The National Research Council’s human space exploration report released earlier this month did not look favorably on NASA’s Asteroid Redirect Mission (ARM) plans. Lou Friedman and Tom Jones argue that ARM, rather than being a dead end towards the long-term goal of Mars, is instead a key enabling mission.
In the past, many Western observers conflated China’s robotic lunar exploration plans with its human spaceflight plans. But as Dwayne Day explains, the two may be finally, if slowly, starting to truly come together.
While the concept of air launch seems compelling, such systems have failed to have much effect on the overall launch market. Jeff Foust reports on two different air launch ventures, one by DARPA and one funded by Paul Allen, attacking the air launch idea from two very different directions.
On Monday, an Indian PSLV rocket placed five satellites into orbit on a commercial mission. Ajey Lele examines what India needs to do to become more competitive in the global commercial launch market.

Both the National Research Council’s human space exploration and a separate internal NASA study lay out a path of missions and destinations for human spaceflight beyond Earth orbit. John Strickland argues that they fail, though, by following an Apollo-era paradigm of standalone missions.
In the conclusion of his two-part examination of planetary missions that failed to enter orbit as planned, Andrew LePage reviews four Mars missions by the US and former Soviet Union that failed to enter orbit as planned.
The release of the final report by National Research Council’s Committee on Human Spaceflight, evaluating the future of human space exploration, kickstarted a new round of debate about what that future should be. Dale Skran offers his assessment of the report, including where it falls short in assessing technical and commercial developments that could alter the report’s proposed pathways.
Two years ago, weak demand for commercial imagery and reduced government budgets drove consolidation among providers of such images; today, a number of startups are trying to get into the field. Jeff Foust reports on this new wave of interest, including one company’s recent acquisition by an Internet giant.
One of the most challenging aspects of planetary exploration, short of landing on another world, is entering orbit around it. In the first of a two-part article, Andrew LePage examines some of the missions that failed, at least on their first try, to achieve orbit around another solar system body.
Tensions with Russia have generated interest in Congress and elsewhere to develop a new large rocket engine to replace the Russian-built RD-180. Rick Boozer argues that such an engine might be available today, or very soon, had Congress not derailed NASA’s proposed launch vehicle development plans in 2010.
While Sally Ride was one of the most famous astronauts in American history, she was also a private person with secrets that didn’t emerge until after her death nearly two years ago. Jeff Foust reviews a new biography that artfully tells the public, private, and even secret lives of the first American woman in space.
Last week, the National Research Council’s Committee on Human Spaceflight issued its long-awaited report on the future of NASA’s human space exploration programs. Jeff Foust examines the report and the key issues it highlights, including whether the government and the public are willing to support a sustained long-term space exploration initiative.
Senator Richard Shelby has proposed that NASA require companies competing for the development of commercial crew systems to submit certified cost and pricing data. Sam Dinkin puts on his acquisition-economist hat to analyze the proposal.
A few months ago, the future looked dire for NASA’s SOFIA airborne observatory, as it faced a budget cut that would have mothballed it. As Jeff Foust reports, SOFIA’s fortunes are improving, but now another mission is facing the threat of termination.
With just over 18 months to go in the Google Lunar X PRIZE competition, a few teams are emerging as frontrunners with the best chance to capture the prize. Anthony Young looks at two of the teams that recently received support from NASA, as well as a third company not competing for the prize but also working on commercial lunar mission concepts.
Last week, SpaceX unveiled the design for its commercial crew vehicle, but it’s not the only contender for that NASA program. Jeff Foust reports on the latest progress made by Boeing, Sierra Nevada, and SpaceX, and the hard decisions facing these companies as NASA chooses some, but not all, of them to continue on the program.
The roles people play in space programs are often overlooked in comparison to technology, a problem exacerbated in classified programs. Dwayne Day discusses one exception to this rule in the form of a new book by, and interview of, someone who worked on early reconnaissance satellite programs.
Africa could benefit greatly from enhanced used of space, but lacks the expertise and resources to do so. Vid Beldavs proposes how a partnership between Africa and the European Union could benefit both, and even the world.

