The news of Chandrayaan-2's Vikram lander being located on the lunar surface by ISRO on 8 September 2019 has lent a ray of hope among Indians of the space agency re-establishing contact with the module. Netizens expressed a range of sentiments - pride, curiosity, hope and patriotism and many shared pictures of the lander or the Indian tricolour.
 
 
What
  1. India's bold mission to soft-land on the moon suffered a setback with the 'Vikram' module losing communication with ground stations, just 2.1 km from the lunar surface during its final descent in the early hours of 7 September 2019.
  2. Considered as the "most complex" stage of the country's second expedition to the moon, the lander was on a powered decent for a soft landing when it lost contact.
  3. The image of the lander's rover 'Pragyan' is housed inside it was captured by the camera of Chandrayaan-2's orbiter, which is healthy, safe and functioning normally in the intended orbit around the Moon, the space agency said.
  4. In the early hours of 7 September 2019, countless Indians had sat glued to their television sets, praying for a successful landing of Vikram, but it soon turned into a heartbreak despite the module coming tantalising close to the lunar surface.
Flashback
  1. The 1,471-kg lander of Chandrayaan 2 — the first Indian mission to explore the lunar terrain with home-grown technology — is named Vikram after Dr. Vikram A. Sarabhai, the father of the Indian space programme.
  2. The lander was designed to execute a soft-landing and to function for one lunar day, which is equivalent to about 14 earth days.
  3. The 27-kg Pragyan (which translates to ‘wisdom’ in Sanskrit) is a six-wheeled robotic vehicle. It is designed to travel up to 500 metres from the landing spot and leverage solar energy for its functioning.
  4. The lander carried three scientific payloads to conduct surface and subsurface science experiments, while the rover carried two payloads to enhance our understanding of the lunar surface.
  5. The mission life of the orbiter will be one year while that of the rover was to be one lunar day which is equal to 14 earth days.
  6. The Vikram Lander, carrying the Pragyaan Rover, had separated from the orbiter on September 3. The orbiter was functioning normally. 
  7. The orbiter, which weighs nearly 2,379 kg, is expected to go around the moon for one year. Its payloads will conduct remote-sensing observations from a 100 km orbit.
  8. The Orbiter is tasked with taking pictures of the moon and relaying them back to ISRO to help scan and map the lunar surface for further experiments.
  9. The Vikram Lander lost contact 13 minutes after its descent. It failed to bring down its speed from around 6,048 km per hour to about 7 km per hour.
