with some Martian gas samples from the atmosphere will be cached. Currently, samples are being cached by Mars 2020Perseverance Rover on the surface of Mars. Out of 43 sample tubes, igneous rock sample tubes cached-8, sedimentary rock sample tubes cached-12,[74]silica-cementedcarbonate rock sample tubes cached-1, gas sample tubes cached-1,[34] regolith sample tubes cached: 2, witness tubes cached-3,[26] tubes due to be cached-16. Before launch, 5 of the 43 tubes were designated "witness tubes" and filled with materials that would capture particulates in the ambient environment of Mars.[75]
