SDO celebrates its fifth year in space with a time-lapse of the Sun

9:40 am

Cool images! In celebration of Solar Dynamics Observatory’s fifth year in space observing the Sun, the scientists at the Goddard Space Flight Center have released a time-lapse movie showing the Sun for the past five years.

Video below the fold. It is astonishing and hypnotic. The movie images were taken one image every 8 hours beginning in 2010. If you compare the Sun at the beginning of the movie with the end, you can see the slow shifting of sunspots/flares from higher to equatorial latitudes, as is normal as the solar cycle ramps up to solar maximum and beyond.

Week long movie of Pluto produced by New Horizons

10:28 pm

Cool images! Using New Horizons’ long range camera scientists have compiled a movie showing Charon and Pluto orbiting each other during the last week of January 2015.

Pluto and Charon were observed for an entire rotation of each body; a “day” on Pluto and Charon is 6.4 Earth days. The first of the images was taken when New Horizons was about 3 billion miles from Earth, but just 126 million miles (203 million kilometers) from Pluto—about 30% farther than Earth’s distance from the Sun. The last frame came 6½ days later, with New Horizons more than 5 million miles (8 million kilometers) closer.

The wobble easily visible in Pluto’s motion, as Charon orbits, is due to the gravity of Charon, about one-eighth as massive as Pluto and about the size of Texas.

Our view of Pluto, and Charon, is only going to get better as New Horizons zooms towards its July fly-by.

Virgin Galactic opens facility for developing LauncherOne

10:20 pm

The competition heats up: Virgin Galactic announced today the establishment of a new facility to design and build the company’s LauncherOne rocket, aimed at putting into orbit very small cubesats at a very low price.

LauncherOne is an air-launch system for satellites weighing up to 225 kilograms. The system will use the same aircraft, WhiteKnightTwo, as the company’s SpaceShipTwo suborbital vehicle, but replaces SpaceShipTwo with a two-stage launch vehicle using engines fueled by liquid oxygen and kerosene.

At the Federal Aviation Administration Commercial Space Transportation Conference Feb. 4, William Pomerantz, vice president of special projects for Virgin Galactic, said the company has already tested engines and other “core infrastructure” of LauncherOne. “We are a fairly vertically-integrated team,” he said. “We really do control a lot of the production in house.”

As the article notes, Virgin Galactic is investing in OneWeb, which hopes to launch a constellation of 650 cubesats to provide broadband communications worldwide. It is likely that a partnership between the two companies exists to put many of those cubesats into orbit with LauncherOne.

This announcement also suggests to me that Virgin Galactic is beginning to shift its gaze from suborbital space tourism to orbital launch services, and in doing so is looking for new ways to make its investment in WhiteKnightTwo pay off.

Abraham Lincoln – a tribute on his birthday

6:01 pm

An evening pause: As I have done before, on Lincoln’s birthday it behooves us to remember him.

We should also remind ourselves, especially in this time of increasing anger, bigotry, and violence, of these words from his second inaugural address, spoken in the final days of a violent war that had pitted brother against brother in order to set other men free:

Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman’s two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said “the judgments of the Lord are true and righteous altogether.”

With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation’s wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.

The endless and all-compassing terrors of global warming

4:23 pm

Want to know what scientists have predicted climate change will do to the Earth? Go to ClimateChangePredictions.org, where they keep a full list of every prediction they can find.

I especially like the category “Having it both ways,” where they list different predictions that insisted on opposite consequences. For example did you know that global warning is going to bring both “less rain” and “more rain”, Other predictions are equally amusing.

Another Falcon 9 launch success

4:14 pm

The competition heats up: A Falcon 9 rocket today successfully put a NASA solar observation satellite into orbit.

They have also said that they have achieved splashdown of the first stage, though no details yet on how soft that splashdown was.

Update: SpaceX reports that “the first stage successfully soft landed in the Atlantic Ocean within 10 meters of its target. The vehicle was nicely vertical and the data captured during this test suggests a high probability of being able to land the stage on the drone ship in better weather.”

