A Martian eclipse

The hubbub about this week’s lunar solstice eclipse was, from my perspective, mostly manufactured press blather. For those who had never seen a lunar eclipse, it was a spectacular experience, but there really was nothing scientifically or technically unique about the fact that it happened to occur on the solstice.

However, below is an eclipse that is definitely unique both technically and scientifically. Scientists using the Mars rover Opportunity have filmed an eclipse on Mars, showing the Martian moon Phobos crossing in front of the Sun. Consider the engineering accomplishment: not only did they need to be able to calculate exactly when this would happen at a very particular spot on the Martian surface, they had to have a camera there able to take the movie. And they had to operate it from Earth!

Electricity from wind plant so expensive no one will buy it

The electricity produced from a proposed wind plant will be so expensive the company can’t find customers. They do have one customer, however, but one wonders why:

In its 15-year deal, National Grid agreed to pay 18.7 cents per kilowatt hour for Cape Wind power beginning in 2013, with a 3.5 percent annual increase. The starting price is twice what National Grid pays today for power from fossil fuels, and regulators say the contract will add about 1.7 percent to its residential customers’ bills.

Read the whole article. It explains a lot about the failures of renewable energy, and how the efforts of the government and environmentalists to force it on us is misguided and downright foolish.

A team of explorers and scientists have today completed the first there-and-back crossing of Antarctica in wheeled vehicles.

A 10-man team of explorers and scientists today completed the first there-and-back crossing of the continent of Antarctica using wheeled vehicles. From the expedition blog:

We quickly took ourselves to the mess tent for some hot coffee and something which we had been craving for a while – Coca Cola. The feeling among the team was satisfaction and elation at what we had achieved and relief that the belt drive had held out! The first Expedition ever to travel coast to coast and back again, with the privilege of visiting the South Pole twice. We joked in the mess tent before deciding that we were not going to sleep and headed over to the Mechanic Area and back to the vehicles.

More evidence that the rim of Shackleton crater is valuable real estate

The image below was produced by Lunar Reconnaissance Orbiter by assembling data from numerous images over six months. The levels of brightness and darkness indicate the percentage of time in which an area is sunlight. The red dot just below the rim of Shackleton shows the approximate location of the south pole.

As you can see, the rim of Shackleton Crater nearest the south pole is illuminated by the sun most of the time, while the nearby crater floor never gets sunlight. This data confirms what Japanese scientists found using their lunar probe, Kaguya. The south pole has the ideal combination of locations with nearly continuous bright sunlight (to provide power) and nearly continuous darkness (where explorers will likely find significant amounts of frozen water), making this is an excellent location to build that first lunar base. And from the image you can see that the Shackleton Crater rim is not the only spot near the south pole with these conditions.

Also, if you look at the close-up image of Shackleton’s rim that I posted here, you will see that there is plenty of room to land and set up residence.

The flight of Falcon 9/Dragon: Doing it right

For those that want to relive the experience of success, SpaceX has posted a short highlight video of last week’s successful test flight of Falcon 9/Dragon capsule.

It is difficult to overstate the importance or magnifience of this achievement, accomplished not by a government but by a private company. As SpaceX rightly brags on its website:

This marks the first time a commercial company has successfully recovered a spacecraft reentering from Earth orbit. It is a feat previously performed by only six nations or government agencies: the United States, Russia, China, Japan, India, and the European Space Agency.

What I find even more telling is how quickly SpaceX got this done. The first launch attempt of their first rocket, Falcon 1, took place in March of 2006. About that same time they began work on Falcon 9, and were able to successfully fly its first mission only four years later. Contrast that with NASA. President Bush proposed building a replacement for the shuttle in 2004, and six years later all NASA could do was fly a mockup of Ares I/Orion, not the actual article. And that leaves out NASA’S numerous previous attempts to build a shuttle replacement that spent billions, and never did more than produce pretty powerpoint presentations.

