Cheyava Falls is a rock discovered on Mars by NASA's Perseverance rover during its exploration of the Jezero Crater. This rock, named after a Grand Canyon waterfall, has drawn significant attention due to its potential as an indicator of ancient life on Mars. The rover's instruments detected organic compounds within the rock, which are essential for all known life. [1] [2] According to NASA, Cheyava Falls "possesses qualities that fit the definition of a possible indicator of ancient life". [3] [1]
"Cheyava Falls" is characterized by large white calcium sulfate veins and bands of reddish material, indicative of hematite, a mineral that gives Mars its rusty color. The veins are "filled with millimeter-size crystals of olivine". [1] The rock features millimeter-sized off-white splotches surrounded by black material, resembling "leopard spots." These spots contain iron and phosphate, elements often associated with microbial life. [1] [3] According to seven-step scale called Confidence of Life Detection (CoLD) used by NASA astrobiologists, the rock is on Step One, "Detect possible signal". [1]
The rock's composition suggests it was once exposed to water. However, there are alternative, non-biological explanations for its features. The rover has analyzed the rock using various instruments but concludes that a definitive understanding will require returning the sample to Earth for more in-depth study. [3]
The "arrowhead-shaped rock" was found at the northern edge of Neretva Vallis area, [4] on July 18, 2024, [5] and is 1 meter by 0.6 meters. [1] On July 21, Perseverance took a sample of the rock that became its 22nd core sample that can be delivered to Earth by future mission. [1] The rover made a "selfie" with a rock on July 23. [6]

A Mars sample-return (MSR) mission is a proposed mission to collect rock and dust samples on Mars and return them to Earth. Such a mission would allow more extensive analysis than that allowed by onboard sensors.
The two moons of Mars, Phobos and Deimos, are much smaller than Earth's Moon, greatly reducing the frequency of solar eclipses on that planet. Neither moon's apparent diameter is large enough to cover the disk of the Sun, and therefore they are annular solar eclipses and can also be considered transits.
Jezero is a crater on Mars in the Syrtis Major quadrangle, about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff.
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 25 August 2024, Perseverance has been on Mars for 1250 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.
Europa Clipper is a space probe in development by NASA. Planned for launch on the 10th October 2024, the spacecraft is being developed to study the Galilean moon Europa through a series of flybys while in orbit around Jupiter. It is the largest spacecraft NASA has ever developed for a planetary mission.
Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is an ultraviolet Raman spectrometer that uses fine-scale imaging and an ultraviolet (UV) laser to determine fine-scale mineralogy, and detect organic compounds designed for the Perseverance rover as part of the Mars 2020 mission. It was constructed at the Jet Propulsion Laboratory with major subsystems being delivered from Malin Space Science Systems and Los Alamos National Laboratory.
Lunar Flashlight was a low-cost CubeSat lunar orbiter mission to explore, locate, and estimate size and composition of water ice deposits on the Moon for future exploitation by robots or humans.

Ingenuity, nicknamed Ginny, is an autonomous NASA helicopter that operated on Mars from 2021 to 2024 as part of the Mars 2020 mission. Ingenuity made its first flight on April 19, 2021, demonstrating that flight is possible in the extremely thin atmosphere of Mars, and becoming the first aircraft to conduct a powered and controlled extra-terrestrial flight. It was designed by NASA's Jet Propulsion Laboratory (JPL) in collaboration with AeroVironment, NASA's Ames Research Center and Langley Research Center with some components supplied by Lockheed Martin Space, Qualcomm, and SolAero.

Sky crane is a soft landing system used in the last part of the entry, descent and landing (EDL) sequence developed by NASA Jet Propulsion Laboratory for its two largest Mars rovers, Curiosity and Perseverance. While previous rovers used airbags for landing, both Curiosity and Perseverance were too heavy to be landed this way. Instead, a landing system that combines parachutes and sky crane was developed. Sky crane is a platform with eight engines that lowers the rover on three nylon tethers until the soft landing.
