Sierra Space Drops Ghost Reentry Vehicle From 68,500 Feet in Orbital Delivery Test

Sierra Space demonstrated the flight recovery capabilities of its Ghost reentry vehicle on October 11, 2026, dropping a 10-ton test article from high-altitude balloons over Utah. The test validated the structural thermal protection and precision landing guidance behind a concept designed to deliver cargo anywhere on Earth within 90 minutes.

The demonstration took place under U.S. Space Command's Apollo Nexus exercise at the Dugway Proving Ground. It marks the latest milestone for the logistics platform, building on the original unveiling of the Ghost vehicle under the Axelerator program and the subsequent launch of the Sierra Space Defense operational unit. The work supports the Department of Defense's Tactically Responsive Space framework, which is evaluating space-based point-to-point delivery as an alternative to conventional air mobility or sealift in contested operational theaters.

Dropped from 68,500 feet, the test vehicle executed automated shield jettison following terminal atmospheric entry, then deployed a steerable parafoil system. The autonomous parafoil guided the payload module to a touchdown within 100 meters of the targeted landing zone. The internal payload, comprising a software-defined radio and a bottle of whiskey, was recovered intact.

The Ghost platform uses a deployable decelerator thermal shield designed to withstand reentry temperatures up to 2,000 degrees Fahrenheit, or 1,093 degrees Celsius. Built for 5- to 10-ton cargo capacities, the capsule can be pre-positioned in low Earth orbit for up to five years as an on-orbit emergency supply repository. Upon receiving a deorbit call-up signal, onboard thrusters slow the vehicle to 7,000 meters per second to initiate reentry, delivering supplies to contested or austere ground locations anywhere on Earth within 90 minutes.

The demonstration puts hardware through recovery testing tied to a named Space Command program, advancing the military-backed orbital logistics concept toward operational demonstration. The framework it supports is assessing whether cargo delivery from orbit can serve as an alternative to aircraft or sealift in contested theaters.

Following the balloon drop tests, Sierra Space plans to advance the Ghost platform toward full-scale suborbital and orbital flight tests. Future phases will evaluate autonomous rendezvous, orbital deorbit firing, and high-velocity atmospheric reentry from low Earth orbit ahead of potential operational deployment with military logistics units.
