The lander will be the first mission to permanently deploy instruments directly onto Martian ground using a robotic arm.

Russian Bombings in Syria ‘May Amount To War Crime’ — Amnesty
Turkey has stepped up its criticism of Russia’s airstrikes in Syria in the wake of deadly strikes in the northwest city of Idlib. In another incident 46 people, mostly children and women, died in the basement of a building in the village of al-Ghanto.
The InSight mission is considered to be significant before NASA’s planned Mars exploration programme, which involves sending humans to the Red Planet.
Donald Trump defends his use of ‘schlonged’ in Hillary Clinton insult
When it comes to criticizing Donald Trump , Bernie Sanders may be the most eloquent of all the current presidential candidates. Lemon’s focus in this discussion was Trump’s habits of insulting his critics and making unpresidential remarks.
After landing on Mars, InSight was created to detect quakes and other seismic activities, as well as measure how much heat is being released from the planets subsurface and monitor Mars’ wobble – or variations in its orbit – as it circles the sun.

Bryant warmed up for Sunday’s game amidst even more than the usual swarm of camera phones and flashes surrounding the court. The 37-year-old Bryant dunked for the first time this season on Thursday night against the Houston Rockets.
NASA’s next mission to Mars has been delayed until at least 2018 by a broken vacuum seal on the spacecraft, and the problem could threaten the whole mission.
Technicians examine the solar-cell arrays on NASA’s InSight spacecraft inside a clean room at Lockheed Martin Space Systems, Denver. The mission would have been helpful in finding how the rocky planet formed and evolved.
Insight was expected to arrive at Mars in September to take measurements of the red planet’s interior and its atmosphere, and to take color images.
Over the next couple of months, NASA will assess options for repairing the faulty instrument, a sensitive seismometer that was provided by the French space agency, CNES. “A decision on a path forward will be made in the coming months”, said Grunsfeld in a prepared statement.
A US science satellite slated to launch to Mars in March has been grounded due to a leak in a key research instrument, NASA said on Tuesday, creating uncertainty about the future of a widely anticipated effort to study the interior of the planet.
“Gaining information about the core, mantle and crust of Mars is a high priority for planetary science, and InSight was built to accomplish this”.
The instrument causing the trouble is the Seismic Experiment for Interior Structure (SEIS), a seismometer built by France’s Centre National d’Études Spatiales (CNES).
The sensor has been developed to measure ground movement as little as the diameter of an atom. But the instrument’s sensors must operate in a vacuum with a pressure of no more than 1 microbar, and the vacuum seal failed during testing. The next opportunity to potentially launch InSight would be in May 2016, Agence France Presse reported. The officials determined that the time is limited to fix such a leak.
The upcoming Mars 2020 rover was unaffected by the InSight setback.
