<div dir="ltr"><div>ASTRA LLC (Atmospheric & Space Technology Research Associates LLC) has an opening for a research scientist in Ionospheric and Thermospheric physics. Applicants are sought to assist in the development of a data assimilation model of the global thermosphere and ionosphere based on Kalman Filter and other techniques. The specific areas of interest include global thermosphere-ionosphere models for satellite drag, ionosphere-thermosphere specification and forecast models, high-latitude electrodynamics models, and data assimilation. The work involves participation in several new programs that include scientific research, model development, real-time data assimilation, validation, and operational product development. The hire will also participate in writing reports and proposals. Candidates should have a Ph.D. degree or equivalent work experience in space physics, mathematics, or a related field and preferably experience with FORTRAN and C programming in a UNIX environment. </div><div><br></div><div>ASTRA is a small business with over 12 years of proven experience in research and development work. Our interests include first principles modeling, data assimilation, ground-based and space based instrument development, and Cubesats, mostly focused towards the understanding and specification of the ionosphere-thermosphere system, and space weather. ASTRA has devoted a significant effort in developing real-time data assimilation techniques for the global terrestrial ionosphere and thermosphere as well as in the development, deployment and operation of ground-based and space-based ionospheric monitoring systems. </div><div><br></div><div>Candidates should be strongly motivated and should be interested in learning and developing new technologies. Applications from postdocs as well as experienced scientists and engineers (Ph. D and MS levels) with broad-based experience and the ability to manage sophisticated R & D would also be welcome. ASTRA provides excellent salary and benefits and offers a growth oriented R & D environment. </div><div><br></div><div>Candidates should submit a resume that includes education, experience, publications, research background, list of funded proposals if applicable, and two references to:</div><div><br></div><div>Geoff Crowley</div><div>ASTRA LLC</div><div>5777 Central Avenue, Suite 221</div><div>Boulder, CO 80301</div><div>Phone: 210-834-3475</div><div>E-mail: <a href="mailto:gcrowley@astraspace.net">gcrowley@astraspace.net</a></div><div><br></div><div><br></div><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div style="font-size:12.8px;font-family:arial"><span style="color:rgb(54,95,145);font-family:Calibri"><b><font size="2">Geoff Crowley, Ph.D.</font></b></span><br></div><div style="font-size:12.8px;font-family:arial"><div style="font-family:Helvetica;margin:0in 0in 0.0001pt;font-size:11pt"><span style="color:rgb(54,95,145);font-family:Calibri;font-size:13px">President | Chief Scientist</span></div><div style="font-family:Helvetica;margin:0in 0in 0.0001pt;font-size:11pt"><span style="color:rgb(54,95,145);font-family:Calibri;font-size:13px"><br></span></div><div style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><b><font size="2" color="#365f91" face="Tahoma"><span style="font-size:11pt;font-family:Tahoma,sans-serif">ASTRA, LLC<u></u><u></u></span></font></b></div><div style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><font size="2" color="#365f91" face="Calibri"><span style="font-size:10pt">5777 Central Avenue, Suite 221 | Boulder, CO 80301<u></u><u></u></span></font></div><div style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><font size="2" color="#365f91" face="Calibri"><span style="font-size:13px">Office <a href="tel:%28303%29%20993-8039" value="+13039938039" style="color:rgb(17,85,204)" target="_blank">(303) 993-8039</a> | Cell <a href="tel:%28210%29%20834-3475" value="+12108343475" style="color:rgb(17,85,204)" target="_blank">(210) 834-3475</a> |</span><span style="font-size:10pt"> Fax <a href="tel:%28303%29%20993-8679" value="+13039938679" style="color:rgb(17,85,204)" target="_blank">(303) 993-8679</a></span></font></div></div></div></div></div></div></div>
