科学目标。 MAVEN 的科学目标旨在确定随着时间的推移，从火星大气层到太空的挥发物损失所发挥的作用，使我们能够了解火星大气层和气候、液态水和行星宜居性的历史。 MAVEN 将确定高层大气、电离层以及与太阳风相互作用的当前状态；确定当前中性子和离子逃逸到太空的速率以及控制它们的过程；并确定稳定同位素的比率，这将告诉我们随着时间的推移损失的历史。
Science objectives. The MAVEN science goals are aimed at determining the role that loss of volatiles from the Mars atmosphere to space has played through time, allowing us to understand the histories of Mars’ atmosphere and climate, liquid water, and planetary habitability. MAVEN will determine the current state of the upper atmosphere, ionosphere, and interactions with the solar wind; determine the current rates of escape of neutrals and ions to space and the processes controlling them; and determine the ratios of stable isotopes that will tell us the history of loss through time.
