Kosmos 842
1976-070A
Kosmos-842 was launched into an orbit similar to the Parus navigation satellites, but did not transmit navigation telemetry. In the post-Soviet era it was confirmed to be a Sfera geodetic payload.

Explorer 7
1959-009
The S-001A satellite was developed by ABMA and JPL, and transferred to NASA when the agency was formed. It was launched on 1959 Oct 13 at 1530 by a Juno II (Round AM-16A/19A with JPL Cluster 13) from Cape Canaveral into a 101 min, 556 x 1088 km x 50 deg orbit. S-1A, renamed Explorer VII, transmitted until 1961 Feb 17.
The AM-19A launch vehicle was damaged on 1959 Sep 16 when Jupiter AM-23 was destroyed after launch from a nearby pad, but repairs took only two weeks. The Assembly 3 and 4 stages were upgraded structurally to support the heavier payload.
S-1A was a double cone with a short equatorial cylinder. The Van Allen cosmic ray detector was mounted at the top, with the X-ray and Lyman alpha detectors on the upper cone and the heavy nuclei chamber along the central axis. The micrometeorite and heat balance experiments were on the outside of the cylinder. Four 3.6m antennae were deployed around the satellite's ‘equator’.
