PLANET MARS

We’ve monitored the so-called Happy Face Crater in the south polar region of Mars for almost a decade. Two images that we took, one in 2011 and the other in 2020, at roughly the same season, show color variations that are due to different amounts of bright frost over darker red ground. Black and white is less than 5 km across; enhanced color is less than 1 km. For full images including scale bars, visit the below link.

This observation is located within in a massive impact crater in Noachis Terra (Land of Noah), and our primary interest are the linear ridges and windblown bedforms on the floor. The strong linearity of the ridges suggest tectonic processes, and the small-scale topography might help us understand them better. Noachis Terra is an extensive landmass in the Southern Hemisphere of Mars. This is a non-narrated clip. Image is less than 5 km across and is 256 km above the surface.

These beautiful patterns are likely caused by the contraction and expansion of underground ice. Noachis Terra is an extensive landmass in the Southern Hemisphere of Mars, to the west of the massive Hellas impact basin. This a non-narrated clip. The image is less than 5 km across and is 250 km (155 mi) above the surface. North is down. For images with scale bars, visit the below link. Music: “Two Faces” by Causmic (used by permission).

Our rationale for this image is take a current look at the terrain now to detect for future changes in the topography of this gorgeous sea of dunes. This picture is of the enhanced color center swath, located in the north polar region of Mars known as Vastitas Borealis, the wastelands of the north. This is a non-narrated clip with ambient sound added. Image is less than 1 km across. For full map-projected images including scale bars, visit the below link.

This observation gives us a large and superb exposure of phyllosilicates in northwest Hellas. Silicates form a large group of minerals that includes, among others, micas, smectites, and kaolinites. The existence of phyllosilicates (also called “sheet silica” on Mars goes back to analyses done by the Viking Lander. On Earth, silicates comprise about 90 percent of rock mineral composition. Pay attention to the bright, blueish rocky outcrops. For additional info, see: https://www.jpl.nasa.gov/news/news.php?release=2015-377 The word “silica” derives from Latin “silex”, meaning flint or hard stone. This is a non-narrated clip, using the center enhanced color swath and north is to the right. For full images including scale bars, please visit the below link.

The rationale for this observation was for seasonal dune and frost monitoring. But this veritable sea of beautiful dunes seems to be reason enough. Lomonosov is approximately 150 kilometers in diameter, and is located in the Martian northern plains. It’s possible that the impact that created the crater might have been responsible for creating tsunami waves from an ancient ocean. This is a non-narrated clip. Image is less than 5 km (or 3 mi) across. For full images including scale bars, please see the below link. Music: “Resolver” by Amulets (used by permission).

Join Scientific American for a conversation about the next steps in humanity’s reconnaissance of Mars. Featuring Casey Dreier, senior space policy adviser at The Planetary Society, and space & physics editor Lee Billings, this deep dive will begin with an overview of NASA’s upcoming Perseverance rover, slated to land on Mars in February 2021 to search for signs of past and present life and to gather samples for future return to Earth. Dreier and Billings will also discuss the “post-Perseverance” future in which space agencies and private companies may pursue major shifts in Mars exploration strategies, and how those plans could forever change our understanding of—and relationship with—the Red Planet.

Mars is a fascinating and mysterious world, with stories of what was once a much more familiar world written all over its surface. Mars was once a water world, with oceans on its surface near the beginning of the Solar System. Today, we will relive Mars' history and legacy, as we examine the red planet's past, present and future. Subscribe for more Space Exploration & Astronomy! So close to #300K subscribers now!

Breccia is a rock typically consisting of rock fragments of various sizes and shapes that have been broken, tumbled and cemented together in sudden geologic event (e.g., a landslide, a flash flood or even an impact-cratering event). The prefix “mega” implies that the breccia consists of clasts, or rock fragments, that are typically bigger than a large house or a building. This image is located within Holden Crater. Holden likely experienced extensive modification by running water, which is supported by observations of drainage and deposition into the crater from a large channel (Uzboi Valles) breaching crater’s southwest rim. This is a non-narrated clip. Image is less than 5 km (or 3 mi) across. For images including scale bars, see the below website link. Music: “Melissa,” by Eveningland (used by permission).

How much water is hiding under the Martian surface? Learn how China's Tianwen-1 mission to Mars will help us solve the mystery. #Shorts Tianwen-1 is not China’s first Mars mission. Yinghuo-1, an attempted orbiter was the first. It launched in 2011, but due to an upper stage failure it never made it past Earth orbit.

Coprates Chasma is located at the eastern end of the Valles Marineris canyon system, and always provides fantastic-looking images. This observation shows very steep slopes on the wall of the chasma, with extensive sedimentary fans. Additionally, we see thick layers of bedrock. The chasma is about 966 kilometers (600 miles) in length. Could there have been a lake here in the ancient past? This is a non-narrated clip. Black and white is less than 5 km across; enhanced color is less than 1 km. For full images including scale bars, see the below link. Music: “In the Void” by Amulets (used by permission).

Mars has changed since it formed 4.6 billion years ago. When life started on Earth ~4 billion years ago, Mars was habitable too, with volcanism, a magnetic field, surface water and a thick atmosphere. Today, Mars is cold and dry, with a thin atmosphere and harsh surface. In this lecture Professor Andrew Coates will discuss the search for life beyond Earth on our closest target, using the Rosalind Franklin rover. A lecture by Andrew Coates The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/mars Gresham College has been giving free public lectures since 1597.

A Context Camera image shows sinuous ridges and possible layers at this location, which is within an alluvial-fan-bearing crater. One possible interpretation: erosion has formed inverted channels and incised into distal-alluvial-fan or deltaic materials. HiRISE resolution needed to measure channel widths and layer orientations. The ridges remain fairly sharp-looking despite the passing of time. The blueish sand is likely basalt (volcanic origin) and there are bright exposure of bedrock throughout. This is a non-narrated clip, using the center enhanced color swath, less than 1 km across, and 257 km above the surface. For full images including scale bars, see the below link.
