back to article Elon Musk's 'Grasshopper' hover rocket scores another test success

SpaceX, the radical upstart startup rocket firm helmed by PayPal hecamillionaire and geek visionary Elon Musk, has announced a further successful trial of its hovering "Grasshopper" test vehicle. According to the company: On Thursday, March 7, 2013, SpaceX’s Grasshopper doubled its highest leap to date to rise 24 stories …

Sony Music pulled the video, here in Germany...

Not retro-futuristic enough

Do you think we can persuade Elon Musk to redesign it so as to more closely resemble Thunderbird 3?

20 Years Later

It only took 20 years after the Delta Clipper (DC-X) project to make this happen... again. (google it)

Strange comment

"At touchdown, the thrust to weight ratio of the vehicle was greater than one"

Of course it was, what a pointless thing to say! Or is that just a fancy way of saying that it didn't crash land?

Re: Strange comment

No - a plane with the engines off still lands, rather than crashes, even with a thrust to weight ratio of 0.

This was actively hovering - not just a slowed descent.

Score: Elon 1, the other guys 5

Elon isn't too happy that he lost his lawsuit against Top Gear for showing his no so good EV dying on track. In addition Musk didn't do himself any favors with his public spat with the NY Times reporter who was candid about his 300 mile journey in a Tesla toy. Musk will also lose that lawsuit that hasn't been filed yet.

hearts a flutter

All of the Mars One fans are ooo'ing and ahhh'ing over this. This is a nice step forward in not having a "impact landing" on mars. Any landing you can walk away from and all that...

Well done you. It only looks simple when experts spend decades of man years making it come together.

always enjoy reading about SpaceX these days.

I am not a rocket or SpaceX fanboi, but they certainly seem to be pushing in a very interesting direction.

Interesting? Well, yeah but 'cheap' is a better word for what SpaceX is doing...

Interesting? Yes but much more significantly, SpaceX is doing more to get humanity off this planet than anyone else.

They're already cheaper than anyone else *cough*ULA*cough* in the business and is anyone else trying to make their rockets cheaper? Not that anyone can see.

SpaceX is also trying to make their rockets reusable (at the cost of reduced payload but that's not necessarily a bad thing for the Falcon 9 v1.1 & certainly not for the upcoming Falcon Heavy) which will reduce launch costs even more, and allow even more launches per year.

Make it cheap enough, and everyone'll do it...

>Make it cheap enough, and everyone'll do it...

One question is how elastic is the space market?

Apart from dreams of asteroid mining or exploration how many satelite launches does the world need?

Telecoms satelites haven't been competitive with fibre for nearly 2 decades, we have 4 separate sat-nav systems and geostationary is pretty much full - and becoming irrelevant in the Netflix era.

Re: Interesting? Well, yeah but 'cheap' is a better word for what SpaceX is doing...

How elastic was the exploration market just prior to Columbus? Spain wasn't desperately short of food or space and yet Columbus got his funding (but not the right to a percentage of all the returns from the New World, something that was denied to him in the small print - a lesson for all of us there...) to go off and explore.

There wasn't much of a return for Spain in the very early days but the New World became a galvanizing idea for the Spanish population (in fact, over the next two centuries Spain DEpopulated, its population actually shrank as people flooded out to the Americas) and they, followed by other Europeans, rushed out to develop and make a new life for themselves in the New World.

Make getting off the planet cheap and people will, again, be stirred up. People will, over time, head out to develop the New Frontier and, in time, make a new economy, of ideas, of trade etc.

I like the spanish blocke tied to the side of the rocket, check out the video near the end. Big Cajones!

Great work, similar to the LEM but better with automatic control

The Lunar Excursion Module did a similar landing during the Apollo Moon missions. The first Lunar landing was a problem because the surface of the original landing site was full of boulders about the size of cars and the crew had to go to manual control and change direction to somewhere flatter.

The problem then was that the main engine was not at all designed for vectoring, they had to use the attitude jets (little cross shaped things all over the LEM) for directional control and modulate the main engine to allow a gentle descent or ascent. Thank god they had the sense to use a (somewhat) modulating engine or they would a different kind of history.

Landing the LEM in full manual with an untested engine was truly a scary feat of flying.

This Grasshopper is just like those old SF movie landings with a full rocket landing vertical (Destination Moon). Let's see them do it in a 25 mph breeze now. That will be the real test of the automated control system.

"Merlin rocket engine"

I remember when Merlin engines drove propellors...

Also, when did VTOL become VTVL?
