The Indian Space Research Organization’s unmanned drone, also called Mangalyaan, was programmed by Indian engineers to fire its main engine and eight smaller thrusters for 24 minutes in order to make the spacecraft's final maneuvers into Mars' orbit.
The spacecraft has executed the arrival sequence autonomously with engineers receiving the telemetry with 12-and-a-half minute delay at ISRO's control center in Bangalore due to the 139 million miles separating Earth and Mars.
“History has been created today,” said Indian prime minister Narendra Modi. “We have dared to reach out into the unknown and have achieved the near-impossible. I congratulate all ISRO scientists as well as all my fellow Indians on this historic occasion.”
On the orbit, the unnamed probe is set to study Mars’ surface and scan its atmosphere for evidence of some sort of life. The probe is expected to circle Mars for six months, about 500 kilometers (310 miles) from its surface. Its five scientific instruments will collect data and send it back to Earth, RT reported.
