India has landed its Chandrayaan-3 spacecraft on the moon, becoming only the fourth nation ever to accomplish such a feat. The mission could cement India’s status as a global superpower in space. Previously, only the United States, China and the former Soviet Union have completed soft landings on the lunar surface. Chandrayaan-3’s landing site is also closer to the moon’s south pole than any other spacecraft in history has ventured. The south pole region is considered an area of key scientific and strategic interest for spacefaring nations, as scientists believe the region to be home to water ice deposits. The water, frozen in shadowy craters, could be converted into rocket fuel or even drinking water for future crewed missions. Indian Prime Minister Narendra Modi, currently in South Africa for the BRICS Summit, watched the landing virtually and shared broadcasted remarks on the livestream. Just a few days ago, on Aug. 19, Russia’s Luna 25 spacecraft crashed into the moon after its engines misfired, ending the country’s first lunar landing attempt in 47 years. As Chandrayaan-3 approached the moon, its cameras captured photographs, including one taken Aug. 20 that India’s space agency shared Tuesday. The image offers a close-up of the moon’s dusty gray terrain. India’s lunar lander consists of three parts: a lander, rover and propulsion module, which provided the spacecraft all the thrust required to traverse the 384,400-kilometer void between the moon and Earth. The lander, called Vikram, completed the precision maneuvers required to make a soft touchdown on the lunar surface after it was ejected from the propulsion module. Tucked inside is Pragyan, a small, six-wheeled rover that will deploy from the lander by rolling down a ramp. Vikram used its on-board thrusters to carefully orient itself as it approached the lunar surface, and it slowly throttled down its engines for a touchdown just after 6 p.m. IST Wednesday. The Indian Space Research Organization, or ISRO, later confirmed it had established two-way communication with the spacecraft and shared the first images of the surface captured during the lander’s final descent. With the success of Chandrayaan-3, India became the second country to land a spacecraft on the moon in the 21st century after China, which has put three landers on the lunar surface since 2013 — including the first to touch down on the moon’s far side.
