Venera 5
1969-001A
V-69 No. 330 was named Venera-5 after its successful launch. The solar orbit insertion burn was over Africa. The SA stopped transmitting at an altitude of 25 km. It impacted at -3 latitude, 18 longitude. Conditions at the site were calculated to be 530 C, 140 bar.

Surveyor 7
1968-001A
Surveyor SC7 (Surveyor G) was launched at 0630:01, on azimuth 102.9 deg, on 1968 Jan 7 by Atlas Centaur. The Centaur coasted in parking orbit, then reignited and shut down at 0705:16 to deliver Surveyor VII to a translunar trajectory. The Surveyor made a course correction at 2230 on 1968 Jan 7. The radar was jettisoned around 0100 on Jan 10 and the retro fired successfully, with landing at 0105:38 on Jan 10 on the Tycho ejecta blanket. For the first time both the alpha-scatter and sampler experiments were carried on the same mission. The craft returned over 21000 pictures, and survived one lunar night. The surface sampler was tested, manipulating rocks and digging trenches. On the second lunar day, battery degradation limited operations. The last transmission from Surveyor VII was at 0024 on 1968 Feb 21.
