isro set to launch pslv-c34 into space

• The space agency sent 10 satellites into orbit in a single mission in 2008

• The total weight of all the 20 satellites is about 1,288 kgs

• PSLV-C34 to take off at 9.25 a.m. from Satish Dhawan Space Centre in Sriharikota

BANGALORE, India – The Indian Space Research Organisation (ISRO) will send Polar Satellite Launch Vehicle (PSLV-C34) into space at 9.25 a.m. from Satish Dhawan Space Centre in Sriharikota on June 22.

ISRO declared that the vehicle will not only put 20 satellites into the same orbit, but the voyage would be important for a manoeuvre that ISRO will be conducting.

Reports claimed that once the satellites are injected into the orbit from the fourth stage of the vehicle, fifty minutes later, its engine will be re-ignited for five seconds.

Then, it will be shut down again for 50 minutes and re-ignited for another five seconds. This trick was previously performed on December 16, 2015.

After the PSLV-C29’s fourth stage put six Singapore satellites into the same orbit, the vehicle re-started the fourth-stage engine for four seconds.

According to the Director of the Vikram Sarabhai Space Centre based in Thiruvananthapuram, K. Sivan, who is heading this operation, these moves will help master the ability to inject satellites into different orbits but with the same rocket.

Reports stated that if PSLV-C34 is able to perform this experiment without any hitches, researchers will work on performing it again in the future to send satellites to different orbits, in the same rocket. It will make space journey far simpler and reduce the number of rockets sent for satellite placements, experts opined.

Dr. Sivan said in a statement, “After each satellite is injected into orbit, the vehicle will be re-oriented if required and the next satellite will be put into orbit with a varying velocity so that the distance between the satellites grows monotonically. We will do this to ensure that there is no collision of satellites. Then, after a huge gap of 3,000 seconds, PS-4 [the fourth stage] will be re-ignited for five seconds. Then, it will be switched off for another 3,000 seconds. It will be re-ignited for another five seconds.”

ISRO cleared the 48-hour countdown to the June 22 voyage and said that the total weight of all the 20 satellites is about 1,288 kg with co-passenger satellites from the U.S., Canada, Germany and Indonesia as well as two satellites from Indian Universities.

One of its satellite, SCATSA-1 will be stationed for weather forecasting and cyclone identification.

So far, the space agency has sent ten satellites into orbit in a single mission that took place in the year 2008. The satellites were, however, deployed in the same orbit.
