The CHopper mission has three primary science goals over the 7.3 years of its nominal lifetime.

The science goals are concerned with the interior structure, history and current state of the Moon.

The science goals are to carry out state-of-the-art cosmological simulations with research areas in:

The science goals for the Webb can be grouped into four themes:

Both spacecraft would be able to operate independently, so that if one failed, the other could still achieve science goals.

After array construction, a few science goals that were not explicitly designed have been mentioned.

Cost and engineering constraints led to the change to EV5, which allows a much shorter mission while still meeting the project's science goals.

Eventually the project was canceled in 2011 for the increased cost and the difficulty of achieving science goals.

What are the main science goals of Webb?

The Integrating-Theme pages describe the science goals, activities and interactions with partners.
