Satcom 1R w i ll join fi v e other prev ious RCA conmuni cat ions
s a t e l l i t e s already i n orbit. T h e s a t e l l i t e s provide coverage f o r
a l l 50 states and Puerto Rico wi t h t elev i s i on, voice channels and
h i g h speed dat a tra nsmiss ion. Cu rr ently, there are more than
4,000 earth st ati ons wi th d i r e c t access to these spacecraft.
This w i l l be the second launch of a Delta 3924 vehicle. The
three stage Delta vehicle consists of: an extended Long Tank
F i r s t Stage with Rocketdyne RS-27 engine and nine Castor I V
str ap-on s oli d motors for the f i r s t stage; the new improved
Aerojet AJ10-118k second stage; a Thiokol TE-364-4 t h i r d stage
engine. The enti re vehicle is 8 feet (2.4 meters) in diameter
(excluding the strap-on solid motors) and 116 feet in he ig ht
(353.57 m).
McDonnell Douglas Astronautics Corp., Huntington Beach,
Calif., i s t h e prime contractor f o r production a n d launch o f t h e

RCA SATCOM 1R DESCRIPTION
The RCA Satcom 1R replaces the previous RCA Satcom 1com-munications s a t e l l i t e which has completed seven years service.The Satcom 1R thus mai nta ins f u l l ser v ices from t he RCA domesticcommunications s a t e l l i t e system which provides a wide range of
communications s e r v i c e for government and commerical customers ina l l the 50 states and Puerto Rico.
The spacecraft w i l l be placed i n t o a 35,900 km (22,300 mi.)geosynchronous o r b i t by a Delta 3924. With solar panelsdeployed, the s a t e l l i t e spans 4.72 m (15.5 ft.). Without thesolar panels, the spacecr af t main body measures 1.82m (6ft.)across.

LAUNCH OPERATIONS
NASA's John F. Kennedy Space Center is responsible for thepreparation and launch of Delta 3924 which w i l l carry the RCASatcom I R s a t e l l i t e i n t o o r b i t .
iThe Delta f i r s t stage and i n t e r s t a g e ad apter were erected on
Pad B of Complex 17 at t he Cape Canaveral Air Force Station on 'Jan. 31. Du ri ng the f i r s t week of Feb. the nine solid strap-ons o l i d rocket motors were mounted in place areund the base of thef i r s t stage. The f i r s t and second stages were mated on Feb.7.T he i n i t i a l e l e c t r i c a l and mechanical checkout of the v e h i c l etook place on Feb.14, and an e l e c t r i c a l systems test was con-ducted on Feb.25. A gu id ance systems t e s t was performed onMarch 1, and a simulated f l i g h t was conducted on Mar ch 15. Af l i g h t program v e r i f i c a t i o n t e s t is to be conducted a week beforelaunch.
On Mar ch 14, the RCA I R spacecraf t a r r i v e d by t r a i l e r atCape Canaveral Air Force Station and underwent i n i t a l checkout inHangar AE. Apogee kick motor X-rays and other pr epara ti ons wereconduct ed March 14 th rou gh March 18. Checkout of the safe andarm device was performed on March 21. On March 23, propellentswere to be loaded into the spacecraft, the apogee kick motor wasto be i ns t a ll ed , and the safe and arm d e v i c e was to be connected.

T he spacecra ft went to the Delta Spin Test Fa ci li t y on March21 for f i n a l processing. Propellents were loaded int o thespacecraft on March 23, and the spacecraft was mated with theDelta t h i r d stage on March 25. It was moved to the pad on March28 and mated wi th the Delta v e h i c l e , followed by fu nctional
test s. Th e payload f a i r i n g wh ich prot ects th e spacecraft on itsf l i g h t through the atmosphere was i n s t a l l e d March 31.
