We welcomed Dr. David Crisp to the show to discuss the NASA Orbiting Carbon Observatory-2(OCO-2) satellite. During the first segment of our 94 minute program, Dr. Crisp started out by presenting a short overview of the OCO satellites, the first two of which did not make it to orbit due to fairing failure after their Vandenberg launch. For the third attempt, NASA switched rockets to the Delta 2 and the satellite made it to orbit without a problem. Dr. Crisp then explained how OCO-2 works, how it detects and measures CO2 in the atmosphere from the ground up. He explained the color intensity and why the information is so accurate. I asked him to compare OCO-2 data with climate models. Here, Dr. Crisp stressed the fact that he was not a climate scientist or policy maker. That said, he did compare and contrast OCO-2 data with climate models to the degree reasonable comparisons can be made. We talked about natural sources of CO2 on earth, both land and water (ocean, rivers, and lakes), as compared to manmade sources of CO2. Dr. Crisp explained the emitting and absorption capabilities from the natural CO2 sources, photosynthesis with plants, and the fact that manmade CO2 is only emitted, not absorbed. This CO2 can stay in the atmosphere for a thousand years or so. He talked about the total parts per million of CO2 in the atmosphere, how it has gone down and now is going up over the years and the amount of human created CO2 in the atmosphere and how that has increased over the years. Listeners asked about methane but OCO-2 was not designed to detect methane. He was also asked about water vapor. Dr. Crisp explained that water vapor in the atmosphere was detected and measured by other satellites, particularly weather satellites so it was not part of this genre of satellites. Jack emailed in a question to point out that a pause was going on for the past 19 years or so and the planet was not cooling despite human CO2 increases. Dr. Crisp offered an explanation for the pause so don’t miss it.   Jane from Seattle brought up the fact that warming and cooling on Earth has been going on since the beginning of time, without human produced C02. She asked how this could be given the conclusions many make regarding the increase in human produced CO2 levels for today causing global warming. Don’t miss how Dr. Crisp responded to Jane. Dr. Crisp also talked about solar warming and cooling cycles and said we are currently in a solar cooling cycle. Randy emailed in a question about the draught in California and its relationship to CO2 increases.

In the second segment, Becky in Las Vegas sent in a note asking about the climate and atmosphere on Venus and Mars given our guest has studied both planets. She was looking for a common link with Earth or maybe a common trend. Dr. Crisp had much to say about both Venus and Mars. Later in the discussion, I asked if humans were on Venus with advanced technology, could they have intervened in the global warming process and mitigated the impact of it. He said he doubted it, explained why and then the same question was asked about Mars though the situation on Mars was and is different than on Venus. For the most part, Venus was too close to the sun to do anything about it and Mars was too far to do anything about the Martian problems. This is why Earth is in the Goldilocks zone and why we search for exoplanets in this zone. Later, Dr. Crisp talked about today having the highest CO2 levels ever and the growing Earth population which is around 7.2 billion people having nearly doubled over the last 45-50 years. This led us to a discussion about energy, including coal, natural gas & nuclear power. He had some surprising comments about China and coal, don’t miss them. We also talked about India and its use of coal, then Dr. Crisp talk about the need to be able to store power, use solar and wind power, and to enlarge the grid to take wind or solar from areas where it was strong to be able to ship to areas that needed it. He also talked about the need to improve energy storage. Near the end of the program, I asked about any surprises discovered from the OCO-2 data. We then talked about how long OCO-2 would last and here, we talked about the design as a demo satellite without redundant or backup systems. A listener asked if cubesats could do such an OCO-2 type mission. Don’t miss his answer but the simple one was no because the technology for doing this requires hardware that is considerably larger than could be used by a cubesat. Before the show ended, we talked about the NASA Earth Science Budget, the cost per taxpayer, and our ability to freely download OCO-2 data off their website. He then identified the largest user and downloader of the data. I bet you will be surprised by what he said. NASA was the second largest downloader of the data.

