大家最近有留意到 Boeing 和 Lockheed在美国军事市场竞争激烈。
而且 Boeing 常成为输家。。。

基本上美国第五代战机的和约都给Lockheed拿掉了。

不过Boeing的市场也不小，很多运输机，直升机和外销的战机，都是Boeing由生产的。

俄图154客机外国多弃用 问世38年肇30空难 2006/08/23 18:10:54
●南洋商报


（莫斯科23日综合电）在乌克兰坠毁的俄罗斯图154 客机，自1968年面世以来，涉及最少30次空难。这种飞机中国4 年前已全面停用，但仍然是俄罗斯及前苏联加盟国的主要民航交通工具，俄罗斯一半的旅客每天乘搭这款飞机来往各地。

中国也曾拥有31架图154 客机，该款客机曾服务中国15年，但在2002年10月全面被淘汰，当中不少卖回俄罗斯。中国弃用图154 客机，据称是因为考虑到其安全性及性能都比欧美客机低，而且耗油量和维修成本较高，机件供应亦得不到保障。

日久失修忽略安检

图154 是一种三引擎的中程客机，由前苏联图波列夫设计局研发，用以取代图104、伊尔18 等旧式客机。当年前苏联标榜它是该国第一种按西方标准设计的客机，声称与美国波音727 客机及欧制三叉戟客机并驾齐驱。

专家认为，图154 系列庞大机队在前苏联解体后便日久失修，更因财政紧绌而屡屡忽略安全检查，因此经常成为空难主角。

廉价航空方兴未艾 服务品质有待改进
■日期／Sep 18, 2006   ■时间／12:45:55 pm
■新闻／财经前线   ■作者／本刊尤美慧

【本刊尤美慧撰述】廉价航空业的发展如火如荼，让更多人可翱翔天空；俯瞰香港丽江夜景不再是当年的童话、就连欧洲的爱丁堡也变得近如毗邻。过去两年时间里，至少有六家新的廉价航空公司投入运营。不久前，又一家廉价航空公司――香港甘泉航空公司（Oasis Hong Kong Airlines）宣布成立，并开通香港至欧洲的航线。



马来西亚的亚洲航空公司（Air Asia，简称“亚航”）启航，或是爱旅游者的福音，因为它创造了一个诚如亚航口号：“现在，人人都可飞”（Now Everybody Can Fly）的局面。在西马半岛工作的沙砂二州同胞，每年往返两地五、六趟，已经见怪不怪。不仅如此，在新加坡谋生的马来西亚人精打细算乘搭柔佛州航班回乡。



新加坡作为亚太地区一个重要的航空枢纽，是廉价航空的必争必驻之地。新加坡的廉价低成本航空公司（Low Cost Budget Airline）有捷星亚洲（Jetstar Asia）、新加坡欣丰虎航空(Tiger Airways，简称“虎航”)、惠旅航空公司（Valuair）及Silk Airline。  



马新廉价航空抢攻中国市场

亚航抢先开辟中国市场，在澳门设立基地后，吉隆坡直飞澳门的票价低至马币79.9元（不含相关税费）。期间，亚航也推出“买一送一”优惠，乘客需购买单程票却能享受双程机票。除了澳门以外，亚航早期推出的吉隆坡至厦门的航线现在却不见踪影了。

继亚洲航空进入中国内地后，第二家外资廉价航空，虎航在本年度四月开通深圳至新加坡、海口至新加坡及广州至新加坡航线，在短短三天内开通三条航线！三地最低单程票价统一为61.98新元，约合人民币143元（不含相关税费）。虎航从新加坡起飞至中国的航线，至今有广州、海口、深圳及澳门航线。

Silk Airline在大陆主要提供新加坡飞往成都、重庆、昆明、深圳及厦门的航线，较晚进入中亚航空市场的惠旅航空，则主攻另两个国际大都市，提供新加坡直飞香港和台北航。

