Mars: dry with only periodic short bursts of wetness.
Though this Science article outlines well the present “consensus” for Mars’s past climate, it also tries to make it sound like the planetary science community had once believed that Mars was once ocean-covered like the Earth and now has abandoned that consensus. To this I say bunk. Though many respected planetary scientists have looked for and found evidence for a past ocean on Mars, this possibility has always been controversial. From my readings most planetary scientists have always believed that Mars has generally been dry, interspersed with short periods when there is flowing liquid water on its surface. Even the advocates of the Martian ocean never proposed an Earthlike ocean, but a somewhat shallow and short-lived phenomenon.

Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.
A new consensus: Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.
We, the undersigned, respectfully request that NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites. We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.
The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.
The individuals who signed this letter comprise a who’s-who from NASA’s science and space exploration work over the past fifty years. Their willingness to sign such a letter cannot be dismissed lightly.

Despite protests from the U.S. and South Korea, North Korea is continuing preparations for the launch an Earth observation satellite.
Despite protests from the U.S. and South Korea, North Korea is continuing preparations for the launch an Earth observation satellite.
North Korea recently entered into a food aid agreement with the U.S., which requires the Asian nation to halt long-range rocket launches in exchange for critical resources to stem the country’s widespread poverty and famine.
Officials from the U.S. and South Korea have said that the Unha-3 launch is a violation of this agreement, and could carry significant consequences. South Korean officials have said they may even shoot down parts of the Unha-3 rocket if they breach the state’s borders.

SpaceX is planning its own spaceport about three miles north of Mexico at the southern tip of Texas.
SpaceX had been looking at sites at various potential sites, including ones in Florida, Hawaii and Puerto Rico. Company officials have said they plan to operate out of Cape Canaveral and Vandenberg Air Force Base as well. A third, commercial launch site frees them from range restrictions that exist at the other two locations.

Passover
For the next two days posting will be light. I am in Chicago visiting family for Passover, the annual Jewish holiday celebrating the release of the Jews from slavery in Egypt. During the Seder meal, Jews read the Haggadah, which retells the story of the Jewish slavery in Egypt and their escape, with the idea of reminding each person what is like to be a slave, and then to be free. As it says in the Haggadah,
In every generation each individual is bound to regard himself as if he had gone personally forth from Egypt.
Tonight, this is what Jews do. It would be nice if all people reflected on this and did the same.
Twenty doctors disciplined for giving out fake sick notes at Wisconsin demonstrations last year
Slap on the wrist: Twenty doctors have been fined $500 to $4001 and made to attend ethics training for giving out fake sick notes at the Wisconsin union demonstrations last year.

The actual cost to launch
In writing this short post on the efforts of Lockheed Martin and Orbital Sciences to launch rockets for the small satellite market, Clark Lindsey made this comment:
It costs around $50 million to launch a Orbital Sciences Minotaur 4, which can put 1,730 kg into LEO while the Lockheed’s Athena 2 will cost around $65 million to put 1,712 kg into LEO. SpaceX currently posts charges $54M – $59.5M for launching to LEO 10,450 kg (equatorial) and 8,560 kg (polar). If SpaceX is able to sustain these prices in routine operation, it will obviously result in some disturbance to the launch industry.
Let’s deconstruct these numbers again, this time listing them by the cost per kilogram:

The Obama administrations Treasury Secretary admitted Wednesday that the federal government’s debt is “unsustainable,” but then added that solving the problem shouldn’t be a top priority, because the government still needs to “do things.”
Modern doublethink: The Obama administration’s treasury secretary admitted Wednesday that the federal government’s debt is “unsustainable,” but then added that solving the problem shouldn’t be a top priority, because the government still needs to “do things.”
Geithner’s refusal to confront what he admits is a looming disaster illustrates for all to see the normal operating policies of this administration.

“The bear population is not in crisis as people believed.”
“The [polar] bear population is not in crisis as people believed.”
The number of bears along the western shore of Hudson Bay, believed to be among the most threatened bear subpopulations, stands at 1,013 and could be even higher, according to the results of an aerial survey released Wednesday by the Government of Nunavut. That’s 66 per cent higher than estimates by other researchers who forecasted the numbers would fall to as low as 610 because of warming temperatures that melt ice faster and ruin bears’ ability to hunt. The Hudson Bay region, which straddles Nunavut and Manitoba, is critical because it’s considered a bellwether for how polar bears are doing elsewhere in the Arctic. [emphasis mine]
The study here illustrates again the unreliability of another prediction by scientists advocating global warming. The polar bear population might be under threat, but the evidence so far doesn’t yet support that theory.

Despite lacking a magnetic field of its own, scientists have discovered magnetic storms occurring in the space surrounding Venus.
The finding, reported today in Science1, suggests that magnetic reconnection may generate auroras on Venus, and could have contributed to the loss of a thick, water-rich atmosphere that scientists believe surrounded the planet during its early history, some 4 billion years ago.
