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.

Woman, 2 sons found dead in Delhi home; suicide suspected
New Delhi (PTI): Three members of a family were found dead inside their home in southeast Delhi's Kalkaji on Friday, with police suspecting it to be a case of suicide, officials said.
Police said the incident came to light around 2.47 pm when a police team reached the premises to execute a court order related to possession of the property. When repeated knocks went unanswered, the staff used a duplicate key to open the door.
Inside, officers found Anuradha Kapoor (52) and her sons, Ashish Kapoor (32) and Chaitanya Kapoor (27), hanging from the ceiling, Deputy Commissioner of Police (Southeast) Hemant Tiwari said in a statement. All three were declared dead.
A handwritten note was recovered from the room, suggesting the family had been struggling with depression.
"The handwritten note indicates emotional distress faced by the family due to which the family may have taken the extreme step," the officer said.
The bodies have been shifted to the All India Institute of Medical Sciences (AIIMS) mortuary for post-mortem and other legal formalities under Section 194 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), police said.
Residents of the neighbourhood said they were shocked to learn about the deaths, adding that the family kept largely to themselves.
Pankaj Kashyap, a resident of Girinagar, said he learnt about the deaths while leaving for work. "I live and work here and was leaving for work when I saw many people standing outside and talking. That is how I got to know that three people had committed suicide. I also saw several police vehicles outside, but I do not know much beyond that," he said.
Baldev, another neighbour, said the family had been living in the newly constructed house for around two years. "We only knew that a mother and her two children lived there. They had moved into the newly built house around two years ago. We did not interact much with them. Today we heard that all three have committed suicide, and whatever we know is based on what people here are saying," he said.
Another neighbour, Ramesh Kumar, claimed the family had earlier attempted suicide.
"About fifteen to twenty days ago, the two sons in the family had attempted suicide and police and ambulances had come. That was when I first got to know who they were. I do not recognise them by face, but we saw the ambulances and police take the two sons that day. Today again we saw ambulances and police arriving, so everyone came out to see what had happened. I do not know how long they had been living here, but this is all we know," he said.
Police said they are examining the family's financial condition, social circumstances, and other factors that may have contributed to the incident. Further investigation is underway.
