Sputnik 2
1957-002
After the success of the first satellite, a second PS was built with a small pressurized cabin. The 508 kg PS-2 was launched on Nov 3 into a more elliptical orbit, becoming satellite 1957 Beta. It remained attached to the 7380 kg rocket stage so that it could use the telemetry system of the rocket and to prevent overheating of the cabin. PS-2 consisted of a solar UV/X-ray detector package, a PS-1 sphere with pressure and temperature sensors, and the 0.8m long 0.64m diameter dog container derived from a suborbital R-2A launch design. Inside the cabin was a dog called Laika, the first space traveller. Laika (reportedly originally called Kudryavka) was a 6 kg, two year old female. PS-2, the second ISZ , also carried a radiation detector and a detector to measure the flux of X-rays and UV radiation from the Sun. It reentered and burned up in the atmosphere on 1958 Apr 14 over the Atlantic near the coast of Surinam.

ESRO 1A
1968-084A
The ESRO IA satellite was developed by the Laboratoire Central de Telecommunications to study polar ionospheric and auroral phenomena. It was launched in Oct 1968 by a NASA Scout into polar orbit. Control by ESTRAC. Mass 85 kg.
The satellite was 0.76m dia 0.93m high cylinder, 1.53m high including the boom; 2.43m span across antennae. Two 0.1 kg yo-yo weights on 4.5m wires were ejected.

Saturn S-IVB-511
1972-031B
SA-511 was launched on 1972 Apr 16 at 1754 UTC.
After CSM sep, the LH2 dump was nonpropulsive. The LOX dump Apr 16 at 2233 UTC to 2234 UTC gave an 8m/s velocity change.
The S-IVB-511 stage impacted the lunar surface at 2102:04 on Apr 19 at location 2.1N 22.1W with velocity of 2.655 km/s at an impact angle of 16.6 deg.

Explorer 13
1961-022
The second in the series, S-055A, reached orbit on 1961 Aug 25. Ascent was at an 80 degree elevation and 90 deg (eastward) azimuth. However, the orbit was lower than planned, 125 x 1164 km x 37.7 deg, due to a large injection angle error. (TN-D-1396 indicates initial perigee was 139 km, with an injection angle of -4.396 degrees; injection altitude was 455.6 km, so injection velocity was around 7.748 km/s).
The S-55 satellite was attached to the Altair X-248-A5 stage and a set of pressurized cells was installed around the rocket stage. Mass was 57 kg payload; 86 kg including the 22 kg empty Altair and upper 'D' Scout section, which was 6 kg. Size was 1.93m long 0.58m dia. LaRC managed the project, with detectors from LaRC, LeRC and GSFC.
