A Russian spacewalk on ISS today.

A Russian spacewalk on ISS today.

What is especially interesting about this spacewalk is its participants, Pavel Vinogradov and Roman Romanenko. Vinogradov at 59 years old is the oldest person to do a spacewalk. It is his seventh EVA. Roman Romanenko meanwhile is following in the footsteps of his father, Yuri Romanenko, who spent three months in space in the late 1970s on Salyut 6 followed by a ten month mission on Mir in 1987. As far as I can remember, this makes Romanenko the first second-generation astronaut in history.

Update: a reader has noted that Richard Garriott was the first second generation astronaut, beating Romanenko by one year. See the comments.

Hubble has taken a spectacular close-up image of the Horsehead Nebula.

A horsehead of another color: Hubble has taken a spectacular close-up image of the Horsehead Nebula.

Also, if you want to find out exactly how powerful Hubble is in comparison with both ground-based and other space telescopes, check out the video provided by this press release for the new images by the Herschel Space Telescope of the Horsehead Nebula that were also released today. Herschel, which works in the far-infrared, produces good data and information that Hubble cannot, but its imagery cannot compare.

Using Kepler astronomers have found a solar system with five terrestrial-type planets, with two in the habitable zone.

Eden? Using Kepler astronomers have found a solar system with five terrestrial-type planets, with two in the habitable zone.

Using observations gathered by NASA’s Kepler Mission, the team, led by William Borucki of the NASA Ames Research Center, found five planets orbiting a Sun-like star called Kepler-62. Four of these planets are so-called super-Earths, larger than our own planet, but smaller than even the smallest ice giant planet in our Solar System. These new super-Earths have radii of 1.3, 1.4, 1.6, and 1.9 times that of Earth. In addition, one of the five was a roughly Mars-sized planet, half the size of Earth. …

The two super-Earths with radii of 1.4 and 1.6 Earth radii orbit their star at distances where they receive about 41% and 120%, respectively, of the warmth from their star that the Earth receives from the Sun. The planets are thus in the star’s habitable zone; they have the right temperatures to maintain liquid water on their surfaces and are theoretically hospitable to life.

Theoretical modeling of the super-Earth planets, Kepler-62e and Kepler-62f, suggests that both could be solid, either rocky–or rocky with frozen water.

This is big news. Additional info can be found here and here.

Senator Max Baucus (D-Mont.) said Wednesday he fears a “train wreck” as the Obama administration implements Obamacare

Idiot: Senator Max Baucus (D-Mont.) said Wednesday he fears a “train wreck” as the Obama administration implements Obamacare.

Baucus was one of the key architects of Obamacare and voted for it, along with every other Democrat in Congress. That he is only now discovering what a bad law it is is just further proof that he should fired.

The real question is whether the voters will fire him. After the last election I have my doubts.

The American Communist Party has sued the Democratic Party for stealing their platform.

Heh. The American Communist Party has sued the Democratic Party for stealing their platform.

“They stole our entire platform, rebranded it ‘progressive’, and claimed it as their own,” declared a CPUSA spokesperson at a press conference in San Francisco. “And we communists say, not so fast! Not in this country anyway, where we still have property rights and the rule of law, thank God! Actually, let me rephrase that…”

A union is calling for the repeal of Obamacare.

3:18 pm

The house of cards begins to fall: A union is calling for the repeal of Obamacare.

Our Union and its members have supported President Obama and his Administration for both of his terms in office.

But regrettably, our concerns over certain provisions in the ACA have not been addressed, or in some instances, totally ignored. In the rush to achieve its passage, many of the Act’s provisions were not fully conceived, resulting in unintended consequences that are inconsistent with the promise that those who were satisfied with their employer sponsored coverage could keep it.

These provisions jeopardize our multi-employer health plans, have the potential to cause a loss of work for our members, create an unfair bidding advantage for those contractors who do not provide health coverage to their workers, and in the worst case, may cause our members and their families to lose the benefits they currently enjoy as participants in multi-employer health plans.

But don’t worry, come the next election this same union will continue to support the same Democratic politicians that gave us Obamacare, because party partisanship is far more important than common sense and rational leadership.

Because its FAA test flight permit will expire on May 23, SpaceShipTwo’s first powered flight has to occur by then and be supersonic.

11:00 am

The competition heats up: Because its FAA test flight permit will expire on May 23, SpaceShipTwo’s first powered flight has to occur by then and be supersonic.

What is unclear to me is how the expiration of this permit could affect future flights. Does Virgin Galactic have to get a new permit to continue test flights? What about the tourist flights that are supposed to follow?

The last 800 years of ice cores from Antarctica shows that the icecap has apparently been increasing over the last century.

9:48 am

The uncertainty of science: Ice core data from the last 800 years from Antarctica suggest that the icecap has been growing over the last century.

The changes also appear to correlate with solar fluctuations, though there are so many uncertainties here that no single explanation can yet be accepted as the answer.
