zhar2, bizarre is apt - this may have to move to the Martian Chronicles.
K. Well we can try doing some AGW "science" - if that doesn't satisfy you - we can go a round or two, but it seems unfair picking on an old drunk actor.
Vincent, you seem well versed in meteorology and you obviously like music. To be here you must have a fascination with Mars. Perhaps you'd like to tell us something about yourself?
Now we are getting OT
Keeping the Shuttle flying past 2010 will cost billions a year and add to the significant risk of losing another crew. That money would be far better spent accelerating Ares/Orion and if there's a some left over starting more COTS projects.
A 50 MT Shuttle C is too small and too expensive for Lunar or Mars cargo missions, and a human rated version will be too risky and wasteful. Changing the main engine to a RS-68 makes it closer to Ares V, so why not just build Ares V and get all the advantages of synergy with Ares I and the enormous extra capability? This has all been looked at for years and years, it would be nuts to start over yet again. Ares is a good solution, let's get it fully funded and press on!
Imaged 3 May 2008
At NASA's Kennedy Space Center, access arms from the fixed service structure at Launch Pad 39A are extended toward space shuttle Discovery, secured atop the mobile launch platform below, as final prelaunch processing for the STS-124 mission gets under way at the pad.

It does seem a bit odd to me. The way it looks to me is that by then it will be night time at the lander site, but I guess I'm missing something big there
Does Canberra have the honor of receiving EDL or the first image data?
EDL goes through Goldstone. Canberra comes into line of sight (of the relaying spacecrafts) just after landing and will hopefully carry the first image.
Maybe it's the additive delay of the next relay pass plus the time it takes the relay to see the DSN again, because Mars will have rotated about 30°
What's the first signal Canberra should see?

Dust Devils at Phoenix Landing Site (MRO/Context cam) - imaged 20 Apr 2008
NASA's Phoenix Mars Lander is scheduled to land on the Martian northern plains near 68 degrees north latitude, 127 degrees west longitude on May 25, 2008. In preparation for the landing, NASA's Mars Reconnaissance Orbiter has been monitoring weather in the region around the landing site. On April 20, 2008, the orbiter's Context Camera captured this view showing two active dust devils within the Phoenix landing ellipse.
This is a subframe covering an area about 26 kilometers (16 miles) on each side, part of a larger image posted at PIA10632. It shows two dust devils and their shadows. Based on measurement of the shadows cast by the dust devils, one of the vortices towered about 590 meters (about 1,930 feet) with a dust plume extending 920 meters (about 3,020 feet) above the surface. The other reached about 390 meters (1,280 feet) high, with a dust plume extending to 790 meters (2,590 feet). The resolution here is 6 meters (19.7 feet) per pixel.
When the Context Camera acquired this image, the season in Mars' northern hemisphere was late spring. A few weeks earlier, the Phoenix landing site was still covered with seasonal frost left over from the previous winter. White patches in small craters near the center of the picture are areas where the winter frost remained, even as late as April 20.
As spring gives way to summer, dust devils are likely to occur more frequently, as local temperatures rise. These two dust devils observed in late April are among the first of the season. The cameras on the Phoenix lander might be able to spot additional dust devils after the spacecraft arrives, as the Mars Exploration Rover Spirit has been able to do at its southern hemisphere landing site.
Dust devils are whirling vortices that have picked up dust from the ground. Such vortices can occur even when no dust is present, but then they are not visible to the cameras onboard the Mars Reconnaissance Orbiter. Such vortices commonly form as hot air rises from the surface on an otherwise generally calm day with little or no breeze. Dust devils will travel across the surface on the gentle breezes that do occur. Sometimes, dust devils have been observed by cameras orbiting Mars to create streaks on the ground as they disrupt and pick up dust, though no streaks are observed in this image.
Landing Area Viewed by Mars Color Imager - 6 May 2008
NASA's Phoenix Mars Lander is scheduled to land on the Martian northern plains near 68 degrees north latitude, 127 degrees west longitude on May 25, 2008. In preparation for the landing, NASA's Mars Reconnaissance Orbiter has been monitoring weather in the region around the landing site. On April 20, 2008, the orbiter's Mars Color Imager camera captured this view of a large region of northern Mars that includes the landing target area in the lower right quadrant.
An annotated version of the image indicates the location of the landing ellipse, about 100 kilometers (60 miles) long. The Context Camera on the Mars Reconnaissance Orbiter took an image of the landing area at the same time the Mars Color Imager took this image. A dot within the landing ellipse marks the location of two active dust devils visible in the Context Camera image, PIA10633. When the Mars Color Imager acquired this image, the season in Mars' northern hemisphere was late spring. A few weeks earlier, the Phoenix landing site was still covered with seasonal frost left over from the previous winter.

