Sind Statistiken über die Zeit verfügbar, die von verschiedenen Raumfahrzeugen für die Kommunikation mit dem NASA Deep Space Network (DSN) verbraucht wird?
Es wäre interessant zu vergleichen, welche Weltraummissionen mehr Downlink-Zeit benötigen. Auch die Kosten für die DSN - Kommunikation sind ungefähr proportional zur verbrauchten Zeit .
Wo sind diese Informationen zu finden?
Ich möchte eine Antwort in Form wie:
"spacecraft 1 - X1 hours in year 2017"
"spacecraft 2 - X2 hours in year 2017"
oder und
"spacecraft 1 - Y1 hours during all the mission's lifetime"
"spacecraft 2 - Y2 hours during all the mission's lifetime"
BEARBEITEN:
Vielleicht befasst sich diese Antwort mit dem Problem, aber ich bin mir nicht sicher.
Ich habe eine FOIA-Anfrage für jeden Kontakt eingereicht, der vom DSN ab 2010 hergestellt wurde (ich habe Kontakte vom 1. Januar 2010 bis zum 1. September 2018 erhalten).
Hier ist eine Zusammenfassung der Kontaktzeit für alle 86 Missionen, die in dieser Zeit vom DSS kontaktiert wurden, sortiert nach Gesamtzeit (in Stunden).
