Rippling fusion crust preserved across half the surface

This 36.92g individual preserves approximately 50% original fusion crust across its edges, showing the rippled texture characteristic of atmospheric entry heating. One face has been sanded to reveal the internal brecciated structure, a mosaic of light eucritic fragments and darker diogenitic material locked in a fine-grained matrix. The contrast between the black glassy fusion crust and the exposed interior brecciation makes this specimen particularly effective for display and study.

Classified in 2024 from a find in Mali, this howardite represents impact-mixed material from the surface of asteroid 4 Vesta. The specimen displays clear lithologic boundaries between clast types, demonstrating the violent impact processes that created the howardite regolith breccia on Vesta's crust.

Brecciated texture reveals impact mixing

The sanded face exposes angular clasts of contrasting composition embedded throughout the matrix. Eucritic fragments appear lighter in tone, while diogenitic material shows darker grays. This heterogeneous texture formed when asteroidal impacts on Vesta's surface excavated and mixed material from both the basaltic crust (eucrites) and the deeper orthopyroxene-rich cumulates (diogenites), then lithified the mixture through subsequent impact compression.

The fusion crust exhibits the glossy black appearance and flow textures typical of atmospheric ablation. These surface features formed during the meteorite's deceleration through Earth's atmosphere, when frictional heating melted the outer layer into glass. The preservation of roughly half the original crust indicates minimal terrestrial weathering since the fall.

Scientific context: asteroid Vesta's impact history

Howardites belong to the HED achondrite group, howardites, eucrites, and diogenites, all confirmed by NASA's Dawn mission spacecraft data to originate from asteroid 4 Vesta, the second-largest object in the asteroid belt. Vesta is one of only a few asteroids large enough to have differentiated into a core, mantle, and crust during the early solar system. Eucrites represent Vesta's basaltic crust, diogenites come from the deeper orthopyroxenite cumulate layers, and howardites are impact breccias mixing both lithologies.

The brecciated nature of howardites records Vesta's violent collisional history. Large impacts fractured and excavated material from different crustal depths, mixed the fragments, then compacted them into coherent breccias through subsequent impacts. Study of howardites provides direct evidence of impact gardening processes on differentiated asteroids.

Frequently asked questions

Is this meteorite authenticated? NWA 17708 is officially classified as a howardite in the Meteoritical Bulletin Database. You can verify the classification here: NWA 17708. This specimen includes a certificate of authenticity from Treasure Coast Meteorite Co. documenting its classification, weight, and provenance.

What does howardite mean? Howardites are polymict breccias, rocks composed of fragments from multiple source materials, containing both eucritic (basaltic) and diogenitic (orthopyroxenite) clasts from different depths within asteroid Vesta's crust. The mixing occurred through impact processes on Vesta's surface. Howardites are rarer than eucrites and diogenites individually.

What is included with this specimen? The listing includes the 36.92g NWA 17708 individual, certificate of authenticity from Treasure Coast Meteorite Co., custom specimen card with classification details, and protective gembox display case.

How do howardites differ from eucrites? Eucrites are monomict basaltic achondrites representing Vesta's volcanic crust, while howardites are polymict impact breccias containing clasts of both eucrite and diogenite mixed together. Howardites typically show visible heterogeneity with contrasting clast types in a single specimen, whereas eucrites display more uniform basaltic texture.

Why is the fusion crust significant? Fusion crust forms only during atmospheric entry and degrades rapidly through weathering in most terrestrial environments. The preservation of approximately 50% original crust on this specimen indicates minimal time on the ground before recovery and suggests the find occurred in an arid environment favorable for meteorite preservation.

Display-ready specimen documenting Vesta's impact history

At 36.92g, this individual provides substantial mass for both display and study. The combination of preserved fusion crust and exposed brecciated interior in a single specimen allows direct comparison of surface and internal features. The sanded face clearly shows the polymict texture that defines howardites, while the fusion crust documents the specimen's journey through Earth's atmosphere.

