Understanding the Chandrayaan-1 Launch Date
The question asks about the year in which the Indian Space Research Organization (ISRO) successfully launched its first lunar mission, known as "CHANDRAYAAN-1". Understanding the history of India's space exploration is key to answering this question.
Chandrayaan-1 Mission Overview
Chandrayaan-1 was India's first unmanned lunar exploration mission. It was designed to orbit the Moon and conduct scientific experiments using various instruments carried onboard. A key objective was to create a high-resolution map of the Moon's surface and study its mineralogy and chemical composition. The mission also notably confirmed the presence of water molecules on the Moon.
Analyzing the Launch Date of Chandrayaan-1
The Chandrayaan-1 spacecraft was successfully launched by ISRO. The launch date is a significant event in India's space history.
- The launch vehicle used for Chandrayaan-1 was the Polar Satellite Launch Vehicle (PSLV-XL C11).
- The launch took place from the Satish Dhawan Space Centre, Sriharikota.
- The exact launch date of the Chandrayaan-1 mission was 22nd October 2008.
Let's look at the given options:
- (a) 22nd October 2009: This date is one year after the actual launch.
- (b) 22nd October 2010: This date is two years after the actual launch.
- (c) 22nd October 2008: This is the correct launch date for Chandrayaan-1.
- (d) 22nd July 2019: This date corresponds to the launch of a later mission, Chandrayaan-2.
Therefore, the correct year for the launch of Chandrayaan-1 is 2008.
| Event | Date |
|---|---|
| Launch Date | 22nd October 2008 |
| Entered Lunar Orbit | 8th November 2008 |
| Mission Concluded | 29th August 2009 |
Based on the historical records and ISRO's official information, Chandrayaan-1 was indeed launched on 22nd October 2008.

Additional Information: ISRO Space Exploration
ISRO, the Indian Space Research Organization, is India's national space agency. Besides the successful Chandrayaan missions to the Moon, ISRO has undertaken several other notable space exploration endeavors:
- Mars Orbiter Mission (MOM) / Mangalyaan: India's first interplanetary mission, launched in 2013, which successfully entered Mars orbit.
- ASTROSAT: India's first dedicated multi-wavelength space observatory, launched in 2015.
- Aditya-L1: India's first solar mission, launched in 2023, to study the Sun.
- Gaganyaan: ISRO's project to demonstrate human spaceflight capability.
These missions highlight ISRO's growing capabilities in space technology and exploration.
