The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology. [ 1 ] [ 2 ] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and ...
A phenomenological definition of the NOE in nuclear magnetic resonance spectroscopy (NMR) is the change in the integrated intensity (positive or negative) of one NMR resonance that occurs when another is saturated by irradiation with an RF field. The change in resonance intensity of a nucleus is a consequence of the nucleus being close in space ...
Space Automated Bioproduct Lab (SABL): can be used for experiments in the life, physical and material sciences with a focus on supporting research of biological systems and processes. [21] Microorganisms, small organisms, animal cells, tissue cultures, and small plants are studied in this lab.
In magnetic resonance imaging (MRI) and nuclear magnetic resonance spectroscopy (NMR), an observable nuclear spin polarization (magnetization) is created by a homogeneous magnetic field. This field makes the magnetic dipole moments of the sample precess at the resonance frequency of the nuclei. At thermal equilibrium, nuclear spins precess ...
3D and 4D experiments can also be done, sometimes by running the pulse sequences from two or three 2D experiments in series. Many of the commonly used 3D experiments, however, are triple resonance experiments; examples include the HNCA and HNCOCA experiments, which are often used in protein NMR.
In FY2018 alone, two new research platforms, four patents and 17 research articles have been enabled by the National Lab. There are 14 research platforms [ 11 ] on the ISS that have been implemented. The National Lab is the only NASA-funded, non-NASA asset that has sufficient experience to immediately up-scale its level of activity to ...
After exposure in space, MISSE is retrieved in the same manner as it was deployed, the material samples are tested to see if they still have the unique properties needed to complete space missions. MISSEs have active and passive detectors to give a time-history reading, or a reading of what happened to the materials at certain points in time.
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.
