KUALA LUMPUR, June 5 (Bernama) -- Malaysia's astronaut candidates can train at the National Aeronautics and Space Administration (NASA) in the United States (US) to familiarise themselves with the American compartment at the International Space Station (ISS).

Science, Technology and Innovations Minister Datuk Seri Jamaluddin Jarjis said NASA had granted permission for Dr Sheikh Muszaphar Shukor and Kapt Dr Faiz Khaleed (the two candidates) to undergo the training from July 23 to 27.

"The permission is very important as our astronaut will shift from the Russian module to the NASA compartment at the ISS," he told reporters after attending a design recognition ceremony for local products here Tuesday.

Before going to the US, both men will fly back to Malaysia on June 18, he said.

One of the candidates will make the space journey scheduled for October and in the process make history by becoming Malaysia's first astronaut.

Meanwhile, Jamaluddin said Malaysia would step up research and development (R&D) efforts to improve on its commercial products to further enhance the economy.

He said the time had come for Malaysia to use "knowledge" as its new economic resource.

"Malaysia cannot be complacent anymore as China and Vietnam are now offering cheaper labour for foreign investors. The world has now shifted to China, India and even Vietnam," he said.

A total of 15 products of Malaysian design such as furniture and packaging items were awarded with the "Malaysia Good Design Mark 2006" as recognition by the Malaysia Design Council.

Jamaluddin added that the ministry was ready to allocate RM500 million for R&D, mainly to universities, and that the government had already engaged international consultants such as Boston Capital and Pricewater House Coopers to identify and develop strategies and markets for Malaysian design.

大马宇航员将会在7月尾在美国太空署进行为期5天的训练。

By Craig Covault/Aviationweek.com

China will postpone its first unmanned mission to the Moon by at least 5-6 months, a delay that under current scheduling means Japan will beat China to lunar orbit, with a far more ambitious triple-spacecraft launch in mid summer.

The Asian space race to the Moon is politically important in Asia-Pacific technology circles where China talks a good game, but Japan has produced far more concrete results, especially in space exploration.

The country that prevails with first lunar bragging rights will be noted in the region, where China is perpetually trying to spread influence at the expense of Japan.

China's new oxygen/hydrogen propulsion system development, needed for even more ambitious Chinese lunar missions, is also falling years behind schedule, U. S. intelligence analysts believe.

China had originally planned to launch its 5,000-lb. Chang'e lunar orbiter in April on an existing Long March booster. Beijing officials who had been touting the spring target for a year suddenly are announcing a September or October date at the earliest for their first Moon mission, as if the early spring target had never been on the books.

In contrast, the 6,600-lb. Japanese Selene lunar orbiter has been delivered to the Tanegashima Space Center for launch in early August on an increasingly important Asia-Pacific space mission.

These are not just "planning paper programs" decades from development, but advanced aerospace projects involving thousands of engineers in both countries. By using advanced aerospace technologies, Japan has developed the most ambitious lunar mission since the end of the U. S. Apollo lunar program in 1972 and the final Soviet unmanned sample return flight in 1976.

And Selene is far more complex than the Chinese flight. The Japanese vehicle is a triple-spacecraft mission with a 16-ft.-tall mothership, the largest unmanned spacecraft ever sent to the Moon. Selene is only a few feet shorter than the Grumman Apollo lunar modules that landed astronauts on the surface.

中国的登月行动将会推迟到9月以后。
日本的登月行动如没有意外， 8月初就可以发射到月球了。
作者比喻亚洲的登月行动是政治主导。

首先发射到月球的国家将会有更大影响力。
北京尝试用登月行动来扩大其影响力，
并减低日本对本区域的影响。

ST. LOUIS, June 08, 2007 -- The Boeing Company [NYSE: BA], through its commercial launch business, successfully launched the first of four Italian Constellation of Small Satellites for Mediterranean basin Observation (COSMO) SkyMed spacecraft June 7 aboard a Delta II rocket.

