Tiny ASTERIA Satellite Achieves a First for Cubesats 16 August 2018, by Lauren Hinkel and Mary Knapp
Tiny ASTERIA satellite achieves a first for CubeSats 16 August 2018, by Lauren Hinkel And Mary Knapp The ASTERIA project is a collaboration between MIT and NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, funded through JPL's Phaeton Program. The project started in 2010 as an undergraduate class project in 16.83/12.43 (Space Systems Engineering), involving a technology demonstration of astrophysical measurements using a Cubesat, with a primary goal of training early-career engineers. The ASTERIA mission—of which Department of Earth, Atmospheric and Planetary Sciences Class of 1941 Professor of Planetary Sciences Sara Seager is the Principal Investigator—was designed to demonstrate key technologies, including very Members of the ASTERIA team prepare the petite stable pointing and thermal control for making satellite for its journey to space. Credit: NASA/JPL- extremely precise measurements of stellar Caltech brightness in a tiny satellite. Earlier this year, ASTERIA achieved pointing stability of 0.5 arcseconds and thermal stability of 0.01 degrees Celsius. These technologies are important for A miniature satellite called ASTERIA (Arcsecond precision photometry, i.e., the measurement of Space Telescope Enabling Research in stellar brightness over time. Astrophysics) has measured the transit of a previously-discovered super-Earth exoplanet, 55 Cancri e. This finding shows that miniature satellites, like ASTERIA, are capable of making of sensitive detections of exoplanets via the transit method. While observing 55 Cancri e, which is known to transit, ASTERIA measured a miniscule change in brightness, about 0.04 percent, when the super- Earth crossed in front of its star. This transit measurement is the first of its kind for CubeSats (the class of satellites to which ASTERIA belongs) which are about the size of a briefcase and hitch a ride to space as secondary payloads on rockets used for larger spacecraft. -
Archons (Commanders) [NOTICE: They Are NOT Anlien Parasites], and Then, in a Mirror Image of the Great Emanations of the Pleroma, Hundreds of Lesser Angels
A R C H O N S HIDDEN RULERS THROUGH THE AGES A R C H O N S HIDDEN RULERS THROUGH THE AGES WATCH THIS IMPORTANT VIDEO UFOs, Aliens, and the Question of Contact MUST-SEE THE OCCULT REASON FOR PSYCHOPATHY Organic Portals: Aliens and Psychopaths KNOWLEDGE THROUGH GNOSIS Boris Mouravieff - GNOSIS IN THE BEGINNING ...1 The Gnostic core belief was a strong dualism: that the world of matter was deadening and inferior to a remote nonphysical home, to which an interior divine spark in most humans aspired to return after death. 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. -

ASTERIA Data Guide
ASTERIA Data Users Guide (v2) Mary Knapp November 2019 1 Overview This document describes the formatting and idiosyncrasies of ASTERIA photometric data. ASTERIA is the Arcsecond Space Telescope Enabling Research In Astrophysics. 2 Brief ASTERIA System Description ASTERIA is a 6U (10 cm x 20 cm x 34 cm) CubeSat spacecraft. ASTERIA was launched August 2017 as payload to the International Space Station and deployed into orbit on November 20, 2017. ASTERIA's current orbit matches the ISS inclination and has an average altitude of approximately 400 km. In this orbit, ASTERIA experiences an average of 30 minutes in Earth's shadow (eclipse) and 60 minutes in sunlight. ASTERIA is 3-axis stabilized via a set of reaction wheels. The reaction wheels are part of the XACT attitude control system provided by Blue Canyon Technology (BCT). Torque rods are used for reaction wheel desaturation. ASTERIA carries a small refractive telescope (f/1.4, ∼85 mm). The telescope focuses light on a 2592 x 2192 pixel CMOS detector. The detector pixels are 6.5 microns, yielding a plate scale of ∼15 arcsec/pixel. The full field of view of the detector is ∼9 x 10 degrees. ASTERIA's camera is deliberately defocused in order to oversample the PSF. 3 Definitions List of definitions for acronyms and other terms with specific meanings in the context of ASTERIA. • Epoch: The spacecraft epoch refers to the bootcount of the spacecraft. An epoch begins when ASTE- RIA's flight computer reboots and sets time to January 1, 1970 (the zero point for Unix timestamps). • Uptime: Spacecraft time is relative and is tracked in seconds from flight computer boot. -

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 concept is responsive to recommendations of the recent NASA Roadmap to Ocean Worlds study (Hendrix et al., 2019), and to the 2013 Planetary Decadal Survey’s habitability and workings themes (Squyres et al., 2011). The concept was chosen (Ref. 5) from proposals submitted in 2019, under NASA’s Discovery Program, and is currently in its Phase A, competing for selection with three other mission concepts. Voyager 2 showed that Triton has active resurfacing with the potential for erupting plumes and an atmosphere. Coupled with an ionosphere that can create organic snow and the potential for a subsurface ocean, Triton is an exciting exploration target to understand how habitable worlds may develop in our Solar System and beyond.
