How tiny cowardice is destroying us

Link here.

This is how culture wars are lost: through the slow accumulation of individually defensible but collectively unjustifiable decisions not to resist. It’s the decision that objecting during diversity training simply isn’t worth the hassle. It’s the decision not to say anything when you see a colleague or fellow student facing persecution because of their beliefs. It’s a life habit of always taking the path of least resistance, keeping your head down, and doing your best to preserve your own family and career. The small fights don’t matter anyway, right? I recently spoke to a mid-level executive at a major corporation who had been forced to sit through mandatory “inclusivity” training. The topic was transgender rights, and the trainer proceeded to spout far-left ideology as fact, going so far as to label all who disagreed with the notion that a man can become a woman “transphobic.” I asked if anyone objected to any part of the training, and the response was immediate. “Are you crazy? No one wants to deal with HR.”

Read it all. We are faced with bullies, who run away and hide the instant someone challenges them. The problem is that too many people are unwilling to challenge them, so they win time after time after time.

Ice and volcanoes on ancient Mars?

New data of past volcanic activity on Mars suggest that the red planet was once covered by at least one extensive ice sheet.

There is a great deal of uncertainty in this conclusion, however. They have found one example with the right geology to suggest past ice sheets under which volcanoes erupted. Translating this into an extensive ice sheet requires many assumptions that might not prove true with further research.

The Oil Seepage Thread

Because the comment thread to this post, “New research confirms CO2 increase is greening Earth,” has become quite long and somewhat off the original topic, yet still interesting and worth continuing, I have decided to create a specific post where comments relating to these two questions, asked by Wayne DeVette, can continue:

  • How much does Volcanic activity contribute to particulate & “greenhouse gas” emission’s on the Planet ? (I am under the impression contributions by human-activity are dwarfed by natural-events.)
  • What is the natural (non human-activity related) background seepage rate of crude-oil, into the Worlds oceans, across the Planet?

I thought these were great questions, and ask Wayne and others to do some digging. Gary and Wayne did, and what they found is worth reading.

Please place future comments on this topic here.

NASA signs engineering test agreement with new launch company

The competition heats up: NASA has signed an agreement to provide testing facilities to Generation Orbit so it can do test flights of its air-launched rocket.

Generation Orbit Launch Services, Inc. (GO) is pleased to announce the signing of a Space Act Agreement with NASA Armstrong Flight Research Center (AFRC) to collaboratively pursue the flight test and envelope clearance for the GOLauncher 1 air launched rocket vehicle. Utilizing AFRC’s experience and capabilities in flight test engineering for air launch rocket systems, the two year program will demonstrate integration of the GOLauncher 1 Inert Test Article (GO1-ITA) with NASA’s Gulfstream III research aircraft, captive carry flight testing, and release testing. Further, NASA AFRC will continue the development of its store separation analysis capability, eventually validating the toolset through release flight testing of the GO1-ITA.

Like many similar past SAA agreements, NASA will provide no money, but will make its facilities available for testing at no charge. For a new company like this, this availability will help them enormously, and is more in line with what NASA was originally designed to do.

ULA shuffles Atlas 5 schedule

ULA has rearranged the upcoming launch schedule of its Atlas 5 in the wake of its investigation of the valve issue that causes a premature shutdown of the first stage Russian engine during the Cygnus launch in March.

Originally they had intended to do three launches before the September 8 launch of NASA’s Osiris-REX asteroid mission. Now they will only do two, to give them additional time to test the rocket that will launch Osiris-REX.

August will be spent stacking an Atlas 5 rocket with a single solid booster, the 411 configuration, and rolling the vehicle to the pad for a rare countdown dress rehearsal to ensure systems are operating correctly ahead of the time-sensitive launch of NASA’s OSIRIS-REx probe to asteroid Bennu.

The spacecraft has a launch window that closes October 12.

Why Russian aerospace will not compete

The fallout from the scrub and one day delay of the first launch at Vostochny, while Vladimir Putin was there and watching, has generated an investigation and the suspension of one designer.

The official goal of the commission was to find causes of the failed launch attempt and to check the completeness of tests leading to the incident.

However given a minor technical impact of the delay, the investigation likely had the primarily political nature, namely it was aimed to demonstrate to the Kremlin that the industry problems were being dealt with. Moreover, Rogozin also made a decision during the work of the commission to suspend the responsibilities of Leonid Shalimov, the designer general at NPO Avtomatika, which supplied the hardware allegedly responsible for the incident. Rogozin summoned Shalimov to Moscow on May 6, apparently to present the results of the investigation. [emphasis mine]

When you develop any new system or cutting edge technology, things are certain to go wrong. This is the one certainty that I will admit to and gladly embrace, and to which good designers, scientists, and engineers all agree. Vostochny is brand new. It stands barely finished. No launch had ever been attempted there before. For there to be a one day delay because of a minor engineering issue is hardly a sign of poor workmanship. Instead, it suggests the people who built it did a reasonably good job, even as many of their managers ripped them and the project off.

What we see here is an industry that is being run not by people who understand the business, but by distant politicians whose only interest is power and control. Can you imagine any manager in Roscosmos anywhere being willing to approve the start of a radical new engineering project, faced with pressure from Putin and these power-hungry politicians in Moscow? It won’t happen. Until there is a change and the politicians let go of their control of this industry, Roscosmos is going to take the safe route every single time.

Nothing new is going to come from Russia’s aerospace industry for a very long time.

