Voyager 2's flyby past the planet Neptune in August 1989 is recounted, focusing on its engineering achievements. The failure of its prime receiver only seven months after launch was followed by the failure of a tracking-loop capacitor in its backup receiver. Through clever engineering, that outage proved no more than an inconvenience. Its cameras were meant to work only in ...

We present photoelectron effects on the impedance of electric field antennas used for plasma wave investigations. To illustrate the photoelectron effects, we applied electromagnetic Particle-In-Cell simulation to the self-consistent antenna impedance analysis. We confirmed the formation of a dense photoelectron region around the sunlit surfaces of the antenna and the spacecraft. The dense photoelectrons enhance the real part, and decrease ...

Voyager 2's flyby past the planet Neptune in August 1989 is recounted, focusing on its engineering achievements. The failure of its prime receiver only seven months after launch was followed by the failure of a tracking-loop capacitor in its backup receiver. Through clever engineering, that outage proved no more than an inconvenience. Its cameras were meant to work only in certain modes; en route Voyager's computers were reprogrammed with entirely new manoeuvers to stabilize an image and allow much longer exposures, so that resolution remained as good as in the images of its earlier, better-lit encounters.<<ETX>>
We present photoelectron effects on the impedance of electric field antennas used for plasma wave investigations. To illustrate the photoelectron effects, we applied electromagnetic Particle-In-Cell simulation to the self-consistent antenna impedance analysis. We confirmed the formation of a dense photoelectron region around the sunlit surfaces of the antenna and the spacecraft. The dense photoelectrons enhance the real part, and decrease the absolute value of the imaginary part, of antenna impedance at low frequencies. We also showed that the antenna conductance can be analytically calculated from simulation results of the electron current flowing into or out of the antenna. The antenna impedance in the photoelectron environment is represented by a parallel equivalent circuit consisting of a capacitance and a resistance, which is consistent with empirical knowledge. The results also imply that the impedance varies with the spin of the spacecraft, which causes the variation of the photoelectron density around the antenna.
This chapter describes how the Deep Space 1 (DS1) spacecraft and the Deep Space Network (DSN) ground systems received and transmitted data. The signal to the spacecraft was at X‐band, and the signal to the ground was at X‐band or Ka‐band or both together. The chapter includes descriptions of the DSN systems used for carrier tracking, radiometric data, command transmission, and telemetry reception as DS1 used them through 2001. The telecom subsystem received and demodulated uplink commands, transmits science‐ and engineering‐telemetry data on either an X‐band or a Ka‐band downlink or both, and provided coherent two‐way Doppler and range‐measurement capabilities using the X‐band uplink, and the X‐ or Ka‐band downlink. The metric data assembly (MDA) at the tracking station processed DS1 Doppler data. The operational scenarios describe the major telecom‐subsystem operating modes in the context of supporting specific phases of the mission or major mission activities and modes.
The challenge facing the European aerospace community after 1992, integrating members' individual capabilities into a decisively unified, noncontentious entity, is addressed. The two stellar examples of European cooperation in this area, the European Space Agency (ESA) and Arianespace SA, which builds and launches the Ariane rockets, are examined. ESA is a consortium of the national space research agencies of 13 countries and has overall responsibility for the development of Hermes, France's first manned space vehicle. Arianespace has 52 shareholder companies and research organizations in 11 countries; as the first company of its kind, it has captured more than half the world's commercial spacecraft launch-service business. The aerospace industry's biggest question, namely, what will happen in the defense sector, is discussed, focusing on the restructuring resulting from rising arms costs and changing political realities.<<ETX>>
A method to estimate the total fluence of solar flare neutrons at a spacecraft traveling in the innermost part of the heliosphere (at heliocentric radial distances of <1 AU) is presented. The results of the neutron production and emissivity codes of Hua and Lingenfelter (1987a, 1987b) scaled to one of the largest solar neutron events ever observed at the Earth are used to derive a conservative estimate of the energy spectrum of neutrons emitted from the Sun after a large solar flare. By taking into account the survival probability of a neutron to reach a certain heliocentric distance, we evaluate the observed time-integrated spectrum of solar neutrons as a function of the heliocentric distance of the observer. By considering (1) a working relationship between the soft X-ray class of a flare and the flare's production of solar neutrons, and (2) the number and size of soft X-ray flares that may occur during a mission traveling close to the Sun, we compute an upper limit for the total fluence of solar neutrons at energies >1 MeV, >10 MeV, >100 MeV and >1000 MeV to which such a mission may be exposed. We apply this method to the Solar Probe Plus mission. Although our method gives a conservative estimate of neutron fluxes, the predicted mission-integrated fluence of solar neutrons at Solar Probe Plus is orders of magnitude below that of solar energetic protons.
This chapter describes the deep space network (DSN) as it is today. It includes brief descriptions and functional block diagrams of DSN systems at the Deep Space Communications Complexes that provide carrier tracking, radiometric data (Doppler and ranging) collection, command uplinking, and telemetry reception and decoding for deep space missions, those defined at lunar distances or greater. Delta‐differential one‐way ranging (delta‐DOR) is a very long baseline interferometric (VLBI) radio‐tracking technique using two deep‐space stations located at different complexes for a single measurement. In general, telemetry service support requires one antenna, at least one receiver, and telemetry processing equipment for each spacecraft. The telemetry system performs three main functions: data acquisition, data conditioning and transmission to projects, and telemetry‐system validation. The chapter summarizes the major uplink and downlink characteristics of the stations when operating in the DSN frequency bands.
