'Everybody has won, and all must have prizes'

In space circles, the idea of offering incentive prizes to develop complex technology has some currency.  Most notably, Republican presidential candidate Newt Gingrich recently advocated a prize-based incentive model coupled with a leaner NASA as an alternative to our currently stalled, government bureaucratic model of space operations.  The incentive idea is behind the current Centennial Challenges program of NASA, which offers money for the demonstration of certain specified technologies or procedures.  Presumably, Gingrich is speaking not of this existing program but about a vastly expanded prize structure, funded by the federal government, for significant milestones in humanity’s expansion into space.

This model structure harkens to early days of aviation when prizes for specific aeronautical achievement proliferated.  Notable was the $25,000 Orteig Prize offered by New York hotelier Raymond Orteig for the first non-stop air flight between New York and Paris.  Charles Lindbergh won the Orteig Prize in 1927 in his specially built Spirit of St. Louis.  After this flight, probably due more to celebrity culture and the frenzy of fame rather than actual flight accomplishment, commercial aviation enjoyed a boom of popularity with the public and industry.  In short, the prize offering succeeded in producing a PR stunt; the design features of Spirit of St. Louis were specifically optimized to permit Lindbergh to win the prize, not to advance aeronautical technology or establish commercial transatlantic flight operations.

Currently, the most visible prize structure for spaceflight is Peter Diamandis’ X-Prize Foundation, a private funding group that awards prizes for specific space-related goals.  The first and most famous, the Ansari X-Prize founded in 1996, was offered to the first non-government group that could (within two weeks) twice launch and safely return to Earth a reusable, manned spacecraft.  In 2004, the $10,000,000 X-Prize was won by Burt Rutan’s SpaceShipOne, funded by Microsoft’s Paul Allen.  This vehicle used an innovative airborne launch system, a hybrid solid-liquid rocket engine and a “wing feathering” method for re-entry and return flight.  Plans were immediately made to construct a commercial version of SpaceShipOne, to be sponsored and operated by Richard Branson’s Virgin Galactic organization.

However, since that prize-winning flight almost eight years ago, things have not proceeded smoothly.  An explosion in 2007 destroyed the rocket fabrication facility and killed three workers.  Virgin Galactic established an operations base in New Mexico on October 17, 2011.  There is a passenger manifest backlog of 455 subscribers but as of this writing, not a single commercial passenger spaceflight has occurred.

Another current space prize is the Google Lunar X-Prize, offering a $20 million award for successfully landing a spacecraft carrying a high-definition imaging system and roving on the Moon at least 500 meters.  Since its announcement in 2007, over 30 companies have registered to participate in the competition.  Additional prize increments are awarded for other accomplishment, such as long range (> 5 km) roving, survival over a lunar night, and documentation of the presence of water in lunar soil.  No lunar mission has yet been launched nor has any launch date been announced.  The original expiration date for the lunar X-Prize was 2012 but was extended to the end of 2015.

An alternative incentive approach is milestone-based contracting.  NASA’s Commercial Orbital Transportation Services (COTS) program awards government money to companies that meet specific milestones on previously announced timescales.  That money is to be spent developing specific capabilities required for government needs.  The reward at the end of this cycle is a performance-based government contract for launch services.  However, under this government-sponsored incentive program, a commercial human spaceflight industry has yet to develop.

Bigelow Aerospace, a builder of private, “For Lease” space stations, recently laid off over one third of their workforce.  Part of the problem is the lack of assured, commercially available access to their orbital stations.  In 2004, Bigelow himself established and funded a $50 million prize to develop a commercial crew vehicle for orbital transport; the prize expired in 2010 without a single attempt at flight.  Although rumor has it that Boeing is developing a spacecraft to serve private space stations, nothing has yet appeared, even in prototype form.  Due to some unidentified technical issues, SpaceX has delayed the launch of the first flight of their Dragon cargo vehicle to ISS from early next month to an unspecified future date.

The simple glaring fact is the United States has no commercial human spaceflight industry.  NASA’s attempt to encourage the development of such through COTS is floundering against some unpleasant realities:  it is both very difficult and very costly to get into and back from space.  The former drives up the cost, severely limiting potential markets.  The latter stops not only imagined demand (such as space tourism) dead in its tracks but also real demand, such as government contracts for ISS crew access.

