The COVID-19 pandemic has underscored the critical need for robust scientific evidence to support policy decisions, such as around the effectiveness of various social distancing measures and the safety of drug therapies. Yet this need arises at a time of growing misinformation and poorly vetted facts repeated by influential sources. To address this gap, a group of scientists led by Kai Ruggeri, a professor at Columbia University Mailman School of Public Health, and James Green, chief scientist at NASA, has introduced a new framework to help set standards for the quality of evidence used in policymaking.

NASA has recently been planning a new mission called Mars 2020, which entails sending a helicopter to Mars, alongside conventional ground rovers. While the main objective of this mission is to test the feasibility of operating the helicopter on the red planet, if successful, it could open up new possibilities for Mars exploration. In other words, this mission could pave the way toward other missions involving the deployment of Mars copters, which may be able to produce more information about the ground, terrain and obstacles ahead of the rovers.
