ASTRONAUTICS AND AERONAUTICS, <strong>1967</strong> December 2<br />

problem instead of helping to solve it. . . . The U.F.O. phenomenon is<br />

a challenge to mankind. It is the duty of scientists to take up this chal-<br />

lenge, to disclose the nature of the U.F.O. <strong>and</strong> to establish the scientific<br />

truth.” (Kamm, NYT, 12/10/67, 70)<br />

December 3: U.S.S.R. launched Cosmos CXCIV into orbit with 333-km (207-<br />

mi) apogee, 205-km (127-mi) perigee, 89.7-min period, end 65.7” in-<br />

clination. Equipment <strong>and</strong> instruments functioned satisfactorily, <strong>and</strong><br />

spacecraft was successfully recovered Dee. 11. ( W Post, 12/6/67, B2;<br />

Interavia Air Letter, 12/14/67,6; GSFC SSR, 12/15/67)<br />

“Evaluation of Apollo 4 mission data . . . continues to confirm initial<br />

reports that Spacecraft 017 met all flight objectives without problems,”<br />

NASA announced. Detailed systems analyses were still in process, but<br />

evidence to date indicated spacecraft systems operated properly during<br />

Nov. 9 mission <strong>and</strong> met all specifications.<br />

First Service Propulsion System (SPS) burn had occurred as sched-<br />

uled; second SPS burn, however, was 13 sec longer than planned, because<br />

of a switchover to ground control after burn was started by onboard<br />

guidance <strong>and</strong> navigation system. Although review of the burn was still<br />

being conducted, NASA had already determined that there had been no<br />

failure in onboard systems involved. Because of the longer-than-planned<br />

SPS burn, spacecraft’s reentry velocity was 0.0058% higher than ex-<br />

pected; actual velocity was 24,913 mph, compared with nominal 24,772<br />

mph. Increased velocity caused higher Comm<strong>and</strong> Module (CM) maxi-<br />

mum heat rate-620 BTUS per sq ft per sec instead of planned 586 BTUS.<br />

Maximum rate expected on lunar return was 480 BTUS. Maximum g on<br />

reentry was 7.3, compared with expected 8.33 g, because of a shallower<br />

reentry flight-path angle.<br />

Cabin pressure remained between 5.6 <strong>and</strong> 5.8 psi during entire mis-<br />

sion, indicating negligible leakage rate. Cabin air temperature remained<br />

stable at 60” F during orbit <strong>and</strong> increased to 70’ F during reentry.<br />

Structural performance of the spacecraft <strong>and</strong> Lunar Test Article 10-R<br />

(a simulated lunar module) during launch <strong>and</strong> boost phase was satis-<br />

factory. Earth l<strong>and</strong>ing system functioned as planned; all parachutes in-<br />

flated properly, <strong>and</strong> recovery aids deployed <strong>and</strong> operated normally.<br />

Heat shield performance was good; maximum char thickness was 3/a in,<br />

<strong>and</strong> charring of crew compartment heat shield was less than expected.<br />

Fuel cell <strong>and</strong> cryogenic subsystems functioned normally, with fuel cells<br />

producing potable sterile water <strong>and</strong> demonstrating excellent load-shar-<br />

ing <strong>and</strong> thermal-control capability. CM <strong>and</strong> SM reaction-control systems,<br />

electrical power subsystem, <strong>and</strong> spacecraft sequential devices operated<br />

normally, with all functions occurring at scheduled times.<br />

Guidance <strong>and</strong> control system <strong>and</strong> the mission control programmer<br />

performed properly. Range-to-go at drogue parachute deployment cal-<br />

culated was 2.2 nm. Comparisons with measured l<strong>and</strong>ing point indicated<br />

better than predicted performance. All communications objectives were<br />

accomplished. Each MSFN station, Apollo tracking ship Vanguard, <strong>and</strong><br />

at least two of the Apollo/Range Instrumentation Aircraft established<br />

two-way communications with the spacecraft as planned. (NASA Release<br />

67-294; Hines, W Star, 12/3/67, A20; SBD, 12/5/67, 172-3)<br />

e As of Nov. 15, US. had dropped 1,630,500 bombs on North <strong>and</strong> South<br />

Vietnam since July 1965-twice the tonnage dropped during the<br />

Korean War, <strong>and</strong> three times that dropped in the Pacific Theater during<br />

World War 11. (Wilson, W Post, 1/5/68, 4)<br />
