Mutual Exploration Network
Interstellar Expeditions was once a disorganised collective of hobbyists and academics backed by the idle wealthy investigating mysteries such as the fate of the Minnesota Tribe. However Interstellar Expeditions has emerged from the Jihad to take up the mission once claimed by ComStar's Explorer Corps: to search for the elusive hiding places where humanity's enemies might have gone. From the dead worlds on the borders of the Inner Sphere itself, to the distant, uncharted reaches of the Deep Periphery.

The origins of Interstellar Expeditions lie in the merger of two wildly different groups of archaeologists, historians and anthropologists from across the Inner Sphere; the Star Group and Mutual Exploration Network (MEN).  
The Star Group, itself formed from the merger of the Millennium Foundation and the Federation of Star Lookers in 2889, specialized in mounting archaeological expeditions for universities and museums. While initially widely respected, as the Third Succession War dragged on and research funding dried up, the Star Group was increasingly forced to turn to fortune hunting to remain viable, darkening its reputation as "mercenary archeologists" whose ethics could be bought, with a number of its members engaged in blatant treasure hunting. When the bulk of its more respectable academics chose to leave in 2968 in response to this direction, the Star Group considered disbanding entirely until they were approached by the Mutual Exploration Network. 
Founded in 2894, unlike the academically respected Star Group, the MEN was an entirely amateur organization of wealthy spendthrifts, conspiracy theorists and archaeological hobbyists whose only stated goal was to discover the truth behind the great mysteries of the universe, ranging from the fate of the Minnesota Tribe to seeking out the Greys, alien abductors who supposedly plagued twentieth century Terra. Much of the remaining members of the Star Group expressed concern that the goals of both groups were too divergent, but in truth both sides complemented the other, the Star Group offering the organizational leadership and academic credentials that more amateur MEN lacked, while MEN was provided the funding the Star Group desperately needed, with Interstellar Expeditions born in 2974. The new entity proved far stronger than its component parts and quickly mounted a number of highly successful expeditions.
