For those of you waiting to see a few more frames of the landing for a better idea of the final disposition.

Sooo close!

If you watch at 1080p, you can really see it struggling to right itself at the end. Poor thing :(

That is way cool! Thanks for calling attention to it. [STRIKE]It seems that it came in a bit off and over-corrected.Then it can't stop the oscillation.[/STRIKE] Actually, it is swinging like a pendulum when it enters the frame. I wonder how far up it was wobbling like that.

Seems to me that the software controlling the main engine is to blame -- it took a second or two too long to fix its first overcorrection.

Of course that's easy for me to say as an arm chair physicist. I'm curious to know how their responsive control software works.

It is really great to so them attempt this and almost succeed, but I can't stop wondering if it is not cheaper to use solid rocket boosters as the first stage that drop into the sea and get refitted.

In any case at least the supplies got to the ISS:

The SpaceX Dragon cargo spacecraft was berthed to the Harmony module of the International Space Stationon Friday at 9:29 a.m. EDT while the two spacecraft were traveling above the coast of Sierra Leone. The spacecraft is loaded with more than 4,300 pounds of supplies, science experiments, and technology demonstrations, including critical materials to support about 40 of more than 250 science and research investigations during the station’s Expeditions 43 and 44. The capsule is scheduled to spend five weeks attached to the station.[/QUOTE]
The next ISS supply shipment is about to burn up:

crash test dummies for space
 
I've reviewed the OP's intent and have find that unmanned missions need not be mannequined.
[QUOTE=Uncwilly;322773]For all of you space buffs and fans, it is time to vent!

What is the most overlooked mission that you think should happen now?
What is a mission that you think should be given priority?
What mission would fill in some vital piece of knowledge or provide a new window of insight or explore new territory?

The rules:[LIST][*]It must be an unmanned mission.[*]It must not be directly overlap any current or currently [U][COLOR="DarkRed"]planned[/COLOR][/U] mission. This includes ESA (and all other European space agencies), NASA, RSA, [URL="http://b612foundation.org/"]B612[/URL], JAXA, and all other national agencies.[*]You have ~$1billion to work with.[*]No breakthrough tech allowed.[*]Must launch within 7 years and flight time to destination must be under 10 years. Primary Mission time is open, but must be covered by the funding.[*]Launch vehicles must be near term available (no SLS, but Falcon Heavy is ok), max of 2 launches, and the cost of the launches are part of the $1B. (Assume that the launched craft can auto-dock if needed).[*]A nominal amount of Deep Space Network support is available for a token charge.[/LIST]
Surprise us. Be creative.[/QUOTE]

[QUOTE]The test of “Crew Dragon” spacecraft, scheduled for May 6, will help NASA abort from a launch or pad emergency and safely carry crew members out of harm’s way, the US space agency said in a statement.

The test will simulate an emergency abort from a test stand on Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida.

The Dragon capsule will also have a dummy astronaut named Buster.[/QUOTE]
