March 2008:One size may not fit allAs Virgin Galactic and Scaled Composites continue the development of SpaceShipTwo, other companies are making headway in the commercial suborbital spaceflight market. Jeff Foust reports on recent developments by XCOR Aerospace and other companies, and how the diversity of technical approaches may be received by the market. The next battlestarNASA’s science program, already constrained by tight budgets, will soon have to take on the challenge of both a flagship outer planets mission and a Mars sample return mission. Taylor Dinerman questions whether the agency can handle two such major missions at the same time. Killer birdieKE-ASAT was a long-running, but little-known, effort to develop an antisatellite weapon. Dwayne Day reports on a mockup recently found that appears to be associated with the project. Assessing the practicality of scramjet-powered, single-stage aerospaceplanesTo many the ideal low-cost, reusable launch vehicle is a scramjet-powered spaceplane. Mike Snead examines the technical issues and challenges associated with developing such vehicles. Review: Beyond UFOsTo many, life on other worlds means aliens and flying saucers. Jeff Foust reviews a book that tries to move beyond those perceptions to provide a solid scientific review of astrobiology. Too few or too many?Last weekend’s failure of a Proton rocket is the latest complication for the commercial launch industry, which has seen manifests fill up and customers complain about schedules and costs. Jeff Foust reports on the differing points of view about whether there are enough—or even too many—launch services providers. Messy battlefieldsIf there is ultimately warfare in space, it will likely create a large amount of debris. Taylor Dinerman writes that countries that depend on space assets, like the US, need to prepare for this possibility by making their spacecraft harder to intercept and harder to damage. Planting a flag is only the beginningSo much attention has been given to implementing the Vision for Space Exploration that there has been little thought as to what will follow it. Jeff Brooks argues that making the case for the economic benefit of the Moon, Mars, and beyond is essential. Letters: wrapping up the USA 193 debateIn the conclusion of their debate about the intercept of the USA 193 satellite last month, Yousaf Butt and Andrew Higgins make their final points on the physics of hydrazine and satellite reentry models. ITAR’s failureCurrent US export control regulations make it difficult for companies, particularly smaller ones, to compete on the international market. Taylor Dinerman makes the case for some degree of reform that will ease the regulatory burden on these companies. The end of the golden age of Mars exploration?While NASA is celebrating the continued successes of its current Mars missions, the future of its robotic Mars exploration efforts is uncertain. Jeff Foust reports on concerns some scientists are expressing about a possible break in the steady stream of landers and orbiters going to the Red Planet. British space policy on life, the universe, and everythingThe UK is reconsidering its long-standing opposition to human spaceflight. Michael Huang examines the debate the opposition to any change in British policy. Letter: hydrazine reduxYousaf Butt continues the debate on the technical merits of intercepting the USA 193 satellite by reexamining just how likely the hydrazine in the spacecraft’s propellant tank would have survived reentry. Review: Human Missions to MarsA long-term goal of human spaceflight is to send missions to Mars, but that is an approach fraught with technical challenges. Anthony Young reviews a book that examines in detail the issues associated with human Mars exploration. Will we burn in heaven like we do down here?How real is the threat of an arms race in space, and how effective would measures like treaties be in preventing one? Dwayne Day recounts a recent debate on the subject. Investment in entrepreneurial innovation: why cooperate?In the highly competitive world of business, why should companies work together to help develop a new industry? Paul Eckert explains why various companies and organizations are doing just that to help promote the entrepreneurial space sector. Hoping for a reality tomorrowLast week’s Goddard Memorial Symposium provided an opportunity not just to look back at the first 50 years of the Space Age, but to also look ahead to the next 50. Jeff Foust reports on what the administrator of NASA and the president’s science advisor hope today will be become the reality of tomorrow. Space weapons agreements, treaties, and politicsRecent events have renewed the debate on the effectiveness of a treaty banning space weapons. Taylor