Insight Launch Guide: “Witnessing History” (Issue #38)

Guest blog by: Rich Cabral

I would like to extend a very special thanks to Mr. Cabral for his tireless work, dedication, and commitment to ensuring the public has every opportunity to view this historic launch.   -N. Willett

“It should prove to be a real crowd pleaser.” –Col. Gregg Wood, Vice Commander, 30th Space Wing, Vandenberg Air Force Base

Launch window opening:  May 5th, 2018, 4:05-6:05 a.m. PST (7:05-9:05 a.m. EST)

Insight will launch from Space Launch Complex-3 (SLC-3), Vandenberg Air Force Base, California, aboard an Atlas V-401.  The rocket will fly in a 401 vehicle configuration and will have no side mounted boosters.

The Mission:  Insight is the first West Coast Interplanetary Launch.   All previous interplanetary launches have been from the Kennedy Space Center, Florida.

“InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the “inner space” of Mars: its crust, mantle, and core.

Studying Mars’ interior structure answers key questions about the early formation of rocky planets in our inner solar system – Mercury, Venus, Earth, and Mars – more than 4 billion years ago….”  –NASA/JPL

Besides being a major scientific event, Insight is a milestone in the story of humans in space..

Viewing:  recommended viewing sights:  Click the map below for sights, where to get breakfast or an early morning snack, and where to stay if you plan on hanging around “The Valley”.

Safe Viewing:  There’s nothing like a live view of a launch.  The roar of the engines, the white trailing flame, and the crowd of fellow launch enthusiasts: Its exciting, no doubt about it.  But, Vandenberg Air Force Base is, above all, a highly secure Government sight. So, it’s a good idea to be on one’s best behavior during a launch. Base business is serious business.  Military, city, and county police launch presence makes sure that business is respected and understood. Treat those officials with respect and they’ll do everything they can to help.

Weather/Mechanical/Delays:  Central coast weather is temperamental.  Then, there are equipment problems. As a result, weather, mechanical delays and launches go hand-in-hand.   Three attempts before a successful launch is about average.  Less or more attempts are also to be expected.  Plan to go to a launch, based on the understanding it may or may not happen.  Anything else is unrealistic.

Clothing: At 4am it can be cold in the Lompoc Valley.  Dress in layers.

Hotels:  Here’s a list of Lompoc hotels if you plan on staying overnight.

Hilton Garden Inn

Embassy Suites

Lompoc Valley Inn & Suites

O’cairns Inn & Suites

Holiday Inn Express

If Lompoc is sold out, there are hotels in nearby Buellton, Solvang, Santa Maria

Breakfast after the launch:

Hilton Garden Inn, Valle Eatery, 1201 N. H St, Lompoc  93436; opens 5:30 am.  The Hilton is planning on having food available for purchase prior to the launch. Contact the hotel at (805) 735-1880 for more information.

American Host, 113 N. I Street, Lompoc  93436; opens 5:30 am. If the door is locked, knock and ask for Lisa.  Tip:  this is where the launch crew often goes after a launch.

Cajun Café, 1508 N. H Street,  Lompoc  93436; opens  at 6:30 am.

Musically, this is what a launch feels like, particularly at Vandenberg, where the setting, the land itself and the ocean, tell a timeless story of an  epic journey in the human saga: In the early morning hours, with launch lovers all around you, turn up the volume, and know what you are about to witness.

Building Mars: Modeling Permanent Structures Using Mars-Sourced Materials (Issue #37)

Guest Blog By: Lorena Bueno

Edited by: Margaret Lattke

Crack open any mid-level science novel from the last 70 years and you’ll find, among fanciful descriptions of grand canals and sand-scattering weather systems, varied descriptions of what’s underfoot (or boot): Martian sand. Regolith, powder, basalt rock, even clay, hint at a time when Mars had enough water and geologic activity to create clay.

As we plan our first trips to Mars on Earth with the Mars Desert Research Station (MDRS) of the Mars Society, the next few missions on Mars will give us more data on the clay deposits of our near neighbor. With this data we can add clay-based structures to our plans of more permanent structures.

What can we do with clay?

