AstronomyCast: 354: Comet Siding Spring vs. Mars by Fraser Cain & Dr. Pamela Gay
Download Episode! The Discussion: Enjoying light pollution-free skies in the Ionian Sea and soaking up the atmosphere at the North West Astronomy Festival. The News: In the news we have more findings about the interior and evolution of our moon from the GRAIL and Lunar Reconnaissance Orbiter missions; Russian and Chinese lunar ambitions ratchet up a notch; the ExoMars mission narrows down its possible 2018 landing sites; sampling the atmospheres of Neptune-sized exoplanets; Comet Siding Spring brushes past Mars; Lockheed Martin claim to have made a breakthrough in fusion reactors; more doubt on the gravitational waves detection by the BICEP2 team and dark matter particles streaming from the sun. The 5 Minute Concept: In a solar maximum year when we have tons of solar activity that we can enjoy in the form of visible details on the sun and auroral activity that’s even reached as far south as central latitudes recently, this month Paul explains sunspots. The Interview: Live interviews recorded from the North West Astronomy Festival from Jodrell Bank’s Professor Philippa Browning, Astrophotographer of the Year 2011’s Damian Peach, BBC Sky at Night presenter Professor Chris Lintott, writer and comedian Helen Keen and the host of the NWAF Andrew Davies. Q&A: Listeners’ questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month Ralph & Paul answer: I know the moon doesn’t spin and that we cannot see the rear of it from Earth, but I wondered if we can ever see a little more of the right or left side (like at different times of the day or year or location on earth)? Ollie Broad from Thailand via Twitter. In your opinions should we send manned mission back to the moon or should we head straight to Mars? Lee Garner from the UK via Twitter .
The Talking Space team plays "catch-up" this week opening the discussion with NASA's Commercial Crew Program (CCP) decision. NASA decided on 16 September, 2014, to go with the conical shaped spacecraft offered by Boeing (CST-100) and SpaceX (Dragon Version 2) over the Sierra Nevada Corporation lifting body design, Dreamchaser. This week, a judge with the US Claims Court allowed NASA to continue work on CCP related activities while the US General Accounting Office considers SNC's challenge to the overall decision. The International Space Station is becoming a very busy place with robotic cargo vehicles coming and going. The team gives a traffic report for the orbiting laboratory with cargo ships from SpaceX, Roscosmos and Orbital Sciences. Want to go to Mars? You can, well okay, virtually. The team describes how to pick up your boarding pass not only for NASA's upcoming Exploration Test Flight 1, but for a future mission to the Red Planet. Our Mars focus continues with the once every million year encounter that occurred on 19 October, 2014 when Comet Siding Spring made its historic close encounter with the fourth rock from the Sun.
