The European Space Agency has announced that two spacecraft are set to fly near Venus this week, with the first fly-by set for today.
Both spacecraft will be headed to the center of our solar system, where one of them is meant to study Mercury and the other one the sun’s poles.
There will be pictures available by August 10, but it is not possible to take high-resolution images of Venus with the science cameras onboard either mission, the ESA said.
The main camera on one of the probes will be facing the sun, while the other’s main camera is still obscured by scientific equipment set for Mercury.
The European Space Agency’s Solar Orbiter probe was developed in cooperation with NASA and will be the first to swing around Venus early Monday.
Solar Orbiter will use the gravitational pull of Venus to help put it on track to observe the sun’s poles.
Approximately 33 hours later, the orbit of Venus will get a visit from the European-Japanese spacecraft BepiColombo. Its plan is to use the pull of Venus to slow down and safely steer into Mercury’s orbit by 2025.
Elsa Montagnon, the spacecraft operations manager for BepiColombo told AP, “Without the flyby, we would not be able to reach our target planet,” adding, “The energy required to enter into orbit of Mercury would be prohibitively expensive in terms of propellant.”
BepiColombo needs to fly by Earth, Venus and Mercury in order to get to Mercury’s orbit due to the intense gravitational pull of the sun.
At the beginning of October, BepiColombo is scheduled to see Mercury for the first time in one of the six planned flybys. Come October, BepiColombo will be within just 200 kilometers (124 miles) distance.
By the end of the decade, NASA and the European Space Agency plan three more missions to the orbit of Venus.
