Researchers will study the information in depth after the project ends. But Mr. Braun says they also plan to do a quick examination and share that information.
The HS3 mission also is investigating something else that researchers have yet to understand. Mr. Braun says in addition to wind speed and wind direction, the researchers want to know more about temperature in the environment. He says that is especially true of something they call the Saharan Air Layer. It is a very hot, dry, dusty air mass that comes from Africa. Scientists are debating whether Sarahan dust provides material for tropical storms – or even suppresses the development of storms.
Doesn’t Everyone Love Ice Cream?
Ice cream is a frozen treat usually eaten after a meal. It can be found around the world. In Los Angeles, California, some business owners are preparing ice cream that is similar to the desserts of other countries. Onka Dekker spoons out the sweet story for us.
At the Ice Cream Lab in Beverly hills, the frozen dessert is made to order. People watch as the ice cream makers pour a liquid ice cream base into a bowl. The an odorless smoke appears from the mixture. Tommy Ngan and his business partner Joseph Lifschutz make ice cream with liquid nitrogen. Mr. Lifschutz explains.
“It’s used as an instant freezer. It kind of touches everything in the bowl and evaporates, which is why you see the whole smoke show.”
