The cooled lava has preserved a footprint of the dunes crossed by a region of south-east of Mars. But it also looks like the "Star Trek" symbol.
The NASA InSight lander used a camera on his robotic arm to capture this sunset on Mars on April 25th.
InSight's seismometer recorded a "marsquake" for the first time on April 6, 2019.

NASA has been exploring Mars since 1965. Here are some of the best moments captured by Mars missions over the years.
The Mars Express mission of the European Space Agency (ESA) captured this image of the Korolev crater, covering more than 50 miles and filled with water ice, near the North Pole.
This is the first selfie of NASA InSight on Mars. It displays the solar panels and the landing gear deck. Its scientific instruments, temperature sensors and UHF antenna are located above the bridge.
This perspective of the Valles Marineris hemisphere of Mars, July 9, 2013, is actually a mosaic of 102 images of Viking Orbiter. In the center is the Valles Marineris canyon system, more than 2,000 kilometers long and up to 8 kilometers deep.
Rovers can also take selfies. This self-portrait of the Mars Curiosity robot shows the vehicle at the Quela drill site in the Murray Buttes area, in the lower portion of Mount Sharp.
Mars is far from a flat and barren landscape. Nili Patera is a region of Mars where dunes and ripples move quickly. HiRISE, aboard the Mars reconnaissance orbiter, continues to monitor this area every two months to observe changes in seasonal and annual time scales.
What do blueberries do on Mars? These small hematite-rich concretions are found near Fram Crater, visited by NASA's Rowing Opportunity in April 2004. The indicated area measures 1.2 inches wide. The view comes from the microscopic imager of the robotic arm of Opportunity, with color information added by the rover's panoramic camera. These minerals suggest that Mars had an aqueous past.
Mars is known to have dust storms surrounding the planet. These 2001 NASA Mars Global Surveyor orbiter images show a dramatic change in the appearance of the planet when the haze raised by the activity of the dust storm in the south became worldwide. distributed.
Curiosity took images on September 9, 2015 from Mount Sharp, a ridge rich in hematite, a plain full of clay minerals to create round, composite sulphate-rich mounds. The evolution of mineralogy in these layers of Mount Sharp suggests a changing environment in early March, although all involve exposure to water billions of years ago.
HiRISE has captured layered deposits and a bright ice cap at the North Martian Pole.
This image, which combines data from two instruments aboard NASA's Mars Global Surveyor, represents an orbital view of the northern polar region of Mars. The ice-rich polar ice cap is 621 miles wide and the dark bands are deep troughs. To the right of the center, a large canyon, Chasma Boreale, almost divides the ice cap in two. Chasma Boreale extends on the length of the famous Grand Canyon of the United States and up to 2 km deep.
Although Mars is not geologically active like the Earth, the surface features have been strongly shaped by the wind. Wind-sculpted features, called yardangs, are common on the red planet. On the sand, the wind forms undulations and small dunes. In the thin atmosphere of Mars, the light is little scattered, the shadows projected by the yardangs are clear and dark.
From its summit perched on a ridge, Opportunity recorded this image of a Martian dust demon writhing in the valley. The view returns to the rover trails leading to the northern slope of Knudsen Ridge, which is part of the southern boundary of Marathon Valley.
HiRISE took this image of a crater the size of one kilometer in the southern hemisphere of Mars in June 2014. The crater shows frost on all its southern slopes at the end of the year. Winter as Mars moves towards spring.
The Mars Reconnaissance Orbiter used its HiRISE camera to get this view of an area of unusual texture on the south floor of Gale Crater.
A spectacular and cool impact crater dominates this image taken by the HiRISE camera on November 19, 2013. The crater extends over a hundred meters and is surrounded by a large area of ray blast. Since the ground on which the crater is formed is dusty, the fresh crater appears blue in the enhanced color of the image, due to the elimination of reddish dust in this area.
Opportunity used its panoramic camera to record this view on the horizon is October 31, 2010. Part of the eastern edge of the Endeavor crater, more than 30 km away, is visible on the Meridiani map.
