Boeing 601
The Boeing 601 (sometimes referred to as the BSS-601, and previously as the HS-601) is a communications satellite bus introduced in 1987 by Hughes Space and Communications Company. The more advanced 601HP derivative (for "high power") was introduced in 1995. Hughes, and the 601 platforms, were acquired by Boeing in 2000.
Design
Structure
The 601 bus is divided into two modules. The first module houses the propulsion system, batteries, and electronics for the bus, and bears launch vehicle loads. The second module contains shelves carrying the communications equipment, payload electronics, and heat pipes. Solar arrays, reflectors, and antenna feeds are mounted to the payload module.
Payload
The standard 601 platform supports up to 48 transponders and provides up to 4,800 watts of power. The 601HP supports up to 60 transponders and provides up to 10,000 watts.
Failures
A significant number of Boeing 601s have experienced failures in orbit, some resulting in complete failure of the satellite.

Ps.77
by: ZaoI cried out to God for help. I cried out to God to hear me. When I was
distressed, I sought theLord. At night I stretched out my and, but I cannot
be comforted.
I remembered you God and I groaned; I mused and my spirit grew
faint. You kept my eys from closing. I was too troubled to speak. I thought
about the former days the years long ago. I remember my songs in the night.
My heart mused and my spirit inquired.. Will the Lord reflect forever?. Will
He never show his favor again. Has this unfailing love vanished forever. Has
his promise failed for all time. Has God forgotten to be merciful. Has the
anger withheld his compassion. Then I thought, 'To this I will appeal-the
years of the right hand of the Most High. I will remember the deeds of the
Lord. Yes I remember Your deedsof long ago. I will meditate on all Your
works, and consider all Your mighty deeds. Your ways oh God are holy. What
God is so great as our God!'
