सारांश
The Indian Space Research Organisation (ISRO) achieved two significant milestones by successfully launching the BlueBird Block-2 satellite into a low earth orbit (LEO) using its Launch Vehicle Mark 3 (LVM3) rocket. This mission marked the first dedicated commercial launch for a U.S. customer and deployed the largest commercial communications satellite from Indian soil.
Weighing 6,100 kg, BlueBird Block-2 is now the heaviest payload launched by LVM3. Developed by AST SpaceMobile, the satellite is designed to provide space-based broadband connectivity to smartphones, showcasing India's growing prowess in the global commercial space sector and its commitment to precision orbital injections.
पृष्ठभूमि
India's space program, spearheaded by ISRO, has a rich history of developing indigenous launch vehicles and satellites. Starting with sounding rockets and small satellite launches, ISRO gradually mastered PSLV for polar and sun-synchronous orbits and GSLV (now LVM3) for heavier payloads and geostationary transfer orbits.
The commercial arm, initially Antrix Corporation, and now primarily NewSpace India Limited (NSIL), has been instrumental in marketing ISRO's capabilities globally. The recent launch signifies a maturation of India's capabilities, moving beyond just domestic needs to cater to international commercial demands, especially for heavy communication satellites.
नवीनतम घटनाक्रम
The successful launch of BlueBird Block-2 by LVM3 marks a significant step. It's the heaviest commercial payload for LVM3 and the first dedicated commercial mission for a U.S. customer.
The satellite's purpose of providing space-based broadband connectivity to smartphones from LEO highlights the growing trend in satellite internet constellations. This achievement underscores India's increasing competitiveness in the global commercial space market, offering reliable and cost-effective launch services and precision orbital injections.
बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding India's Launch Vehicle Mark 3 (LVM3): 1. It is a three-stage launch vehicle with two solid strap-on boosters, a liquid core stage, and a cryogenic upper stage. 2. LVM3 is primarily designed to launch communication satellites into Geostationary Transfer Orbit (GTO). 3. The recent BlueBird Block-2 mission marked its first successful launch into a Low Earth Orbit (LEO) with a commercial payload. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: A
Statement 1 is correct. LVM3 (formerly GSLV Mk-III) is indeed a three-stage vehicle with two S200 solid strap-ons, an L110 liquid core stage, and a C25 cryogenic upper stage. Statement 2 is correct. LVM3's primary design objective is to launch heavy communication satellites into GTO, from where they can be maneuvered into Geostationary Orbit (GEO). Statement 3 is incorrect. While the BlueBird Block-2 mission was a significant LEO launch with a commercial payload, it was not the *first* successful launch into LEO for LVM3. LVM3 has previously launched payloads into LEO, most notably the Chandrayaan-2 orbiter and several OneWeb constellation satellites (though the OneWeb missions were also commercial, the BlueBird Block-2 is highlighted as the heaviest and for a US customer). The Chandrayaan-2 mission involved LVM3 placing the spacecraft into an Earth Parking Orbit (EPO), which is a type of LEO, before subsequent maneuvers.
2. In the context of India's commercial space sector, consider the following statements: 1. Antrix Corporation Limited is the primary commercial arm of ISRO responsible for marketing its products and services globally. 2. NewSpace India Limited (NSIL) was established to transfer matured technologies from ISRO to Indian industries and promote private sector participation. 3. The Space Activities Bill aims to provide a legal framework for private sector involvement in space activities in India. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is incorrect. While Antrix Corporation Limited was historically the primary commercial arm, NewSpace India Limited (NSIL) was established in 2019 as a Public Sector Undertaking (PSU) under the Department of Space (DoS) to be the new commercial arm of ISRO. NSIL is mandated to own and operate ISRO's operational launch vehicles and satellites, and to provide end-to-end commercial space services. Statement 2 is correct. NSIL's mandate includes manufacturing, assembly, and integration of launch vehicles and satellites through Indian industry, and promoting private sector participation in the Indian space program. Statement 3 is correct. The Space Activities Bill, though not yet enacted, aims to provide a comprehensive legal framework for regulating and promoting space activities in India, including those undertaken by private entities, ensuring safety, liability, and international obligations.
3. With reference to satellite-based broadband connectivity, which of the following statements correctly differentiates Low Earth Orbit (LEO) satellites from Geostationary Earth Orbit (GEO) satellites for this application? A) LEO satellites offer lower latency and require fewer satellites for global coverage compared to GEO satellites. B) GEO satellites are preferred for real-time communication due to their closer proximity to Earth, unlike LEO satellites. C) LEO satellites typically have a shorter lifespan and require more frequent replacement than GEO satellites. D) GEO satellites provide better coverage for polar regions, whereas LEO satellites struggle with high latitudes.
- A.LEO satellites offer lower latency and require fewer satellites for global coverage compared to GEO satellites.
- B.GEO satellites are preferred for real-time communication due to their closer proximity to Earth, unlike LEO satellites.
- C.LEO satellites typically have a shorter lifespan and require more frequent replacement than GEO satellites.
- D.GEO satellites provide better coverage for polar regions, whereas LEO satellites struggle with high latitudes.
उत्तर देखें
सही उत्तर: C
A) Incorrect. LEO satellites offer lower latency due to their closer proximity (typically 160-2000 km) compared to GEO (35,786 km), but they require a *constellation* of many satellites for continuous global coverage, whereas a single GEO satellite can cover a large fixed area. B) Incorrect. LEO satellites are preferred for real-time communication due to their lower latency. GEO satellites, despite their fixed position relative to Earth, are much farther away, leading to higher latency. C) Correct. LEO satellites operate in a more dynamic environment with atmospheric drag and higher radiation exposure (though less than MEO/GEO in some bands), leading to a generally shorter operational lifespan (5-7 years) compared to GEO satellites (10-15+ years). This necessitates more frequent launches for replacement and maintenance of LEO constellations. D) Incorrect. LEO satellites, especially those in polar orbits, are excellent for providing coverage to polar regions. GEO satellites, being positioned over the equator, have limited or no coverage at very high latitudes (near the poles).
