## Translations of Space Math Problems into Other Languages

Over the years, there has been an increasing interest for translations of many of the math problems at this website. Although the collection of problems is extensive ,we will try to translate some of the more popular problems into non-english languages over the next few months. We will select the problems that are frequently the most popular ones in english and translate them into the languages of the countries that most often visit this website each month. In most cases, native speakers have volunteered to help with this translation process, but we will supplement this assistance by using the GOOGLE language translation service online. Translation by using automated programs has come a long way in recent years, and we feel that GOOGLE's service is at least a good first-try at this process. If you find that some problem translations are rather poor, please let us know!

## English

What time is it? - Students work with a simple Time Zone problem involving Greenwich Mean Time (GMT) and Local Time in various countries.

Craters on the Moon - Students use a photograph of the moon's surface, and a ruler, to measure the sizes of craters on the moon, then determine the actual sizes of the craters in kilometers.

Solar Storms - Fractions and percentages - Students learn about the different kinds of solar storms by creating a simple Venn Diagram.

Scientific Notation In this exercise, students will convert some very large and very small decimal numbers into Scientific Notation form.

Unit Conversions Converting gallons to liters and many more fun conversions!

Calculating Molecular Mass The structure formula of a molecule adefovir dipivoxil is presented and students count the number of atoms it contains to determine the mass of the molecule.

The Rosetta Spacecraft Views Asteroid Lutetia The surface is seen closeup to reveal hundreds of craters. Students measure the sizes of craters.

NASA's Lunar Reconnaissance Orbiter Sees Apollo-11 Lander on the Moon The spectacular image lets students measure the sizes of craters near the Apollo-11 lander, and determine from the Lander's shadow length the elevation of the sun above the horizon.
