Fuel exhaustion - "Venus Express" finally ushered in a moment of dying

According to foreign media reports, the European Space Agency (ESA) announced that the "Venus Express", which has been serving them for eight years, finally ushered in the moment of its end. "Venus Express" entered the orbit of Venus in April 2006. In fact, the original space mission time of the "Golden Express" was not so long. At that time, the ESA only intended to perform a two-year space exploration mission.

But this time, because of the exhaustion of fuel, the "Golden Express" completely ended the task.

It is understood that at the beginning of this year, because the "Venus Express" rocket fuel is not much, it is likely to fall into the Venus atmosphere from the original orbit and eventually burned. In order to get rid of the fate of the "Golden Express", the ESA carried out an experimental technique called aerobaraking from June 18th to July 11th. Under the efforts of the researchers, the "Venus Express" entered a new elliptical orbit and escaped the burnt catastrophe. However, in the process, in order to stabilize the spacecraft, the staff had to open 15 thrusters. In other words, some energy has to be consumed in the process. ESA hopes that in the future, a certain weather resistance deceleration will allow the spacecraft to enter the planetary orbit without consuming a little fuel.

But unfortunately, although the air-resistance deceleration successfully prevented the "Venus Express" from falling into the Venus atmosphere, it is only a temporary solution. In order to extend the mission life of this spacecraft to next year, the ESA had to ignite a new set of engines from 23 to 30 last month. Unfortunately, this experiment was not successful. From November 28th, ESA lost the signal of "Venus Express". Although the ESA was reconnected to the spacecraft's telemetry and communication signals, they were intermittent. Obviously, the ESA was unable to control the spacecraft.

ESA said that they are also not aware of the exact amount of fuel remaining on the Venus Express. Now, this spacecraft has been unable to change the fate of the orbit and eventually falling into the atmosphere of Venus.