Dinerman discusses the arguments made in opposition to such a treaty made by a senior State Department official last week. Letter: The physics of reentering fuel tanksWhat would have happened to USA 193’s fuel tank if the spacecraft has been allowed to reenter naturally? Andrew Higgins argues that, contrary to other claims, the tank would have likely survived reentry intact. Review: The Mystery of the Missing AntimatterIf antimatter is the mirror image of matter, why is the universe dominated by matter? Jeff Foust reviews a book that takes readers on a journey through modern physics to try and answer that question. China and the US: space race or miscommunication?The rise of China as a major space power is seen by some in the US as a threat to American prestige, if not national security. Jeff Foust reports that, for some experts, the real concern is the misperceptions that exist in the two countries about each other’s projects and intents. ATV, Cygnus, and DragonIn less than a week ESA will launch its first ATV cargo spacecraft to the ISS. Taylor Dinerman compares and contrasts the capabilities and future potential of that vehicle with two similar vehicles being commercially developed in the US. Sense, nonsense, and pretense about the destruction of USA 193The flurry of media accounts about the intercept of the deorbiting satellite last month featured their share of inaccuracies and misinterpretations of the event. James Oberg attempts to debunk some of the biggest myths and misunderstandings associated with the satellite’s destruction. Letter: responding to satellite shootdownYousaf Butt responds to a previous essay in The Space Review about last month’s satellite intercept, arguing that the US should release the analysis it performed on the hazards of the satellite’s reentry to justify the effort and expense involved with the intercept. Blitzing Capitol HillLast month dozens of space activists came to Washington to lobby members of Congress to support the NASA budget and related initiatives. Alex Kirk offers an overview of the event and a discussion of the importance of targeted, specific pitches for support. Raketen in BerlinGermany’s war history has meant that its museums feature far less aerospace exhibits than their counterparts in the US and other countries. Dwayne Day provides a pictorial review of one example of this in Berlin. February 2008:Hale and farewellLate last week NASA announced that shuttle program manager Wayne Hale was being reassigned to a new position within the space agency. Dwayne Day looks back at Hale’s role in the post-Columbia shuttle program and what implications his departure could have. Satellite shootdown overcomes bureaucracyThe biggest challenge in last week’s intercept of a spy satellite by a missile may not have been the technology. Instead, Taylor Dinerman argues, it may have been the bureaucracy that had to be overcome within the Defense Department to make the attempt possible. Seven generations: a re-evaluation of the Paine ReportNASA’s exploration program faces an uncertain future given the upcoming change in administrations. Alex Howerton looks back to a report completed over 20 years ago for guidance on how the nation should continue its space efforts. John Glenn and the Flying BananaFrank Piasecki may not be familiar to space enthusiasts, but he played a cameo role in the early years of the Space Age. Dwayne Day recounts how Piasecki’s unusual helicopter ferried the first American in space. Review: Twilight WarLast week’s intercept of a failed spy satellite by a US missile has been seen by some as evidence of American plans for space weaponization.

An interview with Richard GarriottRichard Garriott, a famous computer game designer, will be the next commercial passenger to visit the International Space Station this fall. Sam Dinkin interviews Garriott to find out what training has been like so far and what his plans are for the flight and beyond. Spysat down!The Pentagon announced last week it would intercept a dead spysat in a decaying orbit with a missile. Dwayne Day recounts what happened when another reconnaissance satellite fell from the sky and embarrassed the US. Screening and training for commercial human spaceflightAs the commercial human spaceflight industry emerges, companies will be flying people who do not meet the same rigorous medical guidelines of government astronauts. Jeff Foust reports on the screening and training issues companies in the field are considering as they seek to maintain customer safety while maximizing the number of people who can fly. Space myths 2Conventional wisdom in the space field includes a preference for simple rockets and the development of airplane-like RLVs. Wayne Eleazer calls those concepts into question.