Lift-off occurred at 7:34 p.m. Pacific time from Pad SLC-2W at Vandenberg Air Force Base, Calif. A Delta II 7420-10 configuration launch vehicle deployed the COSMO-SkyMed spacecraft to low-Earth orbit approximately 58 minutes after liftoff.

"We are pleased to provide launch services for Thales Alenia Space Italia, the Italian Space Agency and the Italian Ministry of Defense," said Brewster Shaw, vice president and general manager, Boeing Space Exploration. "Congratulations to the COSMO-SkyMed launch team on a job well done. Boeing is honored by the opportunity to be a part of this exciting mission with the successful lift into space provided by the United Launch Alliance Delta II, a vehicle with a long Boeing history."

The COSMO-SkyMed launch is the first Boeing commercial Delta II launch since Feb. 11, 2002, when Boeing launched five Iridium satellites from Vandenberg Air Force Base.

Thales Alenia Space Italia, which provides Delta II tanks to Boeing, developed the COSMO-SkyMed program for the Italian Space Agency and the Italian Ministry of Defence. It is an end-to-end Earth observation dual-use (civil and military) system composed of four medium-sized satellites and supporting ground stations for orbit control systems and data reception and processing. The system will take imagery of the Earth using an X-Band Synthetic Aperture Radar instrument capable of operating in all visibility conditions at the request of institutional and commercial users, including members of the civil, scientific and military communities.

美国“阿特兰蒂斯”号航天飞机8日升空后，机上宇航员在检查机身隔热板时发现一条裂痕。由于担心类似“哥伦比亚”号航天飞机的悲剧重现，这个发现引起高度关注。地面控制中心的专家对发送回来的照片分析后认为，这个裂痕不会影响航天飞机安全返航。

裂痕长约10至15厘米

　　“阿特兰蒂斯”号航天飞机美国东部时间8日19时38分(北京时间9日7时38分)从佛罗里达州肯尼迪航天中心发射升空。机上宇航员随后检查机身时拍到的照片显示，“阿特兰蒂斯”号外侧隔热板有一条裂痕。

　　据美联社报道，这个裂痕位于“阿特兰蒂斯”号左侧隔热板，长度约10至15厘米。8日晚至9日晨，宇航员使用机械臂检查了这个裂痕，用拍摄装置拍下裂痕的照片，传给航天中心的专家进行分析。

　　宇航员帕特里克·福里斯特在9日的例行检查中继续查看航天飞机外侧的隔热板，包括机头和机翼的尖端。美国宇航局(NASA)发言人凯尔·赫林说，截至9日晚，还没有发现其他问题，“阿特兰蒂斯”号飞行顺利。

　　负责这次飞行的小组负责人约翰·香农10日在新闻发布会上说，可能是由于空气将隔热板的一角掀起，致使出现这个裂痕。“目前这不足以引起顾虑，但是依然有许多工作要做。除此之外，航天飞机一切正常。”

可在太空行走时修复

　　尽管如此，地面控制中心的工程师仍将认真研究“阿特兰蒂斯”号隔热板上的裂痕，以避免类似“哥伦比亚”号航天飞机的悲剧重现。

　　“哥伦比亚”号航天飞机2003年2月返航时，因外挂燃料箱绝缘泡沫脱落发生解体，机上7名宇航员全部遇难。

　　地面控制中心的工程师将仔细研究从航天飞机上传送过来的照片，包括裂痕的照片和航天飞机尾部引擎的照片，尤其是安装在固体火箭推进器上的拍摄装置拍下的照片。工程师能借助这些照片构建三维模型，并通过空气动力学和热力学测试判断被掀起的隔热板是否会妨碍“阿特兰蒂斯”号成功返航。

　　此外，工程师们还计划研究此前的航天飞机飞行纪录。“发现”号航天飞机曾于2005年和2006年出现2次隔热材料脱落的情况，但是没有影响返航。“阿特兰蒂斯”号航天飞机也在此前2次飞行中出现隔热板脱落情况，与这次裂痕所处位置相同。

