the Death Penalty ???

no thanks

I know folks in China are very keen on this, and many leaders, senator and governors in the USA are queit happy with this from of punishment.

Death by Injection, kill them by firing squad, Fry them in old sparky, I know Idaho & Oklahoma & Utah and others were keen on filling them with bullet holes, kill them by gas chamber technique is also there...This kind of stuff goes on in the USA, China and other places but will it be any good for Mars ?

First of all we may offend many liberals, socialist or green investors, corporations and firms and liberal individuals who may be willing to support Martian settlements whith their big Euros, Yen, Pounds, Dollars whatever. The Public will alos get very unhappy if innocents are put into old sparky by mistake.

Secondly its a waste of human flesh, manpower and resources, I say work 'em as a Punishment. Have them digging holes, grinding up rocks, until they snuff it. Kind of like a Penal Colony or a Soviet Siberian Labour Camp, and don't say those places don't punish folk enough....because they were tough places to be according to written articles

JIMO was to be NASA's first nuclear-powered mission

but its launch date has already slipped from 2011 to 2015

http://www.nature.com/news/2005/050124/ … 3342a.html

Jupiter Icy Moons Orbiter, a high-priority mission to look for saltwater oceans, and perhaps life, beneath the ice that covers the Jovian moons Europa, Ganymede and Callisto.
Delayed once by NASA's decision to power it with a nuclear reactor being developed to power manned bases on the moon and Mars - it has been slowed again by a decision to move the reactor experiment to an earlier mission.
Overall, NASA's 2006 budget estimate shows steady growth through 2010 for space science programs related to robotic and human exploration of the solar system. But the money for astrophysics, for studies of the solar environment and climate change are flat.
"There has been a concrete and very specific decision that the top priority is solar system exploration and that anything that doesn't contribute to that gets lower priorities," says John Logsdon, a space historian at George Washington University.
Some liken what is emerging from the Bush administration to the centrally planned economies that ultimately fail to raise a nation's standard of living.

Cut Project Prometheus / JIMO
they are to include no funding for the Jupiter Icy Moons Orbiter (JIMO) mission in its FY2006 budget proposal, effectively killing the program ?

several viewers have noted some strange effects
-Up or down, in or out?
...Look at these two images. They are both the same, except one appears to have 'raised' features rather than craters. This is a common illusion, and can be explained by the fact that we humans have been used to light sources which generally come from above (the Sun mostly in our case).

When you turn this pattern upside down (or rotate by 180 degrees), your eyes suddenly see a crater as a 'mountain' and vice versa.

Titan's surface and atmospheric features are shown here in this processed visible light image taken by Cassini.
Cassini's visible light spectral filter is sensitive to a broad range of light, from ultraviolet to near-infrared. Imaging scientists normally use a narrow-band filter centered at 938 nanometers to look at Titan's surface and cloud features

Science from Mars Express after one year in orbit

16 February 2005
ESA PR 10-2005. After reaching its observational orbit around Mars a year ago, ESA’s Mars Express has already delivered an avalanche of scientific data of unprecedented quality that have completely changed the way in which we think about the Red Planet.
In order to compare views and discuss the implications of the new discoveries, over two hundred scientists will be attending the first Mars Express science conference, taking place from 21 to 25 February

Period of Long Eclipses Ending
15 Feb 2005 14:50
Overall Mission and Payload Status
The Mars Express payload operations continue to run smoothly, with scientific instruments operating normally and the spacecraft in good condition. The period of long eclipses, from January to February 2005, is ending without any power or thermal problem to date.

Observed DISR Spectra on Titan
http://sci.esa.int/science-e-media/img/ … screen.jpg
Quote:
During the Huygens descent to the surface of Titan the DISR instrument recorded visible and infrared spectra (the change in the amount of light with varying colour or wavelength) of the ambient sunlight which is absorbed, diffused, and reflected by both the surface and the atmosphere. The figure shows spectra obtained by the Downward Looking Infrared Spectrometer at three altitudes: 150 km, 500 m and 20 m above the surface.

Saturn's complex rings are both an intriguing scientific puzzle and a supreme natural wonder. This view shows, from upper right to lower left, the thin C ring, multi-toned B ring, the dark Cassini Division, the A ring and narrow F ring.
At bottom, Mimas (398 kilometers, 247 miles across) orbits about 45,000 kilometers (28,000 miles) beyond the bright core of the F ring. The little moon is heavily cratered and is thought to be largely composed of water ice. The bright speck just outside of (below) the F ring is the shepherd moon Pandora (84 kilometers, 52 miles across).

-YLR - Thanks for the link to the flash animation, at the end it says that in December 2015 Rosetta's journey will come to an end. However as it'll still be attached to the comet it's journey will be ongoing - we'll just miss it all! Amazing how many fly-bys its going to have though.

