At 5:59 a.m. Monday, the Indian Space Research Organisation (ISRO) launched its earth observation satellite EOS-4, as well as two co-passenger technology demonstrations and scientific spacecraft, from the country’s sole spaceport in Sriharikota, Andhra Pradesh.

The launch director stated that all three satellites had been safely deployed to applause in Mission Control. “The objective of PSLV-C52 has been effectively completed,” Isro chairman S Somnath stated after the launch.

“Three satellites, EOS-04, INSPIREsat-1, and INST-2TD, were successfully injected into a sun-synchronous polar orbit of 529 km after a journey of around 17 minutes 34 seconds.” The satellites’ orbits were “very near to the targeted orbits,” according to a statement from the space agency.

Following separation, EOS-04’s two solar arrays were autonomously deployed, and the Isro Telemetry Tracking and Command Network (ISTRAC) in Bengaluru took control. In a few days, the satellite will be manoeuvred to its final location and begin transmitting data.

The Earth Observation Satellite-04, also known as the Radar Imaging Satellite (RISAT), was built to deliver high-quality photographs in all-weather circumstances for applications including agriculture, forestry, plantations, flood mapping, and soil moisture and hydrology. The spacecraft will gather data in the C-Band band, completing observations made by the Resourcesat, Cartosat, and RISAT-2B series. The satellite has a ten-year operational life.

The INSPIRESat-1 student satellite, weighing 8.1 kilogrammes, was created by the Indian Institute of Space Science and Technology in collaboration with the University of Colorado’s Laboratory of Atmospheric and Space Physics. The satellite will help us better understand the dynamics of the ionosphere and the sun’s coronal heating process. It has a one-year operating lifespan.

In addition to mapping vegetation, the spacecraft will carry the INS-2DT technology demonstration satellite, which includes a thermal imaging sensor and can aid in the evaluation of land and ocean surface temperatures.

The Indian Institute of Space Science and Technology, the University of Colorado in the United States, Nanyang Technological University in Singapore, and National Central University in Taiwan collaborated on the third InspireSat-1 satellite. This spacecraft will examine ionosphere dynamics and the Sun’s coronal heating process using two instruments.

The first launch of 2022 has triggered Isro’s plans to launch 18 more missions this year, including the high-profile Chandrayaan-3 mission to the Moon and the long-awaited uncrewed Gaganyaan mission.

The PSLV, India’s workhorse launcher, climbed to the top of the SSO on its 54th trip. The PSLV-C53 mission, which will launch OCEANSAT-3 and INS 2B ANAND into orbit, is scheduled to launch in March.

S Somnath, the Isro’s chief, has stated that the agency will launch five significant satellites in the next three months and a total of 19 missions this year.
