Astronomers take one last close look at 1999 RQ36 before sending mission there

9:05 am

Astronomers plan one last close look at 1,900-foot-wide asteroid before sending a space probe there to collect samples.

Discovered in 1999, the OSIRIS-REx target asteroid, designated 1999 RQ36, nears Earth once every six years. During the 2011 closest approach in early September, it will be 10.9 million miles (17.5 million kilometers) away. In 1999, closest approach was 1.4 million miles (2.3 million kilometers).

Strangely, the article above never mentions the fact that 1999 RQ36 has 1 in a 1000 chance of hitting the Earth in 2182, which to my mind is the primary reason for studying it.

One man’s 9/11 idea to rescue people from high-rise buildings

5:33 pm

One man’s 9/11 idea to rescue people from high-rise buildings.

It involves attaching a harness around your body. Attached to the harness is a Kevlar rope that is secured at one end to a radiator or pipe. You then pop out of a window and rappel down the face of the building using a device which controls the rate of descent at 6 feet per second. Think of it as a fishing reel with a human attached.

NASA and ATK sign new launch development agreement

3:52 pm

At a press conference today, NASA and ATK announced a new launch development agreement, running through March 2012, to help develop ATK’s Liberty solid rocket into a launch vehicle that could bring both cargo and crews to ISS.

The agreement provides ATK no funds, but is designed to give ATK as much support from NASA as possible in developing Liberty, tested fired last week for only the third time. If this initial agreement goes well, it will position ATK to compete for the next round of development subsidizes.

According to ATK, they think they could launch by 2015, and are hoping to provide a rocket capable of flying the spacecraft and freighters of Boeing, Sierra Nevada, Blue Origin, and even SpaceX (should Falcon 9 have problems and they need a rocket to launch Dragon).

How the Palestinian Authority trains children to hate

9:15 am

How the Palestinian Authority trains children to hate:

Classroom incitement has been thoroughly documented as has hate-teach and hate-preach on PA TV and radio, where Jews and Israelis are represented as demonic figures; and the need to wipe Israel off the map is a frequent theme in the eulogies of suicide bombers, martyrs whose deaths in terror attacks intending mass murder endear them to Allah. The goal seems to be to create a seething, raging population of young people far more interested in wiping Israel off the earth’s face than in achieving peaceful coexistence.

And they do not wait until the children start school. Palestinian Authority and Hamas preschool television and radio programming could be called Terrorism for Tots; and such programming continues well into high school. A Hamas weekly program starred a Palestinian version of Mickey Mouse, Farfur, who tells children to pray until there is “world leadership under Islamic leadership” and in the meantime to oppose the “oppressive invading Zionist occupation.” Farfar is ultimately beaten to death by an enraged Israeli “settler,” and is replaced by an intrepid young bee who buzzes the same message to the preschool viewers. Similar messages are encouraged in the classroom with supplementary material and teacher-guided self-expression that encourage martyrdom and glorify terrorism and terrorists.

Read the whole thing. As the author notes, “Can a government so filled with hate and bigotry that they crucify their own children on the cross of jihad and Jew-hatred realistically be expected to develop a nation that will work toward peace?”

Speculation on what the ATK/NASA announcement later today will be about

8:58 am

More speculation here and here on what the ATK/NASA announcement later today will be about. As Jeff Foust notes,

Last Friday NASA announced that the space agency and ATK would announce an agreement this Tuesday “that could accelerate the availability of U.S. commercial crew transportation capabilities”. (The announcement was originally going to be only available to media calling into a telecon line, but NASA said Monday the announcement will be on NASA TV at 3 pm EDT.) The announcement has generated various degrees of glee or despair, depending on one’s opinions about ATK’s work on solid rocket motors it has proposed for its Liberty rocket and is seeking to have incorporated into NASA’s Space Launch System (SLS) heavy-lift rocket.

A giant storm on a distant star

8:56 am

Astronomers have spotted what they think is a giant storm on a distant star.

As part of a large survey of nearby brown dwarfs – objects that occupy the mass gap between dwarf stars and giant planets – the scientists used an infrared camera on the 2.5m telescope at Las Campanas Observatory in Chile to capture repeated images of a brown dwarf dubbed 2MASS J21392676+0220226, or 2MASS 2139 for short, over several hours. In that short time span, they recorded the largest variations in brightness ever seen on a cool brown dwarf.

“We found that our target’s brightness changed by a whopping 30 per cent in just under eight hours,” said PhD candidate Jacqueline Radigan, lead author of a paper to be presented this week at the Extreme Solar Systems II conference in Jackson Hole, Wyoming and submitted to the Astrophysical Journal. “The best explanation is that brighter and darker patches of its atmosphere are coming into our view as the brown dwarf spins on its axis,” said Radigan.

House proposes trimming budget of FAA’s commercial space office

2:36 pm

A House subcommittee has proposed trimming the budget of the FAA’s commercial space office from the $15.2 million it received in 2010 and 2011 to $13 million for 2012.

This is good, to my mind. Cutting their budget will pull the teeth from their regulatory efforts. As the commercial space industry ramps up, the political pressure on this office to approve permits will increase, and if they are short of cash they will have no choice but to keep things simple and say yes.

Update: Thanks to Joe2 for noting my error: the budget numbers above have been corrected to millions, not billions.

$18 billion for one test launch

2:23 pm

NASA thinks it will cost $18 billion to complete and launch in 2017 one test flight of the Congressionally-designed Space Launch System, the program-formerly-called-Constellation.