在诸多外资廉价航空进入中国内地，大陆航空企业业者怎能休呢？春秋航空有限公司是中国首家获民航总局批准筹建民营航空公司的旅行社。春秋航空在今年一月份启航后，一度暂停航线，但已在7月18日恢复运作。春秋航空率先在中国设立网上订购机票，并与上海春秋国际旅行社有限公司设立春秋航空旅游网，以电子商务方式提供快捷航空票务、旅游和酒店等在线预订服务。



春秋航空的市场定位是“旅游者和对价格比较敏感的商务旅客”。通过学习美国西南航和爱尔兰瑞安航等世界著名低成本航空公司的运营模式，为广大旅客提供低价及便捷的航空运输服务。恢复运作后，春秋航空目前主要发展其国内业务，提供乘客从上海出发的航班。启航不到一年的春秋航空，正常执行了136个航班，平均客座率99.79%，已经超过了运行前制订的平均客座率85%的目标。



廉价航空终站推动廉价航空业



廉价航空为何能在价格上有如此大的竞争力，无庸讳言廉价航空终站是其中一大因素。吉隆坡机场廉价航空终站（LCCT-KLIA）今年三月开幕，这个耗资马币1亿零800万元的终点站占地3万5290平方公尺，面积比新加坡廉价终点站大四倍，有30个停机坪、12个登机口，最多可每年接待一千万人次旅客。



廉价航空终站的经营费与吉隆坡国际机场一样，只是机场税差别马币10元而已。吉隆坡廉价航空终站两周后启用时，只有亚洲航空及亚航的子公司，泰国亚航与印尼亚航使用。

斥资4500万新元的新加坡廉价航空终站占地二万五千平方米，计每年可以迎接至少270万名乘客。廉价航空终站启用时，乘客将能使用樟宜机场的另两个主要航空终站，其中包括免费使用互联网，还有免税购物，也安排了免费巴士载送乘客往返终站。



航空业者使用廉价终站，比起在第一和第二搭客大厦，节省高达50%的费用。乘客所付的13元机场与保安税，也比第一和第二搭客大厦所征收的21元来得便宜。



服务品质有待改进

廉价航空的市场精确打击传统航空的市场。单是亚洲航空公司每年就能达到500万人次搭客量，廉价航空市场确实不能低估。有些航空公司的票价非常惊人，经常只有大公司票价的一半，甚至更低；比如：虎行从新加坡至曼谷的双程机票不含税只有新币12.20元（约马币28元）。不过，廉价航空的竞争力及其与主流航空公司的差异化服务值得探讨。

廉价航空只提供基本服务，由于票价低廉，乘客在其他方面需有些牺牲，例如虎行和亚航基本上实行采用单一机形、无固定座位。由于多数廉价航班不能预定座位，因此，在廉价航空登机处不难看见乘客为霸占走廊或较好座位，争先恐后的狼狈模样。此外，由于不允许乘客携带食品，飞机上所有服务都得付费，食物和饮料要另外收费，快熟售价大约马币六元左右。

“享受”比经济舱还糟的乘坐环境，廉价航空登记行李重量的上限也一度引起争议。一般廉价航空只允许乘客登记15公斤行李，超重得缴付额外行李费；手提行李不得超过七公斤。一般航空的寄舱行李最多为20公斤，超重的行李则需支付每公斤3-15美元（约马币10-57元）不等的运费。

此外，廉价航空的购票程序也不见得利“客”。多数廉价航空都需通过网络系统购票，在机场代理处购票得支付额外服务费。虎行推行网上订购优惠（Internet Discount Fair），从新加坡飞往广州的机票，网上订购价为新币69.98元（约马币161元），门市价则是新币79.98元（约马币184元）。



而且，不是所有廉价航空都采用银联卡支付方式，例如亚航在海外的网上购票程序均采用信用卡支付。廉价航空主打市场是背包旅游者、出国留学生或中阶层收入者，不是每人都有信用卡，尤其是在籍学生。