Dwayne Day examines what we know—and have yet to find out—about the Manned Orbiting Laboratory project. India and the US: partners or rivals in space?India’s space program is evolving from one focused strictly on practical benefits to one that supports exploration and, perhaps, human spaceflight. Jeff Foust reports on Indian officials see the future of their space program, and what effect that will have on relations with the US. Space policy optimists and othersThe next president will have the opportunity to continue, alter, or terminate NASA’s current exploration effort. Taylor Dinerman describes discussion on this topic at a recent forum and its implications for human spaceflight in general. Defending ConstellationDespite being in place for over two years now, NASA’s exploration architecture continues to attract criticism from those who have technical and financial concerns. Jeff Foust reports on how NASA administrator Mike Griffin responded to that criticism with a detailed defense of the effort. Fire and graceLast week, as part of the ceremonies marking the 50th anniversary of Explorer 1, the US Space and Rocket Center opened its new Davidson Center, housing a Saturn 5 rocket. Dwayne Day reviews the new facility in a photo essay. What to tell the next president about realizing America’s potential in spaceLater this week space community leaders will meet in Washington for a two-day forum on space policy issues facing the next president. Mike Snead explains how this is an opportunity to discuss what changes are needed to make the US a “true” spacefaring nation. Not-so-rare Earth?Several years ago, the authors of the book Rare Earth argued that “complex” life in the universe was likely very uncommon. Taylor Dinerman argues that recent discoveries, particularly of extrasolar planets, put that hypothesis in question. If we build it, will they come?Will new markets drive the demand for low-cost launch, or will the development of low-cost launch vehicles stimulate the development of new markets? Eric Hedman examines this chicken-and-egg issue within the context of space-based solar power. January 2008:Call their bluffJust over a year ago China shook up the space security field by testing an anti-satellite weapon. Mike Moore looks at the impact this test had on military space policy and argues that the US should use the test to see if China is sincere about desiring a treaty banning space weapons. Some ORS for ORSOne of the challenges facing Operationally Responsive Space is how low-cost rapidly-launched small satellites can serve the needs of military forces not otherwise served by existing satellites or UAVs. Dwayne Day discusses whether and how ORS can find a niche among the various alternatives.

Taylor Dinerman examines how the company is trying to balance space commercialization with environmental protection. Canada’s space program in crisisEarlier this month Canadian company MDA announced it was selling its space business to a US firm, ATK, shocking many Canadians. Chris Gainor laments the implications of this sale for Canada’s modest space efforts. Monster chopperThe 1960s were full of grandiose visions of spaceflight, some more grandiose than others. Dwayne Day describes one such proposal from that era, for a gigantic helicopter that would have been used to recover rocket stages. Review: America’s Deep Space PioneerFifty years ago this week, the US entered the Space Age with the launch of its first satellite. Jeff Foust reviews a new biography of William Pickering, one of the key people behind Explorer 1 and the early history of spacecraft missions to explore the solar system. The dark side of space disaster theoriesA new book by a noted space conspiracist argues that a string of NASA Mars mission failures in the 1990s were coverups to hide their secret activities. James Oberg debunks those claims by explaining how the authors misunderstood, inadvertently or deliberately, the technical causes for those failures. The China gambitA recent op-ed suggested that the United States allow China to join the International Space Station project for both practical and political purposes. Dwayne Day examines the benefits and issues of such a proposal. Is a secret a lie if it just isn’t true?Chinese rocket engineer Tsien Hsue-shen has attracted new attention and scrutiny after being given an award by a major magazine. Dwayne Day follows up on an essay last week about Tsien with new information about what the US government claimed to know about him and his alleged espionage. Is space exploration worth the cost?Recently the New York Times blog Freakonomics surveyed a number of experts to ask then whether human spaceflight was worth the cost, and why. One of those featured, David Livingston, offers the full version of his answer to that question.

The Vision’s critical yearMonday marks the fourth anniversary of President Bush’s speech announcing the Vision for Space Exploration. Jeff Foust examines the political, fiscal, and other issues that make 2008 a critical year for the future of the exploration program. A dragon in winterIn a surprise move, Aviation Week selected Chinese engineer Tsien Hsue-shen as its person of the year for 2007, despite playing little direct role in the events that transpired last year. Dwayne Day reviews what’s known about Tsien, as well as some of the false allegations that have been published about him. Is the shuttle delay good news for the AMS?Continuing delays with the launch of the next shuttle missions are raising new questions about NASA’s ability to retire the shuttle fleet in 2010. Taylor Dinerman argues that this may give supporters of a scientific experiment denied a ride on the shuttle new hope for getting into space. Secrets and signsA long-running challenge for many observers has been to identify the missions of classified US launches. Dwayne Day and Roger Guillemette describe how a surprising amount of information about those missions can be found from an unlikely source: their patches.
