John Batchelor and I welcomed back Dr. Marc Rayman to the show to discuss the latest news coming back from the Dawn Mission regarding dwarf planet Ceres. We talked about the Ceres topography including the bright spots, the haze in crater Occator, the three mile high pyramid peak which may be remnants of a volcano, plus the dust layer over Ceres, ice, and oceans under the ice. Dr. Ryman talked about some of the processes that might have created these characteristics and conditions on Ceres but as you will hear, much is still unexplained. Dawn will make a close pass of Ceres at 900 miles from the surface in early August. Its closest pass will be in December 2015 at about 232 miles above the surface. Check out the new Dawn color coded topography map at http://dawn.jpl.nasa.gov.

John Batchelor and I welcomed back Dr. Marc Rayman to update us on the latest with the Dawn Mission and Ceres. We talked about the bright spots on Ceres that are still a mystery, dwarf planets, possible similarities with Pluto, what’s ahead for the Dawn Mission and Ceres, plus why it is unlikely that there be ice on the surface of Ceres. We also talked about the end game for Dawn and the fact that dawn was not equipped to detect a magnetic field on Ceres.

We welcomed back Brent Sherwood for updates to his human spaceflight analysis work previously presented on The Space Show.  During the first segment of our 1 hour 48 minute discussion, Brent started out with a brief discussion on scientific missions and the year 2015 being the Year of the Dwarf Planet.  He talked about the Dawn Mission and Ceres, New Horizons and Pluto, and the oceans on the outer planet moons.  Exoplanets and the habitable zone were also part of this discussion which included an assessment of just how our knowledge has changed regarding the compositing of the solar system.  To redirect the conversation to the purpose of today’s show, human spaceflight (HSF), I asked Brent when we would see HSF beyond LEO (BLEO). I asked about what seemed to be a new space advocacy push for space settlement. Brent then examined why HSF and referred us to his earlier work and the four reasons for HSF which were explore, exploit resources, to experience space, and settlement.  He said settlement was clearly part of the debate, talked about earlier workshops which would avoid the topic and then spoke to the recent Pioneering Space meeting held in Washington, DC where there was a consensus reach for space settlement.  He had good things to say about the meeting and the consensus resolution and talked about the broad space industry representation at the meeting as it was not just NewSpace.  Don’t miss what he had to say about it and space settlement.  Brent was also asked if our National Space Policy Act needed to be amended to reflect space settlement as the official goal of NASA.  Later, he was asked about the stepping stone or incremental approach to HSF development.  He supported this approach, spoke to the challenges for HSF such as life support and more.  As we were closing out the first segment, he offered us valuable insights on this topic so don’t miss what he had to say.

In the second segment, John from Florida called in to ask about grand space visions like an O’Neill orbital colony.  Brent proceeded to discuss grandiose visions in the context of how challenging they were plus their replacement cost.  Here, he used the replacement cost for Manhattan as an example of what he was talking about.  He cited a different type of example, the NASA Ames Space Settlement Contest that had nearly a thousand entries this year from 21 countries with the winner writing a 247 page grand space vision report.  Brent also spoke to the inspiration factor when talking about this contest.  A variety of listener emails were read on air for Brent to respond to, then I asked him if he thought Mars was the Holy Grail for HSF.  He said no so don’t miss why he said that.  He was asked about nuclear propulsion, then we talked about returning to the Moon , cislunar development, and then back to Martian settlement.  He was asked about going to the moons of Mars and he said there were two ways to settle Deimos.  Don’t miss his comments here either.  Near the end of the program, he said the physics of HSF were good but the problem was centered in being grounded in what he called program or budget math.  The budget math for HSF simply does not work, especially for a commercial venture.  He closed on the reality check of being grounded in budget math and the difficulty in going to Mars with humans.

Guest:  Robert (Bob) Zimmerman.  Topics: A variety of space news topics and projects were discussed on this two hour program.

