Peggy Whitson is welcomed to earth after a mission duringwhich she conducted five spacewalks and set a new record in Americanspaceflight.
After a one-hour re-entry, outgoingspace station Commander Peggy Whitson (in AP photo above), cosmonautYuri Malenchenko and Korean spaceflight participant, So-Yeon Yi, havereturned to Earth, landing in Kazakhstan far off target.
"The good news is that the crew is OK," NASA commentator Rob Navias said.
"Crew members are reported in good spirits as well as in good health," added NASA commentator John Ira Petty.
The steeper than normal landing path subjected the crew to up the 10 times the force of gravity. U.S.flight surgeons are on the scene examining the crew. Russian spaceagency officials said the cause of the off-target landing would beinvestigated.
TheSoyuz landed about 295 miles short of its landing zone, delaying therecovery by about 45 minutes. The cause of the missed target was asteeper than anticipated re-entry angle, called a ballistic re-entry.Malenchenko called mission control with a satellite phone to saythe crew was well.
There had been at least two similar landings, Expedition 6 and Expedition 15.
One of the helicopters stationed along the projected landing zone quickly found the capsule. (Seen in the AP photo below).
Whitsonand Malenchenko, who spent 190 days in space, must  begin physicalrehabilitation. Yi returns after a nine-day stay and will not feelserious effects of prolonged microgravity.
Aparachute deployed to slow the final descent, and rockets fired whenthe capsule was just a few feet above ground, cushioning the contactwith the ground.
Afterher latest six-month stay, Whitson has a total of 377 days in space, arecord for U.S. astronauts. On four flights, Malenchenko has more than500 days in orbit. Malenchenko and Whitson blasted off Oct. 10, 2007.

俄罗斯联盟TMA-12号载人飞船周六（4月19日）返回地球，但降落地点与原定目标相差超过400公里。

俄罗斯官员表示，飞船着陆前向降落点派出了紧急直升机，所有飞船组员均安然无恙，仅在飞船进入地球大气层时承受了猛烈的重力加速度力冲击。

联盟TMA-12号的着陆位置距离原定的哈萨克大草原降落地点420公里远。

观察这次着陆的专家指出，宇航任务的工程人员均会尽量准确计算着陆的位置，出现这样大误差相当罕见。

飞船返回地球的时间也比较预期的迟20分钟。

这次飞船前往在国际空间站的任务历时十一天，本次飞行也是韩国第一次派出宇航员参与太空任务。

29岁的李素妍与两名俄罗斯宇航员一起乘坐联盟TMA-12号载人飞船与国际空间站对接。

（法新社邁阿密十八日電） 美國航空暨太空總署（NASA）希望將來登陸月球的太空人，能在上面待得久一點。


NASA先進技術部主任華茲表示，他們希望能在月球上建立基地，提供精密的交通工具和電力系統，讓太空人長住六個月。


他表示，NASA正在審核不同的月球前哨站設計圖。而這些設計可以從環繞地球軌道運行的國際太空站得到啟發，


這位資深太空人在邁阿密大學一場有關NASA未來發展論壇中提到：「我們需要在月球上擁有更長的停留時間，甚至達到六個月，就如同我們待在國際太空站的時間一樣。」


「我預測我們會打造類似於目前為國際太空站所作的設計，但有些地方可能會不一樣。」


國際太空站雖然可以讓很多科學家停留，但通常都保持在三人左右。這些太空人搭乘NASA的太空梭出任務，到太空中進行軌道實驗。


美國太空官員計畫在二零二零年前重新回到月球，並在月球表面建立永久觀測站。


華茲表示，他們還需要設計月球表面專用的交通、通訊和電力系統，同時能允許太空人離開基地，進行各項科學研究。


他說：「我們將生活在月球上，在上面工作、建立基地，同時使用它的資源。」

英國維珍銀河公司的「太空船二號」（SS2）計畫進行順利，今夏即可載客試飛，並有一對情侶定下明年的太空之旅，打算來場太空婚禮，而維珍集團老闆布蘭森也可望成為主持太空婚禮的第一人。

維珍銀河公司發言人表示，目前訂位者有兩對喜氣洋洋的客人，一對計畫進行太空蜜月、一對是在天願做比翼鳥的情侶，計畫在地球上空11萬公尺定終身。

維珍的太空觀光票價昂貴，每人要20萬美元（約台幣606萬元），但已有200多人付了訂金以確定機位，還有8萬多有興趣乘坐SS2一圓太空夢的人進行登記。

將在SS2處女航度蜜月的是維珍銀河公司顧問懷塞德和新婚妻子蘿芮塔。至於第一對太空新人是誰，維珍銀河並未透露，但布蘭森可能取得臨時執照來主持婚禮。

這不是58歲的布蘭森第一次客串「牧師」，去年他在網路教會取得授權，在舊金山飛拉斯維加斯的維珍客機上，為維珍的美國行銷主管帕帕鐸諾納斯主持空中婚禮；據說Google創辦人佩吉在加勒比海小島結婚，布蘭森也幫忙主持。

