Phase 2 of Project Rover became called Phoebus, and Phase 3 was known as Pewee, demonstrating much higher power ( 4000 MW ), power density and long-lived fuels, but these programs did not make their way to NERVA.

Later designs were deemed by NASA to be usable for space exploration and Los Alamos felt that it had cured the last of the materials problems with the untested Pewee.

Without the Saturn S-N rocket to carry the NERVA to orbit, Los Alamos continued the Rover Program for a few more years with Pewee and the Nuclear Furnace, but it was disbanded by 1972.

The United States tested twenty different sizes and designs during Project Rover and NASA's NERVA program from 1959 through 1972 at the Nevada Test Site, designated Kiwi, Phoebus, NRX / EST, NRX / XE, Pewee, Pewee 2 and the Nuclear Furnace, with progressively higher power densities culminating in the Pewee ( 1970 ) and Pewee 2.

Current ( 2010 ) 25, 000 pound-thrust reference designs ( NERVA-Derivative Rockets, or NDRs ) are based on the Pewee, and have specific impulses of 925 seconds.

Four basic designs came from this project: KIWI, Phoebus, Pewee and the Nuclear Furnace.

Virtually all space mission plans that use nuclear thermal rockets use derivative designs from the NERVA NRX or Pewee.

Working NERVA designs ( termed NERVA NRX ) were based on KIWI ; by the time Pewee started testing the Apollo program had largely been defunded by the Nixon administration.

It was fired several times at 500 MW in order to test coatings made of zirconium carbide ( instead of niobium carbide ) but Pewee also increased the power density of the system.

Pewee Valley is located at ( 38. 309552 ,-85. 489137 ).

The larger NERVA I rocket gradually gave way to the smaller NERVA II rocket in mission plans as efficiency increased and thrust-to-weight ratios grew, and the KIWI gradually gave way at Los Alamos to the smaller Pewee and Pewee 2 as funding was cut to lower and lower levels by Congress and the Nixon administration.

Tests of the improved Pewee 2 design were cancelled in 1970 in favor of the lower-cost Nuclear Furnace ( NF-1 ), and the U. S. nuclear rocket program officially ended in spring of 1973.

A smaller version of KIWI, the Pewee was also built.

Pewee 2's fuel elements reduced fuel corrosion still further, by a factor of 3 in Nuclear Furnace testing, but Pewee 2 was never tested on the stand.
