Has the Great 'Moonrush' Begun? (thespacereview.com)
This week The Space Review published an essay by retired aerospace engineer Gerald Black, who worked in the aerospace industry for over 40 years and tested various rocket engines, including the ascent stage engine of the Apollo lunar module.
"The Moonrush is now on," he argues "fueled by entrepreneurs dreaming of profits from Earth's nearest neighbor." Leading the Moonrush are a bunch of private companies developing small lunar landers and rovers to explore the Moon. On February 21, the first mission of the Moonrush embarked aboard a Falcon 9 rocket.
The Beresheet lunar lander built by Israel's SpaceIL was launched as a secondary payload, sharing the ride with the Indonesian communications satellite PSN-6. After reaching geostationary transfer orbit, Beresheet and the communications satellite separated from the Falcon 9 launcher. The communications satellite will propel itself to geostationary Earth orbit. Meanwhile, Beresheet is slowly raising its orbit. In early April the spacecraft will enter lunar orbit, then land on the Moon. Israel Aerospace Industries, the company that built the lander for SpaceIL, announced plans in January to partner with the German company OHB to offer a commercial lunar payload delivery service to the European Space Agency.
Black also notes that while Google never awarded its $20 million Lunar X grand prize, many teams are still active, including Astrobotic Technology, Moon Express, ispace inc., TeamIndus and PTScientists -- and that NASA will be awarding $2.6 billion in commercial moon exploration contracts over the next decade under its Commercial Lunar Payload Services program. The first mission under this program could be launched as soon as late this year... Blue Origin is developing a much larger lunar lander called Blue Moon that can land several metric tons of cargo on the Moon. And the German companies OHB and MT Aerospace have tapped Blue Origin's New Glenn rocket and Blue Moon lander to ferry a payload to the Moon in 2023.
Around-the-moon tourism could begin as soon as 2023, Black writes, while Bigelow Aerospace's CEO "is dreaming about establishing facilities on the lunar surface that could host tourists and others." And finally, landers and rovers will soon confirm whether there's accessible water hiding in the moon's perpetually dark craters -- and will hunt for other valuable resources. Rovers that include sample analysis laboratories like the one aboard the Curiosity rover on Mars will provide details about the constituents of the lunar rocks and soil. Deposits of gold, platinum group metals, and rare earth metals are likely to be found. Especially promising in this regard are the numerous impact craters on the Moon. High concentrations of precious metals have been found in craters where asteroids impacted the Earth.
Riches are there to be had, and mining may well become a major industry on the Moon. -

SpaceX Is Planning To Launch a Falcon 9 For the Third Time (arstechnica.com)
According to the senior director of government sales for SpaceX, Lars Hoffman, the company is planning to launch a Falcon 9 first-stage booster for the third time. At the Wernher von Braun Memorial Symposium on Wednesday afternoon, Hoffman said: "We've launched Falcon 9 over 60 times. We've landed our first stage booster 30 times now. And relaunched 16 times. We're about to relaunch a booster for the third time. So we're turning this into routine access to space. High-reliability, higher-performance, lower-cost access to space; that opens it up to everybody." Ars Technica reports: The company has not officially confirmed its plans, but at present SpaceX intends to reuse a Falcon 9 rocket for the third time to launch a rideshare mission of dozens of small satellites for Spaceflight. This Spaceflight SSO-A mission currently has a launch date of November 19, according to a calendar maintained by Spaceflight Now. An earlier report in The Space Review previously indicated this mission may involve the third flight of a booster. -
Support For NASA Spending Depends On Perception of Size of Space Agency Budget
MarkWhittington writes "Alan Steinberg, a post doctorate fellow in political science at Sam Houston State University, conducted a study surrounding the vexing problem of how to motivate more people to support increased levels of funding for NASA. In an October 14, 2013 piece in The Space Review, Steinberg announced the results of a study conducted with a group of college students. Steinberg's approach was based on the findings of a study by Roger Launius conducted in the late 1990s that suggested that the American public believe that NASA spending takes up about 20 percent of the federal budget. It has in fact never exceeded four percent, which it enjoyed at the height of the Apollo program, and is currently about .5 percent. Steinberg was testing a notion advanced by Neil deGrasse Tyson that if people knew the true size of NASA's budget they would be more likely to support increasing it." -
