Last Chance to Participate in the MARS Project

Today is the last day to volunteer as a crew member for The Mars Society's Mars Desert Research Station, a project that has been underway for more than a decade:

In order to help develop key knowledge needed to prepare for human Mars exploration, and to inspire the public by making sensuous the vision of human exploration of Mars, the Mars Society has initiated the Mars Analog Research Station (MARS) project. A global program of Mars exploration operations research, the MARS project will include four Mars base-like habitats located in deserts in the Canadian Arctic, the American southwest, the Australian outback, and Iceland. In these Mars-like environments, we will launch a program of extensive long-duration geology and biology field exploration operations conducted in the same style and under many of the same constraints as they would on the Red Planet. By doing so, we will start the process of learning how to explore on Mars.

Each Station's centerpiece is a cylindrical habitat, "The Hab," an 8-meter diameter, two-deck structure mounted on landing struts. Peripheral external structures, some inflatable, may be appended to the Hab as well.

Each station will serve as a field base to teams of four to six crew members: geologists, astrobiologists, engineers, mechanics, physicians and others, who live for weeks to months at a time in relative isolation in a Mars analog environment. Mars analogs can be defined as locations on Earth where some environmental conditions, geologic features, biological attributes or combinations thereof may approximate in some specific way those thought to be encountered on Mars, either at present or earlier in that planet's history. Studying such sites leads to new insights into the nature and evolution of Mars, the Earth, and life.

It sounds like a great experiment that allows for greater participation in the planning of a future Mars journey.  Go here for the application if you want to be a member of the MARS crew.  Other volunteer opportunities are also available here. 

Note:  Each research team has its own mission patch.


Great Images: Pillar and Jets

More and more I find the beauty of space is more astounding than any artist can imagine here on Earth.  To the right is a fascinating NASA-provided image captured by the Hubble Space Telescope:
  
This Hubble photo is of a small portion of one of the largest-seen star-birth regions in the galaxy, the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula. The pillar is also being pushed apart from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks. 

The much larger image shown below was released in 2007 to celebrate the 17th anniversary of the launch of the Hubble Space Telescope:

...a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth — and death — is taking place. This image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble's Advanced Camera for Surveys. The Hubble images were taken in the light of neutral hydrogen during March and July 2005. Color information was added with data taken in December 2001 and March 2003 at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission. 


If you are trying to locate the Pillars and Jets within the larger image, you can zoom the photo here.  Take a look in the upper right quadrant.

A Second Space Station?

I am not so sure the accomplished very much with our current International Space Station, and yet NASA is now proposing a second station.  This new station, called the "gateway spacecraft," would be located on the far side of the moon at the Earth-Moon Lagrange Point 2, approximately 38,000 miles from the moon and 277,000 miles from Earth.  At this spot the spacecraft would be in an equilibrium between the Earth and moon, thereby requiring little energy to remain in place.  Construction would begin sometime around 2019.

And what would this new station do?  Presumably it will serve as a way-station for trips to the moon and Mars. Now that sounds a little more intriguing than simply circling the Earth, which can be done by any satellite.  Mark K. Matthews in the Orlando Sentinel writes: 

Potential missions include the study of nearby asteroids or dispatching robotic trips to the moon that would gather moon rocks and bring them back to astronauts at the outpost. The outpost also would lay the groundwork for more-ambitious trips to Mars' moons and even Mars itself, about 140 million miles away on average...

It gives purpose to the Orion space capsule and the Space Launch System rocket, which are being developed at a cost of about $3 billion annually. It involves NASA's international partners, as blueprints for the outpost suggest using a Russian-built module and components from Italy. And the outpost would represent a baby step toward NASA's ultimate goal: human footprints on Mars.

This is encouraging, if funding can be located.  What is interesting is that I am seeing very little discussion outside of the Orlando story.  I hope to learn more about this story and this possibility.

Note:  The photo used above is from NASA:

The International Space Station can be seen as a small object in upper left of this image of the moon in the early evening Jan. 4 in the skies over the Houston area flying at an altitude of 390.8 kilometers (242.8 miles). The space station can occasionally be seen in the night sky with the naked eye and a pair of field binoculars.

David Brooks on Elon Musk

Last week's piece by New York Time's David Brooks, Temerity at the Top, was an interesting article on why America needs more Elon Musks.  Brooks holds up Elon Musk as an example of an immigrant who transformed the American economy, and the American dream, through his efforts.

...if growth is ever going to rebound, the U.S. will need a grandiosity rebound and the policies that encourage rich people with brass: immigration policies that attract people like Musk, tax rates that encourage risk and government policies that boost them along (SpaceX has benefited greatly from NASA, and Tesla received a big government loan).

Most of all, there has to be a culture that gives two cheers to grandiosity. Government can influence growth, but it’s people like Musk who create it. Stories like his are worth repeating because maybe some reader will think: What grand transformational process do I want to be a part of? If Musk pinioned his life to the Internet, electric cars and interplanetary travel, what are my projects? 

