Voyager 1 has found the edge of the solar system to be far more complex than predicted by scientists.

The uncertainty of science: Voyager 1 has found the edge of the solar system to be far more complex than predicted by scientists.

Scientists had assumed that Voyager 1, launched in 1977, would have exited the solar system by now. That would mean crossing the heliopause and leaving behind the vast bubble known as the heliosphere, which is characterized by particles flung by the sun and by a powerful magnetic field.

The scientists’ assumption turned out to be half-right. On Aug. 25, Voyager 1 saw a sharp drop-off in the solar particles, also known as the solar wind. At the same time, there was a spike in galactic particles coming from all points of the compass. But the sun’s magnetic field still registers, somewhat diminished, on the spacecraft’s magnetometer. So it’s still in the sun’s magnetic embrace, in a sense.

It is now reported that the charges against the high school who refused to remove his NRA t-shirt have been dismissed.

It is now reported that the charges against the high school who refused to remove his NRA t-shirt have been dismissed.

No details yet, however, so it might be too soon to celebrate the return of sanity to this small spot in West Virginia.

Update: The dismissal of charges is confirmed. I think the prosecutor saw the political winds and decided he’d be a fool to pursue this case.

The Commodity Futures Trading Commission today announced that it has filed charges against former Democratic Governor/Senator Jon Corzine for his part in the embezzlement of customer funds at MF Global.

The Commodity Futures Trading Commission today announced that it has filed charges against former Democratic Governor/Senator Jon Corzine for his part in the embezzlement of customer funds at MF Global.

The article says that most of the embezzled funds have been recovered, but that’s not only news to me, I don’t see how it’s possible. We are talking about the misuse and loss of one billion dollars.

Kepler’s planet-hunting predecessor, COROT, has been shut down.

Kepler’s planet-hunting predecessor, CoRoT, has been shut down.

CoRoT suffered a computer failure on November, 2, 2012 and although the spacecraft is capable of receiving navigational commands, the French Space Agency CNES reports it can no longer retrieve data from its 30-centimeter telescope. After a valiant effort to try and restore the computer, CNES announced this week that the spacecraft has been retired. CoRoT’s journey will come to a fiery end as it will be deorbited and it will burn up on re-entry in Earth’s atmosphere.

CoRoT found 32 exoplanets with at least a hundred more candidates still to be confirmed.

Two researchers have concluded that sterilizing spacecraft heading to Mars is largely a waste of money.

Two researchers have concluded that sterilizing spacecraft heading to Mars is largely a waste of money.

As far as Mars is concerned, say Fairén and Schulze-Makuch, such efforts are probably in vain since “Earth life has most likely already been transferred to Mars.” Meteorite impacts have had 3.8 billion years to spread Earth life forms to Mars. Several Earth spacecraft have visited Mars without undergoing the sterilization procedures now in place. If organisms transferred to Mars over the eons failed to survive, modern organisms would likely face the same fate. If they did survive, say Fairén and Schulze-Makuch, “it is too late to protect Mars from terrestrial life, and we can safely relax the planetary protection policies.”

They also note that NASA’s “Office of Planetary Protection is like an interplanetary Environmental Protection Agency” and that its “‘detailed and expensive’ efforts to keep Earth microorganisms off Mars are making missions to search for life on the red planet ‘unviable.’”

The remarkable remains of a most recent supernova.

The remarkable remains of a most recent supernova.

Astronomers estimate that a star explodes as a supernova in our Galaxy, on average, about twice per century. In 2008, a team of scientists announced they discovered the remains of a supernova that is the most recent, in Earth’s time frame, known to have occurred in the Milky Way. The explosion would have been visible from Earth a little more than a hundred years ago if it had not been heavily obscured by dust and gas. Its likely location is about 28,000 light years from Earth near the center of the Milky Way.

Arianespace will not be able to set its launch manifest for the remainder of this year until late July.

7:09 pm

The competition heats up: Arianespace will not be able to set its launch manifest for the remainder of this year until late July.

The year’s third Ariane 5 mission is scheduled for launch in late July carrying the large Alphasat satellite for mobile satellite services operator Inmarsat of London and the European Space Agency (ESA); and India’s Insat-3D telecommunications satellite.

Beyond that, Israel said, it is unclear which commercial payloads will be placed on which of the two remaining Ariane 5 flights, scheduled for this fall, or what the Ariane 5 manifest looks like for 2014. A big question is whether Arianespace has any slots open in the Ariane 5 manifest in 2014 to accommodate new customers who want to switch to Ariane 5 because their selected vehicle is late.

This article not only suggests that Arianespace has more business than it can handle, it is also provides evidence that the company is scrambling to cut costs in order to compete.

The prosecutors trying to put a high school teenager in jail for a year because he refused to take off his NRA t-shirt have tried to put a gag order on the teenager and his parents.

8:51 pm

The new America: The prosecutors trying to put a high school teenager in jail for a year because he refused to take off his NRA t-shirt have tried to put a gag order on the teenager and his parents.

Prosecutors said they wanted to stop White, Marcum, and Marcum’s fathern Allen Lardieri, from sharing their story with the press, claiming the gag order would serve Marcum’s better interest. “These are the same individuals that are trying to prosecute him, so as far as them knowing what is in his better interest, I have a lot of questions about that,” Lardieri said.

A petition to intervene in the gag order hearing on behalf of WOWK-TV and the free press was prepared. Before WOWK reporter Charlo Greene could deliver the petition to the court clerk, she was asked twice to leave the courthouse by a bailiff who told her Judge Eric O’Briant, who presided over Marcum’s case, had requested she be removed from the courthouse. Greene then was told she would be arrested and charged with obstructing an officer if she did not comply with the bailiff’s orders.
