How Long Does It Take to Get to the Moon?

If you’re dreaming of a weekend getaway to the lunar surface, you’re probably wondering how long it takes to get to the Moon. While we may not have lunar resorts just yet, NASA’s Artemis mission aims to take us back to the Moon by building the Lunar Gateway, a space station in lunar orbit that will serve as a staging post for future trips.

How Far Away is the Moon?

The Moon’s distance from Earth isn’t fixed. Just as the Earth’s orbit around the Sun isn’t a perfect circle, the Moon’s orbit around the Earth also varies. At its closest point (perigee), the Moon is about 363,104km away from Earth, and at its farthest point (apogee), it is approximately 405,696km away. On average, the distance between the Earth and the Moon is around 384,400km.

How Long Does It Take to Get to the Moon?

The exact duration of a trip to the Moon is difficult to determine due to several factors. These include the changing distance between the Earth and the Moon, the trajectory of the spacecraft during take-off, whether the craft is manned or unmanned, the propulsion system used, and the purpose of the mission (landing, orbiting, or flyby).

During NASA’s Apollo program, the fastest mission, Apollo 8, took 69 hours and 8 minutes to enter lunar orbit. Subsequent Apollo missions lasted for 74 hours or more. The final Moon-landing mission, Apollo 17, took 86 hours and 14 minutes to reach the Moon.

The Artemis 1 mission in 2022, an unmanned craft, took five days to reach the Moon’s orbit. The travel time has increased over the years as direct transfer trajectories have been replaced with more fuel-efficient routes to save costs.

How Long Did It Take to Get to the Moon in 1969?

In 1969, during the Apollo 11 Moon-landing mission, it took astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins approximately 75 hours and 49 minutes to reach and land on the Moon. This duration refers to the time it took for them to land on the Moon, not just enter its orbit.

According to NASA, the complete duration of an Apollo mission, from leaving Earth to returning home, was around eight days, three hours, 18 minutes, and 35 seconds. Here are the durations of the Apollo missions to the Moon:

  • Apollo 8: 69 hours, 8 minutes (1968)
  • Apollo 10: 75 hours, 55 minutes (1969)
  • Apollo 11: 75 hours, 49 minutes (1969)
  • Apollo 12: 83 hours, 25 minutes (1969)
  • Apollo 13: 76 hours (1970)
  • Apollo 14: 81 hours, 56 minutes (1971)
  • Apollo 15: 78 hours, 31 minutes (1971)
  • Apollo 16: 74 hours, 28 minutes (1972)
  • Apollo 17: 86 hours, 14 minutes (1972)

How Long Does It Take a Probe to Get to the Moon?

A probe can reach the Moon in approximately eight and a half hours. For example, the New Horizons probe took eight hours and 35 minutes to reach the Moon before eventually continuing its journey to Pluto, which took nine years.

However, the travel time for other probes can vary significantly depending on factors such as the propulsion system used and the amount of fuel available. The European Space Agency’s Smart-1 probe, which used electric-ion propulsion and only 82kg of Xenon fuel, took about one year and six weeks to reach the Moon in 2003.

FAQs

Q: Can I travel to the Moon as a tourist?
A: While lunar tourism is not yet possible, NASA’s Artemis mission aims to make travel to the Moon a reality in the future by establishing the Lunar Gateway as a stepping stone for exploration.

Q: How can I keep track of upcoming Moon missions?
A: You can stay informed about upcoming Moon missions and other space-related news by visiting the official iBlog website.

Conclusion

While planning your lunar getaway, remember that it takes just over three days to reach the Moon. The distance between the Earth and the Moon, combined with various mission factors, determines the exact duration of the journey. As we look forward to future space exploration, we can expect more exciting missions and discoveries in the realm beyond our planet.
