Musk tweets peek at Starship hopper
Capitalism in space: Elon Musk this week tweeted an image of the Starship test hopper, adding that they hope to begin test flights by March.
“This test hopper is at full body diameter of 9m / 30 ft, just not full height. Super Heavy will be full height & diameter,” Musk tweeted, indicating that the company will go directly to building a full-scale version of the rocket booster, rather than a truncated test version.
It seems to me that Musk continues to embarrass all other rocket companies, both private and governmental, with his effective use of current technology to innovate and produce new designs. While everyone else seems locked into building the same old things, his company is using what it knows to try to build something smarter and more efficient.
SpaceX’s track record suggests that it will do exactly what it is trying to do, even if it likely takes longer than they predict. Others should take heed, or they will all get left behind.
Japan quits global whaling regulatory body
Japan yesterday announced that it is quitting the International Whaling Commission, a global whaling regulatory body founded shortly after World War II to regulate commercial whaling that has instead in recent years attempted to ban all commercial whaling, except for favored native tribes in Russia and the Arctic.
The article’s last few paragraphs provide the real political background to this move by Japan:
An IWC-Japan divorce is the culmination of a wide ideological divide at the commission between ardent anti-whaling nations and countries seeking recognition of limited commercial whaling activities as legitimate. The anti-whaling forces have the upper hand, even though IWC’s expansion has seen more pro-whaling countries joining in recent years.
At the Brazil gathering, Japan had attempted to nudge the IWC toward reforms that would have potentially paved the way for a resumption of commercial whaling. The IWC was initially established to regulate whaling but has enforced an outright moratorium on commercial whaling operations since the 1980s in a desperate bid to prevent the extinction of several whale species. Many whale species have since recovered to a degree, but a few are still considered endangered.
Japan’s reform push was easily voted down. Instead, a majority of IWC members voted to have the commission turn its back on commercial whaling for good. That successful resolution also condemned Japan’s scientific whaling practices, widely regarded as a clandestine commercial operation as Japan’s whaling fleet takes hundreds of whales each year, with the meat ending up in grocery stores and restaurants.
IWC also approved subsistence whale hunts for Arctic aboriginal communities.
The large Japanese delegation at Brazil didn’t hide its frustration. The government accuses IWC members of hypocrisy for allowing culture exemptions from the moratorium for Alaskan and Russian native groups, but not for Japan and Scandinavian whaling cultures.
In other words, this commission has become increasingly political. Rather than focusing on protecting whale populations while allowing whaling by all parties, it has decided to pick and choose who can whale, and has decided to ban Japan while giving others the right to whale.
This political bias is not much different than what was seen at the Paris climate accords. Those agreements put odious restrictions on U.S. commercial activity, while putting no restrictions on China and others. It was this political bias, totally divorced from any sincere effort to reduce CO2 emissions, that prompted Trump to exit that agreement.
Gale Crater dunes: dry and volcanic in origin
Using data from orbit and from the rover Curiosity, scientists have determined that the material in the dunes in Gale Crater that Curiosity has visited are very dry and volcanic in origin.
This dryness is in contrast with the underlying ground, which shows evidence of water. The data also suggests that the material either came from multiple volcanic sources producing different compositions, or some of the sand was somehow changed at a later time.
In other words, the sand in the dunes came from elsewhere.
India aims for 24 launches in 2019
The new colonial movement: India has set a goal of two launches per month in 2019, a rate that would more than triple its previous high of seven.
Though the article does not specify, I suspect that a large percentage of these launches will be suborbital test flights. Nonetheless, this goal is ambitious, and indicates a serious commitment to advancing their space effort.
Russian Soyuz launches 28 satellites
A Russian Soyuz rocket today launched 28 satellites, the bulk of which were commercial smallsats.
The primary payload was two Russian Earth observations satellites.
The leaders in the 2018 launch race:
37 China
21 SpaceX
15 Russia
11 Europe (Arianespace)
8 ULA
This should close out Russia’s launch total for the year, that country’s lowest yearly total since the very beginnings of the space age in the 1960s.

