Problems with nanosat launched from Vostochny

5:48 pm

Of the three satellites launched on the first liftoff from Russia’s Vostochny spaceport, the nanosat is having communication problems.

The problem with establishing a radio contact with the SamSat-218D nanosatellite is caused by its fast spinning, TASS the Samara State Aerospace University that designed the spacecraft told TASS on Wednesday. “When the spacecraft was placed into orbit, it started to spin round too quickly. It has a very little mass – less than two kilograms. As a result, its antenna cannot catch the information, the satellite is rotating rapidly,” the source said.

For Russia this nanosat is the first built entirely by college students, something that U.S. students have been doing for years.

New jellyfish spotted at 2 miles depth

2:04 pm

A NOAA mapping robot working two miles beneath the ocean surface recently captured video of a species of jellyfish previously unknown.

The newly discovered jellyfish has two sets of tentacles, short and long. When the the long tentacles are even and extended outward, and the bell is motionless, this could mean it’s readying to ambush its prey, scientists speculate. Inside the bell, red radial canals connect what scientists say looks like the bright yellow gonads.

I have posted the video below the fold.

Employers hiring freelancers to avoid Obamacare

10:19 am

Finding out what’s in it: A new study has found that almost three-quarters of all employers have decided to hire freelance workers rather than full-time employees in order to avoid the costs of Obamacare.

After surveying 600 human resource employees and 959 freelancers, the results show a whopping 68 percent of employers said the ACA will have a “high impact” on their hiring decision with 74 percent saying they plan to increase freelance contracts.

But don’t worry. Those evil conservatives who opposed Obamacare have been defeated. The next president, one of two liberal Democrats, will work to keep Obamacare, a law Democrats shoved down our throats, working

You asked for this

10:06 am

The post is short but this is the essence: “Given the choice between a dozen solid conservatives and one Clinton-supporting con artist and game-show host, you chose the con artist.”

Nothing can change the fact that all of Donald Trump’s past and recent history suggest that he is a moderate liberal Democrat. I expect him to rule in exactly that way should he win the presidency. He won’t be as corrupt or as leftwing as Clinton, but considering the power the federal government already wields, his willingness to support and use it will nonetheless contribute to the continuing decline in American freedom.

I hope I am wrong. I sadly do not expect that.

Eighth-grader arrested for using $2 bill

9:58 am

The coming dark age: School officials had an eighth-grader arrested when she tried to pay for her lunch with a legal $2 bill.

“I went to the lunch line, and they said my $2 bill was fake,” Danesiah told the news station. “They gave it to the police. Then they sent me to the police office. A police officer said I could be in big trouble.” School officials called Daneisha’s grandmother, Sharon Kay Joseph, and asked, ” ‘Did you give Danesiah a $2 bill for lunch?’ He told me it was fake,” the grandmother recalled.

An investigation into the $2 bill led Fort Bend ISD police to a local convenience store that gave it to Ms. Joseph, ABC reported. Police were then led to a bank where the 1953-issued bill was examined and determined to be real.

Note that both the school officials and the police had no idea that there is such a thing as a $2 bill.

Congressman proposes major changes to regulation of commercial space

9:46 am

Doug Messier has posted a detailed analysis of Congressman Jim Bridenstine’s (R-Oklahoma) proposed American Space Renaissance Act (ASRA) that is definitely worth reading.

Most of the changes appear aimed at organizing the regulation process of commercial space more completely under FAA control, rather than the hodge-podge of agencies that presently have responsibility. The bill also encourages NOAA and NASA to increase their use of commercial data for weather and Earth remote sensing.

At first glance, the bill looks good, but it also is not likely to be passed as written. Moreover, not surprisingly it calls for a hefty increase in funding for the FAA agencies being given more responsibilities, but I wonder if Congress will comparably reduce the funding of those agencies it takes responsibility from. My instinct tells me no, which means of course that the government and bureaucracy grows again.

SpaceX gears up for first Falcon Heavy flight

9:27 am

The competition heats up: SpaceX has already begun construction of one of the booster cores for its first test flight of Falcon Heavy, and expects to have all built by summer.

They have not yet decided on the payload or goal of that first test flight, though they appear to still be aiming for an November launch.

Meanwhile, they have a 1:21 am (eastern) Falcon 9 commercial launch tonight, in which they will also attempt another first stage barge landing.

Pluto’s solar wind interaction more like a planet’s

9:11 am

Data from New Horizons has found that Pluto, in its interaction with the solar wind, behaves more like a planet than a comet.

Previously, most researchers thought that Pluto was characterized more like a comet, which has a large region of gentle slowing of the solar wind, as opposed to the abrupt diversion solar wind encounters at a planet like Mars or Venus. Instead, like a car that’s part gas- and part battery-powered, Pluto is a hybrid, the researchers say. “This is an intermediate interaction, a completely new type. It’s not comet-like, and it’s not planet-like. It’s in-between,” McComas said. “We’ve now visited all nine of the classical planets and examined all their solar wind interactions, and we’ve never seen anything like this.”

…Pluto continues to confound. Since it’s so far from the sun – an average of about 5.9 billion kilometers (3.7 billion miles) – and because it’s so small, scientists thought Pluto’s gravity would not be strong enough to hold heavy ions in its extended atmosphere. But, “Pluto’s gravity clearly is enough to keep material sufficiently confined,” McComas said. Further, the scientists found that very little of Pluto’s atmosphere is comprised of neutral particles converted to electrically charged ions and swept out into space.

As I’ve written previously, we simply don’t know enough yet about planets to come up with a reasonable definition. As far as I’m concerned, Pluto will remain a planet until we do.

How tiny cowardice is destroying us

4:33 pm

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?

1:03 pm

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

12:10 pm

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

10:52 am

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

9:24 am

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

8:57 am

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

6:31 pm

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

6:01 pm

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…

Hat tip Edward Thelen.

Exoplanets found nearby

5:26 pm

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.
