The water on Mars probably doesn't have much oxygen, but new models show that life doesn't need as much O2 as we thought. And NASA is sending a claw machine to the red planet!

It’s well-established that the Martian surface is completely inhospitable to life as we know it, but recent research suggests that may not be the case down below.

In this episode of the Case for Mars, we look at the recently discovered lake on Mars, and how it was discovered. We discuss the MARSIS experiment, that is able to use Ground Penetrating Radar to detect changes in minerals, ice, or liquids underground. We also discuss what NASA thinks about this discovery, and whether or not life could exist in this lake. Thanks for watching! And consider subscribing if you enjoyed this video!

A study published July 23 in the journal Astrobiology said there was a time when the moon had the right conditions to support life.

The Moon doesn’t appear to have what it takes to support life now, but researchers suggest that wasn’t always the case.

According to a report by Geek.com, a new study suggests that Saturn’s largest moon, Titan, may have the potential to produce life as we know it. A team of researchers using data from the Cassini spacecraft examined the icy moon looking for biological molecules. Leader of the study Catherine Neish, found that when exposed to liquid water, organic molecules like the ones on Titan are capable of producing a range of biomolecules, including amino acids. Neish and her team reportedly focused their attention on craters, particularly Sinlap, Selk, and Menrva. The team wrote, “We determine that the best sites to identify biological molecules are deposits of impact melt on the floors of large, fresh impact craters." https://www.geek.com/news/psst-alien-hunters-check-inside-craters-on-saturns-moon-titan-1746989/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Title: “Test of genetic code evolution hypotheses: Reverse evolution of specific target proteins by mRNA-display technique” Speaker: Valerio Guido Giaobell AbGradCon 2018 June 4th-8th Atlanta, GA AbGradCon (Astrobiology Graduate Conference) provides a unique setting for astrobiologically-inclined graduate students and early career researchers to come together to share their research, collaborate, and network. AbGradCon 2018 marks the 14th year of this conference—each time in a different place and organized by a different group of students, but always with the original charter as a guide. These meetings have been wildly successful both when connected to AbSciCon, and as stand-alone conferences. Since it is organized and attended by only graduate students, post docs, and select undergraduates, AbGradCon is an ideal venue for the next generation of career astrobiologists to form bonds, share ideas, and discuss the issues that will shape the future of the field.

Recently NASA announced that the Curiosity rover discovered organic molecules in an ancient mudstone on Mars. In this video, we discuss the importance of this discovery, how the Curiosity rover was able to determine that it was organic molecules, and what these discoveries mean for future missions to the Red Planet.

The ExoMars Rover is expected to land on the Mars in two years. The ExoMars Rover contains a miniature chemistry lab. NASA is going to use the miniature chemistry lab to search for sign of life on Mars. The Mars Organic Molecule Analyzer will analyze organic molecules like amino acids. NASA employees and space fans are extremely excited to find out if there's life on Mars. https://www.digitaltrends.com/cool-tech/exomars-rover-mars-organic-molecule-analyzer/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The Search for Life: Near & Far Presented by Dr. Shawn Domagal-Goldman Exploring Life Origins and the Universe: A Networking Event March 30th, 2018 The Georgia Tech Astrobiology Colloquium is a new early career event for the Georgia Tech astrobiology community and consisted of presentations and talks by students (both graduate and undergraduate) and post-doctoral fellows working in astrobiology, space science, and engineering across the Georgia Tech campus and greater Atlanta. There are also plenary lectures given by distinguished members of the global astrobiology community. Plenary Speakers: Dr. Ada Yonath Dr. Niles Lehman Dr. Shawn Domagal-Goldman Organizing Committee: Moran Frenkel-Pinter Kennda Lynch George Zaharescu Faculty Advisors: Martha Grover Glenn Lightsey Jennifer Glass

Night Sky Network members joined us on April 25, when Dr. Bruce Damer and Prof. David Deamer from NASA's Astrobiology Institute shared the latest research into the origins of life in the universe. In recent years, an approach to the long standing question of "how did life begin?" has returned to Charles Darwin's original intuition of "a warm little pond". Evidence from chemistry, geology and complexity science is accumulating to support a beginning for life on Earth, over four billion years ago, in fluctuating hot spring pools. Dr. Damer and Prof. Deamer will outline their new scenario and take us out into the solar system to Mars, Enceladus and beyond to exoplanets to address how this might inform our search for evidence life in the universe.

Join NASA's Jet Propulsion Laboratory scientists and engineers and get a sneak peek of the upcoming InSight Mars mission, the first to focus on examining the deep interior of Mars. Launching in May 2018, this lander will be the very first interplanetary launch from the West Coast. The Exploratorium will host the InSight Roadshow with a half-scale model of the lander and an array of instruments. InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is a NASA Discovery Program mission that will place a single lander on Mars. InSight is more than a Mars mission; it’s a terrestrial planet explorer that will address one of the most fundamental questions of planetary and solar system science: what are the processes that shaped the rocky planets of the inner solar system, including Earth, more than four billion years ago? By using sophisticated geophysical instruments, InSight will delve deep beneath the surface of Mars, detecting the fingerprints of the processes of terrestrial planet formation, as well as measuring the planet's “vital signs”: its "pulse" (seismology), "temperature" (heat flow probe), and "reflexes" (precision tracking).
