SpaceX says they fixed a problem with the helium pressurization system that destroyed a Falcon 9 rocket last year. The company pushes the boundaries of rocket science, creating an occasional jaw-dropping fireball in the process. But will the risk-reward equation change when SpaceX starts flying astronauts?
NASA announced two new asteroid missions today named Lucy and Psyche that will fill important gaps in our understanding of how the solar system was formed. Here are eight things to know about the two missions.

As 2016 came to an end and 2017 rang in, Opportunity was working the first leg of the ascent up the rugged western rim of Endeavour Crater on her way to an ancient gully, the next scientific tour de force down the road, and the mission was closing in on its 13th anniversary of surface operations coming up in the New Year.
What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.
China released a new white paper on its policy and activities in space, outlining ambitious deep space exploration, human spaceflight and space science projects as major priorities for the years up to 2020 and beyond.
In a review of Rogue One: A Star Wars Story, Jason Davis says you're more likely to enjoy the film if you embrace it as comfort food—a story line that fits into a larger sequence of Star Wars events you already know.
Today is the solstice, the longest winter night at Earth's north pole, the longest day of summer in the south. To give a little light to northerners in darkness today, please enjoy this gallery of images of (mostly) sunlit north poles across our solar system.
2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.
Whether you explore The Seth MacFarlane Collection of the Carl Sagan and Ann Druyan Archive online or at the Library of Congress during a visit to Washington, D.C., you’ll learn something new and have a deeper understanding of Carl Sagan.
