A real report of Hillary’s first campaign stop

11:37 am

Forget the press. Forget the spin. Read this report by an ordinary college student of her attempt to participate, as an “Everyday Iowan”, in Hillary Clinton’s first presidential campaign event. With great pictures.

My point here is not to lambast Clinton (of which this event is the least of her problems). My point is to lambast the press. This campaign stop was not much different than the campaign stops and photo events of all politicians, staged and managed and completely divorced from reality. Sadly the press goes along and reports the staging. This report, created by an amateur, instead gives us the reality of the event, something that the press should be doing.

Instead, our mainstream press plays along with the politicians. They should be ashamed.

Ground-breaking for LSST takes place in Chile

3:12 pm

The official launch of construction of the Large Synoptic Survey Telescope (LSST) took place today in Chile.

Today, collaborators from the U.S. National Science Foundation (NSF), U.S. Department of Energy (DOE), Chile’s Ministry of Foreign Affairs and Comisión Nacional de Investigación Científica y Technológica (CONICYT) and several other international public-private partners will gather outside La Serena, Chile, for a traditional Chilean stone-laying ceremony to celebrate the construction launch of the Large Synoptic Survey Telescope (LSST).

They did the same kind of ceremony in Hawaii for the ground-breaking of the Thirty Meter Telescope, but things have gone very sour since. In Chile, however, I expect no problems. I wonder which local community has more sense.

New Horizons takes another picture of Pluto

2:28 pm

Pluto and Charon, April 9, 2015

Getting closer: The New Horizons science team has released the spacecraft’s first color image of Pluto and its moon Charon, taken on April 9.

The image is to the right. Right now Pluto is really not much more than a blob a few pixels across. However, images like this, taken in conjunction with later images, are useful to help refine the spacecraft’s course.

Another successful Dragon/Falcon 9 launch

1:16 pm

The competition heats up: SpaceX has successfully launched another Dragon freighter to ISS.

We await word on whether the first stage was able to successfully land vertically on a barge in the Atlantic.

Update: Musk reports that the first stage landed on the barge but “too hard for survival.” Expect some interesting video to follow. I have posted SpaceX’s video of the launch below the fold. Beginning at about 22:45, after first stage separation, you can see it maintain a vertical orientation as it begins its descent.

A detailed look at ULA’s proposed Vulcan rocket

8:54 am

Link here. Not only do they intend to recover and reuse the first stage engines, the rocket’s upper stage will be designed with the ability to be refueled and function as a space tug once it has reached orbit.

Ah, the joy of competition. It accomplishes so much, so quickly. I hope we never return to the feel-good era of “international cooperation.”

Stratolaunch update

8:48 am

This article about Paul Allen’s Stratolaunch company notes that the payload the system will put in orbit is likely to be less than originally hoped.

Still to be determined are the manned and cargo craft Stratolaunch will eventually send to orbit or even the International Space Station, Beames said. Musk’s SpaceX, an initial partner, is no longer associated with the venture. The rocket produced by Orbital ATK Inc., which replaced SpaceX, will probably be smaller than the medium-lift vehicle with a 6,000 kilogram (13,000-pound) payload that Stratolaunch had initially planned, Beames said. “I think it’s more likely we’ll be targeting a smaller payload class,” Beames said. “We’re not announcing anything on that yet.”

Allen’s company, Vulcan Aerospace, is also demanding that ULA change the name of its new Vulcan rocket, just revealed yesterday.

More evidence found for liquid water on Mars

8:39 am

A new study suggests that a liquid but very salty water does appear on Mars, during the night in the winter and spring months.

The team used Curiosity’s weather-monitoring equipment to look for those conditions and found that they occur every day in months throughout winter and spring. They suggest that overnight and before sunrise, some of the frost that forms on the planet’s surface interacts with the strong salts and turns liquid, seeping into the soil. This lines up with previous studies, which have detected geographic features that suggest flowing water.

The results come from the Gale Crater, which is itself too cold to support microbial life — even with liquid water present. But the study authors believe this phenomenon could occur anywhere on the planet, and may actually be more common in areas closer to the polar regions. Still, Mars is a pretty desolate place, and the amount of water we’re talking about is minimal at best. “There’s so little water that you can’t even see it visibly,” Morten Bo Madsen said.

ULA has dubbed its next generation rocket Vulcan

1:59 pm

ULA has announced its plans for replacing the Delta and Atlas 5 rockets, dubbing its new rocket Vulcan.

