Very brief descriptions, with appropriate links, of current or recent news items.
ULA has decided to delay the next Atlas 5 launch until early summer to give engineers time to inspect its entire stock of Russian first stage engines to make sure the problem that caused a premature engine shutdown during a March launch has been located and fixed.
Fascist brownshirts: A man tries to walk down the street in California wearing a Trump hat and gets physically attacked by anti-Trump protesters.
Nor is this all. The link describes numerous other examples of violence by anti-Trump protesters in California. This link describes additional anti-Trump violence, including smashing windows, destroying police cars, and attacking Trump supporters. More here.
I have posted a video below the fold of the man with the Trump hat being attacked.
As those who read my website know, I am not a fan of Donald Trump. However, I support fully the right of free speech for him and his supporters. Moreover, a close look at what he says shows that he isn’t a bigot nor is he racist. He has been very clear about his positions on immigration and Middle East refugees, and in neither case has he called for a ban based on race or religion. In the first case he has simply demanded that our immigration laws be enforced, and has justly criticized the federal government for failing to do its job. In the second case he has clearly said that this is not the time to accept large numbers of unvetted immigrants from the Middle East. While I do not trust him to do what he says, in neither case has he said anything that is that unreasonable.
These anti-Trump protesters however are not moved by mere disagreement. All that appears to move them is hate. They hate Trump and his supporters, see them as evil, and want them destroyed, by any means necessary. And if you don’t believe me watch the video below the fold.

More images from New Horizons reveal even more strange terrain on Pluto.
Data suggest that the bright rims are made of methane ice, while the dark crater floors are made of water ice, though why this has happened is a complete mystery. As they note at the link above, “Exactly why the bright methane ice settles on these crater rims and walls is a mystery; also puzzling is why this same effect doesn’t occur broadly across Pluto.”
ULA engineers have pinpointed the issue that caused a premature shutdown of the first stage Russian engine on the last Atlas 5 launch.
They are inspecting all of their Russian engines to make sure the problem will not repeat. Meanwhile, the next Atlas 5 launch has not yet been scheduled.
Embedded below the fold. Discussed the SpaceX proposal to send Dragon to Mars, as well as the ramifications of SpaceX’s first Air Force launch contract.

