SpaceX - The Quest For Mars


If you mean store it,…in all the empty oil wells…everyone knows that…


I’ll definitely be glued to that one also.


Adds a whole new meaning to “sequestering your data”. :smiley:


Ah, in this?


More private Rocketry this time from NZ

World’s first orbital-class rocket launch from a private launch site


What is this, A ROCKET FOR ANTS !!!


Some footage of last week’s Falcon 9 heavy booster static test fire. … test-fire/


If either of these ever reaches potential, Musk will probably not be a happy camper. … mbergdaily


Its years behind SpaceX, Blue Origin are the ones to watch but even they don’t reach orbit until 2020


It’s a rocket for people who can’t sum good and want to do other things good too

Beautiful 4K footage of the last 1st Stage recovery

Well, that’s just nonsense! More of the Tesla is a Ponzi scheme bull.

SpaceX are demonstrably disrupting the space launch business.


Where’s the fraud, who is the victim, NASA ? people buying cheap launches ?

SpaceX is a private company that makes a profit most years, nobody is being scammed, in fact anyone launching with SpaceX has saved millions, in NASA’s case its billions and for the US military it will also be billions


I tend to agree, I’m not anti SpaceX. I think they do offer cost benefits over Orbital ATK, NASA etc. who have become inefficient bloated bureaucracies. Just an interesting alternative viewpoint.

At least the blog is appropriately titled: Playing Devil’s Advocate…


The guy doesn’t know what he is talking about.

1 The business case of a company does not depend on achieving regular engineering breakthroughs or refusing to use government money/research. Apple did not invent the GUI or smartphone, and most developments in major aerospace companies were based on military funding and research. (In any case, if he’s not impressed by vertical powered landing of orbital-class stages and developing engines with unmatched thrust-to-weight ratios, then he won’t be impressed by Red Dragon or cislunar flight. Much of SpaceX’s achievements are due to incremental improvements and the willingness to take risks by applying newer, more cost-effective techniques than their risk averse competitors.)

And SpaceX is already the cheapest launch provider, even without reuse.

2 Most rockets currently used by Russia were originally developed as ICBMs, so reuse was never a high priority. Developing rockets/rocket engines is incredibly expensive, especially if you have short production runs. This is why the former USSR has extended the production run of old designs whose development costs were paid long ago by the military. Few organisations have attempted to design an engine for reliability, long life, reusability, and redundancy. You can determine engine reliability by testing, and you could argue that new engines might be less reliable than used ones (bathtub curve) .
However, it is possible that reuse could affect reliability. It is also possible that reuse cannot be achieved economically (as was the case for the Space Shuttle.) There is an interesting question about the economics of reuse versus mass production (reuse reduces the advantages of mass production and hence the ability to offset development costs). Success is not guaranteed, but I would not bet against SpaceX achieving its goal.

3 Some people have mortgages that are only 20 percent of their gross income, that doesn’t mean it’s unimportant. And while launch costs are less significant for a one-off, high cost spacecraft like the James Webb Telescope, they make a big difference to systems that use a large number of identical satellites, like Iridium.

4 and 5 He does not understand the commercial launch sector. The US lost virtually all of this market to Europe in the 1980s due to the high cost of the Space Shuttle (and later ULA rockets) compared to Ariane; the Russians grabbed some of this market after the fall of communism; now SpaceX appears set to dominate. Lobbying and high entry costs have protected ULA from competing with SpaceX on (non-COTS) government contracts, but SpaceX has begun to win USAF and NASA contracts.
In the near term, SpaceX will never get Russian or Chinese government launches, but the Russian space sector will shrink due to the loss of commercial contracts to SpaceX. If reuse is achieved, Russia, China and Europe will have to throw money at the sector to copy SpaceX or die. The real dangers to SpaceX are Blue Origin (Jeff Bezos has much deeper pockets and can withstand heavy losses for decades) and Elon’s more grandiose plans (the ITS is an incredibly risky proposition).

And as for not disrupting the space sector, ULA has had to slash its workforce, halve its launch prices, and announce that its next rocket would be partially reusable.


SpaceX has just won it’s third military contract, which will be completed before the earlier two. In August it will launch the Air Force’s super secret “mini shuttle” X-37B. No-one really knows what the X-37B does. Spying is considered the most likely purpose. Previous SpaceX government contracts were from NASA and others. … h-contract


Air Force/Taxpayers save $300M+ with every Space X launch as compared with ULA. Call that a repayment of subsidies… … ch-prices/


For anyone not with the familiarity of the X37b.
