Spitzer, with a sensitivity that is almost three orders of magnitude greater than that of any previous ground-based and space-based infrared observatory, is expected to revolutionize our understanding of the creation of the universe, the formation and evolution of primitive galaxies, the origin of stars and planets, and the chemical evolution of the universe. -
Tiny "Chipsat" Spacecra Set for First Flight
7/24/2019 Tiny "Chipsat" Spacecraft Set for First Flight - Scientific American Subscribe S P A C E Tiny "Chipsat" Spacecra Set for First Flight Launch in July will test new way to explore the solar system—and beyond By Nicola Jones, Nature magazine on June 1, 2016 A rearward view of the International Space Station. Credit: NASA/Crew of STS-132 On 6 July, if all goes to plan, a pack of about 100 sticky-note-sized ‘chipsats’ will be launched up to the International Space Station for a landmark deployment. During a brief few days of testing, the minuscule satellites will transmit data on their energy load and orientation before they drift out of orbit and burn up in Earth’s atmosphere. https://www.scientificamerican.com/article/tiny-chipsat-spacecraft-set-for-first-flight/ 1/6 7/24/2019 Tiny "Chipsat" Spacecraft Set for First Flight - Scientific American The chipsats, flat squares that measure just 3.2 centimetres to a side and weigh about 5 grams apiece, were designed for a PhD project. Yet their upcoming test in space is a baby step for the much-publicized Breakthrough Starshot mission, an effort led by billionaire Yuri Milner to send tiny probes on an interstellar voyage. “We’re extremely excited,” says Brett Streetman, an aerospace engineer at the non- profit Charles Stark Draper Laboratory in Cambridge, Massachusetts, who has investigated the feasibility of sending chipsats to Jupiter’s moon Europa. “This will give flight heritage to the chipsat platform and prove to people that they’re a real thing with real potential.” The probes are the most diminutive members of a growing family of small satellites. -
Two Fundamental Theorems About the Definite Integral
Two Fundamental Theorems about the Definite Integral These lecture notes develop the theorem Stewart calls The Fundamental Theorem of Calculus in section 5.3. The approach I use is slightly different than that used by Stewart, but is based on the same fundamental ideas. 1 The definite integral Recall that the expression b f(x) dx ∫a is called the definite integral of f(x) over the interval [a,b] and stands for the area underneath the curve y = f(x) over the interval [a,b] (with the understanding that areas above the x-axis are considered positive and the areas beneath the axis are considered negative). In today's lecture I am going to prove an important connection between the definite integral and the derivative and use that connection to compute the definite integral. The result that I am eventually going to prove sits at the end of a chain of earlier definitions and intermediate results. 2 Some important facts about continuous functions The first intermediate result we are going to have to prove along the way depends on some definitions and theorems concerning continuous functions. Here are those definitions and theorems. The definition of continuity A function f(x) is continuous at a point x = a if the following hold 1. f(a) exists 2. lim f(x) exists xœa 3. lim f(x) = f(a) xœa 1 A function f(x) is continuous in an interval [a,b] if it is continuous at every point in that interval. The extreme value theorem Let f(x) be a continuous function in an interval [a,b]. -

Continuity. Derivative: definition, rules, geometric and rate-of- change interpretations, applications to graphing, linearization and optimization. Integral: definition, fundamental theorem of calculus, substitution, applications to areas, volumes, work, average. Meets New Mexico Lower Division General Education Common Core Curriculum Area II: Mathematics (NMCCN 1614). (4 Credit Hours). Prerequisites: ((123 or ACCUPLACER College-Level Math =100-120) and (150 or ACT Math =28- 31 or SAT Math Section =660-729)) or (153 or ACT Math =>32 or SAT Math Section =>730). COURSE OBJECTIVES: 1. State, motivate and interpret the definitions of continuity, the derivative, and the definite integral of a function, including an illustrative figure, and apply the definition to test for continuity and differentiability. In all cases, limits are computed using correct and clear notation. Student is able to interpret the derivative as an instantaneous rate of change, and the definite integral as an averaging process. 2. Use the derivative to graph functions, approximate functions, and solve optimization problems. In all cases, the work, including all necessary algebra, is shown clearly, concisely, in a well-organized fashion. Graphs are neat and well-annotated, clearly indicating limiting behavior. English sentences summarize the main results and appropriate units are used for all dimensional applications. 3. Graph, differentiate, optimize, approximate and integrate functions containing parameters, and functions defined piecewise. Differentiate and approximate functions defined implicitly. 4. Apply tools from pre-calculus and trigonometry correctly in multi-step problems, such as basic geometric formulas, graphs of basic functions, and algebra to solve equations and inequalities. -

Differentiating an Integral
Differentiating an Integral P. Haile, February 2020 b(t) Leibniz Rule. If (t) = a(t) f(z, t)dz, then R d b(t) @f(z, t) db da = dz + f (b(t), t) f (a(t), t) . dt @t dt dt Za(t) That’s the rule; now let’s see why this is so. We start by reviewing some things you already know. Let f be a smooth univariate function (i.e., a “nice” function of one variable). We know from the fundamental theorem of calculus that if the function is defined as x (x) = f(z) dz Zc (where c is a constant) then d (x) = f(x). (1) dx You can gain some really useful intuition for this by remembering that the x integral c f(z) dz is the area under the curve y = f(z), between z = a and z = x. Draw this picture to see that as x increases infinitessimally, the added contributionR to the area is f (x). Likewise, if c (x) = f(z) dz Zx then d (x) = f(x). (2) dx Here, an infinitessimal increase in x reduces the area under the curve by an amount equal to the height of the curve. Now suppose f is a function of two variables and define b (t) = f(z, t)dz (3) Za where a and b are constants. Then d (t) b @f(z, t) = dz (4) dt @t Za i.e., we can swap the order of the operations of integration and differentiation and “differentiate under the integral.” You’ve probably done this “swapping” 1 before. -

On the Verge of an Astronomy Cubesat Revolution
On the Verge of an Astronomy CubeSat Revolution Evgenya L. Shkolnik Abstract CubeSats are small satellites built in standard sizes and form fac- tors, which have been growing in popularity but have thus far been largely ignored within the field of astronomy. When deployed as space-based tele- scopes, they enable science experiments not possible with existing or planned large space missions, filling several key gaps in astronomical research. Unlike expensive and highly sought-after space telescopes like the Hubble Space Telescope (HST), whose time must be shared among many instruments and science programs, CubeSats can monitor sources for weeks or months at time, and at wavelengths not accessible from the ground such as the ultraviolet (UV), far-infrared (far-IR) and low-frequency radio. Science cases for Cube- Sats being developed now include a wide variety of astrophysical experiments, including exoplanets, stars, black holes and radio transients. Achieving high- impact astronomical research with CubeSats is becoming increasingly feasible with advances in technologies such as precision pointing, compact sensitive detectors, and the miniaturisation of propulsion systems if needed. CubeSats may also pair with the large space- and ground-based telescopes to provide complementary data to better explain the physical processes observed. A Disruptive & Complementary Innovation Fifty years ago, in December 1968, National Aeronautics and Space Admin- istration (NASA) put in orbit the first satellite for space observations, the Orbiting Astronomical Observatory 2. Since then, astronomical observation from space has always been the domain of big players. Space telescopes are arXiv:1809.00667v1 [astro-ph.IM] 3 Sep 2018 usually designed, built, launched and managed by government space agencies such as NASA, the European Space Agency (ESA) and the Japan Aerospace School of Earth and Space Exploration; Interplanetary Initiative { Arizona State Univer- sity, Tempe, AZ 85287. -
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.
