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.
Apollo 8: Fifty years ago
Fifty years ago the Apollo 8 mission successfully began with a 6:51 am launch at what was then called Cape Kennedy. It would be a space mission that would not only make history, being the first to take humans to another world, it would change America and western culture in ways no one at that time imagined.
I don’t have much to add. I’ve written hundreds of thousands of words on this mission already. If you want to know more, you can read or listen to Genesis: the Story of Apollo 8.
What I find gratifying is that it appears my goal in writing the book in 1998 has been an unparalleled success. Today alone there have been three major stories celebrating Apollo 8 and its legacy, from the Washington Post, Scientific American, and New Atlas. In the past week there have another half dozen. I expect dozens more in the coming week. All so far have gotten their facts right, and have been able to tell the story correctly of this nerve-racking mission given 50-50 odds of success. More important, all have understood thoroughly the political and historical context of the mission, and the long term impact that it had.
In 1998, when I wrote Genesis, the mission had been largely forgotten, even though I knew and remembered how important it had been. When the book came out that year, during its thirtieth anniversary, I was pretty much the only one writing about it, expressing my strong desire to change this lack of recognition, to make people remember.
Today, none of the many articles about Apollo 8 make mention of my work. This is right and fitting. I wasn’t an astronaut on board. Nor did I build the rocket or capsule. I was merely a historian telling the story. However, if my poor effort has served to make others remember, and report the story correctly in 2018, its fiftieth anniversary, I can sleep peacefully when my time comes.
There will never be another first mission by humans to another world. We should remember that first journey, and honor it. I am glad we finally are doing so.
FCC fines company $900K for unapproved satellite launch
The FCC has issued a $900K fine against the smallsat company Swarm for its unlicensed launch in January on an Indian rocket of four smallsats.
Along with paying a massive fine, Swarm has agreed to submit reports to the FCC before every satellite launch it wants to make for the next three years. These reports must include all of the details about the launch vehicle that will carry the satellites, the time and location of the launch, and contact information for who is coordinating the launch. And Swarm has to do this a lot, too. Reports need to be submitted within five days of Swarm purchasing a ride on a rocket, or within 45 days of the flight. Additional reports must be submitted when the satellites are shipped to be integrated on the rocket, whenever the satellites are actually integrated, and around the time the launch is supposed to take place.
Within the next two months, Swarm must also establish its own “compliance plan” and appoint a compliance officer to make sure the company adheres to all of the regulations surrounding a satellite launch. This entails crafting clearly defined procedures and checklists that every employee must follow to confirm that the FCC’s licensing requirements are being met.
I have very mixed feelings about this. While it is important that the FCC make sure U.S. satellites are compliant with the Outer Space Treaty and that satellite makers and launch companies do not do things willy-nilly without some common sense coordination, this settlement, with its complex bureaucratic paperwork requirements, strikes me more as a power play by the agency to tell everyone that the government will rule here.
At the same time, I can understand the FCC’s concern. We are about to see a smallsat revolution, with tens of thousands of these satellites being built and launched by numerous big and small companies. The FCC wanted it very clear to everyone the need to get that licensing done properly. This settlement makes that clear.
Russia’s Proton launches military satellite
Russia today successfully launched a military communications satellite using its Proton rocket.
This was only the second Proton launch this year, a rocket that was once Russia’s commercial workhorse with a launch rate more akin to what SpaceX has today.
The leaders in the 2018 launch standings:
35 China
20 SpaceX
14 Russia
11 Europe (Arianespace)
8 ULA
China leads the U.S. in the national rankings, 35 to 33.
