Hayabusa ready for launch

9:06 am

In a press photo op the Japanese have unveiled the completed Hayabusa 2, ready for its journey to an asteroid.

Hayabusa 2 will deploy one of five target markers that it will use to guide itself into landing and collecting a sample. It will deploy a European-built lander named MASCOT and three (count them, three) “rovers” called MINERVA-II. I put “rovers” in quotes because I think these are not wheeled rovers but rather bouncy hoppers like Hayabusa 1’s MINERVA (which was deployed but sadly missed Itokawa). Then it will do an experiment like Deep Impact’s, releasing an impactor to make a crater on the asteroid’s surface. But because Hayabusa 2’s impactor won’t have much kinetic energy, they made it explosive. The mothership will have to hide in the shadow of the asteorid as the explosion happens, so they have also added the deployable DCAM3 to try to get a view of the crater’s formation.

Rendezvous is set for around 2018 with the spacecraft’s sample return to Earth sometime in 2020.

Nothing for New Horizons after Pluto

8:57 am

As New Horizons begins its final shake-down in advance of its July 2015 flyby of Pluto, scientists have so far failed to find any Kuiper Belt objects in the right place for it to fly past after Pluto.

They haven’t given up hope, however. The search continues. As for the Pluto flyby,

The hibernating spacecraft will send weekly status beacons back to Earth, with wakeup scheduled for Dec. 7 to begin the final phase of its approach to Pluto. New Horizons will stay awake for two years to prepare for the encounter, fly by Pluto, and downlink science data. The craft’s appointment with Pluto is set for July 14, 2015, when it will zoom about 6,200 miles from the icy world’s unmapped surface for a one-shot chance to explore Pluto’s geology and atmosphere.

All geckos lost from Foton-M4

8:47 am

Upon the return to Earth today of Russian biology satellite Foton-M4 biologists discovered that all the geckos on board had died sometime during the mission.

The cause of death has not yet been announced. The mission itself had some problems, and returned to Earth about two weeks early. Nonetheless, the Russians also announced that flies on board were still alive upon landing.

Woman scares off attackers with gun

1:02 pm

The right kind of gun control: An Ohio woman with a concealed carry license scared off two bat-wielding attackers when she pointed her gun on them.

This is not that unusual a story but I wanted to highlight it because of this quote:

The men took off and so far have eluded police. Dinah posted about the incident on Facebook to alert friends and neighbors, to criticism by some. “Most of the males’ opinion was, ‘Why didn’t you shoot them?'” [emphasis mine]

The highlighted quote above, nonchalantly advocating that she should have fired the gun, is incredibly stupid. Life is not a modern Hollywood movie, where idiots shoot their weapons indiscriminately without thought. This woman made exactly the right decision. She used her weapon to stop the attack, and then proceeded on her way. Had she fired she would made things very messy for herself, for no reason.

Guns in the hands of good people are without question the best defense against bad people. However, if you use that gun unwisely or without cause you make yourself a bad person. Stay good and stay safe. Arm yourself, but don’t use your weapon unless you really really really have to.

Professor with leftwing ties to build hate speech database.

9:53 am

The Indiana professor who is going to build a database for the federal government to “detect political smears, astroturfing, misinformation, and other social pollution” turns out to have numerous links to and is a strong supporter of left wing causes.

“‘Truthy’ claims to be non-partisan. However, the project’s lead investigator Filippo Menczer proclaims his support for numerous progressive advocacy groups, including President Barack Obama’s Organizing for Action, Moveon.org, Greenpeace, the Sierra Club, Amnesty International, and True Majority. Menczer, a professor of informatics and computer science at Indiana University, links to each of the organizations on his personal page from his bio at the Center for Complex Networks and Systems Research.”

Menczer of course has denied his database will have any partisan tinge. He is as pure as the wind-driven snow!

Battle of the heavy lift rockets

9:44 am

Check out this very detailed and informative look at unstated competiton between NASA’s SLS rocket and SpaceX’s heavy lift rocket plans that are even more powerful than the Falcon Heavy.

Key quote: “It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn’t set to be launched until the 2030s.”

The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far far far less money.

Opportunity to get a reboot

9:32 am

Because of an increasing number of computer resets on the Mars rover Opportunity, engineers plan to reformat the rover’s computer.

The resets, including a dozen this month, interfere with the rover’s planned science activities, even though recovery from each incident is completed within a day or two.

Flash memory retains data even when power is off. It is the type used for storing photos and songs on smart phones or digital cameras, among many other uses. Individual cells within a flash memory sector can wear out from repeated use. Reformatting clears the memory while identifying bad cells and flagging them to be avoided.

Obviously there is a risk, though small, that this action will not work and the mission will end here. Stay tuned.

