Underwater environments simulate the conditions of space exploration and allow NASA to test equipment, perform research, and prepare for future missions in extreme settings such as the moon or Mars. Being underwater replicates the isolation, confined spaces, and limited resources astronauts experience in space.
I always get DAN Trip Insurance for overseas trips, which gives me peace of mind should the unexpected happen. There is a modest upfront payment based on the total trip costs and your age, so I considered skipping it for a Raja Ampat trip since I’ve had many trips without having to file a claim.

A lifetime’s worth of superb diving awaits adventurous divers in the cool, current-swept waters surrounding British Columbia’s Vancouver Island.
Water aerobics can be beneficial for divers who want to improve their control and stamina underwater while minimizing impact on their joints. These targeted water aerobics exercises utilize aqua dumbbells and focus on enhancing a diver’s core stability, strength, and endurance.
Most flights are uneventful, with the worst experiences being an occupied lavatory or unexpected turbulence. Emergencies can happen, however, and aircraft passengers need to be prepared to react quickly and efficiently.

DAN has introduced the Research Grant Program, designed to push the boundaries of dive safety through innovative research. The program will support studies that develop robust theories and empirical evidence that contribute to safer dive experiences.
Any child predisposed to a love of nature will likely find their way to natural environments, which happened early and fortuitously for Linden Wolbert. When she turned 1 year old, her family moved to an old farm in Pennsylvania, not far from where George Washington crossed the Delaware River during the Revolutionary War.
