http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  We welcomed Dave Reneke to the program to discuss all space issues from the Australian perspective.  Find out more about Dave, his space and astronomy work, plus sign up for his free newsletter at www.davidreneke.com.  Starting out, I asked our guest about the Perth radio telescope used by ESA that seems to be the only location making some contact with the Russian Phobos-Grunt mission.  After talking about Perth and its geography, our guest mentioned the competition for the Square Kilometer Array Telescope (SKA) competition which has been narrowed down to the Australian location or a location in S. Africa.  Dave mentioned the SKA telescope and its capabilities throughout our discussion.  As we learned, the Perth area is actually quite quiet regarding radio noise and a good location for the radio telescope array.  Dave received email questions about the space awareness level of the average Australian as well as for his students.  Having been to the U.S. several times, our guest said that there was not much difference between Australians and Americans when it comes to space awareness and knowledge.  We also talked about commercial space, space tourism, and our current American space policy.  Josh asked about the difference in the night sky from the southern hemisphere view as compared to what most of us see here in the northern hemisphere.  Dave gave us some good comparison notes which I think you will find interesting, especially about the Southern Cross, some of the planets, the Big Dipper, Orion (the Swordsman in Australia), and even the Milky Way.  We talked about national television coverage in Australia of the recent MSL launch, and then some more about issues facing the U.S. space policy of today.  In our second segment, Dave got a listener question about Australian concern and coverage for space debris falling to Earth and he reminded us about Skylab coming down in Australia and told us some interesting stories about it.  I asked him about the Air Force UFO article on his website.  He had much to say about it and his previous work as a UFO investigator.  We then switched to talking about deep space, Pioneer 10, and SETI searches.  We mentioned the potential water planet discovery, Gliese 586g, and much more.  Dave was asked when the effects of our sun cease and a deep space mission starts having effects from a different solar system or from being in deep space.  Dave talked about a region of turbulence hitting Pioneer 10 and suggested deep space really starts when our solar system effects end. He referenced the heliosheath. We also talked about the Voyager Interstellar Mission.  Dave told us a few stories about Apollo 11 that he learned from his day long meeting with Buzz.  He concluded with a long term hundred year vision suggesting that eventually there will be travel beyond the speed of light with routine space travel.  Post your comments/questions on the blog URL above. Dave can be contacted through the Contacts page on his website.

Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Matthew (Matt) Kleiman to the show to discuss his recent TSR article, “Protecting Apollo artifacts on the Moon, written on November 7, 2011. You can read the article at www.thespacereview.com/article/1961/1.  We began our discussion by describing the Apollo artifact situation, explaining ownership of them per the Outer Space Treaty in that there is no space salvage law.  He said NASA recently issued guidelines for protecting the Apollo artifacts given the likelihood that private companies and possibly other nations might get to the sites, disturb or alter them, or even contaminate a few of the ongoing experiments that are still functioning.  As you will hear, the guidelines are not enforceable, they are voluntary, and  you can find them at www.collectspace.com/news/NASA-USG_lunar_historic_sites.pdf.  We spent a major part of this segment talking about the guidelines and related issues.  Also discussed were liability issues and the problem with determining negligence regarding space activities.  A listener asked about the timing of the NASA guidelines announcement given that at least for now, we are unable to return to the Moon.  Matt then separated out robotic missions to the Moon as compared to humans returning to the Moon.  Our discussion also took us to the issue of property rights on the Moon and elsewhere in space.  We started the next segment by asking Matt about the Moon Treaty and its status.  We talked some more about salvage law for space and addressed the issue of why the US prefers to use international law for protecting the sites rather than doing it unilaterally as that raises potential sovereignty issues posed the by the space treaties.  Phobos-Grunt came up with regards to space debris issues.  During our space debris discussion, we talked about liability, the fact that an individual cannot bring an action other than through his/her country (the State Department for U.S. citizens) and more.  Matt talked about and described the Reasonable Person Doctrine.  A listener asked about the Google Lunar X-Prize and Matt briefly talked about the Draper programs with two teams.  He also told us about the long standing Draper Labs participation in our space program and that Draper Labs was the first non-government Apollo team member.  Another listener asked about the common heritage of mankind language in the Moon Treaty and to a lesser degree in the Outer Space Treaty.  Toward the end of our discussion, we talked about the challenges for making new treaties and the concepts/programs being used to accomplish nearly the same as a treaty but using a process other than a treaty.  If you have questions/comments, please post them on The Space Show blog URL above.  Matt can be emailed at matthew.kleiman@gmail.com.

Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  We welcomed back Marcia Smith of SpacePolicyOnline.com to discuss the recently passed Minibus FY 2012 NASA budget as well as some of the issues for space policy as a result of the failure of the Supercommittee.  Here are some specific URLs from SpacePolicyOnline.com that you will find useful for this discussion as well as understanding what is going on:  1) Re the Minibus:   www.spacepolicyonline.com/pages/index.php?option=com_content&view=article&id=2008:minibus-signed-into-law&catid=67:news&Itemid=27; 2) Re the Supercommittee: www.spacepolicyonline.com/pages/index.php?option=com_content&view=article&id=2016:the-day-after-whats-next-for-nasa-after-the-supercommittee-failure&catid=67:news&Itemid=27; 3) The NASA FY 2012 Budget: www.spacepolicyonline.com/pages/images/stories/NASAs_FY2012_Budget_Request.pdf.  We started our discussion with the statement that we are in “unchartered territory.”  Ms. Smith described the Poison Pill which goes into effect from 2013-2021 regarding pending budget cuts which will be significant but are not clearly understood at this time. There might be a 7-8% across the board cuts.  The cuts also impact discretionary spending, not just defense or some entitlement programs.  Ms. Smith explained this to us so don’t miss the discussion.  NASA’s FY 2012 budget was down about 4% from what the President sought.  Commercial crew was cut by about one-half to $406 million. Marcia confirmed that thought is being given to funding only one commercial company due to the reduction in funding. We also discussed the current pricing for buying rides on the Soyuz to the ISS as compared to the current pricing quoted for the Space X Dragon.  Other topics in this segment includes SLS, MPCV and crew transportation in general.  We talked about funding for the SLS and the James Webb Space Telescope (JWST) in the FY 12 budget.  Ms. Smith reported to us that NASA Administrator Bolden recently testified that the three top priorities for NASA were SLS/MPCV, ISS, and the JWST.  Marcia was asked about the OMB and their role in the budget process, specifically concerning future Mars missions.  In our second segment, we talked more about the Minibus bill and some of the specific funding project within the FY 12 budget.  Dave called in with a most interesting perspective on the issues from within NASA, asking us to focus on more than just the budget lines.  Don’t miss what Dave had to say.  As we approached the end of the program, we talked about DOD and National Security Space Policy  using NOAA and the DOD NPOESS satellite programs as an example of the challenges ahead.  Please post your comments and questions on The Space Show blog URL above.

Guests:  Open Lines with Dr. David Livingston. Topics:  Space Show December schedule changes, Phobos-Grunt, MSL, OMB & Mars missions, Space X, NASA policy, human spaceflight & more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.

Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  Welcome to our Open Lines discussion.  We started the discussion with a few announcements. First, I talked about the Droid smartphone podcast timing issue that a few listeners have called to my attention.  For those experiencing this timing issue, I hope the information shared with you from other listeners was helpful. Please let me know either way. Also, listener Theron emailed me as I was preparing the archives and said “Google Listen after the show stops you can go back to the pod cast and it will start up again where it last stopped. They can also go to live 365 and listen there with no problem or listen to the archives and do the same thing.”  I next talked about my December 2011 schedule which is going to be weird to say the least given my need to be in S. California for a good part of the month for family and medical reasons.  Please listen to the discussion on the probable changes for the month and check the website newsletter as I will update everyone on live and replay programs & the use of the toll free phone line when I have updated information.  The first listener question after the announcements asked for my opinion on being able to save Phobos-Grunt (P-G) and the upcoming MSL launch scheduled for Saturday morning.  Regarding the Russian Mars venture, I was not optimistic about its success but like everyone else, I remain hopeful. I then mentioned some of the various blog comments I have seen on P-G and why most of the comments were absurd, showing a total lack of understanding of basic physics and engineering & the P-G mission architecture.  Our friend Charles called in to talk about the science missions of NASA & to offer his perspective on the human spaceflight part of NASA. He brought us current with the N-Prize and his Microlaunchers program.  He got a question asking for his perspective on the Google Lunar X-Prize. Charles & I disagreed as Charles does not think anyone can win it or be successful.  Charles addressed the blog comments re P-G which I mentioned earlier as Charles does understand the science & engineering involved in a space mission.  When we returned from our break, Arnie sent in an email about the OMB possibly killing future Mars mission. I read excerpts from a news release on the issue.  John called in, said we were in a space survival mode. He wanted to know more about the blog article by Trent, “The Case Against Space X.”  Making it clear that I disagreed with Trent, I read excerpts of his article on air as The Space Show airs all sides of issues regardless of my position on the issue.  I do hope Trent turns out to be wrong.  I suppose we will find out in time as Space X and our program continues it evolution.  John asked Charles a question about space debris from his Microlaunchers idea. Charles replied by email saying “main ML missions are to the space between orbits of Mars, Earth. Literally trillions as much space as LEO altitudes. Space exploration begins beyond escape.”  Please post your comments/questions on The Space Show blog URL above. If you have Droid suggestions, do put them on the blog.  December scheduling or fundraising questions, please email me.