NASA Faces Rough Road In 2013
MarkWhittington writes "With the National Research Council report that concluded that President Obama's plan for a mission to an asteroid has no support, either inside NASA or anywhere else, the space agency faces a decision point in 2013. The NRC suggested that the administration, Congress, NASA, and other stakeholders in space exploration come to a consensus behind a new goal. But the space agency's problems run deep, caused by a lack of direction, a lack of leadership, and a lack of funding." -
A Supercomputer On the Moon To Direct Deep Space Traffic
Hugh Pickens writes "NASA currently controls its deep space missions through a network of 13 giant antennas in California, Spain and Australia known as the Deep Space Network (DSN) but the network is obsolete and just not up to the job of transmitting the growing workload of extra-terrestrial data from deep space missions. That's why Ouliang Chang has proposed building a massive supercomputer in a deep dark crater on the side of the moon facing away from Earth and all of its electromagnetic chatter. Nuclear-powered, it would accept signals from space, store them, process them if needed and then relay the data back to Earth as time and bandwidth allows. The supercomputer would run in frigid regions near one of the moon's poles where cold temperatures would make cooling the supercomputer easier, and would communicate with spaceships and earth using a system of inflatable, steerable antennas that would hang suspended over moon craters, giving the Deep Space Network a second focal point away from earth. As well as boosting humanity's space-borne communication abilities, Chang's presentation at a space conference (PDF) in Pasadena, California also suggests that the moon-based dishes could work in unison with those on Earth to perform very-long-baseline interferometry, which allows multiple telescopes to be combined to emulate one huge telescope. Best of all the project has the potential to excite the imagination of future spacegoers and get men back on the moon." -
Is the OMB Trying To End Planetary Exploration?
EccentricAnomaly writes "Lou Friedman (former head of the Planetary Society) has written a provocative article over at Space Policy Review where he accuses the Obama administration of working on plans to gut the robotic Mars program in order to pay for NASA's exciting new rocket. This is after NASA already killed the Europa mission that was to have been the next outer planet mission after Cassini." -
NRO To Declassify Cold-War Spy-Sat Tech
Muad'Dave writes "The National Reconnaissance Office is set to reveal details of two of the cold war's most capable spy satellite programs on September 17th — the GAMBIT and HEXAGON projects, aka the keyhole KH-7, -8, and -9 satellites. These bus-sized sats provided critical imagery during the height of the cold war, and were likely the inspiration for the movie Ice Station Zebra. The article links midway down the first page provide a fascinating look into the world of real spy-vs-spy, cloak-and-dagger intelligence gathering." -
Why Shoot Down a Satellite? Analyzing an Analysis
A reader, name withheld by request, writes "Writing in the IEEE Spectrum, James Oberg analyzes whether there was, in fact a significant risk to humans from the satellite which the US military shot down on 21 February, purportedly 'to head off the possibility of its splashing a half ton of toxic hydrazine fuel somewhere on Earth.' Previous experts had 'scoffed' at the rationale put forth, pointing out that there was trivial possibility that any significant amount of toxic fuel would make it to the ground intact. Oberg's analysis, titled 'the inside story,' purports to debunk this, and claims that indeed it's possible, and even likely, that there could be a danger to the ground. Unfortunately, the analysis is full of flaws and lack of rigor — indeed, lacking any sort of numerical reasoning. It seems to be too much repeating official 'spin,' and could have used a hefty dose of skepticism — and could also use a little bit of actual analysis using numbers, rather than handwaving." Read on for the rest of an interesting analysis of a topic that suddenly seems more complex. The submitter continues: "Here's the first number that Oberg should have quoted: 32 Megajoules per kilogram. That's orbital energy, which is how much energy has to be removed by ablation or otherwise dissipated for the hydrazine tank to enter the atmosphere and hit the ground undamaged. For reference, TNT holds about 4.6 MJ/kg. Oberg quotes 'Hydrazine requires a tremendous amount of energy to go from solid to liquid.' This energy is known as the heat of fusion, and for hydrazine it is just a little under 400 kJ/kg. That's about 1% of the energy released by entry heating. Hardly a 'tremendous' amount of energy, compared to the entry energy that's nearly a hundred times greater.
