(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.

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.

(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. The Parker Solar Probe Mission sometimes mentioned in the news recently is related to
1. Indian Space Research Organisation
2. National Aeronautics and Space Administration
3. European Space Agency
4. Japan Aerospace Exploration Agency
Answer: National Aeronautics and Space Administration
Solution: In News: Scientists using data from NASA's Parker Solar Probe have assembled the most complete picture yet of the inner structure and behaviour of the large cloud of space dust, known as the zodiacal cloud, that swirls throughout the solar system.

Key Points:
They found three dust populations in the cloud:
Most of the grains are being slowly pulled in toward the Sun alpha-meteoroids.
The second population is generated as grains in the swirling cloud collide, creating fragments so small that they are pushed out of the solar system in all directions by pressure from sunlight beta-meteoroids.
A third group, probably created when a tube of cometary debris collides with grains from the first two populations, is scattered out in a distinctive wedge shape.
Zodiacal clouds:
The sources of zodiacal clouds/interplanetary dust particles IDPs include at least: asteroid collisions, cometary activity and collisions in the inner Solar System, Kuiper belt collisions, and interstellar medium grains.
About the mission:
NASA's historic Parker Solar Probe mission will revolutionize our understanding of the sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds.
Parker Solar Probe will travel through the sun's atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions and ultimately providing humanity with the closest-ever observations of a star.

Key Points:
Landsat-9:
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.
About Landsat 9:
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 OLI-2 and the Thermal Infrared Sensor 2 TIRS-2.
OLI-2: It captures sunlight reflected off Earth's surface and studies the visible, near-infrared, and short wave infrared portions of the spectrum.
TIRS-2: It 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.
