2. Kepler reaction wheel still problematic after mitigation
In this computer graphic, NASA's Voyager 1 probe, moving toward upper left, nears the edge of the sun's influence, flying through a region of space dominated by a "magnetic highway" that helps mediate the flow of particles into and out of the solar system. The region includes particles from the sun's southern hemisphere that have been forced northward by the pressure of the interstellar wind. Voyager 1 is expected to cross the boundary into interstellar space sometime within the next few years if not sooner. (Credit: NASA)

5. The Night Sky Monday, April 15
• The Moon right after dark is in the top of Orion's very dim Club. That's not far from the center of the huge Winter Hexagon: Sirius, Procyon, the Pollux-and-Castor pair, Capella, Aldebaran (under Jupiter), Rigel, and back to Sirius.
Tuesday, April 16
• Look left of the Moon after dark for Procyon. High above the Moon is Pollux, with Castor at its right. Equally far below the Moon is Betelgeuse, the top corner of Orion.
Wednesday, April 17
• The Moon this evening is passing almost midway between Procyon to its lower left and Pollux to its upper right. Castor, slightly dimmer, shines to the right of Pollux.
Thursday, April 18
• The Moon is exactly first quarter at 8:31 a.m. EDT this morning, which means it looks equally "first quarter" on the evenings of the 17th and 18th from North America's eastern time zones. The Moon this evening is in dim Cancer, inside the big, long triangle of Procyon, Pollux, and Regulus.
Friday, April 19
• Look for Regulus and the Sickle of Leo to the left of the Moon this evening, as shown here.
