3D gun files still available to public despite judge’s ruling
Pushback: Despite a judge’s apparently unconstitutional ruling that banned the free give-away of the plans for printing 3D guns, the company that is producing them has instead made them available for purchase, at any price the buyer designates.
The ruling was intensely shaky and a jab to both the First and Second Amendment, so naturally Democrats were aroused.
But their celebration was premature.
Defense Distributed founder Cody Wilson crushed their short-lived happiness during a Tuesday press conference where he revealed that he actually won’t be stopped from sharing technical data; he will simply sell the files via his website, defcad.com. (Yes, he can do this.) “This judge’s order, stopping us from simply giving things away, was only an authorization that we could sell it, that we could mail it, that we could email it, that we could provide it by secure transfer. I will be doing all of those things, now,” announced Wilson.
“A lot of this to me was about principle,” he continued. “For many years, I just chose not to sell these files, because I’m an open-source activist. I believed in demonstrating that there was a right to commit this information to the public domain.”
“But, this is my opportunity to correct the media all in one place. To read headline after headline about how you can no longer 3D-print a gun, you can no longer have these files, this is not true. This has never been true. I now have to demonstrate this to you, forcefully, to deliver the point.”
There is no set price for the material; patrons are asked to give whatever they’d like in exchange. Wilson said the money would be used for further legal fees.
The judge’s ruling was completely bogus, especially since the Trump Justice Department had already settled the suit that the Obama Justice Department had brought. Moreover, since when can a judge ban the publication of any information the U.S.? His ruling appears to violate the First Amendment, and possibly the Second Amendment as well.
The search for Mars Polar Lander
In December 1999 the U.S. lander Mars Polar Lander was to set down near the southern polar cap of Mars. After an almost routine eleven month journey to Mars, all efforts to contact the spacecraft after its landing failed. A NASA review eventually concluded that the spacecraft had prematurely shut down its landing engines while the spacecraft was still far above the surface, and had therefore crashed to the ground.
Since then there have been extensive efforts to locate the lander’s remains on the surface, all to no avail. Though Mars Global Surveyor, in orbit at the time, tried to find it, its resolution was not sufficient. In recent years Mars Reconnaissance Orbiter (MRO) has taken several dozen high resolution images of the estimated landing area, two of the most recent were included in the August 2018 image release. The image on the right is a cropped section of one of those images, illustrating the difficulty of the search. (If you click on the image you can explore the full version.) The other image is quite similar.
As the southern polar cap shrinks and grows seasonally, it produces endless numbers of black spots from the release of underground dust as the carbon dioxide dry ice sublimates into gas. Moreover, the growth and retreat of the dry ice cap changes the landscape, periodically covering any remains of the rover as well as quickly removing many of the ground disturbances that the crash might have caused. In the almost two decades since the lander’s crash landing, about ten Martian years have passed, meaning that cap has melted and frozen ten times over this region in that time.
The image on the right shows the footprint of all the images that MRO has so far taken of the Mars Polar Lander landing area. If you are ambitious and want to get your name in the news, all you have to do is spend some time combing through those images and find the lander there. Every one of these images is available for public download at full resolution. Go to HiRise image archive, hover your mouse over latitude 77 degrees south, longitude 166 degrees east, and click several times to zoom in. You then change the selector icon at the top from “+” to “the arrow”. When next you click on any portion of that footprint it will show you a bunch of the images taken, all of which you can now download and inspect.
If you are successful and find the lander, please let me know. It would be nice to make that announcement here on Behind the Black.
Arecibo gets upgrade, new funding
Back from the dead: Threatened with closure only last year due to lack of funds, then damaged badly from Hurricane Maria, the Arecibo radio telescope in Puerto Rico has not only obtained a new operational funding from a new partner but also a $6 million upgrade.
The money will help design and build a super-sensitive set of antennas to be installed at the focal point of Arecibo’s dish. The 166 antennas, together part of the phased-array feed to be installed in 2022, are expected to significantly increase Arecibo’s capabilities. The phased-array feed will boost the telescope’s sky survey speed, making it five to six times faster than it is now, and it’ll enable the telescope to look at a larger piece of sky at one time.
