Hubble Space Telescope Starts 26th Year of Cutting Edge Exploration

Currently generating about 844 gigabytes of data per month, totaling more than 100 terabytes of information used in over 11,000 scientific papers to date, Hubble is one of the most productive scientific instruments ever built. Funding of the joint NASA-ESA project is expected to continue at least until the succeeding James Webb Space Telescope becomes operational NET 2018. Regardless of instrument health and funding, final orbital decay is expected 2030-2040, depending on solar activity and resulting fluctuations of atmospheric drag. The observatory maintains a circular orbit of about 560km altitude and has pointing accuracy sufficient to hold a target to less than 7/1,000th of an arc second deviation while the spacecraft is moving at 7,160 meters per second. Over 38,000 celestial objects have been imaged, revealing new aspects of subjects as profound as the age of the Universe and as mysterious as dark energy and black holes. Events commemorating the 25th Anniversary of Hubble, deployed by STS-31 Discovery and astronomer astronaut Steven Hawley of the Ad Astra State of Kansas on April 25, 1990, bring into focus the transformative power of astronomy to enhance human understanding and imagination. NASA Administrator Charlie Bolden and Associate Administrator for Science John Grunsfeld, and Hubble Senior Project Scientist Jennifer Wiseman will preside over the presentation of the Hubble 25th Anniversary image on April 23 in Washington DC. One of many events celebrating the mission, which will also be featured at the Smithsonian’s National Air and Space Museum throughout April.(Image Credit: ESA/Hubble; NASA, ESA, Hubble Heritage Team, STSciI, AURA)

Space Access Society Supporting Private / Public Low-Cost Space Ventures

The Space Access Society will be hosting its Space Access 2015 Conference in Phoenix, Arizona on April 30 – May 2 at the Radisson Hotel Phoenix North. The conference will feature more than 21 hours on current and future technologies, businesses and politics of cheaper space transportation. There will be a special session on ‘Return to the Moon’ by Doug Plata who is proposing to use the successful Commercial Cargo transportation model to facilitate lunar commercial development, transportation and habitation. This session will also feature talks by Jeff Greason (market implication of lunar return), Pascal Lee (the Moon and the road to Mars), Dave Masten (on low-cost access to lunar surface) and Erik Seedhouse (lunar surface crew factors and habitats). Also presenting during the conference will be Jon Goff (Altius Space Machines), Jeff Foust (The Space Review), Clark Lindsey (NewSpace Global), Doug Messier (Parabolic Arc), Ben Brockert (Moon Express), Gary Hudson (Space Studies Institute), Peter Swan (International Space Elevator Consortium) and Ed Wright (Citizens in Space). Henry Vanderbilt (Top), Executive Director and Founder of SAS 1992, continues to organize the annual conference and contribute to the long-standing Space Access Updates.