After more than a decade of lobbying by the space industry, the State Department published a final rule earlier this month moving most satellites and related items off the US Munitions List, and therefore no longer subject to ITAR. Jeff Foust notes that, while this is a major milestone, industry didn’t get everything they wanted, and there’s still some unfinished business to tend to.
One of the biggest uncertainties in space law and regulation today is determining who is responsible for collisions between spacecraft and debris. Timothy G. Nelson outlines the key legal issues associated with this topic.
NASA’s Space Launch System heavy-lift rocket and Orion spacecraft are two of NASA’s highest profile programs, and also two programs subject to significant criticism and debate. Jeff Foust reports on what the key companies involved in those two programs are doing to keep them on schedule in the near term as they also seek long-term stability.

There’s growing acceptance that NASA’s space exploration program should have the long-term goal of landing humans on Mars, perhaps in the mid-2030s. However, Jeff Foust reports there’s less information on exactly how NASA should go about achieving that goal, and whether any NASA strategy is affordable in the long run.
Too often debates about space exploration have focused on destinations, or whether robots or humans should be in the lead. John Strickland offers an integrated approach that maximizes the capabilities of both humans and robots to explore destinations throughout the solar system.
While the capabilities of commercial space ventures continue to grow, those efforts are increasingly being done in cooperation with governments. Anthony Young examines the rise of these public-private partnerships through several recent examples.
NASA first reached the Moon thanks to tremendous resources at its disposal during the Apollo era. Derek Webber argues that for NASA to explore in more fiscally constrained times, it must borrow a page from mountaineering and establish an infrastructure of “base camps” leading into the solar system.
The discovery of the first Earth-sized exoplanet in its star’s habitable zone has raised hopes that true Earth-like worlds may be common. Jeff Foust reviews a book where one scientist argues that Earth, in fact, may be a exceptionally rare planet.
The increase in tensions between the US and Russia would appear to provide NASA with a strong case for funding the agency’s commercial crew program and thus reducing reliance on Russia for accessing the International Space Station. Jeff Foust reports that while NASA has been making that case, some in Congress are not necessarily receptive to it.
While interest in small satellites is growing, the utility of such small spacecraft remains open to debate. Ethan W. Mattox discusses an effort by one element of the US military to test the feasibility of smallsats to provide communications support for special operations forces.
If reusable launch vehicles can dramatically lower launch prices, as some have argued about SpaceX’s efforts to develop a reusable Falcon 9, what markets does such a vehicle enable? Ajay P. Kothari examines the economics of RLVs regarding one well-known potential market, space tourism.

John Hickman interviews an author of a new novel that offers a different, and perhaps more credible, view of what they could be like.
Can a relatively ordinary shuttle mission, one without major achievements or problems, make for a compelling book? Jeff Foust reviews a book that profiles one such mission as seen from the vantage point of one of its crewmembers.
While a code of conduct for outer space activities has the backing of governments in the Europe and the US, there’s less support of the proposed code among Asian governments. Peter Garretson examines what issues are impeding the code in Asia and how a greater emphasis on space development could garner greater support for it there.
NASA made headlines last week when it announced it was suspending cooperation with Russia, with the notable and very large exception of International Space Station operations. Jeff Foust examines how much of an effect that ban will really have versus its symbolic effect in an era of tense US-Russian relations.
While some people believe that the next destination for humans beyond Earth orbit should be a return to the Moon, NASA is working instead on a human mission to a captured near Earth asteroid. Tom Chinick discusses how advancing capabilities in the commercial sector could allow human exploration and development of both.
Dennis Tito, the former space tourist now backing a proposal for a human Mars flyby mission, recently spoke out in favor of the Space Launch System (SLS) and Orion to carry out that and other missions. Rick Boozer argues that flaws with SLS/Orion could doom its use for Inspiration Mars and more.
NASA’s 2015 budget proposal included, for the first time, a small amount of funding to support studies of a proposed mission to Jupiter’s icy moon Europa.

