Robotic explorer heads to Mars

Robotic explorer heads to Mars

NASA's newest robotic explorer, Maven, lifted off at Cape Canave­ral and rocketed toward Mars on Monday on a quest to unravel the mystery of the planet's radical climate change. Scientists want to know why Mars went from being warm and wet during its first billion years to cold and dry today. The early atmosphere was thick enough to hold water and possibly support microbial life. Maven — short for Mars Atmosphere and Volatile Evolution — is due at Mars next fall. It then will spend a year measuring atmospheric gases. The mission costs $671 million.

Gettysburg speech to be celebrated

Thousands of people are heading to Gettysburg, Pa., today to commemorate the 150th anniversary of President Abraham Lincoln's Gettysburg Address. He delivered the speech nearly five months after the Battle of Gettysburg left tens of thousands of men wounded, dead or missing. The Union victory was a turning point in the Civil War. Interior Secre­tary Sally Jewell and James McPherson, a Civil War scholar, are the keynote speakers.
