CENTRIPETAL FORCE from GRAVITY Unit 14 & 8
CENTRIPETAL FORCE FROM GRAVITY Unit 14 & 8 Dr. John P. Cise, Professor of Physics, Austin Com. College, Austin , Tx. [email protected] & New York Times November 7, 2017 by Richard Goldstein. Dedicated to all the American Apollo Astronauts in 1960s & 1970s. -------------------------------------------------------------------------------------------------------------------------------------------------------------- Richard Gordon, Astronaut Who Reached for Moon (1969)and Very Nearly Made It, Dies at 88 INTRODUCTION: Gordon commanded the command module Yankee Clipper from 60 miles above moon surface in 1969. The other 2 Apollo Astronauts went to Lunar surface in lunar lander. The radius of moon is 1079 miles. Gordon did 45 orbits of moon over 89 hrs. (3.7 days). Gravity provides centripetal force.

Richard Gordon, who undertook what became a harrowing and abortive spacewalk in a 1966 NASA mission, then orbited the moon three years later, but never achieved his dream of walking on the lunar surface, died on Monday at his home in San Marcos, Calif., near San Diego. He was 88. His death was confirmed by NASA. Mr. Gordon piloted the command module ((Yankee Clipper ))during its orbit of the moon in November 1969 while Mr. -
USGS Open-File Report 2005-1190, Table 1
TABLE 1 GEOLOGIC FIELD-TRAINING OF NASA ASTRONAUTS BETWEEN JANUARY 1963 AND NOVEMBER 1972 The following is a year-by-year listing of the astronaut geologic field training trips planned and led by personnel from the U.S. Geological Survey’s Branches of Astrogeology and Surface Planetary Exploration, in collaboration with the Geology Group at the Manned Spacecraft Center, Houston, Texas at the request of NASA between January 1963 and November 1972. Regional geologic experts from the U.S. Geological Survey and other governmental organizations and universities s also played vital roles in these exercises. [The early training (between 1963 and 1967) involved a rather large contingent of astronauts from NASA groups 1, 2, and 3. For another listing of the astronaut geologic training trips and exercises, including all attending and the general purposed of the exercise, the reader is referred to the following website containing a contribution by William Phinney (Phinney, book submitted to NASA/JSC; also http://www.hq.nasa.gov/office/pao/History/alsj/ap-geotrips.pdf).] 1963 16-18 January 1963: Meteor Crater and San Francisco Volcanic Field near Flagstaff, Arizona (9 astronauts). Among the nine astronaut trainees in Flagstaff for that initial astronaut geologic training exercise was Neil Armstrong--who would become the first man to step foot on the Moon during the historic Apollo 11 mission in July 1969! The other astronauts present included Frank Borman (Apollo 8), Charles "Pete" Conrad (Apollo 12), James Lovell (Apollo 8 and the near-tragic Apollo 13), James McDivitt, Elliot See (killed later in a plane crash), Thomas Stafford (Apollo 10), Edward White (later killed in the tragic Apollo 1 fire at Cape Canaveral), and John Young (Apollo 16). -
Report of Contributions
Open Source CubeSat Workshop 2019 Report of Contributions https://new.satnogs.org/e/3 Open Source Cub … / Report of Contributions An Open Source Implementation o … Contribution ID: 1 Type: Talk An Open Source Implementation of the CCSDS SLE Services in Python Monday, 14 October 2019 09:30 (20 minutes) An Open Source Implementation of the CCSDS SLE Services in Python Milenko Starcik (1), Fabian Burger (1), Artur Scholz (1, 2), Tiago Nogueira (1) (1) VisionSpace Technologies GmbH (2) LibreCube Initiative The Open Source CubeSat community is currently lacking the capability to use existing radio amateur ground-station networks to transfer live data to the end users / mission control centres. SatNOGS, the biggest network of the kind, provides services for archiving and offline distribution of telemetry data. At the moment, an operator using the SatNOGS network is not able to receive telemetry in real-time and make use of the station uplink chain, when available, for direct com- manding. We believe that the community could benefit considerably from services that provide real-time monitoring and control over a distributed ground-station network. As a first step to address the current limitations we introduce in this contribution a newfreeand open source implementation of the CCSDS Space Link Extension (SLE) services in Python. The SLE standard, used by all major space agencies, is one of the most adopted CCSDS standards and is key to enable the inter-agency utilisation of ground-station networks like the Deep Space Network. Additionally, it is supported by most, if not all, private ground-station operators. SLE services have proven reliable, and can be used even for missions, like most CubeSats, that do not adhere to the CCSDS telemetry and telecommand frame and packet formats. -

