Have you ever wondered why Chandrayaan 2 is taking 48 days to reach the Moon while Apollo 11 just took 4 days? NASA's Apollo 11 was the fastest trip to Moon, which took only 4 days, 6 hours & 45 minutes. Chandrayaan 2 is taking over a month. This is because of the build of the rocket, the amount of fuel it is carrying & speed of the lunar craft. Chandrayaan 2 is the most cost-effective way to travel to the Moon.
