A U.S. military-backed company plans to deliver a payload to any point on Earth within 90 minutes by prepositioning assets in space and then calling down delivery vehicles as needed. Sierra Space, a subsidiary of the Sierra Nevada Corporation, has successfully completed two test drops of its Ghost reentry vehicle while carrying a bottle of whiskey and a software-defined radio. According to Aviation Week, the test was conducted using high-altitude balloons that dropped it from 35,000 feet and 68,500 feet.

While this test isn’t as exciting as SpaceX rockets landing on a platform at sea, it’s still an achievement for the team working on the project, as it’s the first test of the vehicle in two years. This demonstration is part of the U.S. Space Command’s Apollo Nexus training exercise, which aims to demonstrate the needed synchronization of multiple units in complex operations.

The test’s payload isn’t just two random items, either. They’ve been specifically selected to show that liquids and sensitive electronics could survive part of the trip back to the surface. “We were able to safely demonstrate that and prove that we could come through all of those environments and then be recoverable in a certain period of time by the team on the ground,” Sierra Space senior vice president Erik Daehler told the publication.

It should be noted that these cargo units aren’t designed to be launched by rockets from another side of the world to be delivered to frontline forces as needed. Instead, they’re designed to stay in orbit for up to five years and then be called down to troops as needed — similar to how Orbital Depots drop down from the sky when called by an SCV in StarCraft II.
