Enhancing human radioresistance for deep space exploration and colonization

Human Radioresistance

Being able to write that headline in a non-ironic, non-fantastical context because we are finally living in ‘the future’ makes for a really wonderful evening. While the paper may be a stretch in places, it’s worth it for the 289 references alone. These footnotes cull together a dizzying array of bio and health and spacetech papers all seemingly converging on the ability to ‘enhance’ humans and make us more immune to the deleterious effects of off-Earth radiation.

The basic premise here, in this actual scientific paper which is published at oncotarget.com, is that tweaks can be made to the human body via gene therapy and other methods which will improve both resistance and repair to the damage caused by high-Linear transfer (high-LET) radiation. I think an excerpt from the abstract will say it best:

Herein, we lay the foundations of a roadmap toward enhancing human radioresistance for the purposes of deep space colonization and exploration. We outline future research directions toward the goal of enhancing human radioresistance, including upregulation of endogenous repair and radioprotective mechanisms, possible leeways into gene therapy in order to enhance radioresistance via the translation of exogenous and engineered DNA repair and radioprotective mechanisms, the substitution of organic molecules with fortified isoforms, and methods of slowing metabolic activity while preserving cognitive function.

Be sure to check out this exciting new paper, and enjoy the fact that we are living in a time where this sort of topic is not only seriously discussed, but about to be an important part of getting mankind to the stars.

Marsbees

NASA has finally taken a page from the SpaceX playbook, and realizes how important marketing and branding is to this stage of the growth of spaceflight. Well, that’s not strictly fair since they were the original hypemen with the Apollo Program in the 1960s, they have just rediscovered their way.

I’m referring specifically to the fantastic new plan released by the agency to deploy a swarm of flying robots about the size of a bee, which can more effectively explore the variable surface of Mars without having to roll over top of it. This system would be paired with a new rover, which would act as a charging station for the marsbees as well as a communication hub to download their data and transmit it back to mission control.

What a fantastic plan! Now we are starting to think, and the leap in understanding of the martian surface and atmosphere will be tremendous when this system comes on line. Stay tuned to the Mars Gazette for all the updates!

(Thanks NASA !)

NASA’s Insight Lander Launch – May 5th

It is tempting to focus on the flash and success of SpaceX, owing to their masterful execution of new engineering triumphs and spot-on marketing efforts. However, it is also worth remembering that little to none of this would be possible without the granddaddy of them all – NASA – who is still working hard and producing valuable results in the Mars arena.

The new NASA Insight Lander is set to launch to the Red Planet on May 5th, which would give it an arrival date of November 26th 2018. Weighing in at 1,530 pounds, the primary mission of the lander is to study the planetary interior, attempting to detect tremors and studying heat which is coming from the mantle and core. “In essence, it will take the vital signs of Mars — its pulse, temperature and much more,” said Thomas Zurbuchen, head of NASA’s science division. “We like to say it’s the first thorough checkup since the planet formed four-and-a-half billion years ago.”

First-ever luxury hotel in space

Aurora Station
This is exactly the sort of accelerated pace that I hoped, in my fondest wishes, would be a direct result of the recent Falcon Heavy launch and subsequent spaced Tesla roadster. I am convinced that it will encourage and unleash a flood of entrepreneurial excitement and draw the attention of investors and boardroom executives from all corners of the world. Reading today an announcement of a planned “first ever luxury hotel in space” helps to joyously confirm my hopeful assumptions.

The past three days have seen the Space 2.0 Summit held in San Jose, and I will absolutely have to investigate further what was discussed there, since one of the items to emerge was the Aurora Station project proposed by developer Orion Span. This exciting new company is chartered to “build and sustain human communities in space” and I wish them goodspeed and the best success; as they say, a rising tide raises all boats, and I think this starts to show how Elon has opened the floodgates.