　　据美联社报道，NASA目前并不认为被掀起的隔热板所处位置能引发致命问题。航天飞机返回地球时，这一位置所受温度最高不会超过540摄氏度，而其他部分可能经受1600摄氏度高温。

　　尽管如此，如果工程师认定这个隔热板需要修理，“阿特兰蒂斯”号上的宇航员可以在太空行走时修复这块隔热板。“哥伦比亚”号悲剧发生后，所有航空飞机执行任务时都要求携带一个修理工具箱。

国际空间站将换人

　　“阿特兰蒂斯”号的升空是美国宇航局今年首次发射载人航天飞机。“阿特兰蒂斯”号载有7名男宇航员，由里克·斯图科率领。本次飞行将为期11天，任务是继续建设国际空间站，为国际空间站带去一个新组件和一对太阳能电池板。

　　据美联社报道，“阿特兰蒂斯”号目前正沿着轨道每90分钟飞行一周，绕行一周后和国际空间站的距离就缩短了1300公里。

　　这个过程具有很高的危险性，香农说：“两个飞行器重约104吨，还以约28162公里的时速飞行，这实在有点困难。”尽管如此，这一被NASA官员称为“优雅芭蕾”的对接过程此前20次均获成功。

　　按计划，“阿特兰蒂斯”号将于美国东部时间10日15时38分(北京时间11日3时38分)与国际空间站对接。

　　对接完成后，航天飞机将和国际空间站一起飞行，直至本月17日。在此期间，宇航员计划进行3次太空行走，分别在1日、13日和15日，为国际空间站安装新组件及收回旧太阳能电池板。

　　此外，宇航员克莱顿·安德森将于17日代替苏尼塔·威廉斯，留在国际空间站担任美国宇航员代表。已经在国际空间站生活了6个月的威廉斯当天将搭乘“阿特兰蒂斯”号返回地球。(来源：新华网)

Press Trust of India
Sunday, June 10, 2007 (New Delhi)
India will launch its first dedicated military satellite in August to give the country the capability to monitor missile launches in its neighbourhood.

The dedicated military reconnaissance satellite, CARTOSAT 2A, will be launched on a Polar Satellite Launch Vehicle rocket by the Indian Space Research Organisation (ISRO) in the first week of August, an official said.

CARTOSAT 2A will boast of spatial resolution and will be loaded with cameras that can supply advanced imagery. It will cater to military and intelligence specifications than any existing Indian satellite.

The launch of the satellite will fulfill a long- standing demand from the armed forces for a dedicated reconnaissance spacecraft.

Launch of the first military satellite will be rapidly followed by the launch of two more advanced imaging satellites by next year to give India the capability of keeping an eye round-the-clock on the region surrounding the country.

The first military satellite will have an Israeli synthetic aperture radar that can take pictures of the earth through cloud and rain round the clock.

With three advanced reconnaissance satellites in orbit, Indian military agencies will have the capability to keep an eye on the airspace over Pakistan and China, to study the oceans and monitor changes in winds across the seas.

Network-centric platform

India currently has in orbit three dual-purpose satellites - CARTOSAT-I, CARTOSAT-II and the Technical Experiment Satellite - that are used by the country's space agency and the military.

The launch of CARTOSAT 2A has been timed to coincide with the scheduled delivery of the country's first airborne warning and control system (AWACS) aircraft by Israel to give the armed forces a network-centric platform for carrying out surveillance from the ground to the stratosphere.

However, the supply of the Phalcon AWACS aircraft has been delayed by a few months.

The launch of the military satellite is also being undertaken in tandem with the Indian Air Force's plan to set up an integrated air command, control and communication system.

The plan envisages the linking of the AWACS, Aerostat balloon-borne radars and low-level transportable radars of the IAF with the dedicated military satellite.

Israel Launches Advanced Spy Satellite

Israel successfully launched an advanced spy satellite into orbit Monday, giving it a sophisticated new tool in its efforts to collect intelligence on archenemy Iran and other regional adversaries.