Howardites represent less than 15% of witnessed falls among the HED achondrite group, making them significantly less common than eucrites. This specimen's fresh appearance and dual-feature presentation, both exterior crust and interior texture visible, makes it particularly suitable for educational collections and institutions. The 2024 classification provides modern analytical data and documentation. Explore more specimens from asteroid Vesta in our HED Meteorites collection.

A welcome inoculation to today's bleak outlook on our bodies
Format: Hardcover
Book Review: Love Thy Body: Answering Hard Questions about Life and Sexuality Author: Nancy R. Pearcy Format: Hardback Topic: Christian Thought and Culture Scope: Contemporary Living and Influence in the Culture Purpose: To equip Christian leaders, parents, and students with the tools to know about the "why" and "how" about the current cultures' view on topics concerning our bodies. Structure: The book has an introduction, 7 chapters, and a study guide. 1. I Hate Me: The Rise and Decline of the Human Body (We have inadvertently accepted a flawed view of the body as less real and of less worth than it is in reality) 2. The Joy of Death: "You Must Be Prepared to Kill" (The desire to liberate women from reproduction is based on faulty, dehumanizing reasoning) 3. Dear Valued Constituent: You No Longer Qualify As a Person (When we hold the body as of little value, no one is safe against the dehumanizing effect) 4. Schizoid Sex: Hijacked by the Hookup Culture (Contrary to popular belief the sexual revolution doesn't value the body enough) 5. The Body Impolitic: How the Homosexual Narrative Demeans the Body (When feelings and desires rule our actions and beliefs we deny the more objective grounding of biology to tell us who we are and how we should live) 6. Transgender, Transreality: "God Should Have Made Me a Girl" (Encouraging gender dysphoria and sex changes flies in the face of the objective facts of biology to the detriment of human persons) 7. The Goddess of Choice is Dead: From Social Contract to Social Meltdown (The foundations of the major institutions of society have shifted from biology to social contract) What it does well: *Pearcey is fantastic at making hard material accessible to all audiences. While much of the information in this book could be very academic, Pearcey has gathered scores of illustrations and stories to drive the harder points home. *In every chapter, Pearcey compares and contrasts the current secular view of the body with the biblical view of the body. She shows how the Christian view of the body is more freeing and more complete than our current view. *Similarly, Pearcey also shows how the Christian view is more objective and values the person more highly. *Pearcey clearly shows that often women and children are demeaned and dehumanized through the very ideas and practices meant to free them. This is a huge contention in our society and Pearcey's voice fills a huge need here. *Another thing the book does well is to show how the ideals of the homosexual and transgender movement are really enslaving people to unhealthy gender stereotypes. Instead, if masculinity or feminity is rooted in the unchanging root of biology then we can engage in a whole host of activities without threatening our gender or sexuality *Probably the best part of this book is how deeply Pearcey's love for individual people comes through as she is critiquing some of their most cherished beliefs. What it lacks: *While Pearcey's cultural analysis is fantastic, her philosophy is not quite as steller. I wondered throughout if she had oversimplified some thinkers and seen connections to today's problem that are not necessarily there. I did find that some others (who have more expertise in the area than I) thought similarly: http://www.patheos.com/blogs/eidos/2018/01/love-thy-body-nancy-pearceys-book-brilliant-flawed/?repeat=w3tc . This doesn't harm the overall message of the book, but instead just makes it clunky and a little confusing at points. *While this book was a great hybrid of academic and popular work, I am not partial to the choice for endnotes rather than footnotes. Many publishers choose endnotes in popular works because the reader need not be distracted by the trivia and citing that goes on and I understand that. However, footnotes are much better for those of us who want to seek out sources or understand the material in more depth. That being said, this criticism is cosmetic. Some quick highlights: "My goal in Love Thy Body is to show that a secular morality 'doesn't fit the real universe.'"-11 On fetuses developing into persons: "But there is no scientific evidence of such a transformation--no single, dramatic turning point that can be empirically detected. Embryonic development is a continuous process, gradually unfolding the potentials that were built in from the beginning."-25 "We tend to think sexual hedonism places too much value on the purely physical dimension. But in reality it places a very low value on the body, draining it of moral and personal significance. In the hookup culture, partners are referred to as 'friends with benefits.' But that is a euphemism because they are not really even friends. The unwritten etiquette is that you never meet just to talk or spend time together."-28 "Scripture treats body and soul as two sides of the same coin. The inner life of the soul is expressed through the outer life of the body."-34 "It is true that at death, humans undergo a temporary splitting of body and soul, but that was not God's original intent. Death rips apart what God intended to be unified."-37-38 "The core question in abortion, then, is the status of the human body."-52 "For that matter, even fully developed adults have these traits in varying degrees. When I meet someone who is more intelligent than I am, does that mean they are more of a person than I am--and should have more rights than I have?"-53 "A Christian concept of personhood depends not on what I can do but on who I am--that I am created in the image of God, and that God has called me into existence and continues to know and love me. Human beings do not need to earn the right to be treated as creatures of great value. Our dignity is intrinsic, rooted in the fact that God made us, knows us, and loves us."-55 "The early Christians went beyond simply condemning abortion to providing alternatives--rescuing and adopting children who had been abandoned."-70 "A culture that respects women's bodies will create more flexible career trajectories that allow women to have their families at the time that is biologically optimal. It will create education and work patterns that fit around family responsibilities. When we do that, we will reduce a major motive for abortion."-76 "When human life is no longer seen to have inherent value, it will be subject to purely utilitarian calculation of costs and benefits. Voluntary euthanasia may not remain voluntary."-91 "A fundamental principle of ethics is that people should be treated as intrinsically valuable, not valuable only as a means to some extrinsic end. Or as we say in ordinary conversation, it is wrong to use people."-94-95 "Though evil is still evil, the wonder is that God is greater and can turn it to good."-109 "Today's hookup culture glamorizes impersonal sex but gives no clue how to start a real relationship."-117 "From childhood, young people are awash in sexual imagery, but sexual intimacy is increasingly difficult to achieve."-125 "In a culture that says we have a right to the pleasures of sex, while denying its biological function, many will end up treating babies as the enemy--intruding where they are not wanted or welcome."--150 "Though our feelings are important, Doherty concluded, they are not what define our identity. Nor are they a reliable guide to God's purposes. Because we are fallen and sinful, our feelings fluctuate over time. The most reliable marker of who we are is our physically embodied, God-given identity as male and female."-156 "You cannot be a whole person when your emotions are at war with your physiology."-173 "Our feelings do not define us. Our moral commitments do. We find fulfillment when we find ways to live in congruence with our deepest commitments."-180 "The early church may have been 'on the wrong side of history.' But that's why it changed history."-188 "...you can engage in a range of diverse behaviors without threatening the security of your identity as a man or woman."-198 "The church should be the first place where young people can find freedom from unbiblical stereotypes."-218 "Once a person is convinced that Christianity is true, then they can ask what that means for their sexuality. And only then will they have the spiritual strength and resources to find solutions to their sexual issues."-260 Recommendation?: I highly recommend this book. It is highly needed at this point in our culture. It is a rallying cry to love people with the truth. I especially hope churches start to strategically think through these issues to become havens for those who hurt and are confused.