No barge landing attempt today for Falcon 9

2:15 pm

Because of high seas SpaceX will not attempt to land its Falcon 9 first stage on its floating barge today.

The drone ship was designed to operate in all but the most extreme weather. We are experiencing just such weather in the Atlantic with waves reaching up to three stories in height crashing over the decks. Also, only three of the drone ship’s four engines are functioning, making station-keeping in the face of such wave action extremely difficult.

They will still attempt a soft splashdown of the first stage in the ocean.

Though this kind of repeated soft splashdown test is essential to prove their ability to bring the first stage down safely, it certainly isn’t as exciting as landing the first stage on a barge. Nonetheless, in previous attempts they have been unable to get really good video of the soft splashdown. Maybe they will do better this time, though the high seas suggest it won’t be easy.

Sunspot activity tracks prediction

1:43 pm

On Monday NOAA posted its monthly update of the solar cycle, showing the sunspot activity for the Sun in January. As I do every month, I am posting it here below the fold, with annotations to give it context.

As I have noted previously, the ramp down from solar maximum continues to track the 2009 prediction of the solar scientist community (indicated by the red curve) quite closely. As NOAA also notes,

While awaiting final confirmation, all evidence points to the most recent solar maximum having peaked at 82 in April, 2014. This was within the expected range for the peak, but occurred significantly later than predicted.

Since their graph doesn’t show the entire curves for their predictions, the above statement seems reasonable. However, looking at the graph with those curves inserted (see my annotated graph below the fold), it becomes clear that not only did the peak occur much later than predicted, the maximum’s overall activity was also generally less than predicted.

IRS steals widow’s savings

11:11 am

Theft by government: The IRS has seized nearly $19,000 of a widow’s savings because it didn’t like the manner in which she deposited it in the bank.

After [an October policy change that was supposed to stop most of these kinds of cash confiscations], federal prosecutors in Iowa agreed to return money the IRS seized from two people accused of structuring, including a restaurant owner who had $33,000 taken and a doctor who fought to get back $344,000 in earnings from his medical practice. But prosecutors declined to drop the civil forfeiture case over $18,775 the IRS seized from [the widow Janet] Malone.

Instead, they added a misdemeanor criminal charge last week alleging she willfully violated the law, after her husband had been warned about the practice four years ago. Malone is expected to plead guilty next week and let the government keep the money, under a plea agreement filed Monday. The charge carries up to one year in jail and a $250,000 fine.

Note that in every one of these cases, no actual crime was every committed. The money was earned legally. The only issue was the manner in which the individuals deposited the money. The IRS didn’t like it.

Rosetta preps for close fly-by of Comet 67P/C-G

9:12 am

Single frame image

Cool image time! In preparation for a close fly-by of Comet 67P/C-G on Saturday — where it will zip past the comet less than three miles above its surface — Rosetta has eased away to a distance of about 60 miles, allowing its navigation camera to snap its first single frame image since the spacecraft’s initial close approach last summer.

The image brightness has been adjusted to make the plume more obvious. Also, if you look closely at the full resolution version of the image, it is possible to see the dusty material that forms the coma surrounding the nucleus.

The last two satellites in Russia’s missile warning constellation have failed.

8:55 am

In January the last two satellites in Russia’s ballistic missile warning system shut down, with the first of the next generation replacement constellation not scheduled to launch until June.

“Oko-1 was part of Russia’s missile warning system. The system employed six satellites on geostationary and highly elliptical orbits. The last geostationary satellite got out of order in April last year. The two remaining satellites on highly elliptical orbits could operate only several hours a day. In the beginning of January, they also went out of order,” Kommersant said.

The new generation early warning satellite Tundra was planned to be launched in 2013. However, the launch was postponed several times as the apparatus was not ready to be put into operation, sources in the aerospace industry told the daily.

Increasingly I am reminded of the Cold War, when our competition was the bloated, inefficient, and poorly managed Soviet Union. The communist nation was definitely a threat, as they got a lot accomplished through sheer brute force and determination. Their long term problem was that it was an amazingly inefficient system, guaranteed to eventually fall apart.

