Beagle 2: a proposed exobiology lander for ESA's 2003 Mars Express mission.

The aim of the proposed Beagle 2 small lander for ESA's 2003 Mars Express mission is to search for organic material on and below the surface of Mars and to study the inorganic chemistry and mineralogy of the landing site. The lander will have a total mass of 60kg including entry, descent, and landing system. Experiments will be deployed on the surface using a robotic arm. It will use a mechanical mole and grinder to obtain samples from below the surface, under rocks, and inside rocks. Sample analysis by a mass spectrometer will include isotopic analysis. An optical microscope, an X-ray spectrometer and a Mossbauer spectrometer will conduct in-situ rock studies.     

Sputnik fever — again?

The author offers some comments on the drawbacks of another US-Soviet space race. She compares the relative positions of the USA and the USSR in various areas of space science and technology, and concludes that the USSR does not lead in all areas. More importantly, she argues that it is distressing still to be portraying the superpowers as in a race in space. ‘Sputnik fever’ the first time round showed that a space race does not lead to a strong, long-term US space programme. She argues that cooperation in some areas — perhaps a trip to Mars — could b an alternative.     

徐华胜燃烧室技术专家

请您首先谈一谈先进航空发动机燃烧室技术的发展趋势,特别是民用航空发动机,重点要解决燃烧室什么问题? 徐华胜：燃烧室的功能是将燃料的化学能高效转化为热能,供涡轮膨胀做功,喷气发动机从诞生时采用的单管燃烧室,历经几十年的发展,到目前的高温升、高热熔短环形燃烧室,燃烧室的工作压力和温度大幅度提升.