Israeli space officials said the Ofek-7 satellite can pick up even small objects from space, and that information will be shared with the United States.

Ofek-7 was launched from a beach front air base south of Tel Aviv before dawn, the bright flame from its booster rocket lighting up the beach and ocean on a clear night and the roar of its engines heard more than 10 miles away.

Senior officials from Israel's space program said the satellite will significantly improve Israel's intelligence capabilities, allowing it to view objects as small as an average TV set.

"It's true that this helps the Iranian issue," Haim Eshed, chief of the Defense Ministry's space department, told Army Radio. "And it's clear above all else that this satellite is a very significant addition to the ability to gather intelligence."

Israel considers Iran its main strategic threat, charging that Iran's nuclear program is designed to build atomic weapons. Iranian President Mahmoud Ahmadinejad has said repeatedly that Israel should be "wiped off the map." Iran insists its nuclear program is for peaceful purposes.

The new satellite is "one of the most sophisticated in the world" and will operate with the existing Ofek-5 to provide different viewing angles, said Yiftah Shapir, a military analyst at the Institute of National Security Studies. "This will enhance Israeli capabilities to monitor any threat from anywhere in the region, whether its Lebanon, Syria or Iran," he said.

Ofek-5 is already past its projected life span, pressed into additional service with the failure two years ago of the launch of Ofek-6. "Ofek" is the Hebrew word for "Horizon."

The satellite weighs 66 pounds and is 7.5 feet long, said the chairman of the Israel Space Agency, Isaac Ben-Israel. It is significantly lighter than the most advanced American satellites, which have similar capabilities but weigh at least three tons, he told Army Radio.

Ofek-7 was launched 310 miles into the sky from an air force base at Palmachim, south of Tel Aviv, Army Radio said.

Though the U.S. has its own spy satellites, Ben-Israel said it was in the interest of both Israel and the U.S. to exchange intelligence. "There is no country in the world, not us and not the Americans, that is able to obtain everything alone," he told Army Radio.

"If you have something that they don't have and if they have something that you don't have, you make an exchange."

The satellite can view objects as small as 28 inches long, Army Radio said. But Ben-Israel said the resolution was even better, saying the objects it can discern are "a few dozen centimeters" long.

The Ofek-7 uses optical technology, meaning its viewing ability is limited by clouds and nonexistent at night, Shapir said. By 2010 Israel is expected to launch another spy satellite with radar technology that will overcome these limitations, he said.

Ofek-5 and Ofek-7 are the only two Israeli spy satellites, Army Radio said. Israel also has two commercial satellites.

Secret Spaceflight Readied At Cape Canaveral

Jun 13, 2007

By Craig Covault/Aviationweek.com

Two top secret National Reconnaissance Office/Navy ocean surveillance spacecraft to track terrorist movements at sea are being readied for launch from Cape Canaveral June 14.

The government will discuss the launch and satellite mission only generally, but details gleaned from intelligence sources were reported April 30 in Aviation Week & Space Technology.

Liftoff from Cape Canaveral's Launch Complex 41 is planned between 11:18 a.m. and noon EDT on board a nearly 200-ft.-tall U.S. Air Force Atlas V Evolved Expendable Launch Vehicle.

The rocket was scheduled be rolled to the launch pad late June 13. The loading of tons of kerosene and liquid oxygen and hydrogen propellants will begin early June 14.

There is a 70% chance weather for the launch will be favorable, according to the Air Forceýýýs 45th Space Wing, which is managing the launch in connection with Lockheed Martin and United Launch Alliance.

One unusual aspect of this secret U.S. military flight is that the Atlas V is powered by Russian RD-180 engines designed during the Cold War.

The importance of NRO's ocean surveillance role, which it coordinates with the Navy and Coast Guard, has been elevated since the Sept. 11, 2001, terrorist attacks. And it is likely that Air Force fighters will fly patrols near the launch site to guard against any airborne terrorist attacks on the mission itself. Air Force F-22s were used for the first time for protection of the space shuttle prior to its launch June 8.

