Chuck Jones on Getting Started
An evening pause: “It costs money to die poor.”
For those who don’t know, Chuck Jones directed some of the best Bugs Bunny cartoons that Warner Brothers ever produced.

Saudi Arabia has launched a military strike against Yemen
Saudi Arabia has launched a military strike against Yemen’s defense ministry.
It wasn’t immediately clear if the attacks were air or missile strikes, but they came following reports that Iran had manufactured the ballistic missile fired by Yemen’s Shiite rebels toward the Saudi capital a week ago.
Remnants of the missile bore “Iranian markings,” the top US Air Force official in the Mideast said Friday, backing the kingdom’s earlier allegations.
This isn’t that much of a surprise, considering the recent purge in Saudi Arabia as well as the recent reports of both Saudi Arabia and Kuwait warning their citizens to leave Lebanon. The military strike today in Yemen appears to therefore merely be a precursor of a more significant escalation.
A storm on Jupiter
Cool image time! The image above, reduced in resolution to post here, was taken during Juno’s ninth close fly-by of Jupiter in late October, and shows one particular storm swirl in the gas giant’s southern hemisphere.
The Juno team today highlighted an image taken during this fly-by of Jupiter’s entire southern hemisphere, but I find this close-up more interesting. Be sure to check out the full resolution version. It appears to me that the white swirls have risen up above the gold and blue regions, casting shadows down upon them.
Unfortunately, I cannot tell you the scale of this storm, as the release does not give any details, including where in the full hemisphere image it is located. I suspect, however, that it is large enough to likely cover the Earth.
Both the full hemisphere image and the image above were processed by citizen scientists Gerald Eichstädt and Seán Doran.
Physicists shrink their next big accelerator
Because of high costs and a refocus in research goals, physicists have reduced the size of their proposed next big particle accelerator, which they hope will be built in Japan.
On 7 November, the International Committee for Future Accelerators (ICFA), which oversees work on the ILC, endorsed halving the machine’s planned energy from 500 to 250 gigaelectronvolts (GeV), and shortening its proposed 33.5-kilometre-long tunnel by as much as 13 kilometres. The scaled-down version would have to forego some of its planned research such as studies of the ‘top’ flavour of quark, which is produced only at higher energies.
Instead, the collider would focus on studying the particle that endows all others with mass — the Higgs boson, which was detected in 2012 by the Large Hadron Collider (LHC) at CERN, Europe’s particle-physics lab near Geneva, Switzerland.
Part of the reason for these changes is that the Large Hadron Collider has not discovered any new particles, other than the Higgs Boson. The cost to discover any remaining theorized particles was judged as simply too high. Better to focus on studying the Higgs Boson itself.
United Arab Emirates signs space agreement with Germany
The new colonial movement: The United Arab Emirates (UAE) has signed a memorandum of understanding with the German Aerospace Center.
The press release doesn’t say much, other than the agreement will facilitate the exchange of information. Since the UAE can contribute little here but money, and none appears to be offered, I am curious as to exactly what is involved. It could be that Germany is looking at this as a form of inexpensive foreign aid, providing help to the UAE’s nascent space effort in order to establish good will and good relations.
Update on the development of Blue Origin’s orbital rocket New Glenn
Link here. The article provides a lot of interesting details about Blue Origin’s plans and status, including this tidbit about the New Glenn assembly facility, now expected to be finished by February 2018 at the latest:
The facility will largely be used to build the second and third stages for New Glenn, with Blue Origin actually planning to construct very few first stage boosters.
With each first stage booster planned to be reused up to 100 times, the factory will mainly concentrate on – and for large periods of time is only planned to – produce 2nd and 3rd stages. Mr. Henderson noted that once the first stage boosters are retrieved after flight, their storage will be managed across the refurbishment facility at LC-36 (capable of holding three or four boosters), the integration facility at LC-36 (also capable of holding “at least” three or four boosters), and the Merritt Island production facility (which can hold four boosters).
This would seemingly reveal that Blue Origin plans to rely on roughly only 12 first stage boosters at a time (once New Glenn is fully operational and recovery is “routine”), relying almost exclusively on booster recovery and refurbishment to maintain its first stage boosters manifest.
The article also notes the Blue Origin intends to always land its stages on a barge, and is about to finalize the purchase of that barge.
What I am puzzled about is the almost complete disappearance from the news of the company’s suborbital project, New Shepard. The last news story I’ve seen, from mid-September, said they hoped to resume test flights before the end of the year, with manned flights in 2018. Since then, however, there has been no updates, which makes me wonder if Blue Origin has decided to put that suborbital tourism project aside.
Crowdfunding campaign to honor only cat to fly in space
A crowdfunding campaign has been started to build a 5-foot-tall bronze statue in honor of Félicette, the only cat to fly in space.
While the first dog in space, Laika, has a statue, and the first chimp, Ham, has a memorial, Félicette has close to nothing. There are some commemorative stamps honoring a mythical space cat “Felix.” But Felix’s portrait doesn’t look like Félicette and it has a male name, so this is not enough for Guy. If anything, he says, the stamps simply help erase the existence of female astronauts.
The French space program gathered 14 cats, implanted electrodes into their brains, and put them through training similar to the way that they train human astronauts. They ultimately chose Félicette to make the trip, either because of her docile personality, or because she had not put on too much weight, according to differing accounts.
She was launched into space from Algeria [in 1963], and made it nearly 100 miles above Earth. For five minutes, she was weightless. Félicette came back to Earth unharmed, parachuting down and being retrieved only 13 minutes after having left her home planet. She stayed at the program’s lab for two to three months, according to Guy, but scientists later killed her to study the effects of space travel on her body.
Seems to me to be the right thing to do.
XCOR files for bankruptcy
Capitalism in space: Unable to find new investors, XCOR Aerospace filed for bankruptcy earlier this week, beginning the process that will liquidate the company.
Freedom and competition produce wealth and success better than any other approach, but they also allow for risk and failure. Sadly, XCOR has now demonstrated this downside.

Washington swamp creature hints that SLS could be in trouble
Congressman Lamar Smith (R-Texas) today expressed strong disappointment with the repeated delays in the the launch of SLS and Orion, noting that the problems could lead to Congress considering “other options.”
“After all these years, after billions of dollars spent, we are facing more delays and cost overruns,” Smith said. While he noted that some delays were caused by factors out of NASA’s control, like a tornado that damaged the Michoud Assembly Facility in New Orleans in February, “many of the problems are self-inflicted.”
“It is very disappointing to hear about delays caused by poor execution, when the U.S. taxpayer has invested so much in these programs,” he added.
Smith, who announced Nov. 2 he would not run for reelection next year after more than three decades in the House, including serving as chairman of the science committee since 2013, warned about eroding support for the programs should there be additional delays. “NASA and the contractors should not assume future delays and cost overruns will have no consequences,” he said. “If delays continue, if costs rise, and if foreseeable technical challenges arise, no one should assume the U.S. taxpayers or their representatives will tolerate this forever.”
“The more setbacks SLS and Orion face, the more support builds for other options,” he said, not elaborating on what those options would be.
Smith is part of the establishment in Congress that has been supporting SLS and Orion blindly for years. Unfortunately, he is retiring this year, and the other members of his committee did not seem as bothered by SLS’s endless delays.