SMART-1 Mission Extension Approved
15 Feb 2005

Quote:
The SMART-1 extension of 1 year will provide opportunities:

To extend the global coverage compared to the nominal 6 months mission, where good illumination conditions for IR spectrometry, X-ray sensitivity and quantitative colour radiometry will be encountered only for 25% of the time
To make use of the new orbit (3000 km apolune instead of original 10 000 km) to map both southern and northern hemispheres at high resolution, and not only the southern hemisphere
The new orbit is also more stable and requires less fuel for maintenance
The extension increases the probability of solar flares events (especially in rising solar activity) for very sensitive D-CIXS scans providing high resolution maps of Fe and rare elements in addition to Mg, Si, Al
The extension gives the possibility to perform detailed studies of areas of interest by performing stereo measurements for deriving topography, multi-angle observations for studying the photometric function and therefore the local regolith texture
An extension allows to perform dedicated programmes to prepare future international lunar missions (seasonal illumination maps at high resolution, mapping potential landing sites for future missions, including the South Pole Aitken Sample Return)

There has been much of the discusion on replacing hubble under http://www.newmars.com/forums/viewtopic … 1996]Topic: Hubble mistake, Action needed
http://www.newmars.com/forums/viewtopic … 2191]Topic: James Webb Space Telescope, Not a Hubble replacement but to the next

http://www.newmars.com/forums/viewtopic … 3148]Topic: $300M to destroy hubble
And these are just a few of the areas that you will enconter the discusion with regards to sending up a new telescope, the fall of the old one and under the science technology you will find out that there are many planned, currently being built and other reasons for why not to even send up a new telescope not to mention why repair the old one.
Half the hardware to build a new one is already built and the only real way to use it would be to fly a shuttle mission in the timeframe that Hubble has left before battery and gyro fails continue until the telescope is crippled and not worth further investment.
In fact it may all ready be to late....

http://www.felixonline.co.uk/2002-04/ar … p?aid=2251

these guys also think James Webb Space Telescope (JWST) will be the space-bound successor to Hubble,
not 2 launch until 2011

Poor Russians, could never get it right with Mars. Although they did have some missions that made it good but nothing ever lived too long with their Mars projects

I think they are planning some more missions in the future, the Phobos-Grunt sample return mission, and a possible Mars sample return mission by Roscosmos

Ariane ECB 12,000 kg
Delta IV heavy 12,757 kg
Did they reduce the estimated payload for the Delta IV recently? I thought it used to be 13,130 kg, but now Boeing's site says it is 12,757 kg, and Astronautix says that it is only 10,843 kg.

I'm not usre what happened to Delta-4 Heavy but I recall reading some time back on places like spaceref and spacedotcom about some problems it was having. The older Delta left a satellite in lopsided orbit, second stage engine failed to relight. One recent launch had a big underspeed, a premature engine shutdown and they were still trying to find the faults in Jan 2005, the Delta IV heavy dummy satellite didn't get going right.

I wouldn't worry about it too much because both Lockheed Martin's Atlas launcher and the Boeing Delta rocket have been fantastic rockets in the past. No nation can compare to the number of flights, deep space probes, and craft launched by NASA.

However there is now a focus on the return of shuttle, and this could be a future problem as the shuttle can face dangers when it goes on difficult missions. Right now China is trying to push ahead their space program they have a freindship with Russia, the Chinese are doing a joint Double-Star mission with ESA and they have a good relationship with USA. Chinese however have been far behind in Space and may need some years or decade to catch up. The Europeans may also be trying to push forward their designs and develop better rockets for the future, a lot of times Europe does joint training with its Astronauts in Russia and they do co-operative projects with the US and NASA has lauched ESA missions to Space. Today the ESA may perhaps be looking to launch all their own projects next, become more independant. The are maybe doing improvemenst on their rockets and have done various launches for XXM, Hipparcos, Envisat, Giotto, Smart-1 and so forth, so perhaps as Europe looks more to the Moon and Mars they may improve the Ariane again. As GCNR said in the ' HLLV essay ' thread, the old Energia-Bruan is buried, and the factory roof has collapsed, and ESA doesn't have the goal of manned missions yet plus an Ariane-M type design would take billions of dollars / euros to build. However ESA does have many future missions planned and do have a goal for other explorations they have more money than Russia and surely been looking into launchers for these.Yet Russia is of course doing other stuff, the Russian with their Soyuz may soon be launching from the ESA laucnh pad in South America. As far as I can tell the Russians have been doing agreements with Kouru in French Guiana and the Arianespace and this will allow the Russians to launch more and leave more Space for Space Tourism. Russians also plan to launch the Klipper or Clipper it reminds me of the old Soviet plan for a Buran and Polus during the time of the USSR Empire. Russia will show their Kliper at the air show in French Le Bourget, as for its launch method I'm not sure the Russians already have their Soyuz, I don't think they'll have it lifted by a Angara but with all the wording from Russian news sources it seem the Energia rocket may return someday soon.

