NASA vs. Cigarettes: A Numbers Game

People often criticize the amount of money spent on space exploration. Sometimes it’s well-meaning friends and family who say that that money is wasted, and would be better spent on solving problems here on Earth. In fact, that’s a whole cultural meme. You see it played out over and over in the comments section whenever mainstream media covers a space story.

While solving problems here on Earth is noble, and the right thing to do, it’s worth pointing out that the premier space exploration body on Earth, NASA, actually has a tiny budget. When you compare NASA’s budget to what people spend on cigarettes, NASA looks pretty good.

Ignoring for the moment the fact that we don’t know how to solve all the problems here on Earth, let’s look at NASA’s budget over the years, and compare it to something that is truly a waste of money: cigarettes and tobacco.

NASA is over 50 years old. In its first year, its budget was $89 million. (That’s about $732 million in today’s dollars.) In that same year, Americans spent about $6 billion on cigarettes and tobacco.

From 1969 to 1972, NASA’s Apollo Program landed 12 men on the Moon. They won the Space Race and established a moment that will echo through the ages, no matter what else humanity does: the first human footsteps anywhere other than Earth. In those four years, NASA’s combined budget was $14.8 billion. In that same time period, Americans spent over twice as much—$32 billion—on smoking.

In 1981, NASA launched its first space shuttle, the Columbia (STS-1). NASA’s budget that year was $5.5 billion. That same year, the American population spent about $17.4 billion on tobacco. That’s three times NASA’s budget. How many more shuttle flights could there have been? How much more science?

In 1990, NASA launched the Hubble Space Telescope into Low Earth Orbit (LEO.) The Hubble has been called the most successful science project in history, and Universe Today readers probably don’t need to be told why. The Hubble is responsible for a laundry list of discoveries and observations, and has engaged millions of people around the world in space science and discovery. In that year, NASA had a budget of $12.4 billion. And smoking? In 1990, Americans smoked their way through $26.5 billion of tobacco.

In 2012, NASA had a budget of $16.8 billion. In that year, NASA successfully landed the Mars Science Laboratory (MSL) Curiosity on Mars, at a cost of $2.5 billion. Also that year, American lungs processed $44 billion worth of tobacco. That’s the equivalent of 17 Curiosity rovers!

There was an enormous scientific debate around where Curiosity should land, in order to maximize the science. Scientific teams competed to have their site chosen, and eventually the Gale Crater was selected as the most promising site. Gale is a meteor crater, and was chosen because it shows signs of running water, as well as evidence of layered geology including clays and minerals.

But other equally tantalizing sites were in contention, including Holden Crater, where a massive and catastrophic flood took place, and where ancient sediments lie exposed on the floor of the crater, ready for study. Or Mawrth Vallis, another site that suffered a massive flood, which exposed layers of clay minerals formed in the presence of water. With the money spent on tobacco in 2012 ($44 billion!) we could have had a top ten list of landing sites on Mars, and put a rover at each one.

Think of all that science.

NASA’s budget is always a source of controversy, and that’s certainly true of another of NASA’s big projects: The James Webb Space Telescope (JWST.) Space enthusiasts are eagerly awaiting the launch of the JWST, planned for October 2018. The JWST will take up residence at the second Lagrange Point (L2,) where it will spend 5-10 years studying the formation of galaxies, stars, and planetary systems from the Big Bang until now. It will also investigate the potential for life in other solar systems.

Initially the JWST’s cost was set at $1.6 billion and it was supposed to launch in 2011. But now it’s set for October 2018, and its cost has grown to $8.8 billion. It sounds outrageous, almost $9 billion for a space telescope, and Congress considered scrapping the entire project. But what’s even more outrageous is that Americans are projected to spend over $50 billion on tobacco in 2018.

When people in the future look back at NASA and what it was able to accomplish in the latter half of the 20th century and the beginning of the 21st century, they’ll think two things: First, they’ll think how amazing it was that NASA did what it did. The Moon landings, the Shuttle program, the Hubble, Curiosity, and the James Webb.

Then, they’ll be saddened by how much more could’ve been done collectively, if so much money hadn’t been wasted on something as deadly as smoking.