SpaceX’s speed of operation (a sure sign of efficiency) is reminiscent of the early days of the space age. Then, NASA might have laid out the overall plan, but everything was built by private companies, all used to fighting for profits and market share. None could afford a leisurely pace, nor could they afford to do things badly. If they did either, their business would suffer. As a result, the United States was able to go from having no ability to put anything in orbit to putting its first man in space in less than three years, and was able to follow that up with the first manned lunar mission only seven years later.

Air Force agrees to Share data on the Meteorites its surveillance satellites detect

The Air Force has agreed to share the meteorite data its surveillance satellites detect.

Though the article above makes it sound like this data includes a lot of Earth-destroying asteriods, almost all of these detections are of smaller rocks burning up in the atmosphere, information researchers need to produce a more complete census of the solar system.

The greed for power, or why it is always better to do without government help

In an article today on spaceref.com “NASA: It’s Our Space Station – Not Yours,” Keith Cowing has some harsh words for NASA and its management of the research on ISS. Based on what he witnessed at a NASA meeting, it appears that NASA wants to retain control over all research on the space station, while denying access to outside other researchers. Key quote:

In addition to prohibiting the ISS National Laboratory contractor from getting its hands on human-based research, Mark Uhran also stated that any proposal that proposed to do anything with spacecraft systems or engineering would be similarly deemed non-responsive. In other words two of the most interesting things you can do on the ISS – the sorts of thing you’d want a larger research base to focus on (assuming you are really interested in outside participation) are off limits due to executive fiat.

Where is NASA’s justification for limiting the ability of the private and educational sectors from making full utilization of the amazing capabilities that are offered by the ISS? Answer: NASA made it up. Truth be known, NASA was dragged kicking and screaming into supporting this National Laboratory concept. Congress had to enact a law to make them do it.

None of this surprises me. NASA is a government agency, and as a government agency it is going to protect its turf, come hell or high water. It is for this reason I think it a bad idea for the new space rocket companies to take any NASA money, up front. If they do, NASA will immediately use those funds as a club to force these new companies to do things as NASA wishes, rather than being free to compete and innovate on their own. In other words, NASA will use the funds to maintain control of all space exploration.

Better the new companies build their rockets and spaceships on their own, and then sell these new inventions to NASA or whoever else wants to use them. Let the profits pay for the work, not the needs and regulations of a government agency.

Not only will this free competiton produce a lot more creativity and innovation, it will almost certainly help to reduce the cost of space travel, as these companies fight to gain market share. And most importantly, it will frame the future exploration of space in the context of freedom rather that a state-run endeavor.

And isn’t freedom the principle that the United States of America stands for?

Boeing Submits Proposal for 2nd Round of NASA Commercial Crew Development Program

In competition with the Orbital/Virgin Galactic proposal I mentioned yesterday, Boeing has submitted its own proposal to provide crew and cargo ferrying service to ISS.

Considering the federal budget debt and the political winds for reducing that debt, I have great doubts the subsidies for these proposals will ever arrive. Nonetheless, with the end of the shuttle program and nothing to replace it, the United States has a serious need for a system to get crew and cargo into space. And in a free society, fulfilling that need means profits, which is why these proposals are beginning to appear, and will get built, regardless of whether Congress funds them up front or later buys the services.

Orbital Sciences and Virgin Galactic team up to propose orbital craft

Orbital Sciences and Virgin Galactic have teamed up to propose a four person reusable orbital spacecraft to ferry crews to ISS. Key quote:

The spacecraft, designed to launch atop an Atlas 5 rocket and dock with the international space station, could be ready for test flights as early as 2014. The remotely piloted spacecraft would be able to carry four passengers initially, including three astronauts and one paying ticketholder, though based on market demand the number of private rides aboard the vehicle could grow to two, with four astronaut seats available, sources said. In the works at Orbital for the past year, the reusable spacecraft would be built using existing materials and technologies, employ standard hypergolic propellants and rely on a pusher escape system in the event of a launch mishap, sources said. [emphasis mine]

Note their insistence that they be allowed to fly tourists. This is a major change from how NASA has operated in the past, as a Soviet-style government agency hostile to commercial profits.

Correction: Clark Lindsey notes that the Orbital press release makes no mention of Virgin Galactic, as reported above.
