Info-paedia : Exploration of the Moon: Pioneering Lunar Missions and Ongoing Endeavors
1. Lunar Reconnaissance Orbiter | 2009
In 2009, NASA's Lunar Reconnaissance Orbiter was launched with the goal
of creating a comprehensive 3D map of the moon's surface. Its mission
included identifying potential landing sites crucial for both robotic and
human missions. Over time, its mission scope expanded to focus on the polar
region, known to harbor water resources. A significant observation was the
movement of water molecules around the dayside of the moon.
2. Yutu-2 Rover | 2018
The China National Space Administration introduced the Yutu-2 rover in
2018, marking the first successful soft landing on the far side of the moon.
A groundbreaking achievement, the rover ventured into the Von Kármán crater
in 2019 to investigate the early solar system and Earth's origins. Notably,
it unveiled the distinct characteristics of the soil on the far side, which
is both stickier and less rocky compared to the near side.
3. Chandrayaan-2 Orbiter | 2019
In 2019, the Indian Space Research Organisation (ISRO) launched
Chandrayaan-2, a mission comprising an orbiter, lander, and rover. While the
lander's soft landing attempt faced setbacks, the orbiter persevered,
actively mapping lunar topography, studying mineral composition,
investigating the lunar exosphere, and seeking indicators of water ice
presence.
4. Chang'e 5 Orbiter | 2020
China's Chang'e 5 mission took off in March 2020, employing a
multi-module approach with an orbiter, lander, ascender, and 'returner'. The
mission's accomplishment lay in successfully collecting and returning
approximately 2 kg of lunar samples, a feat achieved in December 2020. The
orbiter later embarked on a journey toward the Sun-Earth Lagrange point L1
for solar observations.
5. Korea Pathfinder Lunar Orbiter | 2022
South Korea entered lunar exploration by launching its first orbiter in
August 2022. Tasked with studying the moon's surface, the orbiter gathers
data to inform future missions, particularly focusing on the polar region.
It aims to uncover evidence of ice deposits, monitor seasonal variations,
and assess crater terrains.
6. Capstone Orbiter | 2022
NASA's Capstone, a satellite comparable in size to a microwave,
initiated a new chapter in lunar exploration in 2022. Its maiden voyage
aimed to test an elliptical lunar orbit called the near rectilinear halo
orbit. Beyond this, Capstone aspires to showcase spacecraft-to-spacecraft
navigation services, offering potential stability to long-term projects like
Gateway under NASA's Artemis program.
Chandrayaan – 3 | 2023
Chandrayaan-3 is the third, most recent and successful Indian lunar
exploration mission under the Chandrayaan programme by ISRO. It consists of
a lander named Vikram and a rover named Pragyan similar to those of the
Chandrayaan-2.
