NASA is a leader in working with other countries in space, partnering with over 100 nations. When NASA works with big international space groups like ESA (Europe), JAXA (Japan), and ISRO (India), it shows that more and more countries are cooperating peacefully in space. This teamwork is really important for tackling problems that affect everyone, like protecting Earth from asteroids or cleaning up space junk.

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

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.

UPSC Practice Questions on NASA Space Missions

Q1. Landsat 9 is a joint mission of which of the following organizations?
1. National Aeronautics and Space Administration and European Space Agency
2. National Aeronautics and Space Administration and US Geological Survey
3. European Space Agency and US Geological Survey
4. National Aeronautics and Space Administration and Indian Space Research Organisation
Answer: option 2
Solution: Landsat 9 is a joint mission of NASA and the US Geological Survey. Recently, NASA has launched an earth monitoring satellite called Landsat 9 from Vandenberg Space Force Base in California. The satellite is referred to as NASA's new eye in the sky that will help study climate change. Landsat-9 is the continuation of a series of Earth-observing spacecraft stretching back almost 50 years. The first Landsat satellite was launched in 1972 and since then, Landsat satellites have collected images of earth and helped understand how land usage has changed over the decades. In 2008, it was decided that all Landsat images will be free and publicly available and the policy has helped scores of researchers, farmers, policy analysts, glaciologists, and seismologists. Landsat images have been used to study the health of forests, coral reefs, monitor water quality and melting glaciers. The Landsat 9 joins Landsat 8 that was launched in 2013 and the satellites together will collect images of Earth’s surface. It takes 8 days to capture the whole Earth. Landsat 9 carries instruments similar to the other Landsat satellites, but it is the most technologically advanced satellite of its generation. The instruments aboard Landsat 9 are the Operational Land Imager 2 and the Thermal Infrared Sensor 2. OLI-2 captures sunlight reflected off Earth’s surface and studies the visible, near-infrared, and short wave infrared portions of the spectrum. TIRS-2 has a four-element refractive telescope and photosensitive detectors that capture thermal radiation and help study the Earth’s surface temperature. Along with the European Union’s Sentinel-2 satellites, the Landsat Satellite will provide better estimation of the extent of climate change.
