Human spaceflight is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. People trained for spaceflight are called astronauts, cosmonauts (Russian), or taikonauts (Chinese); and non-professionals are referred to as spaceflight participants or spacefarers.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies had launched humans on a suborbital trajectory. The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale defines spaceflight as any flight over 100 kilometers (62 mi). In the United States professional, military, and commercial astronauts who travel above an altitude of 80 kilometers (50 mi) are awarded the United States Astronaut Badge. This article follows the FAI definition of spaceflight.
The Indian Space Research Organisation is the national space agency of India, headquartered in Bangalore. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well. ISRO is India's primary agency for performing tasks related to space-based applications, space exploration and the development of related technologies. It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites.
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 three types:
The Launch Vehicle Mark-3, previously referred as the Geosynchronous Satellite Launch Vehicle Mark III, is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM 3 has a higher payload capacity than its predecessor, GSLV Mk II.
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 2023 on an LVM 3 rocket.
Gaganyaan 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 LVM3 in December 2021, but this has since been delayed due to lockdown to no earlier than 2024.
The Boeing CST-100Starliner is a class of two partially reusable spacecraft designed to transport crew to the International Space Station (ISS) and other low-Earth-orbit destinations. It is manufactured by Boeing for its participation in NASA's Commercial Crew Program (CCP). The spacecraft consists of a reusable crew capsule and an expendable service module.
The Chandrayaan programme, also known as the Indian Lunar Exploration Programme is an ongoing series of outer space missions by the Indian Space Research Organisation (ISRO). The programme incorporates lunar orbiter, impactor, soft lander and rover spacecraft. The name of the programme is from Sanskrit candrayāna (transl. 'Moon-craft').
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.
This article documents expected notable spaceflight events during the 2020s.
This article documents notable spaceflight events during the year 2022. For the second year in a row, new records were set for the most orbital launch attempts and the most successful orbital launches in a year.
The Human Space Flight Centre (HSFC) is a body under the Indian Space Research Organisation (ISRO) to coordinate the Indian Human Spaceflight Programme. The agency will be responsible for implementation of the Gaganyaan project. The first crewed flight is planned for 2024 on a home-grown GSLV-III rocket.
Indian Data Relay Satellite System or IDRSS is a planned Indian constellation of Inter-satellite communications satellites. It is planned to initially comprise two satellites, CMS-04 & IDRSS-2 in geostationary orbit. It will facilitate relay of information between various Indian spacecraft, in-flight launch vehicle monitoring and assist Indian Human Spaceflight Programme.
Vyommitra is a female-looking spacefaring humanoid robot being developed by the Indian Space Research Organisation to function on-board the Gaganyaan, a crewed orbital spacecraft. Vyommitra was first unveiled on 22 January 2020 at the Human Spaceflight and Exploration symposium in Bengaluru.
TV-D1 will be a high altitude abort test as part of the Gaganyaan program, set to be held in May 2023.
The ISRO Space Station (ISS) is a planned space station to be constructed by India and operated by Indian Space Research Organisation. The space station would weigh 20 tonnes and maintain an orbit of approximately 400 kilometres above the Earth, where astronauts could stay for 15-20 days. Originally planned to be launched in 2030, it was further postponed to 2035 due to delays led by technical issues related with the Gaganyaan crewed spaceflight mission and the COVID-19 pandemic.
