Expectations as Asteroid-Probing Spacecraft Nears Mars
The pioneering mission to explore the asteroid known as Psyche is making a significant pit stop today. The spacecraft, on its journey to the aforementioned asteroid, is going to have an exciting encounter with Mars, coming as close as approximately 2,800 miles from the Red Planet.
Boosting Speed and Adjusting Path with Martian Gravity
During this flyby, the spacecraft will harness the gravitational pull of Mars to give itself an impressive speed boost to its already staggering 12,333 miles per hour. This will allow the spacecraft to adjust its current path towards the 173-mile-wide asteroid known as 16 Psyche, or simply Psyche. This metal-rich asteroid resides in the primary asteroid belt situated between Mars and Jupiter.
The spacecraft, which began its journey in late 2023, is anticipated to reach its named target, the Psyche asteroid, in 2029. This will provide scientists with a unique opportunity to study a truly remarkable celestial body. It is believed that 16 Psyche is an early solar system planetesimal, a celestial body that aids in the formation of planets, that has lost its outer layers due to billions of years of collisions. Therefore, its exposed nickel-iron core offers a rare glimpse into the usually hidden cores of rocky planets.
Calibrating Instruments and Conserving Propellant
But the spacecraft's interaction with Mars doesn't just benefit it in terms of speed. The flyby will also provide the spacecraft with an opportunity to test and calibrate the instruments it will be employing once it reaches the main asteroid belt. In addition, this maneuver will help conserve the spacecraft's xenon gas propellant.
To achieve this, the spacecraft's multispectral imager will be put to work, capturing thousands of observations of Mars. This process has already started earlier this month.
Preparation and Expectations for Mars Encounter
Preparations for the spacecraft's encounter with Mars began with a trajectory correction maneuver performed earlier in the year. This maneuver, which involved firing the spacecraft’s thrusters for 12 hours, increased the spacecraft's speed and refined its approach to Mars.
The mission planning lead, Sarah Bairstow, stated that they are now precisely on target for the flyby. They have programmed the flight computer with all the necessary instructions that the spacecraft will execute throughout the month. Bairstow emphasized that this is their first in-flight opportunity to calibrate the spacecraft's imager with an object larger than a few pixels. They also plan to make observations with the mission's other scientific instruments.
Scientists believe that the spacecraft may detect a faint dusty ring, or torus, around Mars. This is thought to be a result of tiny space rocks, or "micrometeorites," striking the surfaces of Mars' two moons, Phobos and Deimos, and ejecting dust particles into space. The alignment of the sun, the spacecraft, and Mars could cause this dusty material to scatter sunlight, making it visible to the spacecraft's instruments.
