Spacelab Regula I was a Federation Regula type research station located in orbit of the Class D planetoid, Regula, located in the Mutara sector. Also known as "Marcuslabs" in the 2280s, Regula I was under the direction of Dr. Carol Marcus, whose scientific team were working on Project Genesis.


In 2285, Regula I was raided by Khan Noonien Singh in an attempt to obtain the Genesis device for himself. While the Marcuses and the Genesis research material were transported down to Regula, the other research staff were tortured and killed by Khan as he attempted to discover where the information was witheld. Little did he know that the USS Enterprise would also stop at this base to figure out what happened after the ambush by the USS Reliant. (TOS movie, novelization & comic adaptation: Star Trek II: The Wrath of Khan)

Afterwards, Carol and David Marcus returned to the station. (TOS comic: "The Wormhole Connection")

A few weeks later, Dr. Marcus returned to Regula I, where Admiral James T. Kirk personally informed her of David Marcus' death on the Genesis Planet at the hands of the Klingons. Following this, the USS Excelsior arrived to take Admiral Kirk and his former command staff into custody. (TOS - The Mirror Universe Saga comic: "... Promises to Keep")

Over the course of a century, the station was mostly inactive and received only a few visits from Starfleet researchers on special projects. (Star Trek: Intrepid)

In 2388, Starfleet Command lost contact with Regula I after the USS Columbia was destroyed by a Elachi starship, Vice Admiral Kathryn Janeway sent the USS Intrepid-A and a small fleet to Regula I in the Mutara sector. USS Voyager was part of the fleet. Admiral Janeway came with the fleet aboard Voyager. The fleet got a distress call from the USS Stargazer, it was under attack by Elachi ships.

The fleet sets a course for Regula I using their quantum slipstream drives. Twelve hours later the fleet arrived at Regula I, the fleet engaged the Elachi ships and forced the vessels to retreat from Regula I, and reported the encounter to Starfleet Command. After driving off the Elachi ships from Regula I, Captain Kira lead a away team to the station with Colonel Sarah Mackenzie along with Captain Chakotay, Lieutenant Commander Tom Paris and Lieutenant Kim. (Star Trek: Intrepid)

Soon the away team came under attack by a Human woman armed with a Klingon disruptor pistol. Captain Kira ordered Colonel Mackenzie to use a stun grenade to stun the Human. It was found that the Human woman was Cheryl Anderson, Typhuss's ex-wife and the second woman was a clone of Xena.

The Voyager officers returned to Voyager, Captain Kira ordered Mackenzie back to the ship with the two women and take them to sickbay. Mackenzie beamed back to the ship and later Captain Kira beamed back to the ship. (Star Trek: Intrepid)
