GSAT Template Edit
Bro
from where you know these Planned launches especially GSAT-UHF, etc. Abdullah1099 (talk) 08:47, 14 October 2025 (UTC)
- Hello, @Abdullah1099, for all the rest check out GSAT page. I am not sure who added GSAT-UHF, it was already there when I editted. I was myself confused about it. Feel free to remove it and any other GSAT missions you think to be irrelevant.
- Have a good day. Manav2311 (talk) 08:51, 14 October 2025 (UTC)
- Also GSAT-6A was lost in April 2018. Thus, I added it to Past missions. I am not sure about the ALL the Active missions too. We have to check all of them and update the template and their pages respectively. Please help me in doing so yourself if you have time. I am a little busy till November now. Bye Manav2311 (talk) 08:55, 14 October 2025 (UTC)
- Bro i mean does any of the upcoming ones have any references Abdullah1099 (talk) 10:59, 14 October 2025 (UTC)
- K Sivan, secretary, DoS, said: “...We are already in advanced talks for GSAT-22 which will be for another major DTH provider. Aside from this, customers have been identified for GSAT-20, 23 and 32 but we cannot reveal the names at this juncture as the talks are still at the initial stages.” Space PSU NSIL to launch 4 more demand-driven communication satellites - Times of India Manav2311 (talk) 13:41, 18 October 2025 (UTC)
- Bro, I know they already told they are working on GSAT-20, 22, 23 and 32 but from where you got the other ones, that i want to know. Abdullah1099 (talk) 14:55, 18 October 2025 (UTC)
- Although IDK why NSIL website doesn't have specific GSAT satellite by names in its tenders pages. What I mean to say is that they don't openly say in tenders that so and so GSAT tender is won by so and so company/corp/gov. agency. Also, this reference only confirms like 3 of them, rest of them I think are still with ISRO so probably U R Rao Satellite Centre will build in like the next 3-4 years, and we'll get the confirmation then. Manav2311 (talk) 13:46, 18 October 2025 (UTC)
- Found something interesting going on for GSAT-32. DRDO has an ongoing tender for "Development And Testing Of Satellite Terminals For Gsat 32/N3". So that confirms that we'll be seeing more on this within the next 3 months or so before actual launch date is announced by Feb 2026 (totally my viewpoint) Manav2311 (talk) 14:02, 18 October 2025 (UTC)
- Other than those four planned satellite and some GSAT-7 series satellites i can't find any other planned satellite. Of course they could be working on them but they don't put it on public. So other ones should not be put. Abdullah1099 (talk) 14:57, 18 October 2025 (UTC)
- I absolutely agree that the others, specifically GSAT 21 and GSAT 25 to 28 should be removed even from GSAT page too. But I think this is a matter of continuity here. See until GSAT 19, all launches were numbered accordingly, and no number was missing (and if it was missing ISRO filled it by 2018 [eg. GSAT-11]). After that NSIL was incorporated in March 2019, so ISRO left GSAT 20 to 28 for NSIL thus the GSAT N series was started. Then GSAT 29 to 31 were launched between November 2018 and January 2020. So, as you can clearly see either NSIL/ISRO would have to now launch GSAT 21 and GSAT 25-28 to cover the gaps and I think they absolutely would because they did so before too. It's just that because of all these replacement satellites like 12R and 7R, other ones are getting delayed. However, if you think that 21,25-28 should be removed feel free to do so, I agree completely with you that no public info. on these has been released till date. [P.S. What is GSAT-UHF ?? We have to remove that too from GSAT page.] Manav2311 (talk) 10:25, 25 October 2025 (UTC)
- Ok, I am glad you understood what i want to tell. Abdullah1099 (talk) 11:55, 25 October 2025 (UTC)

Project POSTAR was the first space experiment created entirely by members of the Boy Scouts of America. On September 12, 1992, Space Shuttle Endeavour mission STS-47 carried 10 Get Away Special (GAS) canisters. Amongst these GAS cansisters was G-102 sponsored by the Boy Scouts of America's Exploring Division in cooperation with the TRW Systems Integration Group, Fairfax, Virginia. The project was named Project POSTAR. (The name was a combination of the words "Post" and "Star"). |

Space Shuttle Enterprise
The Space Shuttle Enterprise (OV-101) was the first orbiter built in the Space Shuttle program. Designed for atmospheric test flights, it lacked both engines and a heat shield, making it unable to go to space. Rolled out on 17 September 1976, it was initially named Constitution, but was renamed following a large letter-writing campaign from Trekkies. Unlike its eponym, the USS Enterprise from the original Star Trek series, OV-101 never achieved spaceflight; originally intended to be refitted to become the second space-rated orbiter after Columbia, changes to the design of the Space Shuttle made it both simpler and cheaper to instead construct a new shuttle, Challenger, around a test article. It was later considered for refitting following the Challenger disaster, but it was instead decided to build a replacement, Endeavour, out of spare parts from the construction of Discovery and Atlantis. Enterprise flew a total of five times, from 12 August to 26 October, 1977. It was then flown to Marshall Space Flight Center in Alabama, where it was placed into the Saturn V dynamic test stand for the Mated Vertical Ground Vibration Testing, in order to test the Space Shuttle's launch stack. It was then used for a variety of fit checks at Kennedy Space Center and Vandenberg Air Force Base, between which it toured Europe and North America, including a showing at the 1984 Louisiana World Exposition. It was then moved to the Smithsonian Institution's National Air and Space Museum on 18 November 1985. It was then moved to its present location aboard the USS Intrepid museum ship on 12 December 2011. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Zond 6 was a formal member of the Soviet Zond program, and an unpiloted version of the Soyuz 7K-L1 crewed Moon-flyby spacecraft. It was launched on a lunar flyby mission on November 10, 1968, from a parent satellite (68-101B) in Earth parking orbit. The spacecraft carried a biological payload of turtles, flies, and bacteria. It also carried scientific probes including cosmic ray, micrometeoroid detectors, and photographic equipment. The mission was a precursor to a crewed circumlunar flight which the Soviets hoped could occur in December 1968, thus beating the American Apollo 8. However, after rounding the Moon on November 14, Zond 6 crashed on its return to Earth, due to a parachute failure when the parachute was detached from the capsule too early. |

