After traveling through space for more than two years and over two billion miles, NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at its destination, asteroid Bennu, on Monday, Dec. 3, 2018. The spacecraft will spend almost a year surveying the asteroid with five scientific instruments with the goal of selecting a location that is safe and scientifically interesting to collect the sample. OSIRIS-REx will return the sample to Earth in September 2023.

Two vastly different NASA spacecraft are about to run out of fuel: The Kepler spacecraft, which spent nine years in deep space collecting data that detected thousands of planets orbiting stars outside our solar system, and the Dawn spacecraft, which spent 11 years orbiting and studying the main asteroid belt's two largest objects, Vesta and Ceres.
However, the two record-setting missions have more in common than their coincidentally low fuel levels. Both missions gathered data that broke new scientific ground, searching for answers inside and outside our solar system.

Did you ever notice how the air can seem cooler when you enter a forest? Humans aren’t the only living things that sweat to cool off. When trees and plants “sweat,” they cool themselves andcan cool the surrounding air.Through a process called transpiration,water and nutrients are taken up by plant roots from soil and delivered to the stem and leaves as part of photosynthesis.
