The competition heats up: China has begun operational use of the world’s largest radio telescope, Five-hundred-metre Aperture Spherical Radio Telescope(FAST).
The radio telescope is similar to Arecibo Observatory in Puerto Rico. The dish is built into a natural depression in the ground and does not move.
On September 23, SpaceX released an update outlining the status of its investigation into the September 1 Falcon 9 launchpad explosion.
The report noted the following:
…the Falcon Support Building adjacent to the pad was unaffected, and per standard procedure was unoccupied at the time of the anomaly. The new liquid oxygen farm – e.g. the tanks and plumbing that hold our super-chilled liquid oxygen – was unaffected and remains in good working order. The RP-1 (kerosene) fuel farm was also largely unaffected. The pad’s control systems are also in relatively good condition.
While this report suggests they have made some progress, the fundamental cause of the explosion remains unknown.
For those who like to listen to the longer of my appearances I will be appearing on The Space Show on Tuesday at 7 pm (Pacific) for what is supposed to be a 90 minute interview, but which has never lasted less than 2 hours in the almost forty times I have been on the show. As always, it should be fun.
An evening pause: A very nice cover of the Tears for Fears song.

Cool image time! The image on the right, taken by Mars Reconnaissance Orbiter (MRO) and cropped from a wider view of a small crater and a small volcano caldera, certainly appears blurred and out of focus. Is MRO malfunctioning?
Nope. The blurring is actually an optical illusion caused almost entirely by our own assumptions of what a planet surface should look like combined with the alien processes occurring on Mars that have no equivalent here on Earth.
Below the fold is a wider view from the full image, showing the area of the cropped image to the right as well as the entire crater. Below that is another full resolution inset, this time showing the features on the crater rim that are sharp and stand out clearly. The blurriness of the rest of the image is not because the image is out-of-focus, but because a steady northwest-to- southeast wind has distorted everything in the same direction.

The Rosetta science team has released a detailed analysis of the jets and outbursts that they observed coming from Comet 67P/C-G during the comet’s close approach to the Sun.
Brief but powerful outbursts seen from Comet 67P/Churyumov–Gerasimenko during its most active period last year have been traced back to their origins on the surface.
In the three months centred around the comet’s closest approach to the Sun, on 13 August 2015, Rosetta’s cameras captured 34 outbursts. These violent events were over and above regular jets and flows of material seen streaming from the comet’s nucleus. The latter switch on and off with clockwork repeatability from one comet rotation to the next, synchronised with the rise and fall of the Sun’s illumination.
By contrast, outbursts are much brighter than the usual jets – sudden, brief, high-speed releases of dust. They are typically seen only in a single image, indicating that they have a lifetime shorter than interval between images – typically 5–30 minutes. A typical outburst is thought to release 60–260 tonnes of material in those few minutes.
They have also released a new image taken by the navigation camera of Rosetta’s September 30th landing zone.
Today it was revealed that Vulcan Aerospace, the company building Stratolaunch, is losing one of its top executives.
Aerospace veteran Chuck Beames is leaving his post as president of Microsoft co-founder Paul Allen’s spaceflight company, Vulcan Aerospace. Word of Beames’ departure came from Allen in an internal email that was sent to Vulcan employees and obtained by GeekWire today. Allen said Jean Floyd, the CEO of Vulcan’s Stratolaunch Systems, will expand his role to become Vulcan Aerospace’s interim executive director as well.
Allen’s email, which you can read in its entirety at the link, also called Orbital ATK “a valued partner.” The last we had heard of this partnership, however, was that Orbital ATK had backed out of it. Allen’s email instead suggests that some renegotiations are going on, and the partnership is not quite dead.
In order to replace a burnt capsule quickly in its Soyuz capsule, Russia will ignore its own safety rules and allow the engineers to work without draining the capsule of its propellants and gases.
Sources close to investigation told RussianSpaceWeb.com that a cable located behind the cosmonaut seats inside the Descent Module of the Vehicle No. 732 had accidentally been bent severely enough to damage its insulation. As it turned out, the problem had nothing to do with the encapsulation of the spacecraft inside its payload fairing on September 15, as was initially thought.
Replacing the damaged cable is relatively straight forward, but it now has to be conducted on the vehicle fully loaded with toxic propellants and pressurized gases. Such an attempt would violate usual safety rules, but draining the spacecraft off its propellants and gases would likely be even more unprecedented and require lengthy repairs.
The big issue here is not the willingness of Roscosmos management to break its safety rules. In fact, believe it or not, those rules are possibly too strict. The repairs are taking place inside the capsule where the astronauts sit. If it is too dangerous for engineers to be there with the capsule fueled, then it would be too dangerous for the astronauts. Granted, engineers don’t usually sign up for those kinds of dangers, but then, if you are an engineer in the field of rocket science I suspect you did sign up, and expect them.
No, what is significant about this story is the bent cable and its damaged insulation, which was bad enough that the cable actually burnt, based on other reports. It suggests a variety of issues in the construction of this capsule, all of which are worrisome. First and foremost, how is it possible for insulation to break simply by bending a cable? Is the insulation that badly made? Or have they such low tolerances for the insulation (possibly to save weight) that it requires a very careful installation that in this case was done badly?
This is also only the second launch of an upgraded Soyuz capsule. Could it be that they haven’t worked out all the kinks in its design? If not, they have been making Soyuz capsules for literally decades. One would think that the people that install this wiring would know its tolerances and not make such a mistake.
I know I am being somewhat harsh here, but that harshness comes after seeing repeated quality control problems in a variety of Russian-built aerospace hardware in recent years. In the previous cases, however, the problems did not involve a manned flight. This one did, and if those same quality control problems are now showing up with Soyuz, that is a very bad thing.

Just read it.
The coming dark age: A Bahrainii columnist was shocked to discover that within the Middle East there is a strong admiration by young people for Adolf Hitler.
The young girls’ admiration of Hitler’s personality and their inclination towards powerful [figures] led me to search for [material] on ‘Hitler adoration’ and fandom, and indeed, I discovered a wide spectrum of young Arabs who love Hitler. Some said they admired him for killing the Jews, but most were enchanted by his strength, determination, and steadfastness. This begs the question: What is behind these young peoples’ love of strength? Are they fans of the violence engulfing the region? Or does the sense of helplessness and weakness [cause them] to adore of a figure who challenged the world with his strength and led an entire people to fight the world?
We are facing a generation of young people who read [books], in an age when reading is considered obsolete – except that these [young people] read [material] of a very worrisome stripe, and acquire twisted values that could impact their future awareness, the extent of their control over things, and their situational assessments. The desire for acquiring and expressing power and for challenging the other has become a secret wish that steals into the hearts of these young people and which is expressed in many ways. This wish reflects the reality of a crisis-ridden, unstable society, [a reality whose expressions] range from suppression of free expression to the use of extreme violence on all levels – verbal, physical, and electronic [media violence].”
There are so many aspects of this story that are tragic and horrifying for the future that I myself do not know where to begin. The only saving grace that I can find is the intelligent and thoughtful horror expressed by the Arabian columnist herself, suggesting that within the Arab world there still remains some good will and a desire for civilization. Unfortunately, my sense is that she is part of a small minority who is losing ground steadily.
An evening pause: As the man says, “Dream big, work hard, be humble.”
