NASA says it can’t afford to build a space telescope considered the fastest way to identify asteroids that might impact the Earth with terrible consequences.
On April 24, 2019, NASA’s Mars Odyssey orbiter captured a new thermal image of Phobos, the larger of Mars’ two moons. Each color in the full-moon image represents a temperature range detected by Odyssey’s Thermal Emission Imaging System (THEMIS) camera.
The phenomenon creates warmer, drier conditions in some tropical regions that mimic future climate change
The odds of impact are low, but the stakes couldn’t be higher