HAPPY THANKSGIVING!

 http://archived.thespaceshow.com/shows/1659-BWB-2011-11-23.mp3

Guest:  Dr. Dwayne Day.  Topics:  The future of the U.S. astronaut corps & the Chinese space program & intentions.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Dr. Day back to the show to discuss the NRC/National Academies report he directed, “Preparing for the High Frontier: The Role & Training of NASA Astronauts in the Post-Space Shuttle Era.”  You can download this report in .pdf format for free: http://www.nap.edu/catalog.php?record_id=13227.  Later in the program, Dr. Day talked about the Chinese space program based on his Space Review article from Nov. 14, 2011, “Staring into the eyes of the Dragon ( www.thespacereview.com/article/1970/1)”.  We started our discussion talking about the astronaut corps of the future.  Dr. Day told us about the study panel members,  their methodology, their visit to JSC in Houston to see the training facilities, & their discussions with many of the commercial companies working on CCDEV. Their initial assumptions that were proven wrong were that NASA had too many astronauts & the use of the T-38 were not that vital to the program. They discovered that the astronaut corps had already been downsized. Dwayne provided us with a chart which is on the blog for this program showing the astronaut corps population going back to 1959 projected to 2016.  The panel looked at three issues at the start of their task: The future role of the corps & its size; Training facilities & needs post shuttle; Training aircraft such as the T-38 for spaceflight readiness issues.  During this segment, Dr. Day discussed their work & conclusions in detail.  Several questions were about comparing the U.S. astronaut program with the Russians & the training involved with astronauts from other countries.  Many listeners wanted to know about the role of commercial launch providers & even if there might be a private astronaut corps.  One of the things Dr. Day said was that two commercial astronaut models were being examined by NASA, the rental car model & the “we are in charge” model.  He also talked about the impact on the program, planning, & development of uncertainty.  As for the T-38s, the conclusion was that they were needed for real time space situational awareness training & decision making. In our second segment, Dwayne took a few New Space focused questions.  He mentioned talking to Space X & other companies plus what his panel heard as to their suggestions for the astronaut corps.  Later, we talked about NRC reports in general, avoiding conflict of interest, & taxpayer value. A listener from Canada asked about the possibility of a private astronaut corp returning to the Moon before government astronauts. This led to a discussion about space enthusiasts & reality checks.  For the balance, we talked about the Chinese program.  Here, Dr. Day broke it down between human spaceflight & their defense, science & image satellite programs. He also talked about Chinese intentions.  I urge you to read his excellent Space Review article referenced above.  For 2012, I will do my best to offer Space Show listeners programming on the Chinese program, including webinar panel discussions, as it is important for us to understand as much as possible about the Chinese program.  Post comments & questions on the blog URL above.  You can email Dr. Day at zirconici1@cox.net.  If you do email him, please copy me so I can learn from the exchange.