Dragon Connects with ISS

Dragon Docks with ISS
In a follow-up from the story on Monday regarding the successful launch of the Dragon cargo capsule on the NASA resupply mission, word has been received today that docking with the ISS was successful. The 3 tons of supplies have been delivered safely to the orbiting space station, and the Dragon will remain connected for the whole of April, after which time it will be sent back to earth, again loaded this time with outgoing supplies. Landing will take place in the pacific where SpaceX will retrieve the capsule after it’s second successful mission.

At current design tolerances, the Dragon capsules are rated for three missions, so this one may have yet another trip in the future. The goal of re-usability is not only here, but has now been proven to work over and over again, with the results showing clearly in the price to orbit.

Stellar Jurisdiction

Star Laws
There is an interesting article over at SpaceNews today regarding the peculiar and sudden imaging restriction imposed by NOAA on SpaceX in the middle of their Falcon 9 launch last Friday. While conflicting reports had been surfacing, including from NOAA themselves, it seems that the truth of the matter has finally begun to surface, and in so doing may be handily managed by the fleet of lawyers.

It boils down to restrictions on images of Earth taken from orbit, and a number of bureaucratic hoops one must jump through in order to proceed with that sort of event. What really gets my goat however, is the notion that one government (apparently our own) can claim to exercise rights over imaging of the entire Earth from points in orbit which would only briefly even be over top of the US.

It raises in my mind the much larger and more important question of: who “owns” the moon and other planets? Or at least, who claims to? I like to think that Elon and co. can simply get to Mars, set up whatever they like, and then suggest that if someone doesn’t like it they can come there and ask him to stop. The idea that the US (or any nation) would claim to have jurisdiction over the moon or Mars – when so abjectly failing to get us there themselves – is frustrating to say the least. I’m looking forward to seeing that all play out, sooner than we ever expected!

Falcon 9 Launch, Monday 4/2/2018

Dragon capsule docking with space station

SpaceX has committed to a very aggressive launch schedule for the remainder of 2018, and this back-to-back demonstration of master level rocketry is a direct result! We just finished cheering and celebrating the successful launch on Friday (albeit with shortened video thanks to NOAA involvement) and now we look ahead to the scheduled 4:30pm EDT Monday afternoon launch of a Space Station resupply mission.

This will be the 14th mission (code named CRS-14) for SpaceX under the ‘Commercial Resupply Services Contract’ from NASA, and will include about 5,800 pounds of equipment. This is a repeat attempt of a launch which was delayed from February 9th and again from March 13th. Unfortunately the current plan is not to attempt a landing and recovery of this booster, which has flown before and is being reused for this flight – a key feature of Elon Musk’s strategy for reducing the costs of commercial space flight. The rocket will be pushed to the edge of some trajectory limits in order to capture useful mission data, and will be expended upon reentry. Since SpaceX is gearing up to release their new Block 5 version of the Falcon 9, recent (and likely upcoming) missions are cycling out the old Falcon boosters to make way for the new and improved 2018 model. Won’t that be great – when we are versioning rockets as commonly as we do with automobiles?

SpaceX Falcon 9 “Block 5” First Flight April 24th

Falcon Block 5
Never content to sit idly by and allow would-be competitors to play catch-up, SpaceX has been hard at work on a new Falcon model code named the ‘Block 5’. Improvements include:

  • 7-8% more thrust from the engines
  • an improved flight control system for an optimized angle of attack on the descent
  • a reusable heat shield protecting the engines and plumbing at the base of the rocket
  • a set of black retractable landing legs for rapid recovery and shipping

…and plenty more features guaranteed to make this another superstar of a rocket.

After months of careful testing, a launch date for the first Block 5 flight has been announced of April 24th. Many things can cause such a window to be adjusted, but that one will go on the calendar and hopefully demo to us all that new and improved platform!

SpaceX Autonomous Spaceport Drone Ships – OCISLY – Part 1

SpaceX Autonomous Spaceport Drone Ships - OCISLY

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.

Bottom Mounted L-Drive Azimuthing Thruster

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).