NASA has been the king of Space, it won the Space race against the Soviets. Its rockets have been fantatsic and they have done incredible missions, but other nations are growing fast. Can NASA afford another mishap or a large failure like what happened with shuttle, this would be very bad. That's why I think it's important that it all goes well in these next months ahead. I know that NASA has been considering launching astronauts in a Crew Exploration Vehicle aboard either the Boeing Delta 4 or Lockheed Martin Atlas 5. The shuttle return is going to be very important, but it is not without big risks.

NASA is ahead now, and it has some of the best rocket designs but if another mistake were to happen then its likely that other nations are going to catch up fast.

*Just released from ESA. Melas, Candor and Ophir Chasmas. Images taken during orbits 334 - 360. Covers an area 300 x 600 km.
It remains unclear how this gigantic geological feature, unparalleled in the Solar System, was formed. Tensions in the upper crust of Mars possibly led to cracking of the highlands. Subsequently, blocks of the crust slid down between these tectonic fractures.
In contrast, some gigantic ‘hills’ (indeed, between 1000 and 2000 metres high) located on the floors of the valleys have a smoother topography and a more sinuous outline. So far, scientists have no definitive explanation for why these different landforms exist.
Below the northern scarp, there are several landslides, where material was transported over a distance of up to 70 kilometres.

it could be the one

follow up observations carried out with NASA's Hubble Space Telescope are providing important supporting evidence for the existence of a candidate planetary companion to a relatively bright young brown dwarf star located 225 light-years away in the southern constellation Hydra.
Astronomers at the European Southern Observatory's Very Large Telescope (VLT) in Chile detected the planet candidate in April 2004 with infrared observations using adaptive optics to sharpen their view. The VLT astronomers spotted a faint companion object to the brown dwarf star 2MASSWJ 1207334-393254 (aka 2M1207). The object is a candidate planet because it is only one-seven-hundredth the brightness of the brown dwarf (at the longer-than-Hubble wavelengths observed with the VLT) and glimmers at barely 1800 degrees Fahrenheit, which is cooler than a light bulb filament.
Because an extrasolar planet has never been directly imaged before, this remarkable observation required Hubble's unique abilities to do follow-up observations to test and validate if it is indeed a planet. Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) camera conducted complementary observations taken at shorter infrared wavelength observations unobtainable from the ground. This wavelength coverage is important because it is needed to characterize the object's physical nature.
Very high precision measurements of the relative position between the dwarf and companion were obtained with NICMOS in August 2004. The Hubble images were compared to the earlier VLT observations to try and see if the two objects are really gravitationally bound and hence move across the sky together. Despite the four months between the VLT and NICMOS observations, astronomers say they can almost rule out the probability that the suspected planet is really a background object, because there was no noticeable change in its position relative to the dwarf.
If the two objects are indeed gravitationally bound together they are at least 5 billion miles apart, about 30 percent farther apart than Pluto is from the Sun. Given the mass of 2M1207, inferred from its spectrum, the companion object would take a sluggish 2,500 years to complete one orbit.

year 2006 looks better, but there also have been some things that got axed, there were small cuts in the project for CEV design and JIMO looks like it's gone

Overall they say NASA done ok, a rise but less than the expected rate, it could have done much worse with the costs of medicare, price of war in Iraq...some agency will have seen much worse and Congress could have been more harsh

On one hand you have Catholics, Irish-Republicans, Ireland-Nationalists, then extreme groups like IRA and the Real-IRA ( a small break away group that continues violence )

The on the other hand you have Loyalist-English, Northern-Unionists, English-protestants and terrorist groups like the UDA, LVF and UFF ( where violence continues ).

Today they don't fight as much and it isn't about religion and more about power and politics

Bill Clinton played a big role in the peace process and getting both sides to come together under some form of government. The Clinton admin and others from Ireland and England helped to get Northern Ireland's divided community to sit down together, it works out about 48% Irish republican 52% English loyalist. Tensions pop up every while and things start looked bad but it mostly works out somehow

The North seems to have a long and bitter history, but they are well educated and have a lot of brains unlike those Idiot crackpots in the Middle East that just want to continue blowing up things and destroying their own country, but then again has the middle east been given enough attention and enough help ?

*Could we please keep this thread focused on Saturn, Saturn's moons and Titan/Huygens?
I understand a bit of overlap and swerve might be unavoidable, but it looks like discussions might now go truly off-topic.
For other planets and old missions pertaining to them (which is off-topic for this thread) -- use "Search" and continue in an old thread established for them or create a new one and continue there please.
Thanks.