Oberg goes on to quote 'There is a widespread notion that meteorites falling to Earth arrive red hot.' He is correct here. In fact, meteorites falling through the atmosphere typically explode, shattering into dozens or hundreds of pieces; something that occurs at the point when the dynamic pressure on the leading face exceeds the yield stress of the material. This occurs for meteoroids of all compositions, including nickle-iron meteorites that are far more robust than hydrazine tanks. If the atmospheric entry of meteorites is relevant, it hardly bolsters the case that a tank will enter intact (and if it's not relevent, why did Oberg bring it up?)
Furthermore, if you look at a typical nickle-iron meteorite, you'll see a surface pitted and mottled with holes ranging from the size of golf balls up to pits the size of baseballs. These are known as regmaglypts; they are the areas ablated away by the entry plasma. Even a single such ablation pit would, of course, destroy a hydrazine tank.
The second number Oberg should have quoted is a number called ballistic coefficient, the mass divided by the area of the tank. Basically, the smaller the ballistic coefficient, the less stressful the entry will be. Unfortunately, a full hydrazine tank has a very high ballistic coefficient. It is an empty tank, not a full one, that is likely to enter intact. Talking about empty film canisters, or even empty fuel tanks, making it intact through atmospheric entry is really about as relevant as talking about dropping a piece of paper on the floor.
The article contains a quote from Andrew Higgins, with a link to (purportedly) the research done that contains the quote. Unfortunately the link does not actually contain the quote used in the article; in fact, it seems to be mostly a discussion of a side issue. Let me emphasize this: Higgins did not say what he is quoted as saying in the place he was reported as saying it. This may merely be sloppy journalism — maybe he said it somewhere else — but I am again left with the question: if I can't even trust the simplest things he says that can be easily checked, why should I trust anything else?
In short, Oberg's article is poorly thought out, avoids even simple back-of-the-envelope calculations, and accepts uncritically information that should have been aggressively questioned. He concludes that a well-defined and thoroughly researched technological hazard assessment — of a kind that someday, for better or worse, will be needed again — has wound up buried in obscurity and obfuscation. This may be true, but no well defined nor thoroughly researched technological hazard assessment was anywhere in evidence. The analysis he gives in the article is buried in obscurity and obfuscation.

Where Are The Space Advocates?
