Question about landing a traditional rocket


In the preview trailer they show Musk Space X trying to land a traditional rocket and of course it crashes. What's that all about, why would you ever think you could land a tall, skinny rocket? Even the shuttle was basically an oversized jet that landed on wheels like a jet. Isn't Musk wasting his time? Then there is Musk and others taking about the difficulty of landing a ship on the surface and indeed in the series the landing almost fails. Is this dramatic license? If you can't figure out how to land on Mars, man you are a long way from getting there too. At this rate of innovation we are 100 years from landing on mars.

Of course it won't be a rocket landing on Mars. Either a shuttle will come down from a large ship in orbit, like we did when landing on the moon, or the ship itself will fly in and land like a jet or a Harrier jump jet, like in Prometheus, the film. Why don't they have this concept in this series? Can it really be because they wanted the landing to be difficult for dramatic reasons? if so, that's bogus.

I was wondering the same thing. Good series, though.

If two people think the same thing, it must be true. Well, at least it's not just me.

Wings don't work on Mars.

reply

I think the point was not necessarily wings, but the concept of four (or more) thrusters on a wider, more stable, craft.

reply

I guess you haven't been following SpaceX AT ALL. They have made quite a few successful booster returns, with both barge landings as well as at Cape Canaveral.

The Falcon 9 Flight 20 first stage is now on display outside the SpaceX facility in Hawthorne CA.

Why are they even trying to return and land tall skinny rockets, it makes no sense, of course there will be failures.

reply

From what little I can understand, Elon wants to be able to have reusable rockets. He's wants to cut the costs in space exploration, which is one of the things holding it back. By cutting the costs with reusable rockets, they'll be able to make Mars runs more often I think.

reply

As BlackiesDad said they have succeeded in landing "tall skinny rockets".

People shouldn't post comments until they research them.

reply

So... just saying... if they've done it successfully, why was the only example they showed in the episode a failed landing? (Not questioning that it's been done, but it was a stupid production choice given that not everyone follows the exploits of SpaceX.)

reply

The reason why the only example they had of a tall, skinny rocket landing attempt gone wrong was to show the hard work and research that goes into perfecting technology.

I am tired of the Elon Musk haters, it is total B.S. Innovators like Elon are the ones that will get us and guide us through the next century.

reply

Because they filmed it in the past. I saw the premiere of this in China a few weeks before on Nat Geo in the US. No idea when it was made, but I suspect for some other foreign market 6 months ago, and they never updated it with a successful barge landing.

"Either a shuttle will come down from a large ship in orbit, like we did when landing on the moon, ..."

Shuttle? It was a three-leg tin-can with a rocket!

reply

Four legs actually.

I think it has something to do with science, physics, launching a heavy object into air and having it arrive at a long distance target, similar to the principles of shooting an arrow, as described here: https://arxiv.org/ftp/arxiv/papers/1511/1511.02250.pdf

"What's that all about, why would you ever think you could land a tall, skinny rocket?": Because it turns out this is the best way to get a used rocket back. You could add wings but they add a lot of dead weight. It's simpler to just run your main engine backwards and add some landing legs. This is nothing new either, Science Fiction has rocket landing backwards since the 1950s, it's just in recent years we have the computer and avionics to make it actually happen.

"Isn't Musk wasting his time?": Hardly, seeing SpaceX already succeeded in landing his rocket. BTW it's not just Musk doing this, Jeff Bezos' Blue Origin is also landing rockets, this is the way of the future.

"Then there is Musk and others taking about the difficulty of landing a ship on the surface and indeed in the series the landing almost fails. Is this dramatic license?": No, landing on Mars is super difficult (see recent ESA Mars lander failure for example) and it is a major obstacle for manned mission to Mars.

"Either a shuttle will come down from a large ship in orbit, like we did when landing on the moon, or the ship itself will fly in and land like a jet or a Harrier jump jet, like in Prometheus, the film. Why don't they have this concept in this series?": Because this is the concept currently being studied by SpaceX. There's some good reasons they want to do it this way, both technical and economical, a bit too long to explain here.

I think there was a lack of imagination so far, because they jumped years ahead and
apparently they are continuing to do things the same way. Big (and bigger) rockets traveling from Earth to Mars.
Four years is a good time to get an orbiting station going, and managing arrival and
departure operations at Mars. (Or at least they should be building it already.)
Also, I have wondered why the original crew stays in Mars. They should have returned to Earth after one or two years. Did I miss something? Was the mission one way?

reply

From what I've seen and read, I believe the mission was one way. According to makemarshome.com, they predict 100 people will inhabit MARS by the year 2050, so it seems that everyone who goes to MARS during this time plans to spend the remainder of their lives there.
