[BoingBoing] In 1999, Jeremy Adolphson, then 17, began sending artists that he likes 4" x 6" notecards in the mail with a stamped return envelope and a request to draw him a picture. Now, he has hundreds of amazing artworks from the likes of Dan Clowes, Hunt Emerson, Chester Brown, Seth, Chris Ware, Roberta Gregory, Will Eisner, and many more.

Now a team led by Brown University planetary geologists has produced the first uniform, comprehensive catalog of large craters on the moon that could shed light on the full-scale, planetary bombardment that characterized the inner solar system more than 4 billion years ago. In a paper appearing on the cover of Science, the team used data from the Lunar Orbiter Laser Altimeter, one of a suite of instruments aboard NASAs Lunar Reconnaissance Orbiter, to identify and map 5,185 craters that are 20 kilometers in diameter or larger. From the crater count and analysis, the team, which includes scientists from the Massachusetts Institute of Technology and the NASA Goddard Space Flight Center, determined the moons oldest regions are the southern near side and the north-central far side. The group also confirmed that the South Pole-Aitken Basin is the oldest basin, meaning that any samples from there could be invaluable to further understanding the moon and other bodies of the inner solar system. In all, the findings are telling us something about the infancy of the solar system, said James W. Head III, a planetary geologist at Brown and the papers lead author. It is clear we can find out and learn so much more from future missions, robotic or otherwise. There is so much to do. A major finding deals with the stream of projectiles pinballing throughout the inner solar system in its earliest days. For years, the prevailing wisdom was that the moon was buffeted by a volley of space matter that held a steady ratio between larger and smaller objects, which planetary scientists refer to as size-frequency distribution. The bombardment activity has never been questioned. But in 2005, the size-frequency distribution was challenged. In a paper in Science, a group led by University of Arizona geologist Robert Strom hypothesized that the ratio of larger and smaller objects striking the moon had differed during its first billion years of existence. The Brown-led teams crater analysis lends added credence to that hypothesis. The researchers studied impact craters formed early in the moons history (when major basins were created by large projectiles striking the surface) and compared them with those they knew were formed later (when objects struck lava flows that had covered these basins). They found that the oldest surfaces (located in the lunar highlands) bore crater markings indicating a greater ratio of larger projectiles. The group looked in particular at Orientale Basin, formed by a massive impactor about 3.8 billion years ago, and determined that this is approximately when the era of larger projectiles versus smaller projectiles ended. The finding opens a set of intriguing questions for what was going on in the inner solar system leading up to roughly the time that Orientale Basin was formed, said Caleb Fassett, a postdoctoral researcher at Brown and a contributing author on the paper. We know the asteroid belt has been spinning off projectiles at a relatively constant rate for three and a half billion years, he said. But now we go back earlier in the solar systems history, and suddenly things are completely different. That implies theres a different forcing to the asteroid belt. What has caused that different forcing is still not known. The scientists think the change may have been caused by the gravitational pull on the asteroid belt exerted by larger planets such as Jupiter and Saturn as they settled into their orbits, a temporary abundance of comets, an unexplained change in the size of matter emanating from the asteroid belt, or something else. The Lunar Orbiter Laser Altimeter LOLA measures the moons surface topography at a vertical precision of 10 centimeters using laser pulses bounced off the lunar surface just 25 meters apart. The topography of the moon has been measured before, but this takes it to another level with the accuracy of data points and spatial resolution, said Maria Zuber, a planetary geologist at MIT who earned her doctorate at Brown in 1986 and is a contributing author to the paper. Seth Kadish, a graduate student at Brown, contributed to the study by analyzing the craters and assessing the results. Other authors are Erwan Mazarico and David Smith from MIT and Gregory Neumann from NASA Goddard. Head, Neumann, Smith, and Zuber are members of the NASA LOLA team. NASA funded the research.

By SETH BORENSTEIN AP Science Writer © 2011 The Associated Press MON – May 16, 2011 CAPE CANAVERAL, Fla. — With wounded Rep. Gabrielle Giffords on hand to watch, the space shuttle Endeavour is poised to give the work week a roaring and historic start Monday, overcoming wiring problems that grounded it last month. NASA began fueling Endeavour late Sunday night for the second-to-last shuttle flight. Giffords’ arrival in the afternoon included a quick fly-by of Endeavour on the launch pad, then she bid husband Mark Kelly goodbye at the bucolic beach house used by shuttle crews before launch. “Gabrielle is excited for tomorrow’s launch. Do you plan to see history in the making?” her staff tweeted. Later, her staff added: “Gabrielle & Mark said goodbye during visit before launch. Beach House made for picturesque setting.” NASA officials said conditions — from weather to technical issues — couldn’t look much better for the scheduled 8:56 a.m. launch Monday. Giffords, traveling on a NASA jet with the family of pilot Gregory Johnson, arrived shortly after the protective structure that surrounds Endeavour was moved out of the way — a milestone in launch preparations that allows fueling to begin late Sunday night. NASA was so ready to get the flight off the ground that they moved the protective scaffolding 15 minutes earlier than planned. There was only a 30 percent chance of a weather delay, mostly because of crosswinds. The conditions were far different from last month’s futile launch attempt. The protective cover wasn’t removed for five hours because of storms, and the launch was scrubbed because of an electrical problem. Because of the early morning launch, Endeavour’s crew will be working odd hours, going to bed when most people are ready to eat dinner. Just before 5 p.m. Sunday, Endeavour astronaut Mike Fincke tweeted that he was going to sleep and then promised an early morning update to his more than 10,000 Twitter followers:
