Astronomers have spotted a cloud of gas with three times the mass of the Earth on a near-collision course with the Milky Way\s central black hole.

Earth-size worlds found orbiting another star (bit ‘ot though)
This Spaceflight Now article discusses the Kepler Orbital Observatory’s discovery of two “smallish” worlds (within a few percentage points of Earth) orbiting a star 1000 light years away. This proves that 1) Kepler can ‘see’ worlds of this size and 2) that such worlds are not radically rare since there are two in the first few dozen discovered. However both orbit too close to their star for us one’s probably got a surface temp of ~1500 the other a relatively ‘cool’ 800. Other interesting thing is that the other planets spotted (all way to close to the star) are gas ‘pigmy giants.’
A soaring NASA rocket prompts thoughts of earthly politics a year from 2012 vote by Andrew Malcolm – Investors.com
A great reflective article, I have seen 2 launches both in Florida, one an Atlas the other a Delta, both commercial, both with hundreds of others, both indescribably moving because of the awesome symbolism as much as anything else.
Could the Jetsons be Close? This would foment radical change and growth…
I had not realized that LENR (low energy nuclear reactions) research had continued. The PPT’s are actually pretty exciting but the proof is in the repeat ability. There does appear to be some developing theory and theory based experimentation, if this work bears fruit it would be a game changer.
Picture has nothing to do with the article, just APOD ‘eye candy.’
Air Force Mini Shuttle the future Swiss army knife of space
In a testing procedure, the X-37B Orbital Test Vehicle taxis on the flightline in June 2009 at Vandenberg AFB, Calif
The Air Forces X37B autonomous mini shuttle has proven a great success. The first prototype orbiting for 9 months and then returning safely. The second unit is currently at 10+ months. Also the craft have shown that they are very maneuverable in orbit and very hard to keep track of from the ground even by pretty sophisticated observers. Now The AF is talking about an X37C that could carry six passengers. But it would still be autonomous, i.e. the passengers are passengers not pilots. To me that is probably a rather weak cover/secondary use. Most of the craft would spend most of their lives with no passengers, doing an array of important tasks. I think the AF like s the idea of a more ‘drone’ like operating profile, multi use(refuel, recovery, small launch, medium duration observation, etc) able to upgrade, lower orbit so less massive ‘optics’ for any class of objective. This would be the true space fighter, not a combat vehicle, but a platform that can do almost anything almost anywhere (in orbit) on very short notice without giving away the mission just by its shape/launch orbit.
Of course they need to lose the expensive aeroshell, it was necessary I assume to keep from having to do something even more expensive with the Boosters control laws, but it sure looks expensive, and for the six person version would get pretty bulky. Of course a 6 person crew though the same as the shuttle does not mean a shuttle scale vehicle, Shuttle was a mixed cargo freight hauler most of its size was for cargo I don’t the X37C will be much more than 2x maybe 3x the size of the diminutive 29ft X37B.

A bit overweight Goldilocks
This article discussing another good candidate for a relatively Earth like world orbiting a not to distant star.
This week astronomers have announced the existence of a planet discovered to be in human livable range of star not unlike our sun, with a size 2.4 times that of our Earth and a temperature of approximately 22 degrees celsius. This is the most recent in a line of possibilities for habitable planets in the realm of possibility as outlined by an international team of scientists in a paper by the name of “A Two-Tiered Approach to Assessing the Habitability of Exoplanets” as found at Mary Ann Libert Inc, publishing — these scientists are not the same group that’ve discovered this newest planet, but they’re sure to add the new finding to their list sooner than later. What we’ve got here is Kepler 22-b, a body that is what the Kepler space telescope team says is the closest we’ve ever gotten to discovering a planet that’s like our own – an “Earth 2.0,” if you will.
G the gravity constant, being a constant would indicate that your average 150lb person (on Earth) is going to tip the scales at 300lbs. This seems in the realm of supportable but it’ll be a chiropractor’s paradise. Also would have to wonder about atmospheric density and depth, seems like there would be all sorts of interesting knock on effects.

In, Through, and Beyond Saturn’s Rings
Image Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA
Explanation: A fourth moon is visible on the above image if you look hard enough. First — and farthest in the background — is Titan, the largest moon of Saturn and one of the larger moons in the Solar System. The dark feature across the top of this perpetually cloudy world is the north polar hood. The next most obvious moon is bright Dione, visible in the foreground, complete with craters and long ice cliffs. Jutting in from the left are several of Saturn’s expansive rings, including Saturn’s A ring featuring the dark Encke Gap. On the far right, just outside the rings, is Pandora, a moon only 80-kilometers across that helps shepherd Saturn’s F ring. The fourth moon? If you look closely in the Encke Gap you’ll find a speck that is actually Pan. Although one of Saturn’s smallest moons at 35-kilometers across, Pan is massive enough to help keep the Encke gap relatively free of ring particles.
As you’ll note in the side bar one of my favorite sites is APOD Astronomical Picture Of the Day, the above picture from Saturn is from the APOD. the single largest segment of memory on my iPad is devoted to these pictures. I understand that a human’s limited senses would not see these views but they still haunt me with their beauty and inaccesibility. Here is wonder and beauty we cannot destroy.
Have to admit I’m a mite disappointed in humanity right now…hence the mooning over moons. We have a huge amount of capability and mountains of resources at our finger tips but we seem to have lost the magic sauce of leadership. I don’t know if we (humans) are going through a phase change right now or just hitting a rough patch or perhaps we have reached Lemming Stage (too many people period and some deep programming sets us at a metaphorical run towards the nearest metaphorical cliff.) I hope it’s no LS just a rough spot in the singularity….whatever that turns out to be.
Good luck Curiosity, let’s just hope you’re no cat.

The size of a compact car, nuclear powered, autonomous guidance, what’s not to geek love? Of course it’s a full press design very low fault tolerant landing system, albeit really cool, and probably warranted to work for years…exact opposite of the last two plucky cheap little explorers we sent. So I have to hope all goes well. This is not likely to be repeated for a decade if it goes thump.
Good luck Curiosity, let’s just hope you’re no cat.
