Visiting a nuclear missile silo
A fuel line for the Titan missile.
Last week my oldest friend Lloyd and his wife Denise came to visit Diane and I here in Tucson. One of Lloyd’s requests was to visit the Tucson Missile Museum. This museum is built at the site of one of the now disabled missile silos built in the 1960s as a means for launching nuclear weapons against the Soviet Union. Fifty-four silos total had been built and operated, with eighteen of those silos scattered around the Tucson, Arizona area. When the U.S. signed a nuclear arms treaty with the Soviet Union in the 1980s these silos were then shut down and sold. Some became private residences. Others remain buried and abandoned.
One silo, however, was kept as intact as allowed by treaty and made into a museum in order to preserve this artifact of history. Because Diane and I happen to know Chuck Penson, the archivist at the museum, we were able to arrange an augmented tour of the facility. Below are some of my pictures as Chuck took us down into the deepest bowels of the silo.

Grasshopper flies again, but even higher.
The competition heats up: Grasshopper flies again, but even higher.
SpaceX’s Grasshopper doubled its highest leap to date to rise 24 stories or 80.1 meters (262.8 feet) today, hovering for approximately 34 seconds and landing safely using closed loop thrust vector and throttle control. Grasshopper touched down with its most accurate precision thus far on the centermost part of the launch pad. At touchdown, the thrust to weight ratio of the vehicle was greater than one, proving a key landing algorithm for Falcon 9.

The TSA screeners at Newark Airport allowed a federal agent with a fake bomb to pass through security.
Does this make you feel safer? The TSA screeners at Newark Airport allowed a federal agent with a fake bomb to pass through security.
This covert test of security only proves once again how pointless the whole TSA charade is. Get rid of it. If we simply let the pilots and passengers be armed so they can defend themselves, which was the way we did things until the early 1960s, the chances of a repeat of 9/11 will be considerably less, and we would all have considerably more freedom.
Which is what this country is supposed to stand for, y’know.

Dragon has successfully berthed with ISS.
The naysayers will focus on the thruster problems on Friday. The yaysayers will focus on the fix and berthing today. The bottom line, however, is that this mission once again proves that SpaceX is a real player in the space business. Every other company has to match its achievements, most especially in price. The result will be the eventually lowering in the cost to low Earth orbit, which will then make all things possible.
And in fact, we are already seeing this, with the appearance of many new private companies or organizations, proposing all sorts of new space efforts, such as mining asteroids or sending people to Mars. The lower cost allows dreamers to consider their wild new ideas more doable. And they then go ahead and try to do it.

SpaceX has announced that they now have all of Dragon’s thrusters operating and are go for docking with ISS.
They have not announced when the docking will occur, but with the solar panels operating the capsule can function in orbit for a considerable time, giving them breathing room. And time will be necessary as both NASA and the Russians are nervous about letting any spacecraft approach ISS and will want a good number of tests to make sure all is well. The Russians are especially nervous, since they had the unfortunate experience of several collisions when they operated their space station Mir.

Corrupt memory in Curiosity’s A computer system has forced engineers to switch to the rover’s back-up computer.
Corrupt memory in Curiosity’s A computer system has forced engineers to switch to the rover’s back-up computer.
The problem came to light Wednesday morning on Mars when flight controllers at the Jet Propulsion Laboratory in Pasadena, Calif., noticed what appeared to be memory corruption in the computer’s solid-state memory system. The flight software was not recording new data or playing back data already recorded. Instead, it was only sending back real-time telemetry. Later in the day, during a communications session using NASA’s Mars Reconnaissance Orbiter, telemetry from Curiosity indicated the corrupted memory was still present. In addition, Cook said, flight controllers saw the computer had not completed several pre-planned activities.
At that point, the computer was expected to put itself to sleep for an hour or so and then to wake up for a communications session with NASA’s Odyssey orbiter. “It was after that second overflight that we got some more information saying hey, the memory is still corrupted and oh by the way, I didn’t go to sleep when I was supposed to, I stayed awake,” Cook said.
The next communications session came late Wednesday night Earth time, between 10:30 p.m. and midnight at the Jet Propulsion Laboratory. The rover’s computer was still awake and engineers decided to switch over to the B-side system.
The engineers suspect the problem was caused by a cosmic ray hit, and can be fixed by rebooting the computer.

They have not yet released any information about what happened. The link above says that it appears to be related with the communications link, but NASA and SpaceX have as yet released no information other than to say they will hold a press conference in a few hours.
UPDATE: it appears the problem is with Dragon’s thrusters. Engineers have delayed the deployment the capsule’s solar panels while they try to get the thrusters activated. See the second link above.

The Antares hot fire test of the rocket’s first stage was successfully completed tonight.
The competition heats up: The Antares hot fire test of the rocket’s first stage was successfully completed tonight.
The 29-second hot fire test took place at 6:00 p.m. (EST) on February 22, 2013 at the Mid-Atlantic Regional Spaceport’s (MARS) Pad 0A, which was designed and built over the last several years to accommodate liquid-fuel space launch vehicles. The primary goals of the test were to ensure that the launch complex’s fueling systems and the Antares stage one test article functioned properly in a fully operational environment, that engine ignition and shut down commands operated as designed, and that the dual AJ26 first stage engines and their control systems performed to specifications in the twin-engine configuration. The test included a full propellant loading sequence, launch countdown and engine ignition operation. The pad’s high-volume water deluge system flowed throughout the entire period of the test to protect the pad from damage and for noise suppression.
The first stage will now be prepped for a full scale test launch of Antares, expected in about six weeks. If that is successful, Orbital Sciences will then follow with a flight of the Cygnus capsule to ISS.
