ISRO Pad Abort Test
ISRO Pad Abort Test was an Indian Space Research Organisation launch escape system test of its crew module as part of Indian Human Spaceflight Programme. The successful test took place on 5 July 2018. A Pad Abort Test is a trial run for the spacecraft's launch abort system (sometimes called a launch escape system). This system is designed to quickly get the crew and spacecraft away from the rocket in the event of a potential failure. It is similar to an ejection seat for a fighter pilot, but instead of ejecting the pilot out of the spacecraft, the entire spacecraft is "ejected" away from the launch vehicle. The technology developed is expected to be applied to the first Indian crewed spacecraft called ''Gaganyaan'', scheduled to be launched in 2022. Flight The countdown for the test started at 2:00 am (IST) on 5 July 2018. At 7:00 am (IST) The Crew Escape System with crew module successfully lifted-off from Satish Dhawan Space Centre. The crew module was accelerated to 10 g a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Escape System
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule that can be used to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is still on the launch pad, or during its ascent. Such systems are usually of two types: *A solid-fueled rocket, mounted above the capsule on a tower, which delivers a relatively large thrust for a brief period of time to send the capsule a safe distance away from the launch vehicle, at which point the capsule's parachute recovery system can be used for a safe landing on ground or water. The tower and rocket are jettisoned from the space vehicle in a normal flight at the point where it is either no longer needed, or cannot be e ...

The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, on the urging of scientist Vikram Sarabhai, recognising the need in space research. INCOSPAR grew and became ISRO in 1969, within DAE. In 1972, the government of India set up a Space Commission and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaganyaan
Gaganyaan (Sanskrit IAST: ''gagan-yāna'', ) is an Indian crewed orbital spacecraft intended to be the formative spacecraft of the Indian Human Spaceflight Programme. The spacecraft is being designed to carry three people, and a planned upgraded version will be equipped with rendezvous and docking capability. In its maiden crewed mission, Indian Space Research Organisation (ISRO)'s largely autonomous 5.3 metric tonnes capsule will orbit the Earth at 400 km altitude for up to seven days with a two or three-person crew on board. The first crewed mission was originally planned to be launched on ISRO's LVM 3 in December 2021, but this has since been delayed to no earlier than 2024. This Hindustan Aeronautics Limited (HAL) manufactured crew module had its first un-crewed experimental flight on 18 December 2014. , design of the crew module has been completed. Defence Research and Development Organisation (DRDO) will provide support for critical human-centric systems and technolo ...

Boilerplate (spaceflight)
A boilerplate spacecraft, also known as a mass simulator, is a nonfunctional craft or payload that is used to test various configurations and basic size, load, and handling characteristics of rocket launch vehicles. It is far less expensive to build multiple, full-scale, non-functional boilerplate spacecraft than it is to develop the full system (design, test, redesign, and launch). In this way, boilerplate spacecraft allow components and aspects of cutting-edge aerospace projects to be tested while detailed contracts for the final project are being negotiated. These tests may be used to develop procedures for mating a spacecraft to its launch vehicle, emergency access and egress, maintenance support activities, and various transportation processes. Boilerplate spacecraft are most commonly used to test crewed spacecraft; for example, in the early 1960s, NASA performed many tests using boilerplate Apollo spacecraft atop Saturn I rockets, and Mercury spacecraft atop Atlas roc ...

Satish Dhawan Space Centre
Satish Dhawan Space Centre - SDSC (formerly Sriharikota Range - SHAR) is a rocket launch centre ( spaceport) operated by Indian Space Research Organisation (ISRO). It is located in Sriharikota, Tirupati district of Andhra Pradesh. Sriharikota Range was renamed in 2002 after ISRO's former chairman Satish Dhawan. History Sriharikota island was chosen in 1969 for a satellite launching station. The centre became operational in 1971 when an RH-125 sounding rocket was launched. The first attempted launch of an orbital satellite, Rohini 1A aboard a Satellite Launch Vehicle, took place on 10 August 1979, but due to a failure in thrust vectoring of the rocket's second stage, the satellite's orbit decayed on 19 August 1979. SHAR was named as 'Satish Dhawan Space Centre SHAR' (SDSC), on 5 September 2002, in memory of Satish Dhawan, former chairman of the ISRO. The SHAR facility now consists of two launch pads, with the second built in 2005. The second launch pad was used for launc ...

Indian Human Spaceflight Programme
The Indian Human Spaceflight Programme (IHSP) was initiated in 2007 by the Indian Space Research Organisation (ISRO) to develop the technology needed to launch crewed orbital spacecraft into low Earth orbit. The first uncrewed flight, named Gaganyaan 1, is scheduled to launch no earlier than mid 2024 on an LVM 3 rocket. Before the ''Gaganyaan'' mission announcement in August 2018, human spaceflight was not a priority for ISRO, but it had been working on related technologies and it performed a Crew Module Atmospheric Re-entry Experiment and a Pad Abort Test for the mission. In December 2018, the government approved further 100 billion ( US$1.5 billion) for a 7-days crewed flight of 2–3 astronauts.Indians T ...

TV-D1
Test Vehicle Abort Mission-1 (TV-D1) was a high altitude abort test performed as part of the Gaganyaan program, initially set to be held on 21 October 2023 at around 02:30 UTC (08:00 IST). Liftoff was delayed to 03:15 UTC due to weather issues, and five seconds before launch it was put on hold by the on-board computer due to an engine anomaly, as reported in ISRO's mission livestream. The launch occurred at 04:30 UTC, and the crew module successfully separated from the launch vehicle. The crew module was successfully recovered by the Indian Navy. India is the fourth country, after Russia, the United States, and China, to successfully test this technology. Background In April 2022, it was proposed that both demonstration missions should have a depressurized crew module. On 10 August 2022 ISRO performed a successful static test of the Crew Escape System (CES). The crew module fairing and the high altitude abort engine were delivered by Hindustan Aeronautics Limited on 18 August 2022 ...

''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pro ...

G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