Protecting Juno’s Heart

Juno computer generated image. NASA/JPL-CalTech

Each new probe we launch into space follows a finely-tuned, predetermined trajectory that opens up a new avenue of understanding into our solar system and our universe. The results from each probe shapes the objectives of the next. Each probe is built with maximum science in mind, and is designed to answer crucial questions and build our understanding of astronomy, cosmology, astrophysics, and planetary studies.

The Juno probe is no different. When it arrives at Jupiter in July 2016, it will begin working on a checklist of scientific questions about Jupiter.

But there’s a problem.

upiter's structure and composition. (Image Credit: Kelvinsong CC by S.A. 3.0) — Jupiter’s structure and composition. (Image Credit: Kelvinsong CC by S.A. 3.0)

Jupiter is enormous. And at it’s heart is a chunk of ice and rock, or so we think. Surrounding that is an enormous region of liquid metallic hydrogen. This core is 10 to 20 times as massive as Earth’s, and it’s rotating. As it rotates, it generates a powerful magnetic field that draws in particles from the sun, then whips them into a near-light-speed frenzy. This whirlwind of radiation devastates anything that gets too close.

Enter the tiny Juno spacecraft, about the size of a bus. Juno has to get close to Jupiter to do its work—within 5,000km (3,100 miles) above the cloud tops—and though it’s designed to weave its way carefully past Jupiter’s most dangerous radiation fields, its orbits will still expose it to the paper-shredder effect of those fields. There’s no way around it.

Juno Project Scientist Steve Levin, and Dave Stevenson from Caltech explain Juno’s orbiting pattern in this short video:

The most vulnerable part of Juno is the sensitive electronics that are the heart and brains of the spacecraft. Jupiter’s extreme radiation would quickly destroy Juno’s sensitive systems, and the Juno designers had to come up with a way to protect those components while Juno does its work. The solution? The titanium vault.

All kinds of materials and methods have been employed to protect spacecraft electronics, but this is the first time that titanium has been tried. Titanium is renowned for its light weight and its strength. It’s used in all kinds of demanding manufacturing applications here on Earth.

The titanium vault won’t protect Juno’s heart forever. In fact, some of the components are not expected to last the length of the mission. The radiation will slowly degrade the titanium, as high velocity particles punch microscopic holes in it. Bit by bit, radiation will perforate the vault, and the electronics within will be exposed. And as the electronic systems stop functioning, one by one, Juno will slowly become brain-dead, before plunging purposefully into Jupiter.

But Juno won’t die in vain. It will answer important questions about Jupiter’s core, atmospheric composition, planetary evolution, magnetosphere, polar auroras, gravitational field, and more. The spacecraft’s onboard camera, the Junocam, also promises to capture stunning images of Jupiter. But beyond all that, Juno—and its titanium vault—will show us how good we are at protecting spacecraft from extreme radiation.

Juno is still over 160 million km (100 million miles) from Jupiter and is fully functional. Once it arrives, it will insert itself into orbit and begin to do its job. How well it can do its job, and for how long, will depend on how effectively the titanium vault shields Juno’s heart.

Ion Propulsion: The Key to Deep Space Exploration

The comforting blue glow of an ion drive. Image Credit: NASA

When we think of space travel, we tend to picture a massive rocket blasting off from Earth, with huge blast streams of fire and smoke coming out the bottom, as the enormous machine struggles to escape Earth’s gravity. Rockets are our only option for escaping Earth’s gravity well—for now. But once a spacecraft has broken its gravitational bond with Earth, we have other options for powering them. Ion propulsion, long dreamed of in science fiction, is now used to send probes and spacecraft on long journeys through space.

NASA first began researching ion propulsion in the 1950’s. In 1998, ion propulsion was successfully used as the main propulsion system on a spacecraft, powering the Deep Space 1 (DS1) on its mission to the asteroid 9969 Braille and Comet Borrelly. DS1 was designed not only to visit an asteroid and a comet, but to test twelve advanced, high-risk technologies, chief among them the ion propulsion system itself.

Ion propulsion systems generate a tiny amount of thrust. Hold nine quarters in your hand, feel Earth’s gravity pull on them, and you have an idea how little thrust they generate. They can’t be used for launching spacecraft from bodies with strong gravity. Their strength lies in continuing to generate thrust over time. This means that they can achieve very high top speeds. Ion thrusters can propel spacecraft to speeds over 320,000 kp/h (200,000 mph), but they must be in operation for a long time to achieve that speed.

