ESA - Venus Express updates
« on: 04/13/2006 08:48 pm »
ESA's Venus Express has returned the first-ever images of the hothouse planet's south pole from a distance of 206 452 kilometres, showing surprisingly clear structures and unexpected detail. The images were taken 12 April during the spacecraft's initial capture orbit after successful arrival on 11 April 2006.

One year at Venus, and going strong


One year has passed since 11 April 2005,  when Venus Express, Europe's first mission to Venus and the only spacecraft now in orbit around the planet, reached its destination. Since then, this advanced probe, born to explore one of the most mysterious planetary bodies in the Solar System, has been revealing planetary details never caught before.

An exciting new series of videos from ESA?s Venus Express has been capturing atmospheric details of day and night areas simultaneously, at different altitudes.

Really fascinating stuff watching the polar vortex animations, things only seen for the first time. (and also wondering the why and how, and for how many millions or billions of years it has been going on)

RELEASE: 07-161

SPACECRAFT TANDEM PROVIDE NEW VIEWS OF VENUS

WASHINGTON - NASA's Mercury Surface, Space Environment, Geochemistry,
and Ranging spacecraft, known as Messenger, and the European Space
Agency's Venus Express recently provided the most detailed
multi-point images of the Venusian atmosphere ever seen.

The images result from a June 5 flyby of Venus by Messenger during its
long journey to Mercury. Venus Express already was in orbit at the
planet. The two spacecraft carry sets of instruments employing
different observation techniques that complement each other.

Messenger made its closest approach to Venus at a distance of
approximately 210 miles on the night side of the planet. At the same
time, Venus Express was behind the horizon, almost above the planet's
South Pole, at approximately 21,750 miles.

Scientists from both missions are continuing analysis of the images
and accompanying data. Data included several instruments studying
Venus' cloud deck and surface, plasma environment, magnetic fields,
and atmosphere. More results from this joint observation campaign are
expected by the end of the year.

Messenger launched on Aug. 3, 2004, and swung by Venus first on Oct
24, 2006, and for the second time in June. Messenger will enter
Mercury's orbit in March 2011. Venus Express, the European Space
Agency's first mission to Venus, launched on Nov. 9, 2005, and
reached the planet on April 11, 2006.

Venus Express has now orbited Earth's twin for 500 Earth days, completing as many orbits. While the satellite maintains steady and excellent performance, the planet continues to surprise and amaze us.

That approach frames ani gif they have reminds me of the approach one of the Mariner craft made to Mars, that I've seen a gif of.

New isotope molecule may add to Venusí greenhouse effect

10 October 2007

Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus.
 
The discovery is being announced today at the annual meeting of the American Astronomical Societyís Division of Planetary Sciences in Orlando, Florida. Its presence could affect the way the greenhouse mechanism works on Venus.
The mystery began back in April 2006, soon after ESAís Venus Express arrived at the second planet in the Solar System.

Press Release
No.33-07, Paris, 20 November 2007


ESA to present the latest Venus Express results to the media

How has our knowledge of Venus evolved since ESA's Venus Express spacecraft has been observing Earth's twin? To answer this question and to present fresh new results concerning our cryptic neighbour, the European Space Agency is inviting the media to attend a press conference to be held at ESA Headquarters in Paris on 28 November.

The launch of Venus Express back in November 2005 represented a major milestone in the exploration of Venus - a planet unvisited by any dedicated spacecraft since the early 1990s.

One of the fundamental questions being addressed by the Venus Express mission is why a world so similar to Earth in mass and size has evolved so differently, to become the noxious and inhospitable planet it is today.

Since it started its scientific observations in July 2006, Venus Express has been making the most detailed study of the planet's thick and complex atmosphere to date.  

The latest findings not only highlight the features that make Venus unique in the solar system but also provide fresh clues as to how the planet is - despite everything - a more Earth-like planetary neighbour than one could have imagined.  

The results will appear in a special section of the 29 November issue of the journal Nature containing nine individual papers devoted to Venus Express science activities.

Media organisations interested in attending the press conference are invited to register via the form attached below. Media that cannot attend will have the opportunity to follow the press conference via the following phone line: +33 1 58 99 57 42 (listening-mode only).

ESA's Venus Express has revealed Venus as never before. For the first time, scientists are able to investigate from the top of its atmosphere, down nearly to the surface. They have shown it to be a planet of surprises that may once have been more Earth-like, and still is, to a certain extent.

The link Jacques has provided above leads to another page in which all the latest results of Venus Express are analyzed more thoroughly. Really interesting that they've found heavy water in the upper atmosphere, and the simulation of the interactions between the solar wind and Venus' atmosphere is amazing.

I'm still reading through it, but I like the way it's presented :) Amazing days we are living, undoubtedly.

The light and dark of Venus
 
20 February 2008   Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly. Such 'global weather', unlike anything on Earth, has given scientists a new mystery to solve.

The puzzling 'eye of a hurricane' on Venus
 
13 March 2008
Venus Express has constantly been observing the south pole of Venus and has found it to be surprisingly fickle. An enormous structure with a central part that looks like the eye of a hurricane, morphs and changes shape within a matter of days, leaving scientists puzzled.

Venus Express reboots the search for active volcanoes on Venus
 
4 April 2008
ESA's Venus Express has measured a highly variable quantity of the volcanic gas sulphur dioxide in the atmosphere of Venus. Scientists must now decide whether this is evidence for active volcanoes on Venus, or linked to a hitherto unknown mechanism affecting the upper atmosphere.

15 May 2008
Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venusís dense atmosphere.

Scientists using ESA's Venus Express are trying to observe whether Earth is habitable. Silly, you might think, when we know that Earth is richly stocked with life. In fact, far from being a pointless exercise, Venus Express is paving the way for an exciting new era in astronomy.

A pale yellow dot to the human eye, Earth's twin planet comes to life in the ultraviolet and the infrared. New images taken by instruments on board ESA's Venus Express provide insight into the turbulent atmosphere of our neighbouring planet.
