Two different spacecraft will be swinging by Venus this week

Mars might be the planet in our solar system that gets the most attention from visiting spacecraft, but this week, Venus will be entering the spotlight. The planet will host not one but two visitors as two different craft perform flybys to gain a gravitational boost on their way to other destinations. But the mission operators won’t let this chance to gather some extra information on Venus go to waste, so both craft will be collecting data as they go by.

The first visitor, due to perform its closest approach to Venus on Monday, August 9, is NASA and the European Space Agency (ESA)’s Solar Orbiter. This craft is designed to study the sun, but to get to its target, it is performing repeated flybys of Venus to bring it ever closer to the heart of the solar system.

The second visitor, arriving a day later on Tuesday, August 10, is ESA and Japanese space agency JAXA’s BepiColombo, which will be studying Mercury. It has already passed by Venus before and will make its second Venus flyby to power it on to its eventual destination.

Unfortunately, neither spacecraft will be able to take high-resolution pictures of Venus as they go by because Solar Orbiter needs to remain facing the sun, and BepiColombo will be blocked by its transfer module. However, there will be the opportunity for some pics in 1024 x 1024 pixel resolution, as two of BepiColombo’s monitoring cameras will snap photos of the planet up close and as it moves away.

Plus, Solar Orbiter will attempt to use its SoloHi imager, which is designed to take photos of the solar wind, to try and capture the nightside of Venus.

One serendipitous result of the near-simultaneous flybys is that there will be data available from two different sources in two different locations, which is rarely possible with Venus. Both craft will collect data on the magnetic and plasma environment of Venus, allowing researchers to get a more complete picture of the environment, along with data from the JAXA’s Akatsuki spacecraft currently in orbit there.

NASA’s Lucy spacecraft swings by Earth on its way to Trojan asteroids
see lucy spacecraft slingshot past earth fly by

NASA's Lucy spacecraft is on its way to the Trojan asteroids to learn about the formation of the solar system, but it isn't traveling in a straight line from Earth to the orbit of Jupiter. Instead, it is performing a series of slingshot maneuvers to help it on its journey, including a recent maneuver around Earth. This weekend, a few lucky observers were able to see Lucy as it performed an Earth flyby before heading back out into space.

NASA aces test of robot balloon that could one day explore Venus

Mars gets a lot of attention from earthlings these days, but recently Venus is coming under the spotlight, with NASA, its European counterpart ESA, and New Zealand spaceflight company Rocket Lab all planning to send missions there in the coming years.

Besides these, NASA is also considering exploring the inhospitable planet by sailing a robotic "aerobot" balloon in the Venusian winds.

Rocket Lab plans to send the first private mission to Venus

While for decades Mars has been the planet outside Earth that has arguably received the most attention, in recent years, planetary scientists have been setting their sites on our other neighbor: Venus. This strange planet with its hellishly high temperatures and incredible surface pressure will be the site for two upcoming NASA missions and one European Space Agency mission in the next decade, and these agency missions will also be joined by a private space mission from New Zealand-based company Rocket Lab.

Rocket Lab recently shared more details for its planned mission to Venus in a publication in the journal Aerospace. With a planned launch in 2023, it will be the first private mission to Venus and will use Rocket Lab's Electron rocket and Photon spacecraft.