An ion is an atom or a molecule that has either lost or gained an electron, and therefore has an electrical charge. So ionization is the process of giving a charge to an atom or a molecule, by adding or removing electrons. Once charged, an ion will want to move in relation to a magnetic field. That’s at the heart of ion drives. But certain atoms are better suited for this. NASA’s ion drives typically use xenon, an inert gas, because there’s no risk of explosion.

In an ion drive, the xenon isn’t a fuel. It isn’t combusted, and it has no inherent properties that make it useful as a fuel. The energy source for an ion drive has to come from somewhere else. This source can be electricity from solar cells, or electricity generated from decay heat from a nuclear material.

Ions are created by bombarding the xenon gas with high energy electrons. Once charged, these ions are drawn through a pair of electrostatic grids—called lenses—by their charges, and are expelled out of the chamber, producing thrust. This discharge is called the ion beam, and it is again injected with electrons, to neutralize its charge. Here’s a short video showing how ion drives work:

Unlike a traditional chemical rocket, where its thrust is limited by how much fuel it can carry and burn, the thrust generated by an ion drive is only limited by the strength of its electrical source. The amount of propellant a craft can carry, in this case xenon, is a secondary concern. NASA’s Dawn spacecraft used only 10 ounces of xenon propellant—that’s less than a soda can—for 27 hours of operation.

In theory, there is no limit to the strength of the electrical source powering the drive, and work is being done to develop even more powerful ion thrusters than we currently have. In 2012, NASA’s Evolutionary Xenon Thruster (NEXT) operated at 7000w for over 43,000 hours, in comparison to the ion drive on DS1 that used only 2100w. NEXT, and designs that will surpass it in the future, will allow spacecraft to go on extended missions to multiple asteroids, comets, the outer planets, and their moons.

Missions using ion propulsion include NASA’s Dawn mission, the Japanese Hayabusa mission to asteroid 25143 Itokawa, and the upcoming ESA missions Bepicolombo, which will head to Mercury in 2017, and LISA Pathfinder, which will study low frequency gravitational waves.

With the constant improvement in ion propulsion systems, this list will only grow.

Bio-Mimicry and Space Exploration

“Those who are inspired by a model other than Nature, a mistress above all masters, are laboring in vain.”

-Leonardo DaVinci

What DaVinci was talking about, though it wasn’t called it at the time, was biomimicry. Biomimicry is the practice of using designs from the natural world to solve technological and engineering problems. Were he alive today, there’s no doubt that Mr. DaVinci would be a big proponent of biomimicry.

Nature is more fascinating the deeper you look into it. When we look deeply into nature, we’re peering into a laboratory that is over 3 billion years old, where solutions to problems have been implemented, tested, and revised over the course of evolution. That’s why biomimicry is so elegant: on Earth, nature has had more than 3 billion years to solve problems, the same kinds of problems we need to solve to advance in space exploration.

The more powerful our technology gets, the deeper we can see into nature. As greater detail is revealed, more tantalizing solutions to engineering problems present themselves. Scientists who look to nature for solutions to engineering and design problems are reaping the rewards, and are making headway in several areas related to space exploration.

NASAs Ten-Engine Electric Plane

NASA has been grabbing headlines recently with their potentially game-changing emDrive propulsion system. The emDrive has generated a lot of discussion, and a lot of controversy too. But NASA has a lot more going on than futuristic space travel designs, and one recent test flight showed that the minds at NASA are still working on innovative designs for flight systems that operate in Earth’s atmosphere.

The Greased Lightning 10, or GL10, is a remotely piloted, ten engine aircraft that can take off and land vertically, and then rotate its wings for forward flight. This type of system has been developed before in full size, piloted aircraft like the V22 Osprey, but it’s never been done before in a small, remotely-piloted aircraft.

Book Review: How To Build a Universe

We live in a wild and crazy universe. Gigantic stars explode and create the stuff of life, virtual particles pop in and out of existence so fast they can barely be measured, and light exists as particles and waves at the same time. And it all started with three simple words: The Big Bang. It’s taken hundreds of years of science to begin to sort some of this out, so for one author to write one book that tells the whole story is an enormous task.

