Quote from: Demidrol on 04/03/2018 09:07 amI have not heard any calls about the re-entry burn start/complete in the webcast. Has there been re-entry burn?I’m not sure. Maybe this new landing profile involved reentering the atmosphere WITHOUT conducting an entry burn, and using a 3-engine landing burn at the last second.

I seem to recall hearing on the webcast in the flight audio loop a call out saying that Stage 1 AFTS had been safed. That was considerably after the time frame where the first stage would have "landed". Could this be some proof that Stage 1 survived its landing regime and splashdown and SpaceX has to deal with another floater?

I'm surprised that nobody has mentioned the apparent debris that was visible on the video after solar array deploy.The first object flew past quickly from left to right at T+15:03 to 15:05.The second one moved much more slowly and tumbled. It was visible from T+15:10 to 15:24 when it disappeared in front of the solar panel. It seemed to me to have lodged in the wiring harness.

Almost all of the questions from the press and social media sites were for SpaceX. So, no it's not boring. SpaceX is where the action is.According to Chris G, there were only 10 members of the press at the prelaunch conference. I am not saying your claim isn't valid, but the evidence supporting it is not the greatest.

In the post launch press conference Jessica Jensen said they didn't do a landing test, there was no soft landing in the ocean.

Has there been re-entry burn?I’m not sure. Maybe this new landing profile involved reentering the atmosphere WITHOUT conducting an entry burn, and using a 3-engine landing burn at the last second.As far as I can recall, there has never been a case where the stage was destroyed during entry, or survived but was damaged enough it could not restart/land. So SpaceX has not yet found the shortest entry burn that could be used. This would have been (and maybe still is) a great set of experiments for the old block 3/4 boosters they are not trying to re-use. Try shorter and shorter entry burns, and for each one make sure the landing burn still works, the grid fins were not destroyed, and so on. They would not want to try this with a block 5, since finding the edge of the envelope means losing a booster.
The 5 additional sample carriers mentioned in that NASA explanation are being transported in the pressurized section of the Dragon, in CTBs. They will be transferred out through the JEM A/L and robotically installed on the Flight Facility after that is on the ELC.

An optimal landing is also one that preserves the longevity of the vehicle.

I noticed in the ISS Daily Summary Report that they used "Forced Based Capture, a software enhancement to the Latching End Effector (LEE)" to catch the dragon but I could not find further information about this. Does anyone know more about this new procedure?
During a survey of LEE A on February 28th, one of the snare cables was found to be damaged. CSA analysis predicts load limit exceedances for certain SpaceX-14 capture scenarios. Ground teams are coordinating to determine the forward path for SpacX-14 capture operations.
The crew then reconfigured the JEM ORU Transfer Interface (JOTI) and installed the MISSE-FF Transfer Tray (MTT) on the slide table and loaded it with 4 MISSE Sample Carriers.
