NASA: Insight Spacecraft On Voyage To Mars

New York: Propelled by a predawn rocket launch from California, Nasa’s InSight spacecraft is now on a voyage of some six months to Mars to study the deep interior of the red planet.

“The science that we want to do with this mission, the reason we’re going to Mars, is really the science of understanding the early solar system,” said Bruce Banerdt, the principal investigator in a pre-launch briefing on Thursday. “How planets form, how rocky planets form.” It could also provide insights to planets around distant stars and how likely those possess climates and conditions that would be habitable to life.

An Atlas 5 rocket carrying InSight lifted off at 7.05am Eastern time from a foggy Vandenberg Air Force Base lighting up the skies as it headed upward on a southward arc, visible to early risers in Los Angeles and San Diego.

After a journey of 300 million miles, InSight – the name is a shortening of Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport – will head for the surface of Mars on November 26. If all goes well, a heat shield, parachutes and a rocket engine will slow InSight to a safe landing in a flat plain just north of the Martian equator.

The main mission of InSight is essentially to take a sonogram of Mars. Just as sound waves can reveal the outlines of a baby within a mother, the seismic rumblings of quakes on Mars will reveal the planet’s interior structure – the size of the core, the thickness of the crust, the properties of the mantle.
