system earlier described in the '357 patent, in which those thrusters serve as a companion to the high thrust apogee kick rocket engine. For one, the substitution reduces propellant weight and thereby increases the payload size carried on a mission.
Despite the apparent advantage of the dual mode SCAT engine, Monopropellant rockets, such as the wide range of catalytic thrusters available today in the industry, despite their lower performance, remain the engine of choice for station keeping and attitude control functions in satellite systems. The designs of those monopropellant rockets are space proven; its performance is predictable, it has been reliable; and it offers none of the uncertainty of a new product for the satellite designer. Those advantages apparently outweighed the superior performance offered by the SCAT thrusters. Theof easy, high-speed access to would help keep inner city New Orleans energized and vibrant.

But when the state built the elevated 3.9-mile highway in the 1960s through the Claiborne Avenue corridor — a black commercial district described in reports, books and other publications as once being lively and lined with oaks — the end result was a decaying community.

Fumes and noise of cars moving swiftly down an elevated highway replaced shops and homes there.

Families and businesses left.

Claiborne Avenue had 132 registered businesses in 1960, according to the 2010 study. There were 114 in 1965 and 64 registered businesses in 1971. By 2000, only 35 businesses were located along the corridor.

The oak trees were replaced with the interstate’s concrete columns, now painted with images of the same in a
