Mission & # 39; Mars got lucky: NASA artery earned a krater filled with sand, which facilitates the study & # 39; inside Earth Science


Images from space Insight show that fits inside a flat skull and filled with sand.

PASADENA, CALIFORNIA-F & # 39; World laboratory, the marsforming had already started.

27 & # 39; in November, the day of & # 39; after landing b & # 39; Länder Insight success & # 39; NASA f & # 39; Mars, after the television crews left, the technicians here at the Jet Propulsion (JPL Laboratory ) were already working, simulation & # 39; Mars to model & # 39; , They call Foresight. Scientists still do not know exactly in which Mars Insight. But the first few images sent back to Earth set his immediate environment and the Lander is somewhat diffuse, b & # 39; 4 °. So yesterday, NASA engineers were playing in the sand, moving to fake Mars rock into position. Strengthened Foresight on their shoulders while shoving small blocks under the wing of arter to get it just right listing.

Look over gallery & # 39; over Foresight was Matt Golombek, the ġologu JPL will lead placement & # 39; two instruments & # 39; Insight, heat probe and sismometru. From the few photos returned the & # 39; now, he says, teaches much about his place, which closely resembles the marzjani land previously the owner of spirit.

For example, Insight landed in & # 39; what is called blank, krater was filled with soil and turned flat. In pictures taken by the robotic arm elbow stored in landing, the end of the krater is visible. Once the team determines the diameter of the krater, can & # 39; there are meters, perhaps tens of & # 39; Researchers can infer meters depth and the amount of & # 39; sand surrounded it. Either way, whether it happens to the heat probe instrument, called HP3, to penetrate the material in & # 39; facility. "This is a good news for HP3 how you & # 39; possibly hope", he says.

Landing in empty was lucky for another reason. Insight does not adversely affect the area of ​​the Eye of & # 39; landing of its target, and ended in the terrain, b & # 39; in general, it is more rock than desired. But the gap is mostly absent from the rock. One, about 20 centimeters across, sit near the feet & # 39; artery, while three are smaller & # 39; apart, but nothing threatening placement & # 39; instruments. The blank is flat and m & # 39; has sand dunes, and small pebbles to indicate surface dense enough to support the weight of the instruments. "I will not have any problem," said Golombek.

The biggest mystery for the Lander team now is to find out exactly where he is. The orbitatur of & # 39; Mars push the center of the image area & # 39; landing Thursday will miss the landing, because it has lost a little center. Insight on instrument called the inertial measurement unit prepared the place for circle & # 39; 5 kilometers. Entry, descent and landing team Insight to refine that estimate up to one kilometer or less. "But have not done so happy to have landed with & # 39; safe way to know what made the night on the night," Golombek said with a smile. "And yet not been demonstrated today."

There are other techniques that can & # 39; help: The third primary experiment & # 39; Insight, called the Experiment & # 39; of & # 39 structure; Rotation and Interior (RISE). The main objective of both sensitive antennas & # 39; hearing of RISE is to find wobbles in the Martian core. But the Insight team can & # 39; also use them to mark the latitude and longitude of & # 39; waste by using radio signals & # 39; the orbitaturi to pass. This gave geologists in place & # 39; about 100 meters or so.

Now, good competition is turned on. Golombek and his peers hope to overcome satellites to fix the place & # 39; Insight. They have 6 & # 39; December, when orbitatur x & # 39; probably acquire. Right now, they are widening the weak image, try to match their gap with & # 39; & # 39 existing maps; high resolution. Their work will be easier next week, when the camera on the elbow of the robotic arm is extended to record the floor arterjana in detail. For now, the arm is stowed – Tuesday was about simple steps, such as escape from small fees to ensure the arm on deck. But later this week, after the camera limits are turned off and the arm is released, the detailed investigation starts.
