A1Q1

Today’s your chance to ask us, the OSIRIS-REx team, your #asteroid sample return mission
questions using #askNASA!

@OSIRISREx #asteroid BennuSampleReturn #askNASA Why does #MAVEN #OSIRISREx &
#JupiterExoliner have the same bus but different Solar Panels?

.@TierraUniversu #Maven is at Mars, which is further from the sun than OSIRIS-REx at
#Bennu, it needs larger solar panels for req’d power.

@LockheedMartin #asteroid #askNASA What are the Lifespan of @MAVEN2Mars @OSIRISREx & the
#JupiterExoliner and how far can they go?

.@TierraUniversu For OSIRIS-REx, our design lifetime is 7 years. We will travel over 6
billion km roundtrip.

@TierraUniversu @OSIRISREx: #MAVEN has enough fuel to orbit #Mars for another 9 years,
depending on use as a comm. relay vs. science orbit.

Q5

Our spacecraft launches next September on a seven year mission to bring back a sample of
asteroid #Bennu. #askNASA

@OSIRISREx #asteroid #skNASA What would have been needed to speed up Mission to as low as 3
to 4 years?