If the clay deposits are significant enough, this ancient building material may give us one of the first resources we can use to help protect and define the boundaries of our research and colonization outposts. While our first clay bricks may be as handmade as those first made on Earth, we’ll bring with us approximately 9,000 years of advanced knowledge and technology. We’d start by studying how clay behaves in the environment of Mars before and after it is shaped into usable chunks. A team of engineers at the University of California San Diego has already created no-bake brick samples out of simulated “Martian Soil”.

While ancient Earthlings mixed, shaped, and dried their bricks outside in sunny, warm climates, that won’t work as well on Mars. We’ll need to create processes on Earth to simulate the kind of brickworks we can create in Mars’ atmosphere (1/100th of our atmosphere here on Earth) or in a pressurized habitat. These experiments will help us figure out how to keep the mixture of clay, water, and other ingredients together long enough to be shaped and finished.

After test bricks of various recipes are created, we’ll simulate how well the bricks wear in a Mars-like environment. First, each type of brick will be tested individually to see how it reacts to the extreme heat and freezing cold temperatures characteristic of a typical Martian day during any season.

Next, we’ll subject the bricks to weather testing: blowing the bricks through a series of Martian storms. Despite what we’ve seen in the movies, the winds of Mars don’t do nearly as much damage as a comparable storm on Earth. Winds on Mars don’t get higher than 60 or 70 miles per hour. That much wind speed on Earth would knock you over! But with Mars’ 1% atmospheric pressure, 60 mph on Mars would feel like 6 mph on Earth just about enough to launch and fly a medium-sized kite.

Then we’ll move on to testing bricks in groups. Studying bricks of different sizes and shapes, set up as solid walls and berms, will determine how they withstand the weather, wind, and dust storms of Mars. We may even skip shaping blocks directly, and simply make a brick “mix” that can be sprayed or extruded into the shapes we need to build our permanent structures.

 

Building walls on Mars … with math

Constructing a protective barrier from Martian-sourced bricks provides its own special engineering challenges. Modern bricks on our planet are bound together using specialized adhesives and mortars; Mars’ thin atmosphere makes those solutions unworkable.

The solution lies in the way the bricks are shaped and stacked. Interlocking bricks, laid in deep, long patterns, can be built up enough to serve as weather berms. By directing the worst gusts of stronger windstorms away from habitats or remote sensor arrays, we can extend the life of the buildings we bring from Earth.

Simple structures can be built with a combination of Earth and Mars materials as well. While we have to live in pressurized habitats, movable equipment, such as rovers or trailers, may only need a simpler protective shelter. Picture a basic structure made up of brick walls topped with solar panels. These shelters can be built around a metal or composite frame with a protective door to keep out the worst of the blowing sands.

We can set up a series of emergency maze-style shelters as well. A shelter you can drive in and out of, designed to keep sand out during a sudden storm. Stage these along known trails or byways to help keep travel between far-flung sites safe.

Though solar panels are a popular means for capturing energy in most of our plans for Mars, we can also corral and use the energy created by the planet’s vast winds. Mars-made bricks might be used to create funnels designed to speed wind through specialized wind turbines, hardened to work on Mars and provide power backup during the worst of the hemispheric or global storms.

Reducing the costs of exploration – Getting more with less

As a species, every dollar we spend learning and exploring lifts us higher. Once we’ve done the hard work of getting the first explorers to our neighboring planet, everything we do there, along with the support of those teams, will make it easier for the next generation of explorers and humans watching from afar.

As humans, we’ve spent our history expanding our horizons, finding new ways to innovate and grow. Taking that tradition, and all we’ve learned, to Mars and beyond, is in our DNA. Sure we can send modules, supplies, food, and people to Mars. However building or augmenting or augmenting permanent structures from local materials gives us more than a way to save money; we can learn from and apply science in the field and export it back “home”.

Origin of Life Theories and Mars Exploration (Issue #36)

Guest Blog by Bob Bruner

Bob Bruner has attended and presented at the scientific conferences described below since 2015.  His contribution is entitled “Special Exhibit on Meteorites and Minerals associated with the Origin of Life on Earth or Mars” and can be found on the web. He is a long-time member of the Mars Society and is a volunteer at the Denver Museum of Nature and Science.

