Am I right in saying that it;s default path down is always to land in the water, It then makes the decision closer to the ground as to whether it can safely land or not and then corrects to go to the LZ?

Yessir. Default landing point is, indeed, offshore, and then changes to either the droneship or LZ-1 as programmed on-the-fly. There are abort points built in at key milestones of the descent in case of something going wrong so that it can change direction; at which case it'll attempt to land anyway but at a safe distance from anything & anyone so that Engineers can do a post-mortem to find out what happened and why.

 

It's a fantastic way to do things. Even though the rocket is doomed (and knows it), it'll still try to protect everyone and everything from bad stuff.

 

A classmate of mine who has since gone on to work for SpaceX has said they internally call it "Oh $#!% mode". :laugh:

The move from offshore to onshore is called a divert, and according to SpaceX"s Hans Koenigsmann Falcon 9 also knows not just where the pad is but where the surrounding structures are so that it can attempt to avoid them in case of a late failure.

For me it is a split between the first and second images.

 

The first because I am just a mountain/snow type of person, absolutely stunning photo. But then comes the second image, Dragon flying of a remote desert, no interference of mankind in sight (other than Dragon itself of course) 😛 If you were to show this image to they layman and told him/her that it is Dragon flying over the planet Mars am convinced they would straight up believe you and that is what makes it so frigging awesome!

 

Yeah I think i am going to roll with photo #2 :)

AIUI - no signals from shore to depressurize the tanks - it's part of the automatic  post-landing safing sequence.

 

Much of the roll reduction was likely due to the legs deploying.  Think of a spinning figure skater; arms in = spin fast, arms out = spin slow/stop. If nothing else it made it easier for the reaction control system and gambling Merlin to stabilize the vehicle.

    • RollerCoaster Tycoon 3 and Voidwrought are free on the Epic Games Store

      By LoneWolfSL · Posted

      RollerCoaster Tycoon 3 and Voidwrought are free on the Epic Games Store by Pulasthi Ariyasinghe PC gamers can now jump in and grab two more games to keep this week, as the Epic Games Store's ever-present giveaway promotion has just gone through another refresh. Replacing last week's Citizen Sleeper and Robobeat offers, the store has brought in RollerCoaster Tycoon 3 Complete Edition and Voidwrought to keep. From the duo, Roller Coaster Tycoon 3: Complete Edition is an enhanced version of the classic title that was originally released in 2004. It comes with enhancements such as widescreen and 1080p resolution support, as well as increased compatibility with modern PC hardware. It also comes bundled with all the extra content from the Soaked! and Wild! expansion packs. "Control park finances, shops, services and staff to succeed in dozens of scenarios," reads the description. "Become a true tycoon and embark on your promising new career, or create your ideal park without money woes in sandbox mode. Satisfy your guests’ needs and keep your park running smoothly to succeed." If management is not your style, Voidwrought lands as a 2D action-platformer featuring hand-drawn cosmic horrors. The title touts tight platforming and close‑quarters combat, all brought together with a strong emphasis on mobility. "Descend below the star-scorched surface and explore the multidimensional depths below," says the studio Powersnake about the game. "Witness the corrupted revelry of the Court, lose yourself in the icy tunnels of the Old Waters, and discover the grim fate of the Abandoned Expedition." The RollerCoaster Tycoon 3 Complete Edition and Voidwrought giveaways are set to run until June 25 on the Epic Games Store, giving PC gamers seven days to claim the latest offer. Once this closes out, new freebies will take their place on the same day as always. Don't forget that mobile gamers can check out the Epic Game Store's weekly giveaways on Android and iOS to grab a freebie there as well.
