Scientists: Mars’ Former Life-Supporting Habitat Helped By Comets
When Mars was being bombarded with giant asteroids and comets over four billion years ago, the giant space rocks were enhancing the climate. A new study from the University of Colorado Boulder says that the comets and asteroids actually enhanced the climate enough to make Mars’ environment more conductive to life for a time. According to NBC News: The bombardment occurred during a period known as the Late Heavy Bombardment, which was about 3.9 billion years ago when the solar system was developing.
