A joint human-Hath colonisation attempt of the planet Messaline turned into a short war lasting only seven days but many generations of clone soldiers, including Jenny.

In the latter part of this century, Earth was devastated by solar flares, forcing the human inhabitants to place themselves in suspended animation on board the Nerva Beacon, so they could awaken when the planet became inhabitable again. However, due to sabotage by the Wirrn, they did not wake until ten thousand years later. (TV: The Ark in Space)
The Eighth Doctor saved all life on the planet Espero from the Maker, Reo. (PROSE: Halflife)

The placement of events from The Doctor's Daughter in the 61st century is solely based on the assumption that the year 6012 in the New Byzantine calendar actually corresponds with the same year in the modern-day Gregorian calendar, which may or may not be the case.
