This is probably the radio reflexive paint Elon tweeted about:https://twitter.com/elonmusk/status/871228411494014976I was under the impression that SpaceX used a simpler approach to landing, by just running the GPS LZ-1 coords through the navigation unit. In the case of DPL campaigns, the same happened with the stage AND the barge (barge ordered to keep its station, S1 calculated a 0-0 touchdown on the given coords before launch). Now they are using active radar?Nothing changed vs what has been speculated all along. GPS for navigation in general, radar altimeter used for low altitude readings, where its more accurate and lower latency to obtain readings (and it measures altitude to ASDS including waves instead of to sea level + normal ASDS elevation).Radar for civil navigation is always active. Passive radar is (pretty much) a military only thing when vehicles use enemy's radar emissions to find/target them.Radar altimeter was already used. Just LZ improvements to make its job more precise.

After its work was done on Saturday, for example, the Falcon 9 second stage apparently splashed down softly in the ocean southwest of Australia, Hans Koenigsmann, SpaceX's vice president of build and flight reliability, said during Saturday's press conference.
I noticed this:QuoteAfter its work was done on Saturday, for example, the Falcon 9 second stage apparently splashed down softly in the ocean southwest of Australia, Hans Koenigsmann, SpaceX's vice president of build and flight reliability, said during Saturday's press conference.in this article.Anyone know if that's true, or rubbish? I spotted at least one other factual error in the article, so the latter wouldn't surprise me.

He said nothing about it splashing down softly, which is most likely complete rubbish. You can find links to the press conference in the CRS-11 threads.

I missed the presser due to hosting an (unrelated) party, but figured NSF crowd would be all over it already if Hans had actually said that.
The NROL-76 reentry burn was called out as 25 seconds long. This one was significantly shorter. Are they continuing to optimize fuel usage, or is that due to different trajectories?
How close to the ISS will Dragon be tonight at 10pm pst? With Cygnus departing and Dragon arriving tonight's ISS pass might be really special.Sent from my SM-G903W using Tapatalk
On Sunday night, with Cygnus moving away from ISS and Dragon moving towards it, we will have the rare opportunity to spot three objects in the sky, chasing each other.I expect that Dragon will be approaching from behind, and by Sunday night (US ET) should be very close. Does anyone know which direction Cygnus will be departing in, and how fast the SS John Glenn will move away from ISS?If there another NSF thread where this is being discussed, please point me to it
Anyone catch the unberthing date in July from yesterday launch commentary? Was it 3 July?
You summoned a video! Dragon passing over UK - and the second stage & solar panel covers photobombing along the way. Not my video, but best one I've seen.QuoteDragon Resupply Mission (CRS-11) passing over Oxfordshire 22 minutes after launch from NASA’s Kennedy Space Center Florida. The two light in the middle are the Dragon capsule and the second stage, the two lights on either side are the discarded protective fairings tumbling away from the craft. Look for a thruster correction burst at 1min 12sec.

Just seen tonight's pass with an amazing demo of orbital mechanics- Dragon a few minutes ahead of ISS but moving much more rapidly in its lower orbit.

The sound of science that rocks!Congrats SpaceX. Loved the t-shirt on display at Hawthorne: "0 prayers given". Great.
