Mars new home "big sandbox"

The Insight spacecraft NASA launched coverage of the lens on the camera of Instrument Context (ICC) thereof on 30 & # 39; November 2018 and took this view of & # 39; Mars. Located under the deck & # 39; the inverter Insight, the ICC has a view of ozone, and create curved horizon. Some groups & # 39; still visible dust on the camera lens.

B & # 39; Insight safely on the surface of & # 39; Mars, the mission team at the Jet Propulsion Laboratory of & # 39; NASA f & # 39; Paceadena, California, is working much more on the site of the landing area. They knew when Insight issued 26 & # 39; November that the spacecraft had lost the target, said lava plain Elysium Planitia. Now they determined the vehicle sits & # 39; slightly oblique (about 4 degrees) in a krater & # 39; low impact and & # 39; dust and sand known as "empty". Insight has been designed to work on a surface with & # 39; inclination to 15 degrees.


"The science team was hoping to land in & # 39; sandy area with few rocks because we chose the site & # 39; landing, so we can not be happy", said project manager Insight Tom Hoffman & # 39; JPL. "M & # 39; there is no landing pads or runways on Mars, so to fall in & # 39; area is basically the large sand area without large rocks to make deployment easier instruments and provides great for our mole to start digging. "

The feature of roasting grade and slope in the landing and safety is also important to determine whether Insight can succeed in its mission after landing. The rocks and slopes can affect the ability of & # 39; Insight to put its heat probe also known as "mole" or HP3– and sismometru ultra-sensitive, known as SEIS, on the surface of & # 39; Mars.

Leaving on a steep slope in & # 39; wrong direction can & # 39; also be compromised of Space ability to achieve adequate production of energy from its two solar arrays, while landing near great rock could & # 39; avoid Insight can & # 39; open one of those arrays. In fact, both fully deployed just after landing arrangements.

The preliminary assessment of Insight science team photo taken the & # 39; now about the area & # 39; landing suggests that the area in the immediate vicinity of & # 39; the arter is raised by only a few rocks. Images b & # 39; higher resolution are expected to start arriving during the next few days, after Insight releasing the clear plastic dust retained optical both safe spacecraft cameras during landing.

"We are looking for pictures & # 39; higher definition to confirm this preliminary assessment," said Bruce Banerdt of JPL, principal investigator of & # 39; Insight. "If these few images b & # 39; reducing the resolution of jkoprihom, precise powder, whether it is appropriate for both deployment & # 39; the instrument as well as the mole penetration & # 39; the experiment of heat flux under our face. "

Once the sites on the Martian surface are carefully selected for two main instruments, the team will stop and start initial testing of the mechanical arm that will put them there.

Data downloaded from landing also indicates that during its first full day in & # 39; Mars, the spacecraft turns from Insight solar generated more power than any vehicle & # 39; advance on the surface & # 39; Mars.

"It's great to have the first" off the record "our world in our first full day on Mars," said Hoffman. "But even better than the achievement of generation & # 39; more electricity than any mission ahead is what it stands for to carry out the tasks of the following engineering. The 4588 watt that produced hour during the sol 1 means that currently we have more than enough juice to perform these tasks and we & # 39; forward with our science mission. "

Launched from Vandenberg Air Force Base in & # 39; & # 39 California 5; May, Insight will operate on the surface Martja for one year, along with & # 39; 40 Martian days, or the equivalent of SOLS & # 39; nearly two Earth years. Insight will study the deep interior & # 39; Mars to learn how all the celestial bodies with & # 39; rock surfaces, including the Earth and the Moon, formed.
