Surveyor Lunar Lander 1966-1968 (Boeing - NASA)

Description

Four decades ago the United States and NASA perfected "terminal descent" and the art of landing safely on Earth's Moon. Nothing fancy, Surveyor showed us a lunar surface familar now but unexpected in 1966, and hinted at a Moon selenologists still haven't figured out. Competing for Google's Lunar X-Prize? Read how they made it look easy.

Each is capable of operating in either a high-power or a low-power mode in accordance with the bandwidth of the transmitted data. A signal processing system transforms television and engineering data signals into a form suitable for modulating the transmitter. Highly accurate tracking of the spacecraft is obtained by spacecraft transponders that permit two-way doppler shift measurements. In this mode, one of the transmitters is phase-locked to one of the receivers through transponder interconnection circuitry, and the signal transmitted back to Earth is coherent with the received signal. Two transponder interconnection units are used for reliability. There are three telecommunications antennas aboard the spacecraft: a high-gain directional antenna, the planar array, used only for transmission; and two omnidirectional conical antennas. The planar array orientation, with respect to the vehicle, is controlled by Earth commands. Each of the omnidirectional antennas is permanently connected through a diplexer to one of the spacecraft receivers. The omnidirectional antennas are positioned so that commands can be received regardless of spacecraft attitude. The spacecraft derives its electrical batteries. The solar panel furnishes charging during transit and the lunar 1000-ampere-hour periods of peak load power from a solar panel and power for functional use and day.

Some time before the sustainer and vernier engines burn out, commands from the Centaur programmer will initiate ejection of the Centaur insulation panels and the spacecraft nose fairing. After sustainer and vernier engine burnout, the Centaur separates from the Atlas. The Centaur engines then ignite, drive the vehicle on into the transit trajectory, and cut off. The Centaur programmer commands extension of the spacecraft landing legs and the omnidirectional antennas and finally, separation of the spacecraft and Centaur.

This maneuver tracking information supplied by the As the first step in the terminal will be executed approximately 15 hours a trajectory terminating at the desired will be computed at JPL, Pasadena, DSIF. the spacecraft roll axis is maneuver, aligned along the velocity vector and the high-gain antenna is aligned toward Earth. Television viewing of the lunar surface begins about 10 minutes before impact. All radars are turned on approximately five minutes before predicted impact. Following a "command enabling" signal to the trigger radar, the landing sequence is automatic. At a slant range of approximately 50 miles from the Moon, the vernier control engines and the main retro-engine are ignited. The retro-engine separates from the spacecraft after burnout at a nominal lunar altitude of 30,000 feet. The vernier engines then operate under control of the doppler radar and the precision altimeter radar so as to slow the spacecraft velocity to about 5 feet per second at a 13-foot altitude. At this time, the vernier engines shut off, and the spacecraft free-falls to the surface. The solar panel and planar array will be unlocked and properly oriented after landing. The post-touchdown condition of the spacecraft will be evaluated by sampling all modes of engineering data, and by attempting to manipulate spacecraft mechanisms. Television survey sequences will then be directed by ground commands. The landing is planned to occur in a region near the Moon's the angle between the unbraked, approach velocity vector and the tical is approximately zero degrees. The spacecraft design provides capabilities for approach angles to 45 degrees with respect to the vertical; thus, landings can be accomplished in other maria in the of the face of the Moon as shown in Figure I-4.

This system Eastern Test Range (AFETR), the Deep Space Instrumenand the Space Flight Operations Facility (SFOF), all of Section II. Data from AFETR will be obtained from before launch until after spacecraft/launch vehicle separation. This data will provide the information necessary for spacecraft acquisition by the DSIF stations, for computation of the preliminary spacecraft trajectory, and for preliminary evaluation of spacecraft performance. Data that is obtained from the DSIF will be used for real time monitoring of spacecraft performance and status, for near-real time spacecraft performance and flight path analysis, and for determining spacecraft and flight path commands. This data is transmitted from AFETR and the DSIF to the SFOF where computational the SFOF. processing comprises the major effort in data handling by The nature of Surveyor space flight operations is such that the flow of data in real time is of prime concern. Figure III-1 indicates the types of data that will be obtained during the flights and the types of communications links over which this data may flow from AFETR and the DSIF to the SFOF. It may be seen in Figure III-1 that varied communications capabilities exist for transmitting data to the SFOF; however, this figure does not show specific line assignments or the number of lines available. Each type of data may be traced to its user in the SFOF. Figure ILI-2 details the flow of data from the SFOF to the DSIF. This data comprises spacecraft commands, antenna pointing angles, and administrative information. As in Figure LII-1, this figure does not attempt to indicate information on-line assignments and priorities. C.