Enter Ben Gilliland, science columnist, gifted illustrator, and winner of the 2013 Sir Arthur Clarke Award for Space Achievement in Media. Gilliland tackles the task in his new book “How to Build a Universe: from The Big Bang to the End of the Universe.” He uses engaging storytelling, eye-catching graphics, and a relaxed and friendly style of writing that makes reading his book an enjoyable and informative experience.

“How To Build A Universe” reads like a conversation with a knowledgeable and enthusiastic friend. Gilliland leads us through the twists and turns of the story of the universe and uses his skill as an illustrator to great narrative effect. From The Big Bang, to the discovery of the atom. From the point in time when other galaxies will become invisible to observers on Earth, to the eventual death of the universe, it’s all explained with wit and detail.

If you’ve ever picked up a book about space science, opened the first page and then asked yourself why you didn’t take cosmology and astrophysics in university, this book is for you. There’s none of that with Gilliland’s book. This book grabs the reader right away, and is engaging from start to finish.

You would have to take several university level courses in astronomy, astrophysics, and cosmology to cover as much ground as “How To Build A Universe” does in 224 pages. And your professors probably wouldn’t be near as engaging as the author, Ben Gilliland. (You’d go to more parties if you went to university, but that’s another subject.)

Don’t get the wrong idea. This book is not dumbed down. It finds its audience nicely. It touches on all the important topics, and digs into the detail with clarity and humour. The writing is clear and concise at the same time that it’s warm and informal. Beyond the writing, it’s the wealth of thoughtful illustrations that help pull it all together.

I’m a technical writer, and I know how hard it can be to explain complicated subjects to people. Ben Gilliland makes it seem effortless. His explanations of quantum physics are particularly effective, and they’re the clearest explanation of that challenging material that I’ve ever come across. I could say the same thing about how he handles Dark Matter and Dark Energy, two other difficult to explain concepts.

Gilliland is a gifted writer and illustrator, and I highly recommend “How To Build a Universe” to Universe Today readers.

Book Review and Giveaway: The Constellation Observing Atlas

Here is another giveaway just in time for the holidays: The Constellation Observing Atlas by Grant Privett and Kevin Jones. Springer and Universe Today are giving away free copies to two lucky Universe Today readers.

Review by: Evan Gough

The night sky is vast and full of wonders, and binoculars or a telescope can bring these wonders into view. The planets and the moon are easy to find, but after that, the rest of the objects in the night sky can be challenging to locate. “The Constellation Observing Atlas,” by Grant Privett and Kevin Jones, will guide you around the night sky, and help you find the most interesting objects.

This atlas uses the patterns of the constellations to cut the sky up into bite-sized pieces, giving the amateur observer an easy to use method for exploring the night sky. “The Constellation Observing Atlas” has a section for each one of the eighty-eight constellations recognized by the International Astronomical Union, from Andromeda to Vulpecula.

General information about each constellation is included, followed by the history of its name and mapping, any notable double and variable stars are mentioned and any deep sky objects that reside in or near the constellation are listed. Along with some nice images, “The Constellation Observing Atlas” also has detailed maps of each constellation which helps make the observing process straightforward.

The book is well laid out, and the amount of information for each constellation is just right. The maps are detailed and helpful and I found the history sections very interesting and amusing. The authors don’t mind having a little fun at the ancient’s expense for some of their comical constellation choices and the convoluted myths behind them, and who can blame them? Many of the constellations are just vague clumps and arrangements of stars in which the ancients somehow saw their most powerful gods, mythical creatures, and heroes.

Like many Universe Today readers, I’m interested in all things astronomy and space, but I’m far from an expert observer. “The Constellation Observing Atlas” tries to make the night sky accessible for amateurs like myself, and it works. You simply locate a constellation in the sky, check the book for interesting viewing targets, point your ‘scope around, and have some fun. Some of the stars and deep sky objects will be challenging to find, and the authors give detailed information for finding these elusive targets.

