真實的故事在美國NASA復活的空天飛機背後

真實的故事在美國NASA復活的空天飛機背後
The Real Story Behind NASA’s Resurrected Space Plane

The aviation and space press buzzed last week with the news that NASA had quietly moved its two long-grounded X-34 space planes from open storage at the space agency’s Dryden center — located on Edwards Air Force Base in California — to a test pilot school in the Mojave Desert. At the desert facility, the mid-’90s-vintage, robotic X-34s would be inspected to determine if they were capable of flying again. It seemed that NASA was eying a dramatic return to the business of fast, cheap space access using a reusable, airplane-style vehicle — something the Air Force has enthusiastically embraced with its mysterious X-37B spacecraft.
航空和航天新聞上週唧唧響,有消息美國宇航局已悄悄地,從露天存放在航天局德萊頓中心 - 位於加州愛德華茲空軍基地 -移走它的兩架長期停泊的X - 34空天飛機,作 一次在莫哈韋沙漠的飛行員學校試飛。在沙漠的設施,90年代舊、機器人式的X - 34將被檢查,以決定它們是否能夠再次飛行。它看來美國航天局在把目光投向一個戲劇性的折返,對快速、廉價的空間訪問業務,以使用可重複使用、飛機式的交通工具 - 一些空軍已熱情地擁抱的東西,以它的神秘X - 37B航天器。
The truth, it turns out, is a bit more complicated, even confusing — but no less exciting. If everything works out, the X-34s might help pioneer not just an emerging method of accessing space, but a new space-exploration business model, as well.
真相原來是更為複雜的,甚至是混亂的 - 但沒有減少興奮刺激。如果一切順利,X - 34可以幫忙作先鋒,不僅是一個新興的方法進入空間,而亦更是一個新的太空探索商業模式。
A Wednesday call to Orbital Sciences, the original manufacturers of the X-34, resulted in a brief conversation with a bemused company official. Barry Berneski, Orbital’s communications director, said he had read the X-34 news, but had heard nothing on the subject from inside the firm. “They might be just trying get it out of Edwards’ valuable real estate,” Berneski said of the 59-foot-long space planes, only one of which ever flew — and just once — before the program was canceled on cost grounds in 2001.


In fact, real estate has been a factor in the X-34s’ moves over the years, Dryden official Alan Brown said on Wednesday. After the program’s termination, NASA transferred the space plane prototypes to the Air Force, “which thought it might use them but never did,” Brown said. “When the Air Force needed room in the hangar, they [the X-34s] were moved to a bombing range and sat out there deteriorating for several years.” The two bots luckily avoided getting bombed, and earlier this year NASA moved them back to its side of Edwards. “They were sitting there a while,” Brown mused.

The idea to ship the X-34s to Mojave and inspect them originated with a Dryden-based NASA engineer, Brown said. “When he found out this thing still existed … he decided people should take a look to see if it could be refurbished and made flightworthy.” That’s when the contractors came to retrieve the two neglected spacecraft, pictured above en route to the Mojave.

But that doesn’t mean NASA has formal plans to operate the X-34s under its own auspices, now or ever, Brown stressed. Provided they’re in flyable shape, it’s far more likely the space agency will make the X-34s available to private industry. “There are a number of firms interested in these things, developing communications and other technologies,” Brown said. “It would be helpful if they had a vehicle.”

Brown implied he was trying to downplay the X-34s’ possible resurrection, but his reference to private industry hints at a far more exciting future for the space planes than would be likely in NASA service. After all, America’s space future is looking increasingly privatized. In 2004, Scaled Composites boosted its Space Ship One vehicle to higher than 300,000 feet, proving that cheap, reusable, commercial vehicle could reach near-orbit — and potentially score huge profits from spacefaring tourists. And just this week, the Federal Aviation Administration issued the very first license for a commercial spacecraft to re-enter the atmosphere from orbit. The license will allow SpaceX to test, in December, an unmanned rocket vehicle designed for resupplying the International Space Station.

President Barack Obama’s space policies entail “outsourc[ing] major components of the space program to private industry.” With flyable X-34s at the ready, NASA could lend a hand to companies hoping to expand on Scaled’s and SpaceX’s achievements, and further open up space to explorers … and entrepreneurs. That’s way cooler than just another government-only test program, if you ask us.
