Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight)
InSight mission is a robotic lander designed to study the deep interior of the planet Mars.
The spacecraft was launched on 5 May 2018 at 11:05 UTC on an Atlas V 401 launch vehicle.
It took 6.5 months across 484 million km (301 million mi) for a touchdown on 26 November 2018 Landing successfully.
InSight's payload has a total mass of 50 kg.
It will take precise measurements of marsquakes and other internal activity on Mars.
It will also investigate how the Martian crust and mantle respond to the effects of meteorite impacts.
The seismometer will also detect sources including atmospheric waves and gravimetric signals (tidal forces) from Mars' moon Phobos, up to high frequency seismic waves of 50 Hz.
It has a suite of air temperature, wind speed and wind direction sensors.
A self-penetrating heat flow probe. It was designed to burrow as deep as 5 m (16 ft) below the Martian surface while trailing a tether with embedded heat sensors to measure how efficiently heat flows through Mars' core, and thus reveal unique information about the planet's interior and how it has evolved over time.
Instrument Deployment Arm (IDA) is a 2.4 m robotic arm that will be used to deploy the SEIS and HP3 instruments to Mars' surface. It also features the IDC camera.
InSight has a chip in which an electron beam was used to etch letters only 1⁄1000 the width of a human hair onto 8 mm (0.3 in) silicon wafers. The chip contains 4 billion people names, two rounds of sign-ups were conducted totaling 2.4 million names: 826,923 names were registered in 2015 and a further 1.6 million names were added in 2017.
History Of InSight:-
The mission launched on 5 May 2018 at 11:05 UTC aboard an Atlas V-401 rocket and successfully landed at Elysium Planitia on Mars on 26 November 2018 at 19:52:59 UTC.
InSight traveled 483 million km (300 million mi) during its journey.
Features OF InSight
InSight's mission is to place a seismometer, called SEIS, on the surface of Mars to measure seismic activity and provide accurate 3D models of the planet's interior and to measure internal heat flow using a heat probe called HP3 to study Mars' early geological evolution.
The seismometer on both Viking spacecraft was mounted on the lander, which meant that it also picked up vibrations from various operations of the lander and from the wind.
The Viking 2 seismometer detected pressure from the Mars winds complementing the meteorology results.
Cost Of this InSight mission total of US$830 million.
The InSight mission placed a single stationary lander on Mars to study its deep interior and address a fundamental issue of planetary and Solar System science: understanding the processes that shaped the rocky planets of the inner Solar System (including Earth) more than four billion years ago.
By studying the size, thickness, density and overall structure of Mars' core, mantle and crust, as well as the rate at which heat escapes from the planet's interior, InSight will provide a glimpse into the evolutionary processes of all of the rocky planets in the inner Solar System.
InSight mission's goal is to improve the understanding of this process and, by extension, terrestrial evolution, by measuring the planetary building blocks shaped by this differentiation: a terrestrial planet's core, mantle and crust.
The mission will determine if there is any seismic activity, measure the rate of heat flow from the interior, estimate the size of Mars' core and whether the core is liquid or solid.
The mission's secondary objective is to conduct an in-depth study of geophysics, tectonic activity and the effect of meteorite impacts on Mars, which could provide knowledge about such processes on Earth.
In terms of fundamental processes shaping planetary formation, it is thought that Mars contains the most in-depth and accurate historical record, because it is big enough to have undergone the earliest accretion and internal heating processes that shaped the terrestrial planets, but is small enough to have retained signs of those processes.
Design Of InSight
Total: 694 kg (1,530 lb)
About 6.0 m (19.7 ft) wide with solar panels deployed. The science deck is about 1.56 m (5.1 ft) wide and between 0.83 and 1.08 m (2.7 and 3.5 ft) high (depending on leg compression after landing). The length of the robotic arm is 2.4 m (7.9 ft)
Power is generated by two round solar panels, each 2.15 m (7.1 ft) in diameter and consisting of SolAero ZTJ triple-junction solar cells made of InGaP/InGaAs/Ge arranged on Orbital ATK UltraFlex arrays. After touchdown on the Martian surface, the arrays are deployed by opening like a folding fan.
The spacecraft was launched on 5 May 2018 at 11:05 UTC on an Atlas V 401 launch vehicle (AV-078) from Vandenberg Air Force Base Space Launch Complex 3-East. This was the first American interplanetary mission to launch from California.
The launch was managed by NASA's Launch Services Program.
The journey to Mars took 6.5 months across 484 million km (301 million mi) for a touchdown on 26 November. Landing successfully, a three-month-long deployment phase commenced as part of its two-year (about one Martian year) prime mission.
Team and participation
The InSight science and engineering team includes scientists and engineers from many disciplines, countries and organizations. The science team assigned to InSight includes scientists from institutions in the U.S., France, Germany, Austria, Belgium, Canada, Japan, Switzerland, Spain, Poland and the United Kingdom.
As part of its public outreach, NASA organized a program where members of the public were able to have their names sent to Mars aboard InSight. Due to its launch delay, two rounds of sign-ups were conducted totaling 2.4 million names: 826,923 names were registered in 2015 and a further 1.6 million names were added in 2017.
An electron beam was used to etch letters only 1⁄1000 the width of a human hair onto 8 mm (0.3 in) silicon wafers.
The first chip was installed on the lander in November 2015 and the second on 23 January 2018
