(What's with the dark blue mouse on the light blue background just below the Dragon trunk?)
Quote from: Comga on 07/28/2016 04:41 am(What's with the dark blue mouse on the light blue background just below the Dragon trunk?)It probably means that mice are being carried by SpX-10 to ISS for some experiments.
How many life biological cargoes (and I'm talking about macroscopic animals here, not the microorganisms in the cheese) has Dragon carried to date?
ExplanationPlease explain in the area below why an STA is necessary:This STA modifies information from previous application 0830-EX-ST-2016. This STA covers the experimental first-stage recovery operation, following a Falcon 9 launch from Cape Canaveral. This request is limited to the TC uplink from an onshore station at CCAFS. This includes pre-launch check-out operations at CCAFS as pre-coordinated with the launch Range. Launch vehicle flight communications for this mission are covered by a separate STA. The current launch planning date is NET 11/10/2016. The requested expiration date is 6 months following the grant date or upon completion of the experimental recovery operation, whichever occurs first.
According to next FCC application issued at 09/23/2016 there is CRS-10 flight from LC-40 still NET 11/10/2016 with landing targeted to LZ-1.https://apps.fcc.gov/oetcf/els/reports/STA_Print.cfm?mode=current&application_seq=73865QuoteExplanationPlease explain in the area below why an STA is necessary:This STA modifies information from previous application 0830-EX-ST-2016.

A launch from 39-A could still land the booster at LZ-1, couldn't it? Does it matter if the launch is one place and RF another?

I don't believe grid fins would be able compensate if the booster missed LZ1 by that distance.
There have been calculations in prior mission threads, or perhaps the General Falcon & Dragon thread, that body lift and the grid fins' ability to modulate angle of attack basically give the F9 stage maybe 15 - 20 miles of cross-range from the end of the boost back burn to landing. Can't remember which thread(s) this has been discussed in but a search might locate the posts.