Europe test flies its engineering prototype space plane

8:44 am

The competition heats up: Europe today successfully launched and landed its Intermediate Experimental Vehicle (IXV) space plane.

More details here. And here.

As of 9 pm (Eastern) Wednesday the recovery ship was still “hurrying” to reach the ship, which was being held afloat with “balloons.” Update: The spacecraft has been retrieved.

This prototype is not full scale. It is only about 16 feet long, and was built as a testbed. Whether Europe follows up with a full scale version remains completely unknown. I am skeptical, as this program reminds me of many deadend NASA experimental programs like it, used to try out cool engineering technologies as well as provide pork to Congressional districts without any plans to proceed to the real thing. In the case of IXV, the Italians got most of the pork.

Unions discover Obamacare sucks

5:45 pm

Finding out what’s in it: Because of required Obamacare regulations and taxes on their union health plans, the unions representing workers at 29 west coast commercial ports are now threatening to strike and shut the ports down.

Obamacare imposes a 40 percent tax on health benefits deemed too generous by the government. Health benefits exceeding $10,200 a year in value for individuals or $27,500 for families are defined as “Cadillac” plans and are subject to the tax. Health benefits for longshoremen exceed $40,000 per employee, meaning the union would be served an enormous tax bill when the penalty is imposed in 2018. The longshoremen’s contract expired in July, 2014 and contract talks have stalled, in large part, over whether workers or employers will pay the new Obamacare tax.

But hey, these unions voted for and continue to support the Democratic Party without question, even as the Democratic Party continues to block any repeal or changes to Obamacare. To these union leaders, it all must be Bush’s fault!

The sideshow of Netanyahu’s speech to Congress

12:01 pm

The report notes the increasing flood of Democrats who say they will boycott Israeli prime minister Benjamin Netanyahu’s speech to Congress next month. It also makes this cogent point:

In a sane world, as soon as Netanyahu expressed an interest in speaking, Boehner and McConnell could have responded to both the Prime Minister and our President and said it was a fine idea, set up a time and moved forward. If Obama didn’t want this to be a mess and conceivably even find a way to turn it into an advantage, he could have extended an offer to meet privately with Bibi before the speech or even show up at it with him. That would have presented a unified front between two allies for the rest of the world and the whole thing could have been a done deal by now. There’s nothing remarkable about a world leader making a speech in Washington. It’s pretty much what the place exists for.

While the House Republicans have worked this event for their own political advantages, their invitation to Netanyahu did no harm to American interests or our ally. Obama and the Democrats however have done everything they can to push back politically, even though their push back apparently threatens our ally while damaging our interests in the Middle East.

To put it another way, ask yourself whose actions are doing real harm to the diplomatic relations between the United States and Israel? Who is rejecting an ally and refusing to talk or listen to him?

Update: Check out this very pointed column noting the different reactions of the President and the Democrats to two identical invitations from Congress: “A Jew and a Catholic were invited to Congress…”

Obama administration stonewalls IRS investigation

11:50 am

Working for the Democratic Party: The Obama administration has denied an entire freedom of information request from the web news outlet The Hill in connection with the IRS scandal and the administration’s harassment of its political opponents.

The Hill asked for 2013 emails and other correspondence between the IRS and the Treasury Inspector General for Tax Administration (TIGTA). The request specifically sought emails from former IRS official Lois Lerner and Treasury officials, including Secretary Jack Lew, while the inspector general was working on its explosive May 2013 report that the IRS used “inappropriate criteria” to review the political activities of tax-exempt groups.

TIGTA opted not to release any of the 512 documents covered by the request, citing various exemptions in the law. The Hill recently appealed the FOIA decision, but TIGTA denied the appeal. TIGTA also declined to comment for this article.

This denial is essentially another example of the Obama administration defying the law, as they really don’t have any right to refuse to release these documents. The Freedom of Information law was expressly written to force government agencies to release documents in these kinds of circumstances, not hold them back.
