The InSight Rover NASA successfully landed on Mars

Yesterday, NASA's InSight lander touched down successfully on the martian surface in a flawless feat of engineering.

Now that InSight is on the ground, the company's role in the mission is done, but Wilson said the real payoff is when the scientific data starts coming back.

"Although we've done it before, landing on Mars is hard, and this mission is no different", Rob Manning, NASA's chief engineer at the jet propulsion laboratory, said in a statement.

Ukrainian president asks Trump to deliver pointed message to Putin
Trump is due to meet Putin on the sidelines of the G20 summit in Buenos Aires, which convenes on Friday and Saturday. But losses were limited by expectations that crude exporters would agree to cut output at an upcoming OPEC meeting.

"The reason why we're digging into Mars is to better understand not just Mars, but the Earth itself", said JPL's Bruce Banerdt, InSight's principal investigator. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.

NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission's primary objective will be to drill down below the Martian surface, taking temperature and seismology measurements to shed new light on activity of the red planet's core, mantle and crust with three unique instruments. The experiment which will map the interior structure of Mars and measure its rotation was developed in the United States. Just six minutes before it attempts a landing, it will have been traveling at 14,100 miles per hour. "We are well on our way to thoroughly investigate what's inside of Mars for the very first time".

Confirmation of a successful touchdown is not the end of the challenges of landing on the Red Planet.

Historic ‘meaningful vote’ on Brexit deal to take place on December 11
The US president said it was a "great deal for the EU" and may leave the United Kingdom unable to trade with the US. She said: "It will be one of the most significant votes that Parliament has held for many years".

The spacecraft was launched from California in May on its almost US$1 billion mission. The MarCOs are also able to capture unique images as they pass by the Red Planet and some of its moons.

"This time, we will not only plant our flag and leave our footprints - we will establish a foundation for an eventual mission to Mars, and perhaps someday, worlds beyond". Normally, this relaying is done using the already existing spacecraft such as NASA's Mars Odyssey and Mars Reconnaissance Orbiter or the European Space Agency's Mars Express. Just north of its equator, it's also a great place for InSight's solar panels to generate power for long periods. Back then, Mars then was much warmer and wetter, and might have been capable of harbouring early life.

Professor Tom Pike, from Imperial's Department of Electrical and Electronic Engineering, is part of the Mars Insight team.

Each of the companies operate ground facilities already but will work with AWS Ground Station to augment operations. Uplinking and downlinking satellite data, AWS says, is bound to get cheaper.
