The dramatic images of a space shuttle launch lighting up the Florida sky or of a spacewalking astronaut hundreds of miles away sometimes mask one of the true achievements of Americas space program: the economic development it has spawned here on Earth.
Our national ambition to explore space has brought us tremendous discovery and unparalleled moments of pride. It has also created an industry. The aerospace sector has created tens of thousands of well-paying high-tech jobs and generated thriving communities - all of which are under threat if our government doesnt act quickly.
The United States is rightly looking to the next phase of its space exploration agenda. For several years NASA and its industry partners have been working on new spacecraft to return humans to the moon and - when the mission calls - journey beyond to destinations such as Mars.
Even as currently envisioned the years-long gap between the first flight of this new initiative known as the Constellation Program and the last flight of the space shuttle next year could result in nearly 10000 layoffs by NASAs largest contracting firms. Delaying key decisions or making major changes to current development programs could only exacerbate this problem. My company Boeing and others could lose many of the engineers who through their unique experiences working on the space shuttle International Space Station and other programs are among the United States most important strategic assets.
President Obama understands the importance of American leadership in space science and technology. He recently pledged to exceed space-race levels of research and development funding. Other countries are now beginning to pull ahead in the pursuit of this generations great discoveries he said. I believe it is not in our character the American character to follow. Its in our character to lead.
The presidents commitment is encouraging. Boeing and companies like mine have been investing in exactly the kind of human capital development that will be needed to fulfill Mr. Obamas vision. But in this noble pursuit of a robust new generation of scientists and engineers lets not leave behind the ones we have.
NASA and its industry partners have been working for several years to transfer the capabilities of our people to the next generation. Together weve developed retention packages to ensure skilled engineers stay with the space shuttle through its last flight and we ve offered wide-ranging re-training programs. Weve alleviated job losses within the budgetary and policy guidelines weve been given. Still thousands of our talented teammates are facing pink slips.
Id like to see the administration and NASA not only recommit to development of components like the Ares V cargo launcher rocket and the Altair lunar lander but also speed up awarding of these contracts. Thousands of jobs could be saved if NASA were allowed to put its contractors to work sooner rather than later on these important components.
Americas space agency has a strong history of learning from past mistakes. After the Apollo program ended abruptly in the 1970s - with the first flight of the shuttle still years away - NASA experienced exactly the kind of brain drain I now fear. It took years maybe decades to recover. In the 70s there was little time to plan. This time not only do we have the benefit of hindsight - we have foresight. We know this personnel crunch is coming. We can do something about it.
