CAPE CANAVERAL AIR FORCE STATION, FL – The sudden and unexpected outage of a crucial tracking radar that is mandatory to insure public safety, has forced the scrub of a pair of launches planned for this week from Cape Canaveral, FL, that are vital to US National Security, United Launch Alliance, SpaceX and NASA.

The tracking radar is an absolutely essential asset for the Eastern Range that oversees all launches from Cape Canaveral Air Force Station and the Kennedy Space Center on the Florida Space Coast.
The pair of liftoffs for the National Reconnaissance Office (NRO) and SpaceX/NASA had been slated just days apart on March 25 and March 30. [click to continue…]

Little Philae is awake! ESA sent a wake-up call to the 100-kg (220-lb) lander riding aboard the Rosetta spacecraft this morning at 06:00 GMT, bringing it out of its nearly 33-month-long slumber and beginning its preparation for its upcoming (and historic) landing on the surface of a comet in November.

Opportunity Rover Gets Power Boost from Wind Events on Mars

The Opportunity rover on Mars has gotten a 70% boost in power over the past few weeks. A good portion of that comes from the fact that its springtime in Mars’ southern hemisphere where Oppy now sits along the western rim of Endeavour Crater and so the Sun is now shining longer and higher in the sky. But also, several recent gusts of wind – or perhaps small dust devils – have cleaned much of the dust off the rover’s solar panels.
The rover team reported that between Sols 3605 and 3606 (March 15 and March 16, 2014), there was a dust cleaning event that resulted in about a 10% improvement in power production to 574 watt-hours, and then another cleaning event this week has put the power output to 615 watt-hours.
See a self-portrait that Opportunity took of its solar panels back in January to compare with the image above of how much cleaner the solar panels are now.