廉价航空的票价波动幅度令人措手不及。春秋航空六月份推出特价机票一度轰动中国国内市场，主打航程如上海至珠海不含税仅人民币299元（约马币142元）、上海至青岛不含税仅人民币199元（约马币94元），在三天内售完。其余票价均随时间段波动，如上海至珠海的不含税票价在6月20日早晨查询为人民币399元，当天傍晚却升至人民币660元，而在6月21日中午却挂人民币560元出售。虽然廉价航空都实行“越早订机票能享受越廉宜的票价”，但是价格不稳定的确令乘客感到莫名其妙，不能明确预算出游的成本。

廉价航空均采用小飞机开拓支线，如春秋航空的统一机型空中巴士A320飞机。这是为了节约初期成本及更有效控制客流量并提高客座率。部分廉价航空如惠旅航空把客机维修、地勤服务和餐饮，甚至公司财务部门工作外包给承包商，专心一致地确保航班的准时起降，提供消费者高素质的服务。



惠旅的准时起降率达99%，居冠同业者。截至今年七月，亚航准时起降率仅达81%，仍有待改进。须知廉价航空在价格上的让步等同与乘客“睡眠时间的让步”；比方说亚航从澳门飞往吉隆坡价格较优惠的航班定在凌晨二时三刻，飞机狭挤的客座无法让乘客舒适地休息，导致许多乘客彻夜未眠。

No sign of life where Brazilian jet crashed
By Cesar Bianconi

BRASILIA, Brazil (Reuters) - Military searchers parachuted down on Saturday to the wreckage of a Brazilian passenger plane that crashed a day earlier in remote Amazon jungle with 155 people on board.

President Luiz Inacio Lula da Silva said there was no sign of survivors.


If the death toll is confirmed, it will be the worst aviation accident in Brazil's history.

Brazil's military suspended the search and rescue mission as dusk set in the thick forested area and will resume it Sunday morning.

"At night in the Amazon you can't see beyond a foot in front of you," said Brigadier Antonio Gomes Leite Filho of Brazil's air force at a news conference.

Earlier in the day, the two soldiers who rappelled from a helicopter into the area were cutting down dense jungle to make a helicopter landing area and authorities had recruited Indian trackers to find a path to the remote jungle crash site for relief teams. Previously, a statement by authorities implied that the soldiers had parachuted into the area.

"All rational logic shows there is a high probability that a collision occurred," Infraero head Brigadier Jose Carlos Pereira told reporters.

The small size of the wreckage area indicated that the chances of survivors among the 149 passengers and six crew members on board were slim.

Gol officials said there were 113 men and 42 women on board, including an 11-month-old boy and four children. The airline said there were only about half a dozen foreigners on the flight, though the company didn't disclose their nationalities.

"Imagine the velocity at which it hit the ground coming from an altitude of 36,000 feet (11,000 meters)," Pereira told reporters. "It's very unlikely that there will be survivors."

Authorities lost radar contact with Gol flight 1907 on Friday afternoon during its journey from the principal Amazon city of Manaus to the capital Brasilia, the airline said.

Search planes found the crash site in Mato Grosso state, about 1,000 km northwest of Brasilia.

DISTRAUGHT FAMILIES

Friends and relatives, many wearing dark sunglasses and hugging and crying, gathered on the patio of a hotel in Brasilia waiting for details. Most could not utter more than one word before bursting into tears.

"Gol ... would not say if there might be any survivors," Robson Barreto said as he waited for news on his 29-year-old nephew Rafael who was a passenger.

Denise Abreu, director of civil aviation authority ANAC, said signs indicated there had been a mid-air collision with a smaller jet, which landed safely.

Embraer aircraft manufacturer said one of its executive jets, a Legacy 600 owned and operated by a client, had been involved in a collision and made an emergency landing at Cachimbo air force base with five passengers on board. No injuries were reported.

