Who first found that Europa's surface is ice-rich?
According to David Morrison in the introduction to the book "Satellites of Jupiter," both Americans and Russians can lay some claim to the discovery. He writes: "Near-infrared photometry provided the first clue to surface composition; in a landmark abstract Kuiper (1957) suggested from limited data, never published, that Europa and Ganymede had water ice surfaces, and Moroz (1961) later came to the same conclusion from similar broadband infrared observations."
How old is Europa's surface, and how do we know?
Galileo imaging shows that Europa's surface is sparsely cratered, meaning that the surface is probably young. Simulations of comet and asteroid orbits indicate that it is primarily comets which slam into Europa and the other Galilean satellites. From the modeled and observed numbers of comets in the vicinity of Jupiter today, estimates can be made for the surface age of Europa based on the number and sizes of the moon's impact craters.

Will I get rich?
The 48 Hour Film Project: Frequently Asked QuestionsProbably not. As far as we know, no one has made much money selling a 48HFP film. However, some of our filmmakers have had success with their films in other festivals including SXSW; one team won a $100K filmmaking package at a festival; and filmmakers have used recognition of their 48HFP film to get paying work. Additionally, we at the 48HFP have set up an arrangement whereby if we're able to earn money by distributing your film, you will receive a portion of that money.
What causes frost or ice crystals to appear on the surface of frozen vegetables such as broccoli?
National Center for Home Food Preservation | Freezing FAQsInadequate draining of vegetables before freezing, slow freezing or fluctuation of storage temperatures above 0°F may cause undesirable formation of large and excessive ice crystals. This can affect the texture as well as appearance of frozen vegetables.

WILL I BECOME RICH?
XINTENSE.COMI doubt it. Hardly any model earns more than a london PA at best. Most models learn to live the life early in their careers, the Gucci, Prada etc & this all costs. So most models have to suppliment their income with dancing in a club etc as this pays (generally) a lot more than modeling. So don't be fooled into thinking you will drive a Z4 & holliday in Marbella, unles you are a household name, and a good one at that. Find a football player. Time for Print is very simple.

Frequently Asked QuestionsIf you have some surface source which you'd like to paint to some surface destination at position (x, y) you would use code as follows: cairo_t *cr = cairo_create (destination); cairo_set_source_surface (cr, source, x, y); cairo_paint (cr); Note that the paint operation will copy the entire surface.

Do "icebergs" really exist on Europa?
In close-up pictures of Europa's "chaos" region, it can be seen that there are "blocks" or "plates" which have moved about relative to one another. These have informally been referred to as "icebergs," but this term is improperly suggestive, invoking visions of ice chunks floating in terrestrial polar seas. On Europa it would be extremely difficult, if not impossible, to melt from a subsurface ocean all the way to the surface.
When will the Europa Orbiter get there, and how will it determine whether there is an ocean?
Launch of the Europa Orbiter mission has been delayed until perhaps 2006 or 2007. Travel time to Jupiter is about 3 years, then it takes another 2.5 years or so to drop into Europa orbit. This means arrival in 2013 or 2014. The mission itself would last only a month or two after that, but enough to make critical measurements.
