"But we are not of those who shrink back and are destroyed, but of those who have faith and preserve their souls." -Hebrews 10:39

Earth -- as seen by the Juno spacecraft flying by our home planet on October 9, 2013: In this image of Earth taken by JunoCam, you can see observations made during Juno’s Earth flyby gravity assist that was completed earlier this month. Several Juno science instruments made planned observations during the approach to Earth, including the Advanced Stellar Compass, JunoCam and Waves. These observations provided a useful opportunity to test the instruments during a close planetary encounter and ensure that they work as designed. The main goal of the flyby – to give the spacecraft the boost it needed in order to reach Jupiter – was accomplished successfully.

The Juno spacecraft was launched from Kennedy Space Center on August 5, 2011 toward Jupiter. Juno’s rocket, the Atlas 551, was only capable of giving Juno enough energy or speed to reach the asteroid belt, at which point the Sun’s gravity pulled Juno back toward the inner solar system. The Earth flyby gravity assist was planned as part of Juno’s trajectory to increase the spacecraft’s speed relative to the Sun so that it is sufficient to reach Jupiter. (The spacecraft’s speed relative to Earth remains constant.) Because of the flyby, Juno’s velocity relative to the Sun increases from 78,000 miles (126,000 kilometers) per hour to 87,000 miles (140,000 kilometers) per hour. Juno is moving much faster than satellites that orbit the Earth because Juno is orbiting the Sun, not Earth.

As of Oct. 17, Juno was approximately 4.4 million miles (7.1 million kilometers) from Earth. The one-way radio signal travel time between Earth and Juno is currently about 24 seconds. Juno has now traveled 1.01 billion miles (1.63 billion kilometers, or 10.9 AU) since launch. With the Earth flyby completed, Juno is now on course for arrival at Jupiter on July 4, 2016.

"Infection control, confidentiality, and privacy are all important, but they alone cannot complete the circle of care we need. We are not just broken down mechanisms that need to be repaired. We are also suffering human beings, who need someone at our side we can talk with and get to know. Sometimes what we need more than anything else is a friend. What a shame it would be if our zeal for privacy prevented us from making a friend at the very moment in life when, perhaps more than any other, a friend is just what we need most."

"Could it be that we face so much sexual confusion in the church because we fail to preach faithfully through all of Scripture? Society shames sex by speaking of it too often in the wrong context, with smirks and innuendos. Conversely, we in the church often shame sex by failing to speak of it all, missing the opportunities the Word of God appropriates for our instruction."
