Are you interested to learn more about the robot boats (officially ‘Autonomous Spaceport Drone Ships’ or ASDS) that are part of the SpaceX fleet, whose primary mission is to facilitate the recovery of rocket first-stages at sea? Of course you are! So am I! The scope and breadth of what it means for a company to pursue a single minded goal, and to invent from whole-cloth anything they may require to get there is evident in so many aspects of the SpaceX operation. One small corner of that process – which could easily masquerade as an entire industry on its own – are the autonomous drone ships. Delightfully named after craft in the Iain M. Banks Culture series of novels, these ships contain their share of tech which should make other industries blush at the audacity of no-holds-barred, forward thinking innovation.
This will be the first of a multi-part series that dives into the known technology behind the drone ships, and today we will start with the engines.
Each of the football-field-sized ships (“Just Read the Instructions” stationed at the Port of LA, “Of Course I Still Love You” and the under construction “A Shortfall of Gravitas” based out of Port Canaveral) are driven by four diesel powered azimuth thrusters made by Thrustmaster. These marine propellers are designed to be rotated to any angle, allowing for high precision steering and the elimination of the rudder.
While it isn’t clear yet which model is being used on the ASDS, a likely candidate is the Bottom Mounted L-Drive Azimuthing Thruster, which specializes in absolute positioning capability for offshore supply vessels.
Their largest model of this line is the TH10000ML with an 8000 kW motor. Operating at a peak of 720 RPM, this drive is capable of generating 1337 kN of thrust and weighs in at a remarkable 194,006lbs. I like to imagine that there are 4 of these beasts under each recovery platform, and there are suggestions that these main engines are further assisted by additional smaller drive systems, all computer synchronized and coordinated with a proprietary GPS system.
The design specification of the SpaceX vessels, which are based on Marmac barge hulls, is that they must be capable of precision positioning within 3 meters even under storm conditions at sea. Imagine, keeping this floating platform stable enough to vertically land a rocket, then keep it steady enough to not simply tip over before it is secured through a combination of robotic and human assistants (the subject of a future article).

Take note, SpaceX fans, that the Los Angeles Board of Harbor Commissioners has just approved a plan by SpaceX to lease an 18-acre site at the Port and a 200,000 square-foot space to be used for manufacturing. I think we have our BFR production facility, and things could hardly be more exciting! This space is right next to where everyone’s favorite drone ship, the Of Course I Still Love You, is docked and ready to be mustered into action. Looks like a brand new space-coast is emerging!
Elon Musk wants us all to be able to wake up in the morning and have something grand to look forward to. Well, he is single-handedly making that happen for many of us with his constant output of exciting work. This bright Monday morning we can have a look at a sizzle reel featuring crewed transport on their Dragon launch system, and more about their snazzy spacesuits. I especially like the very last scene!
Defying nearly all odds for a human with amyotrophic lateral sclerosis, Stephen Hawking lived an amazing and productive life for 55 years after the initial diagnosis wherein he was given only a handful of years to survive. He became a household name for both lofty intellectuals and folks with even a passing interest in science, and shared his insights and passion with us fortunate souls as the world sped up around him.
In recent years one of his most vocal positions was that humanity absolutely must become a multi-planetary species, or face certain extinction from any one of a number of possible events: nuclear war, violent climate change, unexpected asteroids, or a sudden willful descent into the plot of Idiocracy. Not keeping all of the eggs in one basket is a good, pragmatic approach to nearly any endeavor, and the preservation of the human race should be paramount among them. Over the years, as we crested the milestone of the year 2000, and now find ourselves well into that century, he became increasingly frustrated at the lack of apparent interest or progress in returning humanity to the stars.
As we report on Mars Gazette with great fervor, the recent Falcon Heavy launch by SpaceX is, without doubt, the most purposeful, solidly executed and clearly stated step yet taken by mankind to honestly pursue and achieve that goal of human settlement offworld. I, as many others, mourn Dr. Hawking’s passing, though wonder if it may have been somewhat eased by this amazing scientific and social achievement. After so many decades of pain, tenacity and the stiffest of all British upper-lips, he managed to live long enough to see that step taken. He knew that he had fought long enough to see humanity finally achieve that next phase of our collective evolution, sometimes in spite of ourselves, and that the cause he had championed as one of his main projects in his twilight years would now be carried to completion. He could finally rest, knowing that humanity would carry on.
Another new article for your consideration, with expanded interview coverage of Elon Musk’s discussion at SXSW last weekend. In it he expands further on his goal for sending the Tesla roadster into space, and it’s every ounce as wonderful and selfless as I expected. I am still astonished at the ability for naysayers, especially those in the scientific community, to continue to devise areas of complaint about any aspect of his work. I can attribute it only to the most tragic of sour grapes, exposing a great degree of hypocrisy and infighting in the scientific community. It is fortunate that once in a generation a visionary may emerge, and be able to secure the resources needed to drive towards a great goal with singleness of purpose.
“Life cannot just be about solving one sad problem after another…There need to be things that inspire you, that make you glad to wake up in the morning and be part of humanity. That is why we did it. We did for you.”
The Westworld team, and everyone’s favorite savior of mankind Elon Musk have released a beautiful short video commemorating the incredible and wildly successful Falcon Heavy launch on February 6th 2018. It is most definitely worth a watch, and there is even a short clip of the center booster missing the OCISLU drone ship, which is transparency we can all appreciate. No matter how often I replay the events of that launch in my head, it remains amazing and so very important.
One of the hesitations to considering life on other worlds, for many, will be how to cope with the truly unsettling experience of leaving behind everything you know in exchange for an alien landscape. Well, our nearby neighbor may be more welcoming than many realize, if only you take the time to appreciate the little things. Take, for example, the new beautiful image from the Mars Reconnaissance Orbiter which appears to show a familiar process of frost heaves, which has led to boulders being forced to the surface.
So, now you can have a blue sunset, frost heaves, and a giant statue of Elon Musk in the town square. What more can you ask for.

Any day where I can wake up and watch a successful rocket launch that took place earlier that morning delights me by proving we, as a people, are doing at least one thing right. This was the historic 50th Falcon 9 launch by SpaceX and Elon Musk (founder, CEO, lead designer, savior of mankind) and as we have already grown to expect, it went off without a hitch.
Unfortunately storm conditions and very high seas prevented everyone’s favorite drone ship, the “Of Course I Still Love You” from retrieving the first stage, which had to be abandoned to the sea. However, the mission was a success, and Hispasat 30W-6 was placed into geosynchronous transfer orbit, there to provide telecommunication services to areas around the globe.

The moon will have a 4G mobile network installed next year, according to plans set out by Vodafone and Nokia.
The mission, organised by space exploration company PTScientists, will be the first privately funded moon landing.
Nokia masts will be launched on a SpaceX rocket in 2019 from Cape Canaveral air force station in Florida.
The network will enable Audi lunar exploration vehicles to communicate with each other and with a base station. The 4G signal, provided by Vodafone, will also be able to transmit high-definition video streaming of the moon’s surface.
This ambitious and exciting project is scheduled for 50 years after NASA first accomplished getting humans to the lunar surface!

“The UAE hopes to become the first Arab state to send a mission to the red planet, by designing, developing, manufacturing and eventually controlling a probe. The country doesn’t have its own rocket technology so it will have to rely on companies such as Mitsubishi (MSBHY) or Musk’s SpaceX to carry the payload into space.”
Exciting to see Dubai and the UAE throwing their support into the ring. They are people who understand the important places to spend effort and capital, and have correctly identified this as the next big thing!