Love Thy Body
Format: Kindle
The publication of Nancy Pearcey’s book, Total Truth: Liberating Christianity From Its Cultural Captivity sent shockwaves throughout the evangelical world and help equip a new generation of apologists. Total Truth confronted the notion that scientific knowledge and moral knowledge were separated into two domains. The lower story includes objective truths that are public and valid for all people. This is the realm of empirical science. These truths are true and verifiable. The upper story includes the realm of moral knowledge which is private, relative, and subjective. Hence, the so-called unified concept of truth was obliterated and separated into two domains. Pearcey’s subsequent works, Saving Leonardo: A Call to Resist the Secular Assault on Mind, Morals, and Meaning and Finding Truth: 5 Principles for Unmasking Atheism, Secularism, and Other God Substitutes have also left an indelible mark on the church and culture at large. The impact of these books on me personally, cannot be overstated. My suspicion is that many people would concur. Nancy Pearcey’s newest offering, Love Thy Body: Answering Hard Questions about Life and Sexuality pick up where the other titles left off. The overarching goal of Love Thy Body is to “uncover the worldview that drives the secular ethic.” Ultimately, the book is designed to “show that a secular morality doesn’t fit the real universe.” Readers familiar with Pearcey will quickly see the influence of Francis Schaeffer on her thought. It was Schaeffer who originally exposed the so-called “fact/value” split which has created a fracture epistemology that continues to be propagated today. Pearcey shows the practical outgrowth of this fragmented worldview (or the two-story worldview) by pointing to several contemporary culture matters including abortion, euthanasia, “same-sex marriage,” and transgenderism. She helps readers understand how these various worldviews have been smuggled into our culture and links each of them to the two-story dichotomy. Readers will be encouraged and challenged to walk through the argument of Love Thy Body and will be better equipped to not only contend with culture but also reach out to people who have been deceived by a pagan worldview. Readers will discover that Pearcey’s argument is not combative. Rather, her heart cries for people who have been co-opted by this deviant worldview. She pleads with readers to reach out and love people with Christ-centered love: “Christians must present biblical morality in a way that reveals the beauty of the biblical view of the human person so that people actually want it to be true.” Love Thy Body is a book that is filled with description and prescription. Facts and figures run through the book but the author is not content to leave her readers with data alone. She sets forth a workable prescription which is set on helping people and healing them at the deepest level. Therefore, “We must work to educate and persuade on a worldview level,” writes Pearcey. Such an approach is imperative if Christ-followers have any hope of reaching a lost world with the saving message of the gospel. Running through the book is a mindset that Pearcey, no doubt, learned from Schaeffer, namely, sharing the gospel with a tear in one’s eye. Love Thy Body is riveting, challenging, educational, a shot to the heart, a challenge for the mind, and bold push for the feet. It will spark controversy in some venues and may even precipitate debate in the local church. Surely, this kind of debate is necessary as Christians seek to influence culture for God’s glory. I received this book free from the publisher. I was not required to write a positive review.

