There is a MISSE-FF overview in the CRS-13 thread if anyone isn't already familiar with it:

With Iridium slipping to Sat 3/31, let's preempt a few questions:
1. Odds of this effecting CRS-14 = Almost no chance
2. Station will take priority for Visiting Vehicle schedule
3. 2 days btw 2 launches is totally doable.

Sorry to be pedantic, but:

Odds of this effecting (i.e. performing) CRS-14 = zero!
Odds of this affecting (i.e. having an effect on) CRS-14...

I know it’s an optical illusion but it sure looked like vehicles were awfully close to the pad during the static fire

M1382 CRS-14 Launch Hazard Areas visualization based on issued NOTMAR and NOTAMs.

Green launch hazard area A doesn't include LZ-1 this time.
Orange landing/splashdown area B is relatively far away compare to previous CRS missions.
Despite the FCC application referring to LZ-1 recovery, this is apparently expendable mission for block4 B1039.2.

If this is indeed expendable it will be the sixth mission in a row that expended a booster (5 of the 6 intentionally  :)) )

Even though SpaceX expends their boosters for a reason, I'm getting sick and tired of them doing "expendable" missions rather than landing the boosters.

I feel that same.  Isn't that amazing?

Yeah, I was curious and looked it up: The vehicles are 4 miles (6.5 km) from the pad while the camera is located 10 miles (16 km) away  :)

It ain't amazing. It's more like redundant and annoying.

Think of it from SpaceX's standpoint...  cost of doing business for a day...
It's cheaper to give the soon to be outdated stages a Viking funeral... then it is to recover and chop them up...
Soon enough... they will be back to the "new normal" of recovering every one they can... no worries...  :)

I bet they'd recover them for you if you brought a big enough check...and a trailer. ;)

It seems that they are now going to recover tomorrows launch, which is nice.

I feel the same way, when they can recover on some missions, the boosters should be recovered instead of dropping somewhat randomly into the ocean.  It would be sweet to see them at all of their facilities entrances... 

These Boosters I feel are going to be pieces of History.

Are you sure? According to the other thread it's now an expendable launch. Huh. I don't know what is what now!

I should be precise, by "tomorrow" I meant Iridium 5 NEXT flight 5 : March 30, 2018

Iridium5 Falcon is vertical.


The picture shows the Grid fins and legs mounted.   Sorry the picture did not come over with the quote.

NRC Quest already reached northern part of appropriate hazard area "destination LZ 005" and is waiting in this "landing zone" for B1041.2 splashdown.
High Speed Fairing Boat Mr.Steven is heading to southern part of area.

Also reports of NRC Quest on station.

Right.  All of that is true, but the West Coast ASDS is not on station and won't be leaving the dock in Los Angeles.  So, no recovery of Iridium 5.  What they are doing is continuing their reentry/landing testing over the water and using a forward stationed NRC Quest to receive telemetry data (otherwise the landing would be over the horizon from ground stations) and observe.  Mr. Steven will be further downrange to attempt recovery of the fairing half.  This is the same thing they did on the previous Iridium launch that wasn't recovered but also had legs and grid fins on it. 

As this thread is about CRS-14, any further discussion or questions about the Iridium-5 launch should be done in the appropriate thread:

There is a MISSE-FF overview in the CRS-13 thread if anyone isn't already familiar with it:
https://forum.nasaspaceflight.com/index.php?topic=42775.msg1707908#msg1707908

Alas none of this gives a mass for MISSE-FF.  Total external cargo is 926 kg per the mission overgview.
ASIM is 314 kg per their website. PFCS is 111 kg although it presumably has a FRAM as well, usually about
45 kg I believe.  That would leave 456 kg from MISSE-FF which seems on the high side.

Here is another data point, may help if you have the final numbers from CRS-13

The original planned NASA SpX-13 unpressurized payload mass (as shown in the ISS planning doc gongora linked) including MISSE-FF: 1080 kg 

The actual flown mass of the unpressurized payload mass of SpX-13 (once MISSE-FF was dropped from the manifest):  645 kg

Which suggests that the mass was about 435 kg (not sure if an empty passive FRAM was left in the trunk when it was dropped, so that mass may need to be further adjusted).  But, they were planning to launch with a certain number of the sample carrier slots already filled (7 on SpX-13).  So, if you're interested in strictly the Flight Facility and not including any of the sample carriers and samples' mass, it will be less.  If you're just interested in the launching mass of the whole experiment in launch configuration then it's probably pretty good.  Though it may be minorly different from the launch configuration mass on SpX-14 because the number of filled slots during launch will likely be different.  The number of filled slots is determined by trunk packing geometry and separations to the other trunk cargo.

If I understand this correctly, the MISSE-FF will be launched with empty slots, and the first five MSC will be installed by SSRMS shortly after arrival. Maybe I didn´t read it correct.

Quote
The MISSE-FF launches on a SpaceX Dragon Vehicle to the ISS, in the trunk area.
The facility is removed from the Dragon trunk by the ISS robotic arm, and placed on ELC 2, Site 3 on the starboard truss.
Five MSCs accompany the facility to orbit, and are robotically attached to the MISSE-FF shortly after arrival.
The facility has 12 “slots” for the attachment of 12 MSCs when the facility is fully populated. However, typical operations only have 11 or fewer MSCs installed- leaving one “slot” as a temporary berthing position during operations to retrieve MSCs that have completed their duration on orbit. Those MSCs can be replaced with new ones that contain new experiments/samples.
At the end of an experiment’s time on orbit, the MSC is retrieved by the ISS robotic arm and placed on the MISSE Transfer Tray (MTT) to be moved inside ISS through the Japanese Experiment Module’s (JEM) airlock.
Approximately six months later, additional MSCs are flown to orbit and attached to the facility- beginning a rotation process and continue to be manifested approximately every six months thereafter.
