Yes, but what engine were they flying in F9R and Grasshopper? Both of those were lighted up for the entire flight and didn't bounce around.

The final approach is at 250 m/s. If I have this right, they'd be going about that fast if they started falling from zero velocity at 3 KM, ignoring air resistance. So, whatever parachute you use has to get you much lower and slower than that, and so precisely positioned above the barge that you can do the rest on the rocket.

Now, ULA plans to revive the Rogalo Wing from Gemini and combine it with the mid-air retreival from Corona, so this might not be completely absurd.

Sorry.

I guess then you were not so lucky as to have rocket scientists in the family. I guess I'm not unlike many techies my age, whose dads worked in aerospace. My dad worked on the lunar module at Grumman. My father in law worked in the blue cube for Lockheed.

People think of me an the Open Source guy. But I have been getting space spoon-fed to me since before first grade.

It's still slowing down during the last rocket length. That is really cutting it close, yes. I think the goal is to use an absolutely minimal fuel expenditure. The current configuration is not capable of landing after a GTO insertion. When they were considering doing the test for the DISCOVR flight, they were not going to have enough fuel for the normal recovery sequence, and were planning to delete the subsonic decel burn and come up to the barge at 1 KPS rather than the leisurely 250 m/s.

Armstrong did punch out of an LM trainer before that mission. It crashed and burned. They say that afterward, he went back to his office and quietly did some paperwork.

Well, it did what SpaceX was paid for reliably, which was to send the Cargo Dragon up to ISS in an expendable rocket. All of the NASA demo and supply flights they have done have been successful.

Recovery is so far a secondary and private mission of SpaceX, and Musk did say it had less than a 50% probability of success for this attempt (but a 75% to 80% probability of success for the year).

Me, I'm damned impressed that they can bring that thing from 78 miles high and suborbital speed, and touch the landing gear down on the barge at an acceptable descent rate. I think this is pretty good for the second try and they'll nail it soon enough.

Just look for one that says "Fallout Shelter"

If you think that's bad, read some of the comments to nontechnical news site articles on the recovery failure. Ignoramuses whining "how much of my taxes did this failure use". They aren't even smart enough to realize that it launched the Dragon to ISS successfully, and that NASA isn't footing the bill for recovery attempts. It's really enough to kill one's sympathy for the common man.

Step 1) Call/email ahead and say you are totally harmless.
Step 2) Fly/Drive/Swim vehicle packed to the gill with explosives right into your target without bother.
Step 3) Prophet!

I was surprised by something in the re-entry profile. They use what they call "lift" from tilting the rocket body against the air stream to control horizontal motion. I call it "falling with style". So they can go back uprange some distance without an additional fuel expenditure.

All of their communication so far has been that they can get back to the pad with the F9 or the two outer stages of the F9 Heavy. The center stage of F9 Heavy would probably need the barge.

So instead of there being a helicopter in the air with a human at controls

What about an auto-gyro with 30 lbs or so of C4? Do you still want the "human at the controls"? You don't know what the intentions are, you just know it's very illegal to be there yet there he is.

At this point you'd have to be an idiot to be a terrorist and not try to pilot a small explosive laden gyro into some major target, since it's obviously so easy.

I can't believe the "no fly zone" over Washington is such a total sham with not even a monitoring aircraft on top of him. Just like the Pirate Code, the No Fly Zone appears to be more of what you would call guidelines than an actual rule...

It's gotta come from the right clearance to get there.

Come on, he had AT LEAST 100 feet of clearance. If that's not enough I don't know what is.

That would be hot for an aircraft, but it was the planned vertical speed profile for the rocket. The grid fins need speed to work and they are the main control surfaces. The cold gas thrusters don't have infinite gas behind them and the engine burns are very short.

Advertisers value people, period. Even those with very little money... it's a different demographic, is all. The thing is people using free internet connections are not going to have that much money period so it simply does not match with your thought the advertisers on such a service will be expecting rich people on a limited free service.

Anyone who prefers to view the internet as a wealth-enabling resource

I do, which is why I'd prefer as many people to have internet access as possible - not hold it back from the poor in some ideologically misguied desire to "protect" them.

They planned the fast approach. Consider that the main control surfaces are the grid fins. They don't work at slow speeds. It's all about landing with the minimum use of weight (thus fuel).
