* Space travel is expensive! For their trip to the Moon, the Apollo astronauts’ living quarters were only 213 cubic feet (that’s smaller than a typical bathroom in a house). How many dollar bills could fit in there?

@ Would a stack of dollar bills in the amount of the U.S. national debt reach from the Earth to the Moon? Show your calculations to receive any credit!

@ Pluto has been hard to measure from Earth because of its atmosphere. In 2007 Young, Young, and Buie measured Pluto as having a diameter of 2322 km. The New Horizons probe traveled to Pluto and measured it up close and we now know the actual size is 2372 km. What was the percent error of the 2007 measurement?

1. Space travel is expensive! For their trip to the Moon, the Apollo astronauts' living quarters were only 213 cubic feet (that's smaller than a typical small bathroom in a house). How many dollar bills could fit in there? The room in the top half of the image is the laboratory. At the lower left is the sleeping area, lower center is bathroom, and lower right is the living area. (Image from NASA). 2. Would a stack of dollar bills...

During the Apollo missions, astronauts traveled from the Earth to the Moon and back. When they were close to Earth, gravity accelerated them toward Earth, but when they were close to the Moon, gravity accelerated them toward the Moon. However, there is a point somewhere between the Earth and the Moon where they experienced no acceleration due to gravity. The Earth is 6.0×1024 kg, the Moon is 7.3×1022 kg in mass, and the two are 3.8×108 m apart. How far...

Two astronauts are on a space station preparing for a mission to Mars. The space station is powered by the combustion of a mixture of gases released from the high pressure container in which they are both contained. When not in use, the high pressure gas canister is stored in the far corner of the station away from the crew. One of the two gases possesses a high molecular weight, has a strong foul odor but is harmless to humans...
