太空總署:2020年月球建前哨站 通火星跳板
法新社╱紀錦玲 2007-12-11 14:05
(法新社華盛頓十日電)美國官員今天表示,雖然經費還沒著落,不過,美國國家航空暨太空總署正朝著重返月球的目標邁進,預定二零二零年前人類再登月球,並且在月球上設置前哨站,作為通往火星的跳板。
太空總署一年前曾經宣布具有遠大企圖的計畫,將在月球南極上建立太陽能發電、有人駐守的前哨站。一年後的今天,太空總署官員吉布瑞契在華府告訴記者說,「我們的工作是:要在月球上建立城鎮,最終在火星上留下太空船的輪胎痕跡。」
太空總署「星座計畫」主管韓利表示,「我們已經有國際太空站了,也將建立月球前哨站,當然,總有一天,人類會登上火星。」星座計畫主要負責發展人類登陸月球的交通工具。
目前任職太空總署探險系統任務理事會的太空飛行老兵華茲表示,「三十五年前的這一週,太空人塞南、艾萬斯與施密特正站在月球上。我們目前正努力工作,希望將未來一代的太空人再度送上月球」。
吉布瑞契表示,雖然預算限制,但太空總署希望星座任務能夠在二零一六年以前全面運作。
他說,「我們希望國會能夠通過預算。」他指出,支持總署的太空計畫,花費納稅人的錢並不多,在每一美元的納稅錢中,只有零點六美分是花在太空計畫上。
「這項預算案能夠實現總統的願景─在二零二零年,人類再登月球。」
人類登陸月球任務已睽違數十年久,布希總統於二零零四年宣布重返月球新計畫。
韓利表示,「我們將分階段執行重返月球計畫。」
他說,第一階段有關於建構完成國際太空站後,太空梭將在二零一零年除役。
「接下來重點是,建造新的太空梭,也即新星座計畫的獵戶號與阿瑞士號。」
韓利指出,「我們已經有了基礎開始,很快地,就可以有大系統興建工程,包括建造阿瑞士V型火箭、月球登陸船,以及在月球地表興建工作站系統。」他再度強調,太空總署目前正面臨預算的困境。

NASA on target for return to the moon by 2020: officials
Mon Dec 10, 7:26 PM ET
WASHINGTON (AFP) - Despite funding uncertainty, NASA is on track to return humans to the moon by 2020 and set up a lunar outpost to serve as a springboard to explore Mars, officials said Monday.
"Our job is to build towns on the moon and eventually put tire prints on Mars," NASA's Rick Gilbrech told reporters here, one year after the US space agency unveiled an ambitious plan to site a solar-powered, manned outpost on the south pole of the moon.
"We have the International Space Station; we're going to have a lunar outpost, and someday, certainly, somebody will go to Mars," said Jeff Hanley, head of NASA's Constellation program, which is developing the tools to return humans to the moon.
"Thirty-five years ago this week, Gene Cernan, Ron Evans and Jack Schmitt were on the surface of the moon. We are working hard to return a future generation of astronauts to the moon," said space flight veteran Carl Walz, who now works for NASA's exploration systems mission directorate.
Despite budgetary constraints, NASA hoped to have Constellation fully operational by 2016, Gilbrech said.
"We're hoping we get a budget passed by Congress," he said, pointing out that only six-tenths of a penny of every tax dollar went to funding NASA's space programs.
"We're making plans to be ready for any and all scenarios. The (budget proposal) we put in keeps our program on track for the March 2015 initial operating capability... and full operating capability a year later," Gilbrech, who leads new spacecraft development at NASA, said.
"That will enable the human-moon return by the 2020 date that the president envisioned."
President George W. Bush in 2004 announced a plan to resume human flights to the moon after a decades-long gap.
"We're doing this effort to get back to the moon in phases," said Hanley.
He recalled that the first phase involved retiring NASA's space shuttle in 2010 after completing construction of the International Space Station.
Following that, attention will be focused on building the shuttle's successor, the Orion crew vehicle and Ares launcher of the new Constellation program, he said.
"Very soon, and we have already begun at a low level, we will ramp up rapidly to build the big systems which are the Ares V rocket and the lunar lander and the surface systems that will be put in place on the moon," Hanley said, again stressing budgetary constraints faced by NASA.
"We will begin that build-up after 2010 because that's how our budget is put together. We're going as we can pay, so to speak. This is a long-range strategy we're rolling out over the next two decades and more," he said.
"It will be a challenge, a challenge to do it on budgets the Apollo missions didn't have to deal with, and to get people interested and keep them interested," he said.
"In May 1961, then US president John F. Kennedy proposal to send astronauts to the moon before the end of the decade launched the Apollo era."
The pioneering program achieved its goal eight years later, on July 20, 1969, when Apollo 11 commander Neil Armstrong became the first man to set foot on the moon.
The December 1972 flight of Apollo 17, with Cernan, Evans and Schmitt on board, was the last manned mission to the moon for the United States.
