\label{sec:mission}
|
|
|
|
This section contains the \ac{ATHENA} mission lifetime and storage requirements.
|
|
|
|
\subsection*{R-AHEPaM-012: In-orbit lifetime}
|
|
\label{req:R-012}
|
|
The \ac{AHEPaM} shall be compatible with an overall in-orbit lifetime of 4.25\,years.
|
|
|
|
\paragraph{Justification:} ConOps part B MBD [DDF\_1.0]
|
|
|
|
\paragraph{Verification:} Design/Analysis
|
|
|
|
\paragraph{Comments:} Four years nominal mission plus 3\,months for \ac{LEOP}, transfer, and commissioning.
|
|
|
|
\paragraph{CAU Response:} OK
|
|
|
|
\subsection*{G-AHEPaM-011: In-orbit lifetime}
|
|
\label{req:G-011}
|
|
The \acs{AHEPaM} should be compatible with an overall in-orbit lifetime of 5.25\,years.
|
|
|
|
\paragraph{Justification:} ConOps part B MBD [DDF\_1.0]
|
|
|
|
\paragraph{Verification:} Design/Analysis
|
|
|
|
\paragraph{Comments:} This is a goal. Ten-year lifetime for consumables does not apply here.
|
|
|
|
\paragraph{CAU Response:} OK, AHEPaM has no consumables.
|
|
|

|
\label{req:R-013}
|
|
The \acs{AHEPaM} shall be compatible with a storage duration of 2\,years.
|
|
|
|
\paragraph{Justification:} To provide schedule robustness against delays.
|
|
|
|
\paragraph{Verification:} Design/Analysis
|
|
