Worth the Price? Should We Even Need to Ask?

By Nicholas Snow | Published: 22 August 2011 
The Space Race in the 1960s was an epic battle for supremacy in space exploration between the United States and the Soviet Union. National pride and prestige seemed to be a driving force as the Cold War waged on. The Soviets were the first to send the worlds first artificial satellite, Sputnik 1, into orbit and the US were the first to successfully land a man on the moon. The real question, though, boils down to whether or not this was all worth it? Certainly there were gains, many of them we are still seeing come to fruition but its hard to imagine the counterfactuals of what we missed by spending the money the way the Soviet and US governments did.

In today’s document, Henry Hazlitt’s 1962 Business Tide Column article for Newsweek entitled “Worth the Price?”, the question of whether the Space Race was worth the price is addressed. It is particularly interesting to see Hazlitt’s perspective given it was written before we had reached the moon. Hazlitt ultimately sounds as if the price is far too high and the reason deals with the inability of the government to properly assess the costs and benefits of engaging in the space exploration.

For many, if space exploration was to occur at all, it needed to be conducted by the state. The costs are simply too great and the ability to transform the possible benefits, such as scientific and technological discoveries, were too difficult to transform into “profits” for private businesses to undertake. But with a new space race starting to develop this claim is becoming less true.

The new race seems to be between NASA and private companies attempting to reach Mars.

Back in 2007 NASA stated the goal of putting a man on Mars by 2037 and recently the private company SpaceX, which is already attempting commercial space travel, stated their goal of establishing a means of getting to and from Mars.

As technology is improving the discovery process of the market is in full swing with entrepreneurs finding new ways of improving and satisfying the desires of his fellow man. And space exploration seems to be in the cards.

The difference between NASA and the private companies is in the price. With NASA we need to ask, like Hazlitt did some 50 years ago, is it worth the price? But with the private company, no such question exists because the market, through the profit and loss mechanism, provides the answer. Going to Mars is a risk; it may or may not be worth the price. With NASA the government takes our money whether we like it or not and there are no signals to say whether it was truly what people want or not. With private companies, however, if the venture is not worth it, they would know because they would have lost money. Money, which was voluntarily provided at the investor’s own risk. If it pays off then the rewards will be in the form of profits and others will follow suit, further reducing the costs and increasing the availability for others.

Asking whether something, particularly expensive as space exploration, is worth the price is an important question. And it is a question we should have a real answer for. So, maybe this, as with so many things, is another example of the state overstepping its bounds.

SpaceX Dragon reaches orbit atop a Falcon with a fiery tail

By Matt Ford | Ars Technica
Until recently, there have been two classes of people playing with rockets: those of us who enjoy playing with small (and not so small) toy models in our backyards and open fields, and the governments, who get the big boy toys to do some serious rocketry. Recently, private companies have been getting into the act and showing what can be done.

A few years ago, Scaled Composites' SpaceShipOne completed the unprecedented act of putting a human into space (the edge of space, mind you) and returning him safely to Earth. Yesterday, the Space Exploration Technologies corporation one-upped them by becoming the first nongovernmental entity to put a vehicle into low Earth orbit.

 SpaceX's Dragon spacecraft has been designed to carry a crew of up to seven (or cargo) into a low Earth orbit, and return them to Earth safely. It has been developed as part of NASA's Commercial Orbital Transportation Services program and is ultimately designed to pick up where the Space Shuttle will leave off, ferrying people and cargo to and from the ISS.

Wednesday morning, an unmanned and unladen Dragon spaceship was perched atop a two stage Falcon 9 rocket set to head off to orbit. Lift off from Cape Canaveral occurred at 10:43am; at T +10:00 the Dragon capsule successfully separated from the Falcon 9 launch vehicle and entered a near circular orbit at an altitude ranging from 288km to 301km (178-187mi) above the planet.

While in orbit, engineers put the Dragon craft through a battery of tests and maneuvers to explore its capabilities. After just over three hours and two orbits of Earth, a deceleration burn was carried out, which sent Dragon plummeting back to Terra firma. The heat shield, critical to any space craft surviving re-entry, held and the craft safely splashed down in the Pacific Ocean at 2:02pm, landing about 500 miles west of Baja California.

This represents a milestone in the private space industry, but only a single step in a series for the Dragon program at SpaceX.  Two more launches are scheduled over the next 18 months, hopefully culminating in approval from NASA to dock with the ISS. From there, manned flights become a real possibility. Then the doors may swing wide open on the private space travel industry.

Video of the launch can be viewed through NASA's website.
