The Pentagon has denied ULA its request for a waiver to allow it to use more Russian engines in its Atlas 5 rocket than allowed by Congress.
It appears the Defense Department is in no hurry to give ULA any slack in its dependence on Russian engines, and instead seems to agree with Congress that the company should stop complaining and get around to replacing those engines as fast as possible.
A Hawaiian judge has ruled that the state’s emergency order that had forbid camping on the mountain was invalid.
The state says that it will still prohibit anyone from blocking the road, but I don’t know how they will be able to do that if a large number of protesters camp on the mountain, ready to move and block any construction vehicles trying to get to the mountaintop.
I think it is time for the makers of the Thirty Meter Telescope to consider a move out of Hawaii. I believe they will never be able to get the telescope built as planned.
The picture on the right will explain why I have been silent posting since Friday. I have just returned with five friends from three days of caving in New Mexico, doing some wild caving plus my first visit to Carlsbad Caverns since 1992, guided by a local caver who has been helping me with my cave survey project in Arizona.
New Mexico probably has the largest concentration of truly large and spectacularly decorated caves in the entire world. I’ve caved there previously, but this was my first trip driving from Arizona. We went to two wild caves, one of which I had never visited before and a second that I had seen during my 1992 trip. The picture shows me in the latter, standing above a large clear pool near the back of the cave with some giant flowstone speleothems all around me.
The new cave contained a room dubbed Speleogasm, because every formation there, of which there are too many to count, is completely festooned with helectites and sodastraws in a mad protrusion that no geologist can as yet explain. Nor is there any way to describe it adequately or photograph it successfully. To witness it you need to go, requiring the specialized caving skills that include the techniques and equipment required to rappel and climb a 40 foot rope.
As always, the advantages of learning how to do this successfully is the reward of seeing things that few ever see. It is why engineers and scientists strive so hard to get planetary probes to distant planets. And why humans want to travel to the planets. For me, getting inside a remote and beautifully decorated cave will just have to do.

The push to nominate Paul Ryan (R-Wisconsin) to run for the House Speaker position has apparently accelerated.
In all this, Ryan appears uninterested in running. My guess as to why is that he right now has a far more conservative reputation than he deserves, and becoming Speaker would reveal his moderate tendencies to everyone. He does not want this. At the same time, Ryan is more conservative than John Boehner, and would be an improvement.
Update: A Washington Post story today says that Ryan is reconsidering his opposition to running for Speaker.
The competition heats up: Blue Origins has revealed that the next test flight of its suborbital New Shepard capsule and launch rocket will take place before the end of 2015.
They also noted that they will not be selling any tickets for suborbital flights for at least two more years, until they are satisfied that the test flights have proven the system. This is a far cry from other suborbital companies like Virgin Galactic and XCOR, who have made big promises to garner ticket sales, and have yet to deliver. Jeff Bezos’s company has instead decided to deliver first, and then sell tickets.
In the end, we shall see who wins the race to put the first tourists into space. What is certain in all this however is that Virgin Galactic has squandered the ten-year headstart it had when it started out in 2004.
In related news, Virgin Galactic says that construction of its second SpaceShipTwo ship is progressing well.
Do you own red-blue 3-D glasses? Get them out and go to this link. Rosetta scientists have created a 3-D image of Comet 67P/C-G, including the jets of material shooting out from its surface.
[C]reating a 3d anaglyph of dynamic events like this is notoriously difficult: often the jets are too faint or their duration is too short to find two high-quality images taken several minutes apart that are suitable to pair together to create this type of view. However, the OSIRIS team got lucky with this particular event, capturing two images separated by about two-and-a-half minutes.
The image shows a bright, collimated jet embedded in a broader emission structure. The three dimensional perspective also reveals the conical shape of the jet and that the collimated feature is emitted towards the observer.
The Russian Luna-Glob has been delayed again, partly due to embargoes imposed by the Ukraine war, and partly due to a lack of money.
The article notes that Russia’s participation in the European ExoMars project has left little resources for this lunar mission, causing delays. It also notes the possibility that the second mission in ExoMars, scheduled for 2018, might be delayed as well. (The first ExoMars mission is scheduled to launch next year.)
All-in-all, this story indicates to me that the Russians continue to have serious underlying financial and management problems throughout their society. Having lost faith in capitalism, after 20 years of not really doing it right, they have returned to a soviet-style big government top-down approach. I doubt it will solve their problems.
Scientists studying the rounded rocks on the surface of the asteroid 25143 Itokawa, photographed by the Japanese probe Hayabusa, have concluded that sunlight combined with the asteroid’s tiny gravity caused them move and thus erode themselves.
As sunlight bounced off the orbiting boulders, photons provided a tiny push. As they radiated back outward as heat, they triggered a recoil effect that added a gentle spin. Over time, these slowly spinning boulders bumped into each other with enough force to wear their edges into smooth surfaces.
Warning! This is only a model, and thus could very well be wrong. It is reasonable however and worth considering as a factor in studying the early formation history of asteroids.
We’re here to help you! EPA workers have caused another wastewater spill in Colorado.
According to the Denver Post, an EPA mine crew working Thursday at the Standard Mine in the mountains near Crested Butte, triggered another spill of some 2,000 gallons of wastewater into a nearby mountain creek. Supporting Tipton’s remarks to Watchdog Arena, the Denver Post report states that the EPA had failed to release a report about the incident at the time of its writing.
Unlike the Gold King Mine, where on Aug. 5, an EPA mine crew exploring possible clean-up options, blew out a structural plug in the mine releasing over 3 million gallons of toxic waste into the Animas River, the Standard Mine is an EPA-designated superfund site, where the federal agency has been directing ongoing clean-up efforts.
According to a the Washington Times regarding this latest spill, Tipton’s spokesman, Josh Green, said that locals in the Crested Butte area confirmed the spill. Watchdog Arena spoke directly with Tipton Thursday afternoon who claimed, “They are reporting that the spill consisted of “gray water,” and was not toxic. But the definition of gray water does not preclude the presence of possible toxic substances.”
It doesn’t matter that this spill is smaller and at a superfund site. If a private landowner screwed up like this, and didn’t report it, as required by the EPA, the EPA would move in faster than the speed of light to take everything they owned and to put them in prison.
An evening pause: What this attempt achieves more than anything else is to demonstrate that the scale of the universe is almost impossible to simulate or to conceive. There is a lot of emptiness out there.
