Nasa blasts off Mars-bound spacecraft to study quakes
CALIFORNIA: Nasa on Saturday launched its latest Mars lander, called Insight, designed to perch on the surface and listen for “Marsquakes” ahead of eventual human missions to explore the Red Planet.
“Three, two, one, liftoff!” said a Nasa commentator as the unmanned spacecraft blasted off on a dark, foggy morning atop an Atlas V rocket at 4:05 am Pacific time from Vandenberg Air Force Base in California, marking Nasa’s first interplanetary launch from the US west coast.
The $993-million project aims to expand human knowledge of interior conditions on Mars, inform efforts to send explorers there and reveal how rocky planets like the Earth formed billions of years ago.
“This is a big day. We are going back to Mars,” said Nasa administrator Jim Bridenstine after the launch.
“It is important for our country. It is also important for the world and it really establishes American leadership in a lot of ways.”
About an hour and 40 minutes into the flight, the spaceship separated from the upper stage of the rocket, as planned.
“I’m on my own now,” said the US space agency Twitter account.
“This marks the beginning of my six-month journey to #Mars.”
If all goes well during the 301-million mile trip, the lander should settle on the Red Planet on November 26. Insight is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. Nasa chief scientist Jim Green said experts already know that Mars has quakes, avalanches and meteor strikes.
“But how quake-prone is Mars? That is fundamental information that we need to know as humans that explore Mars,” Green said.
The key instrument on board is a seismometer, called the Seismic Experiment for Interior Structure, made by the French Space Agency.
