Investigation 7, Part 2 How Far/How Fast
Warm up: • What are some important questions that you formed about your journey to the moon? List 2 or 3 of the most important things you need to figure out before you go?
Distance and Speed • One of the questions yesterday was how long the Lunar mission would take. • This question is very important in planning for supplies like food and fuel. • Distance vs. Speed • The distance to the Moon will not change, so in order to shorten the trip, we have to travel faster.
How Long will it take us? • Get out your calculators. • The distance from the Earth to the Moon is 384,000 km. • The scientists at NASA designed the Apollo rockets to travel 5700 km per hour. • How long will it take you to get there? • 67.37 hours. Just over 67 hours. • There are other things to consider too. • Time in Earth orbit to prepare to head to the Moon. • Travel time from Earth orbit to the Moon. • Time spent on the Moon. • Time spent traveling back.
More details • It took Apollo astronauts about 2 hours to take off from Cape Canaveral in Florida and complete their preparations for travel to the Moon while in Earth “Parking Orbit.” • They then fired their rockets for their trip to the Moon and navigated into Moon orbit for the duration of their stay. • Rockets were fired again for their return to Earth and the “Splashdown” landing.
How Long? • Think about the time to travel 384,000 km each way, parking orbit time and time on the Moon for your work. • How long should you plan your trip for? Write this in your journals. • Share your answers. Do the trip times seem reasonable? • 67 there and 67 back, plus 2 hour parking orbit is how many days? • Just over 5 and a half. • How long do you want to work on the Moon? • Remember, you will have to transport food and materials for the length of your stay. • Now watch second 20 minutes of “For All Mankind.”
