Essay --
The ability to detect remote sensing has made great strides over the past few decades. Mars has been a major center of speculation and inquisition during these studies. By using Remote sensing, scientists are able to view, analyze, hypothesis, and gain better understanding of what can be detected on and under the surface of Mars. In 2006 Baldassare Bartolo published work that suggested that remote sensing is the act of gaining information about an object/phenomenon without making any actual physical contact. Remote sensing is most commonly used with aerial sensor technologies in order to detect and classify the objects on Earth via signals (electromagnetic radiation emitted from aircraft and/or satellites) (Bartolo 2006). The process of how the remote sensing works has been modified and improved over the past few years into what we use today on earth as well as on the various Mars exploration missions. Remote sensing works with energy. Scientists have found that remote sensing works because all objects on the earth emit an electromagnetic energy (Chee, 2008). The energy includes a visible light and other radiations in the electromagnetic spectrum (Bartolo 2006, Anderson 2013). The portion of the spectrum that is visible to the human eye is tightly limited to wavelengths in the 0.4 micrometre (ââ¬Å"blueâ⬠) to 0.7 micrometre (ââ¬Å"redâ⬠) range. Just past the red end of the spectrum is the infrared region and itââ¬â¢s subdivisions that are reflected by the earth's surface, and thermal infrared given by the objects (Plaza et al. 2009). Researchers have been able to develop different sensors and cameras that are able to detect and record the energy being transmitted from earths surface. These cameras and sensors on satellites relay th... ...ut the researchers hypothesis states that the small amount of hydrogen is likely to be more chemically bound to the minerals in the soil, than in the form of water ice (Dartnell 2013, Ezell 2004). Therefore, with having water ice at the poles and water in the surface rocks, it is far more likely for the various carved channels to be formed from a liquid than that of lava (granted there are lava channels as well.) By observing images, researchers are able to speculate how the channels formed by simply comparing it to the conditions on earth. Water erodes away sediment and leaves specific clues to look for. Researchers will continue unveiling what is on and under the Red Planet's surface with new and improved methods. They will be able to use remote sensing and other means to gain better knowledge of the exact conditions of what lies above and underneath the surface.
