PSLV-C40
PSLV-C40 was the 42nd mission of the Indian Polar Satellite Launch Vehicle (PSLV) program in the XL configuration. PSLV-C40 successfully carried and deployed 31 satellites in sun-synchronous orbits. Overview Two Surrey Satellite Technology satellites were launched, the 100 kg Carbonite-2 Earth Observation technology demonstrator and the 168 kg Telesat LEO Phase 1 communications satellite. Four SpaceBEE sub-CubeSats were launched to test "2-way satellite communications and data relay", probably for the Silicon Valley company Swarm Technologies. However the U.S. Federal Communications Commission (FCC) had denied regulatory approval for Swarm Technologies 10 cm × 10 cm × 2.8 cm BEE satellites as they were too small to be reliably tracked by the United States Space Surveillance Network, so may become an impact hazard to other satellites. If confirmed the FCC may take regulatory action over these satellites. Launched satellites * Astranis DemoSat-2 * Car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cartosat-2F
Cartosat-2F is the eighth satellite in the Cartosat-2 Series. It is an Earth observation satellite launched on the PSLV-C40 mission by the Indian Space Research Organisation (ISRO). History Originally, Cartosat-2E was published as the last Cartosat-2 satellite to be launched, as Cartosat-3 Series spacecraft were scheduled to launch in 2018. Cartosat-2F was first listed on launch schedules as Cartosat-2ER, a name possibly indicating it was originally a replica of Cartosat-2E to be used as a spare. Satellite description Like other satellites in the series, Cartosat-2F was built on an IRS-2 bus. It uses reaction wheels, magnetorquers, and hydrazine-fueled reaction control thrusters for stability. It has a design service life of five years. Cartosat-2F has three main remote sensing instruments, a panchromatic camera called PAN, a four channel visible/near infrared radiometer called HRMX, and a Event Monitoring camera (EvM). * Panchromatic camera (PAN) is capable of taking p ...

PicSat
PicSat is a French observatory nanosatellite, designed to measure the transit of Beta Pictoris b, an exoplanet which orbits the star Beta Pictoris. PicSat was designed and built by a team of scientists led by Dr. Sylvestre Lacour, astrophysicist and instrumentalist at the High Angular Resolution in Astrophysics group in the LESIA laboratory with Paris Observatory, Paris Sciences et Lettres University and the French National Centre for Scientific Research (CNRS). It was launched on January 12, 2018, and operated for more than 10 weeks before falling silent on 20 March 2018. Background Beta Pictoris system With an age of about 23 million years, Beta Pictoris is a very young star. Compared to the Sun, which is 4.5 billion years old, Beta Pictoris is about twice as large in mass and size. Beta Pictoris is relatively close to the Sun: just 63.4 light-years away, making it bright and easy to observe. This makes Beta Pictoris interesting for study as it allows astronomers to lea ...

PSLV-C39
Polar Satellite Launch Vehicle – C39 was the forty-first flight of the PSLV series of launch vehicles on 31 August 2017. Launched in its XL configuration, the vehicle suffered a rare failure – the first failure after 24 years of operations when the heat shield In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is al ... failed to separate and the payload became trapped inside the heat shield and could not be deployed. The mission PSLV-C39 was supposed to launch the IRNSS-1H, the eighth satellite of the Indian Regional Navigation Satellite System (IRNSS). The launch was necessitated due to the failure of all the Cesium atomic clocks in one of the satellites of the constellation which rendered the navigation system non-operational. The rocket successfully lifted off from the launch pad an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbonite-2
The Defence Intelligence Fusion Centre (DIFC) is based at RAF Wyton in Cambridgeshire. Largely created from the staff of the National Imagery Exploitation Centre (formerly known as the Joint Air Reconnaissance Intelligence Centre (JARIC)) and then known for several years as the Defence Geospatial Intelligence Fusion Centre, it can trace its history back to clandestine reconnaissance operations at the beginning of the Second World War by Sydney Cotton on behalf of MI6 and then MI4, and the formation of the Allied Central Interpretation Unit at RAF Medmenham (sister to Bletchley Park). Today, DIFC's role has grown beyond just imagery intelligence. Part of the Joint Forces Intelligence Group (JFIG) within Defence Intelligence, DIFC's primary role is to support Defence planning, current operations and the intelligence assessment process. DIFC still provides specialist imagery intelligence, but also conducts multi-disciplinary intelligence fusion for the armed forces and other UK G ...

PSLV
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 notab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
