Last space shuttle comes home, ends 30-year era

MARCIA DUNN, 07/21/11

CAPE CANAVERAL, Fla. (AP) — Atlantis and four astronauts returned from the International Space Station in triumph Thursday, bringing an end to NASA's 30-year shuttle journey with one last, rousing touchdown that drew cheers and tears.

A record crowd of 2,000 gathered near the landing strip, thousands more packed the space center and countless others watched history unfold from afar as NASA's longest-running spaceflight program came to a close.

"After serving the world for over 30 years, the space shuttle's earned its place in history. And it's come to a final stop," radioed commander Christopher Ferguson.

"Job well done, America," replied Mission Control.

The twilight landing, just before dawn, came 30 years and three months after the very first shuttle flight in 1981. It will be another three to five years at best before Americans are launched again from U.S. soil, with private companies gearing up to seize the Earth-to-orbit-and-back baton from NASA.

The long-term future for American space exploration is just as hazy, a huge concern for many at NASA and all those losing their jobs because of the shuttle's end. Asteroids and Mars are the destinations of choice, yet NASA has yet to settle on a rocket design to get astronauts there.

Thursday, though, belonged to Atlantis and its crew: Ferguson, co-pilot Douglas Hurley, Rex Walheim and Sandra Magnus, who completed a successful space station resupply mission.

Atlantis' main landing gears touched down at 5:57 a.m., with "wheels stop" less than a minute later.

"The space shuttle has changed the way we view the world and it's changed the way we view our universe," said Ferguson. "There's a lot of emotion today, but one thing's indisputable. America's not going to stop exploring.

"Thank you Columbia, Challenger, Discovery, Endeavour and our ship Atlantis. Thank you for protecting us and bringing this program to such a fitting end."

The astronauts' families and friends, as well as shuttle managers and NASA brass, gathered near the runway to welcome Atlantis home — and bid the shuttle program goodbye. Mission Control in Houston also was packed, teeming with past and present flight directors. Hundreds of other Johnson Space Center employees stood outside, watching the landing on a jumbo screen.

NASA's five space shuttles launched, saved and revitalized the Hubble Space Telescope; built the space station, the world's largest orbiting structure; and opened the final frontier to women, minorities, schoolteachers, even a prince. The first American to orbit the Earth, John Glenn, became the oldest person ever in space, thanks to the shuttle. He was 77 at the time; he turned 90 this week.

Born with Columbia, it was NASA's longest-running space exploration program.

It was truly a homecoming for Atlantis, which first soared in 1985. The next-to-youngest in NASA's fleet will remain at Kennedy Space Center as a museum display.

This grand finale came 50 years to the day that Gus Grissom became the second American in space, just a half-year ahead of Glenn.

Atlantis — the last of NASA's three surviving shuttles to retire — performed as admirably during descent as it did throughout the 13-day flight. A full year's worth of food and other supplies were dropped off at the space station, just in case the upcoming commercial deliveries get delayed. The international partners — Russia, Europe, Japan — will carry the load in the meantime.

It was the 135th mission for the space shuttle fleet, which altogether flew 542 million miles and circled Earth more than 21,150 times over the past three decades. The five shuttles carried 355 people from 16 countries and, altogether, spent 1,333 days in space — almost four years.

Two of the shuttles — Challenger and Columbia — were destroyed, one at launch, the other during the ride home. Fourteen lives were lost. Yet each time, the shuttle program persevered and came back to fly again.

The decision to cease shuttle flight was made seven years ago, barely a year after the Columbia tragedy. President Barack Obama nixed President George W. Bush's lunar goals, however, opting instead for astronaut expeditions to an asteroid and Mars.

Last-ditch appeals to keep shuttles flying by such NASA legends as Apollo 11's Neil Armstrong and Mission Control founder Christopher Kraft landed flat.

It comes down to money.

NASA is sacrificing the shuttles, according to the program manager, so it can get out of low-Earth orbit and get to points beyond. The first stop under Obama's plan is an asteroid by 2025; next comes Mars in the mid-2030s.

