Today In Space

EXPLICIT MATERIAL POSSIBLE In Part 1 of this Two Part episode, Alex has Brian Folan (artist/musician out of Providence, RI) on the show to discuss Dark Energy. This episode is part of the "Opinion Panel" where Alex brings people who are interested in space and science to come on and give their opinion. The idea is to get people who aren't involved in science to "ask questions" and talk about Space. This is the first try. Enjoy! From "What is Dark Energy?", to "How do we know there is Dark Energy?", Alex and Brian sit down and talk about this crazy mystery that is supposed to make up 68% of the Universe. Relax, listen and enjoy! If you want to check out Brian Folan's music, go to Brian4ever.bandcamp.com Topics in this Episode: Dark Energy, Dark Matter, the Composition of the Universe, Planck Telescope,  Space Links: http://www.nasa.gov/mission_pages/planck/news/planck20130321.html#.VKGyBkACHQ http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/

EXPLICIT MATERIAL POSSIBLE The Sierra Nevada Corporation Dream Chaser flight vehicle is readied for 60 mph tow tests at NASA's Dryden Flight Research Center on Aug. 2, 2013 Credit: NASA/Ken Ulbrich Alex talks about the postponing of SpaceX's CRS-5 mission to resupply the ISS and also talks about some other private companies and what they are doing to help bring the cost down for space travel and help make it safer. The companies discussed are Sierra Nevada Corporations (SNC) Space Systems and Blue Origins, LLC.

EXPLICIT MATERIAL Alex brings you the information you should know as New Horizons makes its approach to Pluto and it's moons. Alex explains the history of why Pluto became classified as a "dwarf planet" in 2006. Learn a little bit about the mission & what to expect during the time until New Horizons reaches its closest approach to Pluto on July 14, 2015. Also, Alex goes over the different data the science team is planned to gather during their time at Pluto. An artist's drawing shows the New Horizons spacecraft as it nears Pluto.

EXPLICIT Content Possible Alex talks about the technology that will be tested on the next SpaceX launch (CRS-5) on December 16th, 2014: Hypersonic Grid Fins https://twitter.com/elonmusk/status/536258543675252739/photo/1 Autonomous Spaceport Drone Ship https://twitter.com/elonmusk/status/536262624653365248/photo/1 Alex then talks about the craziness that is the space race we are in the middle of, and he talks about how he got into the space industry. SpaceX unveiled its Dragon V2 spacecraft designed to carry humans into orbit. The company's founder and CEO, Elon Musk, detailed aspects of the design that was developed in partnership with NASA's Commercial Crew Program.

Alex gives you a play-by-play of the successful test flight of the Orion service module. Rapidly going through the highlights for today's incredible accomplishment, Alex goes through each major step, explaining different aspects of the mission as well.   Alex also shows you how to 'properly' react to this historic event, not only as an American, but as a human being.

EXPLICIT MATERIAL Today, the Orion Test Flight attempted to launch and faced several challenges during it's launch window and had to scrub the launch for 24 hours.   Alex goes over the first (scrubbed) launch of the Orion Spacecraft from Launch Complex 37 at Cape Canaveral Air Force Station.   He goes over the incidents that caused the delay. ("Higher-than-expected" winds, another boat, and "sticky" Hydrogen Valves) He tells the story of the "Four-Inch Launch" of the Mercury-Redstone 1 (MR-1) ...and gets a little too excitable about the boat that entered "restricted area".   FAN Question: How do I subscribe/set-up/use a podcast app? How does it work? ANSWER: A HOW-TO for setting up a podcast (any podcast on multiple devices) so that you can listen to it in the best way possible will be up tomorrow.