In my part of the world, winter has come and I’m in store for some clear, cold, crisp nights. There should be some great observing conditions ahead, with Orion prominent in the night sky. I’m looking forward to using “The Constellation Observing Atlas” to expand my observing. The authors have done a good job of being informative and fun, and I highly recommend this book to amateur and novice observers. It makes the wonders of the night sky accessible, one constellation at a time.

Giveaway: The Shirtsleeve Invention by Gloria Beasley Lauston

I love all things space related. I’m excited by the jaw-dropping images from the Hubble, awed by the Kepler spacecraft’s discoveries, and to be honest, almost moved to tears by the successful landing of the Mars Science Laboratory. As a boy, the Space Shuttle program seemed like science fiction come to life. Behind these peak moments in discovery, there are a lot of people doing a lot of hard work, dedicating their whole lives to solving one problem. One such person is Robert Beasley, the man behind the Thermal Protection tiles used on the Space Shuttle. Robert Beasley was an American chemist who invented and developed the Thermal Protection system for the Space Shuttles which allowed them to re-enter Earth’s atmosphere without burning up.

Universe Today and Bohlsen Group are teaming up to give away 2 free copies of The Shirtsleeve Invention by Gloria Beasley Lausten. Here’s how:

In order to be entered into the giveaway drawing, just put your email address into the box at the bottom of this post (where it says “Enter the Giveaway”) before Friday, September 13, 2013. We’ll send you a confirmation email, so you’ll need to click that to be entered into the drawing.

The Shirtsleeve Invention is the story of Beasley and his idea. The book is a very detailed history of Beasley’s life and career; sometimes a little too detailed. The Shirtsleeve Invention is written by his widow, Gloria Beasley Lausten, who is not a professional writer. At times it is a deeply personal account of her husband. It contains the kind of detail that only a spouse would know, so along with being an account of Beasley’s career, and how his drive and determination helped lead to the development of the Space Shuttle, it also contains lots of detail about his personal life and struggles through childhood, college, and adult life. The book is so personal and full of insight, it’s quite touching at times.

Interviewed after the initial successful flight and re-entry of the Space Shuttle Columbia in 1981, when Beasley’s ceramic tile system did its job and protected Columbia from the 2400 degree heat of re-entry, Bob said to a reporter, “That’s the end of so many years of heartache you can’t imagine. All the heartaches, all the stress, it was worth it.”

The meat of The Shirtsleeve Invention is the account of his idea for the Space Shuttles, and how the idea grew. How he struggled to convince others that his idea was a sound one. It wasn’t always easy, but like things sometimes turn out, his idea proved to be the key for the development of the Space Shuttle and the things that followed. Without the Shuttle Program, there would be no International Space Station and no Hubble Space Telescope. Without Beasley and his creativity and perseverance, who knows where the state of space exploration would be?

This book is a little miscast as a science book. There’s science in there, but for me the book bogged down a little with too much detail about his personal life. There are lots of letters back and forth between him and his relatives and future wife detailing his struggles in school and early working life. The book is realistic; no doubt about that. Without Robert Beasley, and countless others like him, where would the state of human knowledge be? He’s certainly deserving of recognition.

I enjoyed the book, but I found myself skimming over some of the more detailed parts of his private life. Universe Today readers may have a similar experience reading it. But for those of you specifically interested in the lives of people behind the science of space exploration, The Shirtsleeve Invention is for you.

Book Review: The Life and Death of Stars

“The Life and Death of Stars” is a thorough and richly detailed book that will tell you all you want to know about stars. The author, Kenneth R. Lang, is Professor of Astronomy at Tufts University, and he clearly has the knowledge and explanatory ability of someone who has spent his life studying stars. Though its density may deter the casual reader, I found this book engrossing from beginning to end.

If you’ve just been recently bitten by the astronomy bug, this book may not be for you. A more introductory book might be a better choice. But if you’re craving a deeper and more comprehensive understanding of stars, this book will deliver. Make no mistake though; for most readers, it will require some commitment to read your way through this book.

I was never an astrophysics student, but this book seems to me to have a textbook like thoroughness, though not in a dry way. The chapters and topics flow along logically and clearly, with the help of numerous charts and illustrations. For instance, the book starts off with a thorough explanation of light. Since almost all that we know about stars we’ve learned by observing light, where else should a book on astrophysics begin?

