Portal Future Wiki

The drop portal is the Military's most famous technology and used to travel around the galaxy.


S.T.A.R. — Simultaneous Transmission And Reception

The transmitting portal does all the work, and the instant when the drop portal dust ring simultaneously exists at both transmission and reception point, stabilizing its own incoming signal.

–narrative, [1]

A drop portal is fired from a ship, because of power issues it creates a portal out of surrounding dust particles. Also because of the amount of power it generate it must not come in contact with solid matter because the energy will focus into a single explosion if it does.

Once a drop portal forms it is simultaneously exists in both the transmitting and receiving area and will only last for 5.13 seconds.


Un-manned probes are sent into a new star system first.

Mapping Probes

"With a totally new star system, the drop portal coordinates are calculated from astronomical observations. There is a risk of some serious errors because you aren't seeing the current state of the star system. You don't want a manned ship arriving in the middle of a planet, so you send an unmanned mapping probe first, aim it somewhere outside the star system, and it does a high speed bounce through collecting some accurate up-to-date information to use in calculating coordinates.."

–Author Janet Edwards, [2]

The probe sends the information back to the military teams via a comm portal.

Planet First Probes

These probes are designed to be used once and then sent into the star to burn up. A survey ship fires up the drop portal and sends the probe through it.

Because of their limited use, they contain minimal equipment, mostly sensors and basic maneuvering capabilities. They also contain a receiving communication ring so that the Planet First teams can communicate with it. The probes sends the data it collects via the communications ring and receives minor instructions.

Manned Exploration

Once the probes have done their jobs, then a manned ship can enter a new system. There is still a big risk as there may be objects that were initially missed or new comets entered the system, this is why only volunteer pilots are sent to map new star systems.

Her voice took on a heavily formal note. “Major Tell Dramis, I must warn you that this assignment will involve using drop portals to reach uncharted star systems that may contain extreme hazards. You are under no pressure to volunteer for this mission, and you may take a reasonable amount of time to consider your decision.”

–General Hiraga to Drago, [3]
