Q & A
What was the primary mission of the Opportunity rover?
-The primary mission of the Opportunity rover was to study the geology of Mars, with the main goal of determining whether Mars was ever a place that was conducive to life. This was done by looking at rocks for evidence of water, which would give scientists an idea of what Mars might have been like millions of years ago.
How long was Opportunity designed to last on Mars?
-Opportunity was designed to last for 90 sols (Martian days), but it far exceeded this expectation, surviving for an incredible 15 years on Mars.
What was the cause of the loss of contact with Opportunity in June 2018?
-Contact was lost with Opportunity due to a global dust storm that blocked sunlight from hitting its solar panels for several months, causing it to lose power.
What was the name of the crater where Opportunity landed and where it discovered evidence of past water activity?
-Opportunity landed inside a small crater known as Eagle crater, where it discovered evidence that moving current, possibly water, had shaped the bedrock.
How did Opportunity manage to escape from the 'Purgatory Dune' where it got stuck?
-Opportunity was able to escape from the Purgatory Dune after mission planners on Earth simulated various methods and then ordered the rover to try different maneuvers. Over the course of 20 Martian days, it moved a few centimeters at a time, eventually freeing itself.
What was the name of the largest crater that Opportunity explored?
-The largest crater that Opportunity explored was Victoria crater, which was 730 meters wide.
What was the name given to the fault with Opportunity's robotic arm, where it got stuck frequently?
-The fault with Opportunity's robotic arm was not given a specific name in the script, but it was described as a persistent issue that required the arm to be stowed away during long-distance travels and only used in a 'hover-stow' position for short distances.
What was the name of the final panorama that Opportunity was sending back before losing contact?
-The script does not provide a specific name for the final panorama that Opportunity was sending back, but it is described as being of its final resting place.
What was the translation of Opportunity's famous last communication?
-Opportunity's famous last communication was poetically translated to be 'My battery is low and it's getting dark'.
What was the significance of the 'Marathon Valley' in Opportunity's mission?
-Marathon Valley was significant because it was a waypoint where Opportunity's odometer reading would reach the distance of a typical marathon, symbolizing a major milestone in the rover's mission.
What was the name of the valley that Opportunity was exploring when it lost contact, and what was the aim of the exploration?
-Opportunity was exploring Perseverance Valley when it lost contact. The aim was to determine whether it was water, ice, or wind that had carved this gully.
What was the role of the Mars Reconnaissance Orbiter (MRO) in Opportunity's mission?
-The Mars Reconnaissance Orbiter (MRO) played a role in spotting features of interest on the Martian surface, such as the suspected clays around Endeavour crater, and providing data that helped in planning Opportunity's route and investigations.
Outlines
🚀 Launch and Landing of Opportunity Rover
The first paragraph introduces the Opportunity rover's mission on Mars, which lasted for 15 years before losing contact on June 12, 2018. It highlights the rover's landing inside Eagle crater, its geological mission to search for signs of water, and the discovery of 'vugs' and hydroxide ions indicating past water presence. The rover's journey is marked by various challenges and scientific achievements, setting the stage for future missions like Perseverance.
🏜️ Exploring Craters and Overcoming Obstacles
The second paragraph details Opportunity's exploration of Endurance crater, where it spent 180 Sols studying layered bedrock and confirming the episodic nature of past floods. The rover also investigated its own heat shield and discovered the first meteorite on another planet, named Heat Shield Rock. It faced a major challenge when it got stuck in a sand dune called Purgatory Dune but was successfully freed after 20 Martian days.
🔬 Scientific Discoveries and Collaborations
The third paragraph discusses Opportunity's collaboration with the Mars Express Orbiter and its encounter with a dust storm, which affected the rover's power generation. It also covers the rover's first mechanical fault with its arm and the various measures taken to mitigate its impact. Opportunity's journey continued with the study of the Payson outcrop, which showed diverse sedimentary textures likely formed by wind and water processes.
🌍 Victoria Crater and the Search for Martian Oceans
The fourth paragraph describes Opportunity's travels towards and arrival at Victoria crater, the largest and most impressive crater it encountered.

Victoria's steep slopes and sand dunes presented both scientific opportunities and navigational challenges.
🚶♀️ Journey to Endeavour Crater and Discovery of Clays
The fifth paragraph follows Opportunity's trek towards Endeavour crater, believed to contain clays that would indicate past water presence. The rover faced a major arm fault but managed to overcome it. The journey was long and arduous, with Opportunity studying various rocks, including meteorites, and eventually reaching the rim of Endeavour crater after a two-year journey.
🔋 Power Struggles and the Long Trek to Solander Point
The sixth paragraph highlights the challenges Opportunity faced due to Martian dust storms and the decreasing power of its solar panels. Despite these struggles, the rover continued its mission, making its way to Solander Point, a north-facing slope that would maximize solar power generation during the Martian winter. The rover's onboard computer issues and the reformatting of its flash memory are also discussed.
🌌 Comet Siding Spring Flyby and Marathon Valley
The seventh paragraph covers the Opportunity rover's observations of the Comet Siding Spring flyby and its effects on Mars' magnetic field.
