When Falcon Heavy lifts off, it will be the most powerful operational rocket in the world by a factor of two. With the ability to lift into orbit nearly 64 metric tons (141,000 lb)---a mass greater than a 737 jetliner loaded with passengers, crew, luggage and fuel--Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost.

Scientists have revealed fresh evidence of water on the surface of Jupiter’s moon Europa, raising hopes that alien life may be found around the second planet from Earth. Europa’s frozen surface has long been thought to cover a salty ocean about twice the size of our planet’s. Given the suspected abundance of warm, liquid water under its miles-thick ice shell, the moon is considered a “top candidate” by NASA for life on a Solar System body other than Earth. Europa has long been a high priority for exploration because beneath its icy crust lies a salty, liquid water ocean. NASA’s Europa Clipper, targeted to launch in 2022, will be equipped with the instruments necessary to determine whether Europa possesses the ingredients necessary to support life as we know it.
