OSIRIS-REx to get more fuel for its asteroid mission

10:17 am

In what might be a first for the planetary science/engineering community, an unmanned probe, being built to bring samples back from the asteroid Bennu, is turning out to be lighter than expected, thus allowing engineers to stuff its tanks with extra fuel to extend its mission.

The OSIRIS-REx spacecraft, being built at a Lockheed Martin facility in Denver, is coming in lighter than the lift capability of the Atlas 5 rocket, which will lift off in its “411” configuration with a four-meter payload fairing, a single-engine Centaur upper stage, and one strap-on solid rocket booster.

The proposal — described as a “heavy launch option” — would add an extra 341 pounds of fuel to the spacecraft’s fuel tank.

Planetary probes never end up lighter than planned, at least until now. During construction scientists have always found it impossible to resist adding more instruments or capabilities, and thus engineers always struggle to get the spacecraft built within its weight budget. For OSIRIS-REx to have this wonderful problem is surely astonishing.

Astronomers find an invisible dwarf galaxy

10:05 am

Using dark matter data that suggested the existence of a faint dwarf galaxy 300,000 light years away on the other side of the Milky Way, astronomers have pinpointed its location by finding a tiny cluster of bright Cepheid variable stars, also located at that distance.

“These young stars are likely the signature of this predicted galaxy,” said Chakrabarti, assistant professor in RIT’s School of Physics and Astronomy. “They can’t be part of our galaxy because the disk of the Milky Way terminates at 48,000 light years.” Invisible particles known as dark matter make up 23 percent of the mass of the universe. The mysterious matter represents a fundamental problem in astronomy because it is not understood, Chakrabarti said.

This result is intriguing because it not only found a previously unknown dwarf galaxy orbiting the Milky Way, it also provides further evidence that dark matter, whatever it is, does exist. The dark matter of this unseen dwarf galaxy showed its gravitational effects on Milky Way stars, and when the astronomers looked at the right spot suggested by those effects, they found distant stars that had to belong to the invisible dwarf galaxy, proving it was there. This is comparable to finding Neptune and Pluto by analyzing their gravitational effects and then predicting their location in the sky.

Five years later a second attempt to put a Japanese spacecraft into Venus orbit

9:55 am

If at first: After failing to place its Akatsuki spacecraft into orbit around Venus in 2010 because of a cracked engine nozzle, Japan has announced its plans for a new attempt later this year.

The attempt will be made on December 7. If successful, the spacecraft will begin studying Venus’s climate and atmosphere only a short time after the end of Europe’s very success Venus Express mission.

“It is ironic a sign warning of the liberal thought police was potentially stolen by the liberal thought police.”

1:45 am

Leftwing facists: A sign advertising a talk being given by Jonah Goldberg about his book Liberal Fascism at the University of Michigan was apparently stolen by liberal fascists who don’t like freedom of speech.

The sign was bright red and declared: “Warning: Liberal thought police. Jonah Goldberg on his best-selling book Liberal Fascism.” It included a picture of a smiley face with a piece of tape over its mouth and the word “censorship.” “The biggest irony is on the front of the poster it says ‘thought police,’” Audia said in an interview with The College Fix. “So a warning on thought police was censored. It’s pretty ridiculous.”

Now of course, we really don’t know exactly who stole the sign, but somehow I don’t believe it was tea party protesters offended by Goldberg’s subject matter. Moreover, such actions have become the typical behavior leftwing students and administrators on college campus.

Annual fund-raiser plus lower price for Genesis

11:20 pm


As this year’s birthday fund-raiser ends, I once again want to thank everyone who donated or subscribed to Behind the Black. I appreciate every penny, in ways that are hard to describe.

And though the official fund-raiser is over and this post will now slowly drop down the page like all other posts, don’t think that donations or subscriptions are no longer necessary. To repeat: If you are a regular reader and like what I do here, please consider making a contribution to help defray the costs for running this website. The tip jar on the right will allow you to make a one time contribution, or even subscribe, making monthly contributions as low as $2.

Please consider helping. Without your financial aid I am not sure I will be able to continue this website into the future.

Also, for those who missed the December sale of Genesis: the Story of Apollo 8, I have good news. We have officially lowered the price of the ebook to $5.99, before discount. You can now get it at this lower price at all ebook venders. Some vendors, such as amazon.com, will discount this price even further.

“Oh, she’s going down.”

10:05 am

Rand Paul today became the fourth senator to announce his opposition to Loretta Lynch, Barack Obama’s nominee for attorney general.

Earlier Wednesday, in his office in the Russell Senate Office Building on Capitol Hill, Breitbart News watched as the senator’s legal and press team briefed him final time before the interview. Sergio Gor, Paul’s communications director, his press secretary Eleanor May and attorney Brian Darling were all present.

Paul asked the team about Sen. Ted Cruz’s (R-TX) question during Lynch’s Senate Judiciary Committee confirmation hearing about whether she’d oppose using a drone to kill an American citizen on American soil.

When Paul heard about her non-answer—she wouldn’t commit that the federal government does not have such authority—he was incredulous. Furthermore, Paul was appalled that Lynch came out in favor of President Barack Obama’s executive amnesty and the use of asset forfeiture—where the federal government seizes people’s property sometimes with flimsy reasoning, something even the Obama administration has offered slight opposition to—and then told his office staff he’s going to oppose her and aim to derail her nomination chances. “Oh, she’s going down,” Paul said to the room.

The video of Lynch’s non-answer to Cruz’s question is quite shocking. I dare you to watch it and tell me afterward that this administration and Democratic Party is not a threat to your freedom and rights.

Whether the Republicans in the Senate will have the courage to stand up to this threat, however, remains a very big unknown. That four senators have announced their opposition so early is a good sign, but we shall see.

Obama: all religions the same

9:49 am

At his speech today at the National Prayer Breakfast President Obama outlined the moral equivalency between Islam and all other religions, noting that all religions have in the past been “hijacked” by evil people for “for their own murderous ends.”

This is an interesting intellectual argument that is completely meaningless in today’s world. The problem today is not Christian murderers or Jewish murderers or Buddhist murderers. It is Islamic murderers, supported by an Islamic population willing to condone violence in the name of their religion.

You don’t believe me? Then compare the large number of demonstrations in the Islamic world protesting the publication of cartoon drawings of Mohammed by Charlie Hebdo versus the complete lack of outrage in those same places for the burning alive of one prisoner and the beheading of others by the Islamic State. Even if Obama is right, which I do not believe, Islam today is murderous and running amok. We must deal with that reality, not the ivory tower delusions of college professors and incompetent Presidents living in the past.

The Russian spaceport construction still behind schedule

9:31 am

In a detailed update on the status of Russia’s new Vostochny spaceport, russianspaceweb reports that the construction continues to be behind schedule.

Whether they can meet the government imposed deadline of first Soyuz rocket launch by the end of 2015 seems very doubtful. More significant is this interesting quote:

In the meantime, various sensitive systems, which arrived to Vostochny for installation into unfinished facilities, were rusting inside their containers along railway sidings.

Obviously, without enough qualified personnel at the remote construction site, Spetsstroi had little choice but to focus on facilities with the highest profile for visiting Moscow officials. Moreover, the work had to be done in a great haste, increasing the chances for mistakes and leading to a low quality of construction.

Boy, does that sound like the Soviet Union all over again. It also reminds me of how most government agencies operate in the U.S.
