NASA mission to study interior of Mars set for Saturday launch
Washington, May 5 : NASA is all set to launch on Saturday the first mission designed to study the deep interior of Mars called the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight).
It will launch at 7.05 a.m. (4.35 p.m. India time) aboard a United Launch Alliance (ULA) Atlas V rocket from California's Vandenberg Air Force Base.
"Live coverage will begin at 6:30am with all the details about this mission to take the Red Planet's 'vital signs'," NASA said in a tweet.
"I'm excited for this mission to go beneath the surface of Mars to explore its crust, mantle and core -- as well as marsquakes," NASA's 13th Administrator Jim Bridenstine tweeted on Friday.
The ULA rocket will carry the spacecraft over the Channel Islands just off the California Coast and continue climbing out over the Pacific, shadowing the coastline south beyond Baja California in Mexico.
InSight's Atlas will reach orbit about 13 minutes after launch, when the rocket is about 1,900 kilometres northwest of Isabella Island, Ecuador, NASA said in a statement.
InSight will study the deep interior of Mars to learn how all rocky planets formed, including Earth and its Moon.
The lander's instruments include a seismometer to detect marsquakes, and a probe that will monitor the flow of heat from the planet's interior.
InSight will be the first mission to peer deep beneath the Martian surface, studying the planet's interior by measuring its heat output and listening for marsquakes, which are seismic events similar to earthquakes on Earth.
It will use the seismic waves generated by marsquakes to develop a map of the planet's deep interior.

Confident we are going to win Kerala: Shashi Tharoor
New Delhi (PTI): Congress leader Shashi Tharoor on Thursday expressed confidence in the victory of the United Democratic Front (UDF) in Kerala, saying the Congress-led alliance will win more than 75 seats out of the total 140 in the state.
Tharoor, who hails from Kerala, said he was not surprised to see the results of the exit polls, most of which predicted a victory for the UDF that has been out of power for 10 years in the state.
"We have been on the ground. I have campaigned in 59 constituencies across 12 districts out of 14. I was very confident we are going to win.
"Everything that I have picked up from not just my party colleagues and workers but also from other observers, media and others have always convinced me that we were going to score a comfortable win of above 75 seats. And all the (exit) polls have confirmed the same thing," he told reporters here.
The Thiruvananthapuram MP said he was not surprised to see the results of the exit polls but in general he was not a big fan of exit polls in India.
"Because ours is not purely a homogenous society. We have to take into account gender issue, caste issue, class issue, regional disparities. You never get a convincingly large enough sample to give an accurate poll and now there is the additional complication that we have heard about in West Bengal this year that many people are unwilling to answer the questions of the pollsters," he said.
The Congress leader said normally, it used to be below 10 per cent that people said that they would not answer.
"Even if you are a reputable exit pollster, in Bengal, one polling company has said 60 per cent of people refused to answer. So, what is the worth of a poll where 60 per cent of your respondents have not answered," he said.
Several exit polls on Wednesday predicted a comeback by the Congress-led UDF in Kerala after 10 years, dethroning the CPI(M)-led Left Democratic Front (LDF).
Polling for the 140-member Kerala assembly was held on April 9. Results of assembly elections in West Bengal, Tamil Nadu, Assam, Puducherry, besides Kerala, will be announced on May 4.
