The article “NOMAD, an Integrated Suite of Three Spectrometers for the ExoMars Trace Gas Mission: Technical Description, Science Objectives and Expected Performance”, talks about 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. 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. The LNO spectrometer is capable of performing solar and nadir occultation and limb observations. The UVIS spectrometer 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 pr...

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-vert...

 Dear Professor Blackstone, I am writing this letter to you to introduce myself formally. I am Meenatchi Selvaraj but you may call me, Meena. I graduated from DPS International School and I am a year one student studying in the Robotic Systems Engineering programme in Singapore Institute of Technology. I was interested in robotics from a very young age as I used to play with Lego blocks to build a multitude of things such as cars, buildings, etc. As I started to grow older my interest in robotics only flourished more and I soon started to look for various avenues through which I could develop and gain more knowledge about this field. I joined the robotics club in my school and they educated us on the various parts of the electrical components which make up a robotic system. My school teachers continuously encouraged me to pursue this as a career and guided me to apply to SIT’s robotics programme. Thus, I applied to this course to fulfil my dream of becoming a robotic engineer....

Critical thinking and communication are two sides of the same coin that is increasingly needed within the workplace to build a company. Critical thinking can be described as the process of objectively analyzing and evaluating issues to form a judgment. An important quality of an effective leader is the ability to think clearly and analyze problems effectively and then make effective decisions. Effective analysis of problems and situations can only happen if a leader can communicate with other people. If critical thinking is considered as the engine, then communication is the wheel that drives it forward.  I believe that critical thinking will help me to pose crucial questions and issues, stating them clearly and precisely, assess and interpret relevant information using abstract ideas, make well-informed conclusions and solutions, then test them against applicable standards and criteria. To help me make these conclusions, communication is a must and will enable me to be a better an...

  “Without clear lines of communication, our ideas would stay within our own small development teams instead of becoming mature products. While this is obvious to those of us who have become experienced engineers, the real question is: Why is it lost to us when we are engineering students?” Dr. Akbar R Khan, Software Systems Engineer, USA, “Good Communication Is Essential...” (2014) As engineering is  a purely  scientific   discipline ,  many universities give more importance to academics than to communication.  Since   communication   skills   aren't  taught  during the university days, many  engineers   aren't   able   to  communicate  effectively  with their  colleagues. Hence the question "Why is it lost to us when we are engineering students?" is posed.
