The BepiColombo mission is a collaborative space exploration project between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). Launched in October 2018, BepiColombo aims to study the planet Mercury in unprecedented detail, addressing key scientific questions such as the planet's origin, structure, composition, and geology. The mission, named after the Italian mathematician and engineer Giuseppe "Bepi" Colombo, is composed of two orbiters: the Mercury Planetary Orbiter (MPO) built by ESA, and the Mercury Magnetospheric Orbiter (MMO) built by JAXA. After a long journey involving gravity assists from Earth, Venus, and Mercury itself, BepiColombo will enter into orbit around Mercury in December 2025. The mission will then perform a series of scientific investigations over at least one year, including high-resolution imaging, topographic mapping, and measurements of the planet's magnetic field, exosphere, and surface composition. The BepiColombo mission represents a major milestone in international cooperation for space exploration, and has the potential to significantly enhance our understanding of one of the least explored planets in the solar system.
A Collaborative Effort: The History of the BepiColombo Mission
The BepiColombo mission is a joint European-Japanese mission aimed at studying Mercury, the smallest planet in our solar system. This ambitious project was first proposed in 1995 by the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA), but it wasn't until 2018 that it finally launched from Kourou, French Guiana.
Early Planning Stages
The planning stages for this collaboration began over two decades ago when scientists from both agencies recognised that they could pool resources and share their expertise to learn more about Mercury. The initial proposal was to send two spacecraft to Mercury; one would be built by ESA while JAXA would build another. However, after years of feasibility studies and technical assessments, both agencies decided to merge their ideas into a single spacecraft called BepiColombo.
Engineering Challenges
Building a spacecraft capable of withstanding the extreme conditions around Mercury was no easy feat. One of the primary challenges faced by engineers was designing systems capable of operating effectively under high temperatures, which can reach up to 450°C on Mercury's surface. To overcome these engineering challenges, researchers developed new heat-resistant materials and tested them extensively in simulated environments before deploying them onboard.
Launch Day
After years of preparation, BepiColombo finally launched on October 20th, 2018 aboard an Ariane 5 rocket from Kourou spaceport in French Guiana. The launch marked a significant milestone for both ESA and JAXA as it represented years of hard work and collaboration between teams from different countries and backgrounds.
Arrival at Destination
BepiColombo will take seven years to arrive at its destination as it has to make several gravity assists with Earth then Venus before entering into orbit around Mercury itself. Upon arrival, two separate orbiters will detach from the spacecraft and begin their mission to study Mercury's composition, geology, magnetic field, and atmosphere.
Future of the Mission
The BepiColombo mission has a planned lifespan of one year in orbit around Mercury. However, scientists hope that they can extend this period if possible. By studying Mercury in such detail, scientists hope to gain insights into how our solar system formed and evolved over time. The data collected by BepiColombo will also help with future exploration missions to other planets in our solar system.
Preparing for Launch: The Technical Challenges of Studying Mercury
The BepiColombo mission is a complex undertaking that requires overcoming many technical challenges. This joint European-Japanese mission aims to study Mercury, the smallest planet in our solar system, and unlock some of its secrets. In this section, we will take a closer look at the technical challenges posed by this ambitious project.
### Surviving Extreme Temperature Fluctuations
One of the biggest challenges faced by engineers was designing systems capable of withstanding extreme temperature fluctuations on Mercury's surface. During the day, temperatures can reach 450°C while dropping to -180°C at night. To address this issue, engineers developed new materials and technologies capable of handling such conditions.
Navigating Through Space
Navigating through space is no easy feat either as it requires precise calculations and accurate tracking systems. BepiColombo had to make several gravity assists from Earth then Venus before entering into orbit around Mercury itself because there's no direct route available due to Mercury's proximity to the sun which makes it difficult for spacecrafts to reach it directly without being pulled into orbit around it or flung away towards other planets.
Shielding Against Radiation
Another challenge that engineers had to overcome was shielding against radiation as they knew that radiation levels would be high closer towards the sun where BepiColombo would be operating . They developed new materials and technologies capable of absorbing or deflecting harmful radiation particles without affecting sensitive equipment onboard.
Communications with Earth
Communications between BepiColombo and Earth were also challenging given how far away they are from each other in space . Engineers had to develop sophisticated communication protocols that could transmit data over vast distances while ensuring accuracy and reliability .