The Gol plane had been received new from Boeing on Sept. 12 and had only 234 flight hours, the company said.

Until now, the worst air disaster in Brazilian history was the June 1982 crash of a Vasp flight which hit a mountain near Fortaleza in northeastern Brazil, killing 137 people.

PARIS (AP): Airbus chief executive Christian Streiff resigned after a little more than three months as head of the troubled European plane maker, and parent company EADS named one of its own co-CEOs to replace him.

European Aeronautic Defence and Space Co. said in a statement Monday that Louis Gallois will succeed Streiff in the top job at Airbus while continuing in his current role as joint head of the Franco-German defense group.

Streiff's departure deals a fresh blow to crisis-hit Airbus. The plane maker, which stunned investors in June by doubling the A380 superjumbo's production delay to one year, doubled it again this month to two years and said the holdups would wipe a total of euro4.8 billion (US$6.1 billion) off EADS profits over four years.

Streiff took over as Airbus CEO just over three months ago, replacing Gustav Humbert, who was ousted along with EADS co-CEO Noel Forgeard as a result of the A380 production crisis.

The 52-year-old former Saint-Gobain executive drew up a cost-cutting turnaround plan for Airbus that enjoyed strong support from EADS directors, but he clashed repeatedly with the board over how the plan should be implemented and how much control he would personally exercise, according to three officials familiar with the discussions.

Streiff wanted to report to the parent company every quarter and have final say on Airbus appointments, while senior EADS executives demanded closer oversight, according to the officials, who asked not to be named because the discussions were confidential.

In an interview for Tuesday's edition of the French daily Le Figaro, Streiff said he had not been allowed the "necessary operational powers'' to do the job effectively and welcomed as "a step in the right direction'' the combination of the Airbus and EADS roles for Gallois.

Since the creation of EADS in 2000, Airbus managers have answered to a separate chief executive at the parent company as well as their own. The A380 production delays, which came to management's attention only belatedly, have been blamed in part on the blurred reporting lines between EADS and its civil jet unit.

Those lines should be clearer as a result of the changes announced Monday. EADS' German co-CEO Tom Enders will no longer have direct managerial responsibility for Airbus, the statement said -- leaving Gallois as sole boss. EADS owns 80 percent of Airbus and is tightening up supervision of the civil jet unit as it acquires the remaining 20 percent from Britain's BAE Systems PLC.

"If my successor doesn't have enough elbow room, and if the governance of Airbus doesn't evolve, then yes, the company's future is worrying,'' Streiff warned.

Streiff upset the delicate political balance underpinning EADS and unnerved German politicians and trade unions by suggesting that work on the A380 could be transferred to France from Germany and the A350 XWB -- a planned rival to Boeing's 787 -- could also be built in France.

The German government has suggested it may take a stake in EADS if carmaker DaimlerChrysler AG pares its own 22.5 percent holding. "We must prevent everything from going the way of the French,'' German Defense Minister Franz Josef Jung was quoted as saying Monday by weekly Der Spiegel.

After concentrating massive resources on the superjumbo, Airbus was taken by surprise by Boeing's two-engine 787, which delivers better fuel economy than older four-engined Airbus jets in the same size category -- a sales argument that has grown more persuasive with higher fuel prices.

The gap is widening fast. Airbus took orders for 226 jets through Sept. 30, the Toulouse, France-based aircraft maker said Monday, compared with the 723 net orders announced by Boeing for the year to Oct. 3.

Earlier Monday, Gallois met with French Prime Minister Dominique de Villepin and Finance Minister Thierry Breton, and a spokesman for President Jacques Chirac said the head of state was following the situation closely. Restructuring at Airbus is on the agenda for Thursday's Franco-German summit, when Chirac and Chancellor Angela Merkel are to meet in Paris.

Shares in European Aeronautic Defence and Space Co. closed 1.3 percent lower at euro20.16 (US$25.41) in Paris ahead of the announcement.

