Although the nascent space tourism industry still has some big questions to answer, including transport and lodgings, one of the details has been safely resolved: you can now get a pizza delivered to orbit.

"Wherever there is life, there will be Pizza Hut pizza," the Dallas-based pizza chain's chief marketing officer Randy Gier said in a statement. "If space tourism is going to be a reality, Pizza Hut pizza will make the trip even better."

Station captain Yuri Usachev salutes the first chain pizza out of the gravity well.

Despite the unusual delivery address, the pizza, called "the culmination of nearly a year of collaboration" between the company and Russian nutritionists, largely conformed to the familiar recipe served up by some 12,000 Pizza Hut restaurants worldwide -- crust, tomato sauce and cheese.

However, the vacuum-sealed space pizza was topped with salami rather than the traditional pepperoni. "Researchers found that pepperoni did not withstand the 60-day testing process," a company release rather cryptically stated.

After delivery, the station crew baked the 6-inch ("personal pan") pizza themselves in the ISS oven.

Pizza Hut, a division of Tricon Global Restaurants, pioneered the commercialization of space in July by paying to have its logo placed on a Russian Proton rocket.
