Can we (and should we) pursue everything we can dream of? 😉 I can easily envision a Prime Video TV series spun out from Fallout based on this concept! I know the topic of Mars exploration irritates some of us, but I really appreciate the creativity some of our brightest minds are investing in imagining how this could work! NASA and other organizations have been exploring innovative concepts for Martian habitats that leverage both Martian soil and inflatable structures. One approach involves using 3D printing technology to create structures from Martian soil, or "regolith," which shield against radiation and provide structural support. This method, known as "Marscrete" production, involves mixing Martian soil with binders to create a concrete-like material suitable for building habitats. Another concept focuses on inflatable habitats, which offer significant advantages in terms of transport and deployment from Earth to Mars. These habitats can be compactly packed for launch and then expanded to provide spacious living areas once on Mars. They are designed to be covered with regolith for added protection against radiation and to maintain internal pressure. Combining these technologies, some proposals envision habitats with inflatable structures reinforced by 3D-printed walls using Martian soil, offering a hybrid solution that maximizes the benefits of both approaches.

My Student Manvi Just Launched Her Own Space Mission (Almost)! Last Weekend, one of my students, Manvi, invented her space mission practically. Now, you know there is no greater pleasure than seeing a student grow, and let me introduce you to Manvi from my Junior Tech Innovators Program 10xTechClub Manvi is blooming like a supernova! Implementing the program, this brilliant young lady went further to excel in ways that we could never have expected. Who would have thought that a leftover 3D printing filament is sufficient to create an exquisite space rover? You guessed it right, it was Manvi! This is not just an impressive and inventive endeavor but proof of her capacity to transform dreams into tangible work. But wait, there's more! Instead of reading a pre-rehearsed and pre-planned script from start to finish, Manvi was prompted to share a story of her creative journey as she experienced it, in real-time, with no record, take two. Talk about impressive! Manvi, it is fantastic to be your Mentor and to witness the terrific amount of effort that you put into your practice. You are truly a role model for others to emulate, demonstrating how a spoonful of sugar and a dose of programming can transform waste materials into the basic ingredients for the life you want to lead. Of course, I would like to thank Eeshan Prabhu for developing such an artistic and positive classroom environment for Manvi to develop in. This is just the beginning, Manvi. Never stop aiming high because, with your ability and motivational desire, even scraps can build a masterpiece. I'm looking forward to what other wonderful innovations we can develop in the future. #proudteacher #futureengineer #studentsuccess #dreambigger

What #3dprinting material is best for space? That is a harder question. There are a lot of variables for space. But, one really good option is Antero 840CN03. The CN stands for Carbon Nanotubes. Which if you keep up on your comic books and science news, are stronger than spider silk - or steel. Plus, it is a PEKK family plastic that can stand a lot of temperature ranges, and probably one of the most important features - especially if you know your space history - is electrostatic dissipative. (no more Apollo 1, or 13s).

Good news. In this historical day, of sept 7th of 2024 I want to share AMAZING NEWS that will change everything! For the project SIRIUS SPACE , the Principal of my School Unit got R$40,000 to invest in the transformation of a classroom to install Laser cutting machine, CNC milling, 3D Resin Printer ( technology only a little more than a decade on the market), wielding and more wide table for 8 students each, 2 tables total in the class. Arguing now for include a newtonian reflector telescope. All this to build _in loco_ our own technology, since satellites, rovers, drones, hoovers, landers, communication ground -base and space-bases. Small in scale, big in realization and when they got in the High School or University became space engineers, software engineers, designers, architects and artists to use their power of vision to bring the future as movies, paintings, musics and technologies.

I am delighted to share that my latest paper has been published in Nature today 😀. In this paper, we found that rhinoceros beetles can employ their forewings called elytra and flapping forces to passively deploy the hindwings for flight, and use the elytra to push them back to rest, rather than relying on a distinct group of thoracic muscles. By translating the principle of passive mechanism into flapping-wing robots, we demonstrated for the first time that our 18-gram flapping robot - unlike existing flapping robots that keep their wings fixed in a fully extended configuration - can passively deploy its wings to take off and perform stable flight, and rapidly retract the wings against the body upon landing without the need for additional actuators.

