GSLV Mk III in Race with Spacex's Falcon 9 for Global Satellite Market GSLV Mk III in Race with SpaceX’s Falcon 9 for Global Satellite Market NSIL will offer India’s heaviest rocket to global customers to launch their satellites from Indian soil [email protected] Bengaluru: State-owned NewSpace India Ltd will offer India’s heaviest rocket — Geosynchronous Satellite Launch Vehicle — GSLV Mk III against SpaceX’s Falcon 9 as it taps global customers to launch their communication satellites from Indian soil. The homegrown rocket developed by the Indian Space Research Organisation (Isro) can launch 4-tonne communication satellites to a geostationary transit orbit (GTO), or 36,000 kilometres into space, and around 10 tonnes of payload to lowearth orbit. Falcon9 of SpaceX, which reuses boosters to bring down launch costs, can put payloads of up to 8.3 tonnes in GTO and 22 tonnes to low-earth orbit. “There are many customers who are keen to launch their communication satellites as a dedicated payload instead of (as) a co-passenger,” said D Radhakrishnan, director — Technical & Strategy, NSIL. Most communication satellites weigh around 4-5 tonnes and Falcon9, due to its larger capacity, can carry two satellites. The co-passenger may have to wait for the main satellite to be ready for launch, he said. GSLV Mk III will be competitive in launching 4-tonne class of satellites despite competition from SpaceX and Soyuz, the Russian rocket offered by Arianespace, Radhakrishnan said. After India opened up its space sector last year, NSIL has been in talks with Isro to take over its proven rockets as well as operating satellites under its fold. Isro will focus on research, future technologies and deep space missions. Radhakrishnan said NSIL was also in talks with firms such as OneWeb — which is building a mega constellation of broadband satellites — to offer GSLV Mk III to launch the fleet. “They need to send hundreds of satellites for their constellation, and it has to be replaced every five years,” said Radhakrishnan. GSLV Mk III, which has done four launches including India’s second mission to the moon Chandrayaan-2 since its first fight in 2014, will be the vehicle for India’s humanspace flight Gaganyaan planned by 2023. Two unmanned missions would be flown prior to sending Indian astronauts to space on the rocket. Following the successful launch of Brazil’s Amazonia satellite on Isro’s workhorse Polar Satellite Launch Vehicle (PSLV), which was the first dedicated launch customer for NSIL, it has secured orders to launch four dedicated satellites. One of them would be on the planned small satellite launch vehicle (SSLV), which will make its first flight this year. It has also floated a request for proposal (RFP) to five Indian firms to build the PSLV and expects to close the vendor in five months. The initial order would be for five PSLV rockets. NSIL is also looking at opportunities from global customers to build and launch satellites from Indian soil as well as operate them on behalf of clients. Several Indian startups such as Skyroot Aerospace, Agnikul Cosmos, Bellatrix and Ahmedabadbased Omspace Rocket are building small rockets to launch small and medium sized satellites into lowearth orbit. .

The refined kerosene needs lesser space to make it possible to carry more propellant in the semi cryogenic fuel part. Semi cryogenics is more powerful, ecofriendly and the cost effective compared to cryogenic engines. Key Words: Semi cryogenics, Cryogenics, Propellant, ULV. 1. INTRODUCTION: Kerosene as a fuel has its advantage of burn off gas eco-friendly and cost effective and relative safety. Unlike liquid hydrogen and oxygen which has to store at -253 and 183 degree Celsius respectively, it is stable at room temperature. Kerosene is a fuel which produces line fumes in its paraffin form, it is considered environmentally friendly. It is a non-corrosive fuel, safe to store for a long time. Depending in what kind of container in which it is stored, kerosene can be kept in storage for a 1 year to 10 year.

Yet very little is known about this story, and about the politics and perceptions that are continuing to drive Japanese efforts despite many outright failures in the indigenization of the industry. This story, therefore, is important not just because of the widespread economic and technological merits of the space launch vehicles sector which are considerable. It is also important because it speaks directly to the ongoing debates about the Japanese developmental state and, contrary to the new wisdom in light of Japan's recession, the continuation of its high technology policy as a whole.

  • Indian Remote Sensing Satellites (IRS)
    Topic: Indian Remote Sensing Satellites (IRS) Course: Remote Sensing and GIS (CC-11) M.A. Geography (Sem.-3) By Dr. Md. Nazim Professor, Department of Geography Patna College, Patna University Lecture-5 Concept: India's remote sensing program was developed with the idea of applying space technologies for the benefit of human kind and the development of the country. The program involved the development of three principal capabilities. The first was to design, build and launch satellites to a sun synchronous orbit. The second was to establish and operate ground stations for spacecraft control, data transfer along with data processing and archival. The third was to use the data obtained for various applications on the ground. India demonstrated the ability of remote sensing for societal application by detecting coconut root-wilt disease from a helicopter mounted multispectral camera in 1970. This was followed by flying two experimental satellites, Bhaskara-1 in 1979 and Bhaskara-2 in 1981. These satellites carried optical and microwave payloads. India's remote sensing programme under the Indian Space Research Organization (ISRO) started off in 1988 with the IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, which was successfully launched into a polar sun-synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur. It has sensors like LISS-I which had a spatial resolution of 72.5 meters with a swath of 148 km on ground. LISS-II had two separate imaging sensors, LISS-II A and LISS-II B, with spatial resolution of 36.25 meters each and mounted on the spacecraft in such a way to provide a composite swath of 146.98 km on ground.

Strengthening the C4ISR Capabilities of India’s Armed Forces: The Role of Small Satellites ABSTRACT Small satellites have gained considerable importance in recent years. Although small spacecraft have existed for decades, their military applications have recently gained prominence owing to technological advances in their development and integration into the armed services of the major spacefaring countries across the world. This paper analyses the significance of small satellites in the C4ISR capabilities of the three service branches of the Indian military. Small satellites are not a panacea for the C4ISR needs of the Indian Army, Navy and Air Force, but will help partially address their sensor-related requirements. They also contribute to a multi-layered and distributed capability for the Indian armed services. Investment in Small Satellites should assume greater salience in Indian defence planning in the coming years.

  • Small Launchers in a Pandemic World - 2021 Edition of the Annual Industry Survey
    SSC21- IV-07 Small Launchers in a Pandemic World - 2021 Edition of the Annual Industry Survey Carlos Niederstrasser Northrop Grumman Corporation 45101 Warp Drive, Dulles, VA 20166 USA; +1.703.406.5504 [email protected] ABSTRACT Even with the challenges posed by the world-wide COVID pandemic, small vehicle "Launch Fever" has not abated. In 2015 we first presented this survey at the AIAA/USU Conference on Small Satellites1, and we identified twenty small launch vehicles under development. By mid-2021 ten vehicles in this class were operational, 48 were identified under development, and a staggering 43 more were potential new entrants. Some are spurred by renewed government investment in space, such as what we see in the U.K. Others are new commercial entries from unexpected markets such as China. All are inspired by the success of SpaceX and the desire to capitalize on the perceived demand caused by the mega constellations. In this paper we present an overview of the small launch vehicles under development today. When available, we compare their capabilities, stated mission goals, cost and funding sources, and their publicized testing progress. We also review the growing number of entrants that have dropped out since we first started this report. Despite the COVID-19 pandemic, one system became operational in the past 12 months and two or three more systems hope to achieve their first successful launch in 2021. There is evidence that this could be the year when the small launch market finally becomes saturated; however, expectations continue to be high and many new entrants hope that there is room for more providers.