Getting past the noise to a holistic view of the person
Format: Hardcover
In order to have effective conversations about difficult and controversial subjects such as abortion, euthanasia, and sexual ethics it is important for both parties to be on the same page. Otherwise, it is easy to make assumptions about the other person’s motives and end up talking past each other. Discussions turn into arguments where name calling and personal attacks are more common than a reasoned and thoughtful exchange of ideas. In my own experience, it has been difficult to speak up about many of these types of sensitive subjects in public because of fear that I will be labeled intolerant or bigoted. In fact, it appears our culture, as a whole, has descended into a shouting match where the loudest voice is either the secular one screaming about trigger words and safe spaces where no one can challenge your views, or a caricature of Christianity which writes off everyone who disagrees as a hopeless reprobate who is going to hell. In this cacophony, the Christian message of God’s redeeming love for humanity is drowned out in a sea of empty words. Voices shouting past one another, convincing only those who already agree with us. This situation that many Christians find themselves in, unable or unwilling to speak for fear of being attacked and shouted down is why the new book by Nancy Pearcey Love Thy Body is so important. I have been blessed to be part of both the manuscript review and the book launch team for this amazing book and I have to say that this may be one of the most important books for all Christians to read, especially those who wish to be more effective in the public sphere. Over the course of seven very accessible chapters she addresses the most pertinent issues of our times, from abortion, and assisted suicide to the hook up culture and the LGBTQ movement which is sweeping our nation and exposes a fatal flaw in the secular narrative. This flaw that runs through all of these issues is a fractured view of the person which splits apart the body and the mind. What results is a negative view of the body which tramples on human rights and dignity. The secular narrative is that the Christian view of the person is repressive and prudish, often denigrating the authentic self. They want to claim the high moral ground because their view is based on love and acceptance. Nancy’s book gives us the tools to get past the walls and barriers built up by secular buzz words such as “death with dignity,” “marriage equality,” and “pride” to the underlying worldview so we can be on the same page as those we are speaking with. In her words: “As we face the social ills of our own day, we must move beyond denunciations that can sound harsh, angry, or judgmental and instead work to show that the biblical ethic is based on a positive view of the body as part of the image of God.”

