## What is Mearth?

Have you ever wondered what the temperature currently is on Mars or the Moon? Is there anywhere on Earth that has a similar temperature?

This app gets data from the Curiosity rover on Mars from NASA, estimates the Moon temperature at the Apollo 11 landing site Tranquility Base, and compares them to locations on Earth that have similar temperatures to Mars.

Based on our 2013 SpaceApps Challenge: https://2013.spaceappschallenge.org/project/mearth
