Title: Shared Venus Science Objectives: NASA and Russian Space Research Institute

NASA Studying Shared Venus Science Objectives with Russian Space Research Institute

A team of NASA-sponsored scientists will meet with the Russian Academy of Sciences' Space Research Institute (IKI) next week to continue work on a Joint Science Definition Team study focused on identifying shared science objectives for Venus exploration. The visit comes after a report was recently delivered to both NASA Headquarters in Washington and IKI in Moscow, assessing and refining the science objectives of the IKI Venera-D (Venera-Dolgozhivuschaya) Mission to Venus, Earth's closest planetary neighbor.

"While Venus is known as our 'sister planet,' we have much to learn, including whether it may have once had oceans and harbored life," said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington. "By understanding the processes at work at Venus and Mars, we will have a more complete picture about how terrestrial planets evolve over time and obtain insight into the Earth's past, present and future."

Title: A Clockwork Rover for Venus

A Clockwork Rover for Venus

A concept inspired by clockwork computers and World War I tanks could one day help us find out. The design is being explored at NASA's Jet Propulsion Laboratory in Pasadena, California.

The Automaton Rover for Extreme Environments (AREE) is funded for study by the NASA Innovative Advanced Concepts program. The program offers small grants to develop early stage technology, allowing engineers to work out their ideas.

AREE was first proposed in 2015 by Jonathan Sauder, a mechatronics engineer at JPL. He was inspired by mechanical computers, which use levers and gears to make calculations rather than electronics.

By avoiding electronics, a rover might be able to better explore Venus. The planet's hellish atmosphere creates pressures that would crush most submarines. Its average surface temperature is 864 degrees Fahrenheit (462 degrees Celsius), high enough to melt lead.
