New Mars

New Mars was a planet in Mutter's Spiral, settled on by the Ice Warriors following the destruction of Mars' climate. The Eighth Doctor once wished to be on New Mars. (PROSE: Seeing I)

According to one account, around the 27th century, the Ice Warrior, Sstac, introduced himself as "Grand Marshall Sstac of New Mars". He said that after Mars became a dead world, his people had "fresh goals and glories on New Mars". Benny responded that she visited the planet and had been meaning to look up old friends there for "years". (AUDIO: The Dance of the Dead) She previously asked the Seventh Doctor if he mentioned New Mars to the Warriors he encountered in 3000. (PROSE: Legacy)

However, the Monk showed Tamsin Drew that the Ice Warriors didn't even find a new world to live on until the discovery of Halcyon around the 33rd century. The Eighth Doctor told the Monk the destruction of Halcyon was "a part of the Web of Time". (AUDIO: The Resurrection of Mars)

New Mars was a member of the Galactic Federation and had a royal family. During the Martian Civil War, the monarch was deposed by Grand Marshall Raxlyr and most of the royal family was murdered. The New Martian Republic had taken control of New Mars, placing it under martial law, and New Mars was isolated from the Federation. Izlyr sent Princess Lixgaar along with the other Martian refugees to Peladon, before she could be safely be transferred to the Federation headquarters on Io. (AUDIO: The Prisoner of Peladon) By the 41st century, Martian royalty started to refer to themselves as princes and princesses "of Mars". (AUDIO: The Bride of Peladon)

In the 347th century, the Slitheen family had tours of New Mars, which showed atrocities caused by humans. (PROSE: The Slitheen Excursion)