The need to track thousands of civilian ships worldwide has intensified given the potential for seemingly harmless shipping to be involved in nuclear, chemical or biological terrorist operations. Also, potential adversaries like China and Iran are demonstrating new sea-based tactics and capabilities that must be monitored.

The National Ocean Surveillance System (NOSS) flight, designated NRO L-30 will track such terrorist operations at sea as well as provide data on Chinese and Iranian ship tactics. Although classified top secret, the mission insignia is painted several feet tall on the Atlas V nose shroud. It shows a 19th century clipper ship under full sail viewed from above, as a satellite would see it.

The two satellites on the Atlas V mission have a combined mass of about 6.5 tons and will use primarily electronic intelligence (elint) techniques combined with interferometery. The technique involves comparing the differences in the elint data from each spacecraft to derive accurate position and direction of travel data.

The U.S. Naval Research Laboratory in Washington, D.C., plays a key role in the mission. The spacecraft and launcher combined have a total cost of $600-800 million.

The satellites will fly in formation in an elliptical orbit that is precisely controlled to obtain data at different times as they overfly specific ships, so that the vessels movements can be detected and tracked.

Those data will then be combined with information from about 18 other NRO ocean surveillance satellites spaced in six or seven formations orbiting the globe.

After liftoff, the Atlas V will fly a trajectory northward along the U.S. East Coast. Viewers as far north as the Virginia coast should be able to see the Atlas V rocket plumes if weather conditions are favorable in their areas.

（东京综合电）日本宇航研究所(JAXA)昨日宣布，日本为发射日本首个绕月探测器所作的准备工作，一切相关系统都完善，预计日本将能如期在8月16日发射这个名为“月球工程探索者号”（SELENE）的探测器。

　　该研究所说，此个月球探测器将由H-2A火箭运送升空，发射地点是在日本南部的种子岛。此计划已耗资320亿日元（约4亿零400万新元），而且已延后了4年。此前，日本曾在1990年发射一枚探月火箭，但当时只是进行接近月球轨道的飞行，此次将进行的是绕月飞行。

　　日本宇航研究所说，这是自美国启动阿波罗计划以来世界最大的探月计划。此计划采集的月球数据将用来研究月球的起源和演变过程。

美国亚特兰蒂斯号航天飞机将延长其太空任务，以便修复受到损毁的隔热层。

美国宇航局的官员们周二（6月12日）说，亚特兰蒂斯号的太空任务将由原定的11日延长到13日，以便宇航员能够修复在升空时被掀起的一块隔热层。

他们说，将在宇航员的第三次或额外的第四次太空步行时修理在航天飞机尾部附近的隔热层。

宇航员将离开航天飞机，走到受损的隔热层，然后通过机器臂进行修理工作。

工程人员相信，这块隔热层在起飞时受到空气动力的影响。

美国宇航局说，他们又100%的共识，在隔热层下未能确定的工程分析和潜在的破坏是不能接受的，，并应该尽可能进行修理。

工程人员不认为重返地球时的热力能够烧损毁隔热层下面的石墨结构和危害机上宇航员的生命，但他们担心受损的隔热层可能成一些破坏，需要在地面进行维修。

亚特兰蒂斯号的两名宇航员周一（6月11日）进行了太空行走，为国际空间站安装新的太阳能电池板，但太空行走比预定时间晚了几个小时，原因是保持空间站平衡的四个陀螺仪负载过量。

在2003年，哥伦比亚号航天飞机在升空时造成的机身损坏，使得它重返地球时发生事故，机上七名宇航员全部罹难。

Computer crash hits space station
International Space Station Image: Nasa
The failure affected Russian computers on the ISS
Russian computers controlling the International Space Station's (ISS) orientation and supply of oxygen and water have failed, Nasa officials say.

The station's three crew and seven visiting shuttle astronauts are not at any immediate risk; the ISS has not lost all vital systems.