太阳观测卫星于星期三由三角洲二号火箭发射

STEREO Solar Observatories Launching Aboard Delta II on Oct. 25

Launch of NASA's STEREO spacecraft is scheduled for Wednesday, Oct. 25, aboard a Boeing Delta II rocket from Pad 17-B at Cape Canaveral Air Force Station, Fla. The launch window is 8:38 to 8:53 p.m. EDT. Should the launch be postponed for 24 hours for any reason, the launch window is 8:26 to 8:41 p.m. EDT, or for a 48-hour postponement, 8:32 to 8:47 p.m. EDT.

STEREO consists of two spacecraft that together comprise the first mission to take measurements of the sun and solar wind in 3-D. This new view will improve our understanding of space weather and its impact on the Earth.

During the two-year mission, the nearly identical spacecraft will explore the origin, evolution and interplanetary consequences of coronal mass ejections, the most violent explosions in our solar system. When directed at Earth, these billion-ton eruptions can disrupt satellites, radio communications and power systems. In addition, energetic particles associated with these solar eruptions are hazardous to scientific spacecraft and astronauts.

Truly an international effort, many portions of the STEREO instruments were provided by the United States, the United Kingdom and several European countries. The Johns Hopkins University Applied Physics Laboratory, in Laurel, Md., designed and built the spacecraft and will operate the twin observatories for NASA during the mission. NASA's Goddard Space Flight Center in Greenbelt, Md., is responsible for the project management. The NASA Launch Services Program at Kennedy Space Center and Boeing Expendable Launch Systems are responsible for the launch.

有意收购Airod 莎当再也要取得控制权 2006/10/28 18:01:19
●南洋商报

（吉隆坡28日讯）据消息表示，莎当再也（Satang，7212，次板贸服股）有意收购国内宇航业的翘楚Airod有限公司控制权。

市场观察员表示，假设上述消息落实的话，除了为莎当再也现有的业务带来辅助效益之外，也有助于扩大莎当再也的企业版图。

莎当再也主要为军事、航空及海事器材的供应商，而Airod 有限公司主要为国家军事及商用飞行公司提供航空维修服务。该家公司为大马政府在1985年国内企业私营化程序中，首家进行企业化的政府机构

在政府宣布大肆进行企业私营化之后，数家由政府控制的机构都先后上市，包括国家能源（Tenaga，5347，主板贸服股）、马电讯(TM，4863，主板贸服股)，惟Airod有限公司仍保持私人有限公司地位。

莎当再也于上周五飙涨24.6%或28仙，以1.34令吉闭市。

在截至今年6月30日的财政年度内，该公司取得1千230万令吉，比前期所取得的450万净利增长3倍。

（吉隆坡訊）除了逮捕兩名嫌犯查辦，警方也正追查另數人的下落，以協助調查“800名男女應征空姐空少險遭騙財騙色”的案件。

八打靈再也警區主任哈占助理總監証實警方已於上週四（6日），在靈市格拉那再也地區逮捕兩名嫌犯，包括一名自稱古瑪機長的男子調查。


他說，這兩名嫌犯將被延長扣留至本週三（11月1日）。此外，警方目前正追查另數人的下落，以協助調查這起案件。

哈占針對有人非議警方延誤採取逮捕行動而表示，警方需收集更的資料和文件，才展開進一步的行動。

他解釋，在一些商業罪案中，涉案者也沒有被扣留，直至被控上法庭。

馬華公共服務及投訴部主任拿督張天賜及本地唯一的航空培訓及就職中心Inter-excel8公司負責人張嘉芳週日（29日）非議警方延誤採取逮捕行動。

此外，由於嫌犯指他們是受新加坡代理允准進行這項招募活動，因此相信警方將尋求新加坡警方的協助，以查是否屬實。 （星洲日報‧2006/10/30）

Pilot project to stimulate minds of young children


PUTRAJAYA: A pilot project to enhance young children’s skills and mental development will be launched next year with a RM20mil government allocation.

