meaning apples, oranges, ect.
The stuff that doesn't come in a pre-packaged container, likely freeze dried or dehydrayed.
In an interview on NTV last week, Mike Fossum relayed a story about how the crew anticipates the smell of the newly arrived cargo vessel. As they open the equalization valve, a little bit of the cargo craft's air leaks out and they can smell the oranges 
Must beat the rotting smell of <you know what> when the MPLM eventually arrived back at KSC for opening, after diverting to Edwards,

That's certainly one advantage of having a vehicle normally burn up in the atmosphere.

Maybe only interests me, but upcoming reboosts using ATV-3; looks like less eccentric orbit at the end of the second burn:
IMPULSIVE TIG (GMT) M50 DVx(FPS) LVLH DVx(FPS) DVmag(FPS)
IMPULSIVE TIG (MET) M50 DVy(FPS) LVLH DVy(FPS) Invar Sph HA
DT M50 DVz(FPS) LVLH DVz(FPS) Invar Sph HP

Power issue related to ATV? (Missed today's ISS update hour. Edit -- was noted at the top of today's broadcast.) Seen via @NASA_Johnson tweet: http://mobile.twitter.com/nasa_johnson/status/185841586834374656Link to status here: http://www.nasa.gov/mission_pages/station/living/index.htmlExcerpt: Late Thursday, Russian atmosphere scrubbers were activated to ensure the removal of any contamination in the ATV-3 that may have occurred when the pressurized cargo compartment was opened for pre-launch packing adjustments in the European space port in Kourou, French Guiana. When the scrubbers were activated, ATV flight controllers in Toulouse, France, reported the failure of one of two redundant Russian Equipment Control System channels that provide station power to ATV-3. The backup power channel passed an initial test today, but it has not yet been connected to station power systems. If a Saturday morning test is successful, the backup power channel will be used for a planned reboost Saturday afternoon using ATV-3 thrusters. If the backup channel does not function properly, the reboost will be cancelled.

Wow, so this is serious enough for a contingency undocking?  ATV-3 seems to be having an unfair share of problems.

Any other recent news on the problem with routing electric power to the ATV?
This is source of my query...http://www.spaceflightnow.com/ariane/va205/status.html
As part of a changed scrubbing process they had extra equipment that had not been certified plugged in. Likely caused a trip. Tmorrow the alternate power string will be brought up and determine if there is a real problem or not. Very likely just caused a trip and no failure but folks are planning how to unload the dry cargo ASAP just in case.

Really appreciate that information, especially heading into the weekend.

Wow, shocking news, but thanks for that tidbit.

What kind of timeline would we be looking at in the event that this can't be resolved? A few days, a week, a couple of weeks?

per L2, as early as Monday, however, let's not go overboard here, let the folks work the problem and see what they come up with.

No mention from the Russians on possible undocking; it fact, seems as though they expect first test reboost will take place as planned based on my far-less-than-expert use of Google translate: http://www.federalspace.ru/main.php?id=2&nid=18880According to the ballistic Service Mission Control Center Engineering Research Institute engines will be included in 1:00 and 54 minutes Moscow Time (March 31 at 21:54 GMT) and have worked for 411 seconds. As a result, the ISS will receive an additional boost of 1 meter per second. The average height of its orbit will increase by 1.7 kilometers and will be 389.8 kilometers.