維珍銀河公司今年1月展示了SS2號模型，讓太空旅行進一步接近實現。SS2號由兩名飛行員駕駛，可搭乘六名乘客，先由運載飛機「白色騎士二號」載至1萬 5240公尺高空，SS2 脫離母機後發射火箭，以音速三倍的高速直線上升，至11萬公尺後減速滑行，乘客可經歷約五分鐘的無重力狀態，並欣賞地球景色。下降時，乘客可一嘗30秒的 6g重力的滋味，整個行程預計約兩個半小時。

維珍銀河目前還不確定太空旅行何時可以成行，但預計在明年第二季，第一年可運載500位太空觀光客。想一圓太空夢，除了要有錢，身體也要能承受得住6g重力才行，必須參加三天的訓練。

目前訂位的據說有美國影集「朱門恩怨」女星維多利亞普林西波、不良於行的物理學家霍金等。

No more funds for space programme
By IZATUN SHARI

KUALA LUMPUR: The Government will have to look for money if it wants to proceed with the next phase of the space programme, said Science, Technology and Innovation Minister Datuk Dr Maximus J. Ongkili.

He said in principle the Government wanted to pursue the next phase of the programme subject to funds available.

"Under the midterm review, I can say that there is zero money. If we want to proceed with the second phase we have to look for money," he told reporters Monday after the launch of the Creativity and Innovation Day 2008 celebrations at KL Tower here.

"So far, I am waiting for the results of an analysis report from the International Space Station on its costs and benefits before I go to my Cabinet colleagues for guidance and we can consider looking for money for the programme."

He reiterated that the space programme should not be viewed only in terms of sending angkasawan into space but also in terms of research undertaken involving other sciences besides astronomy.

He said the ministry would also have to consider other competing priorities particularly social development needs.

Asked when he expected to obtain the findings of the analysis report, Ongkili said: "I should be able to answer questions relating to the matter in Parliament by next week.

"We have to get fair views on the matter. I will use the opportunity to get views from MPs to see what they think of the programme," he added.

The first phase of the programme where angkasawan Dr Sheikh Muszaphar Sheikh Shukor and two other astronauts blasted into space in a Russian Soyuz 11 rocket from Baikonour, Kazakhstan, on Oct 10 last year was partly funded by the offset purchase of Sukhoi SU30MKM fighter jets from the Russian Government.

Ongkili also said the National Science Centre would be corporatised before the end of the year to give the division autonomy to make its own decisions.

"Under the midterm review, we want to look at this. Within the next six months we should be ready with the blueprint."

No cause has yet been determined for a second off-target, ballistic Soyuz landing in a row.

Teams from NASA and the Russian space agency will shortly begin investigating the cause of the apparent re-entry system failure.

"It's going to take several days for them to get (the capsule) back to Moscow," said NASA spokesman Nicole Cloutier. "It does have a flight recorder."

On Saturday, a Soyuz capsule carrying U.S. astronaut Peggy Whitson, cosmonaut Yuri Malenchenko and South Korea spaceflight participant, So-Yeon Yi, had a technical problem and fell to Earth like a rock, landing some 260 miles off course. The landing came after a steeper-than normal re-entry caused the crew to endure dangerous forces 10 times that of gravity and twice the normal re-entry pressure.

A Soyuz spacecraft automatically makes a ballistic re-entry if its guidance systems fails. Cosmonaut Yuri Malenchenko confirmed that the craft automatically made the switch to the emergency re-entry system, but he could not say why.

"There was no action of the crew that led to this," Malenchenko
said. "Time will tell what went wrong."

Though tough on the crew, a ballistic re-entry is relatively safe, said U.S. space station program manager Mike Suffredini. A similar
re-entry affected the last Soyuz return in October 2007, which carried two cosmonauts and a Malaysian space tourist.

There has been no talk of grounding the Soyuz fleet.

"It's still a functional spacecraft. The incidents don't rise to
the level of requiring a stand down," said James Oberg, an authority on the Russian and Chinese launch systems and consultant for NBC News.

The Russians are preparing to increase their launch rate from two
per year to four per year to provide for a six-person crew on the expanded space station in 2009. Oberg questioned whether the production increase is responsible.

"Has doubling the production overstressed their production safety
and quality?" he asked.

Work to mate the external tank and the solid rocket boosters went well last week.