Guest:  Dr. Donald Rapp.  We discussed using indigenous resources to facilitate HSF to Mars, then the great climate change debate based on facts not agendas.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed back to the show Dr. Donald Rapp to discuss two important topics.  In the first segment we addressed using indigenous resources to facilitate human spaceflight to Mars and the MOXIE experiment on Mars 2020.  In the second segment, Dr. Rapp examined the climate change debate without out preconceived belief systems by an honest examination of the data.  To start our first segment, Dr. Rapp talked about the massive amounts of propellant needed for a human mission to Mars which then led us to discussing using resources on Mars to make propellant for the return to Earth.  Our guest was asked about going to Mars via the Moon and using lunar ice to make propellant for the Mars mission.  This proved to be quite a mini-discussion as Dr. Rapp was skeptical about the use of lunar resources including water ice as an assist for a manned Mars mission.  Many listeners asked him challenging questions about his position and conclusions do don’t miss this important discussion.  Later in the segment a listener asked Dr. Rapp about the potential benefits of using nuclear power and nuclear propulsion.  This too was a fascinating mini-discussion so don’t miss it, especially the call on the subject from listener Kris.  Dr. Rapp was asked about the MOXIE experiment which we talked about at length, then he was asked about the need for heavy lift rockets to Mars.  Our guest supported heavy lift which he defined as a 100-120 tons to LEO.

 

In the second segment, climate change was our main topic.  Here he talked about extreme agendas by both the climate alarmists and the climate skeptics and said a new group was emerging which he called the “lukewarmists” who actually and honestly evaluated the data without a preconceived belief system.  Dr. Rapp went through the known facts, the history of the subject, the warming periods, the CO2 levels and where on Earth warming mostly took place though there has been no warming from 1998-2015.  We talked about sunspots and climate change and the impact of El Nino and La Nina.  He also talked about global energy usage and the projected increases for the 21st century and beyond.  The increasing use of power and pollution by China and India were important factors in this discussion.  Listeners had many questions for him including many wanting a way to deal with excessive, costly and unscientific regulations that are forced on the people by politicians who don’t know the facts and have an agenda to their behavior.  No solutions were offered.  A teacher wrote in about the challenges she has teaching factual climate change to her students because parents on both sides of the issue come in and complain that the “truth” was not being taught in the class.  Dr. Rapp offered us concluding remarks around the basic idea that everything is complicated including sending humans to Mars and dealing with climate change issues.

We welcomed Dr. Heather Knutson to Hotel Mars for our discussion about Exoplanet HAT-P-11b given it has been discovered that this planet has clear skies and water vapor in its atmosphere. Dr. Knutson explained how clear skies and atmospheric water vapor was confirmed, what it means for this specific Neptune size exoplanet and what it means for our planet searches in general.  We talked about it having a hot atmosphere, a core but not a solid surface.  The exoplanet is not habitable.  HAT-P-11b is 120 light years from Earth.  Dr. Knutson also explained why so many exoplanets have a cloudy atmosphere and why that limits our research into the exoplanet.

We welcomed Bob Zimmerman back to the show for this one hour 55 minute discussion starting with the announcement regarding climate change and the upcoming IPCC report which has been leaked to the press.  The primary topic for this first segment was climate change, the leaked IPCC report and an analysis of it.  Bob fielded listener comments and questions including Marshall’s who had hands on experience with the very first computer climate model in the early 70’s.  Bob summarized all his comments saying that science needed to be skeptical and he was optimistic that skepticism was coming back to the field of climate science.  We then switched to space and NASA for the balance of this program.  As a transition, Bob talked about solar activity and the solar max.  In response to a listener question, he commented that if Mars or anyplace in space were developed using the Antarctica model, it would doom commercial space activity.  He stated over and over again that the model needed was the profit model for space and planetary development.

In the second segment, we talked about new commercial contracts for Arianne 5 recently announced, and how important these were to Arianne who needs to show a profit for the first time.  I asked Bob about NASA’s Redirect Asteroid Mission given all the attention it got last week at AIAA Space 2013.  Bob had much to say about this mission, most of it not supportive or positive, and then I mentioned the NASA press conference which is archived as part of the Space 2013 taped interviews and the fact that it is to be SLS dependent. This started Bob and others on SLS rants, mostly not supportive of it, and also Orion.  Bob was emphatic that Orion with SLS would not be a deep space mission & at one point he cited comments by Russian that their next generation Soyuz would have bathroom facilities on board and Bob said with Orion, it was strictly diapers for the crew.  We talked about Inspiration Mars and Mars One.  Bob was skeptical about both happening. Listen to the reasons he cited for his perspective.  Bob also talked about Bigelow Aerospace and its potential, listeners asked about Planetary Resources and the Redirect Mission, then we talked about the need to lower the launch costs to LEO.  Bob brought us current with SpaceShip2 & the latest powered demo flight, then John called in to argue about SLS with Bob.  This was an interesting give and take.  As Bob has done on other programs, he continued saying he does not want a space program which is a government program which in his eyes is doomed to failure.  He wants the private sector to prevail.  As the show was ending, I asked Bob for this thoughts on the budget, CR, and future commercial crew funding .
