“Gateway Earth” – Low Cost Access to Interplanetary Space
RIS-2015-13 “Gateway Earth” – Low Cost Access to Interplanetary Space Derek Webber, FBIS, Senior Member AIAA Spaceport Associates PO Box 614, Damariscotta, Maine 04543, USA 207-563-2660 [email protected], www.SpaceportAssociates.com INTRODUCTION The paper describes some aspects of a proposed space development whose aim is to dramatically reduce the cost of missions, both crewed and robotic, to anywhere in the solar system. The concept uses a funding mechanism combining governmental and commercial financing working in new ways together. The aim is to enable interplanetary space transportation and exploration within realistic funding projections. The basic architecture uses a combined governmental/commercial space station (“Gateway Earth”) located in geostationary orbit (near the edge of Earth’s gravity well) and a logistical supply chain of reusable tugs going regularly between LEO (Low Earth Orbit) and GEO (Geostationary Orbit) and back. Part of the commercial station would be a GEO space tourist hotel. Other commercial uses of the Gateway complex would include servicing of GEO communications satellites. “Gateway Earth”, the station at the edge of interplanetary space, would consequently be partly funded by space tourism revenues, as would also be the operation of the tugs. It’s a way of exploring the solar system by using space tourism revenues to augment government funding. The paper addresses some design implications of including an industrial scale 3-D manufacturing facility at the Gateway complex, for building and assembling components of craft intended for ongoing interplanetary travel. Elements of a business case framework are presented, using market analogs for this next destination of space tourists beyond LEO, which supports the argument that the “Gateway Earth” architecture represents a way to achieve relatively low cost interplanetary travel. -

Phobos, Deimos: Formation and Evolution Alex Soumbatov-Gur The moons are confirmed to be ejected parts of Mars’ crust. After explosive throwing out as cone-like rocks they plastically evolved with density decays and materials transformations. Their expansion evolutions were accompanied by global ruptures and small scale rock ejections with concurrent crater formations. The scenario reconciles orbital and physical parameters of the moons. It coherently explains dozens of their properties including spectra, appearances, size differences, crater locations, fracture symmetries, orbits, evolution trends, geologic activity, Phobos’ grooves, mechanism of their origin, etc. The ejective approach is also discussed in the context of observational data on near-Earth asteroids, main belt asteroids Steins, Vesta, and Mars. The approach incorporates known fission mechanism of formation of miniature asteroids, logically accounts for its outliers, and naturally explains formations of small celestial bodies of various sizes. -
Why Do We Explore?
Why Do We Explore? Lesson Six Why Do We Explore? About This Lesson Students will work in small teams, each of which will be given a different reason why humans explore. Each team will become the expert on their one reason and will add a letter and summary sentence to an EXPLORE poster using their reason for exploration. With all the reasons on the poster, the word EXPLORE will be complete. Students will be using the skills of working in cooperative learning teams, reading, summarizing, paraphrasing, and creating a sentence that will best represent their reason for exploration. Students will also be illustrating and copying other teams sentences so that each student will have a small copy of the large class- room poster for reference or extension purposes. The teacher will lead a discussion that relates the reasons humans explore to the planned and possible future missions to Mars. Objectives Students will: v review the seven traditional reasons why people explore v write a summary of their reason why humans explore v illustrate their exploration summaries v relate the reasons for exploration to the missions to Mars Background Students do not always realize that the steps in future exploration are built on a tradition of Why Do We Explore? exploration that is as old as humans. This lesson is intended to introduce the concept of exploration through the seven traditional reasons that express why humans have always been explorers. Social scientists know that everyone, no matter how young or old, is constantly exploring the world and how it works. Space exploration, including the possible missions to Mars, has opened up a whole new world for us to explore. -

The “Farm:” an Inflatable Centrifuge Biology Research Module on the International Space Station
The “Farm:” An Inflatable Centrifuge Biology Research Module on the International Space Station M.Thangavelu1, L. Simurda2 As the sole manned laboratory in Low Earth Orbit, permanently operating in microgravity and largely unprotected by the Earth's atmosphere, the International Space Station serves as an unparalleled platform for studying the effects of low or zero-gravity and the space radiation environment on biological systems as well as developing, testing and certifying sturdy and reliable systems for long duration missions such as ambitious interplanetary expeditions planned for the future. Earth- bound research, automated research aboard satellites and short missions into low- altitude orbits cannot replicate long-term ISS experiments. Abandoning or de- orbiting the station, even in 2020, leaves the international scientific and engineering community bereft of a manned station in orbit and destroys any opportunity for conducting long-term microgravity and radiation experiments requiring human oversight in space. The United States should invest in extending the station's life by a minimum of 15 years from present by attaching an inflatable "Farm" centrifuge module to equip biologists, psychologists and engineers with the tools required to investigate these questions and more. At a time when humankind has only begun exploring the effects of the space environment on biological systems, it is essential that we not abandon the only empirical research facility in operation today and instead begin vigorously pursuing research in this area that is of vital importance to all humanity, not only in the basic and applied sciences but also in international collaboration. I. Introduction In June 2010, President Barack Obama announced a novel vision for NASA and proposed extending the life of the International Space Station (ISS) until at least 2020. -

The descent probe is a carry-on small spacecraft (< 100 kg), to be deployed by the mother spacecraft, that brings itself onto a collisional trajectory with the targeted planetary body in a simple manner. A possible science payload includes instruments for surface imaging, characterisation of the neutral exosphere, and magnetic field and plasma measurement near the target body down to very low-altitudes (~1 km), during the probe’s fast (~km/s) descent to the surface until impact. The science goals and the concept of operation are discussed with particular reference to Europa, including options for flying through water plumes and after-impact retrieval of very-low altitude science data. -

Nield, Associate Administrator for Commercial Space Transportation at the Federal Aviation Administration (FAA), addressed the future of commercial space travel: “There is tangible work underway by a number of companies aiming for space, partly because of their dreams, but primarily because they are confident it can be done by the private sector and it can be done at a profit.” Indeed, private companies and entrepreneurs are currently aiming to make this dream a reality. While the current economic downturn will likely slow industry progress, space tourism, currently in its infancy, is poised to become a significant part of the hospitality industry. Unlike the space race of the 1950s and 1960s between the United States and the former Soviet Union, the current rivalry is not defined on a national level, but by a collection of first-mover entrepreneurs that are working to define the industry and position it for long- term profitability. -
