Chandrayaan-2 has successfully entered the orbit of the moon and is now approaching its destination. In a very difficult maneuver, the Indian organization for space research (ISRO) carried out on Tuesday the insertion into lunar orbit of lunarcraft grown at home.

In order to place Chandrayaan-2 in its planned orbit, ISRO triggered the Lunar Orbit (LI) insertion between 8:34 and 9:02, ending 28 minutes of firing of the engines. Now that the mission is in orbit around the moon, it will move to a different orbit in the next 10 days, before its 'soft landing' on 7 September.

While he was addressing a press conference on Tuesday, ISRO leader, K. Sivan, spoke about the most terrifying 15 minutes during which Chandrayaan-2 went on the ### ### ### ############################>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Lunar orbit. He said, "For 30 minutes, our heart almost stopped by performing today's maneuver (LOI). All our eyes were focused on control systems, checking the health of the systems … We were so anxious … And we are more terrified now (about the 15-minute landing maneuver) … Once the motorized descent begins, we have "We have done all possible simulations, for systems and subsystems, all that is humanly possible."

For the mission to be successful, it must move at exactly the same speed, gradually slowing down as it approaches the predetermined distance and inclination between its orbit and the moon. Currently, all operations are managed by the orbiter propulsion system, but once the Lander are separated on September 2, Vikram will be autonomous.

The landing site was chosen with care. It has a slope of 12 degrees, because nothing above that could overturn the lunarcraft. After the rover, Pragraan unfolds and moves on the lunar surface at the speed of one penny per second. Covering a distance of about 500 meters in a single lunar day, this equates to 14 days 'Earth'. The mission will be powered by batteries running on solar energy from September 7 to 21. After the fortnight, the lander will not be able to remain loaded because the lunar night prevails.

However, K. Sivan said that ISRO might consider recharging its batteries from solar energy when it will be daylight on the moon after 14 days, beyond the first week of the year. October. This is a bit possible if sensors and other systems are not affected by extreme temperatures.
