Life may have existed on warm, rainy, ancient March before winter cam

A recent photo taken by the Curiosity rover shows its current location, known as "Teal Ridge." The rover has been studying the clay-bearing unit in this region.

Cooled lava helped a footprint of where dunes once moved to southeastern region on March. But it also looks like the "Star Trek" symbol.

NASA's InSight lander used a camera on its robotic arm to capture this sunset on March 25th.

InSight's seismometer recorded a "marsquake" for the first time on April 6, 2019.

NASA has been exploring March since 1965. Here are some of the best moments captured by Mars missions over the years.
The European Space Agency's Mars Express mission captured this image of the Korolev crater, more than 50 miles across and filled with water ice, near the north pole.

This is NASA InSight's first selfie on Mars. It displays the lander's solar panels and deck. On top of the deck are its science instruments, the weather sensor booms and the UHF antenna.

This perspective of Mars' Valles Marineris hemisphere from July 9, 2013, is actually a mosaic of 101 Viking Orbiter images. At the center is the Valles Marineris canyon system, over 2,000 kilometers long and up to 8 kilometers deep.

Rovers can take selfies, too. This self-portrait of the Curiosity Mars rover shows the vehicle at the Quela drilling location in the Murray Buttes area on lower Mount Sharp.

Mars is far from a flat, barren landscape. Nili Patera is a region on March in which the dunes and ripples are moving rapidly. HiRISE, onboard the Mars Recognition Orbiter, continues to monitor this area.

What are blueberries doing on Mars? These small, mineral hematite-rich concretions are near Fram Crater, visited by NASA's Opportunity rover in April 2004. The area shown is 1.2 inches across. The view comes from the microscopic imager on robotic arm, with color information added from the rover's camera. These minerals suggest that Mars had a watery past.

Mars is known to have planet-encircling dust storms. These 2001 images from NASA's Global Mars Surveyor orbiter show a dramatic change in the planet's appearance when it has become globally distributed.

Curiosity took pictures on September 9, 2015, of Mount Sharp, a hematite-rich ridge, a plain full of clay minerals to create a composite and rounded buttes high in sulfate minerals. The changing mineralogy in these layers of Mount Sharp suggests a changing environment in early March.

HiRISE captured layered deposits and a bright ice cape at the Martian north pole.

This image, combining data from two NASA's Mars Global Surveyor instruments, orbital records from the north polar region of Mars. The ice-rich polar cap is 621 miles across, and the dark bands in are deep troughs. To the right of center, a large canyon, Chasma Boreale, almost bisects the ice cap. Chasma Boreale is about the length of the United States' famous Grand Canyon and up to 1.2 miles deep.

Although Mars is not geologically active like Earth, surface features have been heavily shaped by wind. Wind-carved features such as these, called yardangs, are common on the Red Planet. On the sand, wind ripples and small dunes. In Mars' thin atmosphere, light is not scattered much, so the shadows cast by the yardangs are sharp and dark.

From its perch high on a ridge, Opportunity recorded this image of a Martian dust devil twisting through the valley below. Knudsen Ridge, which forms part of the southern edge of Marathon Valley.

HiRISE took this picture of a March-March 2014 issue of the March in March.

The Mars Reconnaissance Orbiter used its HiRISE camera to get this view of an area with unusual texture on the southern floor of Gale Crater.

A dramatic, fresh impact crater dominates this image taken by the HiRISE camera on November 19, 2013. The crater spans approximately 100 feet and is surrounded by a large, rayed blast area. Because the field is shaped like dusty, the freshest crater appears in the color of the image, due to removal of the reddish dust in that area.

Opportunity to use this camera to record this eastward horizon view on October 31, 2010. A portion of Endeavor Crater's eastern rim, nearly 19 miles in the distance, is visible over the Meridiani Planum.
