	This was the first ‘big’ mission for the GRARR team. It supported the '''trans-lunar injection''' (TLI) of '''IMP-D''' on 1 July 1966 on its way for insertion into orbit around the Moon – years before CRO USB became prime for Apollo trans-lunarnsertion. Although IMP-D failed to go into lunar orbit, it achieved its objectives when inserted by Carnarvon into a very eccentric Earth orbit with apogees from 70 to 135 Earth diameters and perigees of 6 to 44 Earth diameters.

-	The last GRARR track had arrived. CRO had not tracked for nine weeks when Helios-A was launched on 10 November ’74. The vital support of the combined station was flawless during the long process of trans-solar injection of Helios into an extreme elliptical orbit to loop it closely around the Sun before returning to the vicinity of Earth. Data from this joint German-USA mission would be correlated with that from the IMP missions.	+	The last CRO track had arrived.

-	AE-C was launched in December ‘73 into a highly elliptical orbit with a very low perigee dipping into the thermosphere for atmospheric measurements. It carried an on-board thruster to vary the spacecraft’s orbit attitude between 68°N and 60°S and to move the perigee slowly through the various time zones and latitudes. CRO GRARR received an '''‘exceptional support’ TWX''' for its command activity.
