The new Mars rover…

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?

Russia has announced it has begun construction on a lunar lander, set for its first unmanned test flight in 2015.

The competition heats up: Russia has announced it has begun construction on a manned lunar lander, set for its first unmanned test flight in 2015.

There have been many such announcements from Russia over the past decade with few ever coming true, since such announcements are generally nothing more than a public relations lobbying effort to get funding.

The most intriguing part of this article however was this quote:

Last week, head of the Lavochkin Scientific and Production Corp. Victor Khartov said Russia must “return to the Moon in 2015 in a Soviet style, to prove everyone and ourselves that we remember all the Soviet Union could do” at the Farnborough air show in Britain.

I would interpret this statement as a desire for Russia to compete more aggressively with the U.S. and others, as they did back in the days of the Soviet Union. It was also in that time period that the Lavochkin center was in its heyday, with lots of money and research work.

Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.

Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.

The long travel time was designed to save fuel at launch — thus increasing payload — by allowing orbital mechanics to bring the capsule and station together. I wonder then why the Russians are considering this change. Have the figured out a way to save the fuel in other ways?

The cost of launch

Two news items from NASA today:

What I find most interesting about these stories is the fees charged by the two companies. SpaceX will be paid $82 million for its one launch, while ULA will be paid $412 million for its three launches, or about $137 million per launch.