The decision on manned spaceflight

9:23 am

The rumors are swirling. Today alone the news included three different articles about NASA’s upcoming decision to down-select to either one or two in its manned commercial crew program.

The third article above speculates that the decision will be made shortly after this weekend, maybe as soon as next week. It also outlines in nice detail the companies who are competing for the contract.

I strongly expect NASA to pick two companies, not one, as the agency has repeatedly said it wants to have redundancy and competition in manned space flight. To this I agree whole-heartedly. Right now, if I was a betting man (which I am not), I would pick SpaceX and Sierra Nevada as the two companies to get the nod.

If NASA only picks one company that I don’t think there is much doubt that it will be SpaceX.

And then again, government agencies, because of politics, have sometimes made some incredibly stupid decisions. For example, back in the 1970s the company that proposed the space shuttle was rejected for another big space company that had more political clout, which then turned around and essentially stole the first company’s designs to build the space shuttle from them. It just took longer and cost more.

The X-37B just keeps going.

2:56 pm

The Energizer bunny of space: The X-37B has now completed more than 600 days in orbit, with no indication when it will return to Earth.

The Air Force is believed to have only two X-37B space planes. These space planes have flown at otal of three missions, which are known as OTV-1, OTV-2 and OTV-3. (“OTV” is short for Orbital Test Vehicle.) The first mission blasted off in April 2010, and the craft circled Earth for 225 days. The second X-37B vehicle launched in March 2011, performing the OTV-2 mission. This spaceflight lasted 469 days, ultimately landing at Vandenberg Air Force Base in California in June 2012. That was the same landing site OTV-1 used after completing its mission.

The current OTV-3 mission is reusing the first X-37B space plane from the OTV-1 flight, showcasing the reusability aspect of the program.

Fewer people to have health insurance under Obamacare

2:42 pm

Finding out what’s in it: A new analysis of Obamacare predicts that in the next ten years the number of uninsured Americans will increase by 10 percent while premiums will continue to rise.

We estimate that average annual costs for the cheapest individual plans—the “bronze” plans—may increase by 96 percent, from roughly $2,100 to nearly $4,200. Bronze family plans prices, meanwhile, may increase by nearly 50 percent. The average plan in this category could come close to $13,000 a year in total premiums. Almost every plan will see a price increase of some kind.

Consumers will learn these unpleasant truths in the fall of 2016 when they attempt to extend their policies.

No matter where you live, the effects will ripple across the entire industry. The dramatically higher prices will almost surely drive some consumers out of the exchanges. But they won’t have many places to turn. Many—perhaps most—won’t be eligible for Medicaid, while others won’t have jobs that offer replacement health insurance. People in this position will thus choose between health insurance they can’t afford and becoming uninsured. Not even the IRS penalty will convince everyone to bite the bullet.

Prior to 2016 the law allows insurance companies to use tax dollars, subsidizes from the federal government, to artificially depress premiums. After 2016 that option disappears, and the real cost of Obamacare gets passed to the consumer, most of whom will not be able to afford it.

British government raises terror threat

9:47 am

Update: Sources in the federal government say that an Islamic terror attack coming from Mexico is imminent.

Original post:
While Obama has admitted he has no strategy to deal with ISIS, the British government today raised its terror threat level to “severe.”

[Home Secretary Theresa] May said the threat level was raised because of the risk from the deteriorating situation in Iraq and Syria, where extremist militants from the group calling itself the Islamic State (also ISIS or ISIL). May said, however, that there was no specific threat to Britain that caused the raise in the terror level. This is the first time Britain’s terror threat level has been at “severe” since 2011. “The increase in the threat level is related to developments in Syria and Iraq where terrorist groups are planning attacks against the West. Some of these plots are likely to involve foreign fighters who have traveled there from the UK and Europe to take part in those conflicts,” May said in a statement.

Add to this the fact that U.S. intelligence has noted a “significant increase” in chatter among terrorist organizations as September 11 approaches.

Islamic terrorists have celebrated September 11 several times previously with terrorist attacks. We shouldn’t be surprised if they do it again, especially as they now have a resurgent base of operations with many resources in the territory now controlled by ISIS.

Barack Obama meanwhile will probably find out about the next terrorist attack from a newspaper he reads, after he finishes his next very important round of golf.

Single sensor caused Falcon 9R failure

9:21 am

SpaceX has identified the cause of the failure of last week’s Falcon 9R test flight failure as a single sensor.

On the Falcon 9R, there was no backup for this sensor, so the rocket was required to self-destruct when the sensor failed. On a Falcon 9, other sensors would have picked up the slack and the rocket would have continued in flight.

That the sensor is used by the Falcon 9, however, explains why they have delayed the next commercial flight. They probably want to make sure they understand why the sensor failed so they can reduce the chance of failure on the Falcon 9.