Deputy Prime Minister Datuk Seri Najib Tun Razak said the Cabinet approved the concept, billed the Early Childhood Education and Care (ECEC), that stimulates the creativity, imagination and interests of children up to six years old.

“The concept has proven successful in several countries; and the children there were also found to be more emotionally mature,” he told reporters yesterday after chairing a meeting with mentris besar and chief ministers.

“We will set up the centres in all states and different environment, such as rural areas, estates, towns and cities with children from different socio-economic backgrounds to test the programme’s effectiveness.”

Najib said a committee chaired by him would implement the programme, and the panel members would include prominent women such as Universiti Kebangsaan Malaysia vice chancellor Prof Datuk Dr Sharifah Hapsah Syed Hasan Shahabudin and Universiti Malaya vice-chancellor Datuk Rafiah Salim.

“The idea to introduce the ECEC came from my wife (Datin Seri Rosmah Mansor) who had discussed the matter at length with a group which expressed their concern over current social problems,” he added.

On another matter, Najib said he had relayed Prime Minister Datuk Seri Abdullah Ahmad Badawi’s reminder to all state governments to give full cooperation towards the implementation of projects.

“The Federal Government has asked the state governments to provide appropriate land in terms of quality and location so that additional expenditure need not be incurred,” he added.

The Deputy Prime Minister also said that telecommunications companies must widen their coverage and not just concentrate on places with high usage.

“We want the Energy, Water and Communications Ministry to direct telcos to improve their services and increase their coverage to make mobile phone network service available throughout the country,” he said, adding that there were still blind spots in rural areas and Felda.

"Silent Aircraft" Designed By Scientists

AP) A U.S.-British team of researchers from academia and the aerospace industry believes the passenger aircraft of the distant future will not only be fuel-efficient, but virtually silent.

Leaders of a long-range research venture called the "Silent Aircraft Initiative" were scheduled Monday to release a conceptual design for a plane they say could cut through the air with practically no sound bothering those below, thanks to its unique shape and design features to limit engine noise.

The design adds a new twist to aviation's long history of mixed success developing flying wings designed to be more fuel- and space-efficient than conventional aircraft with long, narrow fuselages.

The design, to be announced in a news conference at the Royal Aeronautical Society in London, would blend fuselage and wings together so that the entire airframe provides lift - an approach that to date has been confined largely to payload-carrying military aircraft such as long-range bombers.

The body shape of the "silent aircraft" would allow for a slower landing approach and takeoff to cut airport noise - a form of environmental pollution that makes it politically unpopular to expand airports and flight schedules.

"The 'silent aircraft' can help address this concern and thus aid in meeting the increasing passenger demand for air transport," said Edward Greitzer, and professor of aeronautics at the Massachusetts Institute of Technology.

Even if he's right, don't expect to see - or hear - such a plane anytime soon. The project is aimed at establishing research knowledge that could lead to development of an aircraft by 2030. And whether such a plane could become a commercial success is anybody's guess.

But the project, led by researchers at Cambridge, Mass.-based MIT and Cambridge University in England, has plenty of commercial interest so far. The two universities say more than 30 aviation companies from around the world participated in the design, including aircraft maker Boeing Co. and engine maker Rolls-Royce PLC.

Rolls-Royce wouldn't participate if the project didn't have potential to help shape future aircraft design, said Martin Brodie, a spokesman for the London-based company.

"We have a very strong record of involvement in environmental programs anyway, so this is just a logical thing for us to get involved in," Brodie said. "This is really a clear-blue-sky thing for the moment, and we'll have to wait to see what develops."

More than 40 researchers from MIT and Cambridge as well as engineers from the 30 companies have been collaborating on the design since the project's launch three years ago. Funding has come largely from the British government's Department of Trade and Industry, which committed money seven years ago to establish the Cambridge-MIT Institute, a joint venture between the schools that also has worked on other projects.

For now, the aviation project's goal is not to produce a marketable aircraft.