Dried mud cracks on Mars?
Cool image time! The image to the right, cropped and rotated to post here, was one of the uncaptioned photographs in the December Mars Reconnaissance Orbiter (MRO) image release. If you click on the image you can see the entire photograph. I have cropped the most interesting area, though cracks can be seen in other areas in the image.
What we appear to have here is a darker lower valley filled with dried mud, which over time has cracked as it dried. At its edges there appear to be ripples, almost like one sees on the beach as waves wash the shore. The perimeter slopes even show darker streaks as if the water in some places lapped up the slopes, and in others flowed downward into the valley.
Later, several meteorite impacts occurred, the largest of which produced concentric dried cracks on its outside perimeter. This impact also provides a rough idea of the depth of the mud in this valley.
Mud of course suggests that this lower valley once was filled with water. Was it? It is not possible now to come to a firm conclusion, but this image’s location shown by the red dot in the overview map below and to the right, provides a clue that strengthens this hypothesis.

A Christmas Carol
As I have done in the past, to celebrate this Christmas day I give you the classic 1951 version of Charles Dickens’ A Christmas Carol, starring Alastair Sim It remains the best version, by far.
Dickens did not demand the modern version of charity, where it is imposed by governmental force on everyone. Instead, he was advocating the older wiser concept of western civilization, that charity begins at home, that we as individuals are obliged as humans to exercise good will and generosity to others, by choice.
It is always a matter of choice. And when we take that choice away from people, we destroy the good will that makes true charity possible.
China launches military satellite
The new colonial movement: China today used its Long March 3C rocket to launch a military communications satellite.
This was China’s 37th successful launch in 2018, only three launches less than their predicted 40 launches for the year. It almost doubles their previous record of 20 in 2016.

The real meaning of the Apollo 8 Earthrise image
Today is the fiftieth anniversary of the moment when the three astronauts on Apollo 8 witnessed their first Earthrise while in orbit around the Moon, and Bill Anders snapped the picture of that Earthrise that has been been called “the most influential environmental picture ever taken.”
The last few days have seen numerous articles celebrating this iconic image. While all have captured in varying degrees the significance and influence of that picture on human society on Earth, all have failed to depict this image as Bill Anders, the photographer, took it. He did not frame the shot, in his mind, with the horizon on the bottom of the frame, as it has been depicted repeatedly in practically every article about this image, since the day it was published back in 1968.
Instead, Anders saw himself as an spaceman in a capsule orbiting the waist of the Moon. He also saw the Earth as merely another space object, now appearing from behind the waist of that Moon. As a result, he framed the shot with the horizon to the right, with the Earth moving from right to left as it moved out from behind the Moon, as shown on the right.
His perspective was that of a spacefarer, an explorer of the universe that sees the planets around him as objects within that universe in which he floats.
When we here are on Earth frame the image with the horizon on the bottom, we immediately reveal our limited planet-bound perspective. We automatically see ourselves on a planet’s surface, watching another planet rise above the distant horizon line.
This difference in perspective is to me the real meaning of this picture. On one hand we see the perspective of the past. On the other we see the perspective the future, for as long a humanity can remain alive.
I prefer the future perspective, which is why I framed this image on the cover of Genesis: the Story of Apollo 8 the way Bill Anders took it. I prefer to align myself with that space-faring future.
And it was that space-faring future that spoke when they read from Genesis that evening. They had made the first human leap to another world, and they wished to describe and capture the majesty of that leap to the world. They succeeded beyond their wildest dreams.
Yet, they were also still mostly Earth-bound in mind, which is why Frank Borman’s concluding words during that Christmas eve telecast were so heartfelt. He was a spaceman in a delicate vehicle talking to his home of Earth, 240,000 miles away. “And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas, and God bless all of you — all of you on the good Earth.” They longed deeply to return, a wish that at that moment, in that vehicle, was quite reasonable.
Someday that desire to return to Earth will be gone. People will live and work and grow up in space, and see the Earth as Bill Anders saw it in his photograph fifty years ago.
And it is for that time that I long. It will be a future of majesty we can only imagine.
Merry Christmas to all, all of us still pinned down here on “the good Earth.”
SpaceX successfully launches GPS satellite
Capitalism in space: In launching an Air Force GPS satellite today, SpaceX successfully completed its 21st launch of 2018, the most ever achieved in a single year by a private company, ever, beating the record the company set last year by three.
The company has been so successful that many will take this achievement for granted. They should not.Ten years ago SpaceX barely existed. In that short time it has revolutionized the rocket industry, and recaptured for the U.S. the commercial market share that was lost by the older American rocket companies to Russia and Europe, because they were fearful and lazy and refused to compete.
The result however has not been zero sum. Launches in total have increased, and the potential for a revitalization of space exploration for everyone has not been as good since the 1960s. I know this will make some groan, but the sky now is literally the limit.
You can watch a replay of today’s SpaceX launch here.
The leaders in the 2018 launch race:
36 China
21 SpaceX
14 Russia
11 Europe (Arianespace)
8 ULA
China leads in the national rankings 36 to 34 over the U.S. At the moment only one more U.S. launch is scheduled, so it appears China will hold that lead. Stay tuned for my annual assessment of the launch industry, coming the first week in January.