Clear thinking on contemporary confusion about our bodies.
Format: Hardcover
We live in a sound-bite society. A 30-second commercial exceeds our attention span unless it is cute, provocative, catchy or unusually funny. Many cannot sustain a thought longer than the time it takes to breathe. Our convictions are strong, they are popular, but they are typically backed by only a thin layer of thought. How can so many be wrong? I will go with the flow of the cultural consensus. As a new Christian, I read “The Christian Mind,” by Harry Blamires. It convinced me that Christians should think. Perhaps true Christianity begins as an admission of sin and an experience of the love and grace of God that we call conversion, but that is only the beginning. We are welcomed into a new found wealth of wisdom for living in God’s world. Growing holiness is the long, slow and sometimes painful journey back to Eden and the way things were meant to be. The Christian life involves the mind and living by revealed convictions. Yet, almost everyone in our culture today lives by a set of convictions of their own. They live by a set of self-discovered rules, ultimate convictions about life, love and the way things are supposed to be. They construct their own ethics out of these convictions. This ethic is fiercely held and savagely defended, but the foundation is very thin. The culture wars are fought on the worldview battlefield. It is the ethics behind the conviction and the thinking behind the thought that needs to be examined, challenged and ultimately changed. When we confront a non-Christian with the holes in their worldview; when we apply thought and fact and truth and history to their ultimate convictions we are shouted down with angry rhetoric. The thinking behind most practical worldviews is paper thin and ill-founded. And when the law of unintended consequences bites them they do not know why. We need to show them why. Christian apologetics is the intentional deprivation of another’s ‘God-Suppressor.” They know God, but they suppress that truth down because of their independent ethic and their perceived freedom in sin. Yet, it is God’s world and his rules apply. Reality bites and apologists show them why. Nancy Pearcey is a worldview apologist. Christians ought to live by a set of revealed convictions about God and man and truth and law and ethics. We are radically different from the world around us because we grow, like plants, out of another kind of fertilizer. We are nourished by divine wisdom. All the treasures of wisdom and knowledge are in Christ. (Colossians 2:3) In many ways, I cut my spiritual teeth on the writings of Francis Schaeffer. Through him, I learned to think like a Christian, and that the Christian need not be ashamed of his intellectual heritage. Now that my teeth are cut, I brush them with Nancy Pearcey writings. She is the echo of Schaeffer updated and applied to the modern world that Schaeffer prophetically warned us about. Her latest book, "Love Thy Body", applies the Christian mind to contemporary issues regarding our bodies. (Abortion, infanticide, euthanasia, transgenderism, stem-cell research, sex, marriage, and homosexuality.) It shows how to understand the thinking of the modern world and apply logic, fact, research, from a Christian mind to the hot-button issues of the day. It is a book that you really should read. It will make you think; like a Christian.

One of my all time faves and most-recommended books
Format: Paperback
I've read and re-read this book, shared with my spouse and children, and we collectively have purchased several copies with the intent to share. The author is incredibly educated, clear and concise, and spiritually gifted. She introduces revolutionary ways of looking at things that seem so obvious when she lays the scriptural groundwork you're probably already familiar with. It's like a combo of "yeah, DUH!!!" along with "HOW did I never see this??" In todays world with so many personal conflicts and confusing issues, Nancy will sharpen your understanding and resolve, and give you the tools to hold valuable and productive conversations with your loved ones. We are now branching out to other book in her repertoire and finding them similarly ground-breaking.
