SpaceX

SpaceX landed a first stage of a rocket on a drone ship at sea. Pretty impressive. The video is here. Skip to 27:00 if that's all you want to see.

I was at an engineering career fair for recruiting in January, and the line to talk to Space X was ridiculous. Pretty awesome stuff they are doing.

I was wondering the same thing. Anybody know of the core first stage was successfully recovered on the drone barge out at sea?

I can't believe there is a Tesla Roadster in space.

No.

Still quite the achievement, though.

the test payload doesnt have any boosters attached. Floating in Mars orbit around the sun. unless it smashes into mars or a large astroid hits it; it should stay in space for a billion years.

an automotive blog asked a few scientist if the car would still work if brought back to Earth..
if brought back to Earth right now; it would still work upon replacement of hoses and other things that might freeze in space.
interesting to note; if it had a solar panel; it could work on mars, being electric.. and not needing oxygen like a internal combustion engine.

if brought back to Earth in hundreds of years; they suspect tiny micro astroids would hit it and the two metals would bond via freeze welding

now articles are saying it wont even last a year; because of the astroid belt it has to go through plus radiaton.

stupid SpaceX marketing and making me believe it will last a billion years. I dont want to come back alive any more .

What was the verdict on the return of the core rocket to the barge in the ocean?

justn, you’re telling me the payload is IN Mars’ orbit right now. When did the launch happen?

..
The test mission of SpaceX’s Falcon Heavy, the most powerful operational rocket on earth, was supposedly intended to put Elon Musk’s Tesla Roadster in an orbit around Mars.

It was a little, let us say, heavy on the accelerator pedal: After a fly-by of Mars, the car will instead head beyond, to the asteroid belt.

The company had never really planned to put the car in an orbit directly around the planet Mars the way the moon orbits earth, despite Musk’s claim that its “destination is Mars orbit.” That would require in-space maneuvering which the Tesla Roadster is not equipped to do.

Instead, SpaceX intended to put the roadster into an orbit around the sun that would frequently bring it near to Mars, a preliminary step toward a direct approach. As you can see in the diagram above, the red car will pass by the red planet fairly closely, at least in terms of previous relative distances between cars and astronomical bodies.

But according to Musk—SpaceX hasn’t made an official statement yet—the vehicle “exceeded Mars orbit”; apparently there was more oomph in the second stage of the Falcon Heavy than expected, and now the Roadster will also get a fly-by of the asteroid belt. Astronomers and amateur space object trackers are trying to get more details from the company about the precise position of the unusual spacecraft.

It’s not bad news to learn that the vehicle is more capable than expected, especially after a six hour cruise through the radiation in the Van Allen Belt, which will help convince clients like the US Air Force to use the rocket in the future.

Tesla and “Starman,” its space-suited mannequin pilot, are off to scout the solar system. The question is, how fast will humans follow?

Are you telling me that a tesla roadster cannot maneuver in space?

I find that totally unacceptable!

The asteroid belt is very big. There are very large gaps in it, so big NASA doesn't really even bother to take it into account when travelling through it. I don't think anything humans have launched has crashed into an asteroid when passing through.

But there is also a lot of volume within the asteroid belt. The belt can be said to occupy a region around the Sun from about 2.2 to 3.2 times the distance from the Earth to the Sun from the Sun (AU), with a thickness of about 1 AU. A bit of math puts that at about 50 trillion trillion cubic kilometers. So even though there are trillions of asteroids, each asteroid has billions of cubic kilometers of space on average. The asteroid belt is hardly something you would consider crowded. It should be emphasized that asteroids in the belt are not evenly distributed. They are clustered into families and groups. But even such clustering is not significant compared to the vast space it occupies.

You can even do a very rough calculation to get an idea of just how empty the asteroid belt actually is. If we assumed that all the asteroids lay within a single plane, then on average there is 1 asteroid within an area roughly the size of Rhode Island. Within the entire United States there would be about 2000 asteroids, most of them only a meter across. The odds of seeing an asteroid along a cross-country road trip, much less hitting one, would be astoundingly small. So you can see why we don’t worry about space probes hitting an asteroid on their way to the outer solar system. In fact, to get even close to an asteroid takes a great deal of effort.

I'm confused. Did the car pass Mars already or are they referring to projected destination?

I wonder which sci-fi movie will use a similar model of the car to claim the hero is using it in Mars to save the day. "It's already got all the juice we need, baby!"

The car is nowhere near Mars, the plan had been to set it on an elliptical "Mars orbit"; unfortunately the orbit point was missed and the car is now set to end up in the asteroid belt near the orbit of Ceres, the largest object in the asteroid belt.

Yes. The rocket was launched yesterday. It hasn’t even broken the perimeter of the moon’s orbit yet. It is quite certainly not in Mars’ orbit and won’t be anywhere near Mars for another six months.

Also, “Mars’ orbit” is misleading. The target was an orbit of the sun around the region where Mars resides. Estimates are that it will go beyond that now.

My daughter's RIT roommate works at Tesla SpaceX plant in LA as a mechanical engineering intern.
She said the party they threw at the main Tesla plant was pretty amazing.

I know I guy who's a bartender down in that area. He said

"Bro work was insanity
Made 700 bucks so that was cool. But 13 hours was rough
Those guys went through like 35 kegs
We got an emergency delivery of 9 kegs, they were all gone in an hour"
