Can the US Still Lead In Space Despite Shuttle's End?
Hugh Pickens writes "NASA Administrator Charles F. Bolden says that the future is bright and promises that one day humans will land on Mars. 'American leadership in space will continue for at least the next half-century because we've laid the foundation for success,' the nation's space chief said in a speech at the National Press Club. 'When I hear people say that the final shuttle flight marks the end of U.S. human space flight, you all must be living on another planet. We are not ending human space flight. We are recommitting ourselves to it.' Bolden says within a year private companies can take over the process of sending cargo shipments into orbit and by 2015 industry can take over astronaut transport, freeing NASA to focus on the long-term goals of reaching beyond Earth's shadow. 'Do we want to keep repeating ourselves or do we want to look at the big horizon?' says Bolden. 'My generation touched the moon today, NASA, and the nation, wants to touch an asteroid, and eventually send a human to Mars.' A group of former astronauts and other critics have blasted the agency and the Obama administration for ending the 30-year-old shuttle program, once the cornerstone of NASA. 'NASA's human spaceflight program is in substantial disarray with no clear-cut mission in the offing. We will have no rockets to carry humans to low-Earth orbit and beyond for an indeterminate number of years,' write Neil Armstrong, Jim Lovell and Gene Cernan. 'After a half-century of remarkable progress, a coherent plan for maintaining America's leadership in space exploration is no longer apparent.'"
"Why does 'our nation' have to put a gun to my head and force me to fund the intellectual curiosity of others?"
You pay already more than the complete NASA budget just for the fuel to run the AC in the tents in Afghanistan.
Yep. SpaceX and Dragon are clearly the emerging future of American human spaceflight. This video is a pretty cool demonstration of how the system is evolving.
Armstrong, Lovell, and Cernan are -- knowingly or unknowingly -- lobbying for an old, failed model of government contracting, not for the continuation of the American space program.
The program continues -- it's just being done in a different (and from everything I can see, better) way.
The shuttle was not a shining example of the US doing well.
It was a shining example of how much pork you can pack into one project and have it stumble along and achieve a bare fraction of the aims at huge cost.
For example.
Do you know why the shuttle has large wings?
It's largely so that it can take off, launch a military satellite into a polar orbit, and land back in the continental united states, without overflying russian territory.
Needless to say, it's never actually needed to do this.
But the requirement to do so meant the need for SRBs, and the complex thermal protection system. This was so that the DOD would kick in some funding into the project early on.
A shuttle launch costs a really, really large slice of a billion dollars.
SpaceX's Falcon Heavy is currently selling twice the amount of payload to low earth orbit, for well under a quarter of the price.
Yes, it's not quite as nice, as you need a few percent of that to be able to push it around a bit to match orbits you can reach with the shuttle.
And you need a bit more payload sacrificed if you actually want anything of significant weight recovered.
But the shuttle has only done that task perhaps half a dozen times, for payloads where in many cases it was debatable as to the value of doing so.
The shuttle has basically been the shining light akin to the caver that finds his way by periodically lighting his hair on fire.
SpaceX has already sent an unmanned Dragon capsule into orbit around the Earth. They have a contract with NASA for cargo flights to the ISS, and are developing the manned version of the Dragon with an integrated abort system (see this video for a demonstration).
American spaceflight is NOT coming to an end. It's just not going to be a NASA monopoly any more.
we have more probes on mars then any other nation.
And look at mars rover that lasted for YEARS longer then planned.
"Besides, what does NASA do for me anyway?"
Wow, I know they say there are no stupid questions but there sure seem to be a lot of inquisitive idiots.
You want to know what NASA and the space race has done for you....Look down at your keyboard, its attached to a computer.
Microprocessors were derived from the space race. As well as the satellite communications that you may use to connect with other idiots.
Not enough for you...heres some more things that were by-products of the space race and the space age.
Kidney dialysis machines
Computer-Aided Tomography (CAT) scan
Magnetic Resonance Imaging (MRI)
Freeze-dried food
Cordless power tools & appliances
Disposable diapers
Rotary blood pump
Fiber optics
Satellite dish
Bar codes
Ear thermometer
Fire-resistant fabrics
Smoke detector
Thermal gloves and boots
New techniques for machining and casting exotic metals like magnesium and titanium.
Carbon fiber epoxy, and all kinds of composite materials
CNC machining.
Microwave communications.
Huge improvements in photovoltaics (solar cells to generate electricty).
Solid state memory
Satellite photography
velcro.
And about 1,400 documented NASA inventions that have benefited U.S. industry.
Oh yeah did I mention TANG!!!!
I called you an idiot several times above. I may be wrong. You may just be an ungrateful, unimaginative Luddite. But I'm betting your both an an ungrateful, unimaginative Luddite and an idiot.
If you dont like it, you can always turn off your computer since NASA and the space race never did anything for you any damn way.
i could care less if the US is seen as the "leader" in space exploration.
Why do you hate America?
Faster! Faster! Faster would be better!
Oh for Pete's sake. Obama did NOT cancel the Shuttle program, George W Bush did! Obama canceled Constellation, the rocket program to followup on the Shuttle, but he did so because it was overbudget and behind schedule. I have a long-ish article about this in the New York Post today. NASA has some serious problems right now, mostly due to lack of a strong vision and the ridiculous turf wars between the White House and Congress. Most of these problems aren't hard to solve in theory, but in practice, with the rabid partisonship going on right now? Hmph.

This list seems at best dubious in many aspects.
MRI, for example, was an outgrowth of magnetic resonance studies on chemicals that had been going on for a long time, which was invented in england in the university of Nottingham.
I'd like to know how NASA influenced velcro - which was patented in 1948 in switzerland.
Thermal gloves and boots - what? I think you'll find the Eskimo (inuit) got there first.
The incas did freeze drying naturally hundreds of years ago, and freeze dried coffee was available around WWII.
Disposable diapers have a long history, and were around well before the 60s.
Kidney dialysis was done in WWII.
These are just some examples that jumped out at me as unlikely.
