 Engineers attaching the shuttle Discovery to its external fuel tank ran into problems Friday when an internal nut used to attach a separation bolt to the belly of the orbiter slipped out of position.

Dark adaption 3

The perfect astrotorch puts out a pure red beam that is dim enough not to harm dark adaptation.

A too-bright red light can be nearly as harmful to night vision as a white light.

Get one with a strap, a dimmer control, and a sturdy housing
