Perseverance Rover
The Perseverance-Rover is a robotic rover designed to explore the Jezero Crater on Mars as part of NASA's Mars Exploration Program. Launched on July 30, 2020, from Cape Canaveral Air Force Station in Florida, the rover landed on February 18, 2021. Here are key details about this mission:
Mission Objectives
- Search for Signs of Ancient Life: The primary goal is to investigate the astrobiological potential of Mars, focusing on the search for signs of ancient microbial life.
- Characterize the Geology of Mars: Studying the planet's geology to understand its geological processes and history.
- Collect and Cache Samples: Gather samples of rock and regolith (broken rock and soil) for possible return to Earth in future missions.
- Prepare for Human Exploration: Demonstrate technologies for future human missions, including oxygen production from the Martian atmosphere.
Design and Instruments
- Size and Weight: Perseverance is approximately the size of a car, weighing about 1,025 kg including the descent stage and 254 kg for the rover itself.
- Power: It uses a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) for power, providing electricity from heat generated by the decay of plutonium-238.
- Instruments:
- Mastcam-Z - A pair of zoomable cameras for panoramic imaging and video.
- SuperCam - For studying rock and soil composition from a distance.
- SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) - To detect organic compounds.
- PIXLS (Planetary Instrument for X-ray Lithochemistry) - To map chemical elements at fine scales.
- MEDA (Mars Environmental Dynamics Analyzer) - Measures weather, climate, and radiation.
- RIMFAX (Radar Imager for Mars' Subsurface Experiment) - To study subsurface layers.
- MOXIE (Mars Oxygen ISRU Experiment) - Demonstrates oxygen production.
Landing and Exploration
The rover used a sophisticated landing system known as the Sky Crane, which allowed for a precise touchdown within Jezero Crater. This crater was chosen because it contains a delta where an ancient river flowed into a lake, providing a high potential for finding signs of past life.
Key Milestones
- Launch: July 30, 2020, aboard an Atlas V rocket.
- Landing: February 18, 2021, at Jezero Crater.
- First Drive: The rover took its first drive on Mars on March 4, 2021.
- Ingenuity Helicopter: Perseverance also deployed the first powered, controlled flight on another planet with the Ingenuity Helicopter.
Future Plans
Perseverance is designed to operate for at least one Mars year (about 687 Earth days), with the potential for extended missions. The samples collected by Perseverance are part of the Mars Sample Return Mission, a collaborative effort with the European Space Agency (ESA) to bring these samples back to Earth for detailed analysis.