Trump administration: parks to stay open to public during shutdown
Compare and contrast: Unlike the Obama administration, which went out of its way to inconvenience the public during government shutdowns, to an extent that it actually cost the government money, the Trump administration is leaving the national parks open to the public during the shutdown, even as it shuts visitor centers.
The link describes the National Park Service’s policy at Saguaro National Park here in Tucson, but this is apparently the policy nationwide:
“When you arrive at the park, both visitor centers will be closed. This is because due to the lapse of appropriation, we do not have money to pay for staff, so any facility that requires staff presence is going to be closed,” said Andy L. Fisher, a park ranger at Saguaro National Park.
That includes the contact station, the education building and programs, and ranger-guided walks and hikes.
“If you come out to one of the trail heads and plan on going for a hike, we’re not go to close the trail heads. We’re not going to chase you off the trails, the roads are going to continue to be open,” said Fisher.
This approach by the Trump administration is the morally correct one. The shutdown means they don’t have the money to run the government. It does not mean the parks can’t be accessed. They belong not to the government but to the American people. If there is no money to pay the government workers, that just means there will be no government workers at these parks. The parks themselves should remain open for public use.
OSIRIS-REx flies over Bennu’s north pole
Cool movie time! OSIRIS-REx has completed its first planned fly-over of Bennu, this time above its north pole, and the science team has released a short movie showing part of that fly-over. I have embedded the movie below the fold.
This series of MapCam images was taken over the course of about four hours and 19 minutes on Dec. 4, 2018, as OSIRIS-REx made its first pass over Bennu’s north pole. The images were captured as the spacecraft was inbound toward Bennu, shortly before its closest approach of the asteroid’s pole. As the asteroid rotates and grows larger in the field of view, the range to the center of Bennu shrinks from about 7.1 to 5.8 miles (11.4 to 9.3 km).
They have four more fly-overs of the asteroid’s poles and equator as they assemble a detailed map of its surface.

China launches first prototype of new low-cost communications constellation
The new colonial movement China today launched the first prototype Hongyun communications satellite.
Developed by the China Aerospace Science and Industry Corporation (CASIC), this is the fist satellite of a vast space-based communications network capable of covering every corner on the Earth, including the Arctic and Antarctica. The satellite mission is to verify low-orbit broadband communication technologies to be used on the Hongyun satellite constellation.
Announced by CASIC in September 2016, the Hongyun project has the goal of building a space-based communications network of 156 communications satellites into low Earth orbit, at an altitude of 160 to 2,000 km. Each satellite of the network will be able to transmit 500 megabytes of data per second. It will become operational in 2022.
These satellites, aimed at lowering cost, appear to be in direct competition with many of the new smallsat constellations being developed in the west by SpaceX, OneWeb, and others.
The leaders in the 2018 launch race:
36 China
20 SpaceX
14 Russia
11 Europe (Arianespace)
8 ULA
China has widened its lead over the U.S. in the national rankings, 36 to 33, and has likely now clinched that lead for the year. Stay tuned for my annual full report on the state of the launch industry in 2018.

New asteroid radar images
Cool radar images! The set of radar images above of near-Earth asteroid 2003 SD220 were created by combining radar data from three different radar telescopes on Earth, Arecibo in Puerto Rico, Green Bank in West Virginia, and Goldstone in California. As the press release notes:
The asteroid will fly safely past Earth on Saturday, Dec. 22, at a distance of about 1.8 million miles (2.9 million kilometers). This will be the asteroid’s closest approach in more than 400 years and the closest until 2070, when the asteroid will safely approach Earth slightly closer.
The radar images reveal an asteroid with a length of at least one mile (1.6 kilometers) and a shape similar to that of the exposed portion of a hippopotamus wading in a river.
The images have a resolution of 12 feet per pixel, so a close look should be able to reveal any large boulders, should they exist. Instead, I see a soft surface that to me resembles the surface of a sand dune, floating unattached to anything in space.