QuantumG writes "Greg Zsidisin appeared on The Space Show today to ask Where Are The Space Advocates?. For the first time in decades Space is once again a political issue with all four major presidential candidates having something to say about space policy and yet nothing is being heard from space advocates. As we enter a new "Space Nexus" like we did after Apollo, now is a critical time to let your representatives know how you feel about space exploration, and yet no-one has anything to say." The show itself is a podcast if you want to give it a listen. Personally I'm hoping that this election puts space exploration back in the public consciousness- Apollo inspired a generation to learn math and science. I want my kid to be inspired by something bigger than that. And as some readers have noted- there are 3 candidates left (and really only two) so the submitter is probably high. -
Obama Would Redirect NASA Funding to Education
QuantumG writes "In a recent article on The Space Review, Greg Zsidisin reveals that Barack Obama plans to delay Project Constellation for at least five years, using the redirected funds to nationalize early-education for children under five years old to prepare them for the rigors of kindergarten and beyond, if he is elected president. It is feared that if this happens the Vision for Space Exploration will flounder and that may be the end of human spaceflight altogether." -
UK Reconsiders 1986 Decision To Ban Astronauts
An anonymous reader writes "The British space agency, BNSC, is reconsidering its 1986 decision to reject all human space missions. The decision has dominated British space policy ever since, leaving Britain out of many American and European space projects. The UK is the only nation in the G8 group of leading economies that does not have a human space flight program. But space enthusiast groups like the British Interplanetary Society are trying to persuade the British government to participate in both manned and unmanned space activities." -
How To Beat Congress's Ban Of Humans On Mars
An anonymous reader writes "Earlier this year, the House of Representatives passed a bill that would ban humans on Mars at NASA: "Provided, That none of the funds under this heading shall be used for any research, development, or demonstration activities related exclusively to the human exploration of Mars." The bill is held up in Congress and the anti-Mars language may be taken out. But in case the Mars ban becomes law, the Space Review has a handy guide on how NASA can beat the ban and continue its research and development without breaking the law." -
People Believe NASA Funded As Well As US Military
QuantumG writes "An essay on the Space Review site is reporting that a just-completed study indicates the average citizen has no idea how much funding NASA gets. Respondents generally estimated NASA's allocation of the national budget to be approximately 24% (it's actually closer to 0.58%) and the Department of Defense budget to be approximately 33% (it's actually closer to 21%). In other words, respondents believed NASA's budget approaches that of the Department of Defense, which receives almost 38 times more money. Once informed of the actual allocations, they were almost uniformly surprised. One of the more vocal participants exclaimed, 'No wonder we haven't gone anywhere!'" -
Can Space Nerds Get Along?
An anonymous reader writes "The Space Review asks whether space enthusiasts can ever get past the humans/robots and private/government flamewars. The article argues that space politics is a non-zero-sum game, and that space science, human spaceflight and private spaceflight can all co-exist. The debate between space and Earth is resolved in the same way: a non-zero-sum game that supports both Earth projects and space projects." -
Robert A. Heinlein's 100th Birthday
sasdrtx writes "Today is Robert A. Heinlein's 100th birthday. Regarded as one of the most influential hard Sci-Fi authors of the 20th century, it's definitely worth looking back at his influence on not only science fiction, but the space program, the english language, counter-culture, and political discourse. The Space Review has a piece entitled Ride the Lightning, which discusses Heinlein's history with the space program and (sometimes incorrect) assertions about the future of space flight. For a look at the official celebration, the Heinlein Centennial website has numerous resources available. The program for the event (pdf) makes it sound like they're having a great time in Kansas City." -
The Dozen Space Weapon Myths
Thanks to Disowned Sky for finding a good debunking piece on space based weapon systems. Slightly disheartening, because I really want to have solar energy satellites that are also lasers. The article does a good job of looking further afield at nations besides the United States efforts in this area. -
Fermi Paradox Predicting Humankind's Future?