Thanks. ERT would be very helpful.
MEX has near polar elliptical orbit (10107x298 km) with a period of 6.7 hours
MRO has an almost circular 250x316 kms polar orbit with a 2 hour period
ODY is in a science/relay polar orbit around 400kms also with a period of 2 hours
2:40 hours plus after landing! - then we'll need oxygen tanks .
Does Canberra have the honor of receiving EDL or the first image data?
All spacecraft configurations - currently in "Cruise" mode (see photo)
From: Mission Design Overview (PDF 7MB) - 29 Jun 2007
Are those simulation times Earth receive time?
Communication will probably be lost during peak heating, so that will cause a shortage of breath.
It seems that there will be UHF contact with MRO/ODY/MEX during EDL. If it's like the MER system, a sequence of tones will signal each step in the landing sequence (chute deploy, heat shield jettison etc etc) waiting for the whole sequence will take about 4 mins after parachute deployment until we know she's on the surface. Plenty of time to go blue even without the extra 2 mins.
Then we have to wait for the next orbiter pass to learn about the initial deployments (solar arrays etc etc), that's when we all pass out :>
Hybrid expandable mini-hab and outpost configuration
From Structural Definition and Mass Estimation of Lunar Surface Habitats (PDF 11MB) - dated 14 Mar 2008
A hybrid hard-shell/mid-expandable concept was also developed and evaluated. The complete outpost using hybrids would consist of 3 mid-expandable Habitats for a total volume of 189 m3 <snip> The mid-expandables are landed on the lunar surface as pre-integrated unpressurized units that, once emplaced, are subsequently expanded and outfitted.
<snip>
Because the Mini-Habs were to be off-loaded from the Lander and placed on the lunar surface, an external cargo handling truss <snip> was integrated to the exterior of the module. This truss had several functions, including; integrating the module with the Lander, transferring launch loads from the Mini-Hab into the Lander, serving as the cargo handling structure on the lunar surface, and serving as the structure to which the ground support legs and leveling system would be attached. Exterior systems, such as solar arrays and radiator panels, or panels that could support regolith and provide long-term protection from galactic cosmic radiation, could also be added.
These mini habitats could be landed together with crew.
Dawn Journal update - 22 Apr 2008
Dawn continues its powered flight, having accumulated more than 100 days of ion thrusting since its launch nearly 7 months ago. All systems are healthy as the probe patiently and persistently propels itself through the solar system.
In addition to its weekly hiatus in thrusting to point its main antenna to Earth for about 6 hours, Dawn's flight plan includes occasional longer intervals to conduct special activities. On March 31, the spacecraft stopped its ion beam, turned to Earth, reported on its activities from the previous week, and indicated its readiness (even eagerness!) for whatever plans mission control had devised. This period, scheduled well before launch, was planned to last 10 days.
To begin, the team loaded into the spacecraft's main computer updated software that simplifies operation of the science instruments. Such "science blocks" had already been used in the mission, but with the experience gained from the tests of the instruments in the initial checkout phase, the team made some improvements. After thorough testing with instrument simulators, the modified science blocks had been deemed ready for installation on the spacecraft. They were used during the rest of the week, as each of Dawn's science instruments received special attention.

River delta in Nepenthes Mensae (MEX/HRSC) - imaged 22 Jan 2008
The data was acquired in the region lying at approximately 3° north and 121° east with a ground resolution of 15 m/pixel.
The southern part of the image shows a structure reminiscent of a river delta on Earth whose material was eroded from a valley, about 30 km long and upto 1000 m deep. This formed a fan-shaped deposit at the mouth of the valley. The rim of the deposit stands roughly 300 m above the floor of the depression.
The resemblance of the structure to river deltas on Earth suggests that it was formed by a similar mechanism. Scientists believe that sediment transported by water was deposited as the flow of the water slowed down where the channel widened and met the mouth of the river.

NASA Videographer Blog - 4 May 2008
Tomorrow morning at 5AM the folks at ATK Launch Services will begin pouring the first of 47 large vats of the propellant...and that's only for 1 of the 5 Ares I stages.
NASA Videographer makes the Ares Quarterly Reports, the next one should be released this week - all the reports can be viewed here as youtube videos.
Yes, welcome dmuller!
And thank you for setting up such a useful page, seeing the mission events unfold as PHX cruises towards Mars is fascinating.
30 secs or even two minutes won't make a big difference for us
(we get a huge number of spammers, and of course the first thing they want to do is post a link - you ought to be able to post links now)
Shows the main mission timeline events before landing and other data such as: Altitude above Mars, Speed relative to Mars and Distance to Landing. Note that arrival time on Mars is 30 seconds slower than the mission page.
Next mission event, Trajectory correction maneuver 4: in just 5 days
Just a guess: because the VAB only has two bays that can hold Shuttles. As soon as a Shuttle is ready, it's moved to the pad to make space for the next one in the flow. Weeks of checkout and payload installation work are done on the pad.
It didn't need to invade a country...
We can discuss that in Free Chat.
Human space flight should be non military just as commercial aviation.
When a new fighter aircraft is developed nobody expects pilots to die because of design or production mistakes, and quite rightly so. Accidents happen of course, but good design and procedures minimize them. Combat is unsafe but the best designed aircraft flown by the best trained pilots are not expected to have many losses. Compared with DoD, NASA is cheap and quick. Examples:
F-22 program:
development: $62 billion
time from requirements to introduction: 24 years
F-35:
development: $40 billion
time from requirements to introduction: 18 years (expected 2011)
And these are nth generation fighter projects unlike NASA human spacecraft which have only had a few generations.
Just because it won't happen doesn't mean that it's impossible
Don't forget that $10m Ansari gave to the X Prize, the $20m that Paul Allen put up to develop SpaceShip One and the recent $30m that Google offered. There's a factor of six on the $10m of donations. Why is that important? Because it doesn't need millions of donors, just a few can make a big difference.
(if there's no objection this topic will move to space politics)
