We have lift off! NASA successfully launches InSight Mars probe

A robot armed with a hammer and quake monitor is rocketing towards Mars — aiming to reveal its internal secrets and discover whether it was ever home to life.

In a twist, NASA launched the Mars InSight lander from California rather than Florida’s Cape Canaveral. 

It was the first interplanetary mission ever to depart from the West Coast, drawing pre-dawn crowds to Vandenberg Air Force Base and rocket watchers down the California coast into Baja.

The spacecraft will take more than six months to get to Mars and start its unprecedented geologic excavations, traveling 300 million miles (485 million kilometers) to get there.

InSight will dig deeper into Mars than ever before – nearly 16 feet, or 5 meters – to take the planet’s temperature. 

It will also attempt to make the first measurements of marsquakes, using a high-tech seismometer placed directly on the Martian surface.

Also aboard the Atlas V rocket: a pair of mini satellites, or CubeSats, meant to trail InSight all the way to Mars in a first-of-its-kind technology demonstration.

The $1 billion (£738.8million) mission involves scientists from the U.S., France, Germany and elsewhere in Europe.

‘I can’t describe to you in words how very excited I am … to go off to Mars,’ said project manager Tom Hoffman from NASA’s Jet Propulsion Laboratory in Pasadena, California. ‘It’s going to be awesome.’

NASA hasn’t put a spacecraft down on Mars since the Curiosity rover in 2012. 

The U.S. is the only country to successfully land and operate a spacecraft at Mars. 

Only 40 per cent of all missions to Mars from all countries – orbiters and landers alike – have proven successful over the decades.

If all goes well, the three-legged InSight will descend by parachute and engine firings onto a flat equatorial region of Mars – believed to be free of big, potentially dangerous rocks – on Novembe 26. 

InSight will travel over 300M miles in space to reach Mars's atmosphere. It is scheduled to launch in the early morning hours of Saturday, May 5, and land on Mars six months later

InSight will be released about 90 minutes after launch on a 301 million-mile flight to Mars, and is due to reach its destination six months later, landing on a flat, smooth plain close to the planet's equator called the Elysium Planitia

WHAT IS THE NASA MARS INSIGHT PROBE?

InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is scheduled to launch on Saturday, May 5, and land on Mars six months later.

A slender cylindrical probe dubbed the mole is designed to tunnel nearly 16 feet (five metres) into the Martian soil.

A quake-measuring seismometer, meanwhile, will be removed from the lander by a mechanical arm and placed directly on the surface for better vibration monitoring.

InSight is actually two years late flying because of problems with the French-supplied seismometer system that had to be fixed.

The 1,530-pound (694 kg) InSight builds on the design of the Phoenix lander and, before that, the Viking landers. 

They’re all stationary three-legged landers, so not equipped to roam around. 

Once down, it will stay put, using a mechanical arm to place the science instruments on the surface.

‘This mission will probe the interior of another terrestrial planet, giving us an idea of the size of the core, the mantle, the crust and our ability then to compare that with the Earth,’ said NASA’s chief scientist Jim Green. 

‘This is of fundamental importance to understand the origin of our solar system and how it became the way it is today.’

The 794-pound lander, which is about the size of a garden table, will launch aboard a powerful, 19-story Atlas V rocket, which will also carry two CubeSat miniature satellites (pictured) that will follow InSight to Mars to test deep-space communications technology

InSight’s chief scientist, Bruce Banerdt of JPL, said Mars is ideal for learning how the rocky planets of our solar system formed 4.5 billion years ago. 

Unlike our active Earth, Mars hasn’t been transformed by plate tectonics and other processes, he noted.

Over the course of two Earth years – or one Martian year – scientists expect InSight’s three main experiments to provide a true 3-D image of Mars.

The lander is equipped with a seismometer for measuring marsquakes, a self-hammering probe for burrowing beneath the surface, and a radio system for tracking the spacecraft’s position and planet’s wobbly rotation, thereby revealing the size and composition of Mars’ core.

‘InSight, for seismologists, will really be a piece of history, a new page of history,’ said the Paris Institute of Earth Physics’ Philippe Lognonne, lead scientist of the InSight seismometer.

Problems with the French-supplied seismometer kept InSight from launching two years ago.

NASA normally launches from Cape Canaveral, but decided to switch to California for InSight to take advantage of a shorter flight backlog. 

This was the first U.S. interplanetary mission to launch from somewhere other than Cape Canaveral.   

WHAT ARE MARSQUAKES AND HOW WILL NASA’S INSIGHT MISSION DETECT THEM? 

Starting next year, scientists will get their first look deep below the surface of Mars.  

Nasa’s robotic lander InSight will study marsquakes to learn about the Martian crust, mantle and core. Doing so could help answer a big question: how are planets born? 

Seismology, the study of quakes, has already revealed some of the answers here on Earth, but our planet has been churning its geologic record for billions of years, hiding its most ancient history.

Mars, at half the size of Earth, churns far less – it’s a fossil planet, preserving the history of its early birth.

When rocks crack or shift, they give off seismic waves that bounce throughout a planet. These waves, better known as quakes, travel at different speeds depending on the geologic material they travel through.

Starting next year, scientists will get their first look deep below the surface of Mars.This  artist’s rendition showing the inner structure of Mars. The topmost layer is known as the crust, underneath it is the mantle, which rests on an inner core

Seismometers, like InSight’s SEIS instrument, measure the size, frequency and speed of these quakes, offering scientists a snapshot of the material they pass through.

Mars’ geologic record includes lighter rocks and minerals, which rose from the planet’s interior to form the Martian crust, and heavier rocks and minerals that sank to form the Martian mantle and core. 

By learning about the layering of these materials, scientists can explain why some rocky planets turn into an ‘Earth’ rather than a ‘Mars’ or ‘Venus’ – a factor that is essential to understanding where life can appear in the universe.

Each time a quake happens on Mars, it will give InSight a ‘snapshot’ of the planet’s interior. The InSight team estimates the spacecraft will see between a couple dozen to several hundred quakes over the course of the mission.

Small meteorites, which pass through the thin Martian atmosphere on a regular basis, will also serve as seismic ‘snapshots.’
