Orbital announces revised schedule for its initial Taurus 2 and Cygnus flights

4:26 pm

Orbital Sciences has announced its revised schedule for the initial Taurus 2 and Cygnus flights.

Orbital will conduct a test of the Taurus 2’s first stage on the launch pad in late January [2012], and the inaugural Taurus 2 flight in late February or early March. This will be followed, in early May, by a Taurus 2 flight carrying the Cygnus station cargo vehicle, a flight during which Cygnus is expected to demonstrate its ability to berth with the station. The first operational space station cargo-delivery mission for Taurus 2 and Cygnus will occur in late August or early September under this revised schedule, Orbital officials said.

Based on conversations I’ve had with people at Orbital, this delay was expected, and is a good thing. The company was under incredible time pressure to get ready for a December launch. Given that this will be the first test flight of Taurus 2, and it must work for the Cygnus cargo flights to follow, better they give themselves some working room to get it right.

An independent study of climate suggests the climate has warmed 0.9 degrees Celsius since 1950

2:24 am

An independent study of land temperature records by a team led by Richard Muller concludes that the climate has warmed 0.9 degrees Celsius since 1950.

Does this prove that human-caused global warming is happening? No, not even close. The study has not yet been peer-reviewed, and others have not yet been able to duplicate its results. Also, a warming trending since 1950 can be caused many things, and it is only a very short snapshot of a vastly longer movie.

Nonetheless, it does appear that real science (open data, honest analysis, and a willingness to entertain opposing viewpoints) is beginning to return to the field of climate research. For this we should celebrate.

Elon Musk and the forgotten word

6:48 pm

Elon Musk at National Press Club

When Elon Musk gave his speech at the National Press Club on September 29, he was asked one question to which he really did not know the answer. He faked it, but his response illustrated how completely forgotten is one fundamental fact about American society — even though this fact is the very reason the United States became the world’s most wealthy and powerful nation less than two centuries after its founding.

To explain this fundamental fact I think I need to take a step back and talk about the ongoing war taking place right now over how the United States should get its astronauts into space. On one side we have NASA and Congress, who want NASA to build a new heavy-lift rocket to carry its Orion capsule beyond Earth orbit. On the other side we have a host of independent new space companies, all vying for the chance to launch humans and cargo into space for fun and profit.

Which is right? What system should the United State choose?

GAO and SpaceX blast military’s plans to spend $15 billion for all its launches through 2018 in one purchase

9:51 am

GAO and SpaceX blast the military’s plans to spend $15 billion for all its launches through 2018, in one bulk purchase.

The reason given by the military for buying all these launches up front is to save money. In reality, it is to favor the companies they want to do business with, rather than open up the business to as many competitors as possible.

Gilad Shalit released for 1000 Palestinians

10:37 am

Gilad Shalit has been released for 1000 Palestinians convicted prisoners. And who were these Palestinians? Some examples:

They include the perpetrators of some of the most ghastly terrorist attacks of recent years: Brutal killers like Abd al-Aziz Salehi, who gleefully displayed his blood-soaked hands to a cheering Ramallah crowd in 2000 after lynching two Israelis and mutilating their bodies. Like Ibrahim Yunis, mastermind of a 2003 cafe bombing that left seven innocents dead, including an American-born doctor and his 20-year-old daughter on the eve of her wedding. Like Ahlam Tamimi, a Palestinian television personality who boasts of her role in organizing the 2001 bombing of a pizzeria in downtown Jerusalem, in which 15 people were killed, seven of them children.

The designer of spy satellite finally reveals his life’s work

8:02 pm

The designer of the spy satellite KH-9 HEXAGON (more generally known by its nickname “Big Bird”) has finally been able to describe his life’s work.

What surprised me most from this story is the fact that HEXAGON used film to record its images, not some form of digital or electronic technology. The film was returned to Earth in four “re-entry buckets” that were snatched out of the air by a modified C-130 airplane. I had assumed that by the time HEXAGON was launched they had abandoned film. Not so.

Obama administration has pulled the plug on one part of Obamacare after admiting it cannot work

5:45 pm

The Obama administration has pulled the plug on one part of Obamacare after admitting it cannot work.

Although sponsored by the government, CLASS was supposed to function as a self-sustaining voluntary insurance plan, open to working adults regardless of age or health. Workers would pay an affordable monthly premium during their careers, and could collect a modest daily cash benefit of at least $50 if they became disabled later in life. Beneficiaries could use the money for services to help them stay at home, or to help with nursing home bills.

But a central design flaw dogged CLASS from the beginning. Unless large numbers of healthy people willingly sign up during their working years, soaring premiums driven by the needs of disabled beneficiaries would destabilize it, eventually requiring a taxpayer bailout. After months insisting that problems could be resolved, Health and Human Services Secretary Kathleen Sebelius, finally admitted Friday she doesn’t see how that can be done.

Now we merely have to repeal the rest of this travesty.

Ancient Greek ships shipped more than just wine

5:28 pm

New data has shown that ancient Greek merchant ships transported a wide assortment of goods, not just wine.

What is interesting about this story is how it punctures a hole in an assumption too many archeologists have been making about the amphorae, the standard shipping container of the ancient Mediterranean:

Amphorae have been found in their thousands in wrecks all over the Mediterranean Sea. Some of them contain residues of food, such as olive pits and fish bones, but the vast majority of them are discovered empty and unmarked. Foley says historians tend to assume that these containers were used mainly to transport wine — in a survey of 27 peer-reviewed studies describing 5,860 amphorae, he found that 95% of the jars were described as having carried the beverage.

The new research found evidence for many things besides wine, illustrating again the dangers of assuming anything in science.
