Static background & why it matters
Historically, space exploration was a domain almost exclusively controlled by national governments and their agencies, driven by geopolitical competition and scientific pursuit. The late 20th and early 21st centuries witnessed a paradigm shift, with private entities increasingly entering the space sector, driven by technological advancements, reduced costs, and the potential for commercial exploitation. This shift is underpinned by evolving national space policies that encourage private participation and public-private partnerships.
The increasing involvement of private companies like SpaceX and Blue Origin is transforming the global space industry. UPSC cares about this shift as it impacts technological innovation, economic growth, job creation, national strategic capabilities, and the future direction of space exploration, including the potential for space tourism and resource utilization. It also highlights the evolving models of public-private partnerships in critical sectors.
- NewSpace
- A term referring to the emerging private spaceflight industry, characterized by innovative business models, lower costs, and rapid development cycles, contrasting with traditional government-led space programs.
- Space Economy
- Encompasses all activities and the use of resources that create and provide value and benefits to human beings in the course of exploring, understanding, and utilizing space.

With reference to ‘Astrosat’, the astronomical observatory launched by India, which of the following statements is/are correct?
1. Other than the USA and Russia, India is the only country to have launched a similar observatory into space.
2. Astrosat is a 2000 kg satellite placed in an orbit at 1650 km above the surface of the Earth.
Statement 1 is incorrect: AstroSat is India's first dedicated multi-wavelength space observatory aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously. India is the 5th country to join the space observatory elite list after the USA, Russia, Japan, and Europe. Statement 2 is incorrect: AstroSat with a lift-off mass of about 1513 kg was launched into a 650 km orbit inclined at an angle of 6 degrees to the equator by PSLV-C30. Therefore, option D is the correct answer.
Consider the following statements regarding: The Mangalyaan launched by ISRO
1. is also called the Mars Orbiter Mission
2. made India the second country to have a spacecraft orbit the Mars after USA
3. made India the only country to be successful in making its spacecraft orbit the Mars in its very first attempt
Which of the statements given above is/are correct?
Statement 1 is correct: Mangalyaan is also called the Mars Orbiter Mission (MOM). This was its official designation. Statement 2 is incorrect: India was not the second country to orbit Mars. Several countries had successfully sent spacecraft to Mars before Mangalyaan, including the USA, Russia, and the European Space Agency (ESA). Statement 3 is correct: India was indeed the only country at that time to succeed in placing a spacecraft into Martian orbit on its very first attempt. This was a significant achievement for ISRO. Hence, option C is the correct answer.
In which of the following activities are Indian Remote Sensing (IRS) satellites used?
1. Assessment of crop productivity
2. Locating groundwater resources
3. Mineral exploration
4. Telecommunications
5. Traffic studies
Select the correct answer using the code given below
Assessment of crop productivity: IRS satellites capture data that helps assess crop health, growth stage, and potential yield.
Locating groundwater resources: Remote sensing allows for studying geological features and identifying potential zones with underground water reserves.
Mineral exploration: IRS data can reveal signatures of specific minerals on the Earth's surface, aiding in mineral exploration activities.
Telecommunications: IRS satellites are not designed for telecommunication purposes. Geostationary satellites are typically used for this function.
Traffic studies: While remote sensing can be used for some traffic studies (e.g., analyzing transportation infrastructure), it's not the primary application of IRS satellites. Therefore, only 1,2 and 3 are primary applications of IRS satellites.
“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
The description mentions three spacecraft in an equilateral triangle formation with million-kilometre sides using lasers for measurement.
This matches the design of the Evolved Laser Interferometer Space Antenna (eLISA) mission.
eLISA is a proposed space observatory aiming to detect gravitational waves using precisely positioned spacecraft. Voyager-2 and New Horizons are single spacecraft on exploration missions, not designed for gravitational wave detection. LISA Pathfinder was a precursor mission to test technologies for eLISA, not the full mission itself. Therefore, based on the details provided, the experiment refers to the Evolved LISA mission.

Pair 3 is correctly matched: These twin NASA spacecraft were launched in 1977 to conduct a "Grand Tour" of the outer planets. They provided detailed images and data on Jupiter, Saturn, Uranus, and Neptune and are now continuing their journey into interstellar space.
With reference to radioisotope thermoelectric generators (RTGs), consider the following statements:
1. RTGs are miniature fission reactors.
2. RTGs are used for powering the onboard systems of spacecrafts.
3. RTGs can use Plutonium-238, which is a by-product of weapons development.
Which of the statements given above are correct?
* Statement 1: Incorrect. RTGs (Radioisotope Thermoelectric Generators) are not miniature fission reactors. Fission reactors use nuclear fission, a process of splitting atoms to release a tremendous amount of energy. RTGs, on the other hand, utilize the natural radioactive decay of isotopes to generate heat, which is then converted to electricity through a process called thermoelectricity. * Statement 2: Correct. RTGs are indeed a reliable power source for spacecraft, especially those venturing far from the sun where solar panels become ineffective. They provide consistent, low-level electric power for extended periods, making them ideal for probes, satellites, and rovers in deep space. * Statement 3: Correct. Plutonium-238 is a common isotope used in RTGs due to its long half-life (the time it takes for half of the material to decay) and its ability to generate a steady heat output from its decay process. While it can be a byproduct of weapons development, there are also alternative ways to produce Plutonium-238 specifically for peaceful applications like RTGs.