An anonymous reader writes "The Fermi paradox says that if extraterrestrial civilizations exist, at least one of them should have colonized the entire galaxy by now. But since there is no evidence of this, humankind must be the only intelligent life in the galaxy. The Space Review has an article on how the Fermi paradox can be applied to human civilization. It says that, like the extraterrestrials, humans have three choices: colonize the galaxy, remain on Earth, or become extinct." -
The Skylab-Area 51 Incident
IZ Reloaded writes "The Space Review has an interesting story written by Dwayne Day about the 1974 incident when astronauts onboard Skylab took photos of a facility that did not exist in the US called Area 51. From The Space Review: What the memo indicates is that there was a difference between the way the civilian agencies of the US government and the military agencies looked at their roles. NASA had ties to the military, but it was clearly a civilian agency. And although the reasons why NASA officials felt that the photo should be released are unknown, the most likely explanation is that NASA officials did not feel that the civilian agency should conceal any of its activities. Many of NASA's relations with other organizations and foreign governments were based on the assumption that NASA did not engage in spying and did not conceal its activities." -
Lord British on Personal Spaceflight
FleaPlus writes "The Space Review has an interview with Richard Garriott (aka "Lord British"), best known as the creator of the genre-defining Ultima series of role playing games. In the interview he talks about his current work as the vice chairman of Space Adventures, and his thoughts on private-sector spaceflight in general. It includes an anecdote about how he funded the initial Russian studies which opened the door for Dennis Tito, Mark Shuttleworth, and Gregory Olsen's flights to the International Space Station, but was unable to go himself after the late-90s stock market bubble burst." -
t/Space Demonstrates New Air-Launch Method
FleaPlus writes "Last month t/Space, an organization with plans for constructing a simple, low-cost successor to the Space Shuttle, was mentioned on Slashdot. Recently t/Space used a portion of the concept study funds it had been awarded by NASA to also build and test actual hardware. They performed three weeks of drop tests of a 23%-scale model from a Scaled Composites Proteus carrier aircraft to demonstrate the feasibility of a new air launch method they had devised, dubbed 'Trapeze-Lanyard Air Drop.' The new method eliminates the need for wings on air-launched rockets, potentially leading to improved safety and cost-effectiveness. Last month at a space conference they also displayed a full-scale model of their vehicle. Unfortunately, with the recent selection of Boeing/Northrop-Grumman and Lockheed-Martin as the two competing teams for the contract to build the Shuttle's successor, t/Space's future path is somewhat uncertain." -
The Top Three Reasons for Humans in Space
An anonymous reader writes "Why humans in space? The Space Review has the top three reasons: 3. To work. 2. To live. 1. To survive. 'To work' means doing stuff in space: research, explore, visit, etc. 'To live' means to have humans/life beyond Earth in colonies/settlements. 'To survive' means that putting humans/life beyond Earth is a very Good Thing in case a very Bad Thing happens to humans/life on Earth." -
Competition to Build the Space Shuttle's Successor
Neil Halelamien writes "The competition for the prime contract to build the Crew Exploration Vehicle, the successor to the Space Shuttle, is ramping up. Currently, 11 different companies are creating preliminary designs for systems and vehicles which could be useful in implementing NASA's Vision for Space Exploration. By the end of the year, NASA will select two teams to independently develop and build a CEV design. The two teams will launch competing unmanned prototypes in 2008, at which point NASA will award a final winning contract. Aerospace giants Boeing and Northrop Grumman have formed one team. Another "all-star" team, announced a couple of days ago, is headed by Lockheed Martin. A third team in the running is underdog t/Space, a company with a free enterprise approach to space exploration, which includes notable figures from the commercial spaceflight arena, such as Burt Rutan and Gary Hudson. There is concern that a NASA budget boost to help pay for the exploration program could draw some opposition, as most other government programs are anticipating budget cuts." -

Imagining Titan
Neil Halelamien writes "Recently the Planetary Society released the winning entries of their Huygens Art Contest. The contest challenged contestants to create artwork depicting what they imagine the ESA's Huygens probe will find when it descends to Titan's surface. 435 people from 35 countries entered the contest, and several of the winning images look like they would make great desktop backgrounds. The Huygens encounter with Titan is due for January 14 (Friday), but it looks like there isn't any live coverage planned of this exciting event." -
Burt Rutan On Future Of SpaceShipOne (and Two)
Neil Halelamien writes "In a recent interview with the Desert Sun, Burt Rutan talks about the future of SpaceShipOne and SpaceShipTwo. The bad news is that SpaceShipOne will be retired straight to the Smithsonian Air and Space Museum, despite getting five different requests to fly suborbital payloads. The good news is that efforts are being focused on SpaceShipTwo, which will carry nine people, and fly higher and further downrange than SpaceShipOne. Virgin Galactic will purchase a fleet of five of these vehicles, which will start test flights in 2007. Virgin Galactic may end up competing with Jeff Bezos's Blue Origin, which is rumored to be developing a VTOL suborbital vehicle. Also interesting to watch will be Rutan's involvement with t/Space, one of the companies contracted by NASA to conduct concept studies for the Vision for Space Exploration." -
Private Spaceflight Law Passes Senate
Neil Halelamien writes "HR 5382, the commercial spaceflight bill which has been previously mentioned on Slashdot, has been passed by Congress at the last minute (almost literally). The bill had previously been stalled several times due to disagreements about how much the FAA should regulate crew and passenger safety. It's now headed to the White House to be signed into law. Under this legislation, the FAA's role until 2012 will be to protect the uninvolved public on the ground, and allow passengers to ride as long as they've been properly informed of the related dangers. Also, the FAA will be able to regulate certain aspects of the vehicles if they prove to be dangerous." -
The Space Elevator - Public or Private?
