Marc Rayman's monthly check-in with the Dawn mission describes the achievements of the spacecraft in its Low-Altitude Mapping Orbit (including near-global high-resolution imaging!) and explains what's next.
Last week, India launched RISAT 1, a new Earth-observing satellite. How does its synthetic aperture radar compare to that of Envisat, which has fallen silent?
An update primarily to reassure readers that yes, we will have A. J. S. Rayl's MER updates back; the May 1 one will be a bit delayed but is coming soon.