But it could force Nasa to extend the current shuttle mission by one day.

Engineers are unsure why the computers stopped working as a failure of this type has not occurred before.

The US space shuttle Atlantis docked with the orbiting outpost at the weekend to begin its latest mission.

Nasa's space station chief said he expected the problem to be fixed within the next few days.

"We have plenty of resources, so we have plenty of time to sort this out," said Mike Suffredini, ISS programme manager for the US space agency.

Without the Russian oxygen machine running, the space station has a 56-day supply of oxygen left. "If we are in that position, we have an option to depart," Mr Suffredini said.

Different scenarios

The station's Russian segment has a network of six computers, but on Wednesday, only two were functioning.

The computers have experienced problems before, but a system-wide re-boot usually solved the problem.

This time, the system has been unable to re-boot.

Astronauts have finished the shuttle mission's second spacewalk
Under a worst-case scenario, where the computer problem persists beyond the shuttle's stay, and attempts to resolve it come to no avail, the station's three crew members could be forced to return to Earth early, the website Space.com reported.

The ISS is currently relying on its four gyroscopes to maintain its orientation in space, then shifting to using thrusters aboard the shuttle Atlantis when the gyroscopes are overwhelmed.

This dependency on the shuttle has caused Nasa managers to consider an extension of one day to Atlantis' 13-day mission.

If this goes ahead, the crew will have to conserve supplies - the shuttle mission has already been extended by two days in order to carry out repairs on a torn thermal blanket.

The crew of space shuttle Atlantis were originally due to spend 11 days at the ISS.

The mission was extended to 13 days in order to carry out repairs on a 10cm (4in) section of thermal blanket which peeled back as the shuttle blasted off from Cape Canaveral on Friday.

The blanket protects the shuttle from the intense heat of re-entering the atmosphere.

Russia-side ISS Computers Shut Down

Jun 15, 2007
By Frank Morring, Jr./Aerospace Daily & Defense Report

The two cosmonauts on the International Space Station (ISS) shut down the computers on the Russian side of the orbiting facility June 14, deferring by a day work to restore critical command and navigation systems that crashed June 13.

Loss of the Russian-side computers, which actually were built in Western Europe, could force an evacuation of the station, although managers considered that unlikely and certainly undesirable.

"We're always in a better [configuration] if we can keep the crew around to help us out," said Mike Suffredini, NASA's ISS program manager.

The Russian computers control the station's reaction control thrusters, which are needed for attitude control when the station's control moment gyros (CMGs) are saturated or otherwise unable to perform as needed. As long as space shuttle Atlantis is docked to the station, its thrusters can maintain attitude when the CMGs are unavailable, but the orbiter must land late next week when its supply of cryogenic oxygen for its fuel cells gets low.

Mission Control Center-Moscow (MCC-M) managed to restart one "lane" of the three data paths to the Russian Service Module Terminal Computer (TVM) and to the Russian central computer early June 14 while the station was in line with ground stations on Russian territory. With the computers up, controllers reconfigured station circuits to route power from the U.S. arrays into the underpowered Russian Zarya and Zvezda modules, and restarted critical life support units in the modules.

They also were able to put the three-seat Soyuz capsule that serves as the lifeboat for the full-time station crew back on station power, after running it on batteries overnight to conserve Russian-side power.

But after seven minutes the computers crashed again, and subsequent efforts to restart them came to naught. At about 1:15 p.m. EDT June 14, MCC-M ordered Expedition 15 commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov to switch off the computers for the day.

William Gerstenmaier, associate administrator for space operations, said it will take some time to complete troubleshooting and fix the problem, given the complexity of the station and the difficulty of finding a problem that may be due to some unforeseen interaction between U.S. and Russian systems. Possibilities include power quality from the new S4 solar array being activated during the ongoing STS-117 mission, electromagnetic interference from a new local area network cable strung outside the Zarya module during a June 6 spacewalk, or some sort of software anomaly.

