Another test?

Another test?

ya. calling it a second qualification test.

Yup. Infrared photo overlayed on a true color photo, or some thing like that.

The auroras were photographed by Hubble during a series of observations of Jupiter made in far ultraviolet-light. The full-color disk of Jupiter used in the image was photographed separately by Hubble at an earlier time.

To gain more data on the auroras, the Hubble Space Telescope has been staring at Jupiter for 45 minutes every day for the past month. At Earth, auroras light up when solar wind particles slam into molecules of air near the polar regions. At Jupiter, the charged particles come mostly from a different source: the volcanos of Io. Jupiter's powerful magnetic fields then accelerate the particles into the planet's atmosphere.

On Earth, auroras appear over an area about as large as the United States. Jupiter's auroras, like everything else there, are vastly larger, about as wide as five Earths.

"But we've never been able to get up close and really observe these processes," Fran Bagenal, a professor of astrophysical and planetary sciences at the University of Colorado and one of the mission scientists, said at the news conference. "So we can then compare them with what we see at Earth, what we seen at Saturn."

No idea where to put this.

During World War II, Wald applied his statistical skills when considering how to minimize bomber losses to enemy fire. Researchers from the Center for Naval Analyses had conducted a study of the damage done to aircraft that had returned from missions, and had recommended that armor be added to the areas that showed the most damage. Wald noted that the study only considered the aircraft that had survived their missions—the bombers that had been shot down were not present for the damage assessment. The holes in the returning aircraft, then, represented areas where a bomber could take damage and still return home safely. Wald proposed that the Navy instead reinforce the areas where the returning aircraft were unscathed, since those were the areas that, if hit, would cause the plane to be lost.

Kind of a fun story.

Clever people can be very clever sometimes.

Seems a bit of common sense really.

[Xevross]

Seems a bit of common sense really.

If that was true then researchers wouldn't have suggested it

[the-pi-guy]

Seems a bit of common sense really.

It is, and it isn't.  

It isn't because it just seems like going to a doctor with a broken leg and the doctor insisting that the rest of your body needs to be X-rayed.  

At the same time, it's like"why didn't I think of that?"
