Indian Space Research Organisation has successfully reignited the fourth stage of its workhorse Polar rocket during the
PSLV-C29 mission after putting in orbit six Singapore satellites, agency officials said in Thiruvananthapuram today.
The engine in the upper stage of the PSLV was shut off and re-started after placing the satellites in orbit yesterday, ISRO's
Liquid Propulsion Systems Centre (LPSC) Director S Somanath said.
The PSLV-C29 injected the six Singapore satellites in orbit completing the exercise in about 21 minutes after it blasted off
from the spaceport of Sriharikota, about 110 km from Chennai last evening.
