Question

An American astronaut, Neil Armstrong, was the first person to walk on the Moon. He made his historic Moon walk in 1969. Several decades have passed since the Apollo astronauts walked on the Moon. What do you think is the farthest distance humans can travel in space?

State the answer you think best describes the farthest distance astronauts can travel if they were leaving Earth with our current-level of technology.
A) into the up per part of Earth’s atmosphere
B) about a quarter of the way to the Moon
C) about half way to the Moon
D) to the Moon
E) slightly past the Moon
F) halfway t o Mars
G) to Mars
H) slightly past Mars
I) almost halfway through our Solar System
J) to a nearby star
K) to another planetary system
L) to another galaxy
Explain your thinking. How did you decide how far recent astronauts have traveled?

Answer 1

The farthest distance humans can travel in space with our current-level of technology is to the Moon (D). The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970. This record has stood untouched for over 50 years!

I decided this answer by looking at the historical data of human spaceflight and the current capabilities of our rockets and spacecraft. The Moon is the only celestial body that humans have landed on and returned from. No human has ever traveled beyond the Moon or to another planet. The closest star to the Sun, Proxima Centauri, is about 4.2 light-years away, which means it would take over 8,000 years to reach it with the fastest spacecraft ever. The edge of the solar system is even farther, at about 122 astronomical units (AU) or 18 billion kilometers (11 billion miles) away. Therefore, with our current-level of technology, we cannot travel very far in space compared to the vastness of the universe.