Guest: Dr. John Brandenburg.  Topics:  We discussed his new book, the GEM Unification Theory, gravity, propulsion and more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  The Space Show/OGLF is now engaged in its annual fundraising drive. Please check out our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  We welcomed Dr. John Brandenburg back to the program to discuss his new book, “Beyond Einstein’s Unified Field: Gravity & Electro-Magnetism Redefined.”  I urge you read his paper published in the Journal of Cosmology. “A Derivation of the Newton Gravitation Constant and the Proton Mass From The GEM Unification Theory of Baryo-Genesis” at http://journalofcosmology.com/JoC17pdfs/brandenburg2.pdf. Dr. Brandenburg & I have been friends for a very long time & our discussions are informal, sometimes meandering, & always great fun. At times this discussion was heavy into the physic so do bear with us.  In segment one, Dr. Brandenburg said that the GEM theory was a “theory of most stuff.”  He referred to the Gravitational Constant & the Planck Scale as well as the Middle Scale throughout the discussion. He provided the groundwork relating to Einstein and quantum mechanics, hidden dimensions, string theory, the 5th dimension, electro-magnetism & gravity theory.  He also referenced many times over the Kaluza-Klein theory & work by Sakharov.  An early question asked our guest to explain why there were different intensities of gravity on different planets.  Dr. Brandenburg talked about Big G, all matter being electromagnetic at the molecular level & ratios (with Earth)  used to predict the surface gravity of a planet made of rock.  In our second segment, Dr. Brandenburg went into more detail about his GEM theory which is also referred to as the Grandis et Medianis theory.  The Big Bang was discussed as well as what happened in the second before the Big Bang.  He also talked about string theory & its relationship to the GEM Theory.  A listener asked about the recent faster than light neutrino experiments. The experiment named OPERA was very simple & basic & most interesting.  In discussing this experiment & its results, he introduced us to tachyons which prompted a call from listener John in Atlanta & they spent some time discussing the physics of the GEM theory & what it might mean for propulsion.  To simplify this review, we now move forward to the need for portable fusion power & using gravity modification for space transportation.  While optimistic for gravity modification, Dr. Brandenburg was blunt in saying that without portable nuclear power, even with gravity modification, we would not leave the atmosphere & we would continue using big chemical rockets.  Don’t miss this discussion. We talked more about string theory & dimensions & then a listener asked about parallel dimensions.  Dr. Brandenburg had much to say on this topic as well. Near the end of our two hour discussion, I asked our guest about his next book & this opened up a different discussion line. Dr. Brandenburg is going to write about science, religion, the Middle East, Israel, ancient history, Greece, the Roman Empire & metaphysics before physics!  Look for him to be a guest on the show about this one.  We ended our show talking about thorium, thorium reactors, why thorium cannot be used for weapons, & natural nuclear events in Africa & on Mars which he discussed in detail when he was last on The Space Show.  Post your comments/questions on The Space Show blog URL above.  John can be emailed using brandenburgj@orbitec.com.

Guest:  Mark Whittington.  Topics:  An overview of the space development, exploration, financial, and policy at this time, civil and commercial.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed back Mark Whittington to the program.  Mark’s blog, Curmudgeons Corner can be read at http://curmudgeons.blogspot.com.  In starting our discussion, I asked Mark for his assessment of space policy, space development, commercial space, and space markets as of today. Also, issues surrounding capital acquisition.  The word that came to mind in giving us his take on things was dysfunctional.  Mark then talked about the recently passed NASA Minibus FY 12 funding bill which provided NASA with a $17.9 billion but reduced commercial crew to $406 million.  We talked about the impact of this funding level on commercial crew and possibly only selecting one company to be funded.  We talked about SLS, the James Webb Space Telescope (JWST), and the expected outlay for two years of buying rides to the ISS on the Soyuz.  Returning to the Moon came up and Mark provided us with updated information from the Europeans because for them, returning to the Moon is a priority.  Other issues discussed in this segment included astronaut safety, NASA risk taking, low cost space access, and a comparison of astronaut risk to military fighter pilot risk.  Mark then introduced us to predatory budgeting which he discussed in the context of SLS.  At the end of the segment, Mark had some things to say about the Phobos-Grunt mission and the Chinese space program.  In the second segment, Mark provided us with a short summary of the space policy, as much as it is known, for those seeking the office of president next year.  He spent the most time on Newt’s probable space policy because the most is known about his policy.  He also talked about the space policy for President Obama in another term or from Hilary were she to replace Mr. Obama on the ballot.  It is an interesting overview, limited only to their space perspectives and nothing else.  Next, Mark talked about space advocacy and some problems he sees with it.  As we were nearing the end of the program, Space X was a discussion topic along with some of the other developing commercial companies.  He talked about problems associated with taking government money.  One of the final listener questions dealt with a big dumb booster, Mars Science Lab, and the Curiosity rover.  Please post your comments/questions for Mark Whittington on The Space Show blog URL above.

“2033 The Nuclear Mission To Mars”

