Deep Space has moved and is now hosted at the Citadel: The Legion Chronicles sim. Thank you Citadel for helping us keep the dream alive!
Everything about Deep Space that you are familiar with has not changed, with the only difference being the absence of an MB3 entry due to the closure of the Space Station. Instead, the main entryway now supports Citadel.
MB3 was our most ambitious project in SL to date and one of the hardest to let go of, for sure. Most of the mesh objects we created for the sim are still available on the SL Marketplace Store, and picture galleries and videos of the sim remain on the website for viewing.