Command transmitted to the spacecraft as a binary wavetrain, frequency subcarrier that, in turn, phase modulates the DSIF transmitter. craft receiver recovers the binary wavetrain and routes it to mand decoder. The basic command word is 24 bits in length. Two types of commands are transmitted to the spacecraft: direct and quantitative. (The command word formats are shown in Figure IV-1. Tables IV-I through IV-VIII list direct command words and the proper spacecraft responses.) Direct Commands, most of which initiate some action by the spacecraft, are identified by a four-digit octal number. The centra-r-_-_ecoder routes an ordinary command to the subsystem decoder signified by the first two digits of its octal identification. The subsystem decoder then initiates the spacecraft response called out by the last two digits of the octal command number. A Quantitative Command establishes the length of time over which a spacecraft action initiated by a subsequent Direct Command shall occur. Quantitative Commands are routed by the central command decoder to the flight control subsystem decoder for decoding and storage.

Deep Handling Space Instrumentation (C'DC) Facility (DSIF) and Command and Data Console Generation of the command signal that modulates the DSIF transmitter (the modulated subcarrier) is accomplished by the command subsystem of the GDC. Command words are entered in a ten-bit register in the GDC by sequentially depressing four of a set of octal keys, or through a punched mylar tape reader from tapes prepared before the mission or generated from TTY transmission during the mission. The octal command number (or magnitude) is, at this time, displayed on the console for operator examination. In the keyboard entry mode a "transmit" button initiates sequential readout of the register contents to modulate the SCO.

GENERAL Section V presents, on a certain prescribed level, the normal, or standard, sequence of events. It is recognized that deviations from this standard will occur; therefore, every effort must be made to define various failure modes in anticipation of such events. Several representative situations are included in this Section with a discussion of the methods by which these situations would be handled operationally. B. NONSTANDARD The nonstandard classified as: Prepared Corrective Nonprepared Corrective encountered. A criticalness Class Class Class Class The classification sequences further of A B C D number is action will be determined at the time these situations are action will be available.

USE OF FAULT ISOLATION TREES The Nonstandard Procedures are to serve as the mechanism of operations control during the analysis of spacecraft failures, within the limitations imposed by the assumption of single faults. SPAC has the primary responsibility for the required interpretation of spacecraft data and determination of command decisions. If the single fault limitation does not hold, SPAC may intermesh certain applicable trees, and use any additional techniques necessary to isolate the faults in order to arrive at a satisfactory recommended course of action. The DSIF will use preprepared command tapes according to Detailed Operating Procedures (DOPs), where necessary, in support of SPAC, as directed by Mission Control. When deviations from the standard sequence occur, and anticipated nonstandard procedures exist, the SFOD will direct SPAC to proceed in accordance with the applicable fault isolation tree. A representative tree is shown in Figure VI-1. It should be noted that command sequences are identified by the sequence number associated with the commands on the nonstandard command tape. Corresponding DOP item numbers are given to allow fast cross-reference between the tree and the DOP, primarily for use by DSIF personnel. Branch result of the are developed plished within D. GENERAL choice within a tree is determined by the conditions existing as a fault and as indicated by the current spacecraft telemetry. All trees so that return to the Standard Sequence of Events may be accoma minimum time. NONSTANDARD OPERATIONS PROCEDURES in nonstandard of the Command spacecraft System situations Alternatives The execution of commands required will generally be implemented through one described in Section IV. For nonstandard Classes A and will be grouped on preprepared of commands in these situations mands cution B, above, the required spacecraft CDC command tapes at the DSIF. will be according to Alternative be formulated and transmitted comExeNo. 1. at to the the For nonstandard Class C, the required commands can SFOF manually, or by means of the SCP/CVT program, DSIF via TTY {Command System Alternative No. Z). Execution of commands in nonstandard Class D (Nonprepared, Time ical} will be negotiated in the framework of Aiternative No. 3. Comn:ands be entered on the CDC keyboard, as directed, by voice from the SFOF. Critwill VI-3 EPD-180, | REVISION 1 i ,i I_i I--i!E ii;ll_ t @-t !-_ !': :.i!i! i II|I !
