As Mr. Musk has tweeted, you wouldn't want to ride to Mars in a dragon capsule since the inside is about the size of an SUV. But, getting it to Mars and successfully landing it would be an accomplishment.

I would love to see an advanced propulsion systems that could cut the time of the trip down to say 4-6 weeks. Granted, that is not an easy task, but a quicker trip would makes things safer and easier: less food, water, air to carry, less exposure to solar radiation, easier to get somebody back quickly if needed, etc.

Once I met some of the old timers at materials science function. They used to tell me how they had to wait until 8 am until they could start work. They were so jazzed about their work that they would jump the fence and break in so that they could get an early start. I liked my engineering career fine but I was never that enthusiastic.

Glad to see someone stepping up and pushing forward. It's long past time we got out there again.
That's what we're talking about!

It also puts my own (and most peoples) meagre accomplishments firmly in perspective. But that's ok.

If just a handful of people (out of 7 billion) can do that, imagine the untapped potential we all have. Seems humanity (me included) suffers from a very deep lack of faith in our capabilities and commitment to achieve wonders.

It gives me a mix of hope, pride and sadness at the same time. Hope and pride Elon is doing this, sadness that he's an exception amidst the Ubers, Facebooks, Instagrams and investment banks (to name a few in my view) who claim to be changing the world, but aren't really in a positive meaningful way.

I was stuck in the Huntsville, AL area for work a couple weeks ago but found a few hours to visit the Nasa Space & Rocket Center there. A fair bit of it is oriented toward kids but I still enjoyed it a lot. There were Shuttle and various military exhibits, but my main interest was the old Apollo stuff. I ran into a staff volunteer who had been a Saturn propulsion engineer and he talked with me for over an hour.

When I was finally on the plane to go home (near Detroit) I pulled out the latest issue of Air & Space magazine to read and quickly hit an ad for Spacefest VII in Tuscon in June. I was not even aware that there was an astronauts' convention going on like this and when I got home DW and I made a quick decision to go. I think it will be a blast(off).

Of course, this one the first stage was coming in at twice the speed as the previous landing, which required four times as much energy to slow the descent, and eight times as much heat had to be dissipated.

Their webcast are getting increasingly educational and professional. Between playing Kerbal Space program and watching their webcast, I think I've learned and ten times as much about rocket science as I have in my previous 50 years of being a space geek.

And for those wondering, the naming comes from a science fiction writer Iain Banks.

"Just Testing" would have been nice too, or "What Are The Civilian Applications?"

I especially like "Read the Damn Manual".

Here's an interesting article on Musk, SpaceX and why Failure is an Option.

Quote:
With his rocket company Musk has dreamed big dreams. He has unflinchingly talked about landing humans on Mars in the 2020s, which is at least a decade before NASA and its international partners, and their plans which will cost hundreds of billions of dollars, might hope to do so. To boldly go to Mars requires risks. It requires accepting failure. And so when the most likely outcome on Friday morning was that his rocket would break apart in a fiery calamity for all the world to see, that was OK. SpaceX had failed before, and it would again. Exploring the frontier of physics, engineering, and aerospace isn’t for the timid.
Or as Q told Captain Picard:

Quote:
If you can't take a little bloody nose, maybe you oughtta go back home and crawl under your bed. It's not safe out here. It's wondrous, with treasures to satiate desires both subtle and gross; but it's not for the timid.

The CFO of SpaceX is a grad of our local university. He gave a talk last week. She went, and we took our 5th and 8th grade girls out of school for the talk.

They loved it!

I consoled myself with these cool NASA posters I had made a few months ago and put in our basement.

He also seems to have made embracing failure is ok part of the culture. The articulate webcasting crew, made it a point to emphasize that even if they failed to land the first stage "THAT WE WILL STILL LEARN A LOT"

One still has to remember where the line "Failure is not an option" came from. According to this site Gene Krantz never said it, but it was attributed to him in a movie, supposedly during the Apollo 13 mission. The stakes were a bit higher then...

Quote:
"As far as the expression 'Failure is not an option', you are correct that Kranz never used that term. In preparation for the movie, the script writers, Al Reinart and Bill Broyles, came down to Clear Lake to interview me on "What are the people in Mission Control really like?" One of their questions was "Weren't there times when everybody, or at least a few people, just panicked?" My answer was "No, when bad things happened, we just calmly laid out all the options, and failure was not one of them. We never panicked, and we never gave up on finding a solution." I immediately sensed that Bill Broyles wanted to leave and assumed that he was bored with the interview. Only months later did I learn that when they got in their car to leave, he started screaming, "That's it! That's the tag line for the whole movie, Failure is not an option. Now we just have to figure out who to have say it." Of course, they gave it to the Kranz character, and the rest is history."

Back in 1970 when I was a tad younger a manager red faced and swearing(they did that back then) threw me out of his office when I made the mistake of disparaging a Vanguard model on his desk as one of our less than stellar efforts to catch up with the Ruskies.

Try, improve, evolve is still prone to bad press once in a while.

heh heh heh - If the cost equation has shifted as much as hoped we have a barn burner in options to structure and plan future missions.

Wish I knew! I'd buy a ticket myself.

The poster, on the other hand, was found on Etsy.

Another successful launch and booster recovery for Space X today, though the booster landing did push the limits of the vehicle's landing system.

Quote:
Elon Musk ‏@elonmusk 2h2 hours ago Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion. Prob ok, but some risk of tipping.
