Finally, a mission we can reasonably expect to watch immediate results from.
(adds to daily site check list) The ESA Venus Express mission plans to orbit the 2nd planet within 96 days. See the Venus Express Special Home Page Official Mission Science & Technology Home Page Launched November 9th on a Russian rocket watch it here Looks like ESA is working on some regular podcasts, too. That Venus... she's smoking hot, but the acid clouds and crushing pressure might make her a bit too much of a bitch for most of us to handle. |

Thank for the new threads curiousuburb. I love this kind of thing.
Also, in the 'spirit' of exploration, I'd like to wish Spirit a happy 2 year anniversary today, and Opportunity a happy number 2 coming up on the 25th. May you both avoid the sticky dunes and may the wind always be at your solar panels. So it goes. |

I agree. Burb, you are righteous in your choice of postings. Was watching a show from last January about the Mars missions. Can't believe two years have past already. Good stuff....

Venus by Ben Bova was a fun read (as are most all of Bova's books).

So, when do we get to Venus?

7 days until Venus Orbit Insertion... all systems go.
Details of the timeline of events can be found here, while a more general press release is here, including webcast schedule for live coverage And there's a new podcast up. All those who believe in telekinesis, raise my hand. |

18 hours to Venus Orbit Insertion...
Check the ESA webcast schedules if you want to watch the mission control reaction. By tomorrow, we should have groovy new images and data if all goes well. But a bit like MRO, the orbital aerobraking and adjustment will take a few months to refine to the optimum for data gathering... tomorrow may be one of our few chances to see the full disc before a lower orbit puts us too close for the big picture view. All those who believe in telekinesis, raise my hand. |

Awesome. Don't take the lack of replies here as disinterest in the subject. I'm sure there are other curious readers such as my myself who just have nothing to add.

Successful Orbit Insertion!
Earth's Evil Twin has a new orbiter. BBC Story The press conference seemed oversubscribed (and only available in WMP), but should replay later for those who want to check the ESA TV Previous Transmissions Page Space.com story Quote:

Geez, they weren't kidding when they said "highly elliptical". I'm surprised it won't burn up getting that low.
Edit: Hmm... that might not be as low as I thought it was. Anyone know how thick Venus's atmosphere is? When I was a kid, people who did wrong were punished, restricted, and forbidden. Now, when someone does wrong, all of the rest of us are punished, restricted, and forbidden... and the one who did the wrong is counselled and "understood" and fed ice cream.

I believe 155 miles is well within the atmosphere of venus as its atmosphere is considerably thicker than earths...

Earth's atmosphere is about 100 km thick...
It isn't an easy calculation but given that Venus is about the same size as earth, has an atmosphere that is composed mostly of CO2, which is approximately 1.5 times as dense as nitrogen, and that it is 90 times as massive -- I would guess that its atmosphere is anywhere between 30 and 60 times as thick as earths... |

No, fixing the air won't help... Water and methane (the products of photosynthetic fixation of CO2) are better greenhouse gases that CO2... In fact, it would get even hotter...

How do you plan on "fixing" about 4,698,585,000,000,000,000,000 tonnes of CO2 anyway, Dave?
I'm out of the loop on planetary space missions, but I was under the impression that NASA had sent a rover to Venus. How did the craft survive the descent through the dense atmosphere, and the high temperatures on the surface? Venus seems like a pretty shitty place to spend the night! |

There have been landers on Venus... mainly Russian Soviet ones, the Venera missions ( 3 through 14... not all "successful" ), but temperatures that melt lead, sulfuric acid rain, and atmospheric pressures equivalent to 1km below the sea meant that none lasted long. There are a few more images... including some from the surface on the links above. No rovers. Yet. All those who believe in telekinesis, raise my hand.

Hey, they've only planned for TWO DAYS of this mission! How shortsighted is that? |

So what do the women of Venus look like? They've got to be hot. Sorry, all this talk of insertion has me a little worked up.

Interesting, but I seriously hope the scientists extract more information out of the constant stream of blurry images from these satellites than I do. When I see the images I always wonder whether they're worth millions of pounds/dollars/euros. Although exploration for its own sake is perhaps a worthy goal.

Venus Express Update: Final Orbit of Venus Reached
The original ESA story is below (complete with some awkwardly translated stuff). Basically the orbit now ranges elliptically between 250 km and 66,000 km, allowing for a nice mix of observations. The actual science isn't set to begin until full instrument check out is finished on June 4th, 2006, although we may see some calibration images or interim data that week. Quote:

Atmospheric Double Vortex discovered at Venusian South Pole.
