It's looking likelier that there is an undiscovered planet orbiting beyond the Kuiper belt. If it's there, it's roughly 10 times the mass of Earth (or about half the mass of Neptune), likely never gets closer to the Sun than about 100 AU, and takes more than 10,000 years to orbit the Sun.
Late last year, a small team from Honeybee Robotics went to a gypsum quarry to test Planetary Deep Drill, a technology prototype designed to chew tens—and eventually, hundreds—of meters beneath icy planetary surfaces.
In 1972, an attempt to contact extraterrestrial life was cast into space with the launch of the Pioneer 10 spacecraft. What exactly was the message we sent into the cosmos?

The Jason-3 ocean monitoring satellite reached orbit today, but SpaceX's third attempt to land the first stage of its Falcon 9 rocket on a drone ship came up short.
Tomorrow, Cassini will fly by Titan, picking up a gravity assist that will tilt its orbit slightly up and out of the ring plane. That will end what has been a wonderful year of frequent encounters with Saturnian moons.
NASA is adding a miniature space shuttle to its fleet of commercial spacecraft capable of ferrying cargo to the International Space Station.
It's official: China plans to send a lander mission to the lunar farside. A relay satellite will launch to the Earth-Moon L2 point in June of 2018, and a lander will follow at the end of 2018. The landing site may be within the south pole-Aitken basin.

This Friday, astronauts Tim Kopra and Tim Peake will perform a spacewalk to replace a failed power regulator on one of the outermost sections of the International Space Station.
Juno is now fewer than six months and 100 million kilometers away from Jupiter, and the Juno team is busily preparing for the arrival. Amateur astronomers are supporting them by taking lots of Jupiter photos.
SpaceX is set to launch a sea level-monitoring satellite from the California coast this Sunday, while attempting to land the rocket's spent first stage on a floating drone ship in the Pacific Ocean.
In the six weeks since my last detailed Curiosity update, the rover has driven to, on, and around a couple of active barchan sand dunes on Mars. They are now searching for a site to scoop and sample sand on the western edge of Namib dune.

The Division of Planetary Science (DPS) Meeting saw many exciting scientific discussions spanning the range of processes on different planetary bodies, as well as their replication in the laboratory and in models.
One of the great things about NASA is that all the data returned from all of the missions all over the solar system belong to you, the public. NASA shares all these data, and more, through the Planetary Data System, the Minor Planet Center, the Astromaterials Office, and the Astrogeology Science Center.
The used rocket booster SpaceX flown back to Cape Canaveral for an upright landing is undamaged and ready to be test fired, said company CEO Elon Musk.
How many planetary exploration missions are there, and where are they? These days, it's hard to keep track, because there are so many. I plan to begin the new year by taking stock of active missions, figuring out what each has set out to do and accomplished so far, but first I want to step back to consider the spread of missions across the solar system as a whole.
