APP-VENTURES OF A LIFETIME

Adventure-seekers now have an app to help them enjoy once-in-a-lifetime experiences — provided they have the cash to make it happen. The digital concierge service Velocity Black is an invitation-only gateway to excursions that are the stuff of fantasies.

For example, there’s a 10-day mission to the International Space Station; a two-week snow leopard experience in the Trans-Himalayas of Ladakh, India, shown; and a 20-day sailing trip to Antarctica with photographer David Yarrow.

None of those tickle your fancy? Try swimming with orca whales, flying fighter jets or training with Japanese ninjas.

Membership costs US$2,800 per year.
