In replacing a pump during Saturday’s spacewalk it appears the astronauts have fixed the coolant leak.
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).
In a science fair project that came in third, a fourteen year old has discovered that the magnets inside IPADs can interfere with heart devices like implanted defibrillators.

A high energy laser beam destroys a rocket from a distance of a little less than a mile.
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.
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.
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.

He gets it. This was the same problem the Russians discovered when they were operating Mir.
SpaceX is moving its Grasshopper test program to New Mexico’s spaceport.
SpaceX is moving its Grasshopper test program to New Mexico’s spaceport.
The move confirms big plans for the test bed. Flights to date have been conducted at SpaceX’s engine test site in McGregor, Texas. SpaceX received a waiver from the FAA to fly Grasshopper up to 11,500ft from McGregor, but Spaceport America is an FAA-certified spaceport where no where no waivers are required. “Spaceport America offers us the physical and regulatory landscape needed to complete the next phase of Grasshopper testing,” says SpaceX president Gwynne Shotwell.
Japan’s entire space program faces a major overhaul.
Feeling the heat of competition: Japan’s entire space program faces a major overhaul.
In the last few decades Japan has not done very well in space when compared to other Asian countries like China and India. Thus, this overhaul. Yet, based on this article, it doesn’t seem to me that they are making the real changes they need to do to successfully compete. If anything, it sounds instead like the actions of a bureaucracy that is merely rearranging the deck chairs on a sinking ship, in the hope that this will somehow save it.
North Korea has withdrawn two missiles from their launch site.
Good news: North Korea has withdrawn two missiles from their launch site.
The article is very vague, unfortunately, about the rockets themselves and whether either were the orbital rockets that North Korea had been threatening to launch several weeks ago.
Europe’s new Vega rocket made its second successful commercial launch today, placing three satellites in orbit.
