There will be quite a bit of aerobraking during the science mission itself, though. That's the whole point of the unique solar panel shape, so as to fly through the atmosphere lower than any other orbiter has gotten.


Not really.

MAVEN will go lower than other orbiters have in routine science ops - but not as low as other missions have during aerobraking passes. MRO was routinely doing passes of 97-105km during aerobraking ( http://issfd.org/ISSFD_2007/3-3.pdf ) - Odyssey went as low as 95km.

The MAVEN deep deep campaigns only go as low as 125km. The impact on its apoapsis will be pretty negligible..

MRO and MGS oriented their solar arrays to have aerodynamic stability during their aerobraking, Odyssey parked it's solar arrays 'behind' the spacecraft bus to have a similar stability. MAVEN doesn't articulate its arrays - so the inherent stability had to be designed in - hence the solar panel configuration.

Thanks Doug; that explains it well.
So Odyssey is the record holder unless we exclude MCO, (and I don't think anyone wants to count it today of all days wink.gif)

Everything looks good so far on MAVEN.

We had a great track on the 70 metre dish in Canberra today.
Ops team said that it went so smoothly that we could have almost done it completely automated except for the manual switch from LGA to HGA.

Great job by the team here and in Goldstone. Handing over to Madrid team later tonight (our time) after the 4 second test burn for MOM.

Congratulations to MAVEN! Now that it's a Mars orbiter I've created a subforum for it in the Mars Orbiters forum, and started a new thread for the mission's commissioning phase.
