San Francisco-based artist Craig Dorety has a series of carvings that "represent segments of the moon's surface as found in the topograhical data from JAXA's Kayuga mission."
"Painstaking attention is paid to the relationship of crater groups in the composition of each carving," Craig explains. "Areas of special interest have a natural balance of crater to sea; rough to gentle in texture."
Frycook posted this fascinating video from the Apollo era on the BoingBoing Submitterator. The basic gist: Back in the day, NASA scientists tried exposing various crops—corn, lettuce, tobacco ... you know, the essentials—to moon dust. The plants weren't grown in the dust, exactly. Instead, it was scattered in their pots or rubbed on some of their leaves. In this study, the plants that were exposed seemed to grow faster than unexposed plants.
That's pretty interesting, so I dug around a little to find out more about these studies. Turns out, growing plants in lunar soil isn't quite as promising as the video makes it sound, but it's not a ridonculous idea, either. In 2010, scientists at the University of Florida published a review of all the Apollo-era research on this subject, which amounted to exactly three published studies. From that data, we can say that the plants weren't obviously affected in any seriously negative ways by their exposure to lunar soils—which is good—but we can't really say the plants grew better their terrestrial-only cousins, either.
In the end, and as recorded in the peer-reviewed scientific literature, there were only three published primary studies of seeds, seedlings, and plants grown in contact with lunar materials. In those three cases, small amounts of lunar material were used, and the plants were relatively large. In general, the dusting of plants or the mixing of lunar fines with other support media makes plant interaction with the lunar material a small part of the plant experience. At no point were plants actually grown in lunar samples in the way that one might imagine, with the entire root structure growing through and in constant association with a lunar soil. It is no accident that the wording of most of the titles of the studies, as well as the careful discussion within the papers, refers to growth “in contact with” lunar samples—not “in” lunar samples. With only a small portion of the roots, for example, interacting with the lunar materials, it is likely that plant responses to the lunar materials were, therefore, quite attenuated due to the lack of an extensive plant/lunar soil interface. Biophysical issues, such as root penetration of dry and variously hydrated lunar sample types, were completely unaddressed. Thus, the effects of actual growth within lunar soils were simply not a part of the plant studies of the Apollo era.
On the other hand, in 2008 scientists with the European Space Agency tried growing marigolds in a medium of crushed rock—basically the much-cheaper equivalent of growing plants in moon "soil". There's no indication that the marigolds did better than those grown in real dirt, but they did grow and they did survive (even without any added fertilizer), which could be indirect evidence in support of the Moon gardeners of the future.
Boing Boing reader Cory Poole is a 33-year-old math and science teacher at University Preparatory School in Redding, CA. He sends in this beautiful video of yesterday's annular solar eclipse, and says:
This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.
The full "super Moon", scientifically known as a "perigee moon", rises over Los Angeles, California May 5, 2012. A "super Moon" lit up Saturday's night sky in a once-a-year cosmic show, overshadowing a meteor shower from remnants of Halley's Comet, the U.S. space agency NASA said. The Moon looked especially big and bright, because it reached its closest spot to Earth at the same time it was in its full phase, NASA said. Below, the full moon rises behind a mosque as birds fly in Amman.
More photos of the "super Moon" as seen around the world this weekend follow, below.
Astronauts used the boxes to collect and bring back to Earth nearly 50 pounds of moon rocks and soil ... Each of the boxes was machined from a single piece of aluminum, "seamless except for the lid opening, which had a metalized gasket that firmly sealed when closed."
The United State won the race to put a man on the Moon. But we weren't the first to land anything on the Moon. That prize went to the Soviet Union, which successfully put Luna 2 on the surface of the Moon in 1959.
Luna 23 met a similar fate. Launched on October 28, 1974, it malfunctioned halfway through its mission and ended up crashing on the surface in the Mare Crisium (the Sea of Crisis in the northwest on the Earth-facing side). The spacecraft stayed in contact with Earth after its hard landing, but it couldn’t get a sample. Mission scientists expected the spacecraft had tipped over as a result of its landing, but without a way to image the moon at a high resolution, they weren’t able to confirm, and the mystery endured.
It turns out they were indeed right. The whole spacecraft is still on the surface, its ascent engine never fired, and high resolution image from LRO’s cameras show the spacecraft lying on its side.
This data visualization of the Apollo 11 moon mission gathers social and technical data from the 1969 lunar landing in video form. The horizontal axis is an interactive timeline.
The horizontal axis is an interactive timeline. The vertical axis is divided into several sections, each corresponding to a data source. At the top, commentators are present in narratives from Digital Apollo and NASA technical debriefings. Just below are the members of ground control. The middle section is a log-scale graph stretching from Earth (~10E9 ft. away) to the Moon. Utterances from the landing CAPCOM, Duke, the command module pilot, Collins, the mission commander, Armstrong, and the lunar module pilot, Aldrin, are plotted on this graph. The graph is partially overlaid on a composite image of the lunar surface.
This photo was taken last March 19 in Cordoba, Spain. Photographer Paco Bellido captured a particularly special full moon—it appeared larger than any full moon had in 20 years. NASA explains:
Full Moons vary in size because of the oval shape of the Moon's orbit. It is an ellipse with one side (perigee) about 50,000 km closer to Earth than the other (apogee). Nearby perigee moons are about 14% bigger and 30% brighter than lesser moons that occur on the apogee side of the Moon's orbit. The full Moon of March 19th occurs less than one hour away from perigee--a near-perfect coincidence1 that happens only 18 years or so.
Some Russian scientists want to build a space colony inside a network of caves on the Moon. No, really. It's hard to tell, from the Reuters story, how much support this plan actually has from the people who hold the purse strings. — Maggie
This week marks the 40th anniversary for Apollo 15, the less famous of manned lunar missions including Apollo 11, Apollo 13 ("NASA's finest hour"), and Apollo 14 (the one where Alan Shepard played golf on the moon).
Ben Cosgrove of LIFE points us to a related gallery of classic images, and explains:
While Armstrong and Aldrin walking on the lunar surface was mind-blowing, the idea of Irwin and Scott cruising around on a 450-pound moon buggy that they'd carted a quarter-million miles from Earth -- during a basically flawless mission when Scott and Irwin spent three full days on the moon's surface -- makes XV the coolest of all the Apollo missions.