From there, the book moves on to chapters titled “Transmutation of the Elements,” “New Stars Arise from the Darkness,” and “Stellar End States,” with other stops in between. The final chapter is titled “Birth, Life, and Death of the Universe.” At the very end of the book, Lang discusses the possible endings of the Universe, and how the mystery of Dark Matter and Dark Energy may dictate the end.

My own understanding of the behaviour and lifecycle of stars has grown enormously from reading this book, and yours will too. For example, if you know that stars form when interstellar gas clouds collapse from their own gravity, but don’t understand exactly how, then “The Life and Death of Stars” will tell you all the detail you’ll need to know. If you know that heavier elements are formed via nucleosynthesis, in the hearts of stars, but you don’t grasp the finer details of that process, then the explanation in this book will bring it to life for you.

Lang is not a populariser of astronomy. His strength is in detailed descriptions, delivered in a comprehensible way. However, he’s not opposed to the occasional poetic turn of phrase: “All stars are impermanent beacons that eventually will cease to shine, vanishing like a circle of fire turning to ash.” True that. He also quotes the Bhagavad Gita, and the poet Shelley.

One of the ways I gauge a book is by my own level of excitement and interest as I’m reading it. I also judge a book by its clarity of explanation and its flow. In both these respects, Lang delivers with this book. After reading it, I’ll definitely be checking out his other books.

“The Life and Death of Stars” broadened and deepened my understanding of all things stellar. It’s a fantastic book, and I wholeheartedly recommend it to Universe Today readers who wish to expand their knowledge of astrophysics.

Book Review: Unraveling the Universe’s Mysteries

“Unraveling the Universe’s Mysteries” is Louis A. Del Monte’s contribution to the world of science writing. If you haven’t heard of him, don’t be surprised. He’s not a prolific author or researcher, but worked in the development of microelectronics for the US companies IBM and Honeywell before forming a high-tech e-marketing agency.

The book lives up to its title and long subtitle: “Explore sciences’ most baffling mysteries, including the Big Bang’s origin, time travel, dark energy, humankind’s fate, and more.” It covers string theory, the Big Bang, dark matter, dark energy, time travel, the existence of God, and other mysterious aspects of our Universe. Del Monte also discusses artificial intelligence, the end of the Universe, and the mysterious nature of light. These subjects have all been covered in great detail by other authors in other books. How does Del Monte’s treatment of these subjects stand up in comparison?

Not great, in my opinion. The writing is somehow uninviting. The book reads more like a textbook or a lecture than it does a science book for an interested audience. It’s somewhat dry, and the writing is kind of heavy. After looking into Del Monte’s background, it becomes clear why. He’s an engineer, and his background is in writing technical papers.

This book is a bit of a puzzle, as is the author himself. I’ve mentioned the problems with the writing, but there are other issues. In one instance Del Monte references a study from the Journal of Cosmology. If you haven’t heard of that journal, it’s come under heavy criticism for its peer-review process, and isn’t highly regarded in science circles. The Journal of Cosmology seems to be a journal for people with an axe to grind around certain issues more than a healthy part of the science journal community. To be quoting studies from it is a bit of a black mark, in my opinion.

In another instance, he opens the chapter on Advanced Aliens with a quote from “Chariot of the Gods”, that old book/documentary from the 1970’s that just won’t seem to die, no matter how discredited it is. The main thrust of “Chariot of the Gods” is that human civilisation got a technological boost from visitations by advanced aliens. Readers can judge for themselves the wisdom of quoting “Chariot of the Gods” in a science book.

The publisher bills the book as “a new theory to explain one of cosmology’s most profound mysteries, the accelerated expansion of the universe,” and that Del Monte “presents an original solution to Einstein’s equations of special relativity.” But without conducting peer reviewed research, the validity of his theory comes into question.

If I seem puzzled by this book, it’s because I am. Del Monte seems to be a bit of an outsider when it comes to writing about astronomy and cosmology. He has no background in it. There’s nothing wrong with that in principle; there’s always room for new perspectives in science. But I can’t help thinking that he could’ve benefited from working more closely with an experienced editor.

Readers will get something out of this book; it’s an interesting discussion of the mysterious aspects of our Universe. But it’s also a somewhat strange book. For those of you who decide to read it, you’re in for an interesting read.
