सारांश
India's heaviest launch vehicle, LVM-3 (Launch Vehicle Mark-3), successfully placed the US communication satellite Bluebird Block-2, weighing approximately 6,100 kg, into a precise orbit. This marks LVM-3's ninth consecutive successful launch and its third commercial mission, demonstrating 100% reliability.
The mission is significant as it represents the heaviest satellite ever launched by an Indian rocket, showcasing ISRO's enhanced heavy-lift capability. This achievement strengthens India's growing role in the global commercial launch market, especially through its commercial arm NSIL (NewSpace India Limited), and builds confidence for future human spaceflight missions like Gaganyaan.
पृष्ठभूमि
India's space program, spearheaded by ISRO, has evolved significantly since its inception. From early sounding rockets and experimental satellites, it has matured to develop indigenous launch vehicles like PSLV and GSLV.
The GSLV Mk-III, now renamed LVM-3, was conceptualized to launch heavier communication satellites into Geostationary Transfer Orbit (GTO) and has been instrumental in demonstrating India's heavy-lift capabilities. The commercial arm, Antrix Corporation, was established earlier, followed by NewSpace India Limited (NSIL) in 2019, to further boost India's participation in the global commercial space market.
नवीनतम घटनाक्रम
The recent successful launch of the US communication satellite Bluebird Block-2 by LVM-3 marks a significant milestone. It is LVM-3's ninth consecutive successful mission and its third commercial launch, demonstrating 100% reliability.
This mission is particularly noteworthy as it involved the heaviest satellite (6,100 kg) ever launched by an Indian rocket, showcasing ISRO's enhanced heavy-lift capability. This achievement solidifies India's position in the global commercial launch market, driven by NSIL, and provides critical validation for future human spaceflight missions like Gaganyaan.
बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding India's Launch Vehicle Mark-3 (LVM-3): 1. It is a three-stage launch vehicle with two solid strap-on boosters, a liquid core stage, and a cryogenic upper stage. 2. LVM-3 is primarily designed to launch satellites into Low Earth Orbit (LEO) for Earth observation missions. 3. Its successful missions have been crucial in validating technologies for India's Gaganyaan human spaceflight program. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. LVM-3 (formerly GSLV Mk-III) is indeed a three-stage vehicle with two S200 solid strap-on boosters, an L110 liquid core stage, and a C25 cryogenic upper stage. Statement 2 is incorrect. While LVM-3 can launch into LEO, its primary design objective and strength lie in launching heavier communication satellites into Geostationary Transfer Orbit (GTO) and subsequently into Geostationary Orbit (GEO). It has a LEO capability of 8,000 kg and a GTO capability of 4,000 kg. Statement 3 is correct. LVM-3 has been identified as the launch vehicle for the Gaganyaan mission, and its reliability and heavy-lift capability demonstrated through various missions are crucial for the human spaceflight program.
2. In the context of India's commercial space sector, consider the following statements about NewSpace India Limited (NSIL): 1. NSIL is a Public Sector Undertaking (PSU) under the Department of Space, primarily responsible for manufacturing launch vehicles and satellites. 2. It acts as the commercial arm of ISRO, offering end-to-end launch services and satellite solutions to global customers. 3. Unlike Antrix Corporation, NSIL's mandate includes facilitating the transfer of technologies developed by ISRO to Indian industries. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is incorrect. While NSIL is a PSU under the Department of Space, its primary role is not manufacturing launch vehicles and satellites itself. Instead, it aims to enable Indian industries to manufacture them. ISRO continues to be involved in R&D and initial manufacturing, but NSIL's role is to scale up commercial production through industry participation. Statement 2 is correct. NSIL is indeed the commercial arm of ISRO, mandated to provide end-to-end launch services, satellite building, and related solutions to both domestic and international customers. Statement 3 is correct. A key distinction of NSIL from Antrix Corporation is its focus on promoting Indian industry participation in space activities, including the transfer of ISRO-developed technologies to private players for commercial production and services. Antrix was primarily a marketing arm for ISRO's products and services.
3. With reference to the types of orbits used for satellites, which of the following statements is/are correct? 1. Geostationary Earth Orbit (GEO) satellites appear stationary from the Earth's surface and are primarily used for communication and meteorological purposes. 2. Low Earth Orbit (LEO) satellites are typically used for high-resolution imaging and internet constellations due to their proximity to Earth. 3. A satellite launched into a Geostationary Transfer Orbit (GTO) requires further propulsion to reach its final Geostationary Earth Orbit (GEO). Select the correct answer using the code given below:
- A.1 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: D
Statement 1 is correct. GEO satellites orbit at an altitude of approximately 35,786 km above the Earth's equator, with an orbital period matching the Earth's rotation. This makes them appear stationary from the ground, ideal for continuous communication and weather monitoring. Statement 2 is correct. LEO satellites orbit at altitudes typically between 160 km and 2,000 km. Their close proximity allows for higher resolution imaging (e.g., spy satellites, Earth observation) and reduced signal latency, making them suitable for satellite internet constellations (e.g., Starlink, OneWeb). Statement 3 is correct. GTO is an elliptical orbit used as an intermediate step to reach GEO. A launch vehicle typically places a satellite into GTO, and then the satellite's own propulsion system (apogee motor) fires at the apogee (highest point) of the GTO to circularize the orbit and raise it to the final GEO.