Good news: The Curiosity engineering team has found that the rough and fractured rocky terrain the rover has been recently traveling across on Naukluft Plateau has not significantly increased the wear & tear on the rover’s wheels.
The rover team closely monitors wear and tear on Curiosity’s six wheels. “We carefully inspect and trend the condition of the wheels,” said Steve Lee, Curiosity’s deputy project manager at NASA’s Jet Propulsion Laboratory, Pasadena, California. “Cracks and punctures have been gradually accumulating at the pace we anticipated, based on testing we performed at JPL. Given our longevity projections, I am confident these wheels will get us to the destinations on Mount Sharp that have been in our plans since before landing.”
Inspection of the wheels after crossing most of the Naukluft Plateau has indicated that, while the terrain presented challenges for navigation, driving across it did not accelerate damage to the wheels.
The uncertainty of science: New data from satellites have confirmed that the increase in carbon dioxide in the atmosphere in the past century is contributing to an expansion of plant life globally.
Researchers studying NASA satellite data on the Earth’s vegetation coverage have discovered that plants have significantly increased their leaf cover over the last 35 years to the point that new growth across the planet is equivalent to an area twice as large as the continental United States. According to the study, the largest contributor to this greening is the growing level of carbon dioxide (CO2) in the atmosphere.
Using data collected from instruments such as NASA’s Moderate Resolution Imaging Spectrometer mounted on the AquaProbe satellite and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer (such as that deployed on NOAA’s DSCOVR satellite), an international team of researchers has determined that CO2 fertilization explains fully 70 percent of the greening effect observed.
I love how the article repeatedly inserts several out-of-context comments about the dangers of global warming, even though everything in the story suggests that global warming might actually be beneficial.
The competition heats up: On April 27 the Air Force made it official and announced that SpaceX has won its first military contract, breaking ULA’s launch monopoly.
This contract award really isn’t a surprise, as SpaceX had been certified by the Air Force as a qualified bidder, and ULA had declined to bid on this particular contract, leaving SpaceX as the Air Force’s only possible contractor.
Update: The Air Force has admitted that SpaceX’s $83 million price is 40% less than what ULA has typically charged for a comparable launch, confirming what Elon Musk and SpaceX (and many others, including myself back in 2005) have claimed all along, that the Air Force’s EELV bulk buy (giving ULA an Air Force launch monopoly) was a bad idea, discouraging innovation, forcing costs up, and guaranteed to force the government to spend a lot of unnecessary extra money.
I must add that it is definitely worthwhile reading my UPI column from 2005 again, now, more than a decade later. I predicted quite accurately what has subsequently happened following the merger of Lockheed Martin and Boeing to form ULA.
The competition heats up: India has successfully launched its seventh home-built GPS satellite, completing their GPS constellation.
The seven first-generation satellites have been launched over a three-year period, starting with the deployment of IRNSS-1A in July 2013. ISRO has launched all of the satellites itself using the PSLV rocket. The flight number for Thursday’s launch was PSLV C33, which saw the vehicle fly in its most powerful configuration, the PSLV-XL. This version of the PSLV was introduced in October 2008 with the launch of the Chandrayaan-1 lunar probe, and features more powerful solid rocket boosters than the standard PSLV, increasing the amount of payload it can carry into orbit.
Meanwhile, they are gearing up for the first test flight of the engineering prototype of their reusuable spaceplane.
The competition heats up: After more than a decade of construction and more than $6 billion, the new Russian spaceport succeeded in its first rocket launch in the early morning hours of April 28, sending three satellites into Earth orbit.
Several news stories have said that Putin was not happy about the one day launch delay due to a computer issue, as well as the one day delay of a Soyuz launch in French Guiana earlier in the week.
Meanwhile, don’t expect any further launches at Vostochny for a long time. The spaceport really isn’t ready for regular operations. This launch was merely a face-saving gesture to disguise the fact that construction is really more than a year behind schedule, not three months.
The uncertainty of science: A new analysis of past data from Venus suggests that the planet’s atmospheric sulfur cannot be causing the atmosphere’s dark stripes seen in the ultraviolet.
If we look at Venus in a normal optical telescope, we see only a dull yellowish-white sphere without any other distinguishing features. However, if we capture an image in the ultraviolet range, the picture changes drastically – dark and light areas appear on the disc, reflecting the dynamics of the atmosphere. “These areas mean that somewhere in the upper cloud layer there is a substance that is absorbing UV radiation. Over the past 30 years there have been a wide range of hypotheses as to what this substance could be. Many scientists believed that sulfur particles were responsible for the absorption. But now we will have to abandon this hypothesis,” says Krasnopolsky.
It appears that the new analysis puts the sulfur too low in the atmosphere.
A reason to go to London: The world’s tallest tunnel slide, almost 600 feet long and 250 feet high, is being built as part of a sculpture that was part of the 2012 Olympic games location.
Once complete, the slide will be 178-m (584-ft) long and 76-m (249-ft) high, making it, according to the ArcelorMittal Orbit, the “world’s tallest and longest tunnel slide.” Riders will experience 12 twists and turns, including a tight corkscrew section called the “bettfeder,” which is German for “bedspring.” The slide ends with a 50-m (164-ft) straight stretch to the ground.
It is estimated that it will take about 40 seconds for people to descend the slide, with riders expected to hit speeds of up to 15 mph (24 km/h). On the way down, there will be dark sections, as well as points where it will be possible for riders to see out of transparent polycarbonate windows, providing brief views out over the Olympic Park and surrounding areas.
The competition heats up: Though no details have yet been released, SpaceX has announced through its twitter feed that they plan to send a Dragon to Mars by 2018.
This is not really a surprise, as rumors have been circulating literally for years of Musk’s Martian goals. Nor am I doubtful they can do it. What is important about this announcement is that it suggests that they are now confident that the delays for the first Falcon Heavy launch are mostly over, and that it will happen in the fall as presently planned. With this rocket they will have the launch capability to do a test flight to Mars.
The Curiosity science team has paused the rover’s journey up Mt Sharp in order to drill another hole, this time on the fractured rock covering the surface of Naukluft plateau.
The drill effort was a success, and they are now gathering data from the hole and the material from it. At the same time, the drilling process drained the rover’s batteries, which means they are now taking a break from science to let them recharge.
The first launch at Russia’s new Vostochny spaceport yesterday was aborted by its computers at T-1.5 minutes.
The head of Russia’s Roscosmos, Igor Komarov, said the launch was halted automatically due to the glitches of the automated control system. He said the system may be restored in a day. “As usual, the responsibility for what is happening in the space sector rests with those people who are in charge of it and head it,” Komarov added.
I love how governments and their minions always use the word “glitch” when the really haven’t the slightest idea what went wrong.
Regardless, based on their plans to try again tomorrow, I suspect that the problem was relatively simple, related to the computer sensing some parameter that was outside expected tolerances, and easily fixed.
At a conservative panel at the University of Massachusetts, Amherst, on Monday, protesters once again screamed and heckled the speakers, trying to silence them.
This was another event in the Milo Yiannopoulos speaking tour that saw the same kind of treatment on Saturday at American University. This time, Yiannopoulos was not alone, joined by Christina Hoff Sommers and Steven Crowder, who when he got the mike proceeded to give an epic 4 minute long put-down of the protesters, to loud applause from the audience. You can see some video of the event at the link above, but I have embedded Crowder’s rant below the fold, as it is absolutely worth seeing. He demonstrates the right way to treat these people, by standing up to them boldly, with humor, and courage.

My appearance on the Space Show yesterday is now available as a podcast. I strongly recommend people listen to it, especially the first hour. During that section I compared at length the cost and practicality of the Falcon Heavy with SLS/Orion, and noted how badly Congress and Presidents from both parties have served the American people these past twenty years in mismanaging our aerospace industry.
David Livingston called it a rant, and criticized me for it during the show, but I think the time has come for more Americans to rage in horror at the foolishness and possible corruption of our elected leaders in Washington.

The analysis is interesting and thoughtful, though some of the negative comments quoted from a former NASA engineer only illustrate why NASA was unable to do this very well. Moreover, these comments from Arianespace’s chief suggest that Arianespace doesn’t understand basic economics.
Arianespace Chief Executive Stephane Israel, in an April 23 briefing at Europe’s Guiana Space Center here on the northeast coast of South America, said Europe’s launch sector can only guess at how much SpaceX will need to spend to refurbish its Falcon 9 first stages. Israel said European assessments of reusability have concluded that, to reap the full cost benefits, a partially reusable rocket would need to launch 35-40 times per year to maintain a sizable production facility while introducing reused hardware into the manifest.
…Israel’s argument, which he has made before, is that even if first stages can be recovered and refurbished in a cost-effective way, the launch rate needed for maximum cost savings – and hence price reductions to customers – is beyond Europe’s reach. The only nations today whose governments are launching sufficiently often to reach those rates are the United States and China, and even these government markets may be insufficient, in and of themselves, to close the business case.
The customer base is not static. If you lower the price, the customer base grows, a fact that Elon Musk understands and which has been driving his effort from day one.
