The Urey instrument, or Urey: Mars Organic and Oxidant Detector was a developmental spacecraft instrument for detecting organic compounds including amino acids. [1] [2]
It was funded by NASA and tested in the Atacama Desert in the early 2000s. [2] Urey was selected by NASA for further development in support ExoMars or any future Mars mission that could use Urey along with Mars Organic Molecule Analyzer, or Moma in 2007, funded with 1.5 million USD total (750k each). [3] [4] Urey was a suite of instruments that built on 15 years of research into detecting organic molecules. [5] Urey is a design for in situ biomarker detection, and it was tested in the early 2000s. [6] The device would also study the mysterious oxidants in Mars regolith. [7]
Urey was previously included on ExoMars rover, now the Rosalind Franklin rover, in one of its iterations, and would have searched for organic compounds in Martian rocks and soils as evidence for past life and/or prebiotic chemistry. Starting with a hot water extraction, only soluble compounds are left for further analysis. Sublimation, and capillary electrophoresis makes it possible to identify amino acids. The detection would be by laser-induced fluorescence, a highly sensitive technique, capable of parts-per-trillion sensitivity. These measurements would be made at a thousand times greater sensitivity than the Viking GCMS experiment, and would significantly advance our understanding of the organic chemistry of Martian soils. [8] [9] [10] Urey would follow up on the Viking results which were inclusive and only sampled the very near surface. [11]
Urey had been selected for a time to be on the Pasteur payload of the Rosalind Franklin rover, [11] however, it was developed for any Mars mission not necessarily ExoMars and was funded independently by NASA. [4]
One of the components of Urey was the Mars Oxidant Instrument (MOI) and it was developed by NASA's Ames Research Center. [12]
Urey Suite: [13]
Urey is named after Harold Clayton Urey (1893 – 1981) for his contributions to chemistry and other studies including winning the Nobel Prize in Chemistry in 1934. [11] [14]
Cosmochemistry or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. This is done primarily through the study of the chemical composition of meteorites and other physical samples. Given that the asteroid parent bodies of meteorites were some of the first solid material to condense from the early solar nebula, cosmochemists are generally, but not exclusively, concerned with the objects contained within the Solar System.
The possibility of life on Mars is a subject of interest in astrobiology due to the planet's proximity and similarities to Earth. To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.
A biosignature is any substance – such as an element, isotope, molecule, or phenomenon – that provides scientific evidence of past or present life on a planet. Measurable attributes of life include its complex physical or chemical structures, its use of free energy, and the production of biomass and wastes.
In 1976 two identical Viking program landers each carried four types of biological experiments to the surface of Mars. The first successful Mars landers, Viking 1 and Viking 2, then carried out experiments to look for biosignatures of microbial life on Mars. The landers each used a robotic arm to pick up and place soil samples into sealed test containers on the craft.
The Astrobiology Field Laboratory (AFL) was a proposed NASA rover that would have conducted a search for life on Mars. This proposed mission, which was not funded, would have landed a rover on Mars in 2016 and explore a site for habitat. Examples of such sites are an active or extinct hydrothermal deposit, a dry lake or a specific polar site.
The Mars general circulation model is the result of a research project by NASA to understand the nature of the general circulation of the atmosphere of Mars, how that circulation is driven and how it affects the climate of Mars in the long term.
The Mars Astrobiology Explorer-Cacher (MAX-C), also known as Mars 2018 mission, was a NASA concept for a Mars rover mission, proposed to be launched in 2018 together with the European ExoMars rover. The MAX-C rover concept was cancelled in April 2011 due to budget cuts.
Interplanetary contamination refers to biological contamination of a planetary body by a space probe or spacecraft, either deliberate or unintentional.
Rosalind Franklin, previously known as the ExoMars rover, is a planned robotic Mars rover, part of the international ExoMars programme led by the European Space Agency and the Russian Roscosmos State Corporation. The mission was scheduled to launch in July 2020, but was postponed to 2022. The Russian invasion of Ukraine has caused an indefinite delay of the programme, as the member states of the ESA voted to suspend the joint mission with Russia; in July 2022, ESA terminated its cooperation on the project with Russia. As of May 2022, the launch of the rover is not expected to occur before 2028 due to the need for a new non-Russian landing platform.
Sample Analysis at Mars (SAM) is a suite of instruments on the Mars Science Laboratory Curiosity rover. The SAM instrument suite will analyze organics and gases from both atmospheric and solid samples. It was developed by the NASA Goddard Space Flight Center, the Laboratoire des Atmosphères Milieux Observations Spatiales (LATMOS) associated to the Laboratoire Inter-Universitaire des Systèmes Atmosphériques (LISA), and Honeybee Robotics, along with many additional external partners.
CheMin, short for Chemistry and Mineralogy, is an instrument located in the interior of the Curiosity rover that is exploring the surface of Gale crater on Mars. David Blake, from NASA Ames Research Center, is the Principal Investigator.
Icebreaker Life is a Mars lander mission concept proposed to NASA's Discovery Program. The mission involves a stationary lander that would be a near copy of the successful 2008 Phoenix and InSight spacecraft, but would carry an astrobiology scientific payload, including a drill to sample ice-cemented ground in the northern plains to conduct a search for biosignatures of current or past life on Mars.
Jeffrey L. Bada is an American chemist known for his works in the study of the origin of life. He is distinguished research professor of marine chemistry and former director of the NASA Specialized Center of Research and Training (NSCORT) in Exobiology at the Scripps Institution of Oceanography, University of California, San Diego. Bada has played a pioneering role in the development of the Mars Organic Detector (MOD) instrument package that is designed to search for amino acids and other organic compounds directly on the surface of Mars during future ESA and NASA missions.
The Mars Organic Molecule Analyser (MOMA) is a mass spectrometer-based instrument on board the Rosalind Franklin rover to be launched in 2028 to Mars on an astrobiology mission. It will search for organic compounds in the collected soil samples. By characterizing the molecular structures of detected organics, MOMA can provide insights into potential molecular biosignatures. MOMA will be able to detect organic molecules at concentrations as low as 10 parts-per-billion by weight (ppbw). MOMA examines solid crushed samples exclusively; it does not perform atmospheric analyses.
MicrOmega-IR is an infrared hyperspectral microscope that is part of the science payload on board the European Rosalind Franklin rover, tasked to search for biosignatures on Mars. The rover is planned to be launched not earlier than 2028. MicrOmega-IR will analyse in situ the powder material derived from crushed samples collected by the rover's core drill.
Raman Laser Spectrometer (RLS) is a miniature Raman spectrometer that is part of the science payload on board the European Space Agency'sRosalind Franklin rover, tasked to search for biosignatures and biomarkers on Mars. The rover is planned to be launched not earlier than 2028 and land on Mars in 2029.
ADRON-RM is a neutron spectrometer to search for subsurface water ice and hydrated minerals. This analyser is part of the science payload on board the European Space Agency'sRosalind Franklin rover, tasked to search for biosignatures and biomarkers on Mars. The rover is planned to be launched not earlier than 2028 and land on Mars in 2029.
WISDOM is a ground-penetrating radar that is part of the science payload on board the European Space Agency'sRosalind Franklin rover, tasked to search for biosignatures and biomarkers on Mars. The rover is planned to be launched not earlier than 2028 and land on Mars in 2029.
