InSight "hears" the first quake on Mars



The InSight Seismometer recorded a "Marsquake" for the first time on April 6, 2019.

A photograph of a conserved river channel on Mars taken by a orbiting satellite whose color is superimposed to show different elevations. Blue is low and yellow is high.

NASA has been exploring Mars since 1

965. Here are some of the best moments that have captured Mars missions over the years.
The European Space Agency's Mars Express mission has taken this picture of the Korolev crater, which is more than 80 km away and filled with water ice near the North Pole.

This is the first selfie of NASA InSight on Mars. It shows the solar panels and the deck of the lander. On the deck are science instruments, weather sensor boom and UHF antenna.

This view of the Mars-Valles Marineris Hemisphere on July 9, 2013 is actually a mosaic of 102 Viking Orbiter images. At the center is the Valles Marineris canyon system, which is over 2,000 kilometers long and up to 8 kilometers deep.

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

Mars is far from a flat, barren landscape. Nili Patera is a region on Mars where dunes and waves move fast. HiRISE, aboard the Mars Reconnaissance Orbiter, continues to monitor this area every few months to determine changes in seasonal and annual timescales.

What are blueberries doing on Mars? These small, mineral-rich hematite-rich concretions are near Fram Crater, which was visited in April 2004 by NASA's Opportunity Rover. The imaged area is 1.2 inches. The view is from the microscopic imager of the Opportunity Robotic Arm, with the color information added to the Rover's Panoramic Camera. These minerals indicate that Mars had a watery past.

It is known that Mars has dust storms around the planet. These 2001 images of the NASA orbit, Mars Global Surveyor, show a dramatic change in the planet's appearance as the haze increased to the south across the globe.

Curiosity photographed the hematite Mount Sharp on September 9, 2015, a ridge full of clay minerals to create a compounded and rounded buttes with high sulfate mineral content. The shifting mineralogy in these layers of Mount Sharp suggests a changing environment in early Mars, even though they were exposed to water billions of years ago.

HiRISE has captured layered deposits and a light ice cap at the Martian North Pole.

This image, which combines data from two instruments aboard NASA's Mars Global Surveyor, shows an orbital view of the North Pole region of Mars. The ice-rich polar cap has a diameter of 621 miles and the dark bands are deep valleys. To the right of the center bisects a large ravine, Chasma Boreale, almost the ice cap. Chasma Boreale is about as long as the famous Grand Canyon of the United States and up to 1.2 miles deep.

Although Mars is not geologically active like Earth, its surface features are strongly influenced by the wind. Wind-carved features like these, called Yardangs, are common on the Red Planet. On the sand forms the wind and small dunes. In Mars's lean atmosphere, the light is not scattered very much so the shadows of the yardage are sharp and dark.

Opportunity captured the image of a Martyred Devil high on a ridge. The view looks back on the Rover's tracks that run along the northern slope of Knudsen Ridge, which is part of the southern edge of the Marathon Valley.

HiRISE has taken this picture of a kilometer-sized crater in the southern hemisphere of Mars June 2014. The crater shows in late winter on all southern slopes, as Mars goes into spring.

The Mars Reconnaissance Orbiter used his HiRISE camera to obtain this view of an area of ​​unusual texture on the south side of the lake Gale Crater.

A dramatic, fresh impact crater dominates this image taken by the HiRISE camera on November 19, 2013. The crater extends over a distance of 100 feet and is surrounded by a large blasted explosion zone. Since the area where the crater was formed is dusty, the fresh crater appears blue in the improved color of the image due to the removal of the reddish dust in that area. Opportunity used its panoramic camera to take this view east in October 31, 2010. Part of the eastern edge of the Endeavor crater, almost 30 kilometers away, is visible above the Meridiani Planum.
