IN-SITU INSTRUMENT FOR MARS AND EARTH DATING APPLICATIONS
Veronica Mars is the fictional protagonist , occasional narrator through voice-overs , and antiheroine of the American television series Veronica Mars , which aired on UPN from to and on The CW from to The character was portrayed by Kristen Bell through the duration of the series. Following the show’s cancellation, Bell reprised the role in the film continuation. The character, created by Rob Thomas , was originally male and the protagonist of his unproduced novel Untitled Rob Thomas Teen Detective Novel , which eventually became the basis of the series. After the work’s transition from novel to television series, Thomas changed the character’s gender from male to female because he believed a noir piece told from a female point of view would be more interesting. Before the show starts, Veronica’s best friend, Lilly Kane, has been murdered, and her father, Keith Mars, has lost not only his position of sheriff in the fictional town of Neptune, California, but also his reputation, status, and wife. The series begins with Veronica at the bottom of her posh high school’s pecking order, having lost her popular status and popular friends because her father accused her boyfriend’s father of involvement in the murder. At the beginning of the series, Veronica is a year-old junior at Neptune High in her the fictional town of Neptune, California , which is someplace near San Diego. According to series creator Rob Thomas , Veronica’s birthday is in August.

Southwest Research Institute scientists have increased the speed and accuracy of a laboratory-scale instrument for determining the age of planetary specimens onsite. CODEX will be a little larger than a microwave and include seven lasers and a mass spectrometer. In situ measurements will address fundamental questions of solar system history, such as when Mars was potentially habitable. Then the other CODEX lasers selectively pick out and quantify the abundance of trace amounts of radioactive rubidium Rb and strontium Sr.
An isotope of Rb decays into Sr over known amounts of time, so by measuring both Rb and Sr, we can determine how much time has passed since the rock formed. While radioactivity is a standard technique for dating samples on Earth, few other places in the solar system have been dated this way. Instead, scientists have largely constrained the chronology of the inner solar system by counting impact craters on planetary surfaces.
It’s undoubtedly true.
First Rock Dating Experiment Performed on Mars
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments—like analyzing meteorites and moon rocks—have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock—with experiments performed on Mars. The work, led by geochemist Ken Farley of the California Institute of Technology Caltech , could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet.
However, shortly before the rover left Earth in , NASA’s participating scientist program asked researchers from all over the world to submit new ideas for experiments that could be performed with the MSL’s already-designed instruments. Farley, W. Keck Foundation Professor of Geochemistry and one of the 29 selected participating scientists, submitted a proposal that outlined a set of techniques similar to those already used for dating rocks on Earth, to determine the age of rocks on Mars.
Findings from the first such experiment on the Red Planet—published by Farley and coworkers this week in a collection of Curiosity papers in the journal Science Express —provide the first age determinations performed on another planet. The paper is one of six appearing in the journal that reports results from the analysis of data and observations obtained during Curiosity’s exploration at Yellowknife Bay—an expanse of bare bedrock in Gale Crater about meters from the rover’s landing site.
The smooth floor of Yellowknife Bay is made up of a fine-grained sedimentary rock, or mudstone, that researchers think was deposited on the bed of an ancient Martian lake. In March, Curiosity drilled holes into the mudstone and collected powdered rock samples from two locations about three meters apart. Once the rock samples were drilled, Curiosity’s robotic arm delivered the rock powder to the Sample Analysis on Mars SAM instrument, where it was used for a variety of chemical analyses, including the geochronology—or rock dating—techniques.
One technique, potassium-argon dating, determines the age of a rock sample by measuring how much argon gas it contains.

We review the in situ geochronology experiments conducted by the Mars Science Laboratory mission’s Curiosity rover to understand when the Gale Crater rocks formed, underwent alteration, and became exposed to cosmogenic radiation. The sedimentary rocks underwent fluid-moderated alteration 2 Gyr later, which may mark the closure of aqueous activity at Gale Crater.
Over the past several million years, wind-driven processes have dominated, denuding the surfaces by scarp retreat. The Curiosity measurements validate radiometric dating techniques on Mars and guide the way for future instrumentation to make more precise measurements that will further our understanding of the geological and astrobiological history of the planet.

Our data show that the nakhlite-source volcano grew at a rate of ca. On Earth, the majority of volcanism and planetary heat loss occurs by plate tectonics, a process driven by mantle convection 1 , with most volcanoes being active along divergent and convergent plate boundaries. A small proportion of terrestrial volcanoes are fed by mantle plumes—highly localized upwellings of abnormally hot rock that ascend from deep within the mantle and undergo partial melting at relatively shallow depths 2.
Mars, on the other hand, has lacked plate tectonics for most of its history 3 , 4. Even in cases of the slowest-moving plates, individual plume-derived volcanoes on Earth are only active for a few million years 6. Conversely, Martian plume-fed edifices have remained connected to their magma sources for extraordinary lengths of time—in some cases for billions of years 5 , 7 , 8. As a consequence, although morphologically similar to shield volcanoes on Earth, Martian volcanoes have grown to be the largest in the solar system 9 Fig.

As the ongoing robotic exploration to Mars has made some tantalising discoveries, the next major step should be retrieving samples from the Martian surface, so they can be investigated in detail in terrestrial laboratories. However, considering the huge costs associated to suh missions, an in-situ dating of rock samples is a more cost-effective approach.
Accurate estimation of absolute ages is required in order to understand Mars surface and atmosphere evolutionary processes. Thanks to the development of its innovative technology, and in addition to planetary exploration application, it will also address Earth’s field applications as a light and portable dating instrument in geology and archaeology as well as a risk assessment tool for accident and emergency dosimetry and nuclear mass-casualty events.

The search for life on the Red Planet presses on as NASA’s Perseverance rover prepares to lift off this Thursday July 30 to study the planet and search for signs of ancient life. But this isn’t the first investigation into the habitability of ancient Mars, as previous orbiters, landers and rovers have taken significant strides in the search for life. So, what do we know about possible life on Mars?
Let’s explore what previous missions and studies have uncovered about Mars and the creatures that may have once lived there. There are records of people studying Mars dating all the way back to the second century BCE, when ancient Egyptian astronomers were observing planets, stars and constellations in the night sky. Later on, through the centuries, more and more detailed descriptions of the Red Planet began popping up, leading up to the first telescopic observation of the planet in by the Italian astronomer Galileo Galilei.
With more advanced telescopic and orbital observations of the planets many years later, scientists learned that, up until about 3. While the planet’s atmosphere was stripped away scientists think that powerful solar storms could have been a major factor in the loss of atmosphere , researchers still think that it’s very possible that microscopic life could have existed in the time that Mars was more “Earth-like.
However, they think that if life existed on Mars, it was most likely microscopic — not the green and gray aliens from science fiction. Researchers believe that if life evolved on Mars similarly to how it did on Earth, it could have happened more than 3. Related: Ancient Mars lake could have supported life photos.
The missions ended up discovering unexpected chemical activity in the Mars soil but did not reveal any direct signs of past or present life of any kind. Subsequent landers and rovers continued to probe Mars’ surface and uncover clues about the planet’s history. For example, NASA’s Spirit rover , which launched in , found rocks unusually rich in magnesium and iron carbonates that had formed when the planet had a thick atmosphere and was still warm and wet.