"The goal was to find out what technologies would be required, and what an aircraft would look like if a step-change in noise reduction was one of the key drivers for design," said Zoltan Spakovszky, an MIT aeronautics professor and a chief engineer on the project.

One aspect of the plane's sound-reducing design eliminates flaps - hinged sections on the rear of each wing - to reduce a major source of noise as the plane cuts through the air at takeoff and landing.

To reduce sound reaching the ground, the jet engines would be embedded into the plane's body, rather than hung from the wings as on conventional airliners. The engines would have variable-size jet nozzles, allowing slower jet propulsion during takeoff and landing but efficient cruising at higher speeds.

The proposed plane is designed to carry 215 passengers and achieve fuel efficiency of 124 passenger-miles per gallon.

By comparison, Boeing's 787 Dreamliner, a fuel-efficient airliner due for delivery in 2008, is expected to achieve 100 passenger-miles per gallon on a typical flight, Boeing spokesman Adam Morgan said.

The Cassini spacecraft is roughly halfway through its looping voyage of the Saturn system and is continuing to return a bounty of data on the ringed planet and its moons. Yet all journeys must have an end and Cassini's eventual fate is now being discussed.

"Current planning is for a two year mission extension that ends on July 1, 2010," said Robert Mitchell, NASA's Cassini mission program manager. "However, presuming that the spacecraft continues to function well, it's reasonable to expect that one or more further extensions will be supported."

Sometime around 2012, Cassini, like the ocean-going ships of old, will need to be decommissioned. However, the spacecraft cannot be towed to some nearby shore to be dismantled; she must either drop anchor, be scuttled, or cast off her gravitational moorings altogether.

"Perhaps the most likely option is to leave Cassini in a long-lived orbit that would have little to no risk of ever hitting anything," Mitchell said. "Another is to impact Saturn like Galileo did at Jupiter, although there are some complications with this one."

The complications arise from the beautiful wafer-thin rings that girdle the planet and the fact that in order to dive into Saturn, Cassini would have to pass through them—a risky maneuver that could render the spacecraft uncontrollable.

Crash landing?

"Another option is to identify one of Saturn's icy moons as an acceptable candidate and impact the spacecraft onto it," Mitchell said.

Yet this option also holds an inherent risk arising from the three plutonium bearing Radioisotope Thermoelectric Generators (RTGs) Cassini uses as a power source.

"The issue is the heat that would be generated by the RTGs and the environment that would be created (melted ice) that could be conducive to the viability of any Earth organisms that might have survived on the spacecraft to that point," says Mitchell.

Mission planners make great effort not to contaminate alien worlds with terrestrial life.

The third option: raise anchor and escape the Saturn system altogether. Such a maneuver would require numerous flybys of Saturn's largest moon Titan to sling the spacecraft free of the ringed planet's environs.

If Cassini were to be cut adrift in this manner, her controllers have two further choices: either bring her sunward or let her escape deeper into the outer solar system.

Many options

Should Cassini be directed back toward the inner solar system it is likely her final port of call would be Jupiter, Mitchell explained, "One possibility is to escape Saturn and then most likely put the spacecraft on an impacting trajectory with Jupiter. This appears to be feasible, but the flight times get to be rather long."

Cassini's leisurely final journey need not end at Jupiter; rather the giant planet's gravity could fling Cassini into position for an impact on Mercury. Such an impact would provide valuable data on the composition of Mercury's surface and could feasibly occur around 2021 to be observed by the BepiColombo spacecraft.

Alternatively, if Cassini were cast into the solar system's outer depths there is a small chance she may provide further scientific reward in the form of a flyby of an outer planet or Kuiper Belt object.

"Some very preliminary analysis indicates that this might be possible. However, the flight times involved and the status of spacecraft consumables at that time make anything like this quite an unlikely option," says Mitchell.

NASA is to make the final decision on Cassini's eventual fate later in the mission.