A BusinessWeek profile cited by Brooks is also worth viewing to learn more about Musk and his projects.  In terms of SpaceX, the author of the profile had this to say about the plant:

One group of workers is assembling the protective casing that will go around a satellite for a potential customer—the governments of both Canada and Thailand are interested, Musk says. Next year, SpaceX looks to launch eight flights, and as many as 16 the following year. If it hits those goals, SpaceX would be handling the majority of the world’s commercial spaceflights. (Companies like Virgin Galactic are offering trips for tourists.) In three years, SpaceX intends to send people to the space station for $20 million each, rather than the $63 million charged today. SpaceX may be Musk’s most solid performer—it already turns a profit as it works through its backlog of orders.
 
I agree with Brooks.  We need both dreamers and solid cooperation between the private sector and the federal government to bring America to the next level.  The private space cowboys are a good place to start.

Another Curiosity Landing Simulation

Just as astronomy has benefited from private citizens scanning the heavens with their own telescopes or offering some of their computer capacity to search for extraterrestrial life, private citizens are now assisting with videos and other media to make the space achievements more dramatic for the public.  I provided one example last month from Andrew Bodrov, and this month we have Bard Canning's painstakingly created "Curiosity Descent" covering Curiosity's landing on the Martian surface.  This video covers events from the heat shield separation all the way to the landing and Curiosity's panning the landscape.  A separate video shows how Mr. Cannin was able to create the video.  It's a fun presentation  And while it is not science, but rather a simulation (I covered NASA's pre-landing simulation earlier), it can only bring greater attention to NASA's amazing adventure.

In an interview, Mr. Canning stated:

My aim with this video was to bring the wonder of the Mars Science Laboratory mission to a wider audience.  To this end, I had to make the video a little more ‘Hollywood’ than its previous incarnations. I expected some backlash for this, but as you can see, the response has been overwhelmingly positive.

Last Word: India Defends Mars Mission


 
Given all the press criticizing India's plan to visit Mars, India's Prime Minister Manmohan Singh defending his nation's decision (as quoted in a recent article in The Times of Oman):

Questions are sometimes asked about whether a poor country like India can afford a space programme and whether the funds spent on space exploration, albeit modest, could be better utilised elsewhere," Singh said in a speech...This misses the point that a nation's state of development is finally a product of its technological prowess.

The statement was made as India successfully launched its 100th space mission placing two foreign commercial satellites into orbit.  Of course, the article then goes on to note that "42 percent of Indian children aged under five are underweight due to malnutrition."

TED Video: Project Orion

If you have a few minutes, you should watch the fascinating video from TED where George Dyson describes Project Orion, a planned mission funded by the United States Air Force (USAF) in the late 1950s and early 1960s.  George's father, Freeman Dyson, was part of the team working on the mission.  NASA wanted nothing to do with it.

As Mr. Dyson explains, this highly classified project was designed to put a man on Saturn, a feat that no one really talked about since given our difficulty in even envisioning a manned trip to Mars.  In the video, Mr. Dyson describes a Marriott hotel-sized, 8 million ton, nuclear-bomb propelled (2,000 to 3,000 bombs required) space craft that would take approximately 8 passengers to a moon of Saturn, possibly Io, Ganymede, Enceladus, Titan, or Mimas.   A larger version was also being planned for Jupiter that could carry a crew of 7 with room for an additional 7 scientists.  


The Orion Project was halted in 1965, most likely in reaction to the new restrictions under the Partial Test Ban Treaty of 1963.  But what  an amazing tale of big ideas, and, I suppose, silly ideas given the planned fuel.  However, Mr. Dyson claims the design may be one of the few off-the-shelf ideas for intercepting a planet killer asteroid, which may be why NASA has purchased some of the material from Mr. Dyson's archives (since NASA misplaced its copies, if they were ever shared with them). 

Mr. Dyson tells more in his 2002 book

The improbable story of the wildest idea-a space craft powered by hydrogen bombs-to come out of the space race.

It was the late 1950s. The Cold War was raging.
Sputnik had made its voyage and the space race was on. In America, it was the age of tail fins and "duck and cover," but it was also a time of big ideas and dreams. On his way to school one day, George Dyson learned of a truly fantastical idea: massive space vehicles that would be powered by explosions of multiple hydrogen bombs. Among the brilliant minds behind this project was George's father, the eminent physicist Freeman Dyson. 

Project Orion chronicles this fascinating episode in U.S. scientific research, while capturing a unique time in American history and culture. The project brought together a cadre of brilliant physicists, the first such assemblage since the Manhattan Project of fifteen years earlier. In an idyllic seaside community in southern California-the very picture of 1950s suburban prosperity-a handful of scientists, tackled a massive project that required the ingenuity of an engineer and the vision of a great theoretician. Their work-ambitious but ultimately futile-took place against the political and cultural backdrop of the Cold War, when nuclear technology spelled both promise and terror.

Dyson's prodigious historical and scientific research, combined with his personal reminiscences and connections, make for a lively, richly detailed narrative.

Three cheers for big ideas, and we can only hope that other highly classified projects are thinking long term about space exploration.  Of course, I would prefer a more open debate with the involvement of NASA rather than some military-only application.  However, as I noted earlier, the USAF seems to prefer its own parallel space program.
