- What mechanism transfers heat away from the surface of the Moon? If the Moon is losing energy in this way, why does it not simply become colder and colder?arrow_forwardPrompt: You are on the Sensor and Data Acquisition engineering team for the new NASA space rover program: the Unmanned Mobile Assessment Drone for Basic Reconnaissance and Observation. Your team is working with a very low budget, and have been given a hand-me-down drone which was repurposed from an old Mars mission. The drone has already landed successfully on Saturn. It’s first task was to travel 4.6 m to a rock and then use it’s built in drill to take a sample. Unfortunately, it appears that the drone stopped very short, only traveling 1.32 m instead of the 4.6 m. Everything about the ultrasonic distance sensor that the drone uses to move with seems to be operating correctly. When you requested details from the drone, it said that the time it took for the 40 kHz ultrasonic sound wave to travel to the rock and back was 0.0108 seconds. Why did the drone only travel 1.32 m, given the 0.0108s echo time?arrow_forwardLearn about an ongoing or upcoming expedition to investigate the atmosphere of one of the terrestrial planets (including Earth).

- Which of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system? Check the TWO items that apply. a It has a thick atmosphere, made mostly of nitrogen. b It has the darkest, least reflective surface of all the known planetary bodies. c It is the brightest (i.e. most reflective) object in the solar system. d The entire surface is more heavily-cratered than any other body in our solar system. e Its surface is very smooth in some places.arrow_forwardA surprisingly large number of people in the world don’t believe that astronauts havewalked on the Moon. They believe the Moon landing to have been a hoax. One argumentthey use is that if there are astronaut footprints on the Moon, we should be able to seethem using a powerful telescope. The fact that we do not, they say, is evidence that theywere never there.The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbitingthe Moon. The LRO gets as close as 35 km to the Moon’s surface. The diameter ofthe camera’s primary mirror is 195 mm. If the camera is sensitive to optical light at awavelength of 600 nm, show that it would not be able to spatially resolve a foot print ofphysical length 30 cm when it is 35 km above the Moon’s surface.Tip: You’ll need to calculate the angular size of the footprint, as seen from a height of35 km. θ = S/D, where S is the physical size of the footprint and D = 35 km, is theangular size of the footprint in radians.arrow_forwardWhile looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.arrow_forward