The hope of space prize enthusiasts for explosive growth in space similar to that seen in aviation innovation and industry following the winning of the Orteig Prize is unlikely to be realized.  The problem is that spaceflight is a vastly more difficult field in which to participate than aviation.  Many amateurs could and did fabricate aircraft in their garages and barns in the early decades of the last century.  The First World War made surplus aircraft widely available at low cost, furthering the development of a robust early aviation industry.  In contrast, no one has flown a surplus government space vehicle and “barnstorming” rockets do not exist, despite some imaginative depictions in Hollywood films.

Unfortunately, this is the space program we now have.  No American human spaceflight flight systems exist and their development is dependent on the advent of a demand that has not yet materialized.  Meanwhile, we comfort ourselves with fantasies about human missions to Mars.  I appreciate and applaud Gingrich’s enthusiasm for space, a visionary attitude sorely lacking in most politicians.  He needs to think carefully about how to incentivize the development of space and about the critical national needs served by our civil space program.  Prizes seem attractive because of their historical role in stimulating a nascent aviation industry.  But significant differences between aviation and spaceflight and our primitive level of development of the latter suggest that what worked before may not work now.

SpaceX Falcon 9-Dragon to replace Shuttle Cargo after 2010 - NASA announces

Hawthorne – NASA today announced its selection of the SpaceX Falcon 9 launch vehicle and Dragon spacecraft for the International Space Station (ISS) Cargo Resupply Services (CRS) contract award. The contract is for a guaranteed minimum of 20,000 kg to be carried to the International Space Station. The firm contracted value is $1.6 billion and NASA may elect to order additional missions for a cumulative total contract value of up to $3.1 billion.

"The SpaceX team is honored to have been selected by NASA as the winner of the Cargo Resupply Services contract," said Elon Musk, CEO and CTO, SpaceX. "This is a tremendous responsibility, given the swiftly approaching retirement of the Space Shuttle and the significant future needs of the Space Station. This also demonstrates the success of the NASA COTS program, which has opened a new era for NASA in US Commercial spaceflight."

Under the CRS contract, SpaceX will deliver pressurized and unpressurized cargo to the ISS, and return cargo back to Earth. Cargo may include both NASA and NASA-sponsored payloads requiring a pressurized or unpressurized environment. SpaceX will provide the necessary services, test hardware and software, and mission-specific elements to integrate cargo with the Dragon delivery capsule.

In 2006, SpaceX was named a winner under NASA's Commercial Orbital Transportation Services (COTS) competition. Under the existing COTS agreement, SpaceX will conduct the first flight of its Falcon 9 launch vehicle and Dragon spacecraft in 2009. The final flight, currently scheduled for 2010, will demonstrate Dragon's ability to berth with the ISS.

Falcon 9 flight hardware has already started to arrive at the SpaceX launch site, Space Launch Complex 40 (SLC-40) at Cape Canaveral, in preparation for Falcon 9 going vertical on the pad within a few weeks. Construction of the SLC-40 launch site is proceeding ahead of schedule and is estimated to be completed in early 2009.

About SpaceX

SpaceX is revolutionizing access to space by developing a family of launch vehicles and spacecraft intended to increase the reliability and reduce the cost of both manned and unmanned space transportation, ultimately by a factor of ten. With its Falcon line of launch vehicles, powered by internally-developed Merlin engines, SpaceX offers light, medium and heavy lift capabilities to deliver spacecraft into any altitude and inclination, from low-Earth to geosynchronous orbit to planetary missions. On September 28, 2008, Falcon 1, designed and manufactured from the ground up by SpaceX, became the first privately developed liquid fuel rocket to orbit the Earth.

As a winner of the NASA Commercial Orbital Transportation Services competition (COTS), SpaceX is in a position to help fill the gap in American spaceflight to the International Space Station (ISS) when the Space Shuttle retires in 2010. Under the existing Agreement, SpaceX will conduct three flights of its Falcon 9 launch vehicle and Dragon spacecraft for NASA, culminating in Dragon berthing with the ISS. SpaceX is the only COTS contender with the capability to return cargo and crew to Earth. NASA also has an option to demonstrate crew services to the ISS using the Falcon 9 / Dragon system.

Founded in 2002, the SpaceX team now numbers more than 620, located primarily in Hawthorne, California, with additional locations, including SpaceX's Texas Test Facility in McGregor near Waco; offices in Washington DC; and launch facilities at Cape Canaveral, Florida, and the Marshall Islands in the Central Pacific.
