The Kepler mission has lost its second gyroscope, ending the ability of the telescope to aim precisely. More details here.
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.
The competition heats up: Richard Branson recently told an audience in Dubai that the first commercial flight of SpaceShipTwo will occur before the end of 2013, and that commercial flights from Dubai will occur two years later.
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.
Three astronauts safely returned from ISS today.
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.
The engineering test prototype of Dream Chaser has been shipped to California for drop tests this summer.
Checking the cracks on the first Orion capsule to fly.
In replacing a pump during Saturday’s spacewalk it appears the astronauts have fixed the coolant leak.
The astronauts will replace a pump tomorrow on their spacewalk in the hope this will fix the leak in ISS’s solar panel cooling system.
The spacewalk has still not been approved, though it seems likely it will happen.
Update: As of this morning the spacewalk has been approved, set to begin at 8:15 am (Eastern).
A high energy laser beam destroys a rocket from a distance of a little less than a mile.
Reagan was right: His proposed SDI laser-based defense system was a reasonable proposal, despite the ridicule of the leftwing elites in the 1980s. I have posted the video of this test below the fold.

Astronauts today spotted an ammonia coolant leak in ISS’s left-side power truss.
They are monitoring it, but have so far not made any decision about what to do about it, if anything.
This problem is a perfect illustration of why a flight to Mars is more complicated in terms of engineering than first appears. We might at this time be able to build that interplanetary spaceship (with the emphasis on the word “might”) but could its passengers maintain it millions of miles from Earth? Right now I’d say no. We need to learn how to build an easily repaired and self-sufficient spaceship. ISS is neither. It is also not a very good platform for testing this kind of engineering.
Update: The astronauts on ISS are preparing for a possible spacewalk on Saturday to deal with the problem. More details here.
The International Space Station has switched all its computers from Windows to Linux.
I love this quote:
“We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable.”
I’ve been on Linux for almost six years, It crashes, but that is usually user error.
