ATS 2 was launched from Cape Kennedy, Florida on 6 April I967. The 

 Agena D failed to function for the second ignition resulting in the 

 satellite being inserted into a highly elliptical orbit rather than the 

 planned 11,100 km. (55990 nm. ) circular prograde orbit. An apogee of 

 11,181 km. (6,033 nm. ) and a perigee of I86 km. (101 nm. ) was attained 

 with a period of 220 minutes. The last useful picture taken by the 

 ATS 2 AVCS was from an altitude of 9,i+68 km. (5,109 nm. ) on I9 July I967. 

 The ATS spacecraft transmitters were silenced on 23 October 1967- 



ATS 3 was launched from Cape Kennedy, Florida on 5 November 1967- 

 A geo-synchronous orbit was achieved with an apogee of 35j705 km. (19,266 nm. ) 

 and a perigee of 35 > 330 km. (19,06U nm. ) 



Although the spacecraft was initially positioned at kY° W., it was 

 soon allowed to drift to a position over the Pacific near 95° W. After 

 a few months, the satellite was made to drift back to a position over 

 South America. It is presently (December I968) being moved to 73° W. 



The satellite was scheduled to conduct eleven experiments; the two 

 involving Multicolor Spin Scan Cloud Camera and the Image Dissector 

 Camera Systems are of oceanographic interest.
