An avalanche pile on Mars

Avalanche pile on Mars

Cool image time! The Mars Odyssey science team has released this very interesting image, cropped on the right, of an avalanche debris pile formed when the large section of cliff on the left broke off and collapsed into the valley below. The valley is called Tiu Valles and is located close to Mars’ equator.

The wide spread of the debris is an indication of several things. For one, it illustrates the light Martian gravity, which allowed the debris to flow much farther than it would have on Earth.

For another, the spread of the debris pile suggests to me that the material that fell was very crumbly. It might have been able to hold together as a cliff for a long time, but when it collapsed the material broke apart almost like sand. Think of a sand castle you might have built as a kid on the beach. With a little moisture you can pack the sand to form solid shapes, but if your shape breaks apart the sand falls not as large blocks but as crumbly soft and loose sand. That is what appears to have happened here.

There is also the suggestion to me that water might have been involved somehow in this collapse. I am not a geologist so this speculation on my part is very unreliable. However, the shape of the debris pile suggests a liquid flow. The flow itself wasn’t liquid, but liquid might have somehow been involved in causing this geological event. We would need a geologist however to clarify these guesses on my part.

Orbital ATK aims for October 9-13 Antares launch

5:35 pm

Orbital ATK and NASA have now scheduled the first Antares/Cygnus launch since the rocket’s failure in October 2014 for no earlier than October 9.

Orbital ATK is targeting Oct. 9-13 for the launch of the company’s upgraded Antares 230 rocket. Liftoff will occur from the Mid-Atlantic Regional Spaceport to send the OA-5 Cygnus spacecraft, called S.S. Alan G. Poindexter, to the International Space Station (ISS). According to a news release from the company, a more specific date and time will be selected upon completion of final operational milestones and technical reviews. Launch times on these dates range from 10:47 p.m. EDT Oct. 9 to 9:30 p.m. EDT Oct. 13 (2:47 GMT Oct. 10 to 1:30 GMT Oct. 14).

Mars rover update: September 20, 2016

11:02 am

Opportunity comes first this time because it actually is more interesting.

Opportunity

For the overall context of Opportunity’s travels at Endeavour Crater, see this post, Opportunity’s future travels on Mars.

Having several choices on where to head, the Opportunity science team this week chose took what looks like the most daring route, heading almost due east towards the floor of Endeavour Crater. In fact, a review of their route and the images that the rover continues to take suggests that the panorama I created last week looked almost due east, not to the southeast as I had guessed. I have amended the most recent overhead traverse image, cropped and reduced below, to show what I now think that panorama was showing.

How cats conquered the world

8:47 am

Link here. This first large scale study of the DNA of ancient cat remains tracks how felines initially spread through human society in the ancient world.

The article and the researchers appear to make one mistake, however, in questioning whether cats have been domesticated. Anyone who owns a cat can answer that question unequivocally: No! Cats merely agree to live with us, on the condition that we treat them as they demand.

Update on wildfire at Vandenberg

8:34 am

Despite efforts to be rein it in, the wildfire at Vandenberg continues to burn and spread.

It has grown to include at least 5,000 acres.

The overhead image of the burn area at the link shows three launch sites. The SLC-3E site is ULA’s launchpad for the Atlas 5. The SLC-4E site is SpaceX’s launchpad at Vandenberg. The SLC-6 site was the site originally built for the space shuttle, never used, and has now been redesigned for ULA’s Delta rockets as well as payloads that need to be integrated vertically. For some close-up pictures, see my Vandenberg photo tour from 2015.

Manned Soyuz launch delayed until November

8:27 am

Roscosmos today confirmed that the short circuit discovered during prelaunch tests will delay the launch of a manned Soyuz to ISS until November.

Though they still have not described the problem in any detail, this article gives some insight:

According to industry sources, the delay was caused by a short circuit, which took place during roll-on of the payload fairing, which protects the spacecraft during its ascent through the atmosphere. The problem was not detected until the vehicle had been rotated back to a vertical position and was being prepared for the second fit check at Site 254 in Baikonur. The situation was complicated by the fact that engineers could not immediately identify the location of the short circuit in the fully assembled spacecraft. Preliminary estimates indicated that such an issue inside the descent module, SA, could require several weeks to fix, however if the problem was in the instrument module, PAO, it could take several months to resolve.

In worst case scenario, mission officials might decide to replace the Soyuz vehicle No. 732, which was affected by the problem, with Vehicle No. 733 originally intended for the Soyuz MS-03 mission. According to the official Russian media, the launch of the Soyuz MS-02 might be postponed until at least the beginning of October.

Putin to revive the KGB

9:22 pm

The coming dark age: One day after Putin’s party won an easy election victory it has announced that they plan on reviving the secret security force known previously as the KGB.

“The KGB was one of the strongest special services in the world – everyone recognised this,” Sergei Goncharov, who served in Russia’s now disbanded Alpha counter-terror unit in the 1990s, told state media. Mr Goncharov also said the creation of the MGB would provide Russia with a “strong fist” overseen by a unified leadership.

Kremlin critics were horrified by the possible rebirth of an organisation synonymous in Russia with political oppression. “It’s time to get out [of the country],” wrote Elshad Babaev, a Twitter user. “Anyone who can should take the opportunity.”

Unlike the 20th century, however, the west can no longer be called “the free world”, as it was then. Instead, we are lumbering toward the same evils, and thus do not necessarily provide a safe haven for real political refugees that we were then. Instead, our bankrupt intellectual leadership has been rushing to bring in fifth columnists from the Middle East while leaving the real refugees there to suffer persecution by Islamic radicals.

Senior Bush to vote for Clinton

9:11 pm

Why am I not surprised? Former President George H.W. Bush, the first Bush president, announced today that he plans to vote for Hillary Clinton for president.

Bush, 92, had intended to stay silent on the White House race between Clinton and Donald Trump, a sign in and of itself of his distaste for the GOP nominee. But his preference for the wife of his own successor, President Bill Clinton, nonetheless became known to a wider audience thanks to Kathleen Hartington Kennedy Townsend, the former Maryland lieutenant governor and daughter of the late Robert F. Kennedy. On Monday, Townsend posted a picture on her Facebook page shaking hands next to the former president and this caption: “The President told me he’s voting for Hillary!!”

All the Bushes have been closet Democrats since day one. All this does is confirm this fact for every Republican conservative nationwide. It will also allows Trump to cut them out of the power game should he win the presidency. I should also note that the Bushes are closely tied in with the congressional Republican leadership that has failed to fulfill any of their election promises since 2010, and have instead stabbed the voters who gave them a majority in the back, repeatedly. All this now becomes obvious.

India army suffers largest terrorist attack in decade

6:51 pm

Guess who: On Sunday seventeen India soldiers were killed by terrorists thought to come from a Islamic terror group based in Pakistan.

The Director General of Military Operations, Lieutenant General Ranbir Singh, said the terrorists were foreigners and there are clear signs of the role of the terror group Jaish-e-Mohammed, whose chief Masood Azhar is based in Pakistan. The group had been involved in the attack on Pathankot air base in January during which 7 army-men were killed.

An analysis of the situation can be read here.
