We’re about to find many more interstellar interlopers—here’s how to visit one
A few days ago, an inscrutable interstellar interloper made its closest approach to Mars, where a fleet of international spacecraft seek to unravel the red planet’s ancient mysteries. Several of the probes encircling Mars took a break from their usual activities and turned their cameras toward space to catch a glimpse of an object named…

After leading NASA’s mission to Pluto, Alan Stern flies to space himself
It has been fun to watch Virgin Galactic string together six flights to suborbital space this year. The company was founded by Richard Branson in 2004 to open the experience of spaceflight to everyday people and make some money in the process. Virgin Galactic hasn’t achieved those goals yet, but the company has reason to…

Two NASA probes catch first glimpses of primordial targets
On Aug. 17, the OSIRIS-REx spacecraft obtained the first images of its target asteroid Bennu from a distance of 1.4 million miles (2.2 million km), or almost six times the distance between the Earth and Moon. This cropped set of five images was obtained by the PolyCam camera over the course of an hour for…

New Horizons’ next target might be a binary pair
One artist’s concept of Kuiper Belt object 2014 MU69, the next flyby target for NASA’s New Horizons mission. This binary concept is based on telescope observations made at Patagonia, Argentina, on July 17, 2017, when MU69 passed in front of a star. New Horizons theorize that it could be a single body with a large…

Initial Pluto flyby science results published
STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION This high-resolution image captured by NASA’s New Horizons spacecraft combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). The bright expanse is the western lobe of the “heart,” informally called Sputnik Planum, which has been found to be rich in nitrogen, carbon monoxide…
