The second stage then fired to circularize the orbit, after which it released the satellite and, using its attitude control jets, began a retrograde maneuver to enter a lower orbit to avoid any possibility of collision with its payload. </p><p>In addition to the communication and reconnaissance missions described above, which placed the payload into stationary (24-hour) orbit, the IUS was also used to boost spacecraft towards planetary trajectories. For these missions, the second IUS stage was separated and ignited immediately after first stage burnout. Igniting the second stage at low altitude (and thus, high orbital speed) provided the extra velocity the spacecraft needed to escape from Earth orbit (see <a href="/wiki/Oberth_effect" title="Oberth effect">Oberth effect</a>). IUS could not impart as much velocity to its payload as Centaur would have been able to: while Centaur could have launched Galileo directly on a two-year trip to Jupiter, the IUS required a six-year

The first stage of the two-stage rocket was capable of launching medium-sized payloads at most. This limitation would be overcome by means of the addition of a second stage for larger payloads with destinations into deeper space. Specifically, the Air Force asked NASA to develop an additional stage that could be used for planetary missions such as a proposed probe to Jupiter called Galileo.</q></cite><span title="ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&amp;rft.genre=unknown&amp;rft.jtitle=nasa.gov&amp;rft.atitle=Taming+liquid+hydrogen+%3A+the+Centaur+upper+stage+rocket&amp;rft.pages=172&amp;rft.au=Virginia+Dawson&amp;rft.au=Mark+Bowles&amp;rft_id=https%3A%2F%2Fhistory.nasa.gov%2FSP-4230.pdf&amp;rfr_id=info%3Asid%2Fen.wikipedia.org%3AInertial+Upper+Stage" class="Z3988"></span></span> </li> <li id="cite_note-6"><span class="mw-cite-backlink"><b><a href="#cite_ref-6">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite class="citation web cs1"><a rel="nofollow" class="external text" href="https://www.globalsecurity.org/space/systems/t4-config-2b.htm">"Titan IV Inertial Upper Stage (IUS)"</a>. <i>www.globalsecurity.org</i><span class="reference-accessdate">.

It consists of an aft skirt; an aft stage solid rocket motor (SRM) containing approximately 21,400 lb. of propellant and generating approximately 42,000 lb. of thrust; an interstage; a forward stage SRM with 6,000 lb. of propellant generating approximately 18,000 lb. of thrust; and an equipment support section. - The equipment support section contains the avionics, which provide guidance, navigation, control, telemetry, command and data management, reaction control and electrical power. All mission-critical components of the avionics system, along with thrust vector actuators, reaction control thrusters, motor igniter and pyrotechnic stage separation equipment are redundant to assure better than 98 percent reliability. - The IUS two-stage vehicle uses both a large and small SRM. These motors employ movable nozzles for thrust vector control. The nozzles provide up to 4 degrees of steering on the large motor and 7 degrees on the small motor. The large motor is the longest thrusting duration SRM ever developed for space, with the capability to thrust as long as 150 seconds. Mission requirements and constraints (such as weight) can be met by tailoring the amount of propellant carried.</q></cite><span title="ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&amp;rft.genre=unknown&amp;rft.btitle=STS-30+PRESS+KIT&amp;rft.date=1989-04&amp;rft_id=https%3A%2F%2Fscience.ksc.nasa.gov%2Fshuttle%2Fmissions%2Fsts-30%2Fsts-30-press-kit.txt&amp;rfr_id=info%3Asid%2Fen.wikipedia.org%3AInertial+Upper+Stage" class="Z3988"></span></span> </li> <li id="cite_note-10"><span class="mw-cite-backlink"><b><a href="#cite_ref-10">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite id="CITEREFVirginia_DawsonMark_Bowles" class="citation web cs1">Virginia Dawson; Mark Bowles. <a rel="nofollow" class="external text" href="https://history.nasa.gov/SP-4230.pdf">"Taming liquid hydrogen&#160;: the Centaur upper stage rocket"</a> <span class="cs1-format">(PDF)</span>. <i>nasa.gov</i>. p.&#160;211<span class="reference-accessdate">.