We welcomed back Bob Zimmerman to the show for this 122 minute discussion on a wide range and variety of space news and project topics.  During the first segment, Bob spoke about Virgin Galactic and Launcher One delays, comparing it to the recent news that the AF will soon be testing a small satellite rail gun launcher, Super Strypi.  Bob suggested that the market might be passing VG by.  He also spoke to suborbital space both with VG and XCOR and true to form, was still skeptical about their potential success.  Some of Bob’s comments were challenged by listeners later in the show so stay tuned.  Next up Bob talked about the Russians opening up ISS tourism again in 2018 saying that the Russians believe the American private sector will be successful in transporting astronauts to and from the ISS by then so they will have available seats for tourists.  Don’t miss his comments on this subject.  He was asked about XCOR and he offered more comments on the company and suborbital space in general.  He then turned to the current round of ISS cargo bidding and compared it to the first round of cargo bidding a decade ago.  His comparison was most interesting and goes to the success being made by the developing commercial space sector.  Marshall was our first caller and talked about the next big planetary or HSF mission.  He also wanted Bob to discuss colonization.  Bob said he supported it but was realistic.  Bob then spoke about both the new Russian spaceport Vostochny and compared it to the progress being made by SpaceX and their new Brownsville spaceport.  He had much to say on this.  A listener emailed him to explain the space policy position of Sen. Ted Cruz.  That turned out to be quite a discussion, including Bob opining once again on SLS. Becky in Florida asked Bob about Mars One and Bob said it was a boondoggle.

 

In the second segment, Dr. Charles Lurio was our first caller.  Charles wanted to take Bob behind the woodshed on three points:  First, his comments on Kistler were wrong as the company was Rocketplane Kistler plus other details Bob missed. Second, he said Excalibur Almaz was not a fraud. This resulted in quite the exchange with Bob. The third area that upset Charles the most dealt with the comments Bob made about XCOR.  Charles was determined to correct the record on XCOR so again, don’t miss this exchange.  I asked Bob about the Indian space program and specifically their human spaceflight program.  Jerry from Florida emailed in additional info on Rocketplane Kistler.  SLS John called in to argue with Bob on his SLS comments.  I call their argument a draw with all participants including myself saying what we have been saying about SLS for years.  The subject of presidential leadership came up and Bob did his best to point out that it was probably a myth as far as space goes plus he cited supporting examples.  I pointed out that more than likely our next president, regardless of party, would have their hands full of solving major problems and I cited education as an example, referencing a recent survey I had seen showing just how poorly the US ranks worldwide in several educational areas.  This opened up a STEM discussion with Tim in Huntsville and Bob.  Jerry from Florida emailed in data showing that the Falcon Heavy would have more capability than SLS block one according to comments made by Ms. Shotwell at Satellite 2015.  This opened up another discussion on SLS, Falcon 9 and Falcon Heavy.  Here is an Aviation Week article that summarizes the comments Shotwell made at the event: http://aviationweek.com/blog/spacexs-gwynne-shotwell-talks-raptor-falcon-9-crs-2-satellite-internet-and-more.  Thanks to Jerry for providing us with this information and the article.   As the show was ending, Bob identified areas to watch for the second quarter and the balance of the year.

 

Please post your comments/questions on TSS blog above.  Bob can be reached through me or his email address provided in his bio posted on the archives on TSS website.

Welcome to this Open Lines program in which many space topics were discussed by those emailing and calling today’s show. During the first segment of our very long 2 hour 37 minute program, I suggested several topics for discussion including Gliese 581d, topics suggested by listener Kirk in a before the show email, the SpaceX vs. Blue Origin patent litigation, and the recently held Pioneering Space National Summit with space settlement and cheap access to space as the consensus goals of the summit. To begin the program I read an email from a Portland listener wanting information about Mars One. Our first caller was Michael Listner who explained in some detail the ruling recently handed down by the court regarding the SpaceX vs. Blue Origin patent challenge regarding landing a first stage on a floating barge and restarting the rocket engine. Michael did a great job in walking us through the decision, what it means and what to expect next so don’t miss what he had to say about this important case. Blue Origin was granted the patent in 2013. Marshall called to talk about this being the year of the Dwarf Planet with Dawn and Ceres plus later on New Horizons reaching Pluto. Jon from NJ called and we talked about communicating over interstellar space given the story I reported on regarding Gliese 581d 22 light years from earth. We lamented the amount of time it would take to send signals back and forth were it an inhabited planet. Jon thought there might be faster ways of communicating using packets of data. He also suggested a themed Open Lines show, “Confessions of a Space Cadet.”

