QUOTE (craigmcg @ Nov 19 2013, 12:53 AM)  And now we wait... Not really ... they will communicate (nice DSN visualisation ) And other activities will also happen: - Two to three weeks after launch, most of MAVEN’s instruments will power up for the first time and perform a post-launch checkout. - The 6 instruments in MAVEN's Particles and Fields (P&F) Package will remain powered on and will collect data during the cruise to Mars. - During the MAVEN cruise phase, flight operators will execute at least four trajectory correction maneuvers (TCMs). |

Also they plan to observe comet ISON, if ISON survives it's trip around the back of the Sun.

Two instruments have been turned on and checked out: NGIMS and IUVS.

in case anyone is interested, I recently asked to the MAVEN twitter account whether they went ahead with the planned observations of comet ISON or not and this was the answer:
QUOTE UVS took 12,000 images in 10 modes (12/11-12/13), originally slated for ISON observation, but useful for diagnostic data obtained

So MAVEN has already done a couple of Trajectory Correction Maneuvers without any problems. The last, TCM-2, was on February 27. TCM-3 is currently scheduled for September. The MAVEN team is also keeping busy with instrument tests; cruise is only 10 months, so apparently it's actually a pretty busy time.
Anyway, question: at what point would MAVEN get its own subforum under "Orbiters"? After it has successfully achieved Mars orbit and started its nominal mission? Doug M. |

It had a successful trajectory correction on June 11, and is due to make another this coming Sunday 14 Sept. The plan is for Mars orbit insertion on September 24, two days after Maven.

Once ub orbit, then orbital position will need adjusting over a month or so. I'm sure soon enough we'll start getting some data in after that objective is complete.

What factors lead the team to opt for a series of engine burns to lower the 35 hour capture orbit to the 4.5 hour science orbit instead of the now "standard" aerobraking?
 I've tried searching the forum and Google for an answer and can't find one. |

If you don't need to use aerobraking....why bother. It takes time, has its own risks, and incurs operational costs. It was an enabling technique for MGS, MODY and MRO. MAVEN can get to the orbit it needs to without aerobraking. It's not like carrying extra propellant cost them anything, they used the lightest launch vehicle available.

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.

Also... it's a mistake to think of something as standard if the people involved have never done it before. One reason for other nations to fly these kinds of missions (lunar orbiters, landers, Mars orbiters) is to develop those skills themselves. Until they have done it, it is anything but standard.