🚀 🚁 👽 Efficient Airfoil Design for Martian Flight 🚀 🚁 👽 I would like to share our research on "Airfoil Optimization for Rotors Operating in the Ultra-Low Reynolds Number Regime" published in Physics of Fluids. This research was performed in collaboration with my former BSc student Luigi Renzulli and my supervisor Domenic D'Ambrosio at the Department of Mechanical and Aerospace Engineering at Politecnico di Torino. Our study focuses on the aerodynamics of airfoils operating under ultra-low Reynolds number conditions, similar to those found in the Martian atmosphere. We optimize rounded leading-edge airfoils using Xfoil and then convert these geometries into sharp leading-edge airfoils with appropriate slicing. 📈 Highlights: - Initial design with XFOIL, followed by compressible Navier-Stokes simulations to capture the unsteady vortex shedding present on the airfoil suction side at moderate angles of attack. - Over 10% aerodynamic efficiency boost with sharp leading-edge airfoils due to the formation of laminar separation bubbles (LSBs). - Aerodynamic efficiency for a given lift coefficient is not degraded for lower angles of attack where the separation bubble is not present. The video illustrates how, under specific conditions, a pulsating separation bubble forms near the leading edge, emitting vortices that stay close to the airfoil's suction side. The low-pressure cores of these vortices create a high-lift regime, that combined with reduced shear drag from the separation bubble, significantly enhance the efficiency of these airfoils. This regime is not exclusively found in sharp leading-edge geometries, but the likelihood and the range of angles of attack for which is found are favored by the geometrical separation at the leading edge.

⚡Color Coding Vortices – Flapping Wing Propulsion 🎨 While aeroplanes rely on the steady motion of a wing to generate aerodynamic forces, animals use more intricate motions to propel themselves through fluids, both during swimming and flying. The flapping motions cause the surrounding air or water to swirl around the edges of the wing or fin, and manipulating these vortices is important for the forces generated. Of course, the flows around bird wings and fish fins are usually invisible to us, so we mimicked these types of motions in the laboratory and devised a way to fluorescently colour code the water flows created by a 3D-printed wing. The results from these experiments are shown in these videos, where one sees a beautiful dance between the red vortices generated at the front and the green ones generated at the back. 🌎 Source: https://lnkd.in/etnyXbUm 📥 Science News: https://lnkd.in/d7B7fqA #engineeredmind #science #technology #engineering #mechanicalengineering #physics #mathematics

Excited to share our new paper in Ocean and Coastal Research Journal, with Florian Meirer and Erik van Sebille! "Identifying the Origins of Nanoplastics in the Abyssal South Atlantic Using Backtracking Lagrangian Simulations with Fragmentation" 🌊 The presence of nanoplastics (plastic particles smaller than 1 micrometer) in the deep ocean presented a puzzle: their colloidal properties (they don't sink or float as microplastics) mean they'd need centuries to reach the abyssal South Atlantic Ocean (deeper than 4000m) through ocean circulation alone. Using 3D Lagrangian backtracking simulations, our study suggests that these particles likely entered the ocean as larger pieces and fragmented during their descent into the deep ocean. This highlights the crucial role of fragmentation in understanding the origin of nanoplastics in the deep ocean. By tracking particles backwards in time from 5000m depth to their possible surface origins, we found that nanoplastics couldn't have reached these depths as-is within our 13-year simulation window. Instead, their presence likely results from larger particles fragmenting during their descent – a process that influences both their sinking velocity and drift patterns. 💎 Full article available through Diamond Open Access (no fees for readers or authors): https://lnkd.in/eJtZEWnH #MarineScience #Oceanography #PlasticPollution #Research The animation shows a backward-in-time simulation of PET nanoplastics from 5000 meters deep in the South Atlantic Ocean. The blue scale shows the sea surface height of the ocean to represent the circulation patterns at the surface, although the particles are moving in the ocean interior. The particle color shows the depth of particles.