I would like to offer a special THANK YOU to Mr. Bruner for traveling the world to bring us this first hand report and his tireless passion in the pursuit of scientific knowledge. 

 

Four popular origin of life theories that have influenced the hunt for life on Mars.  The first are the clay theories which probably started in the late 1950’s with Dr. Bernal of the UK.  They were further developed in the 1970’s and 1980’s by Dr. Cairns-Smith of the UK, then in the 1990’s by Dr. Ferris of the USA.  They were added to in the 2000’s by Dr. Hashizume of Japan and Dr. Hansma of the USA.  The theories claim that the structure of clay can provide compartments for proto life to begin, with large molecules like RNA developing later.

The second are the Black Smoker-type hydrothermal vents at the bottom of the ocean theories primarily developed by Dr. Wachtershauser of Germany with an emphasis on iron-sulfur and Dr. Mulkidjanian of Germany with an additional emphasis on zinc.  These theories claim that the minerals have the ability of powering the chemical reactions that allow small organic molecules to get larger and larger, ultimately becoming proto life.  They were popular in the 1980’s and 1990’s.

The third are the warm hydrothermal vents at the bottom of the ocean theories primarily developed by Dr. Russell of the USA, Dr. Sleep of the USA, Dr. Schulte of the USA, and Dr. Holm of Sweden.  These theories took off when the Lost City hydrothermal field was discovered by Dr. Kelley of the USA in the 2000’s.  The process of serpentinization, where olivine/pyroxene interacts with CO2 and sea water to produce serpentine, magnetite, brucite, CH4 and H2, gives new proto life energy and food.

The fourth are the surface hydrothermal pool theories which probably started with Darwin in 1859, but gradually fell out of favor until revived by Dr. Deamer and Dr. Damer of the USA in 2016.  They envision small areas of land above a mostly-ocean Earth which contain warm pools interacting with the surrounding environment creating wet-dry cycles which create ever larger organic molecules, ultimately becoming proto life.  Opaline silica and geyserite and sinter line hydrothermal pools.

For many years the clay theories dominated the hunt for life on Mars, not only as proof of water (the existence of clay proves past water) but lately in the case of montmorillonite as a source of food for microbes according to Dr. Craig of the USA.  The next hot theory was black smoker-type hydrothermal vents where abundant life forms were spotted by expeditions to the bottom of the sea.  But some scientists said the hot water would not allow large molecules like RNA to develop.  Then came the warm hydrothermal vents where the water was not too hot for large organic molecules to develop. This theory became the most popular theory because life would be protected from bad things happening on the surface such as bombardment by asteroids and comets.  In fact it was adopted by the Europeans in their roadmap ASTROMAP published in 2015.  But in 2016, the idea that surface hydrothermal pools provide required wet-dry cycles started to dominate.  At the NASA Biosignature Conference in 2016 this idea dominated the conference report so much so that the warm hydrothermal vent people asked for a pre-meeting to produce their own report about rock-

Three Finalists for Mars 2020 Landing Site

water interaction before the 3rd Landing Site Meeting for the Mars2020 rover in 2017.  Even so, the landing site Columbia Hills was still promoted to third place over other sites which had more votes because of the work done by Dr. Van Kranendonk and Dr. Walter of Australia and Dr. Farmer and Dr. Ruff of the USA.  At the 4th Landing Site Meeting for the Exomars 2020 Rover in 2017, the only theory NOT promoted was the Black Smoker-type hydrothermal vent theory.

As one can see, politics among scientists have influenced landing site decisions and have no place if good science is to emerge.  If a voting system was agreed to ahead of the conference, it should be followed.  It was followed at the 4th Landing Site Meeting for Exomars 2020, but it was not followed at the 3rd Landing Site Meeting for Mars2020.

SLC4 The Comeback Kid (Issue #35)

Guest blog by Dale Hammond

Dale Hammond 1This following describes how a California launch facility and a pair of accidents there spoke less about failure and more about the resilience and perseverance of human efforts in orbital space and beyond. Accidental failure occurred not once but twice in the same place within a span of just eight months. But rather than pointing to defeat, the recovery of that facility and the people who worked there led to new and innovative solutions: booster reusability by SLC 4’s current occupant SpaceX and subsequent cost reduction in delivery of payloads to orbit, which is considered paramount to the colonization of Mars. It may also lead in some distant future to the SLC being known in planetary legend and lore as a place that would not go away, that was once and will always be “The Comeback Kid.”  

