Complaint for Declaratory Judgement
The Eros Project finally proceeds into the United States District Court, District of Nevada. On November 6, 2003, Mr. Gregory W. Nemitz filed documents in Federal Court to demand a determination of his Rights in relation to his property claim for Asteroid 433, Eros. A jury will decide the case.

U.S. Department of State Responds
On August 15, 2003 the United States Department of State responds to the Eros Project and its claims. This official action creates a "case in actual controversy" which
gives a Federal Court jurisdiction to hear the case.

NASA Makes its Final Determination
On January 21, 2003 NASA sends its final determination to OrbDev's invoice for Parking and Storage Fees for the NEAR Shoemaker spacecraft, permanently parked on Eros.

----- The MetroCircus
Also known as a "Nemitz Ring-City", is an improvement on the O’Neill space city concept first developed by Gerard K. O’Neill. The MetroCircus design offers incremental growth and development of space city systems, allowing a learning curve towards building full-fledged O’Neill space cities.

A MetroCircus is a moving train on a circular track. It has no front or back, it’s a seamless circle, or a circular track full of cars. The train may use wheels on the track or be a mag-lev system. The MetroCircus is inside a 1 kilometer diameter circular trench or tunnel in an asteroid or small planet. A train track is placed on the outer wall of the trench or tunnel. The MetroCircus runs on the track, producing simulated gravity by centripetal force. 

One main advantage of this design is that the moving structure does not include the radiation shielding mass. This enables far less massive structures and enables the early development of large-scale habitable structures with simulated gravity on Eros.

The construction method can vary, from multiple cars to a welded construction for a completely solid circle. The hull could be up to several inches thick and made of nickel-iron, or even solid Platinum Group Metals. One kilometer in diameter is large enough to reduce or eliminate debilitating coriolis effects. A one-kilometer MetroCircus would run at about 150 kph to simulate 0.40 gravity.

To get on and off the moving city, another track runs alongside. A ‘commuter bus’ accellerates to match speed with the city, then workers and materials are transferred.

The Eros Project thanks the Artemis Society International, http://www.asi.org, a non-profit research foundation, Gregory Bennett, and Mike Delaney for providing supporting technical analysis and MetroCircus images.