In the second segment, Kelly Starks called and was extremely controversial. First, let me say that Kelly’s statements, perspectives and views are not those of The Space Show, One Giant Leap Foundation, or me, David Livingston. They represent only Kelly and nobody else. The controversy came when Kelly compared working for old space as compared to New Space companies and then accused NewSpace companies of cutting corners for safety, compromising designs, etc. I strongly disagreed with Kelly through the length of his call and at times cautioned him in making unfounded accusations against his former employer. He said he could back up his accusations but as you will hear, I was very skeptical of his ability to do that and told him so. Toward the end of his comments, he mentioned his old ArcJet space plane project which died for lack of funding, interest, and support. He called back before the end of the show getting in the last call of the show to tell us more about ArcJet plus I told him if he had any material on it that was handy, I would upload it to the blog. For those of you interested in Kelly’s ArcJet project, I have uploaded two of his papers to the blog for this specific show so you can download them as you please. John from Ft. Worth called in to give a different “spin” and take to Kelly’s comments but I was not really accepting of John’s take on what Kelly had to say. Doug called to also talk about dwarf planets and suggested we might be in a golden era of planetary science. He said the Ceres white spot might prove to be very interesting if its water. Doug and I also talked about his concept of going directly to the Moon. At first I misunderstood what he was talking about but in the end we were both on the same page as to what he had to say about the issue and I thanked him for clearing up my confusion over his comments. I asked him for his views on what Kelly had to say but for the most part he just said it was not something he was interested in.

Please post your comments/questions on TSS blog. For those of you wanting to take issue or support what Kelly had to say, civility is required when posting on the blog. Ideas can be held up to the light of day and are fair game. Any posts lacking civility will be removed from the blog.

Welcome to our Open Lines discussion.  In the first segment of this 2 hour 2 minute program, I put forth some suggested topics and once again, I explained phone line issues for listeners regarding land lines, VoIP, compression, cordless phones, cell phones, digital phones, and even fiber lines.  Phone line issues remain the number one problem faced by The Space Show in delivering quality audio so once again I went over the requirements and the restraints based on our equipment and broadcasting equipment in general.  Several listeners did comment on the phone line issues via email.  John from Florida was the first caller and he talked about Ernst Stuhlinger and his work plus he requested Dr. Jeff Hoffman of MIT return as a guest to the show.  During our conversation, I mentioned ULA CEO Tory Bruno recent & his lecture at Stanford on the pros and cons of rocket reusability (www.youtube.com/watch?v=9DMb2yHh5CA).  Marshall was the next caller who talked about cell phones and the DSP computer in the phone. He also talked about SOHO and replacing old satellites with new ones. We talked about the cost of doing that and Marshall said he would gladly pay 5% more in taxes if he was guaranteed the money would be used for satellite replacement. I asked other callers if they would do that but nobody bothered to respond.  Marshall said we needed a satellite replacement program so jokingly, I suggested a Cash For Old Clunker Satellites modeled after the Cash for Clunkers car program several years ago.  Michael Listner called to talk about recent news articles suggesting the FAA was going to regulate lunar business.  He clarified this for us.  Emmet sent us a note suggesting Doug had a video on the net which had gone viral thus making Doug an internet star (www.youtube.com/watch?v=Rzy63276GEg).

In the second segment, Doug called the show & explained the video as a product of http://www.moonandback.com.  Doug talked about the planned SpaceX launch later in the day, the recovery of the first stage and the Falcon Heavy as part of his overall heavy lift discussion.  He also raised some questions about the Dawn Mission and its potential findings regarding Ceres.  Turbo pumps came up as did other issues with liquid rocket motors such as which fuel to use given my promoting the late April webinar addressing these and other rocket issues.  Ken from Dallas called to talk about Moon Day set for July 18, STEM, and he also mentioned Asteroid Day set for June 30.  As Ken is a sci fi movie authority, we talked some movies and TV shows.  John from Ft. Worth called and mentioned a movie and the satellite being launched by SpaceX nicknamed the Al Gore Satellite for Climate Change.  John briefly mentioned The Telegraph article showing how temperature data had been tampered with and calling it the biggest scandal ever (www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fiddling-with-temperature-data-is-the-biggest-science-scandal-ever.html).  John put forth some growth and population statistics as part of his argument against global warming.  Other subjects mentioned during this open lines by listener emails included why there was no live streaming of the first stage recovery attempt for the Falcon 9, why drones were not suitable for live streaming as they were with the Orion flight, plus many listeners emailed in about Cash for Clunkers & old satellites and the projects and work of Ernst Stuhlinger.

Please post your comments/questions on TSS blog above. You can reach any of the callers or those sending email through me.

