Curiosity is out of safe mode and will be resuming full science operations by next week.

Curiosity is out of safe mode and will be resuming full science operations by next week.

It is imperative that the engineers clear up these computer problems now, as communications with the rover will be limited in April because the sun will be in the way.

Transmissions from Earth to the orbiters [Mars Odyssey and Mars Reconnaissance Orbiter] will be suspended while Mars and the sun are two degrees or less apart in the sky, from April 9 to 26, with restricted commanding during additional days before and after. Both orbiters will continue science observations on a reduced basis compared to usual operations. Both will receive and record data from the rovers. Odyssey will continue transmissions Earthward throughout April, although engineers anticipate some data dropouts, and the recorded data will be retransmitted later.

The Mars Reconnaissance Orbiter will go into a record-only mode on April 4. “For the entire conjunction period, we’ll just be storing data on board,” said Deputy Mission Manager Reid Thomas of JPL. He anticipates that the orbiter could have about 40 gigabits of data from its own science instruments and about 12 gigabits of data from Curiosity accumulated for sending to Earth around May 1.

NASA’s Mars Exploration Rover Opportunity is approaching its fifth solar conjunction. Its team will send no commands between April 9 and April 26. The rover will continue science activities using a long-term set of commands to be sent beforehand.

ILS, the company that launches the Russian Proton rocket, has lowered its prices.

The competition heats up: ILS, the company that launches the Russian Proton rocket, has lowered its prices.

The reason they have given is that the insurance rates to use their rocket have risen due to the three Proton rocket failures in the past two years and that they want to offset that cost for their customers. I suspect a second reason is the price pressure that the Falcon 9 is placing on them.

Sarah Brightman’s visit to ISS in doubt.

8:49 am

Sarah Brightman’s visit to ISS in doubt.

Soyuz taxi flights normally visit the International Space Station for a period of about eight days. NASA and Roscosmos are considering extending a 2015 visit to one month, however. If that happens, Brightman would have to give up her seat to a scientific researcher, who would perform some short-term experiments aboard the space station.

Roscosmos manned space flight director Alexei Krasnov had previously indicated that Russia might consider carrying two paying customers on the 2015 taxi flight. So, it would be theoretically possible for Russia to fly Brightman and the researcher. It’s unknown whether Brightman would want to spend that long aboard the space station, however, and pricing policy to longer-duration stays have not been worked out.

Visiting a nuclear missile silo

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.

2:52 pm

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 been successfully berthed with ISS.

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.