In addition to troubleshooting, experts in Houston and Moscow were working on alternate ways to maintain station attitude control once Atlantis leaves. One promising approach would use the CMGs as much as possible, and the thrusters on docked Russian Progress cargo vehicles when they become saturated.

"I would say there is an extremely remote chance that this problem would lead to abandoning the space station," Gerstenmaier said. Still, shuttle mission managers were considering the option of extending Atlantis' stay at the station as long as possible, while the flight crew was cutting off unneeded systems to conserve power and consumables.

Repairs ease space mission woes

Friday's spacewalk was the current mission's third
Problems dogging a mission to the International Space Station have been eased following a space walk and a computer reboot.

A third spacewalk by astronauts on the shuttle Atlantis has fixed a tear in its thermal blanket that occurred during lift off.

And Russian cosmonauts have now successfully rebooted vital ISS computer systems that had crashed.

The systems control the station's positioning and its oxygen supply.

While the system was down, the ISS was relying on its four gyroscopes to maintain its orientation.

Lynette Madison, a Nasa spokeswoman in Houston, said the computers were "up and operational and this is good news for all".

Russian Mission Control chief Vladimir Solovyov said engineers had to disconnect the Russian oxygen-generating system, called Elektron, during repairs as it is dependent on the faulty computers. The lives of the crew were not in danger.

Russian space officials had said they were considering sending their cargo vessel Progress to the ISS earlier than scheduled to deliver spare parts for the computers if the problems persisted.

Mission extension

Meanwhile Atlantis crew members Jim Reilly and Danny Olivas embarked on the mission's third spacewalk.

The six-hour walk repaired damage to the shuttle's heat shield.

The astronauts used a medical stapler to seal a gap about the size of a human hand between sections of thermal insulation.

The blanket section had peeled back as the shuttle blasted off from Cape Canaveral on Friday.

The blanket protects the shuttle from the intense heat of re-entering the atmosphere.

Damage to the shuttle Columbia in 2003 during its launch led to the vehicle's disintegration as it returned to Earth, killing all seven crew.

The crew of Atlantis were originally due to spend 11 days at the ISS, but the mission has since been extended to 13 to carry out the thermal shield repairs.

This was supposed to be the second shuttle mission of 2007, but a freak storm over the Florida launch site in late February caused hail damage to the shuttle and delayed the mid-March flight.

Despite the delays, managers are confident they will be able to complete the ISS before the shuttles' 2010 retirement date.

Nasa plans to fly 15 more missions to the station to deliver large components, spare parts and other supplies. In addition, one final servicing call to the Hubble Space Telescope is planned for September 2008.

A spheroid Soviet-era space capsule has been sold for 72,000 euros ($96,000; £48,600) at an auction house in the French capital, Paris.

The Photon capsule spent two weeks on a scientific mission in space. The exact dates it was in flight are not known.

The spacecraft measures 2.7m (8ft, 10in) in height and has a diameter of 1.6m (5ft, 4in).

It was acquired by a private French buyer at the Drouot auction room, French news agency AFP reports.

Perfect' Ofek 7 already almost fully operational
By YAAKOV KATZ



Ofek 7, the new IDF satellite launched on Sunday night, began transmitting images back to Israel on Thursday.

Senior defense officials said the satellite would break a world record and be declared operational by the end of the week.

Israel's most advanced satellite, Ofek 7 orbits the Earth every 90 minutes from altitudes of up to 600 kilometers.

It has a projected four-year life span and joins the Ofek 5, launched in 2002, which is expected to stop working by the end of the year.

Security officials said all of Ofek 7's systems were functioning as planned and that Israel was pleased with the results thus far. The officials would not discuss the quality of the pictures being transmitted because of the secret nature of the contents.

Lt.-Col. Y., commander of the satellite command and control center, said Ofek 7's high-resolution images increased Israel's operational capabilities.

He said that the satellite's systems were working perfectly and that it would be possible to declare it operational by the end of the week. A satellite is usually declared operational after a month of tests.
