MESSENGER's Endgame: Hover Campaign Promises Bird's-Eye View of Mercury's Surface
Mercury, the smallest planet in our solar system, has always been a mystery to scientists. However, with the help of NASA's MESSENGER spacecraft, we have been able to gather a wealth of information about this enigmatic planet. After four years of orbiting Mercury, MESSENGER is now in its final phase, the Hover Campaign, which promises to provide us with a bird's-eye view of Mercury's surface. In this article, we will explore the Hover Campaign and what it means for our understanding of Mercury.
Introduction
Mercury is a planet that has always fascinated scientists. It is the closest planet to the sun and has a unique set of characteristics that make it stand out from the other planets in our solar system. However, due to its proximity to the sun, it has been difficult to study Mercury in detail. That is until NASA's MESSENGER spacecraft was launched in 2004.
The MESSENGER Mission
The MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) spacecraft was launched in 2004 with the goal of studying Mercury in detail. After a six-year journey, MESSENGER entered into orbit around Mercury in 2011. Over the next four years, MESSENGER collected a wealth of data about Mercury's surface, composition, and magnetic field.
The Hover Campaign
After four years of orbiting Mercury, MESSENGER is now in its final phase, the Hover Campaign. The Hover Campaign is a series of low-altitude orbits that will allow MESSENGER to get a closer look at Mercury's surface than ever before. During the Hover Campaign, MESSENGER will orbit at an altitude of just 5 to 10 kilometers above Mercury's surface.
What We Can Expect
The Hover Campaign promises to provide us with a bird's-eye view of Mercury's surface. This will allow us to study the planet in even greater detail than before. Scientists hope to use the data collected during the Hover Campaign to answer some of the remaining questions about Mercury, such as why it has such a large iron core and why its surface is so heavily cratered.
The End of the MESSENGER Mission
Unfortunately, all good things must come to an end, and the MESSENGER mission is no exception. After the Hover Campaign, MESSENGER will make a final descent towards Mercury's surface, where it will crash and burn up. This is a planned end to the mission, as MESSENGER has run out of fuel and can no longer maintain its orbit around Mercury.
Conclusion
The MESSENGER mission has been a great success, providing us with a wealth of information about Mercury. The Hover Campaign promises to provide us with even more data, allowing us to study the planet in even greater detail. While the end of the MESSENGER mission is bittersweet, we can look forward to the discoveries that will be made during the Hover Campaign.
