Before the Shipyards: The Taming of Phobos

The high porosity of the interior of Phobos (based on the density of 1.88 g/cm³, voids are estimated to comprise 25 to 35 percent of Phobos' volume) is inconsistent with an asteroidal origin.

In 2095AD, Space Exploration Arm Mission, "Falcon's Perch" successfully discovers that Phobos has been systematically mined by another space-faring civilization. Ship archeologists and planetologists conclude in several lengthy reports to the International Space Agency that some bioforms were discovered... The survivors of the mission are ordered to Mars' Alpha-One headquarters.

Dateline 2096AD: The Republic of Mars loses contact with a surface garrison base on Phobos. Grand Marshall Marquis Hector de la Vasquez offers a reward of ten million Imperial Credits (9.8Billion USD c.2012)to any private mercenary group or traveller capable of penetrating the base on Phobos and reporting upon the status of the missing troops...

Warp Drive Technology

This type of FTL drive is sometimes possible in a standard Traveller universe, but usually at very high tech. levels (like 17+).

Other aliens or other humans from alternate universes can sometimes develop this earlier (with all the attendant social ramifications). The following adaptation of this technology has been brought into the OTU by Prof. MacDougal via his time machine/probability ship.

Warp Drive
Size: 10%HV
Cost: 2Mcr./dt size
Energy: EP=size drive size in dt / (Perf. rating*10)
{TL16/100dt vessel: 10dt, 10EP, 24McrImp.}
{TL15/100dt vessel: 10dt, 25EP, 20McrImp.}
{TL14/100dt vessel: 10dt, 34EP, 19McrImp.}
{TL13/100dt vessel: 10dt, 50EP, 18McrImp.}
{TL12/100dt vessel: 10dt, 100EP, 17McrImp.}
{TL9-11/100dt vessel: 10dt, 168EP, 14,15,16McrImp.}
Performance:
TL17: 1psc/hr.
TL16: 0.1psc/hr. (2.40psc/day; 16.8psc/week)
TL15: 0.04psc/hr. (6.72psc/week)
TL14: 0.03psc/hr. (5.04psc/week)
TL13: 0.02psc/hr. (3.36psc/week)
TL12: 0.01psc/hr. (1.68psc/week)
TL9-11: 0.006psc/hr. (1.01psc/week)

{Thus the higher technology the drive, the less energy it requires to maintain warp at FTL speeds.}

High Energy Reaction Drives

Alternative high energy reaction drives (values per G of thrust)

{Gravitic drive included for comparison}
