Boeing Company engineers are working with extruders on a massive scale during construction and assembly of the newest extruded truss sections: Starboard segments S3, S4, S6, and Portside segments P3, P4 and P5, scheduled to begin launching in Spring, 2005. Truss section P6, launched in November 2000, supports the current ISS configuration. A marvel of science and aerospace engineering, this vast ISS program is truly flourishing thanks to aluminum extruders across the globe.

Educ. 55 (2020) 025011 (9pp) iopscience.org/ped 2020 SpaceX rocket data satisfies © 2020 IOP Publishing Ltd elementary Hohmann transfer PHEDA7 formula 025011 Michael J Ruiz and James Perkins M J Ruiz and J Perkins Department of Physics and Astronomy, University of North Carolina at Asheville, Asheville, NC 28804, United States of America SpaceX rocket data satisfies elementary Hohmann transfer formula E-mail: [email protected] and [email protected] Printed in the UK Abstract The private company SpaceX regularly launches satellites into geostationary PED orbits. SpaceX posts videos of these flights with telemetry data displaying the time from launch, altitude, and rocket speed in real time. In this paper 10.1088/1361-6552/ab5f4c this telemetry information is used to determine the velocity boost of the rocket as it leaves its circular parking orbit around the Earth to enter a Hohmann transfer orbit, an elliptical orbit on which the spacecraft reaches 1361-6552 a high altitude. A simple derivation is given for the Hohmann transfer velocity boost that introductory students can derive on their own with a little teacher guidance. They can then use the SpaceX telemetry data to verify the Published theoretical results, finding the discrepancy between observation and theory to be 3% or less. The students will love the rocket videos as the launches and 3 transfer burns are very exciting to watch. 2 Introduction Complex 39A at the NASA Kennedy Space Center in Cape Canaveral, Florida.

    SPACEX CRS-11 MISSION OVERVIEW SpaceX’s eleventh contracted cargo resupply mission with NASA to the International Space Station will deliver almost 6,000 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew. Launch is targeted for Thursday, June 1, 2017. The Dragon spacecraft will launch aboard a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida and arrive at the space station two days later. Expedition 51 crew members Peggy Whitson and Jack Fischer of NASA, Thomas Pesquet of ESA (European Space Agency) and cosmonauts Oleg Novitskiy and Fyodor Yurchikhin of Roscosmos are currently living aboard the orbiting laboratory. Pesquet and Novitskiy are slated to return to Earth June 2 which will mark the start of Expedition 52. Fischer and Whitson will use the station’s robotic arm to capture Dragon when it arrives on station. The spacecraft will be berthed to the Earth-facing port on the Harmony module. Dragon will carry hardware and supplies to support dozens of the of approximately 250 science and research investigations that will occur during Expeditions 52 and 53. The unpressurized trunk of the spacecraft will also hold three payloads that will study neutron stars, test solar arrays, and hold instruments for Earth-observation.
