| SpaceX's Falcon 9-R development vehicle appears to have flown again, according to this blog post. No details will likely be available until SpaceX talks about it.
Update: Video released by Elon. This flight went to an altitude of 1000 meters and lasted over two minutes!
According to SpaceX, early flights will have the legs start deployed, as shown here, but will later start with them stowed, and deploy shortly before landing.

| Wow! Never saw rocket flying in backward direction and landing))

| Quote Destructor1701 (  ) SpaceX are seeking EPA and FAA clearance to begin testing a reusable propulsive-landing dragon capsule. It'll be conducting grasshopper-style test flights at McGregor.
That's good news. There's already a propulsion system on Soyuz landing capsule, so if you just amplify them by factor of 50, it will be a good landing system. Although some safety questions rise.

Not really, the Soyuz landing propulsion is a solid rocket, which is not useful for controlled propulsive landings. So you need a fundamentally different type of propulsion system, one which is easily controllable and deeply throttleable, and which preferably uses the same onboard propellants as existing thrusters. So the obvious answer is hypergolic-fueled engines, which is what they're using. They've actually been testing that exact engine, the SuperDraco, for a few years now. They have been talking about propulsive landings for Dragon for a long time.

| HarbingerDawn, ok, then, probably they're talking about this type of system:
http://news.bbc.co.uk/2/hi/science/nature/8024590.stm
There was the time when Korolyov suggested using rocket engines for landing and a new perspective space ship, which should have used only rocked engines. It is about that time he said: "How long we're going to fly on the rags?", meaning that parachutes should be replaced with something more controllable. Unfortunately, after his death, not much was done in regards to Zarya project.

Yes, exactly. They have already shown concept videos of how they plan to implement this, the first one was in 2011, and the following vid from 2012 is the most recent:

| Are they not using parachutes at all?

It will have parachutes, but I think their plan is to not use them except in emergencies. At least eventually. But during some of the tests, they will be using parachutes and rockets together.

| SpaceX just released a new video of SuperDraco thruster testing, no doubt to build hype in the days leading up to the Dragon v2 unveil. Deep and rapid throttling is evident.

| And did anyone see the new SuperDraco engine test? Man, that was some fast throttling!
I'm back, but am I here to stay? Hopefully!

| Spyro, that post belongs here (and as you can also see here, the video of that test has been posted already).

| Just watched; that was really fantastic. Sleek, almost minimalist design, room for 7, and propulsive landing with redundant engines + chutes. "This is how 21st century spacecraft should land."