http://archived.thespaceshow.com/shows/1656-BWB-2011-11-20.mp3

Guest:  Dave Ketchledge.  Topics:  Using nuclear power to do a humans to Mars mission.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed back Dave Ketchledge to discuss his new book, “2033 The Nuclear Mission To Mars.”  The books is available in pdf format on a CD.  You can order the book from this website, http://rocketengineer.bravehost.com.  Later in the discussion Dave mentioned that the book can automatically download to a Nook e-reader and can be converted to be read on a Kindle.  We started our 2 hour plus discussion with Dave providing us with background as to why a humans to Mars mission was important, why we need heavy lift, SLS, and why nuclear propulsion was essential.  He shared reasons with us for going to Mars and talked about a Mars mission as being in our national interest.  We took listener phone calls asking for a clearer explanation of why we need to go to Mars.  One listener asked about the artistic side of the Mars flight, taking our focus away from technology and engineering. Terry wanted to know how many missions could be gleaned from a nuclear rocket and our guest spent considerable time going through the needed nuclear technology, providing us with a basic understanding of the technology, the risks, etc.  In fact, several times during the segment, Dave reiterated why a manned Mars mission was so vital to our nation & future. In our second segment, Dave continued taking us through the various chapters in his book and talked about radiation doses for people, space travel, NASA and more.  Fred, a space medicine radiation specialist, emailed in a note disagreeing with some of what Dave was saying about radiation doses.  Dave said Fred was partially correct, disagreeing with some of Fred’s comments. This exchange prompted Tim to call in objecting to negativity & naysayers such as Fred (in his opinion). I called Tim on this which caused me to do one of my notorious rants against la la land thinking & bad assumption making  I since apologized to Tim for my outburst, but strongly oppose la la land thinking & assuming valid disagreement to be the same as being negative, including assigning emotions to commonly used terms in science, medicine, and policy discussions such as “controversial.” Later in the segment, I asked Dave to explain the difference between nuclear electric and nuclear thermal propulsion.  Throughout the discussion, Dave advocated for the NERVA type  nuclear thermal engine.  He also explained the advantages re ISP via Pebble Bed technology.  As we neared the end of our discussion, Dave talked about the structure of his book, the references & data base along with the Orbiter freeware he has included with the CD.  At the end of our program, I asked Dave to give us a 5 minute talk were he to be invited to testify before Congress on nuclear propulsion & a manned mission to Mars.  I thought he did an excellent job in his off the top of his head 4.5 minute talk.  See what you think.  Post your comments/questions on blog URL above.  Dave’s email address is in the lower left hand corner of the above website used for ordering his book.

Subject:  Space Debris Removal

http://archived.thespaceshow.com/shows/1655-BWB-2011-11-18.mp3

Guests:  Dr. Lucy Rogers, Franz Gayl.  Topic:  Removing Orbital Debris.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.   We welcomed back Franz Gayl and first time guest Dr. Lucy Rogers to discuss their recent Singularity University Space Team Project Final Technical Report:  “Removing Orbital Debris: A Global Space Challenge.”  For more information about their project and the debris issue, visit their website which is www.spacedebrisresearch.com.  Our guests also referenced the recent National Research Council (NRC) report on the subject, “Limiting Future Collision Risk to Spacecraft: An Assessment of NASA’s Meteoroid and Orbital Debris Programs.” Download the .pdf for free at http://www.nafwa.org/components/com_feedpost/feedpost.php?url=http://feeds.nap.edu/~r/nap/new/~3/0Wdaei5RGqE/catalog.php&site=Nutrition%20and%20Food%20Web%20Archive.   During our first segment, our guests introduced us to their Singularity University project and the problem of space debris.  They provided us with statistics for debris pollution in the most popular orbits, including polar orbits.  We talked about high orbits, MEO & GEO orbits & new satellite mitigation techniques to either bring a satellite down much faster or to move it to a higher parking orbit out of the way freeing up the actual orbit for use by another satellite.  We talked about those most responsible for space debris which are the U.S., Russia (former Soviet Union) & China.  Responsibility for cleanup lies with these countries by treaty but as you will hear, its not always easy to know which piece of debris is the responsibility of which nation state.  Later in the segment, a listener asked about the Kessler Syndrome which our guests addressed, then we talked about reentering satellites, especially from LEO.  The issue of national security for satellite location/identification came up & as you will hear, this is a major issue yet to be resolved in international debris negotiations.  In response to questions about why we don’t have debris removal efforts with budgetary priorities, Franz talked about human nature & why it is so difficult to take action before an event actually happens.  In our second segment, Dr. Rogers talked about the need to establish a trade association with all the stakeholders to work out solutions to the debris threat as it is possible that within five or so years, debris collisions could wipe out important security as well as commercial satellites.  Beth asked about space tourism being at risk. Our guests said it was, specifically orbital space tourism. Another listener asked about planetary protection & the working together with groups addressing planetary protection along with debris issues.  Toward the end of our discussion, an Economist online article was mentioned.  You can find this article on their website in the media section http://www.spacedebrisresearch.com/Space_Debris_Research/Media.html. Scroll down until you see the Economist Online article listed from Sept. 1, 2011 www.economist.com/blogs/babbage/2011/09/innovation). The article talks about the third graduating class from the Singularity University & all their projects, including AstroTrash which was the project submitted by our guests.  Other discussion topics suggested by listeners included the likelihood of a commercial company being formed to clean up space junk as well as a host of questions about international legality in space debris cleanup.  Please post your comments/questions on The Space Show blog URL above.  Dr. Rogers and team members can be reached at info@spacedebrisresearch.com