Private companies have been tapped to take over cargo hauls and astronaut rides to the space station, which is expected to carry on for at least another decade. The first commercial supply run is expected late this year, with Space Exploration Technologies Corp. launching its own rocket and spacecraft from Cape Canaveral.

None of these private spacecraft, however, will have the hauling capability of NASA's shuttles; their payload bays stretch 60 feet long and 15 feet across, and hoisted megaton observatories like Hubble. Much of the nearly 1 million pounds of space station was carried to orbit by space shuttles.

Astronaut trips by the commercial competitors will take years to achieve.

SpaceX maintains it can get people to the space station within three years of getting the all-clear from NASA. Station managers expect it to be more like five years. Some skeptics say it could be 10 years before Americans are launched again from U.S. soil.

An American flag that flew on the first shuttle flight and returned to orbit aboard Atlantis on July 8, is now at the space station. The first company to get astronauts there will claim the flag as a prize.

Until then, NASA astronauts will continue to hitch rides to the space station on Russian Soyuz spacecraft — for tens of millions of dollars per seat.

Ever since snagging this plum assignment last year, Ferguson and his crew have tried to stay upbeat — focusing on the 30 years of success. They pointed to the delivery and repair of Hubble — one of 180 satellites and other spacecraft launched from the shuttles — and the completion of the space station, more than 12 years and 37 shuttle flights in the making.

But with thousands of layoffs coming as early as Friday — on top of thousands of shuttle jobs already lost — even Atlantis' determinedly optimistic crew found it difficult at times to put on happy faces.

Local businesses and communities chimed in, hoping to ease the pain.

"Thank you shuttle workers," read the sign outside Cape Canaveral City Hall.

After months of decommissioning, Atlantis will be placed on public display at the Kennedy Space Center Visitors Complex. Discovery, the first to retire in March, will head to a Smithsonian hangar in Virginia. Endeavour, which returned from the space station on June 1, will go to the California Science Center in Los Angeles.

AP writers Mike Schneider at Cape Canaveral and Seth Borenstein in Houston contributed to this report.

連隱形戰鬥機 F-35 都難產.

跟英國的超級航空母艦一樣: 昨日黃花!

但是未必會為星際旅行計畫買單。這就是問題的關鍵--什麼狀況下需要把資源集中給超越個人的主體(國家)或公法人;什麼狀況下需要把資源分散到個體或私法人?

腦蟲不是討論什麼大政府小政府的問題。

在全世界200多個上下的國家中,混到老二,還非得有兩把刷子不可。我那有「預估」美國「倒台」?

美國的問題在長期舉債渡日,一旦全球崛起,其巧取豪奪、騙吃騙喝的聲勢和空間不再,自然不得不面臨算總帳的一天和隨之而來的下場。套句美國俗話:

The writing has been on the wall for a long long time.

中國不是沒有自己的問題。我的三個前提都不是可以靠吆喝、吹口哨、或喃喃自語達成。我也各提出可供佐證兩國走勢的指標性事件。因此,我的「預估」是「條件性」的educated guess

50年太空計劃和30年太空探測一旦難以為繼,做為「一葉」,綽綽有餘。老夫觀察和判斷一向有根據和邏輯,豈能以「天馬行空」視之?

美國太空任務暫停是國庫捉襟見肘的結果。以美國目前的經濟實力,2030年代中期登陸火星的「遠程目標」云云,不過是個下台階的說辭。

沒有銀子難辦事。美國過去50年的太空計劃帶動了廣泛和一系列的科技研究以及大大小小衛星工業的蓬勃發展。這次暫停或喊卡,自然對這些活動有重大的負面影響。從而,也會遲滯美國未來經濟力的建構。

中國只要能在10年內設法避免國內各民族間的大型衝突以及社會各群體的大規模抗爭,同時維持穩定和一定幅度的經濟成長,則一來一往,一上一下之間,中、美兩國國力的消長,地位的互易,態勢定矣。指標性的事件,將是中國是否能在2025前後登陸月球;而美國是否或何時正式宣佈中止登陸火星的「計劃」。

或許,2020 - 2030年代將是「美國時代」和「中國時代」的分水嶺。
