Initial Pluto flyby science results published
The first scientific review of data collected during the New Horizons flyby of Pluto describe a small world with a thin but surprisingly complex atmosphere and a variety of surface features, ranging from ancient impact craters to geologically recent glaciers and other structures that reflect widespread resurfacing.
Looking for ET in the waters of Mars and Europa
The discovery of intermittent flows of liquid water on Mars, announced with great fanfare Monday, makes the red planet the leading candidate for the near-term discovery of extraterrestrial life in the form of fossilized microbes or even existing microorganisms, NASA’s chief scientist told lawmakers Tuesday.
NASA confirms intermittent water flows on Mars
Researchers using data from a NASA satellite orbiting Mars said Monday they have found clear evidence of intermittent flows of salty water on the red planet, the first “unambiguous” signs of liquid water on the frigid world and a possible indicator of microbe-friendly environments below the surface.
Soyuz lands safely in Kazakhstan
Three space station crew members — two short timers completing a 10-day flight and a veteran cosmonaut who has logged a world record 879 days aloft over five missions — undocked from the International Space Station and returned to Earth Friday, landing safely on the steppe of Kazakhstan to close out a problem-free flight.
Soyuz takes off with three bound for space station
A Russian Soyuz spacecraft streaked into orbit Wednesday carrying a crew of three on a two-day flight to the International Space Station. Their mission: to deliver a fresh ferry craft to the lab complex that will be needed next March to carry two station crew members back to Earth after nearly a year in orbit.

Astronaut Scott Kelly, 143 days into a planned 341-day stay aboard the International Space Station, urged lawmakers Monday to restore full funding to NASA’s commercial crew program to avoid expected launch delays and continued sole reliance on Russia for transportation to and from the International Space Station.
