“This is one of the important milestones in the history of PSLV.”. Tracing the journey of PSLV, which has five variants, he said the payload capacity was initially about 860 kg and it went up to 1.9 tonne subsequently. Sivan recalled and lauded the contributions of the past and present leadership behind PSLV's successful journey in its eventful history of 26 years. Like that many missions lined up for next year," Isro chief K Sivan said. A hydrazine-fueled Vikas second stage engine ignited next, followed by a burn of the PSLV’s solid-fueled third stage, and ignition of two thrusters on the rocket’s fourth stage to inject 10 satellites into orbit. Once the satellite is in space, its radial band antenna will be unfurled to its full diameter of 11.8 feet (3.6 meters). Flying in a configuration with four strap-on solid rocket boosters, the PSLV flew southeast from Sriharikota and jettisoned its solid-fueled boosters and core stage motor in the first two minutes of the flight.

But Indian engineers have nearly doubled the PSLV’s original launch mass capacity since 1993, and the PSLV has flown in five different configurations with zero, two, four, or six strap-on boosters.

A 41-pound (19-kilogram) microsatellite developed by Hera Systems, a California-based company, also rocketed into orbit Wednesday atop India’s PSLV. In commemoration of the milestone event, a book, "PSLV-50", chronicling the various missions, the satellites and the leaders behind it was released by K Sivan. Sivan said PSLV has gone 'all over space', placing satellites in orbits, including polar and the trusted vehicle was behind Chandrayaan-1 and the Mars Orbiter Mission. Today's launch was the 50th launch of #PSLV & 75th launch from our space port in Sriharikota.Thanks for your support. Sivan said the 50 PSLV missions to date have launched more than 116,000 pounds (52.7 metric tons) of payloads into space. A third RISAT 2B-series spacecraft is scheduled for launch on a future PSLV flight in early 2020. The first variant of the PSLV launched with smaller solid rocket boosters than the strap-on motors used today. Officials confirmed the spacecraft extended its power-generation solar panels as planned shortly after launch. “PSLV has hit gold today,” said S. Somanath, director of the Vikram Sarabhai Space Center, headquarters for ISRO’s launcher development programs. The upgrades have allowed the PSLV to launch satellites into high-altitude geostationary transfer orbit. Engineers have also introduced a new capability to reignite the PSLV’s fourth stage and outfit it with solar panels for extended missions. Director, Vikram Sarabhai Space Centre, S Somanath hailed the 50th mission, saying "PSLV has hit gold today".


The 37-degree inclination orbit selected for the RISAT 2BR1 satellite does not provide global radar observation coverage, but it offers regular passes over Indian territory and neighboring Pakistan, a longtime strategic rival to India in the region.

We also have GSLV launches. ISRO officials declared the launch a success, marking the end of India’s sixth and final space launch of 2019.