Explosion on the Cygnus CRS Orb-3
On 28 October, 2014, Cygnus Orb-3 was launched at 22:22:38 UTC. 15 seconds after liftoff, one of the launch vehicle's AJ26 (modified NK-33s) ruptured, resulting in the craft falling. The mission was scrubbed eight seconds later at 22:23:01 UTC. The subsequent investigation found that the liquid oxygen turbopump exploded, severing nearby propellant lines. This resulted in a fire that damaged various engine components. The cause of the LOX turbopump's failure remains unknown. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Exoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) is a proposed space telescope for NASA's Explorer program to observe circumstellar protoplanetary and debris discs and study planet formation around nearby (within 100 parsecs) stars of spectral classes M to B. Had it been selected for development, it was proposed to launch in 2019. The spacecraft concept proposed to use a 70 centimeter diameter telescope-mounted coronagraph called PIAA (Phase Induced Amplitude Apodized Coronagraph) to suppress starlight in order to be able to detect fainter radiation of circumstellar dust. Characterizing constitution of such disks would provide clues for planetary formation (mostly in habitable zones), while already existing exoplanets can be detected through their interaction with dust disk. The project's Principal Investigator is Glenn Schneider. |

Wernher von Braun with the Rocketdyne F-1 engines
Pictured here are two titans of spaceflight history: Dr. Wernher von Braun, one of the main figures of the early American space program and designer of both the Saturn V and V-2 rockets, and five (four visible) Rocketdyne F-1 engines, used on the Saturn V Dynamic Test Vehicle. Dr. von Braun's career is noted for a great number of achievements in human spaceflight, including the Apollo mission which successfully put human beings on the moon; nevertheless, it is burdened with the shadow of his activities in the Nazi Party, especially concerning his work on the V-2. The engines behind him, in addition to being immense, have the honor of being the only engines used to get humans to the moon, as of the time of writing. Developed in the late 1950s, the 8,400 kilograms (18,500 lb) engines are still the most powerful single combustion chamber liquid-propellant rocket ever made. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

A parking orbit is a temporary orbit used during the launch of a spacecraft. A launch vehicle follows a trajectory to the parking orbit, then coasts for a while, then engines fire again to enter the final desired trajectory. An alternative trajectory that is used on some missions is direct injection, where the rocket fires continuously (except during staging) until its fuel is exhausted, ending with the payload on the final trajectory. This technique was first used by the Soviet Venera 1 mission to Venus in 1961. |

OTV-2 (also known as USA-226) was the first flight of the second Boeing X-37B, an American unmanned robotic vertical-takeoff, horizontal-landing spaceplane. It was launched aboard an Atlas V rocket from Cape Canaveral on 5 March 2011, and landed at Vandenberg Air Force Base on 16 June 2012. It operated in low Earth orbit. Its USA-226 mission designation is part of the USA series. The spaceplane was operated by Air Force Space Command, which has not revealed the specific identity of the payload for the first flight. The Air Force stated only that the spacecraft would "demonstrate various experiments and allow satellite sensors, subsystems, components, and associated technology to be transported into space and back." |

STS-1
STS-1 (Space Transportation System-1) was the first orbital spaceflight of NASA's Space Shuttle program. The first orbiter, Columbia, launched on April 12, 1981, and returned on April 14, 1981, 54.5 hours later, having orbited the Earth 37 times. Columbia carried a crew of two—commander John W. Young and pilot Robert L. Crippen. It was the first American crewed space flight since the Apollo–Soyuz Test Project (ASTP) in 1975. STS-1 was also the maiden test flight of a new American spacecraft to carry a crew, though it was preceded by atmospheric testing (ALT) of the orbiter and ground testing of the Space Shuttle system. The launch occurred on the 20th anniversary of Vostok 1, the first human spaceflight, performed by Yuri Gagarin for the USSR. This was a coincidence rather than a celebration of the anniversary; a technical problem had prevented STS-1 from launching two days earlier, as was planned. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The Gallaudet Eleven were a group of eleven deaf men recruited in the late 1950s and 1960s to participate in a joint research program led by NASA and the U.S. Naval School of Aviation Medicine (later changed to Aerospace Medical Association) to study the effects of prolonged weightlessness on the human body. They were selected for participation in the study because damage they had sustained to the vestibular systems of their inner ears had granted them immunity to motion sickness, making them uniquely resilient to certain physical studies that would have made other test subjects nauseous. |

Clayton Anderson under weightlessness
A demonstration of weightlessness by astronaut Clayton Anderson, particularly its effect on liquids. The water's surface tension keeps it in a sphere, which here results in the light reflecting off of Anderson being refracted in such a way that it appears upside-down. It is only upside-down relative to Anderson, as there is no "up" or "down" in a weightless environment beyond convention. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
