Many, many decades ago, the former Soviet Union launched Luna 12 spacecraft to orbit around the moon to study its chemical composition, gravitational anomalies, and more. The Luna 12 spacecraft orbited around the moon for 3 months. The spacecraft collected enormous information for future Lunar missions that are of immense help even to this day! The Lunar gamma and X-ray emissions and meteorite streams were collected. These findings are successfully furthering various Lunar missions. Added to these, the Luna 12 was fitted with a Television as it transmitted hundreds of pictures of the Lunar Surface!
However, the success of Chandrayaan will always be fresh in our memories as it heralded a successful Lunar mission of our country.
