Big Questions for Solar Orbiter

Solar Orbiter is a European Space Agency (ESA) mission to study the Sun from a distance closer than any spacecraft previously has, and will provide images and measurements in unprecedented resolution and detail. This mission is part of SMD's LWS program.

What are the hazards and resources in the Solar System environment that will affect the extension of human presence in space?

Harsh conditions in the space environment pose significant risks for the journey of exploration. Although space is a near-vacuum, the very-thinly-spread particles and fields are like an ocean that can affect the spacecraft and astronauts that travel through it. Like seafaring voyagers, space explorers must be constantly aware of the current space weather and be prepared to handle the most extreme conditions that might be encountered.
