NASA's tricky task of building a spacecraft to withstand Mercury's extreme environment..

Molt is defined as the routine loss and replacement of feathers. It can occur at any time of year, but in most birds a complete molt occurs in late summer and fall and a partial molt may occur in early spring. The timing of each molt is important. In late summer and fall, there is generally an abundance of insects, seeds, and fruit that provides the energy for molt. This molt provides birds with fresh plumage and often colors and patterns that help conceal it in winter environments.

We’ll explore the comprehensive study’s findings and recommendations.