This is madness. One flight, unmanned, in seven years? No sane customer would ever buy such a product, especially when there are now a number of cheaper competitors who will likely be flying manned in less time.

Note also that even if NASA’s figures are exaggerated, which I am sure some Senators and Congressmen will claim, I would bet that they are not that far off, based on the space agency’s fixed labor costs and past history.

A day to express the value of justice

6:00 am

Updated and bumped: I wrote the following last year on September 11. Sadly, nothing has changed since then. President Obama is still trying to sell the idea that this day should be used as a day of service, something that misses the point so completely as to almost be despicable.

So, I think it is worth repeating what I wrote on September 11, 2010:

The President has asked us to consider today “a national day of service and remembrance”. Though the sentiment seems reasonable, I must respectively disagree.

September 11 should not be turned into a day to celebrate volunteerism or service or American charity. Though these values are profound, important, and an expression of much of what makes our nation great, they are not why we remember September 11.

We remember the evil acts commited on September 11, 2001 in order to remind us that there is evil in the world.

We remember these evil acts so that we will have the strength to fight that evil, with every fiber of our being.

We remember those who died in order to prevent future attacks and further deaths.

We remember so that no one can ever try to make believe these events did not happen.

We remember so that no one can spread the lie that the perpetrators were something other than what they were: Men who had decided to kill in the name of Islam, based on what they believed their religion taught them.

And finally, and most important, we remember the horrible events of September 11, 2001 so that those innocent murdered souls — whose only crime that day was going to work — will not have died in vain.

SpaceX Acknowledges Falcon 9 Engine Anomaly

11:30 pm

This is not good if true: SpaceX has admitted that in its December 2010 test flight of Falcon 9 there was a problem with its first stage.

During the August meeting, held at the Johnson Space Center in Houston, SpaceX told to the two advisory bodies that there had been an engine anomaly during the most recent Falcon 9 launch, according Charles Daniel, a shuttle and space station safety expert at Herndon, Va.-based Valador Inc., and a member of the ISS Advisory Committee. “There was no explanation or root cause analysis or corrective action for this particular anomaly,” Daniel said Sept. 9 during the public meeting. “This is a relatively troublesome statement not to recognize that a premature engine shutdown was a significant event.”

Senate approves a flat budget for the Department of Energy

5:10 pm

The Senate has approved a flat budget for the Department of Energy.

On Wednesday the Senate Appropriations Committee approved $4.843 billion for DOE’s Office of Science in 2012. That’s the same level as this year, and a slight bump over the $4.8 billion approved in July on a largely partisan vote by the House of Representatives covering the entire department. Although the funding is a far cry from the $5.416 billion that the Obama Administration had requested in February for the next fiscal year, which begins on 1 October, officials at the Office of Science’s 10 national labs say they’re not complaining. “Even staying flat when a lot of other programs are getting cut is relatively good news,” says Thom Mason, director of Oak Ridge National Laboratory in Tennessee. In budgets, “flat is the new good,” quips Eric Isaacs, director of Argonne National Laboratory in Illinois. [emphasis mine]

That a government official is now happy that the budget is flat is a good sign that we might finally be making some cultural progress in terms of bringing the federal budget under some control. In the past the very thought of no increase would have sent these people into spasms of outrage. Now they realize how pointless such a tantrum would be, and might actually do their budget negotiations harm.

Unknown objects in space

Fermi list of object types

NASA’s Fermi Gamma-Ray Telescope today released an updated catalog of the last two years of its survey of the sky at high energy emissions. All told, there are 1873 objects in the catalog, more than half of which are supermassive black holes at the center of distant galaxies. You can see this all-sky map below the fold.

Many of the objects are quite familiar, such as the Crab Nebula, the remnant of a supernova that exploded a little less than a thousand years ago.

For decades, most astronomers regarded the Crab Nebula as the steadiest beacon at X-ray energies. But data from several orbiting instruments — including Fermi’s Gamma-ray Burst Monitor — now show unexpected variations. Astronomers have shown that since 2008, the nebula has faded by 7 percent at high energies, a reduction likely tied to the environment around its central neutron star.

Since 2007, Fermi and the Italian Space Agency’s AGILE satellite have detected several short-lived gamma-ray flares at energies hundreds of times higher than the nebula’s observed X-ray variations. In April, the satellites detected two of the most powerful yet recorded. To account for these “superflares,” scientists say that electrons near the pulsar must be accelerated to energies a thousand trillion times greater than that of visible light — and far beyond what can be achieved by the Large Hadron Collider near Geneva, Switzerland, now the most powerful particle accelerator on Earth.

What I, and many astronomers, find even most interesting about this catalog, however, is the large number of completely mysterious objects scattered across the sky, objects that emit powerful gamma rays but are not visible in any other wavelengths. All told, these unidentified objects comprise almost one third of the entire catalog.

Senators lambast Administration for SLS budget numbers

9:12 am

The space war heats up: Two senators have issued a statement lambasting the Obama Administration for its budget numbers for building the program-formerly-called-Constellation.

All of this is fantasy and foolishness. These senators might succeed in forcing NASA to spend money on the heavy-lift rocket that Congress has mandated, but there is no way the space agency will ever get enough funding or time to finish it. Even if the lower estimates are right, the cost is exorbitant, many times that of what the private companies have spent for their rockets and ships. And if construction does begin in earnest, it cannot be finished before the arrival of a new President in 2016 (at the latest), who, like all new Presidents, will have his own plans and will not want to build something started by the previous administration.

Much better to end this farce and save the money, especially considering the debt of federal government.
