2015 Planetary Exploration Crossword Puzzle
July 19, 2015

News services have been busy lately reporting on the most recent feat of America's national space agency's resounding success with its interplanetary space probe's closest encounter with our solar system's most remote [minor] planet. Prior to the flyby, even the most powerful Earth- and space-based telescopes could never resolve more than a few lightly contrasted splotches on the celestial orb's surface, and its largest moon was a few pixels worth of indeterminate light. All that changed on July 14, 2015. We now have, for the first time ever, high resolution images of the surface, and are in the process of collection terabits worth of additional physical data from onboard instruments. No doubt many Ph.D.'s will be earned through assimilation and study of this information.

I will be glad to create a special edition crossword for your newspaper, newsletter, etc.

About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
