Chandrayaan 2 highlights: Chandrayaan-2, India’s second lunar exploration mission, went through its second lunar bound orbit manoeuvre today. The orbit manoeuvre took place at 12:50 hours IST, using the onboard propulsion system, ISRO said.

The spacecraft got successfully placed in the orbit of the Moon on Tuesday, August 20. The spacecraft will touch down on the Moon’s surface on September 7.

Prime Minister Narendra Modi congratulated the team of ISRO, saying the latest manoeuvre was an “important step in the landmark journey to the Moon.”

There will be four more orbit manoeuvres to enable the spacecraft to enter into its final orbit passing over the lunar poles at a distance of about 100 km from Moon’s surface. Subsequently, the Vikram lander will separate from the orbiter on September 2. Since its launch on July 22, Chandrayaan-2 spacecraft has been in the orbit of the Earth. So far, the spacecraft has raised its orbit five times from July 23 to August 6.

According to ISRO, Chandrayaan2 will shed light on a completely unexplored region of the Moon, the South Pole. The mission’s success will make India, the fourth country after Russia, the US and China to make a soft landing on the Moon.

    OPINION | It was the genius of Vikram Sarabhai which has brought us Chandrayaan

    With Chandrayaan 2, India joins the small select club of nations which have major space missions on their CV. It is much more important than even the nuclear capability. It shows that India is able to meet the high standards of space technology. It was the genius of Vikram Sarabhai which launched India on the fast track, which has brought us Chandrayaan.

    Chandrayaan-2: Manoeuvres so far

    SO FAR, since its launch on July 22, Chandrayaan-2 had been orbiting the Earth, moving into higher and orbits. This is achieved by a series of “Earth-bound orbit-raising manoeuvres”. There were five such manoeuvres before the mission left Earth orbit on Wednesday. These raised the orbits around Earth successively to 230 × 45,163 km (July 24), 251 × 54,829 km (July 26), 276 × 71,792 km (July 29), 277 × 89,472 km (August 2) and 276 × 1,42,975 km (August 6). The two figures with each orbit refer to the distance at the nearest and farthest points.

    Chandrayaan-2 entered Lunar Transfer Trajectory on August 14

    Chandrayaan2, launched on July 22 by GSLV MkIII-M1 vehicle, had entered the Lunar Transfer Trajectory on August 14 after final orbit raising manoeuvre of the spacecraft was successfully carried out.

    The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.
    All systems on board Chandrayaan2 spacecraft are performing normal, ISRO said on August 14.

    Chandrayaan-2 to enter Moon's orbit today

    Chandrayaan-2 will enter the orbit of the Moon between 8.30 am and 9.30 am today. Track this space for real-time updates on the important development in India's lunar exploration mission. 

    Since its launch on July 22, Chandrayaan-2 spacecraft had been in the orbit of the Earth. There were a series of orbit-raising, the spacecraft progressed five times on the orbit from July 23 to August 6 before it left the Earth’s orbit this week when the final orbit-raising was done. In fact, the Indian Space Research Organisation (ISRO) had earlier this month released the first set of images of Earth captured by Chandrayaan-2.

    The spacecraft will be needed to go through another four stages of the orbit manoeuvering to get into the last orbit. This process of manoeuvering in the lunar orbit will be taking place from August 21 to September 1.

    Once the spacecraft reaches the final orbit of the Moon, it will be separating the Vikram lander from itself on September 2. The Vikram lander will then go through two more orbit manoeuvers before the initiation of powered descent to make the soft landing on the surface of the Moon on September 7.

    The Vikram lander will be landing on the southern pole of the Moon which has so far been unexplored. According to the ISRO, the Moon’s surface in the south pole is in the shadows more than the surface in the north pole. After it successfully lands, the spacecraft will rollout the rover for exploring the surface of the Moon there.
