  Interim Control Module - Wikipedia, the free encyclopedia
The Interim Control Module (ICM) was a NASA constructed module to serve as a temporary "tug" for the International Space Station in case the ISS Zvezda service module was destroyed or not launched for an extended period of time.
ICM was to launch on board the Space Shuttle, deploy from the Shuttle's cargo bay, and mate with the ISS at the Russian Control Module (called Zarya).
ICM is currently in a caretaker status at NRL's Payload Processing Facility in Washington, D.C., and is being preserved in readiness in case it is needed for future ISS missions.

 Two U.S. Space Tugs Form Backbone of NASA Backup Plan for International Space Station and Zvezda Module
Both the ICM and Propulsion Module are designed to steer the station on a safe course and provide the necessary reboosts to keep it firmly in orbit above Earth.
The $210 million ICM was built by the Naval Research Laboratory in Washington, D.C. It employs the same sort of spacecraft frame structure used for Navy surveillance satellites.
As it stands, the Propulsion Module now is set to be launched in the summer or fall of 2004 with an expected performance life of 10 years.

 ICM
If the module is seriously delayed or is lost during liftoff there will be a huge delay in the construction of the station and worst case scenario, the station may be lost if they can't get a mission to the station in time to raise the orbit.
The module has several 2,2 Kg (5 pound) thrusters reaching out from the ICM body along with a main thruster cappable of producing a force of 50 Kg (110 pounds).
In addition to building several modules for the ISS, the Russians are supposed to supply the station with 7 Progress and 2 Soyuz flights a year.

 Russian Module Brings ISS to Critical Juncture   (Site not responding. Last check: 2007-10-12)
Originally scheduled for early 1998, the Energia Service Module is the first full Russian-funded element of the ISS and the third station element to be launched.
Module launch and docking would also clear the way for launch of the first ISS crew, U.S. astronaut Navy Capt. Bill Shepherd and cosmonauts Yuri Gidzenko and Sergei Krikalev.
But if the Proton launch fails and the Service Module is lost, the ISS assembly flow will be seriously disrupted, forcing the emergency launch next spring of the Naval Research Laboratory Interim Control Module.

 ISS Propulsion Module - Wikipedia, the free encyclopedia
A Propulsion Module would have been needed for ISS altitude maintenance and reboost, debris avoidance maneuvers, attitude control and propellant supply in the event the Zvezda Service Module was not available (launch failure, etc) to the International Space Station.
Zarya FGB holds 5500 kg and the Zvezda Service module holds 860 kg, however, it is generally preferred to keep the main thrusters on Zarya and Zvezda in reserve, as they have finite lifespans.
The Propulsion module, besides being part of the backup plan for if the Service Module was not available, was intended to be an American-owned propulsion system for the station and planned as a late addition.

 Chronology of the ISS development
The inclusion of the Mir-2 core module into the Freedom design would allow early presence of the crew onboard, while the use of Progress cargo ships would provide much cheaper and reliable refueling and supply capabilities for the station, comparing to the use of the Space Shuttle.
The launch of the first element, Zarya control module, was now officially scheduled for November 1997, the assembly was planned to be completed by June 2002.
The European Columbus module was now scheduled for launch during the 7th Shuttle mission after its return to flight, while the elements of the Japanese segment would reach orbit during the eighth, ninth and 12th missions.

But if the module is lost in a launch mishap or because of a catastrophic problem in orbit, completion of the space station would be delayed by at least three years, according to internal NASA planning documents.
NASA's $100 million interim control module, an unmanned propulsion system being built by the Naval Research Laboratory, would be launched next spring, according to the agency's contingency plan, probably in the April 2001 timeframe.
Once the ICM is in place, NASA likely would continue station assembly through the next five shuttle missions while accelerating development of life support systems and a more capable propulsion module to replace the ICM.

For example: The module was not certified to operate in a depressurized environment, and its capability to function in that environment cannot be assured.
In the interim, NASA believes the risk of flight control loss will be mitigated when U. guidance, navigation, and control software is installed on a later assembly flight.
According to NASA officials, these Service Module issues are largely the result of (1) differing manufacturing philosophies, (2) the fact that the Russian hardware is based on designs applied to the Mir station, and (3) the Russian position that its lengthy Mir experience demonstrates the robustness of its design characteristics.

We expect the U.S. Laboratory module and the remaining flight hardware for the first six flights to be delivered to their respective launch sites by the end of 1998.
Development of the Interim Control Module is an example of a prudent additional expenditure, to guard against costly schedule delays evoked by Russian Service Module issues, or, equally importantly, as additional propellant storage/reboost capability later in the assembly sequence following deployment of the Service Module.
It continues to be NASA’s preference to configure the ICM as a propellant storage/reboost module in the outyears and maintain the baseline configuration which includes the Service Module; this remains the least costly and most robust option.
