Today's 2 topics:

- The NASA, New Horizons spacecraft woke up from its 18th sleeping period in the last 9 years. Its long space naps have lasted an average 104 days each.

- One candidate with the shortest round trip mission time of 186 days, is 2014 TW. It was discovered by my Catalina Sky Survey teammate, Jess Johnson. This asteroid is about 70 feet in diameter and orbits the Sun every 381 days.
