KH-8 flight 4303 was launched on 1966 Dec 14 by Titan 3B Agena D from Vandenberg. The spacecraft entered a 138 x 368 km x 110 degree orbit, parameters which would remain typical of KH-8 missions for a decade. The orbit was lowered during the 8-day primary flight. The Agena was deorbited after 10 days.

Denpa
1972-064A
ISAS's Radio Exploration Satellite (REXS) was launched in 1972 and renamed Denpa (Radio wave). It studied the ionosphere and lower magnetosphere but failed after 3 days. Switch on of the EBA caused electrical discharges which toasted the spacecraft encoder. The radio beacon continued to operate until May 1973. REXS was a 70 kg, octagonal cylinder 0.68 h 0.71 dia with three 2m antennas.
M-4S-2 Mass of stage 4 plus payload is 525 f 145 em. Prop mas 380 kg. Payload mass 75 kg implying M-40 is 450f 70 em. Isp 276.0s?

However, it operated until 1976 Jan 29 when its power supply failed, disabling the solar arrays. The satellite reentered on 1976 Mar 12.
Mass was 674 kg with 168 kg prop.
The MRMU released neon gas to simulate outgassing, and the returning gas was measured by NACE, PSA and PSB to study self-contamination.

The San Marco C2 satellite repeated the San Marco C program. The 0.71m dia 176 kg spherical satellite had four 0.49m antennae on the top for a total height of around 1.0m. It was named San Marco 4 after launch in Feb 1974. The orbit was slightly higher than planned, with an apogee of 930 km instead of 850. However, the drag balance experiment did not work correctly after launch.
The Italian Space Commission (Commisione per le Richerche Spaziali, CRS) signed a memorandum of understanding with NASA for the launch; CRA (Centro Ricerche Aerospaziali) managed the project. Command was from MITS, the Mobile Italian Telemetry Station in Kenya.

Mission 9045 was the second low inclination (65 degree) flight, also targeted to Kamchatka. It was launched on 1962 Sep 29 by Thor Agena D from Vandenberg. Agena 1154 orbital mass was 1276 kg. This mission marked the first use of the stellar camera. Spacecraft 1154 suffered from attitude control problems, and numerous camera light leaks. The SRV was recovered after 3 days on rev 48 in an airborne recovery. The lifeboat mode was used to recover the SRV because of the stability problems.

Gambit 19
1965-050B
KH-7 19 was launched on 1965 Jun 25 by Atlas Agena D from Vandenberg into a 151 x 283 km x 107.6 deg orbit. Shortly after orbit insertion it ejected an electronic intelligence subsatellite. For some reason (probably administrative error) this subsatellite was given the earlier catalog number and the 1965-50A international designation, while the main payload got the 50B designation. A second object, 1965-50D, was tracked in the same orbit as the subsatellite but decayed more quickly.

Gambit-3 45
1975-098A
KH-8 no. 45 was launched on 1975 Oct 9 by Titan 23B Agena D from Vandenberg into a new type of orbit: 125 x 356 km x 96.4 degrees. The perigee was 10 km lower than previous missions in the 1970s the apogee 50 km lower, and the inclination reverted to the 96 degrees used by the Atlas Agena flights of the 1960s. This new inclination would be used by the remainder of the GAMBIT series and the low perigee would also become the norm.

DAPP 1963
1963-005A
The third P35 launch used the Scout X-3M, which replaced the Algol 1D first stage with an uprated Algol 2A. The launch on 1963 Feb 19 was successful, although the orbit was 510 x 789 km x 100 deg instead of the planned 734 x 870 km x 98 deg. Each of the first three stages underperformed, with the third stage (Antares) particularly poor. The departure from sun-synchronous orbit made reorientation necessary after several months. The satellite was known as Operation 0240; the P35 program name had changed in Oct 1962. There are indications it was the fourth spacecraft produced, and the 4 in 0240 may refer to this.
Spacecraft 0240 carried an IR detector from the University of Wisconsin as a secondary payload, used to provide nighttime cloud cover maps. This later became a standard instrument for DMSP. 0240 was the first P35 satellite to be operated by USAF ground stations.

Mars 2
1971-045A
The first of the new generation planetary probes to leave Earth orbit was M-71 (3M) No. 171, launched in May 1971. It was named Mars-2.
Mars-2 released its landing capsule on Nov 27 and then entered Mars orbit. It operated for almost a year.

The Mars-2 Spuskaemiy Apparat (Mars-2 Descent Craft) separated from the Mars-2 orbital module on 1971 Nov 27 during its approach to the Red Planet.
The SA separates from the OB. The TDU (braking engine) ignites, sending the SA on an entry trajectory. The SA orients to put the TE (teplovoy ekran, heat shield) forwards. The DU separates. After entry, parachute deploys and TE separates. When the altimeter indicates 20m, the DMP (solid fuel soft landing engine) is deployed on the main parachute. After landing, the upper heatshield is jettisoned and the four petals open to reveal the camera.
SA entry speed is 5.80 km/s. Mass of the SA is 358 kg at landing.
In this case, a software error caused an incorrect braking burn and the pericenter was too small, causing a steep reentry angle and impact prior to parachute deployment.