India launched the first in a new generation of Cartosat 3 Earth-imaging spacecraft last month. In the next few minutes, the PSLV jettisoned a dual-payload adapter structure and ejected nine other small satellites into space. India’s 1,384-pound (628-kilogram) RISAT 2BR1 radar observation satellite was the largest payload on Wednesday’s PSLV mission. The Polar Satellite Launch Vehicle (PSLV), often hailed as a trusted workhorse, touched a new milestone of its 50th mission on Wednesday when it placed earth observation satellite RISAT-2BR1 and nine other foreign satellites in orbit, Polar Satellite Launch Vehicle (Isro) chairman K Sivan said. The other Tyvak-built nanosatellite will demonstrate space technology for NASA. At the same time, we have a large number of missions to do. Isro head Sivan, hailing the versatility and unbeatable performance of the PSLV for over the past two decades, lauded its 50th mission as "historical". About 17 percent of the mass launched by the PSLV … The satellite was developed by ISRO and carries a dish-shaped radar antenna that is folded up to fit inside the rocket’s payload compartment. “This is the 75th launch from the spaceport of India (at Sriharikota).”. The radar-equipped satellites work in concert with India’s fleet of optical reconnaissance satellites. Four more Lemur-2 CubeSats for San Francisco-based Spire Global also launched Wednesday. The PSLV has failed only twice in its history — the maiden flight of the PSLV … He also released a book commemorating the 50 launches and the scientists involved in them. ISRO originally developed the PSLV to carry Indian Earth observation satellites into low Earth orbit and end Indian reliance on foreign launchers for many missions. Wednesday’s PSLV flight occurred two weeks after India’s last PSLV mission from the spaceport at Sriharikota. The QPS-SAR 1 satellite, weighing roughly 220 pounds (100 kilograms), was built by iQPS, a Japanese company aiming to field a fleet of 36 small radar satellites to enable near-real-time observations of the Earth. Between 1994 and 2019, PSLV launched 50 Indian satellites and 222 foreign satellites for over 70 international customers from 20 countries. Live imagery beamed back to Earth from the rocket showed India’s RISAT 2BR1 radar observation satellite separating from the PSLV’s fourth stage around 16-and-a-half minutes into the mission. Sivan said the 50 PSLV missions to date have launched more than 116,000 pounds (52.7 metric tons) of payloads into space. RISAT 2BR1 follows the launch of a similar radar imaging satellite launched by India in May. The PSLV holds the record for the highest number of satellites launched on a single rocket, a mark set in 2017, when 104 spacecraft rode a PSLV into orbit. “This spacecraft is an excellent space asset, which will contribute for national security, agriculture, forestry, agriculture, disaster management, and a host of applications,” said R.V. The Isro chief said RISAT-2BR1, though a very advanced and complex satellite, was built in a short time and congratulated the team for its good work. The Earth observation network planned by iQPS is one of several commercial small satellite fleets in development in the radar-imaging sector, alongside constellations being built by the Finnish company ICEYE and U.S.-based Capella Space. "Definitely, we have had many successes. Also, there were a whole lot of others, including RV Perumal, Ramakrishnan and George Koshy, whose rich contributions propelled the PSLV to great heights, Sivan said. According to iQPS, the new spacecraft, nicknamed Izanagi, is Japan’s first small high-resolution radar satellite. I am sure team Isro as usual will rise to the occasion and make every mission a grand success," he said amid loud applause. The relative low cost and high reliability of the PSLV have made it a popular choice to launch small satellites from foreign companies and research institutions. About 17 percent of the mass launched by the PSLV missions to date have been from customer payloads. Two CubeSats manufactured by the U.S.-based CubeSat-builder Tyvak were also on the PSLV launch Wednesday. The PSLV’s guidance system aimed to inject the satellites into a 357-mile-high (576-kilometer) orbit inclined 37 degrees to the equator. The PSLV’s first mission lifted off from Sriharikota on Sept. 20, 1993, but failed to reach orbit after encountering a problem during separation of the rocket’s second and third stages. Designed for a five-year mission, RISAT 2B carries an X-band radar imaging instrument capable of resolving structures and features on Earth’s surface, regardless of daylight or weather conditions. The Polar Satellite Launch Vehicle (PSLV), often hailed as a trusted workhorse, touched a new milestone of its 50th mission on Wednesday when it placed earth observation satellite RISAT-2BR1 and nine other foreign satellites in orbit, Polar Satellite Launch Vehicle (Isro) chairman K Sivan said. India’s first orbiters to reach the moon and Mars also launched on PSLV flights. Dubbing the PSLV a "wonderful vehicle", Sivan said Dr Srinivasan conceptualised and configured it, while G Madhavan Nair made it operational.
QPS-SAR 1’s deployable synthetic aperture radar is the same 11.8-foot (3.6-meter) size of the instrument on India’s RISAT 2BR1 satellite, but the radar fits on a much smaller spacecraft. Then we also have the maiden mission of SSLV [Small Satellite Launch Vehicle] next year. "Now we are going to send a satellite to the sun's orbit", Sivan said, adding that Isro was looking at more launches next year with PSLV. pic.twitter.com/n7wDJyiGCN. "Next year we have a series of PSLV missions. Nadagouda, the RISAT 2BR1 spacecraft director. “Along with the 50th historic mission for PSLV, this mission marks another major milestone,” said K. Sivan, ISRO’s chairman. The imaging resolution of RISAT 2BR1’s radar has not been disclosed by ISRO. It has lifted 52.7 tonne to space, of which 17 per cent corresponded to customer satellites, he said. One of the CubeSats, built for an unspecified Italian company, will demonstrate search and rescue communications capabilities.

The 50th flight of an Indian Polar Satellite Launch Vehicle delivered 10 spacecraft from five nations into orbit Wednesday, including a new Indian radar surveillance platform and a batch of small commercial Earth observation satellites. Telemetry data and live video downlinked from the rocket showed the PSLV flying on course, and officials from the Indian Space Research Organization — India’s space agency — said the launcher delivered its payloads into an on-target orbit. The PSLV’s only other launch failure occurred Aug. 31, 2017, when the rocket’s payload shroud did not jettison, preventing the rocket from placing an Indian navigation satellite into orbit.
