Hyperbola-3

Hyperbola-3’s liquid methane and liquid oxygen tanks will be joined by an intertank section at the launch site because of road transport limitations.

Hyperbola-3’s 5.2-meter-diameter fairing underwent a separation test in November 2025.

Hyperbola-3’s second stage is 11 meters long and 4.2 meters in diameter.

Hyperbola-3’s first flight plan includes a first-stage booster landing attempt.

Hyperbola-3 uses ten JD-2 liquid methane and liquid oxygen engines, with nine on the first stage and one vacuum-optimized engine on the second stage.

iSpace opened a Hyperbola-3 launch vehicle processing and refurbishment facility at the Wenchang Commercial Space Launch Site in October 2025.

The HyperBola-3 test involved a mock-up stage rather than a flight stage.

HyperBola-3 underwent a landing leg test using a stage mock-up.

HyperBola-3 is testing landing legs with a mock-up stage.

The debut flights of the partially reusable Long March 10B and iSpace’s Hyperbola-3 are scheduled on this year’s launch manifest.

While the transporter-erector was at Commercial Launch Pad 2 with the Hyperbola-3 pathfinder, launch site teams tested and upgraded the pad's pistons used to move launch vehicles from horizontal to vertical, doubling the number of pistons from two to four to improve redundancy and weight capacity to support heavier launch vehicles like the Long March 10B.

iSpace will accelerate plans for its reusable launch vehicle Hyperbola-3 and expand production and testing capacities for relevant systems using the new funding.

On February 6, iSpace and Hainan International Commercial Aerospace Launch Co Ltd rehearsed transferring the Hyperbola-3 pathfinder to Commercial Launch Pad 2 at the Wenchang Commercial Space Launch Site, placing it on its transporter-erector, driving it to the pad, and moving it into the launch position with the transporter-erector swinging away.

Hyperbola-3 may be capable of carrying up to 21,500 kilograms to low Earth orbit.

A Hyperbola-3 flight vehicle may not be ready until March.

The first flight date for the partially reusable Hyperbola-3 is not determined.

i-Space completed a series of tests using a full-scale Hyperbola-3 mock-up to validate the launch system at the Hainan commercial launch site.
