PSLV-C45
The PSLV-C45 is the 47th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program. The Polar Satellite Launch Vehicle (PSLV)-C45 was launched on 1 April 2019 with a payload of 29 satellites, including one for electronic intelligence, along with 28 customer satellites from other countries. Details The PSLV-C45 was launched from the second launch pad of the Satish Dhawan Space Centre in Sriharikota, Andhra pradesh,India. The PSLV C45 rocket carried primary payloads like EMISAT and secondary payloads like M6P, BlueWalker 1, four Lemur-2 out of a total of thirty satellites. EMISAT is developed by DRDO. The EMISAT satellite is based on the IMS-2 bus inherited from SARAL. The nature of the payload has not been officially confirmed. It was the first flight of PSLV-QL, having 4 strap-on boosters and placed a primary payload EMISAT and a secondary payload of multiple cubesats, for example 4 Lemur-2 satellites and the M6P satellite, in sun-synchronous orbits.

List Of PSLV Launches
This is a list of launches made by Indian Space Research Organisation (ISRO) using Polar Satellite Launch Vehicle (PSLV) rockets. Notable missions PSLV flight D1 This was the first developmental flight of the PSLV-D1. The IRS-1E satellite which was proposed to be launched was derived from the engineering model of IRS-1A incorporating a similar camera and an additional German-built monocular electro-optical stereo scanner. Even though the mission was a failure, the launch team and an expert committee appointed thereafter noted that the mission had validated many technologies and that most sub-systems had performed optimally. PSLV flight C2 In the flight sequence, IRS-P4 was injected first, followed by KITSAT-3 and DLR-Tubsat in that order. The mission was supported by ISRO Telemetry, Tracking and Command Network of ground stations located at Bangalore, Sriharikota, Lucknow, Mauritius, Bearslake, Russia and Biak, Indonesia.

PSLV C-45 Captured From Launch View Gallery
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO). Some notable payloads launched by PSLV include India's first lunar probe Chandrayaan-1, India's first interplanetary mission, Mars Orbiter Mission (Mangalyaan) and India's first space observatory, Astrosat. PSLV has gained credibility as a leading provider of rideshare services for small satellites, owing to its numerous multi-satellite deployment campaigns with auxiliary payloads, usually ride-sharing along with an Indian primary payload. As of June 2022, PSLV has launched 345 foreign satellites from 36 countries. Most notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planet Labs
Planet Labs PBC (formerly Planet Labs, Inc. and Cosmogia, Inc.) is an American public Earth imaging company based in San Francisco, California. Their goal is to image the entirety of the Earth daily to monitor changes and pinpoint trends. The company designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as secondary payloads on other rocket launch missions. Each ''Dove'' is equipped with a high-powered telescope and camera programmed to capture different swaths of Earth. Each ''Dove'' Earth observation satellite continuously scans Earth, sending data once it passes over a ground station, by means of a frame image sensor. The images gathered by ''Doves'', which can be accessed online and some of which is available under an open data access policy, provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response. With acquisition of BlackBridge in July 2015, Planet La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satish Dhawan Space Centre Second Launch Pad
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 launches ...

Spacecraft Launched By India In 2019
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success. Hypothetical in-space propulsion technologies describe the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