They plan to develop Vulcan’s first stage first and use it initially on Atlas 5 rockets so they can replace the Atlas 5 Russian engines as soon as possible. Also, they plan to recover the Vulcan rocket’s engines by having them separate from the booster after use and then get captured in a mid-air before hitting the ground. (See the graphic at the link to see a launch profile.)

In watching the press conference, ULA officials made it very clear that they are focusing a lot of their effort on lowering the cost of the rocket.

The distortion of the global surface temperature datasets

11:33 am

Link here. Goddard does a good job of illustrating the differences between the measured and reported climate temperature datasets, and how the reported numbers are consistently shifted to make the past cooler than measured and the present hotter than measured.

He often attributes this bias to dishonest tampering with the data to support the theory of global warming. He might be right, but it is important to remember that you shouldn’t necessarily assign malice to things that are just as easily explained by human error or stupidity. In this case he also notes that almost all the weather stations that have been decommissioned in the past few decades have been located in rural areas. To replace their data, global warming scientists average the data from nearby stations, most of which are in urban areas that exhibit warmer temperatures because city constructs tend to cause local warming. The result? The recent datasets tend to show a strong trend upward.

What is causing a cooling in the datasets from prior to 1970 however is not explained by mere error. The data hasn’t changed. Someone must be deciding to adjust it downward, for reasons that are simply not justifiable.

The skewed view of American inside the progressive bubble

10:10 am

Link here. The author captures well the cultural and intellectual chasm that exists between the modern American elite community, mostly leftwing, and the rest of American society. Sadly, that chasm is very clearly demonstrated by how most reporters are covering the emerging Presidential campaign. Read it and note the differences in how they approach both sides: They greet the Republicans with skepticism and scorn. They have private off-the-record dinners with Hillary Clinton.

Tracking the weather on an exoplanet

9:22 am

Scientists have begun gathering increasingly detailed information about the atmosphere and weather on the exoplanet HD189733B, 63 light years away with an orbit that produces a transit every 2.2 days.

It appears that the temperature rises with increasing altitude, reaching 3,000 degrees at the top of the atmosphere. There are also strong winds blowing from the cold to the hot side of the planet.

Dark energy evidence found to be uncertain

10:10 am

The uncertainty of science: Astronomers have discovered that the type of supernovae they have used as a standard to measure the accelerating expansion of the universe, which also is evidence for the existence of dark energy, are actually made up of two different types.

The authors conclude that some of the reported acceleration of the universe can be explained by color differences between the two groups of supernovae, leaving less acceleration than initially reported. This would, in turn, require less dark energy than currently assumed. “We’re proposing that our data suggest there might be less dark energy than textbook knowledge, but we can’t put a number on it,” Milne said. “Until our paper, the two populations of supernovae were treated as the same population. To get that final answer, you need to do all that work again, separately for the red and for the blue population.”

The authors pointed out that more data have to be collected before scientists can understand the impact on current measures of dark energy.

It has always bothered me that the evidence for dark energy was based entirely on measurements of type 1a supernovae from extremely far away and billions of years ago. Not only was that a different time in the universe’s history when conditions could be different, our actual understanding of those supernovae themselves is very tenuous. We really do not have a full understanding of what causes them, or how they even happen. To then assume that these distant explosions are all so similar that their brightness can be used as a “standard” seems untrustworthy. From my perspective, the conclusions, though interesting, are being pushed based on extremely weak data.

The research at the link illustrates just how weak that data was.

Hawaii governor extends halt to construction of telescope

9:18 am

Bowing to extortion: The governor of Hawaii has extended her stop order on the construction of the Thirty Meter Telescope at Mauna Kea because of the protests of about 30 people.

I am sorry, but I remain very skeptical about the real motives of most of these protesters. In every previous example, the reasons for the protests always vanished as soon as the protesters got a deal and some cash for their trouble. I suspect this is what is going to happen this time as well.

They aren’t protecting their “sacred site” on Mauna Kea. They are using the sacredness of the site to extort cash and favors from the state and the telescope operation.

New Horizons begins Pluto approach phase 2 of 3

11:41 pm

It’s getting closer! On April 5 New Horizons began the second of three approach phases in preparing for its July 14 fly-by of Pluto.

During this phase, which lasts until June 23, the spacecraft’s instruments will take the first ever color and spectral photos of the Pluto system. Observations taken during this period will provide sharper focus of Pluto and its five moons. Long exposure images will scan the region for additional moons and a possible ring system. Ultraviolet observation of both the surfaces and atmospheres of Pluto and Charon will begin during this phase.

The main goal of these observations, besides gazing at Pluto and its five moons, is to scan the region that the spacecraft will pass through, and make sure there is nothing there that might pose a threat.
