This led them to an absorption with the Jewish creation myths in Genesis, which they obsessively reinterpreted to formulate allegorical explanations of how humans ended up trapped in the world of matter. The basic Gnostic story, which varied in details from teacher to teacher, was this: In the beginning there was an unknowable, immaterial, and invisible God, sometimes called the Father of All and sometimes by other names. “He” was neither male nor female, and was composed of an implicitly finite amount of a living nonphysical substance. Surrounding this God was a great empty region called the Pleroma (the fullness). Beyond the Pleroma lay empty space. The God acted to fill the Pleroma through a series of emanations, a squeezing off of small portions of his/its nonphysical energetic divine material. In most accounts there are thirty emanations in fifteen complementary pairs, each getting slightly less of the divine material and therefore being slightly weaker. The emanations are called Aeons (eternities) and are mostly named personifications in Greek of abstract ideas.

  • Project Argonaut: a Proposal for a Mars Sample Return Mission ∗
    Project Argonaut: A Proposal for a Mars Sample Return Mission ∗ Archit Arora, Courtney Best, Liam Durbin, Robert Groome, Duncan Harris, Henry Heim, Thomas Keane, Eric Miller, Annie Ping, and Alexandra Wyatt Purdue University, West Lafayette, Indiana, 47906, United States With increasing interest in colonizing Mars, multiple missions have been aimed at re- trieving more information about the red planet, such as the recent Mars Science Laboratory mission. The main focus of this interest is in determining whether Mars is capable of sup- porting life, which requires an analysis of the soil. The next major step in Martian science is a Mars Sample Return mission, which would allow scientists to conduct complicated and in-depth tests on the soil that are not possible with robotic instruments sent to Mars. This paper explores Project Argonaut, a mission proposal to retrieve a sample from the surface of Mars and bring it back to Earth. The name Argonaut reflects the legend of the band of heroes who sailed on the Argo to fetch the golden fleece from the field of Ares, as the mis- sion requires a journey to Mars in order to retrieve the prized sample. Project Argonaut integrates existing research with innovative concepts to propose a plausible solution to the key issues associated with the mission. ∗Copyright c 2016 by Archit Arora, Courtney Best, Liam Durbin, Robert Groome, Duncan Harris, Henry Heim, Thomas Keane, Eric Miller, Annie Ping, and Alexandra Wyatt.

The IR range is ideal for the analysis and separation of various silicate types. This work reviews the background knowledge and evaluates the possibilities for mineral identification using high resolution laboratory data. Examples are presented using laboratory based meteorite powder data to evaluate the possibility for identification of plagioclase, estimation on the Mg/(Mg þ Fe) ratio and other characteristics. The expected peak position shift from temperature differences on a rotating asteroid might be below 0.01 μm, while the fine structure of bands requires high spectral À resolution as well. However, with moderate resolution, the analysis of three main minerals is still possible, focusing at the range of 12.5–9.09 μm (800-1100 cm 1) À with spectral resolution of about 0.08 μm (10 cm 1), to identify the expected main bands of olivine, pyroxene and feldspars.

    GUIDANCE, NAVIGATION, AND CONTROL 2019 AAS PRESIDENT Carol S. Lane Cynergy LLC VICE PRESIDENT – PUBLICATIONS James V. McAdams KinetX Inc. EDITOR Heidi E. Hallowell Ball Aerospace SERIES EDITOR Robert H. Jacobs Univelt, Incorporated Front Cover Illustration: “NASA’s Kepler space telescope may be retired, but the discoveries continue to rack up for this historic planet-hunting mission. Kepler rang in the new year with several new planet discoveries, including a previously overlooked planet of an unusual size, as well as a super Earth and a Saturn-sized world orbiting a Sun-like star. In the meantime, the Kepler mission has released its final record of the spacecraft’s full field of view before the depletion of fuel permanently ended its work. NASA retired the spacecraft on Oct. 30, 2018, to a safe orbit. The “last light” image taken on Sept. 25 represents the final page of the final chapter of Kepler’s remarkable journey of data collection. It bookends the moment of intense excitement nine and a half years earlier when the spacecraft first opened its eye to the skies and captured its “first light” image. Kepler went on to discover more than 2,600 worlds beyond our solar system and statistically proved that our galaxy has even more planets than stars. The blackened gaps in the center and along the top of the image are the result of earlier random part failures in the camera. Due to the modular design, the losses did not impact the rest of the instrument. For this final field of view, Kepler’s last observation campaign in its extended mission, the telescope was pointed in the direction of the constellation Aquarius.

However, constraints on the mission (both planned and unplanned), the only partially successful Philae lander, and other instrumental issues have inevitably resulted in open questions. Surprising results from the many successful Rosetta observations have also opened new questions, unimagined when Rosetta was first planned. We discuss these and introduce several mission concepts that might address these issues.
