NASA's Psyche spacecraft will pass 2,800 miles above Mars on May 15, using the planet's gravity to alter its trajectory and increase its speed toward its primary target, the metallic asteroid Psyche. The mission team will use the flyby to test scientific instruments and collect thousands of observations of Mars. The Deep Space Network and several Mars orbiters and rovers will monitor the event to confirm its success.
Facts First
- Psyche will fly 2,800 miles above Mars on May 15, traveling at approximately 12,333 mph.
- The maneuver uses Mars's gravity to alter the spacecraft's path, increasing its speed and reducing propellant usage.
- The mission team will test the spacecraft's multispectral imager by collecting thousands of observations of Mars.
- Mission controllers will use the Deep Space Network (DSN) to monitor radio signals and confirm the flyby's success.
- The mission aims to reach the metallic asteroid Psyche in 2029 after launching in October 2023.
What Happened
NASA's Psyche spacecraft is scheduled to perform a flyby of Mars on May 15, passing 2,800 miles (4,500 kilometers) above the planet's surface. The spacecraft will be traveling at approximately 12,333 mph (19,848 kph) during the encounter. The primary purpose of the flyby is to use Mars's gravity to alter Psyche's path and increase its speed, which reduces propellant usage for its long journey. The mission team plans to use the spacecraft's multispectral imager to collect thousands of observations of Mars during the encounter.
Why this Matters to You
This flyby represents a critical, fuel-saving step in a mission to explore a unique metallic asteroid, which could provide insights into the building blocks of planetary cores. The successful use of a gravity assist could become a model for making future deep-space missions more efficient and cost-effective. The scientific data collected during the flyby may contribute to a better understanding of Mars and its environment.
What's Next
Mission controllers will use the Deep Space Network (DSN) to monitor radio signals to confirm the flyby's success and determine the spacecraft's updated speed and trajectory. Engineers plan to process images from the flyby by adjusting brightness and contrast to create a time-lapse sequence. The spacecraft's next major milestone is its arrival at the metallic asteroid Psyche in 2029.