The Aerospace Update
The Aerospace Update Dec. 28, 2017 Top 2017 Space Images Video Credit: NASA SpaceX Concludes 2017 With Fourth Iridium Next launch SpaceX closed out its most successful year to date Dec. 22nd with the launch of 10 satellites for mobile satellite services operator Iridium, notching a personal best of 18 launches in a single year. The Falcon 9 mission, which took off from Vandenberg Air Force Base in California at 8:27 p.m. Eastern in an instantaneous launch window, was the fourth of eight missions for Iridium, carrying the McLean, Virginia- based operator’s second generation satellites, called Iridium Next. In what now is considered a rarity, SpaceX opted not to recover the rocket’s first stage, instead letting the booster fall into the Pacific Ocean. Video Credit: SpaceX Source: Caleb Henry @ SpaceNews.com Zenit Rocket Launches AngoSat-1 but Ground Control Loses Contact A Russian-Ukrainian Zenit rocket was launched on Tuesday, December 26th, with the aim of delivering into orbit Angola’s first satellite, known as AngoSat-1. However, it appears that contact with the spacecraft was lost after its deployment into orbit. The booster lifted off from Site 45/1 at the Baikonur Cosmodrome in Kazakhstan. Tuesday’s launch marked the first Zenit flight in more than two years when it orbited the Elektro-L № 2 weather satellite for Roscosmos. The rocket returned to flight despite fears that the Russian-Ukrainian conflict, which started in 2014, would kill any joint efforts between these two countries.

Ebinuma Surrey Space Centre, University of Surrey Guildford, Surrey GU2 7XH, UK Tel: +44 (0)1483 683882, [email protected] Abstract. Enabling technologies for nanosatellite formations will be demonstrated under the Formation Autonomy Spacecraft with Thrust, Relnav, Attitude, and Crosslink (FASTRAC) program. Two flight-ready nanosatellites will be designed, fabricated, integrated, and tested during the two year design period. Three speci¯c new and innovative technologies which will be demonstrated during the mission are Relative Navigation, Plasma Microthrusters, and Distributed Communications. A sensor set consisting of Global Positioning System (GPS) receiver, magnetometer, and MEMS Inertial Measurement Unit (IMU) will be used to determine position and coarse attitude. Using a radio crosslink, the two satellites will exchange state vector information and perform sub-meter level accuracy relative navigation. Each satellite will also contain a Microdischarge Plasma Thruster (MPT) developed at UT-Austin. This innovative device is capable of generating low-thrust, high-e±ciency propulsion at low power levels using microdischarge plasmas. The ability of the MPT to extend the life of the orbit will be determined by monitoring the orbit decay rates of the two vehicles as well as the MEMS IMU. -

By establishing government-industry partnerships, the Commercial Orbital Transportation Services (COTS) program marked a change from the traditional way NASA had worked. Inset photos, right: The COTS program supported two U.S. companies in their efforts to design and build transportation systems to carry cargo to low-Earth orbit. (Top photo—Credit: SpaceX) SpaceX launched its Falcon 9 rocket on May 22, 2012, from Cape Canaveral, Florida. (Second photo) Three days later, the company successfully completed the mission that sent its Dragon spacecraft to the Station. (Third photo—Credit: NASA/Bill Ingalls) Orbital Sciences Corp. sent its Antares rocket on its test flight on April 21, 2013, from a new launchpad on Virginia’s eastern shore. Later that year, the second Antares lifted off with Orbital’s cargo capsule, (Fourth photo) the Cygnus, that berthed with the ISS on September 29, 2013. Both companies successfully proved the capability to deliver cargo to the International Space Station by U.S. commercial companies and began a new era of spaceflight.
