Flying to Mercury
About Mercury
Mercury, named after the Roman messenger god, is one of the most fascinating planets in our solar system.
As the closest planet to the Sun, Mercury enjoys a unique position in our cosmic neighborhood.
Its proximity to our star has posed numerous challenges for space exploration, but has also provided valuable
insights into the formation and evolution of planets.
Challenges of reaching Mercury
Journeying to Mercury is no easy feat due to its extreme orbit. The planet’s proximity to the Sun means that
it experiences intense gravitational pull, requiring tremendous energy to escape its gravitational hold.
Additionally, the extreme temperatures on Mercury’s surface pose obstacles to both humans and technology.
During the day, surface temperatures can reach a scorching 800°F (430°C), while at night, they plummet to
-290°F (-180°C).
MESSENGER Mission
The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) mission, launched in 2004, was
NASA’s first mission to Mercury since 1975. It took nearly seven years for MESSENGER to reach its destination
by utilizing multiple gravity assist flybys of Earth, Venus, and Mercury itself. Once in orbit, MESSENGER
orbited Mercury for four years, collecting valuable data about its geology, surface composition, magnetic
field, and much more.
BepiColombo Mission
Building on the success of the MESSENGER mission, the European Space Agency (ESA) and the Japan Aerospace
Exploration Agency (JAXA) launched the joint BepiColombo mission to Mercury in 2018. BepiColombo aims to
further explore and understand Mercury’s mysteries through a series of flybys, before entering into orbit by
2025. This ambitious mission consists of two orbiters, one designed to study Mercury’s surface and
exosphere, while the other focuses on the planet’s magnetosphere.
Future endeavors
Exciting advancements in technology and a deepening curiosity about our solar system have sparked interest
in exploring Mercury further. Future missions are being planned to investigate the possibility of water ice
in permanently shadowed craters near Mercury’s poles. Understanding the unique characteristics of this rocky
planet will not only deepen our knowledge of the universe but also provide valuable insights into the
formation and development of our own planet.
