“Mars Rover Marks an Unexpected Anniversary With a Mysterious Discovery”
Chang, Kenneth. "Mars Rover Marks an Unexpected Anniversary With a Mysterious Discovery." Nytimes.com. New York TImes, 23 Jan. 2014. Web. 9 Feb. 2014. <http://www.nytimes.com/2014/01/24/science/space/mars-rover-marks-an-unexpected-anniversary-with-a-mysterious-discovery.html?ref=space&_r=0>.
On January 23, NASA celebrated the astounding 10th anniversary of the Opportunity Mars rover. The fact that it is still even functional today is a shock to all, for it was built to only last three months. Scientists predicted that after this time, too much dust would have accumulated on the solar panels and the batteries would die. But thankfully, the planet’s strong winds have been able to blow away this dust, leaving Opportunity able to operate. Not only is it just operating: A few weeks ago, it discovered a rock that wasn’t in the same location just two weeks prior. Most researchers attribute this seemingly spontaneous materialization to the rover’s lame wheel accidentally flicking it out of the ground, but what’s more interesting is the rock’s composition. It’s high in sulfur, magnesium, and manganese, and appears white on the outside and red on the inside. This is unusual, considering Mars’ crust is made of basalt and iron oxide. Scientists are unsure how it got there, but toy with the idea that the rock could be a vestige from an asteroid hit. Dr. Squyres, principal investigator of Opportunity, accurately describes the rover as telling “an ongoing story of discovery” of Mars. Each new development opens up more and more questions pertaining to the mysterious red planet, such as the rover’s recent find of a clay mineral known as iron smectite. To most this may seem insignificant, but geologists know this mineral only forms in environments with water, giving us a taste of a much different Mars thousands of years ago. The Opportunity rover has miraculously driven almost 24 miles further than was predicted, and the 170,000 pictures it has taken is a gift to scientists everywhere. But considering it can only fight off Mars’ conditions for so long, and as the project currently costs 14 million dollars each year to finance, it’s quite possible that this anniversary is the rover’s last.
Mars, Opportunity, and its discoveries are relevant to not just serious scientists and researchers, but to the general public as well. If the rover does indeed find signs of life on Mars, that means there could be a whole other species for humans to communicate with. Not only that, but we could work to colonize on Mars if we knew it was habitable. Knowledge of other life systems other than ours would forever change life as we know it; we would no longer be alone in our solar system. And second, NASA, like all other government projects, is funded by the US government, ergo paid for by taxpayers. The population has to decide whether or not they want their money going toward the Opportunity project, or something else entirely. To make this decision, we need to know what kind of findings the rover is bringing to the scientific realm, and weigh the pros with the economic cons. Either way, knowledge of Mars’ developments is more than relevant to the human race.
Although the article was interesting and informative, it could also be very confusing at times. The author jumped around from topic to topic in a nonsensical way, making it hard to follow. There were few transitions between ideas, leaving the reading wondering how, if at all, the thoughts are connected. Plus, as the author was obviously well versed in astronomy, he sometimes left out key facts about Mars, probably assuming it was part of the reader’s prior knowledge. This was not always the case, most notably when the author discussed the rock’s chemical composition. Even though he said the rock’s composition and noted it as “unusual”, he took no steps as to explaining why. I had to research the composition of Mars on my own to understand why the presence of sulfur, magnesium, and manganese caused such a shock. Despite these shortcomings, the introduction’s distinct clarity gave the reader a strong foundation before reading the details, so the reader could infer most of the missing information moving forward. The picture was also very assistive in visualizing the situation as scientists would see directly from Opportunity’s photographs. Overall, I thoroughly enjoyed reading this article, for I’m very interested in the realm of outer space, but wish it was structured in a more comprehensible way.
