Since 2004, original interviews, original reporting, and the only regularly published news feature documenting NASA’s first overland expedition of the Red Planet through the adventures and discoveries of Opportunity, Spirit, and the MER team, by A.J.S. Rayl. If you're new to the mission or want a list of all our resources, check out our MER mission page.
It’s a fall afternoon at Endeavour Crater. The summer winds finally lost their energy and the dust storm season is over. But there are no more signals coming from Earth. No more comm sessions with the orbiters. Nothing like it used to be.
As the global storm that wrapped the Red Planet in a cloud of dust since late June finally gave up the ghost in September, the sky continued to clear over Endeavour Crater and the Opportunity team initiated the NASA-approved two-step plan to reestablish contact with the rover.
The dust raising power of the storms that wrapped Mars in a cloud in June and July diminished in August. Meanwhile, on Earth, the Opportunity team at NASA’s Jet Propulsion Laboratory reviewed recovery plans, conducted additional simulations, and began wrapping the month with newfound reasons to believe Opportunity can emerge from her hibernation.
As Opportunity slept in Perseverance Valley under the thick cloud of dust that has blanketed the Red Planet for the last six weeks, scientists who are studying the monster storm that forced the robot field geologist into its hibernation mode are now reporting the tempest has peaked.
As a monster dust storm grew to encircle the Red Planet in June, Opportunity spent most of the month in the dark, presumably sleeping in a hibernation mode as the skies over Endeavour Crater became darker and darker.
Our Mars Exploration Rovers (MER) update has recorded the journeys of the twin rovers Spirit and Opportunity on the surface of Mars since their arrival in January of 2004. It is a treasure trove of information, insight, and high-quality reporting detailing every step of this unprecedented voyage of discovery.
