So Close Yet So Far Chirag Mehrotra Copy Editor On Jul. 22, the Indian Space Research Organization (ISRO), launched India's second mission to the moon: Chandrayaan-2. The craft consisted of three components, the lunar orbiter, the lander Vikram, named after Vikram Sarabhai father of the Indian Space Program, and a rover Pragyan meaning wisdom. The craft held hopes and dreams of a billion people as it endeavored to be the first country to attempt a soft-landing on the Moon's South Pole. After spending 28 days hurtling through space, the craft reached the moon's orbit. From there it spent the next few days for prepping the lander to detach and land on the lunar surface. On Sept. 7 at 1:38 a.m., Indian Standard Time (IST), 4:18 p.m. EST, Vikram began its descent to the lunar surface. All seemed to be normal until 2.1 kilometers (1.2 miles) above the moon’s surface when the lander deviated from the planned trajectory for the soft landing. With that, a billion people waited anxiously to hear the news about what happened to the lander. People were in a shock when K. Sivan, chairman of ISRO, released a statement, “Vikram’s descent was as planned and normal performance was observed up to an altitude of 2.1 km. Subsequently, communication from Lander to the ground stations was lost. Data is being analyzed." ISRO had 14 days to re-establish contact with the lander, which is equivalent to one lunar day before the region entered a lunar night, where temperatures drop to -200 degrees Celsius. The instruments were not designed to withstand those temperatures for a prolonged amount of time. Those 14 days ended on Sept. 20 and Vikram was never heard from again. NASA flew a Lunar Reconnaissance Orbiter (LRO) over the planned landing site and took pictures of the region. However, what happened to the lander is still a mystery, since much of the terrain is covered in shadows and does not show the lander's condition. The LRO will pass over the region again on Oct. 14 during a lunar day. Hopefully, this will finally allow us to learn what happened to the lander. After two failed mission, Israel's Beresheet Program, the race is still on to the Moon's South Pole. Only time will tell if India or any other country will ever land in the region and answer countless questions we have about our celestial neighbor. Until then, we can only hope.