Space Launch Complex 4, or SLC 4, Vandenberg Air Force Base, began its career as a launch facility for Atlas and Titan rockets. In 1963 two platforms were constructed within the complex: PALC2-3 and PALC2-4. Later, those became what they are known today: SLC 4e and SLC 4w. That whole chapter lasted for 42 years, and then SLC 4 was deactivated. In 2011 it was reactivated, to be leased and refurbished/rebuilt by SLC 4’s next chapter, SpaceX.

Dale Hammond 2Overall, the PALC/SLC years were good and confidence was high. There were 161 launches at the complex, including the Titan family and the Atlas family of launch boosters. And if this graph from spacelaunchreport.com showing worldwide launches per year is any indication, the past performance of the PALC/SLC tracked, if not improved on, that launch history. Hence, one might assume, like the worldwide success rate, the overall success rate at SLC 4 through 2005 sat at least around 95%.

However, space presents a well-known slim margin of error. As Gary Payton, Deputy Under Secretary of the Air Force for Space Programs said, “Launch reliability is my top priority. Our constellations for any of our missions cannot tolerate a launch failure.” Further, boosters are not a dime a dozen. Richard M. Rocket, co-founder and CEO of New Space Global, speaking in the wake of a 2015 launch failure said, “It’s not like you can just jump to another launch vehicle.” Each booster is one of a kind, designed for a single purpose and a specific payload. In such a world, failure is not an option: when failure comes, it’s painful.

Dale Hammond 3But failure, it should be said, is a necessary stepping stone to achieving dreams, whether they are orbital space, lunar exploration, or Mars exploration and colonization. Correspondingly, if there are any years in the American Space program that best embody that characterization, 1985-1986 could be called “model stepping stones.” The most tragic and most publicized incident was the untimely demise of the Space Shuttle Challenger on January 28, 1986. It caused a suspension of the shuttle program for 32 months and formation of the Rogers Commission, appointed by President Ronald Reagan and assigned the task of discovering what exactly went wrong.

As for Vandenberg Air Force Base in the wake of the Challenger accident, it was dealt an indirect but personal blow as the Air Force elected to cancel use of Vandenberg’s Space Launch Complex 6 (SLC 6) for classified Shuttle military launches. Less known of that period are the ’85 and ’86 launch accidents at SLC 6’s Vandenberg neighbor, SLC 4.

Dale Hammond 4By the middle of 1985 at SLC 4, no Titan had failed in 18 years. Then August 18, 1985, came along. At SLC 4e a Titan 34D-7 was poised on the launch pad carrying a KH-11 photo-reconnaissance satellite. The mighty Titan lifted off and had a good flight – but not for long. In rapid succession, an unplanned complete engine shutdown, a computer glitch and a premature stage separation led to the Titan tumbling disastrously toward land. At T+272 seconds the destruct command was given, and not long afterward, the Titan sank to its permanent residence, a Pacific grave. Its team, that group of dedicated scientists, engineers and technicians who gave life to the Titan, sought solace in what little was left.

But moving forward when all seems lost was in the nature of the SLC 4 crew. They went back to work and found what they believed to be the cause of failure. Corrections were made, and a little under eight months later SLC 4 was ready for another Titan launch.

It was clear on the morning of April 18, 1986: a good day for a launch. This time a Titan 34D-9 was ready to send up a KH-9 photo-reconnaissance satellite.

10:45AM. The Titan headed aloft. Then just above the SLC, the craft erupted into a ball of flame. Debris and toxic propellant showered down on both SLC 4e and SLC 4w. Fortunately, there were no lives lost. But the launch facility was in ruins.

As President Theodore Roosevelt once said, “The credit belongs to the man [or woman] who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself [or herself] in a worthy cause.”

So strive they did. Just 14 months later, in October 1987, SLC 4e reopened. It went on to host the successful launch of two more Titan 34D’s, as well as many other launches.