We welcomed Dr. Marc Rayman to the program to discuss the Dawn Mission to both Vesta & Ceres.  To find out more about Dawn, visit http://dawn.jpl.nasa.gov.  Also check out Dr. Rayman’s blog The Dawn Journal @ http://dawn.jpl.nasa.gov/mission/journal.asp.   Visit the DS1 site & archives by Dr. Rayman @ http://nmp.jpl.nasa.gov/ds1.   During the first segment of our 91 minute program, Dr. Rayman introduced us to the Dawn mission which first went to Vesta & is now closing in on its second destination, Ceres. We talked about the mission being specifically chosen to visit both Vesta & Ceres & that Vesta data is still undergoing analysis.  Dr. Rayman described Vesta’s Rheasilvia Crater 300 miles in diameter formed by an impact about one billion years ago.  We also talked about Vesta meteorites on Earth.  Dwayne called regarding competing theories about Ceres, planets having changed positions at one time, & Dawn mission limitations.  Perry wanted to know what information the team most wanted to get from Ceres. Dr. Rayman said they wanted to know basics such as what it looks like, what it was made of, ice, etc.  Other listeners wanted to know about Ceres compared to Mars access.  Here, Dr. Rayman had much to say as the subject came up again in the second segment.  Doug wanted to know about the large bright spot on Ceres plus other questions.

 

In the second segment, Dr. Rayman told us about his Dawn Journal (blog) per the above URL.  I asked our guest if he thought of Dawn & other science missions as competitive with human spaceflight missions.  Don’t miss his reply as I believe it was very special. BJohn sent several emails asking for Dr. Rayman’s favorite targets, especially for future missions. He also asked about using nuclear power rather than solar.  Our guest described the solar arrays & why solar was chosen for Dawn.  Ion propulsion came up & was a major discussion topic for the balance of our program.  Dr. Rayman described how ion propulsion worked, why it used a slow but steady acceleration, & its advantages over chemical propulsion.  Matt asked about RTG development for future missions .  Doug sent us another question based on the low Ceres gravity & landing on Ceres to pre-position supplies in advance of a crew.  Our guest pointed out it was far more complicated than Doug implied given that the Ceres orbit was tipped more than 10 degrees from the ecliptic.  Make sure you hear this explanation.  Among the many questions Matt asked, he wanted to know about the German component of the Dawn mission.  As we approached the end of our show, Dr. Rayman gave us a preview of what to expect as we get very close to Ceres, gradually getting as low as Earth & ISS.

John Batchelor and I welcomed Dr. Jeff Foust back to Hotel Mars. During our 12 minute Hotel Mars segment, we talked about significant space events and missions during 2014 including the recent methane discovery on Mars, Curiosity findings, Space X & Orbital Science 2014 events, the Rosetta mission, New Horizons to Pluto, and the Dawn mission. Virgin Galactic’s accident was reviewed as was the Antares rocket motor explosion and Orbital making an agreement to get new RD 181 Russian rocket motors for Antares. Also discussed was Venus Express and recently launched Hayabusa 2 mission. Jeff provided us with updates on all of these missions and companies.

We welcomed Dr. Alan Stern back to the program to discuss New Horizons which is on target for its summer rendezvous with Pluto and new Uwingu projects relating to Mars (www.uwingu.com).  During our hour long program, Dr. Stern started with New Horizons and he mentioned the 10 AM PDT, 1 PM EDT NASA press conference today regarding New Horizons passing Neptune’s orbit plus it being the 25th anniversary of Voyager passing the Neptune system.  The press conference is at http://www.space.com/17933-nasa-television-webcasts-live-space-tv.html but if you miss it, I’m confident it will be archived.  Alan reported that New Horizons was in good health, we talked about the course corrections it has made along its trip to Pluto, plus special events planned for its arrival in the Pluto system.  Other topics included the Kuiper Belt and Ort Cloud, dwarf planets and just how many planets are in our solar system per a question asked by a listener regarding his son’s science class.  BJohn asked questions about the Gaia telescope and comparisons of New Horizons to Dawn and the Rosetta mission.  Another listener asked about the New Horizons team and its costs so far.  We talked about the need for advanced propulsion and what missions would be most suited for it.  Doug sent in an email regarding Pluto, Ceres, and the start of a new era of exploration.  Lots of comments and questions about Pluto being a planet as Alan referred to Pluto as a planet.  Dr. Stern did go over the differences and similarities with Rosetta, New Horizons and the Dawn Mission and he said the Gaia telescope could not do the imaging Bjorn asked about but that Earth-based telescopes could do a good job in some circumstances s could Hubble.  At the halfway point, we switched over to talking about Uwingu and their latest Mars project (see http://uwingu.com/beam-me-to-mars).  I mentioned on air about a Space Show contest which would award the winner a message to Mars so if you have ideas for such a contest, email them to me please.  I plan on sending a Space Show message to Mars and will post it on the blog.  Alan also talked about the program naming Mars craters which will appear on their Mars map which is planned to go to Mars on the Mars One robotic mission in a few years.  Before the show ended, a listener asked Alan about the Next-Generation Suborbital Researchers Conference.
