From the amazing Apollo Moon landings that first put people on the Moon, to using the Hubble Space Telescope to look deep into the universe, NASA has always helped us learn more and go further than ever before. The agency is famous for its missions that study our Earth, other planets, and faraway galaxies. This work gives us vital information to help understand big issues like climate change, how planets are formed, and the mysteries of the stars.

This article focuses about InSight Mars Lander which aims on Mars (Elysium Planitia), gathering key information to better understand its current role in ongoing research and spaceflight.

  • NASA’s InSight Mars Lander lifted off on May 5, 2018, embarking on a critical journey beyond Earth.  
  • With a clearly defined scientific objective—namely, to Study Martian interior: crust, mantle, core; tectonic activity—the team is poised to gather unprecedented data and significantly advance our understanding.  
  • As a specific Mars lander (geophysical station), its main goal was clearly defined, and everyone involved worked hard and stayed focused on achieving it.  
  • The advanced technology of the Atlas V 401 made it a very capable choice for this demanding space mission. 
  • Liftoff occurred at Vandenberg AFB, SLC-3E, kicking off the mission. 
  • Over 4 Earth years was the length of the mission from launch to completion. 
  • This effort was undertaken solely by NASA. 
  • Final status of the mission: Completed (Successful, mission ended due to power loss). 
  • Estimated at ~$830 million (including launch and operations), InSight Mars Lander represents a significant investment in next-generation space exploration technologies. 

InSight Mars Lander is equipped with SEIS (seismometer), HP3 (heat probe), RISE (rotation/interior structure) to support scientific innovation and real-time decision-making in space.

Past UPCS Prelims PYQs on NASA Space Missions

Q1 [2022]: Which one of the following statements best reflects the idea behind the “Fractional Orbital Bombardment System” often talked about in the media?

(a) A hypersonic missile is launched into space to counter the asteroid approaching the Earth and explode it in space.

(b) A spacecraft lands on another planet after making several orbital motions.

(c) A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.

(d) A spacecraft moves along a comet with the same speed and places a probe on its surface.

Answer: (c) A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.

Explanation: While this question pertains to a military concept, NASAs research into orbital mechanics and space trajectories contributes to the broader understanding of such technologies.

Q2 [2020]: “The experiment will employ a trio of spacecraft flying in formation in the shape of an equilateral triangle that has sides one million kilometres long, with lasers shining between the craft.” The experiment in question refers to:

(a) Voyager-2

(b) New Horizons

(c) Lisa Pathfinder

(d) Evolved LISA

Answer: (d) Evolved LISA

Explanation: Evolved LISA (Laser Interferometer Space Antenna) is a space-based gravitational wave observatory developed by ESA with contributions from NASA.

Q3 [2017]: What is the purpose of ‘evolved Laser Interferometer Space Antenna (eLISA)’ project?

(a) To detect neutrinos

(b) To detect gravitational waves

(c) To detect the effectiveness of missile defence system

(d) To study the effect of solar flares on our communication systems

Answer: (b) To detect gravitational waves

Explanation: Evolved Laser Space Interferometer Space Antenna (ELISA) project was widely in the news due to the discovery of gravitational waves by the LIGO detector and the subsequent success of the LISA pathfinder project. The European Space Agency is leading the ELISA mission. The project is initiated to detect and accurately measure gravitational waves.

Q4 [2016]: What is ‘Greased Lightning-10 (GL-10)’, recently in the news?

(a) Electric plane tested by NASA

(b) Solar-powered two-seater aircraft designed by Japan

(c) Space observatory launched by China

(d) Reusable rocket designed by ISRO

Answer: (a) Electric plane tested by NASA
educationprovince.com

Explanation: GL-10 is a remotely piloted plane similar to an Unmanned Aerial Vehicle (UAV). It is designed and developed in such a way that it can take off like a helicopter and fly like an airplane. It is a battery-powered 10-engine with a wingspan of 3.05 meters. Eight electric motors are mounted on the wings. 2 electric motors are mounted on the tail. It weighs a maximum of 28.1 kilograms at takeoff. Due to its versatile vertical takeoff and landing ability, it produces less noise. It can be used as a UAV for small package delivery or vertical takeoff and landing, as well as long-endurance surveillance for agriculture, mapping, and other applications. Its modified scaled-up version can be used as a persons air vehicle.

Q5 [2015]: The term ‘Goldilocks Zone’ is often seen in the news in the context of:

(a) The limits of habitable zone above the surface of the Earth

(b) Regions inside the Earth where shale gas is available

(c) Search for the Earth-like planets in outer space

(d) Search for meteorites containing precious metals

Answer: (c) Search for the Earth-like planets in outer space

Explanation: The Goldilocks Zone is the livable zone around a star where the temperature is not too hot and not too cold for liquid water to exist on a planet. It is a metaphor for the childrens story Goldilocks and the Three Bears, in which a young girl selects from sets of three objects, eschewing the extremes (such as those that are enormous or small, hot or cold) and fixing on the one that is just right in the middle. The Goldilocks zone of the Sun surrounds the Earth. All of Earths water would freeze if it were found where the dwarf planet Pluto is; however, all of Earths water would boil out if it were found where Mercury is.

1. Sun
2. Neptune
3. Saturn
4. Jupiter
Answer: 3
Solution: The correct answer is Saturn. The Cassini-Huygens mission, commonly called Cassini, sent a probe to study the planet Saturn. It was the first to orbit Saturn and even the first one to land in the outer solar system. Cassini-Huygens was a collaboration between NASA, the European Space Agency, and the Italian Space Agency.

1. Chandrayan - 2
2. Mangalyan
3. Pioneer - 1
4. Pioneer - 10
Answer: 3
Solution: The correct answer is Pioneer - 1. The first space ship sent out of the solar system was Pioneer - 1. Pioneer-1 was launched in October 1958. It was a 38-kilogram spacecraft launched into space by NASA. It carried aboard a two-stage rocket namely the Thor-Able I, an early predecessor of the modern Delta rockets. It was lifted off from a launchpad at Kennedy Space Launch Centre.

Q3. Which one of the following belongs to India's inter-planetary mission?
1. SARAL
2. Jugnu
3. Mangalyaan
4. ANUSAT
Answer: 3
