Ja, sorry dat t weer over Mars gaat Maar di's wel belangrijk nieuws!
OMEGA image of the southern polar cap of Mars 18 January 23 January 2004 ESA PR 06-2004. Mars Express, ESA’s first mission to Mars, will reach its final orbit on 28 January. It has already been producing stunning results since its first instrument was switched on, on 5 January. The significance of the first data was emphasised by the scientists at a European press conference today at ESA’s Space Operations Centre, Darmstadt, Germany. OMEGA observation of the South polar cap "I did not expect to be able to gather together - just one month after the Mars Orbit Insertion of 25 December – so many happy scientists eager to present their first results", said Professor David Southwood, ESA Director of Science. One of the main targets of the Mars Express mission is to discover the presence of water in one of its chemical states. Through the initial mapping of the South polar cap on 18 January, OMEGA, the combined camera and infrared spectrometer, has already revealed the presence of water ice and carbon dioxide ice. PFS shows different CO distribution in northern and southern hemisphere This information was confirmed by the PFS, a new high-resolution spectrometer of unprecedented accuracy. The first PFS data also show that the carbon oxide distribution is different in the northern and southern hemispheres of Mars. The MaRS instrument, a sophisticated radio transmitter and receiver, emitted a first signal successfully on 21 January that was received on Earth through a 70- metre antenna in Australia after it was reflected and scattered from the surface of Mars. This new measurement technique allows the detection of the chemical composition of the Mars atmosphere, ionosphere and surface. ASPERA, a plasma and energetic neutral atoms analyser, is aiming to answer the fundamental question of whether the solar wind erosion led to the present lack of water on Mars. The preliminary results show a difference in the characteristics between the impact of the solar wind area and the measurement made in the tail of Mars. Another exciting experiment was run by the SPICAM instrument (an ultraviolet and infrared spectrometer) during the first star occultation ever made at Mars. It has simultaneously measured the distribution of the ozone and water vapour, which has never been done before, revealing that there is more water vapour where there is less ozone. Reull Vallis - HRSC image 15 January 2004 ESA also presented astonishing pictures produced with the High Resolution Stereo Camera (HRSC). They represent the outcome of 1.87 million km2 of Martian surface coverage, and about 100 gigabytes of processed data. This camera was also able to make the longest swath (up to 4000 km) and largest area in combination with high resolution ever taken in the exploration of the Solar System. This made it possible to create an impressive picture 24 metres long by 1.3 metres high, which was carried through the conference room at the end of the press event by a group of 10-year-old children. Mrs Edelgard Bulmahn, German Minister for Research and Education, who is also chair of the ESA Council at Ministerial level, said at the press conference: "Europe can be proud of this mission: Mars Express is an enormous success for the European Space Programme."

Hier een Nederlands berichtje:
Water en ijs ontdekt op Mars Uitgegeven: 23 januari 2004 12:22 Laatst gewijzigd: 23 januari 2004 12:38 AMSTERDAM - Onderzoekers van de Europese ruimtevaartdienst ESA hebben sporen van water en ijs ontdekt op de planeet Mars. Ze hebben dat vrijdag bekendgemaakt. Instrumenten aan boord van de ruimtesonde Mars Express hebben in de atmosfeer van de rode planeet waterdamp gemeten. Bovendien is in de zuidelijke poolkap van de planeet ijs ontdekt. De zoektocht naar water en ijs was een van de belangrijkste taken van de Mars Express. http://nu.nl/news.jsp?n=264688&c=20

Nasa herstelt contact met Spirit... January 23, 2004 Mars Exploration Rover Updated Mission Status The flight team for NASA's Spirit received data from the rover in a communication session that began at 13:26 Universal Time (5:26 a.m. PST) and lasted 20 minutes at a data rate of 120 bits per second. "The spacecraft sent limted data in a proper response to a ground command, and we're planning for commanding further communication sessions later today," said Mars Exploration Rover Project Manager Pete Theisinger at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The flight team at JPL had sent a command to Spirit at 13:02 Universal Time (5:02 PST) via the NASA Deep Space Network antenna complex near Madrid, Spain, telling Spirit to begin transmitting. Meanwhile, the other Mars Exploration Rover, Opportunity is on course to land halfway around Mars from Spirit, in a region called Meridiani Planum, on Jan. 25 (Universal Time and EST; Jan. 24 at 9:05 p.m. PST). JPL, a division of the California Institute of Technology, Pasadena, manages the Mars Exploration Rover project for NASA's Office of Space Science, Washington, D.C. Additional information about the project is available from JPL at http://marsrovers.jpl.nasa.gov and from Cornell University, Ithaca, N.Y., at http://athena.cornell.edu .

Wat een vage planeet is Mars toch!
Moet je de raw images van de Opportunity eens zien. Hier in hoge resolutie (maar volgens mij "veel te rood afgebeeld") een grote kleurenfoto Hier nog een paar vage van ESA: (wat is die vage zwarte vlek? Vuiltje op de lens? ) Wat is dat groen/blauwige?

Anyway; volgens ene van het Atoomagentschap in Der Spiegel ligt een nucleaire oorlog dichterbij dan ooit. En dat zonder Koude Oorlog. Dus.