The doodles of a 7-year-old in 1300

Historians have uncovered the remarkable modern-looking doodles of a 7-year-old boy on bark paper used in Russian in the 13th century.

The sketches we are talking about hark back to circa 13th century AD, and they were made by a child named Onfim. It seems daydreaming and heroism-fueled reveries intervened with this 7-year old boy’s spelling lessons, so much so that he went on to draw himself as an imposing warrior with a sword and spear, after just writing the first eleven letters of his alphabet in the upper-right corner. And on closer inspection, one could also discern the horse upon which the ‘hero’ is mounted, along with the extended spear slaying his adversary – while the label of ‘Onfim’ makes the artist’s name clear.

But of course, the imagination of 7-year old Onfim was not just limited to portraying himself as a hero. At times he took the fantastical route to depict himself as a ‘wild beast’ (as made clear by another label proclaiming – ‘I am a wild beast’). The beast also seems to have a friendly attitude, as it carries a sign saying ‘Greetings from Onfim to Danilo’ – with Danilo possibly being Onfim’s schoolmate.

Take a look at the pictures at the link and tell me you haven’t seen these sketches on someone’s refrigerator recently.

Such Great Heights

An evening pause: Unfortunately, I have no idea who the performer is for this gentle and very beautiful cover of a song by The Postal Service. She does not identify herself on her youtube webpage.

They will see us waving from such great heights,
“Come down now,” they’ll say
But everything looks perfect from far away,
“Come down now,” but we’ll stay…

Exoplanets found nearby

Worlds without end: Astronomers have identified three planets close to the habitable zone on a star only 39 light years away.

A year on the two inner planets lasts just a couple of days. Data on the third world are sparse; it could take anywhere between 4.5 and 72.8 days to trek around its sun. The star, designated 2MASS J23062928−0502285, is roughly the size of Jupiter — about one-tenth as wide as our sun — and about 3,200 degrees Celsius cooler than the sun. Such runts make up about 15 percent of the stars in the galaxy, though astronomers had not found planets around one before. All three planets were discovered as periodic dips in starlight in late 2015 using TRAPPIST, a telescope at La Silla Observatory in Chile.

If anything does crawl or grow on these worlds, it bathes in mostly infrared light. The innermost planets receive several times as much energy from their star as Earth does from our sun, which technically puts them outside the star’s habitable zone (SN: 4/30/16, p. 36). But the planets are huddled up so close to the star that gravity might keep them from spinning, creating a temperate zone along the line where day turns to night, the researchers suggest.

Russia and Europe agree to delay next ExoMars mission

After looking at their schedules the Russians and Europeans have agreed that they cannot meet the schedule to launch the second ExoMars mission by the next launch window in 2018, and have agreed to delay the mission until 2020.

This really isn’t a surprise, since Russia was a late replacement of the U.S. when the Obama administration backed out of the project suddenly. They need time to prepare.

The depressed heart of Pluto

Using elevation data gathered by New Horizons during its fly-by of Pluto last year scientists have created an elevation map of the heart-shaped Sputnik Planum that shows that its central region is on average two miles deeper than the surrounding terrain.

The data even shows giant blocks of frozen water floating on the denser nitrogen ice.

Boiling water on Mars

Scientists now think that the dark streaks they see seasonally develop on Martian slopes are caused when frozen underground water brine is exposed to the atmosphere so that the water boils off, leaving the salt.

More here, including videos of their Earthbound experiments. On Earth, the boiling water caused avalanches and streaks, but because of the higher gravity they were not as long.

SpaceX updates its prices

The competition heats up: SpaceX this weekend updated the prices and listed capabilities for buying a Falcon 9 launch, while also adding the price and capabilities of its not-yet flown Falcon Heavy. Here’s the link to the SpaceX page.

The damage shakes out to $62 million for a Falcon 9 rocket launch with a payload of 4,020 kilograms (8,860 pounds) and $90 million for a ride on the much-anticipated Falcon Heavy rocket, set to debut in late 2016, which can ferry 13,600 kilograms (29,980 pounds) to Mars. In addition to adding an interplanetary destination to its wares, SpaceX has also upped the payload capacity of the Falcon 9 to low Earth orbit from 29,000 pounds to over 50,000 pounds.

The Falcon Heavy is expected to put slightly more than 50 tons into low Earth orbit, half of what a Saturn 5 could do, and about two thirds what the first version of SLS will be able to do. Yet, their price to buy a launch is actually less than what every other rocket company is charging for rockets approximately comparable to the Falcon 9 and about 500 times less than the cost to build that SLS rocket (what an SLS actually costs to launch is anybody’s guess, but it certainly ain’t anywhere near $100 million). And the upgrades on the Falcon 9 have also made it better than those other rockets because it can now put 25 tons into low Earth orbit, only slightly less than the space shuttle.

That they have added the Falcon Heavy is also more evidence that they are confident that its first test flight will be this year.

Russian court calls for arrest of Vostochny suspects

A Russian court has essentially done what we would call “denying bail” and demanded the arrest of two former Vostochny executives who have been charged with taking bribes during the construction phase of the spaceport.

The court ruled to arrest at least until June 20 the former chief of Spetsstroitekhnologii firm at the Federal Agency for Special Construction, Vladimir Shamailov, and his suspected accomplice Renat Syamiullin. The court agreed with the position in prosecution that staying out of prison the suspects could flee investigation as well as try to destroy the evidence. It is expected that today’s court ruling will be challenged.
