Critical reflection

  Module learning: At the start of the module, we were asked to write a letter to our professor stating why we joined this course, what our weaknesses were and what we hoped to learn from this module. I had mentioned in the letter that my biggest weakness was not being very comfortable or forthcoming when it came to presenting in front of large groups. At the start of the module, I wasn’t very forthcoming in presenting in front of the entire class but as we went ahead in the module, I slowly started to become more comfortable in presenting in front of everyone due to the ample amount of practice sessions and positive feedbacks given after every presentation. The prime example of one such practice session was during week 2 when all of us were teamed together in groups of 4. My team members were Elson, Ruth and Clarissa. Each team was given the task of presenting what reflective thinking was. Our team chose to present Dewey’s model of reflective thinking and Rodger’s model of reflective

Reader response draft 3.0

  The article “NOMAD, an Integrated Suite of Three Spectrometers for the ExoMars Trace Gas Mission: Technical Description, Science Objectives and Expected Performance”, discusses a spectrometer suite incorporated into the ExoMars Trace Gas Orbiter, NOMAD (“Nadir and Occultation for Martian Discovery”). NOMAD comprises of three spectrometers: Solar Occultation (SO), Limb and Nadir Occultation (LNO) and Ultraviolet/Visible Spectrometer (UVIS). The SO spectrometer only performs solar occultation and works in the infrared range(2.3-4.3um). The LNO spectrometer is capable of performing solar and nadir occultation and limb observations and also operates in the infrared range(2.3-3.8um. The UVIS spectrometer operates in the ultraviolet and visible light range(200-650nm) and can be used to detect carbon dioxide ice grains at high altitudes. These spectrometers work with each other to collect data which allows us to understand Mars’ “atmospheric composition and the related physical and chemical

The article “NOMAD, an Integrated Suite of Three Spectrometers for the ExoMars Trace Gas Mission: Technical Description, Science Objectives and Expected Performance”, discusses a spectrometer suite incorporated into the ExoMars Trace Gas Orbiter, NOMAD (“Nadir and Occultation for Martian Discovery”). The article mentions that the purpose of NOMAD is to study the trace gases, clouds and dust present within Mars’ atmosphere. The main purpose of the Trace Gas Orbiter (TGO) is to detect and quantify trace gases on Mars, a process that is only possible with NOMAD since it was specifically designed to detect and quantify these gases. The NOMAD satellite is equipped with three spectrometers which allows it to measure the spectral emissions from the atmosphere, spanning ultraviolet, visible light, and infrared wavelengths. According to the article “NOMAD, an Integrated Suite of Three Spectrometers for the ExoMars Trace Gas Mission: Technical Description, Science Objectives and Expected Perform

Summary Draft 1 of Exomas Trace Gas Orbiter

Exomas Trace Gas Orbiter (TGO) search for traces of atmospheric gases on Mars that could be evidence of ongoing biological and geological processes. Biomarkers reveal the possibility of life on Mars. The TGO comprises of 4 scientific instruments to help achieve its goal - Atmospheric Chemistry Suite, Colour and Stereo Surface Imaging System, Fine Resolution Epithermal Neutron Detector and Nadir and Occultation for Mars Discovery (NOMAD).  NOMAD uses solar occultation and reflected light nadir observations to identify methane and other atmospheric constituents. It has three spectrometers, two infrared and one ultraviolet. An instrument with three spectrometers is used: one for solar occultation measurements alone, one for both limb and occultation measurements simultaneously, and one for ultraviolet and visible measurements as well. It will detect isotopologues of many key Martian atmospheric species. NOMAD will provide global 4D views of the atmosphere of Mars by combining 2-D-vertical