SLC 4e’s career is far from over. SpaceX is its new, famous occupant, and if SpaceX CEO and CTO Elon Musk’s goal of Mars colonization becomes reality, SLC 4e, “The Comeback Kid,” and the people there who make it all happen will be on the job time and again, carrying on the tradition of resilience and perseverance for humanity’s multi-planet future.

It’s Never too Late to Fulfill Your Childhood Dreams (Issue #34)

Guest Blog by Bob Bruner

Bob Bruner is an amateur scientist that has attended all the Case for Mars conferences given by the Mars Underground in the 1980’s and 1990’s and joined the Mars Society at its founding.  This story is a case of an amateur scientist actually having an impact on NASA decisions for its next big mission to Mars, the Mars2020 rover, by suggesting a specific mineral to cache and return to Earth in the 2020’s.

blog 234 deiviant artThe new year is a time many of us look back on what has been accomplished and look forward to the promises the future holds.  I grew up in Des Moines, Iowa, and in 1948, when I turned 10, my father gave me a 3-inch diameter reflecting telescope with a cardboard tube with which to observe the stars and planets.  My uncle gave me a box of rocks and minerals of many shapes and colors.  I spent many a summer evening looking through the telescope, mainly at planets like Jupiter, Saturn, Venus and Mars.  I also collected more rocks and minerals to go with my starter collection.  Little did I know how important collecting rocks and minerals would be in the future.

When I went to college, I wanted to be an astronomer, but I didn’t understand calculus, so I switched my major to business, and spent my entire working life in the business world.  I retired in 2001, but I had continued my interest in astronomy, volunteered at the Denver Museum of Nature and Science in the Space Sciences Department, and joined the Mars Society.

blog 22 MarsAsteroidImpactWhen Dr. Stephen Benner presented his idea that life must have started on Mars and then been brought to Earth on meteorites,  I really liked his way of “thinking outside the box”.  He said that in order to create RNA, the precursor of DNA, you had to have stabilizing minerals such as boron and molybdenum, which were probably not available on early Earth.  The Mars Society Education Department had a blog on this in September, 2013.  I helped with the blog, and as a result, I was able to get into my first scientific meeting with a poster because Dr. Benner remembered me.  The meeting was the Gordon Origin of Life Conference of 2014 in Galveston, Texas.  My poster was entitled “Meteorites and Minerals associated with the Origin of Life”.  I read a lot about the origin of life and picked the meteorites and minerals I thought would be appropriate.  No publication is allowed after a Gordon conference. It is considered a “starter conference” for new grads, post-docs, etc.

In 2014, I re-packaged the exhibit, expanded it, and applied to the 8th International Mars Conference (only held every few years by NASA).  By a lucky coincidence, this conference specifically asked for a contribution from the Origin of Life community, so I hit it just right.  My poster was on display in the courtyard of Caltech, and I attended along with 650 scientists from all over the world, including those who had been my inspiration for many years. I made it into the ISSOL (International Society for the Study of the Origin of Life) and was published on the conference website.  I made many friends in the Mars scientific community.

blog 34 noaaOne of the theories of the Origin of Life is that life started near hydrothermal vents at the bottom of the ocean in environments known as “Lost City” after that discovery in the Atlantic Ocean.  I met a scientist, Dr. Mike Russell of JPL, at the Gordon conference after his lecture, and felt his ideas had a lot of merit. I felt this same process could have happened on Mars. So when NASA held the 1st landing site meeting for the Mars2020 rover, I sent in the idea in an email to the chairman of the meeting. It  was too late, but I could submit it for  the next meeting. This summer the 2nd Landing Site meeting for the Mars2020 rover was held in Pasadena, California just a few miles from Caltech.  Not only was my idea accepted, but I was allowed 10 minutes on the agenda.  I collected all the minerals involved with the process at Lost City called “serpentinization”, and interviewed all the top scientists who had developed this theory over the last 15 years.  Again I got published on the conference website.  The idea is to cache for return to Earth samples of serpentine, a mineral created by serpentinization to examine it for signs of life.

Bob Bruner blog 34So instead of looking through a telescope to spot Martians, like I was trying to do in 1948, I used my rock-collecting skills to assemble exhibits acceptable to NASA in the 21st Century.  I never dreamed this would happen.  But if one keeps on trying, anything is possible.
