To some people, the Moon can seem like a rather boring place – gray, dusty and covered in craters. It is also usually thought to be bone dry, not the first place that comes to mind when you hear about water elsewhere in the Solar System, and for the most part that may be true, but now new evidenceshows that the Moon may be a lot wetter in its interior than previously known.
Sending human astronauts to Mars is a dream shared by many, but there are still challenges to overcome and the question of just how to accomplish it is a subject of intense debate. Some supporters advocate sending a mission directly to Mars, while others think that returning to the Moon first, for potentially beneficial training, is the way to go. Indeed, former astronaut James Lovell, who flew on two trips to the Moon, has also called for a return to the Moon first. NASA itself has stated its desire to send a crewed mission to a nearby asteroid first, instead of the Moon, going a bit farther into space than the Moon as its idea of preparation for the much longer journey to Mars. A major problem has been that NASA has still not set a firm timetable for such a mission; it wants to go to Mars, but the steps to achieving that goal are still unclear.
Exactly two years from today, on Aug. 21, 2017, a rare total solar eclipse will be seen again in the skies of the United States, racing east from Oregon to South Carolina. For a brief couple of minutes, the skies will darken as the Moon passes in front of the Sun, revealing the Sun’s corona, which is not normally visible in daylight, to millions of people as it crosses coast to coast for the first time in nearly a century. A total solar eclipse is one of the greatest sights in nature, not to be missed, and many are already making plans to witness the event.