Processing work is ahead of schedule, so space shuttle Discovery's rollover to the Vehicle Assembly Building will be moved up a second day to Saturday at 8 a.m.

The rollover had been scheduled for April 28. After a launch delay of nearly a week because bad weather delayed the arrival of the external tank, Discovery is scheduled to launch May 31 on a mission to the International Space Station.

The shuttle will deliver a 35,000-pound laboratory module, the second section of a Japanese laboratory complex.

NASA: one to three months for Soyuz answer

NASA expects to wait one to three months for an answer to why a Soyuz space capsule dropped to Earth like a rock in an emergency landing, which might have been a repeat of a problem experienced during the last Soyuz re-entry.

The Soyuz that landed early Saturday had at least three problems: a possible repeat of a shorted hand controller cable that caused the capsule to go into emergency landing mode, a separation problem - perhaps a failed explosive bolt - with the final stages of the capsule and smoke in the cabin, which cleared when cosmonaut Yuri Malenchenko turned off the display lights.

NASA associate administrator Bill Gerstenmaier said the Russians have appointed a commission to investigate the incident. He expressed confidence the commission would learn why the Soyuz landed 260 miles off target after causing the crew to experience twice the normal forces of re-entry. However, U.S. astronaut Peggy Whitson, cosmonaut Malenchenko and South Korea spaceflight participant, So-Yeon Yi, have been reported in good condition.

"They are doing everything we would do. We will get good results from this," said Gerstenmaier. "We share data back and forth."

He would not speculate on what the troubling second emergency landing in a row could mean for the U.S. space program, which will rely on Soyuz capsules to transport crews to and from the space station when the shuttle stops flying in 2010.

"We need to just get through this investigation, and see what it implies about the future."

降落艙方向錯誤
3太空人好運逃死劫

（莫斯科23日綜合電）《國際傳真社》周二引述熟悉調查的消息人士的話說，3名太空人上周穿越大氣層返回地球時，很幸運地躲過危機生還。

報導引述消息人士的話說：“太空人沒有受傷，毫髮未損，非常幸運。結局原本可能更糟。”

他表示，太空人性命一度“危在旦夕”。

韓國第一位太空人李素妍及俄羅斯與美國同僚昨天表示，他們18日以非慣例的“彈道”方式返回地球之后，恢復情況良好。他們降落地點距離預定目標相差數百公里。

《國際傳真社》消息人士表示，俄羅斯設計的聯合號降落艙進入大氣層時，面對的方向錯誤，使得降落艙無法受到隔熱板保護。

報導引述消息人士的話說：“如果艙口被燒穿，附近的降落傘受損，太空人可能無法生還。”

李素妍在國際太空站9天之后，與滯留太空超過6個月的美國國家航空暨太空總署太空人惠特森及俄羅斯太空人馬林成科，一起返回地球。

The cause of a Russian spacecraft's fiery descent back to Earth on Saturday is still unknown, but investigators suspect an electrical short circuit or the delayed detachment of a propulsion module might be to blame, NASA's space operations director Bill Gerstenmaier said on Tuesday.

On 19 April, the Soyuz TMA-11 automatically switched to a "ballistic" re-entry mode while returning to Earth. This is a backup mode involving a steeper than normal trajectory; it exposes the crew to up to 10 times the force of gravity on Earth during descent.

On board the spacecraft were South Korea's first astronaut, So-yeon Yi, and space veterans Yuri Malenchenko and Peggy Whitson.

Mission controllers in Moscow lost radio contact with the capsule for about an hour during the descent and as a result were initially unaware that the ballistic re-entry mode had been triggered, or that the capsule had landed some 475 kilometres (295 miles) short of its target.

Saturday's ballistic re-entry is the second in a row for the Soyuz spacecraft and the third since 2003.

In a teleconference with reporters on Tuesday, Gerstenmaier downplayed reports of danger to the crew and urged patience as a commission set up by the Russian Federal Space Agency investigated the issue. "We don't see this as a major problem, but it's clearly something that should not have occurred," Gerstenmaier said. "We don't like to see things repeat on two flights."
Electrical short

Russia's Interfax news agency quoted an unidentified Russian space official as saying that the Soyuz capsule suffered significant heat damage and that the crew was in serious danger during descent. But Gerstenmaier said he was unaware of any such statements being made. "The Russian folks have not told me any of that," he said. "They're concerned about the event, but the relative danger to the crew – we've had no discussion on that at all."

The initial suspect for the problem is a cable that connects the control panel in the crew capsule to descent hardware on the Soyuz. An electrical short in the cable can automatically trigger the ballistic re-entry mode.

