On their years, mission to mercury is the probe bepicolombo on thursday morning (cest) at venus passed. "It all worked, it was successful", said simon plum from the esa satellite control center (esoc) in darmstadt of the german press agency. In the coming week, a precise analysis has now been made. Shortly before 6.00 clock flew far over a billion euros expensive european-japanese spacecraft in good 10.000 kilometers away from the neighboring planet of the earth. The manover was controlled from the control center in darmstadt.
Brake on the planet
Flow past planets are necessary for bepicolombo to reduce speed. Only in this way can the spacecraft can brake the thrust through the solar gravity and sometimes swivel with the calculated speed in a stable orbit around the mercury. On thursday morning, the speed reduced almost a tenth to about 34 kilometers per second.
An a similar manobever flew bepicolombo last april as the probe for a flight to less than 12.700 kilometers of the earth took. On the flight to mercury, the smallest and fastest planet in our solar system, the probe will fly past the venus in just 550 kilometers in the coming august in just 550 kilometers and a total of six times at mercury before it swings in its final orbit in 2025. After about seven years of flight time, the 2018 started probe then resumed around nine billion kilometers.
Venus access in focus
At the flight around venus, the probe collected data and also shot pictures. Seven of eleven instruments on board should raise science data from venus. The neighboring planet of the earth was broken in the focus in the focus. In september, astronomers had announced that they have discovered the gas monophosphane in venus atmosphere. On earth, this is mainly due to biological processes that take place under exclusion of oxygen. However, the researchers argued that the detection in venus atmosphere is not a durable document for a biological source on the planet.
The merkur mission is the first european to go to the sun on the next planet. On the probe sit two orbites from germany and japan. After swinging the probe in a circulation path around the merkur 2025, the magnetic field, the surface and also the solar winds examine.
