A historic moment is on the horizon for NASA’s first asteroid sample return mission, OSIRIS-REx. On Oct. 20, the spacecraft will descend to asteroid Bennu’s surface, touch down for a few seconds and collect a sample of the asteroid’s rocks and dust, which will be returned to Earth for study. NASA astrobiologists Dr. Jason Dworkin and Dr. Scott Sandford explain the importance of the OSIRIS-REx mission in the quest to understand the role that asteroids and other small bodies play in the origins of life on Earth. #ToBennuAndBack asteroidmission.org astrobiology.nasa.gov Featuring Dr. Jason Dworkin (NASA Goddard Space Flight Center) Dr. Scott Sandford (NASA Ames Research Center) Video & images are courtesy of NASA and its affiliates. Music by Bensound.com (License certificate #1999293) Directed & Edited by Mike Toillion About OSIRIS-REx: NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft is the first U.S. mission to return samples from an asteroid to Earth, addressing multiple NASA Solar System Exploration objectives. OSIRIS-REx launched from Cape Canaveral on September 8, 2016. OSIRIS-REx completed its 1.2 billion-mile journey to arrive at the asteroid Bennu on December 3, 2018. On October 20th, 2020, it will make its first attempt to capture a sample of the asteroid's regolith. Asteroids are the leftover debris from the solar system formation process that began over four billion years ago, and they can teach us a lot about the history of the Sun and planets. Bennu may contain the molecular precursors to the origin of life and the Earth’s oceans. Bennu is also a potentially hazardous asteroid that has a relatively high probability of impacting the Earth late in the 22nd century. OSIRIS-REx will determine Bennu’s physical and chemical properties, which could be critical for developing an impact mitigation mission in the future.

A new study suggests the recipe is different but Saturn’s moon Titan has the necessary ingredients for life. Catherine Neish, a member of Western’s Institute for Earth and Space Exploration (Western Space), together with her colleagues at the European Space Agency (ESA) investigated Titan using advanced imaging technology.

Researchers from Cardiff University and MIT just published a paper in Nature in which they claim to have found phosphine, a possible biosignature, in the clouds of Venus' atmosphere. Join David Grinspoon, astrobiologist at the Planetary Science Institute who serves on the SETI Institute's Science Advisory Board, and Nathalie Cabrol, Director of the Carl Sagan Center at the SETI Institute, in a discussion about the possibility of life on Venus.

Scientists at MIT, Cardiff University, and elsewhere have observed what may be signs of life in the clouds of Earth's planetary neighbor, Venus. (Learn more: http://news.mit.edu/2020/life-venus-phosphine-0914) Watch more videos from MIT: http://www.youtube.com/user/MITNewsOffice?sub_confirmation=1 The Massachusetts Institute of Technology is an independent, coeducational, privately endowed university in Cambridge, Massachusetts. Our mission is to advance knowledge; to educate students in science, engineering, technology, humanities and social sciences; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place. The MIT YouTube channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.

The Mars 2020 Perseverance Rover successfully launched on July 30, 2020, is now en route toward Mars. The mission will pave the way for future human expeditions to Mars and demonstrates technologies that could be used by future Mars explorers.

This lecture is part of the free and open to the public lecture series for the Royal Astronomical Society's bicentenary celebrations in 2020. Have you ever wondered how life might be able to survive in the extreme conditions that we find on planets and moons beyond the Earth? Join Rosie Cane from the UK Centre for Astrobiology at The University of Edinburgh, as she introduces the subject of astrobiology and how her PhD research looking at micro-organisms in multiple-extreme environments is not only helping in the search for life on other planetary bodies, but also helping us to understand life on our own planet. From ‘What is Life’ to ‘Are We Alone in the Universe’, Rosie will address some of the biggest questions out there, covering why we think bacteria are the best bet for potential life on another planet, how they survive extreme environments too hostile for humans to handle and where in the Solar System current research shows potential for finding extant/extinct life. She will also cover science goals from exciting upcoming European Space Agency missions to advance the search for life beyond the Earth, such as ExoMars, the Jupiter Icy Moon Explorer (JuIcE) and Dragonfly mission to Saturn’s moon, Titan. If you’re interested in bacteria, extreme environments and the search for life beyond Earth then please do come along!
