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.

UPSC Practice Questions on NASA Space Missions

Q1. Consider the following statements
1. The NewSpace India Limited is the commercial arm of the Department of Space
2. Indian National Space Promotion and Authorisation Center IN-SPACe will facilitate the participation of private sector
Which of the above is/are correct?
1. 1 only
2. 2 only
3. Both 1 and 2
4. Neither 1 nor 2
Answer: 3
Solution: The new Indian National Space Promotion and Authorisation Center IN-SPACe, which is expected to be functional within six months, will assess the needs and demands of private players, including educational and research institutions, and explore ways to accommodate these requirements in consultation with ISRO. Existing ISRO infrastructure, both ground- and space-based, scientific and technical resources, and even data are planned to be made accessible to interested parties to enable them to carry out their space-related activities.

It is not that there is no private industry involvement in Indias space sector. In fact, a large part of the manufacturing and fabrication of rockets and satellites now happens in the private sector. There is increasing participation of research institutions as well. But as Sivan told this newspaper on Thursday, the Indian industry had a barely three per cent share in a rapidly growing global space economy which was already worth at least 360 billion dollars. Only two per cent of this market was for rocket and satellite launch services, which require fairly large infrastructure and heavy investment. The remaining 95 per cent related to satellite-based services, and ground-based systems.

Indian industry, however, is unable to compete, because till now its role has been mainly that of suppliers of components and sub-systems. Indian industries do not have the resources or the technology to undertake independent space projects of the kind that US companies such as SpaceX have been doing or provide space-based services.

Additionally, the demand for space-based applications and services is growing even within India, and ISRO is unable to cater to this. The need for satellite data, imageries and space technology now cuts across sectors, from weather to agriculture to transport to urban development and more. As Sivan told this newspaper, ISRO would have to be expanded 10 times the current level to meet all the demand that is arising.

At the same time, there were several Indian companies waiting to make use of these opportunities. Sivan said there were a few companies that were in the process of developing their own launch vehicles, the rockets like ISROs PSLV that carry the satellites and other payloads into space, and ISRO would like to help them do that. Right now, all launches from India happen on ISRO rockets, the different versions of PSLV and GSLV. Sivan said ISRO was ready to provide all its facilities to private players whose projects had been approved by IN-SPACe. Private companies, if they wanted, could even build their own launchpad within the Sriharikota launch station, and ISRO would provide the necessary land for that, he said.

IN-SPACe is supposed to be a facilitator, and also a regulator. It will act as an interface between ISRO and private parties and assess how best to utilize Indias space resources and increase space-based activities.
