Mars who? Hot on the heels of NASA announcing two new Venus missions, the European Space Agency is hopping on board the Venus train by giving the go-ahead to its own mission, called EnVision.
Earth and Venus have been called twins, but Earth grew up into a life-friendly water world while Venus became an inferno of a planet with sulfuric acid clouds. EnVision will provide "a holistic view of the planet from its inner core to upper atmosphere to determine how and why Venus and Earth evolved so differently."
ESA isn't going it alone. NASA will be a collaborator and provide a radar instrument called Vensar to make high-resolution measurements of the planet's surface. EnVision will also monitor atmospheric gases, analyze the surface composition and look for signs of active volcanoes.
Venus' atmosphere is a particularly intriguing study target after a 2020 paper suggested the gas phosphine -- which sometimes has a biological origin -- may be present in the planet's clouds. Researchers are wondering if Venus once was habitable, or might even host some form of microbial life now.

"Together with the newly announced NASA-led Venus missions, we will have an extremely comprehensive science program at this enigmatic planet well into the next decade," said ESA director of science Günther Hasinger in a statement on Thursday.
Mars doesn't need to worry. There's plenty of planetary love to go around.
