NASA’s STEREO Mission
The languishly manned spaceflight programs of the world are attracting less and less funding, as well as a rapidly shrinking public presence. Even the most ardent supporters balk at the extravagant launch costs and fragile safety margins endemic to human endeavors in space. However, riding the coattails of these costly missions for decades have been an extensive series of unmanned missions that operate at a fraction of these costs, with vastly differentiated mission times involved. NASA and the ESA quietly landed on Titan (largely to public chagrin and apathy) in 2005, and this 13-year mission has cost a grand total of $3.2 billion, spread across NASA and its European counterparts. In contrast, each near-Earth space shuttle mission is estimated to cost $1.5 billion, and a total of $170 billion has been spent on the shuttle alone.
The STEREO mission consists of two identical probes launched simultaneously on a modified Air Force Delta II rocket in late October 2006. STEREO A and B were placed into very elliptical orbits, and NASA utilized a gravitational slingshot via the moon to place them for operations. The STEREO mission is so-termed for the orbiters’ dual observations in their final heliocentric orbit. The crux of this mission was the utilization of what astrophysics knows as La Grange points – points in space where the gravitational interaction between a two bodies is negated and an object can remain in a simple, stable orbit for long periods of time. Every pair of sun-planet interactions has five La Grange points: L1 is between the body and the sun; L2 is on the opposite side of the orbiting bodies at a precise point. Point L3 is a highly unstable region precisely 180 degrees across from Earth, in our orbital wake – an “anti-Earth” which is perpetually shrouded from our view by the sun. STEREO A and B (“Ahead” and “Behind”) were placed at La Grange points L4 and L5 – the most stable of these gravitationally-canceled regions – which lead and follow along Earth’s orbital path.
STEREO’s simplest mission descriptor is stereoscopic imagery of the Sun in ways we are obviously incapable of when stranded Earth-side. Of particular interest to researchers is the detection and study of the sun’s intermittent Coronal Mass Ejections (discussed on pages 10 and 11). For science nerds, the mission allows for some very interesting optical trickery via false-3D animated .gifs of the sun’s rotation and long, high-resolution video of our star spewing untold billions of tons of matter into the solar system. Each spacecraft carries a wealth of instruments for measuring the many parameters of the sun’s daily operations.
Among the instruments on board each spacecraft are instruments measuring the full electromagnetic spectrum, as well as heavier particles and safe distance measurement of the large plasma masses produced in the large thermonuclear reactor. This instrumentation has now come online in full, as each orbit realigns and the spacecrafts move further away from each other. In January 2009, STEREO A and B reached 90 degrees relative to each other – a landmark that scientists say will greatly improve the orbiters’ data triangulation capabilities. It is estimated that the mission will reach a full 180 degrees from each other in 2011, and this will represent the first time that the entire sun will be visible to humanity at one time. The mission has the possibility to be extended to 2015 and beyond, and like other unmanned probe missions, this would be more time than the project was optimistically budgeted. The burgeoning data emerging from STEREO, its unique mission, and its low cost at $550 million (roughly a third of a shuttle mission) will build more goodwill for NASA. Although popular culture almost exclusively cites manned space accomplishments as milestones, unmanned missions like STEREO will continue to effectively provide a provocative scientific background for decades to come.


Currently, the Soudan facility has two experiments in progress. The old husks of the Soudan 1 and 2 detectors were cleared to make way for the CDMS-II experiment. CDMS stands for Cryogenic Dark Matter Search – an effort begun at Stanford University and moved to Soudan in 2003. In this experiment, incredibly delicate detector plates composed of germanium and silicon lattices are super-cooled to temperatures within fractions of Absolute Zero, and thus are very physically static. The detectors are monitored for disturbances, however minor. The goal is to detect what are known as Weakly Interacting Massive Particles (WIMPs) and ultimately tangential confirmation of the existence of dark matter. Because WIMPs only interact with each other via the weak nuclear force and gravity itself, the absolute pristine conditioning of monitoring devices is critical to the experiment’s success. The CDMS experiments have been central to a global effort in researching dark matter and chipping away at one of the most fundamental problems confronting physics today.
In the international space community, there is no quest that plagues mankind more than the search for extraterrestrial life. Driven both by necessity and curiosity, a discovery of an environment hospitable to even the most primitive form of life in Earth’s own backyard would strengthen the argument that there are likely tens of hundreds of solar systems in the universe that harbor the same potential. 
Ranging from assisted suicide to genetically altered food to psychosurgery, the field of bioethics is diverse and of great importance. Every day people grapple with the moral struggles modern science has presented us with. In America, we value our beliefs like we value our identities.
It may have been inconceivable in decades past that the end of Pax Americana would come so soon. Oh, there were movies, of course. Little tongue-in-cheek nods to what we smuggly, privately “knew”: that our age was different. The world had reached a new epoch of development. This time around we would stave off the pitfalls that have dampened economic “progress” in the past. The new, everexpanding network of producers and consumers would expand, without bound, providing jobs to all of the disenfranchised third world and bringing developed nations more wealth than had ever been accrued before. Faux-pastoral suburban sprawl dominated the landscape and quickly became the default environment for Americans. Credit was abundant, terms were good and everyone was happy.
In our postmodern society, it will be particularly interesting to see how the media covers the idea of widespread homelessness and poverty. Whether the “economic crisis” has been exacerbated or introduced by the media is a topic for a billion other self-righteous college opinion columns. However, there should be serious concerns about whether the current generations can even process the idea of real scarcity. In addition, media coverage will likely reach a new equilibrium in substituting bread and circuses for substantive discourse. After all, there are only so many dodgy euphemisms and simplistic graphic work one can endure before the reality of resource destitution comes crashing down.
