NOTE: Today's video is about 4:30 long. If you want to watch and listen to more of Mr. Larson, we have a second "bonus" (Flash) video for you. Or you can read the transcript, which covers both videos.
Other findings released today include preliminary indications that Pluto's atmospheric pressure has dropped sharply from early observations. This may indicate that the atmosphere is in the process of freezing and falling to Pluto's surface. Finally, new close-up pictures of the surface transmitted back to Earth show direct evidence of nitrogen ice floes reminiscent of glacier movement on Earth. The dwarf planet also seems to be rich in methane ice and carbon dioxide ice.
To the uninitiated, a scrabble game played by top players looks like they had played in Martian. Here's a taste: In a single game in last year's Nationals, Richards played the following words: zarf (a metal holder for a coffee cup), waddy (to strike with a thick club), hulloed (to hallo, to shout), sajous (a capuchin, a monkey), qi (the vital force in Chinese thought), flyboats (a small, fast boat), trigo (wheat) and threaper (one that threaps, disputes). Richards has a photographic memory and is known for his uncanny gift for constructing impossible words by stringing his letters through tiles already on the board. "He is probably the best Scrabble player in the world at this point," says John D. Williams, Jr.. "He's got the entire dictionary memorized. He's pretty much a Scrabble machine, if such a thing exists." So, really, how does he do it? As Richards said in an interview posted on YouTube, "I'm not sure there is a secret. It's just a matter of learning the words." All 178,691 of them.
The fossil fuels we're burning are old — so old they don't contain any C-14. The more we burn these fossil fuels, the more non-C-14 carbon we pump into the atmosphere. If emissions continue as they have for the past few decades, then by year 2050 a shirt made in that year (2050) will have the same C-14 signature as a shirt worn by William the Conqueror a thousand years earlier.
One possible explanation being discussed at DLR's Lander Control Center is that the position of Philae may have shifted slightly, perhaps by changing its orientation with respect to the surface in its current location. The lander is likely situated on uneven terrain, and even a slight change in its position – perhaps triggered by gas emission from the comet – could mean that its antenna position has also now changed with respect to its surroundings. This could have a knock-on effect as to the best position Rosetta needs to be in to establish a connection with the lander.
The current status of Philae remains uncertain and is a topic of on-going discussion and analysis. But in the meantime, further commands are being prepared and tested to allow Philae to re-commence operations. The lander team wants to try to activate a command block that is still stored in Philae's computer and which was already successfully performed after the lander's unplanned flight across to the surface to its final location. "Although the mission will now focus its scientific priority on the orbiter, Rosetta will continue attempting – up to and past perihelion – to obtain Philae science packets once a stable link has been acquired," adds Patrick Martin, Rosetta mission manager.
