Jury rejects lawsuit by disgruntled former SpaceX employee
A jury has ruled in favor of SpaceX and against a former employee who claimed he was fired because he complained about management and testing policies at the company.
Though it is hard to say what really happened, it does appear that, once given all the evidence, the jury agreed with SpaceX that the former employee was fired for good cause.
Using math to protect the Washington power structure
What could possible go wrong? A group of mathematicians have written software designed to prevent the gerrymandering of congressional districts, and are offering that software as a weapon for the courts to force states to revise the districts, even though those districts were created by fairly elected state legislatures.
Leaning back in his chair, Jonathan Mattingly swings his legs up onto his desk, presses a key on his laptop and changes the results of the 2012 elections in North Carolina. On the screen, flickering lines and dots outline a map of the state’s 13 congressional districts, each of which chooses one person to send to the US House of Representatives. By tweaking the borders of those election districts, but not changing a single vote, Mattingly’s maps show candidates from the Democratic Party winning six, seven or even eight seats in the race. In reality, they won only four — despite earning a majority of votes overall.
Mattingly’s election simulations can’t rewrite history, but he hopes they will help to support democracy in the future — in his state and the nation as a whole. The mathematician, at Duke University in Durham, North Carolina, has designed an algorithm that pumps out random alternative versions of the state’s election maps — he’s created more than 24,000 so far — as part of an attempt to quantify the extent and impact of gerrymandering: when voting districts are drawn to favour or disfavour certain candidates or political parties.
There are numerous problems here, all of which center on my basic disbelief in the non-partisan objectivity of these scientists and their work.
First, note the first example used. Mattingly proudly shows how his software demonstrates that Democrats could have won more districts in North Carolina. In fact, if you read the article, he claims that the district revisions produced by his software (producing more victorious Democrats) creates fairer districts than the districts created by the state’s fairly elected Republican legislature. Moreover, it was the Republican redistricting that prompted this mathematician to write the software.
Funny how he never felt compelled to do this when it was Democrats controlling the legislatures and gerrymandering the congressional districts to their benefit.
Second, he has offered this software to the courts as evidence to overrule the redistricting done by fairly elected legislatures. In other words, this software will be used to justify letting unelected experts decide how congressional districts should be shaped, not elected officials picked by voters.
Third, note who has expressed interest in using this mathematician as a witness to win its lawsuits:

Luxembourg revises space law to address Outer Space Treaty
Luxembourg has revised its proposed new space law in order to try to address the property right concerns posed by the Outer Space Treaty.
The legislation is patterned on the U.S. Commercial Space Launch Competitiveness Act of 2015, which includes provisions that grant U.S. companies the rights to resources they extract from asteroids or other celestial bodies. One difference, Schneider said, will be that while the U.S. law requires companies to be based in the country, Luxembourg’s protections would cover companies regardless of their location. “We don’t really care where the money comes from,” he said.
The bill also creates a system for the authorization and continuing supervision of commercial space activities that are regulated by the country. The lack of similar policy in the United States for “non-traditional” commercial space activities like asteroid mining — required, many argue, in order to comply with Article 6 of the Outer Space Treaty — has been an issue debated in the last few years.
…Luxembourg is also in the process of creating a national space agency, Schneider said. The country is a member of the European Space Agency but has not previously had its own national agency. However, he said the agency will be structured differently than those in other countries. “This space agency will not be a copy of NASA or ESA, but it will be a space agency whose only focus on the commercial use of space resources,” he said. It will be set up a public-private partnership between the government and private funds.
I would say that the competition in space is definitely now heating up. These actions by Luxembourg might not solve the legal problems with the Outer Space Treaty, but they will certainly up the pressure on the world’s space-faring nations to face the issue.
At the rim
On a lark, last week I called Xanterra, the vendor that runs the hotels on the south rim of the Grand Canyon, to see if they had any rooms available anytime during the summer. Diane and I wanted to do a day hike down the Hermit Trail, and to do it we needed to stay at a hotel the night before and the night after.
To my surprise, they had a rim view room available in Bright Angel Lodge, for tonight and tomorrow. The picture on the right is taken from our room, right after we arrived earlier today. I am right now sitting at that window, watching the sun set on the canyon buttes even as I type. Yowza!
I will post more tonight, and some tomorrow night as well. I will also do my podcast with John Batchelor tomorrow, live, from this room. Most cool, I must say.
Simon & Garfunkel – The Sounds Of Silence
An evening pause: From a recent live performance. I’ve posted this song before, sung by others, but not surprisingly, the best version is still performed by the originals.
I also think of this verse today whenever I read of the insane craziness going on in the political world:
And in the naked light I saw
Ten thousand people, maybe more
People talking without speaking
People hearing without listening
People writing songs that voices never share
No one dared
Disturb the sound of silence

T Rex fossils suggest it was covered with scales, not feathers
The uncertainty of science: The only known fossils of a T Rex’s skin suggest that the dinosaur was covered with scales, not feathers as recent research has theorized.
[I]f these large tyrannosaurs had any feathers at all, says the team, their fluff would have been limited to their backs—the only body part for which they were lacking fossil impressions. Because their earlier cousins did have feathers, it’s likely that the large tyrannosaurs lost them somewhere along the way, the team suggests.
Astronomers confirm that comet caused Wow! signal, not aliens
Astronomers have confirmed that the Wow! signal, thought to be the most promising detection by SETI of alien life, was actually caused by a comet.
Last year, a group of researchers from the Center of Planetary Science proposed a new hypothesis that argued a comet might be the culprit. The frequency could be caused by the hydrogen cloud they carry, and the fact that they move accounts for why it seemingly disappeared. Two comets, named 266/P Christensen and P/2008 Y2 (Gibbs), happened to be transiting through that region of space when the Wow! signal was detected, but they weren’t discovered until after 2006.
To test the hypothesis, the team made 200 radio spectrum observations between November 2016 and February 2017. Sure enough, 266/P Christensen was found to emit radio waves at a frequency of 1,420 MHz, and to double check, the researchers moved their radio telescope by one degree. As expected, the signal vanished, and only returned when the telescope was trained back on the comet.
This story demonstrates once again why, in science, it is very dangerous to jump to any conclusions. The data we receive is a mystery. We must keep an open mind to solve that mystery.
China reveals landing site for Chang’e-5 lander/rover
China has chosen the landing site for its Chang’e-5 lander/rover and sample return mission, planned to launch later this year.
Liu Jizhong, director of China Lunar Exploration and Space Engineering Center of China National Space Administration (CNSA), for the first time disclosed the probe landing site, an isolated volcanic formation located in the northwest part of the Moon’s near side.
They also said their focus will be the Moon’s south pole, where there is evidence of the possible presence of water ice.
