In a significant development for India's space sector, ISRO is set to launch a communication satellite for a US firm on December 24. This mission, facilitated by NewSpace India Limited (NSIL), ISRO's commercial arm, underscores India's increasing prowess and reliability in the global space launch market. The satellite will be placed into a Geosynchronous Transfer Orbit (GTO) by a GSLV Mk-III rocket.

This collaboration not only strengthens India-US strategic ties but also positions India as a preferred partner for international space agencies, demonstrating its cost-effective and advanced launch capabilities. It's a clear signal of India's ambition to capture a larger share of the global space economy, which is projected to grow significantly.

More Information

Background

India's space program, spearheaded by ISRO, has evolved from a self-reliant scientific endeavor focused on national development to a significant player in the global commercial space market. Initially, ISRO's commercial activities were managed by Antrix Corporation. However, with the growing global demand and the need for greater private sector participation, NewSpace India Limited (NSIL) was established in 2019 to further commercialize ISRO's capabilities and foster a demand-driven approach.

Latest Developments

The upcoming launch of a communication satellite for a US firm by ISRO, facilitated by NSIL and using the GSLV Mk-III rocket, is a significant milestone. This mission highlights India's increasing prowess, reliability, and cost-effectiveness in the global space launch market, particularly for placing heavier satellites into Geosynchronous Transfer Orbit (GTO). It also underscores the strengthening strategic and commercial ties between India and the US in the space domain.

Practice Questions (MCQs)

1. Consider the following statements regarding India's Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III): 1. It is a three-stage launch vehicle designed to launch heavier communication satellites into Geosynchronous Transfer Orbit (GTO). 2. The vehicle's upper stage utilizes an indigenously developed cryogenic engine. 3. A satellite placed in GTO by GSLV Mk-III can directly achieve a geostationary orbit without further propulsion. Which of the statements given above is/are correct?

  • A.1 only
  • B.1 and 2 only
  • C.2 and 3 only
  • D.1, 2 and 3
Show Answer

Answer: B

Statement 1 is correct: GSLV Mk-III (now officially LVM3) is indeed a three-stage vehicle designed for launching heavier communication satellites into GTO. Statement 2 is correct: India successfully developed and uses an indigenous cryogenic engine in the upper stage of GSLV Mk-III, which was a significant technological achievement. Statement 3 is incorrect: A satellite placed in GTO (an elliptical orbit) requires its own propulsion system (onboard motors) to perform orbit raising maneuvers to achieve the final geostationary orbit (GEO), which is a circular orbit at a specific altitude. GSLV Mk-III places the satellite into GTO, from where the satellite itself takes over to reach GEO.

2. With reference to the commercialization of India's space sector, consider the following statements: 1. NewSpace India Limited (NSIL) is a Public Sector Undertaking under the Department of Space, mandated to act as the nodal agency for commercializing ISRO's space products and services. 2. Unlike Antrix Corporation, NSIL primarily focuses on demand-driven procurement and manufacturing of satellites and launch vehicles through Indian industry. 3. The recent launch of a US communication satellite by ISRO was commercially facilitated by Antrix Corporation. Which of the statements given above is/are correct?

  • A.1 only
  • B.2 and 3 only
  • C.1 and 2 only
  • D.1, 2 and 3
Show Answer

Answer: C

Statement 1 is correct: NSIL was established in 2019 as a PSU under the Department of Space to be the commercial arm of ISRO, with the primary mandate of commercializing ISRO's space products and services. Statement 2 is correct: NSIL's mandate is distinct from Antrix. While Antrix focused on marketing ISRO's existing capabilities and launch services, NSIL aims to enable Indian industry to produce and supply space-related hardware and services, thereby shifting ISRO's role towards R&D and fostering a demand-driven model. Statement 3 is incorrect: As per the news, the mission was facilitated by NewSpace India Limited (NSIL), not Antrix Corporation, highlighting NSIL's growing role in international commercial launches.

3. In the context of India's growing role in the global space economy, which of the following factors has NOT been a significant contributor?

  • A.Development of cost-effective launch vehicles like PSLV and GSLV Mk-III.
  • B.Establishment of dedicated commercial entities like NewSpace India Limited (NSIL).
  • C.India's early adoption of reusable launch vehicle technology for commercial missions.
  • D.Strategic international collaborations and space diplomacy initiatives.
Show Answer

Answer: C

Option A is correct: India's PSLV is renowned globally for its reliability and cost-effectiveness, and GSLV Mk-III for launching heavier satellites, both significantly contributing to India's global appeal in launch services. Option B is correct: NSIL plays a crucial role in commercializing ISRO's services, fostering private sector participation, and securing international contracts, thereby boosting India's share in the global market. Option D is correct: Collaborations with countries like the US, France, and others, along with active space diplomacy, have expanded India's reach and partnerships, enhancing its global standing. Option C is incorrect: While ISRO is actively working on Reusable Launch Vehicle (RLV) technology (e.g., RLV-TD program), it has not yet adopted it for regular commercial missions. This technology is still in the experimental and developmental phase, and therefore, has NOT been a significant *contributor* to India's *current* growing role in the global space economy.
