Latest SHARAD Stories
For a number of decades now, astronomers have wondered about water on Mars. Thanks to ESA's Mars Express, much of the speculation has been replaced with facts. Launched on June 2 2003, Mars Express has changed the way we think of Mars.
NASA's Mars Reconnaissance Orbiter has extended the long-armed antenna of its radar, preparing the instrument to begin probing for underground layers of Mars.
Two Mars orbiter missions will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing the first direct clues about the Red Planet's subsurface structure.
The Mars Express radar, MARSIS, has now been deployed for more than four months. Here we report on the activities so far.
In August 2003, as the twin Mars Exploration Rovers were barreling toward Mars in their flying saucers, scientists and engineers sent a radio signal disguised as the rovers' "voice" to the Odyssey orbiter at Mars.
The Mars Reconnaissance Orbiter launched on August 12, and when it arrives at Mars it will search for evidence of water in the martian atmosphere, surface, and subsurface. This orbiter also will provide detailed surveys of the planet, identifying any obstacles that could jeopardize the safety of future landers and rovers.
MARSIS, the sounding radar on board ESAâ€™s Mars Express spacecraft, is collecting the first data about the surface and the ionosphere of Mars.
The use of orbiting radar to probe the first three miles underneath the martian surface has been greenlighted. Following review board panels to assess the feasibility, the Mars Express probe will commence its underground searching in May.