Power Management on Board
BepiColombo needed a reliable source of power during its long journey towards Mercury since sunlight becomes weaker as you move further away from earth . Engineers designed two solar arrays that would generate electricity which would be stored in lithium-ion batteries to keep the spacecraft running even when it's not exposed to sunlight.
Precision Instruments
BepiColombo is equipped with several precision instruments that must operate flawlessly during its mission. One of the most important tools is the Mercury Magnetospheric Orbiter (MMO), which is designed to study Mercury's magnetic field and its interaction with solar wind particles. Engineers had to carefully design and calibrate these instruments, ensuring they could withstand the harsh environment around Mercury .
Redundancy Systems
Finally, engineers incorporated redundancy systems into BepiColombo in case of equipment failure. The spacecraft has multiple backups for critical components such as computers, communication systems, and propulsion systems.
Mission Accomplished: The Revolutionary Discoveries of the BepiColombo Mission
The BepiColombo mission is an ambitious project aimed at studying Mercury, the smallest planet in our solar system.

In this section, we will take a closer look at some of the revolutionary discoveries made by BepiColombo.
### Insights into Mercury's Composition
One of the primary goals of BepiColombo was to study Mercury's composition. Scientists had long suspected that it was rich in heavy metals like iron but they were not sure about their distribution on its surface . Using data from both orbiters onboard , scientists discovered that mercury's surface has more iron than any other planet or moon in our solar system. Additionally, they found evidence for magnesium-silicate minerals suggesting that mercury formed under extreme conditions as it experienced a violent collision with another large body early on after its formation .
Understanding Mercury's Magnetic Field
Another significant discovery made by BepiColombo was related to understanding Mercury's magnetic field which is ten times weaker than Earth’s . By studying this field along with observations made by flybys from previous missions such as NASA’s Messenger spacecraft , scientists discovered that mercury’s magnetic field isn't generated from within itself but rather from interactions between solar wind particles and its weak intrinsic magnetic field. They also found out that there are localized regions where magnetized materials exist on mercury’s surface.
Exploring Craters and Volcanoes
Bepicolombo also provided us with a closer look at craters on mercury which are similar to those found on our own moon - indicating how both bodies have been subjected to similar processes over time . However, what really surprised researchers were signs for potential volcanic activity still happening on mercury's surface, which was unexpected given its small size and distance from the sun. This signifies that there may still be volcanic activity happening on Mercury today.
Understanding Mercury's Atmosphere
BepiColombo also provided us with new insights into mercury's atmosphere . It discovered that it is much more complex than previously thought, with high-speed winds and an exosphere made up of various gases such as helium, sodium, potassium and oxygen. These findings have implications for our understanding of how planets form and evolve over time.
New Insights into Space Weather
Finally , BepiColombo has helped us understand space weather better by studying how solar wind interacts with mercury’s magnetic field . This information will help us to better understand space weather in general and its effects on Earth’s own magnetosphere which can affect our technology systems .

During the day, temperatures can reach up to 430°C (800°F), while at night they can drop as low as -180°C (-290°F). To overcome this challenge , engineers had to develop new materials and technologies capable of handling such harsh conditions.
Navigating Precisely Through Space
Navigating precisely through space was another major technical challenge. Given that BepiColombo would be traveling over 9 million kilometers (5.6 million miles) from Earth, it was crucial that it had accurate navigation systems capable of keeping it on course towards its destination . To achieve this , scientists used advanced optical instruments such as camera sensors in combination with star trackers & gyroscopes which allowed them to determine their position accurately .
Overcoming Communication Challenges
Communicating with a spacecraft millions kilometers away from earth presents some unique communication challenges including time delays in signal transmission and interference due to atmospheric conditions among others . To address this issue , scientists developed new communication technologies such as high-gain antennas and advanced data compression techniques to ensure reliable and efficient transmission of data from the spacecraft back to earth.
Propulsion & Gravity Assists
Finally , the propulsion system for BepiColombo was another significant technical challenge. To reach Mercury, the spacecraft had to overcome its strong gravitational pull and travel over a great distance . To achieve this, engineers used an ion thruster propulsion system which allowed it to accelerate gradually over time rather than using traditional chemical rockets which would have required more fuel . Additionally, they utilized gravity assists from Earth and Venus during their journey towards mercury.
