I want you to act as an Spacecraft Engineer. I will provide an extract of an Engineering System in triple format as well as a requirement, and it will be your job to analyze if the requirement is satisfied by the engineering system or not. 
First try to extract the information (entities and relations) from the System that is potentially useful in your analysis. 
Next try to establish if that information either implicitly or explicitly fulfills the requirement. 
This could involve performing a gap analysis between the engineering system and the requirement. 
The Final step is to clearly state if the requirement is satisfied or not by stating FINAL ANSWER: YES or FINAL ANSWER: NO.
My engineering system and requirement are: 

 System:|Spacecraft| |has_durationInstrument_Operations_Mode| "48180 h". 
 |Spacecraft| |has_durationSafe_Mode| "48 h". 
 |Spacecraft| |has_fractional_state_durationCommissioning_Phase| "undefined -". 
 |Spacecraft| |has_durationStand-by_Mode| "48 h". 
 |Spacecraft| |has_durationSun_Acquisition_Mode| "3.6 h". 
 |Spacecraft| |has_fractional_state_durationSafe| "0 -". 
 |Spacecraft| |has_fractional_state_durationSwitch_Instrument| "undefined -". 
 |Spacecraft| |has_fractional_state_durationManoeuvre| "0.05 -". 
 |Spacecraft| |dvhas_margin| "100 %". 
 |Spacecraft| |has_wet_mass| "1083.2 kg". 
 |Spacecraft| |has_dry_mass| "943.87 kg". 
  
Requirement: Goal Requirement: The spacecraft shall have a mass < 1000kg. 
Let's analyze the given System and requirement step-by-step: Your answer should have exactly 4 paragraphs. Make sure that the first paragraph starts with the word "open" and that each paragraph is separated by two new lines.
