A SpaceX Falcon 9 rocket booster recovered by a drone ship last year will be reflown later this week, marking what could be a new milestone in the quest for affordable spaceflight.
There's no verdict quite yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.
For nearly two years, Opportunity's world has been tilted 10–25 degrees as it drove down to the lower slopes of the wall of Endeavour Crater. Toward the end of last week, Opportunity pulled itself up and over the lip of the crater.
This week MAVEN had to execute a short rocket burn in order to prevent a future collision with Phobos. Curiosity (and other rovers) may have played a role in those trajectory predictions.
Driving the Mars Exploration Rovers (MER) mission further into its fourteenth year of surface operations, Opportunity continued hiking the slopes of Cape Tribulation in February and finally reached the crest of Endeavour Crater’s western rim.

Opportunity has successfully clawed its way to within a few meters of the crater rim after spending the last few months climbing and the last two years inside the crater.

Several sols ago, Opportunity made it up and past the steepest section of its climb out of Endeavour crater.
2017 got off to a start that was unprecedented in every good way: Opportunity completed her 13th Earth year of surface operations and drove the first overland expedition of the Red Planet into its 14th year.

Since my last update, the Curiosity mission has developed a better understanding of the problem that prevented them from drilling at Precipice, but its intermittent nature has slowed the development of a workable solution that will allow them to use the drill again. In the meantime, the rover has driven onward, making good use of its other instruments.
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.
More than a month after a Progress spacecraft bound for the International Space Station plunged to the ground during a botched launch attempt, investigators are still unable to clear its rocket to carry future ISS crews.

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.
Our preview of spaceflight in 2017 starts with highlights of missions and events happening on and around our home planet.

Opportunity continues to climb up the inner crater wall of Endeavour crater, heading south on its journey toward its next valley target.
