Dawn has begun its slow departure from Vesta in anticipation of its journey to the solar system’s largest asteroid, Ceres.

The departure was actually announced two weeks ago, but since this is a very slow process it isn’t like we have missed anything. Dawn’s ion engines are very efficient, but they work at a very leisurely pace. It will take a month for the engine’s thrusters to push Dawn out of its orbit around Vesta.

The leading team in the Google Lunar X-Price contest last week successfully tested by remote control the astronomical telescope they intend to include with their lunar lander.

[The Google Lunar X Prize] requires the participants to successfully land a lunar rover on the surface, drive it a minimum of 500 meters (about a third of a mile), and send back high definition video and imagery. Moon Express intends to land this first lunar lander near the Moon’s equator.

Moon Express is planning to send its first robotic lander to the Moon in late 2014. It will be launched atop either SpaceX’s Falcon 9 rocket or another commercial launch vehicle. It intends to fly ILOA’s shoebox-sized test telescope, called ILO-X, as part of its [X prize] entry. There are additional prizes available which might be won by an educational lunar telescope, such US$1 million prize for the entry which adds the most to diversity within space studies.

A Russian Proton rocket has failed to put two satellites into their proper orbit.

A Russian Proton rocket has failed to put two satellites into their proper orbit.

This failure of one of Russia’s more reliable rockets comes at a very bad time, as the competition with SpaceX and other competitors for commercial launches is right now heating up. As the article notes,

Moscow, which carries out 40 percent of global space launches, is struggling to restore confidence in its industry after a string of mishaps last year, including the failure of a mission to return samples from the Martian moon Phobos and the loss of a $265-million communications satellite. …

“The last failures to a certain extent undermine Russia’s position as a country that provides space launch services,” said industry expert Yuri Karash, a member of the Russian Academy of Cosmonautics.

Such mistakes strengthen Russia’s competitors, such as Europe’s Arian rockets, Karash said, describing Russia’s space industry, struggling to recover after a generation of brain drain and crimped budgets, as “not in the best condition by a long shot.”

The new Mars rover…

8:54 am

Tonight at 10:30 pm (Pacific), the new Martian rover Curiosity will hopefully touch down safely on the Martian surface to begin several years of research in the crater Gale.

What has been most amazing to me is the amount of interest in this landing by the press, especially the mainstream press. Normally these outlets don’t care that much for space exploration, a trend that began after the Apollo 11 landing in 1969 when it became trendy in liberal circles to down play space exploration so that “the money could instead be spent solving our problems here on Earth.”

Today, however, I count more than forty news articles on this upcoming landing, most of which come from mainstream sources. It seems that these outlets have finally discovered something that has been obvious from the beginning: the American public is fascinated with space exploration, and if you want to attract readers, it is better to provide coverage of what interests them rather than push a political agenda that few agree with.

Anyway, if you want to follow the landing live, go here for a full outline of options. Or go directly to NASA TV. Most of what you will see will the control room at JPL, with many engineers staring at computer screens waiting to find out if the landing was a success, about twenty minutes after it took place. This is because it will take that long for the communications signals to travel from Mars to the Earth. Essentially, Curiosity is on its own in this landing.

More signs that the Voyager 1 spacecraft is about to enter interstellar space.

More signs that the Voyager 1 spacecraft is about to enter interstellar space.

For the last seven years, Voyager 1 has been exploring the outer layer of the bubble of charged particles the sun blows around itself. In one day, on July 28, data from Voyager 1’s cosmic ray instrument showed the level of high-energy cosmic rays originating from outside our solar system jumped by five percent. During the last half of that same day, the level of lower-energy particles originating from inside our solar system dropped by half. However, in three days, the levels had recovered to near their previous levels.

A third key sign is the direction of the magnetic field, and scientists are eagerly analyzing the data to see whether that has, indeed, changed direction. Scientists expect that all three of these signs will have changed when Voyager 1 has crossed into interstellar space. A preliminary analysis of the latest magnetic field data is expected to be available in the next month.

Based on this report, expect scientists to announce that Voyager 1 has left the solar system sometime before the end of the year.

Alan Boyle at NBC tonight reports that Boeing, SpaceX, and Sierra Nevada are the winning companies in the competition to provide human ferrying services to ISS.

Alan Boyle at NBC tonight reports that Boeing, SpaceX, and Sierra Nevada are the winning companies in the competition to provide human ferrying services to ISS, to be announced officially by NASA tomorrow.

The report does not provide dollar numbers. This Wall Street Journal story says that Boeing and SpaceX will be the prime contractors, which suggests that Sierra Nevada will be getting a smaller award.

New analysis of Lunar Reconnaissance Orbiter images suggests that most of the American flags planted at the Apollo landing sites are still standing.

New analysis of Lunar Reconnaissance Orbiter images appears to prove that most of the American flags planted at the Apollo landing sites are still standing.

Sadly, the analysis also seems to prove what Buzz Aldrin reported, that the Apollo 11 American flag was blown over by the exhaust from the ascent stage when the astronauts took off.

I wonder if anyone from the United States will ever have a chance to pick it up?
