Misc: Rockets and Relativity + Orbitmuse’s space entrepreneurial network and technology platform + New Worlds 2018

Some items of interest found recently in my email box:

** Rockets and Relativity | Adventures in Physics and the Cosmos by Jeff Palmer

Over the past few years, with the aim of sharing my lifelong enthusiasm for Space Science with other people young and old, I have developed a series of Excel spreadsheets that explore many of the core ideas in Astronautics. Using Newton’s laws of motion and gravity and employing only basic mathematics they demonstrate that the flight of a Rocket attempting to achieve orbit around a chosen planet at a target height can be realistically modelled in a spreadsheet.

The Rocket’s ascent trajectory and any resulting circular or elliptical orbit are calculated based on the spreadsheet user’s input parameters for the space mission. The parameters determine the configuration of a two stage Rocket, specify the characteristics of a planet, and define the guidance instructions that the Rocket must follow.

I have also developed a spreadsheet that explores the concepts in Einstein’s Special Theory of Relativity in some depth. The main concepts in the theory are illustrated using a series of worked examples, where again only basic mathematics is involved.

If this is of any interest to you, please visit my website www.rocketsandrelativity.co.uk to see details about my two books which feature the spreadsheets and explain their design. The spreadsheets are available for free download from the site to enable readers to “fly” their own orbital missions, and to experiment with the ideas in Special Relativity.

I am in the process of developing a rather more ambitious spreadsheet that models the soft landing of a Spacecraft from orbit around an airless planet using only Rocket thrust. This is the subject of my third book which I plan to publish in 2019.

In addition, I have developed a range of supporting PowerPoint slides and animations for use in presentations and demonstrations.

“ROCKETS ORBITS AND NEWTON” – Astronautics topics covered in the book:

  • Newton’s laws of motion and gravity
  • Mass, weight, inertia and weightlessness

  • Circular motion and the conditions required for a circular orbit
  • Guiding Rockets by vectoring their thrust
  • Comparing the performance of a single and a two stage Rocket
  • Modelling a two stage Rocket’s flight to orbit
  • Modelling elliptical orbits

 “LIGHT NEEDS TIME” – Special Relativity topics covered in the book:

  • Spacetime diagrams
  • Moving clocks and rulers
  • Loss of simultaneity
  • Summing relative speeds
  • Momentum and Energy
  • High speed space missions

** Community Development PartnershipOrbitmuse Inc. and NewSpace Chicago

Orbitmuse Inc. and NewSpace Chicago are pleased to announce a ground breaking Community Development Partnership to bring the Space and Aerospace entrepreneurial communities in the Midwest to the forefront of the New Space Race. The partnership aims to promote Orbitmuse’s Habitat strategic partnership location within mHUB Chicago and inspire growth in start-up interest in the Chicagoland business community.

Orbitmuse Inc. is the global Space and Aerospace entrepreneurial network and technology platform providing the essential tools and education to fund, build, and launch your Space, Aerospace, UAV, or Defense venture. Orbitmuse’s product offerings include Habitat, co-working and innovation facilities with dynamic state-of-the-art prototyping labs and startup resources; Boost, a specialized crowdfunding platform designed to promote and fund your projects; and Masters, the one-of-a-kind learning platform to bring your business and technologies to life.

NewSpace Chicago (“NSC”) is the premier Midwest community of professionals and investors driving commercialization and development of Space. NSC is promoting Chicago as a Center of Excellence for new commercial Space, Space-related, and Space-scalable ventures. NSC sponsors monthly network events and other programs supporting Space entrepreneurship in Chicago. With deep roots in the startup and technology communities, NSC provides a strong local presence for Orbitmuse to accelerate its growth in the Midwest. Building on the organic momentum of NSC’s community of nearly 400 members, this partnership provides exciting new opportunities for mentorship, investment, and active participation in Orbitmuse’s ecosystem by the Chicago community.

Together, the partnership aligns our core missions and will help our communities succeed with greater insight and resources. Members at Orbitmuse’s Habitat location within mHUB will have access to Orbitmuse’s global space entrepreneurship network and mHUB’s unparalleled coworking and innovation facility, with state-of-the-art prototyping equipment and resources, including a fully equipped 3D Printer Lab, Cold Metals Lab, Electronics Lab, Hot Metals Lab, Laser Cutting Lab, and Plastics Lab.
