Ahaha, jos jedna rasprava o tome koja je planeta najlepsa...pa jeste da su saturn i neptun lepi kad se gledaju iz svemira, ali mars ima najvece a i najlepse geoloske(tj. areoloske;)) formacije u suncevom sistemu.

Dobro je da se josh ne raspraljaju koji im je omiljena klisura Meni Sicevachka.

[iguana]

ma jupiter rula, malo je jebena klima i vetrovi , ali kada se naviknesh mnogo kul mest. meni je barem lepo tamo

shalu na stranu, ipak je velichina i tekstura jupitera nesto najfascinantnije, posebno velika crvena mrlja, olujni sistem koji postoji vec stotinama godinama ako ne i vishe.

btw da li je neko od vas chuo za faeton ? ne, ne, folksvagen

[Dule_smor]

To je kao planeta cijim je raspadom nastao asteroidni pojas izmedju marsa i jupitera?Fina pricica:).

[KalElen_]

zemlja je josh uvek najlepsha, ali koliko dugo

moja omiljena klisura je "crocodile gorge":J

help save the wild life:J odakle mi je beshe ovo poznato?

shta bi na kraju sa ovim ?

[Attila]

ma bre javite kada pronadju vanzemljace

[Therion]

ma meni se najvishe svidja ona kockica leda na kraju, kako se ono zvashe... pluton!

heh, voleo bih da sam se ulenjio ili da me je "gospodja uzela pod svoje", ali tuzna istina je da imam previshe posla...

dodushe nadam se da ce i to skoro proci

A nekada misije prosto ne uspeju, jer neko zaboravi da "stisne dugme" :))

SPOKANE, Wash. - David Atkinson spent 18 years designing an experiment for the unmanned space mission to Saturn. Now some pieces of it are lost in space. Someone forgot to turn on the instrument Atkinson needed to measure the winds on Saturn's largest moon.

"The story is actually fairly gruesome," the University of Idaho scientist said in an e-mail from Germany, the headquarters of the European Space Agency. "It was human error — the command to turn the instrument on was forgotten."

The mission to study Saturn and its moons was launched in 1997 from Cape Canaveral, Fla., a joint effort by NASA (news - web sites), the European agency and the Italian space agency. Last Friday, Huygens, the European space probe sent to the surface of Saturn's moon Titan, transmitted the first detailed pictures of the frozen surface.

Atkinson and his team were at European space headquarters in Darmstadt, Germany, waiting for their wind measurements to arrive.

The probe was to transmit data on two channels, A and B, Atkinson said. His Doppler wind experiment was to use Channel A, a very stable frequency.

But the order to activate the receiver, or oscillator, for Channel A was never sent, so the entire mission operated through Channel B, which is less stable, Atkinson said.

"I (and the rest of my team) waited and waited and waited," he wrote, as the probe descended. "We watched the probe enter and start transmitting data, but our instrument never turned on."

Officials for the European Space Agency said last week they would investigate to learn what happened. They were not available for comment on Thursday, nor did NASA officials immediately respond to telephone messages.

Atkinson wrote in his e-mail that fellow scientists rushed to comfort him and his team.

Most of his team has returned home, but Atkinson has remained in Germany because he still has a task to perform — reconstructing the entry and descent trajectory of the probe.

There is hope that some of his data survived.

"We do have Channel B data and although driven by a very poor and unstable oscillator, we may be able to get a little bit of data," he wrote.

Also, he said some of the Channel A signal reached Earth and was picked up by radio telescopes. "We now have some of this data and lots of work to do to try to catch up," he wrote.

Even so, he said the overall space mission was a huge success, and the Europeans in particular were thrilled with the success of their Huygens probe.

"In total, the core of our team has invested something like 80 man years on this experiment, 18 of which are mine," Atkinson wrote. "I think right now the key lesson is this — if you're looking for a job with instant and guaranteed success, this isn't it."

Pa da, to je ono o cemu sam pricao, debili su zaboravili da ukljuce drugi kanal tako da pola slika nije ni stiglo.Ali dobro je, bolje to nego da se sonda slupa zato sto neko nije pretvorio stope u metre:).

I ovo je odlicno :))

Titan a 'Flammable' Moon Covered in Liquid Gas

LOS ANGELES (Reuters) - Saturn's moon Titan is covered by "dirty" ice ridges and seas of liquid natural gas, a team of scientists said on Friday after a week of research into data from the space probe Huygens.

"We've got a flammable world," said Toby Owen, an atmospheric scientist, at a news conference from European Space Agency offices in Paris monitored on NASA TV.

After a seven-year piggyback trip from Earth on board the Saturn probe Cassini, the European-designed Huygens separated in December and fell toward Titan, entering the moon's atmosphere last Friday.

The probe, part of a $3 billion joint mission involving NASA and the European and Italian space agencies, sent back readings on the moon's atmosphere, composition and landscape.

Slowed by parachutes, Huygens took more than two hours to float to the icy surface, where it defied expectations of a quick death and continued to transmit for hours.

That surface, which scientists have said was the consistency of wet sand or even creme brulee, features ice rocks, channels, and abundant indications of liquid from rain.

"There's lots of evidence of fluid flow," said Marty Tomasko, the principal investigator for Huygens' on-board imaging instruments. While it does not rain every day on Titan, Tomasko and colleagues speculated there must be some sort of regular precipitation on the surface.

The methane can exist in liquid form on Titan's surface because it is so cold, -290 degrees Fahrenheit (-179 degrees Celsius). Methane is also a key component in Titan's atmosphere, along with nitrogen. But as opposed to the Earth, the atmosphere of Titan lacks oxygen, which is essential to fire.

"There's no source of oxygen available, which is a good thing or Titan would have exploded a long time ago," Owen said.
