PLANET MARS

CRISM observations of this region shows extensive iron/magnesium deposits which may be hydrothermal in origin. The presence of the mineral prehnite in surface and subsurface clay-forming environments on Mars could have supported habitats for microbes. This area is located in the northwest Hellas region (Southern Hemisphere). This is a non-narrated clip, using the color-enhanced center swath of the full observation. Image is less than 1 km (.67 mi) top to bottom and is 256 km (159 mi) above the surface. For full images including scale bars, visit the source link.

In this week's questions show, I tackle some challenging questions, like the ethics of sending humans to Mars, and whether it's better to focus on our efforts on Earth or on space exploration. Should we welcome a Carrington Event? Are there any serious competitors to SpaceX in the market right now? 00:00 Start 00:49 Is it ethical to send people to Mars? 04:01 Welcoming a Carrington Event? 07:07 Is Starship legitimate? 12:09 Should we spend money on space or Earth? 16:36 Is there a limit to gravitational assists? 19:46 Is there a use for small space telescopes? 22:04 Could something stand completely still? 23:24 Are there any serious contenders to SpaceX? 25:49 Will Mars have more asteroid strikes? 27:14 Will the Lunar Gateway be important? 30:58 Is it frustrating for mission name changes? 32:22 Could we ever accelerate at 1g? 33:33 Why do stars weigh so much? 35:11 Is something past the Great Attractor? Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here. 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS: https://universetoday.com/audio iTunes: https://universetoday.com/itunes Spotify: https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

NASA's Curiosity rover recently visited a rock outcrop called Mont 'Mercou' in Gale Crater on Mars. 71 images were stitched together to create a selfie.

Watch Don Banfield from Cornell discuss driving science questions for Mars at the Keck Institute for Space Studies short course "Revolutionizing Access to the Martian Surface" (March 25, 2021). What are the current high priority Mars science goals? Which can only be answered through in situ science? What measurements are needed to address these goals? https://www.kiss.caltech.edu/short_courses/access2mars.html

Presented by Michael Thorpe, NASA Johnson Space Center. Preserved in the sedimentary rock record of Mars is an ancient (more than 3 Ga) history of rivers and lakes, depicting a rich water-lain past that persisted long enough to sculpt landforms and create thick stacks of fluviolacustrine rocks. This rock record illuminates a time when ancient rivers and streams on the surface of Mars physically and chemically altered the terrains and then transported and deposited sediments in downstream basins (i.e., source-to-sink). Since landing in Gale crater, the Mars Science Laboratory Curiosity rover has traversed over approx. 400 m of one of these sedimentary basins, exploring mudstones, sandstones, and even conglomerates from the Bradbury and Mount Sharp groups. To help paint the picture of what the paleoenvironment of Mars looked like, we shift our focus to similar environments on Earth, searching for clues to piece together a complex sedimentary story.

This image was requested to take a closer look at streamlined features in Argyre Planitia and their relationship to the surrounding topography. In particular, we want to determine the nature of their origin: could these be yardangs, or possibly drumlins? Topographic data is necessary to understand the formation of these features, especially symmetry and asymmetry. This scene is located in Hooke Crater, which is 139 kilometers in diameter and was named after British physicist-astronomer Robert Hooke. This is a non-narrated clip. Image is less than 5 km across and is 256 km above the surface. For images including scale bars, visit the source link.

This image is one of the many that HiRISE acquired to the assist the Perseverance team in selecting a potential landing site that would be safe for the rover but also accomplish the team’s science goals. This is *not* where Perseverance eventually touched down. This picture is of the western rim of Jezero, far away from the rover itself, which is furthest east in the interior. An image like this one can also help characterize possible hazards for robotic explorers. As the most powerful camera ever sent to another planet, HiRISE plays a crucial role for future missions to the Red Planet. Audio track features loops of two recordings by Perseverance: the wind and the sound of it driving on the surface. For more, see: https://soundcloud.app.goo.gl/j2d16fmLDj9UVfWe9 This is a non-narrated clip. Image is less than 5 km across and is 282 km (175 mi) km above the surface. https://www.uahirise.org/ESP_062319_1985 NASA/JPL/UArizona #Mars #science

WHY MARS? In this video I went down a more unconventional path where rather than talking about the details of the missions I went into the WHY does it even matter!?! A philosophical perspective of the missions/theories rather than just stating the missions/theories. You can easily learn all the possible details of these missions at NASA’s YouTube channel, but this I wanted to delve into the importance that these missions serve. 0:34 - list of missions 1:00 - MOXIE 1:44 - RANT BEGINS 5:33 - Who this impacts As always thanks for watching!

Meet Mars 2020, NASA's Next Rover Nov. 16 at 7 p.m. PT (10 p.m. ET, 0300 UTC) Soon, NASA and JPL will once again rove the Red Planet with Mars 2020. Its mission objectives include exploration of extremely ancient Martian habitats and the collection of a set of samples that could one day be returned to Earth. Analysis of carefully selected samples from Mars in laboratories on Earth would transform planetary science and the search for extraterrestrial life. Join us as we discuss the evolving scientific strategy for Mars 2020, including the selection of a landing site. Speaker: Ken Williford, the deputy project scientist for Mars 2020 and director of the the JPL Astrobiogeochemistry Laboratory (abcLab)

These geologically youthful faults in Aureum Chaos have been imaged by HiRISE before, so our purpose is to use this observation to complete a stereo pair and create a digital terrain model. We can then measure the fault offsets, if any. Aureum Chaos is a canyon system with collapsed areas, often called “chaotic terrain.” The Mars Express orbiter has identified clay minerals in a variety of places within Aureum Chaos. “Aureum” is the Latin word for “gold.” This is a non-narrated clip. Image is less than 5 km (3 mi) across and is 271 km (168 mi) above the surface. For images with scale bars, visit the source link.

This HiRISE image shows faulted layered deposits in a part of Valles Marineris called Candor Chasma. Often, faults cut through the layered material in this area, indicating that the rocks underwent stress causing them to crack and shift in position after they were deposited. This area also has a high abundance of hematite. Hematite is a mineral that can precipitate out of water, so its presence on Mars is of special interest for understanding the distant past. This is a non-narrated clip. Image is less than 5 km across and is 265 km above the surface. For full image information, including scale bars, visit the source link.

Look up to the night sky just before dawn, or after dusk, and you might see a faint column of light extending up from the horizon. That luminous glow is the zodiacal light, or sunlight reflected toward Earth by a cloud of tiny dust particles orbiting the Sun. Astronomers have long thought that the dust is brought into the inner solar system by a few of the asteroid and comet families that venture in from afar. But now, a team of Juno scientists argues that the planet Mars may be the culprit. An instrument aboard the Juno spacecraft serendipitously detected dust particles slamming into the spacecraft during its journey from Earth to Jupiter. The impacts provided important clues to the origin and orbital evolution of the dust, resolving some mysterious variations of the zodiacal light.
