In general, testing is finding out how well something works. In terms of human beings, testing tells what level of knowledge or skill has been acquired. In computer hardware and software development, testing is used at key checkpoints in the overall process to determine whether objectives are being met. For example, in software development, product objectives are sometimes tested by product user representatives. When the design is complete, coding follows and the finished code is then tested at the unit or module level by each programmer; at the component level by the group of programmers involved; and at the system level when all components are combined together. At early or late stages, a product or service may also be tested for usability.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.

3. LAUNCHDAY 02 06 2003
• Waarom deed men de lancering net die dag?
Men deed dit omdat mars die dag het dichtst bij de aarde was.
Dit doet zich om de 26 maanden voor.
• De lancering gebeurde van af een Russische Soyuz/Fregat
lanceerder.
• Samen met deze satteliet werd ook de Beagle 2 naar Mars gestuurd.
4. INSTRUMENTEN AAN BOORD
• - High Resolution Stereo Camera
• -OMEGA Visible and Infrared Mineralogical Mapping Spectrometer
• -SPICAM Ultraviolet and Infrared Atmospheric Spectrometer
• -Planetary Fourier Spectrometer
• -ASPERA Energetic Neutral Atoms Analyser
• -Mars Radio Science Experiment
• -MARSIS Sub-Surface Sounding Radar Altimeter
5. BEAGLE 2
• -Lander meegenomen door de Mars Express
• -Missie geleid door Verenigd Koninkrijk
• -Gepland om te landen op Isidis Planitia om er
de mineralen te bestuderen en naar sporen van
leven te zoeken
• -Is echter verloren gegaan in de atmosfeer
6. MARS EXPRESS ORBITER
• De satelliet was echter wel succesvol en heeft al veel belangrijke wetenschappelijke
missies succesvol afgerond waaronder:
• -Hoge resolutie foto’s
• -Radaronderzoek van de permafrost
• -De precieze samenstelling van de atmosfeer
• Bovendien kan hij nog een grote rol spelen bij toekomstige missies naar Mars