Spitzer spots asteroid collision

11:57 am

A monitoring program of a young star by the Spitzer Space Telescope has paid off with evidence of a major collision between asteroids in the debris disk that surrounds the star.

Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013. “We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now smashing themselves into smithereens and slowly leaking away from the star,” said lead author and graduate student Huan Meng of the University of Arizona, Tucson.

While dusty aftermaths of suspected asteroid collisions have been observed by Spitzer before, this is the first time scientists have collected data before and after a planetary system smashup. The viewing offers a glimpse into the violent process of making rocky planets like ours.

Court rules in favor of rock throwers and thugs

7:34 pm

In a ruling today a court has ruled that the police have the right to curtail the free speech of Christians on a public street if Muslims threaten them with violence.

Let me describe what happened again that so there is no confusion. There was a Muslim festival open to the general public on the streets of Dearborn, Michigan. Some Christians wanted to walk through that festival holding signs and preaching the gospel. They were attacked by a mob. The police, instead of arresting the attackers, threatened the Christians with arrest if they didn’t shut up and leave.

If you doubt me, watch the video of that event, which I posted when it happened under the title The Stoning of Christians — in Michigan.

In essence, the court has sanctioned the heckler’s veto. If you don’t like what someone is saying, threaten them with violence and the police will shut them up for you so that you don’t behave badly.

SLS first launch officially delayed one year

3:18 pm

In a press conference today to tout the development of the SLS rocket, NASA finally admitted that the rocket’s first flight has been delayed a year until 2018, as had been rumored for months.

The cost? $7 billion more from now until that first launch, a number that does not include the billions already spent. I once again note that the entire commercial program, both manned and cargo, has cost less than that, from start to finish, and includes the entire manifest of actual cargo flights to ISS.

The federal government wants to know what you are saying

10:09 am


What could go wrong? The federal government is spending almost a million dollars to make it possible to track “misinformation” and hate speech on Twitter.

The National Science Foundation is financing the creation of a web service that will monitor “suspicious memes” and what it considers “false and misleading ideas,” with a major focus on political activity online. The “Truthy” database, created by researchers at Indiana University, is designed to “detect political smears, astroturfing, misinformation, and other social pollution.” The university has received $919,917 so far for the project.

Anyone want to make a bet that the only ones who will be labeled with “political smears, astroturfing, misinformation, and other social pollution” will be conservatives?

The DOT wants to know where you are

9:52 am

What could go wrong? The DOT has proposed that all new cars be required to broadcast their location and speed.

They claim that this data could be used to provide drivers with a warning if their vehicle might be getting too close to another vehicle. It will also be necessary to make driverless cars more reliable.

I wonder what other uses this information could have.

Russian military abandons Rokot

9:35 am

Beginning in 2016, the Russian military will stop using its Rokot launcher, switching to Soyuz and Angara rockets instead.

The reason? Rokot relies on some imported parts, while Soyuz and Angara are build entirely in Russia.

It is interesting how fast the Russians are moving to stop their dependence on foreign parts, compared to the United States. Rather than try to build Russian-built parts for Rokot, they have taken the simplest and fastest approach and simply switched rockets.

In the U.S. Congress is instead demanding that a new rocket engine be build for Atlas 5 to replace the Russian engine, an expensive and time-consuming process. Wouldn’t it make more sense to say buy-buy to Atlas 5 and just switch to the Falcon 9?

A tugboat for satellites

9:21 am

The competition heats up: An Israeli start-up is building a satellite tugboat that could be used to move stranded satellites to their proper orbits.

The planned satellite, once built and deployed, should be able to rendezvous with in-orbit satellites and propel them into new orbits, give them course corrections, or steer them towards what’s known as the “graveyard orbit” – a decommissioned satellite graveyard some 300km above their usual height of 36,000 kilometers over the equator. This fuel saving can extend a communications satellite’s life.

The company says its tugboat design could be a possible solution to two stranded Galileo Project satellites, now in possibly unusable orbits following a launch malfunction over the weekend.

The spacecraft would use an ion engine for propulsion.

Rosetta’s camera zooms in

9:10 am

67P/C-G on August 23, 2014
Comet 67P/C-G as seen on August 23, 2014 from 38 miles.
Click on image for uncropped version.

The Rosetta team has begun releasing more close-up images of Comet 67P/C-G taken by the spacecraft. The image to the right was taken by the navigation camera, but rather than capture the entire nucleus in a single image the camera is now zoomed in and taking a mosaic of four images. This picture is one quarter of that mosaic.

Note the boulders and the sharp peaks in the image. The boulders are important to map for planning Philae’s landing site. The sharp peaks suggest recent outgassing.
