The Indian Space Research Organization (ISRO) launched its intelligence satellite EMISAT as well as 28 more satellites from various other nations on Monday. This included 24 from the United States too. India’s intelligence satellite EMISAT was carried by ISRO’s PSLV C45 which was lifted from Satish Dhawan Space Centre. The mission is going to see ISRO putting payloads in three orbits as well as conducting various space experiments for the very first time.
The intelligence satellite EMISAT is an intelligence satellite which aims towards electromagnetic measurement. ISRO’s third-generation workhorse PSLV (Polar Satellite Launch Vehicle) was used for the launch and was the 47th flight of PSLV. This mission marks the space agency’s numerous firsts because it will be maneuvering satellites in multiple orbits and experiments on maritime satellite applications and many others will also be conducted. The rest of the 28 international satellites are one 2U type, two 6U type and twenty-five 3U type nano satellites from the U.S. (24), Switzerland (1), Spain (1) and Lithuania (2). Commercial arrangements have been made for launching these satellites and a brand new model of PSLV-Ql rockets equipped with 4 strap-on motors have been used in the first step of the launch.
The Successful Legacy of PSLV
Two major missions of India, namely, Chandrayan in 2008 as well as Mars Orbiter in 2013 also used PSLV. It is ISRO’s versatile and reliable launch vehicle and has made 39 consecutive flights so far.
During this move, the rest of the 28 customer satellites which weighed around 220 kgs were also released to approximately 504 km orbit. The fourth stage will lower to 485 km orbit for serving as the orbital platform to carry out space-related experiments for the very first time in the history of ISRO.
ISRO’s Achievements in This Year till Now
Interestingly, it is for the first time that ISRO has envisaged for providing a micro gravity environment for the research organization and the academic institutions for performing experiments. The earlier ISRO launches of 2019 so far include the launch of GSAT031, the communication satellite of India from Ariance in February and the launch of Microsat-R, the imaging satellite, for military purposes along with a 1.2 kg Kalamsat in the month of January.