AtomicGoat writes "The Space Review reports that a Space Elevator may not get built without help from the U.S. Government, but the notion that 'the DoD can also provide a sense of fiscal discipline when dealing with large, expensive programs' sounds like an Onion story. Right now a small private company (Liftport), not NASA or the Air Force, is in the lead on revolutionary space travel." -
Soyuz To The Moon?
colonist writes "The Americans won the first race, but the Russians might beat them back to the moon. The reliable Soyuz, currently the only means of transport to the International Space Station, may send tourists on a voyage around the moon (gallery of illustrations). Constellation Services International's plans call for the Soyuz spacecraft to dock with a logistics module and an upper stage. The upper stage fires to send the Soyuz on a free-return circumlunar trajectory." -

Debunking the Trillion-Dollar Space Myth
jfoust writes "When the President and NASA announced the agency's new space initiative, including sending humans back to the Moon and on to Mars, many news reports claimed that the plan could cost as much as $1 trillion. According to this Space Review article, that trillion-dollar price tag is a myth: it was based on erroneous data and analysis, in large part by a single Associated Press reporter, and propagated by many other reporters too busy -- or too lazy -- to check on the facts. Could this kill the plan before it has a chance to start?" -
The Return of Apollo?
hpulley writes "Bell bottoms are back, the Stones are still touring and Time has a piece on how NASA's _new_ space vehicle may actually be the return of a very old friend, a highly modified and modernized version of the Apollo Space Capsule. Manned spacecraft might actually leave low earth orbit again! Initially they'd fly with Delta and Atlas but more powerful boosters could be developed. We could go to the Moon again, and perhaps to Mars but I'm getting ahead of myself. Does that mean the last 30 years of space flight have been for naught? Expensive steps backward?" -
The Business Case for Reusable Launch Vehicles
An anonymous reader writes "Remember the failures of "shuttle replacements" like VentureStar? A Space Review article argues that even if VentureStar succeeded technically, it and other proposed big RLVs would never have made it financially: they cost too much to develop and wouldn't have made it up through increased launches. What's the solution? The author says that suborbital RLVs, like what Carmack, Rutan, and the other X Prize contenders are working on, will create a business cycle that will eventually lead to orbital vehicles." -
Two Views On a China-US Space Race
An anonmous submitter writes "While there has been recent discussion about China and India engaging in a space race, most people are still focused on a potential race between China and the US in near future. The Space Review recently published a pair of essays on this topic: the first argues that China-US space race is both unlikely and undesirable, given the aftermath of the US-USSR space race thirty years ago. A followup article suggests that a China-US space race is vital, so long as it takes a more commercial, long-term approach than the US-USSR one. Food for thought..." -

Mars Failures: Bad luck or Bad Programs?
HobbySpacer writes "One European mission is on its way to Mars and two US landers will soon launch. They face tough odds for success. Of 34 Mars missions since the start of the space age, 20 have failed. This article looks at why Mars is so hard. It reports, for example, that a former manager on the Mars Pathfinder project believes that "Software is the number one problem". He says that since the mid-70s "software hasnâ(TM)t gone anywhere. There isnâ(TM)t a project that gets their software done."" Or maybe it has to do with being an incredible distance, on an inhumane climate. Either or. -
