The good folks at NASA, ever managing to be on the leading edge, have just launched a competition encouraging teams to develop a system to convert carbon dioxide into glucose. Why is this important? Well, sugar-based biomaterials are plentiful on this planet thanks to our helpful plant life. That will not be the case as we set out among the stars! Developing bioengineering methods to create base materials that will be in short supply (such as easy to metabolize sugars like glucose) from materials that are in great abundance (carbon dioxide) will be a crucial step towards facilitating our successful advancement.

This competition is broken into two phases:

  • Phase 1: Teams submit a design and description of a method to perform the stipulated conversion. Up to 5 teams will be awared $50,000 each, as will be announced in April 2019.
  • Phase 2: Actually building a working system to perform the conversion. The successful team will walk away with $750,000.

This new contest is part of NASA’s Centennial Challenges program, which was initiated in 2005, intended to directly engage the public in advanced technology development. Basically, NASA is being very observant and starting to crowd-source ideas and research, which makes a great deal of sense in our current world.

Mars Dust Storm Finally Slowing

A planet-wide dust storm, which was first seen on May 30, 2018, is finally winding down on the windy red planet. NASA’s rover Opportunity, which is solar powered, has suffered a shutdown as a result of this storm – going into what amounts to hibernation to ride out the storm. However, that dormant period has been longer and more intense than originally designed to handle, so everyone is on edge waiting to see if we can get the rover back on line.

Signals are being sent to the 15 year old rover, which is tucked away in Perseverance Valley, in the hope that once the batteries are recharged even a little, the unit will initiate recovery procedures.

We’ll keep you posted on the status of this fan-favorite rover; and hopefully some readers of this site will one day visit it in a science museum with 38% the surface gravity of Earth.

SpaceX – Pad 39a Crew Access Arm

One of the great things about having a genius-level CEO who is hell-bent on pushing mankind into the world they expected to already exist and is a massive sci-fi fan, is that the design aesthetic for everything his companies do is very consciously ‘futuristic’. And why not? It is fantastic to boldly own the fact that we really should look like the Jestons by now, instead of something from the set of 1984’s Repo Man.

A perfect example of this is the new Crew Access Arm (CAA) that SpaceX has installed on Pad 39a at Cape Canaveral. Seeing crew-based hardware going back up on this historic pad should make anyone familiar with recent history very excited, as it was from this very location that all Apollo missions to the moon, powered by the Saturn V, were launched along with many of the more recent Shuttle missions. Restoring that capability to American soil, through American inginuity is something we should all be proud of, and is something to be recognized and celebrated.

From a broader perspective – I believe firmly that the exploration and development of space will be a unifying force for a fractured world. Certainly there will be some unexpected struggles, as there always are, but I think that humans need a sense of adventure and exploration. It’s part of our makeup. We are lacking that now, and spinning our wheels with reality shows and iPhone apps, and basically circling the drain without a shared purpose. Space will be that purpose, and I feel will allow us to lift up from the state in which we find ourselves and achieve the next, better stage of our enlightened development, together as one people.

Last week, SpaceX hosted a closed-door. invitation only Mars workshop, intended to bring together an interdisciplinary team of industry leading experts to discuss the plan for the red planet. Details on this meeting are, as you would imagine, still pretty minimal, but it is encouraging that this sort of thing is starting to ramp up, and the right questions are being asked of the right people.

A recent criticism that has been lodged against SpaceX is that they are very focused and successful with solving the engineering problems required to improve rocket technology and build the pathway to Mars. However, the amount of time spent considering the human factor, and how difficult it will be to keep astronauts alive both on the journey as well as once they have arrived is far less. Challenges ranging from radiation exposure (in space and on the surface) to adequate supplies to the ‘dust problem’ to basic human interactions all need to be considered and seriously addressed. Since Musk’s companies all show a propensity for thinking of the edge cases and surprising us when we think they are missing an angle, I maintain great confidence that what needs to be considered, is well under way.

On August 3rd, NASA officially named the astronauts who will fly on the SpaceX and Boeing crew modules destined for the International Space Station. This is a tremendously important step, as it is allowing the US to reclaim their own access to space instead of relying on Russian launch capability as it has since 2011 when the Shuttle was officially mothballed.

