Mangalyaan is a technology demonstration project, aimed at devel- oping the technologies needed for designing, planning and carrying out interplanetary missions. The spacecraft also has a science payload, consisting of a colour camera, which has returned many stunning and detailed images, and other scientific instruments for studying the mor- phology and composition of surface features, as well as the Martian atmosphere. While MOM has not delivered many new science results as yet, the mission itself is considered a big success, as all of its engineering goals have been achieved, and the spacecraft has outlived its expected lifespan. ISRO will certainly be able to embark on future interplanetary missions with confidence. MAVEN – The search for Mar’s lost atmosphere Launched in November 2013, the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is the first one dedicated to exploring the Red Planet’s tenuous upper atmosphere. Its main aim is to try and help scientists understand the climate history of the planet. Key goals for investigation are the role of the solar wind in stripping away the at- mosphere, its current state and rates of gas loss to space today. By then extrapolating back through time, scientists will be able to determine the evolution of Martian climate, the total atmospheric loss over Mars’ 09 www. RocketSTEM .org 09