…This month’s announced upgrade comes after years of uncertainty about Arecibo’s operations. In September 2017 Hurricane Maria caused about $14 million in damage to the telescope and ancillary buildings, some of which is still being repaired today. The facility lost its 430-megahertz line feed, which was used for atmospheric studies. Pieces of the antenna fell and punctured panels in the primary reflector of the main dish, forcing the replacement of 80–90 of the panels. There was also significant flooding under the primary reflector, which damaged some of the lines and heating facilities. In addition, several pieces of electronic equipment, some imagers, and laser rangers were damaged. Three buildings — a maintenance facility, a heater/transmitter building and a family unit — were also partially or completely destroyed due to rock and tree debris.
The hurricane was only the latest challenge for the observatory, after Arecibo had fought off repeated threats of closure over the previous decade due to NSF funding concerns. The latest situation was resolved last February, when a consortium led by the University of Central Florida took over operation and management of the observatory, significantly lessening the burden on NSF.
While Arecibo is no longer the world’s largest single radio dish, having been topped by China’s FAST radio telescope, it appears at least for now better positioned to do research. China does not yet have the radio astronomers experienced enough to operate its telescope, and so FAST at present is significantly under-utilized.
Hayabusa-1 sample pins down age of asteroid
Using particles gathered by Hayabusa-1 Japanese scientists have determined the age of the asteroid Itokawa.
Japanese scientists, including those from Osaka University, closely examined particles collected from the asteroid Itokawa by the spacecraft Hayabusa, finding that the parent body of Itokawa was formed about 4.6 billion years ago when the solar system was born and that it was destroyed by a collision with another asteroid about 1.5 billion years ago.
These results are only the beginning. As more samples return from more asteroids, scientists will start to add details to the overall history of the formation and evolution of the solar system, adding significant depth to the rough outline they presently have. And these new samples are already on the way, with both Hayabusa-2 and OSIRIS-REx approaching their target asteroids.

Inexplicable high latitude Martian terrain
Strange image time! The image on the right, reduced in resolution to post here, comes from the August 1, 2018 image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO). (If you click on the image you can see the full resolution version.) I have not cropped this image at all, so that you can see all of its swirling terrain.
This image did not come with a caption. The image site merely describes this terrain as having an “interesting morphology.” The location, in the very high southern latitudes (78 degrees south) just outside the southern rim of a very large crater, provides a slight explanation, as the growth and retreat of the Martian carbon dioxide polar caps is known to create very strange landforms. These swirling flows are obviously an example of one such landform.
The crater rim is just off of the top of the image and parallel with it. Therefore, the apparent erosional flows going around the hills and mesas are running parallel to the rim, not down from it. The black specks scattered about are probably points where dust was released as the carbon dioxide turned from ice to gas, a process that at the high latitudes on Mars often causes what planetary scientists call “spiders.”
I will not even try to make a guess at the process that formed what we see here. The image itself was taken on June 16, 2018 as part of a seasonal monitoring effort, which means scientists expect there to be changes occurring here from year to year as the polar cap shrinks and grown. An almost identical image had been taken two years ago, on December 18, 2016, and shows almost no black specks, probably because of the different time in the Martian year. A much closer comparison of both high resolution images would be necessary to tease out any more subtle changes.
EXOS completes successful test flight of reusable suborbital rocket
Capitalism in space: EXOS Aerospace yesterday completed a successful test flight of its reusable suborbital rocket, SARGE, at Spaceport America in New Mexico.
The company’s first Suborbital Autonomous Rocket with GuidancE, or SARGE, rocket lifted off from Spaceport America in New Mexico at approximately 2:15 p.m. Eastern. After reaching an unspecified peak altitude, the rocket descended under parachute, landing about 15 minutes later a short distance from the pad. The rocket’s nose cone, descending under a ballute, landed several minutes earlier.
The company didn’t immediately disclose technical details about the flight, such as the peak altitude, but in a live webcast of the launch appeared to be satisfied with the vehicle’s performance, despite the vehicle appearing to veer from its vertical trajectory briefly after liftoff.
“This was a very successful test for us,” said John Quinn, chief operating officer of Exos, on the webcast. “We’re very excited that we had all of our recovery systems operational.”
It sounds as if they were mostly testing the recovery systems that will allow the rocket and payload to land safely in a condition to fly again.

OSIRIS-REx takes first image of Bennu
OSIRIS-REx has taken its first images of Bennu from a distance of 1.4 million miles.
The images are not much to look at, showing a mere dot moving across a star field. Nonetheless, they show that the spacecraft’s camera is working, and that it is on course for its December 3rd arrival.