Such a short is suspected to have caused the ballistic re-entry experienced by a Soyuz spacecraft in October 2007.
Wrong orientation

Investigators of the earlier Soyuz TMA-10 mishap also found evidence of a delay in the detachment of a propulsion module from the capsule. If the module does not detach from the crew capsule as planned before hitting the Earth's atmosphere, it changes the weight distribution of the spacecraft, potentially causing the crew capsule to descend to Earth in the wrong orientation.

Initial reports from the crew of Soyuz TMA-11 suggests a similar detachment delay occurred during Saturday's re-entry. Russian investigators are exploring the possibility that the two events are linked, but Gerstenmaier cautioned against jumping to conclusions.

"That's not the right leap to make yet," he said. "Let the Russians go ahead and get the data, analyse and understand what they've got and then we can talk about where we are."
Critical time

The Soyuz mishaps come at a particularly crucial time for NASA. The agency is preparing to retire its shuttle fleet in 2010 and the replacement Orion Crew Exploration Vehicle (CEV) will not be ready until 2015.

During the five-year gap, the Russian Soyuz will be the primary vehicle for shuttling crew to and from the International Space Station.

Gerstenmaier said it is too early to speculate how the recent accidents will affect NASA's future, but hinted that the agency would consider commercial launch options if necessary.

"We don't have the luxury or the funding to go ahead and continue multiple launch systems," Gerstenmaier said. "We'll work as hard as we can to get our CEV or get a commercial crew transportation capability online as soon as we can."

Shuttle orbiter moves to assembly building


http://www.floridatoday.com/apps/pbcs.dll/section?category=news02

The orbiter Discovery is in the Kennedy Space Center Vehicle Assembly Building today after an early-morning move from its processing hangar.

The spaceship backed out of its hangar at 7:17 a.m. and then made the quarter-mile move to the 52-story assembly building, where it will be hoisted atop a mobile launcher platform and then mated to an external tank with attached solid rocket boosters. Discovery rolled into the VAB transfer aisle just after 8 a.m.

Discovery and seven astronauts are scheduled to launch at 5:02 p.m. May 31 on a mission to deliver the Japanese Kibo science laboratory to the International Space Station. The 17.5-ton lab will be moved out to launch pad 39A from the high bay at the Space Station Processing Facility on Monday. The fully assembled shuttle will roll out to the launch pad a week from today.

Whitson's parents describe landing-day tension


http://www.floridatoday.com/apps/pbcs.dll/section?category=news02

The Des Moines Register has a nice story today detailing Peggy Whitson's parents' experience when the Soyuz spacecraft bringing the astronaut back to Earth went off course and could not be found for almost an hour. Here's the introduction to the piece, which you can read in full by clicking the link at the end of the post.

Beth and Keith Whitson were up at 3 in the morning to watch their daughter's return from space.
They put on the coffee, turned on NASA's television station and waited. Way too long.
Peggy Whitson (pictured above above after recovery, courtesy NASA) had been living and working on the International Space Station nearly six months, but the last half hour was the toughest for this Ringgold County farm couple.
"She was supposed to land at 3:37, and it was after 4 before they confirmed that they had landed in Kazakhstan and we knew they were OK," said Beth.

欧洲伽利略卫星导航系统的最新一枚试验卫星在哈萨克斯坦拜科努尔发射升空。

这枚名为Giove-B的试验卫星由俄罗斯“联盟”运载火箭搭载，当地时间星期天（4月27日）清晨4点16分（格林尼治时间星期六22点16分）离开地球。

这枚样板卫星将测试伽利略计划的一系列重点技术，并最终用于建造30枚组成伽利略网络的运营卫星。

重0.5公吨的Giove-B是伽利略计划的第二枚试验卫星。欧洲宇航局在2005年发射了首枚测试卫星Giove-A。

这次Giove-B试验的重要焦点，是卫星内载有的三个时钟当中，惰性氢微波激射时钟在太空中的运行表现。

这是至今被送进太空最稳定的时钟，能保持时间准确度在每24小时不差于一纳秒（10亿分之一秒）。

连同卫星内的原子钟，Giove-B将测试在运行范围内产生时间信号的能力。这是所有卫星导航系统赖以运作的基础。

延误与资金紧张

对于经过多番延误的伽利略计划而言，Giove-B的升空有着十分重大的意义。

Giove-B卫星因为在最后升空准备阶段发生严重零件故障而滞留地面一年，但更大的问题是，伽利略计划已经发生过多次延误，更徘徊在被放弃的边缘。

欧洲联盟至今已经投放了16亿欧元（25亿美元）在这项计划上，部长们还警告，最近追加的34亿欧元卫星导航投资拨款将是整项计划的融资上限。

如果这次Giove-B试验的一切技术都一如计划般运作，欧洲将争取在2010年发射首四枚运营卫星。

欧洲当局期望，伽利略系统能在2013年底前全面运作。
