Part I: Introduction
Part I: Introduction “Perhaps the sentiments contained in the following pages are not yet sufficiently fashionable to procure them general favor; a long habit of not thinking a thing wrong gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom. But the tumult soon subsides. Time makes more converts than reason.” -Thomas Paine, Common Sense (1776) “For my part, whatever anguish of spirit it may cost, I am willing to know the whole truth; to know the worst and provide for it.” -Patrick Henry (1776) “I am aware that many object to the severity of my language; but is there not cause for severity? I will be as harsh as truth. On this subject I do not wish to think, or speak, or write, with moderation. No! No! Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it has fallen -- but urge me not to use moderation in a cause like the present. The apathy of the people is enough to make every statue leap from its pedestal, and to hasten the resurrection of the dead.” -William Lloyd Garrison, The Liberator (1831) “Gas is running low . .” -Amelia Earhart (July 2, 1937) 1 2 Dear Reader, Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. -

ALPO COMET NEWS for APRIL 2020 a Publication of the Comet Section of the Association of Lunar and Planetary Observers by Carl Hergenrother - 2020-April-1
ALPO COMET NEWS FOR APRIL 2020 A Publication of the Comet Section of the Association of Lunar and Planetary Observers By Carl Hergenrother - 2020-April-1 The monthly ALPO Comet News PDF can be found on the ALPO Comet Section website (http://www.alpo-astronomy.org/cometblog/). A shorter version of this report is posted on a dedicated Cloudy Nights forum (https://www.cloudynights.com/topic/700215-alpo-comet-news- for-april-2020/). All are encourageD to join the discussion over at Cloudy Nights. The ALPO Comet Section welcomes all comet related observations, whether textual descriptions, images, drawings, magnitude estimates, or spectra. You do not have to be a member of ALPO to submit material, though membership is encouraged. To learn more about the ALPO, please visit us @ http://www.alpo-astronomy.org. A lot has changed since over the past month, not only with the state of the world, but with comets. C/2019 Y4 (ATLAS) has asserted itself as the comet of the moment. Currently between 7th and 8th magnitude as April begins, the comet may become a borderline naked eye object under dark skies by the end of the month. It will be interesting to watch how it develops. C/2019 Y4 isn’t the only object of interest. Both C/2017 T2 (PANSTARRS) and C/2019 Y1 (ATLAS) are brighter than 10th magnitude and CCD and large aperture visual observers are encouraged to watch fainter comets 88P/Howell, 210P/Christensen, 249P/LINEAR, and C/2019 U6 (Lemmon). Bright Comets (magnitude < 10.0) C/2019 Y4 (ATLAS) – The Great Comet of 2020, a Great Disappointment, or something in between? For the first time since 2013, a comet has the potential to become something special. -

Space debris are all man made objects including fragments and elements thereof, in Earth orbit or re-entering the atmosphere, that are non functional. Obtial debris is the only man-made Space environment. The past 50 years of space exploration has unfortunately generated a lot of junk that threatens the reliability of spacecraft. The Space Debris Environment in 2010 More than 5000 satellite launches since 1957 till the end of October 2010; 245 on-orbit break-ups led to 12,500 objects in the US Space Surveillance catalog; catalog size threshold 10cm; mass on orbit 6,000 tons; catalog orbit distributions: - low Earth orbits 73%; - near-geostationary orbits 8%; - highly eccentric orbits 10%; - other orbits (incl. -
Ice & Stone 2020
Ice & Stone 2020 WEEK 17: APRIL 19-25, 2020 Presented by The Earthrise Institute # 17 Authored by Alan Hale This week in history APRIL 19 20 21 22 23 24 25 APRIL 20, 1910: Comet 1P/Halley passes through perihelion at a heliocentric distance of 0.587 AU. Halley’s 1910 return, which is described in a previous “Special Topics” presentation, was quite favorable, with a close approach to Earth (0.15 AU) and the exhibiting of the longest cometary tail ever recorded. APRIL 20, 2025: NASA’s Lucy mission is scheduled to pass by the main belt asteroid (52246) Donaldjohanson. Lucy is discussed in a previous “Special Topics” presentation. APRIL 19 20 21 22 23 24 25 APRIL 21, 2024: Comet 12P/Pons-Brooks is predicted to pass through perihelion at a heliocentric distance of 0.781 AU. This comet, with a discussion of its viewing prospects for 2024, is a previous “Comet of the Week.” APRIL 19 20 21 22 23 24 25 APRIL 22, 2020: The annual Lyrid meteor shower should be at its peak. Normally this shower is fairly weak, with a peak rate of not much more than 10 meteors per hour, but has been known to exhibit significantly stronger activity on occasion. The moon is at its “new” phase on April 23 this year and thus the viewing circumstances are very good. COVER IMAGE CREDIT: Front and back cover: This artist’s conception shows how families of asteroids are created. Over the history of our solar system, catastrophic collisions between asteroids located in the belt between Mars and Jupiter have formed families of objects on similar orbits around the sun. -

JPL Technology Highlights from 2020
Jet Propulsion LaboratoryJet Propulsion National Aeronautics and Space Administration Technology Highlights Technology 2020 TECHnOLOGY HIGHLIGHTS Jet Propulsion Laboratory National Aeronautics and Space Administration Jet Propulsion Laboratory California Institute of Technology Pasadena, California www.jpl.nasa.gov 2020 CL#20-6401 This JPL 2020 Technology Highlights presents a diverse set of technology developments — selected by the Chief Technologist out of many similar efforts at JPL — that are essential for JPL’s continuing contribution to NASA’s future success. These technology snapshots represent the work of individuals whose talents bridge science, technology, engineering, and management, and illustrate the broad spectrum of knowledge and technical skills at JPL. While this document identifies important areas of technology development in 2019, many other technologies remain equally important to JPL’s ability to successfully contribute to NASA’s space exploration missions, including mature technologies that are commercially available and technologies whose leadership is firmly established elsewhere. About the cover: the Mars Helicopter, 1 known as Ingenuity, is set to perform the first powered flight on another world. HIGHLIGHTS TECHNOLOGY 2020 As NASA’s leading center for robotic exploration of the universe, JPL develops technologies that advance our pursuit of discoveries to the benefit of humanity. Although our technologies are to enable science, they often have dual use for commercial and urgent societal needs. Despite the pandemic, JPL accomplished Prioritizing technology development and infusion has OFFICE OF THE its biggest goal of 2020. The next Mars always been a crucial piece of the Laboratory’s mission rover, Perseverance, is healthy and well on its success. No one has tried to dig kilometers through the icy way to the Red Planet.
