Did you know that LEO stood for Low Earth Orbit? With 10s of thousands of LEO satellites to be launched in the coming years you want to ensure that the motors you use are designed for the rigors of space; and Kollmorgen knows space. They have been supplying motors to NASA - National Aeronautics and Space Administration programs since the Gemini missions of the mid 1960s and continuing through the Apollo moon landings; the Skylab space station; GPS satellites; Titan rocket guidance systems; the Space Shuttle; the Mars rovers Spirit, Opportunity, Curiosity and Perseverance; and many other missions where failure is not an option. Check out their dedicated space solutions here: https://hubs.la/Q02F_DXQ0 Contact Jeff Fiorini to learn more. [email protected] 813-597-3960 Do you like space?

Probably the last update to my (unofficial) NASA - National Aeronautics and Space Administration Virginia Space Grant Consortium orbit planner; added the ability to lengthen the visible path, and change camera reference frame. As you can see in this video, you can make some crazy orbit-art by fiddling with the values while in ECEF. https://lnkd.in/eDZ2Ubn2

Lovely but after 2 Years, literally Anisotropic interactions in ESR/EPR spectroscopy, such as dipolar couplings and hyperfine interactions, provide detailed information about the local environment of unpaired electrons. Here’s a deeper look at these interactions: ### Anisotropic Interactions in ESR/EPR Spectroscopy 1. **Dipolar Couplings** - **Definition**: Dipolar couplings arise from the magnetic interaction between two unpaired electron spins. This interaction depends on the relative orientation and distance between the spins. - **Dipolar Hamiltonian**: The Hamiltonian describing the dipolar interaction is given by: \[ H_{dip} = \frac{\mu_0}{4\pi} \frac{g_e^2 \mu_B^2}{r^3} \left[ \mathbf{S}_1 \cdot \mathbf{S}_2 - 3 (\mathbf{S}_1 \cdot \hat{\mathbf{r}})(\mathbf{S}_2 \cdot \hat{\mathbf{r}}) \right] \] where \(\mathbf{S}_1\) and \(\mathbf{S}_2\) are the spin operators of the two electrons, \(r\) is the distance between them, and \(\hat{\mathbf{r}}\) is the unit vector along the line connecting them. - **Information Provided**: The dipolar coupling constant provides information about the distance between the unpaired electrons. Since this interaction is orientation-dependent, rotating the sample in the magnetic field can reveal the spatial arrangement of the spins. 2. **Hyperfine Interactions** - **Definition**: Hyperfine interactions occur between the magnetic moments of unpaired electrons and nearby nuclear spins. These interactions can be isotropic or anisotropic, depending on the spatial distribution of the electron cloud around the nucleus. - **Hyperfine Hamiltonian**: The Hamiltonian for the hyperfine interaction is: \[ H_{hf} = \mathbf{S} \cdot \mathbf{A} \cdot \mathbf{I} \] where \(\mathbf{S}\) is the electron spin operator, \(\mathbf{I}\) is the nuclear spin operator, and \(\mathbf{A}\) is the hyperfine coupling tensor. - **Isotropic Hyperfine Interaction**: This interaction, also known as the Fermi contact interaction, arises from the overlap of the electron cloud with the nucleus. It is described by a scalar coupling constant \(A_{iso}\). \[ H_{iso} = A_{iso} \mathbf{S} \cdot \mathbf{I} \] - **Anisotropic Hyperfine Interaction**: This interaction results from the electron’s orbital motion and is described by a tensor. It provides information about the orientation of the electron cloud relative to the nucleus. \[ H_{aniso} = \mathbf{S} \cdot \mathbf{A} \cdot \mathbf{I} - A_{iso} \mathbf{S} \cdot \mathbf{I} \] - **Information Provided**: Hyperfine interactions give insights into the electronic environment around the nucleus, including the electron density distribution and the nature of bonding. The anisotropic part reveals the spatial orientation of the electron cloud.
Watch as the second fully integrated core stage for NASA - National Aeronautics and Space Administration’s Space Launch System rocket rolls out of NASA’s Michoud Assembly Facility. The core stage is headed to the Vehicle Assembly Building at NASA’s Kennedy Space Center for final assembly and testing. Stay tuned for more progress on the road to #Artemis II, which will transport four astronauts around the Moon.