On the SpaceX Crew Dragon:

  • (test flight) Col. Bob Behnken of the Air Force
  • (test flight) Doug Hurley, a retired Marine Corps colonel
  • (ISS) Mike Hopkins, Air Force colonel
  • (ISS) Victor Glover, Navy commander

On the Boeing CST-100 Starliner:

  • (test flight) Eric Boe, a former space shuttle pilot who retired from the Air Force
  • (test flight) Christopher Ferguson, a Boeing astronaut who left NASA in 2011
  • (test flight) Lt. Col. Nicole Mann of the Marine Corps
  • (ISS) Williams, a retired Navy captain
  • (ISS) Cmdr. Josh Cassada of the Navy

The test flights will be here before we know it, with uncrewed flights of the new modules scheduled for late 2018, and the first human test flights slated for mid-2019.

Mars – as Close as it Gets

NASA is reminding everyone that today, July 31st 2018, is the closest Mars will be to Earth for the next 269 years, at a distance of 35.8 million miles (57.6 million kilometers). That means, unless those of us alive now are very very lucky and some medical advances happen in the next 10-20 years, we probably won’t be around for the next one.

If it is cloudy where you are, don’t stress too much – the next close approach, while not prize winning, will still be fun to observe and will take place Oct. 6, 2020.

So – get out there and keep watching the skies!

A team from the Italian National Institute for Astrophysics, using Marsis, a radar instrument on board the European Space Agency’s (Esa) Mars Express orbiter, believe they have discovered a nearly 20km (12 mile) underground liquid water lake on everyone’s favorite backup planet. This is significant for oh so many reasons, and we need to get a probe over there stat and see about what may be swimming around.

The technique for finding this new Mars feature utilized the radar capability of Marsis, and the team realized that reflections from the bottom of a subsurface feature were stronger than reflections from the surface which, in radar terms, is a good sign of liquid H2O.

Fluvial Stream Evidence on Mars

Mars has a lot of interesting surface features, and a new study claims to have decent reason to believe that many of the structures which resemble fluvial stream networks on Earth were formed by the same processes on Mars. Namely, it speaks to the existence of a climate and atmosphere which was able to support frequent and heavy rainfall, on a planet that may have been much wetter than even we had thought.

This all goes to show that Mars continues to surprise us, the more we learn about it, and that the vast undertaking of coming to terms with an entirely new celestial body is more meaningful and challenging than we can imagine.

Wind Power on Mars

A new study from Boston University’s Center for Space Physics has determined that wind is an effective option for power generation on Mars! This is especially important to combat times of low solar activity such as we are seeing with the current dust storm, and to balance power needs when a piece of equipment may be in a limited sunlight environment for half the year. Additionally, radioisotope power (ie. nuclear) as powers the Curiosity rover would be counter-indicated in a polar region as it would impact any science experiments being conducted.

The original experiments for this paper were conducted in 2010. At the time it was determined that wind was a possible power source given climate conditions on the Red Planet, however there were concerns over the required size of the turbines given the state of technology at the time. Now with 8 more years of materials science and research behind us, the equipment that could be deployed for this purpose has sufficiently improved that it truly can be seen as a viable option. Another great step forward for Mars!

Rapid Mars Planet Formation Gave it a Head Start

Mars Crust Formed Early
(Image Credit: JPL/NASA)

When the starting whistle of the universe blew, and our solar system began to coalesce, it now turns out that Mars was running laps around the Earth in terms of planet formation. This is important because it means the planet would have had more than a 100-million-year head start over Earth regarding the development of a viable habitat. The report in the June 27th issue of Nature states that only 20 million years after the dust and gas around our sun had started to form the planets, Mars was up and running!

While these discoveries about the early crust formation on Mars may suggest a longer timeframe for possible development of life, it also indicates a relatively thin atmosphere which is a disappointing side note to this work. I suppose none of that will be terribly important once we start terraforming the place, and restoring it to the former glory of a green and blue world!
