A Russian Bion-M spacecraft, filled with mice, lizards and other animals, returned to Earth after 30 days in space with about half its mice and all its gerbils dead.
The Bion-M experiment, launched from Baikonur, Kazakhstan, on April 19, carried 45 mice, 15 geckos, 18 Mongolian gerbils, 20 snails and a number of different plants, seeds and microorganisms, according to a Russian state news site. About half of the mice died, but the lizards reportedly survived. The Mongolian gerbils all expired, apparently due to an equipment failure, said Vladimir Sychev of the Russian Academy of Sciences, according to AFP.
It is unclear at this moment whether it was the harsh environment of weightlessness or equipment failure that caused the mortalities.

This very nicely written article describing the scientific goals of AMS is even better in that it emphasizes strongly the uncertainties of the data and the theories behind it.

The Mars rover Opportunity has now traveled farther than any other American rover, including the Apollo 17 rover on the Moon.
The Mars rover Opportunity has now traveled farther than any other American rover, including the Apollo 17 rover on the Moon.
The team operating NASA’s Mars Exploration Rover Opportunity received confirmation in a transmission from Mars today that the rover drove 263 feet (80 meters) on Thursday, bringing Opportunity’s total odometry since landing on Mars in January 2004 to 22.220 statute miles (35.760 kilometers). … The international record for driving distance on another world is still held by the Soviet Union’s remote-controlled Lunokhod 2 rover, which traveled 23 miles (37 kilometers) on the surface of Earth’s moon in 1973.
We have to once again remind ourselves that the roving part of Opportunity’s mission was originally only supposed to last 90 days, not 9 years.
The Kepler mission has lost its second gyroscope, ending the ability of the telescope to aim precisely.

The telescope’s primary mission, to stare continuously at one section of sky, looking for exoplanet transits, is over, though it might still be re-purposed for other astronomical research.

Russia’s Proton rocket successfully put a commercial communications satellite in geosynchronous orbit on Wednesday
The competition heats up: Russia’s Proton rocket successfully put a commercial communications satellite in geosynchronous orbit on Wednesday.
This is the third successful Proton launch this year and the third since a December launch failure. It appears the Russians have ironed out the kinks in the Briz-M upper stage, and are ready to compete with SpaceX’s Falcon 9 rocket. In fact, at the moment they are the only ones who can compete with the Falcon 9, at least when it comes to price.

SpaceX is about to finalize a deal with the Air Force to launch satellites on both its Falcon 9 and Falcon Heavy rockets.
SpaceX is about to finalize a deal with the Air Force to launch satellites on both its Falcon 9 and Falcon Heavy rockets.
For the Dscovr mission, scheduled for late 2014, a Falcon 9 will be used to launch an Earth and space weather satellite to the Sun-Earth Lagrange point L1, a location approximately 930,000 mi. from Earth. The Dscovr program, which will provide warning of space weather events, is a joint effort between the Air Force, NASA and the National Oceanic and Atmospheric Administration. The STP-2 mission, which is targeted for launch on a Falcon Heavy in mid-2015, includes two space vehicles: the Constellation Observing System for Meteorology, Ionosphere and Climate-2 (Cosmic-2), designed to monitor climate behaviors; and the Demonstration and Science Experiments (DSX), which will conduct radiation research. [emphasis mine]
The big story here is that even before it has flown the Falcon Heavy once SpaceX already has a customer for it.