Jeff Foust reports on what issues are currently of greater interest and importance to them.
The upcoming reusable Falcon 9 launch is generating some excitement. Sam Dinkin looks at the implications of projected lower launch costs for space settlement.
Today, we take for granted getting live high definition video from the International Space Station, but forty years ago, getting live TV of any kind from orbit involved technical and other problems. Jeff Foust reviews a book that examines the development and use fo live TV on Skylab, Apollo-Soyuz, and the beginning of the Space Shuttle program.
In May of last year, China launched what it said was a high-altitude sounding rocket for research purposes, but what many in the US believe was an ASAT test. In a comprehensive report, Brian Weeden examines the evidence that the launch was an ASAT test, the historical record of such tests by other countries, and its implications for space security.
After nearly two decades of development, the SOFIA airborne observatory is about to formally enter its operational phase. However, Jeff Foust reports, the future of SOFIA is in jeopardy after NASA proposed cutting funding for it in its 2015 budget proposal, a move that could significant scientific and even geopolitical implications.

Many in the space community are growing impatient with Virgin Galactic as development of its SpaceShipTwo program encounters extended delays. Jeff Foust reviews a book about Virgin’s founder, Sir Richard Branson, that offers a sharply critical look at the company, but one that may also be factually flawed.
The US Air Force announced recently a “bulk buy” of EELV rockets from United Launch Alliance that it claims will save the government billions of dollars. Stewart Money argues that such savings may prove elusive and that the government’s EELV strategy should be reconsidered given the rise of new entrants like SpaceX.
For a time last week, Western media widely reported that China’s Yutu, or “Jade Rabbit,” lunar rover had died, only to have officials sources state that the rover was alive, if not completely well. Jeff Foust examines both the faults in the erroneous media coverage and the lack of official information about the mission.
He may have flown only once in space, but Apollo astronaut Walt Cunningham remains one of the better-known figures of that era and beyond. Shane Hannon interviews Cunningham about both Apollo 7 and more contemporary topics, including his thoughts on the future of human space exploration.
There have been, over the years, many science fiction stories of human Mars mission gone awry. Jeff Foust reviews a new book that offers a different but compelling take on that, a “hard” science fiction story of one astronaut’s quest to survive after being left behind on Mars.
Winning broad support for human space exploration efforts, be they to the Moon, asteroids, or Mars, has long been challenging. Matt Greenhouse argues its time for human spaceflight at NASA to adopt the approach for choosing missions that has generated considerable success for the agency’s science programs.
As companies develop commercial spacecraft to carry private citizens and NASA astronauts on suborbital and orbital flights, some worry that safety could be sacrificed to lower costs.

This week is a somber one for many in the space community, given the confluence of the Apollo 1, Challenger, and Columbia anniversaries. Ken Murphy describes how the rest the the year offers more upbeat opportunities to commemorate and celebrate spaceflight.
Two and a half years after the end of the last Space Shuttle mission, the program is firmly in NASA’s past, even if it still casts a shadow on the agency today. Jeff Foust reviews a book that examines the history of the Shuttle program post-Challenger, with interviews of many of the astronauts who flew on those missions.
Many people agree that low-cost space access is important to the future of spaceflight, but there’s no consensus about how to achieve it. In the first of a two-part excerpt from a new book, Charles Miller looks back to the early history of aviation for lessons that can be applied to spaceflight.
As many in the space community celebrated the final 2014 NASA budget last week, they overlooked a very different milestone: the tenth anniversary of the presidential speech announcing the Vision for Space Exploration. Jeff Foust looks back on than anniversary and how some are carrying on a goal that survived the Vision’s demise: sending humans to Mars.
To outsiders, those involved with launch campaigns can appeared obsessed with details to the point of paranoia. Wayne Eleazer discusses how this is a normal and even healthy attitude to take, given the hard lessons companies have learned over the years.
NASA officials and others frequently emphasize the priority safety has in human spaceflight. Jeff Foust reviews a book that makes the argument that safety is, in fact, being overemphasized at the expense of making significant progress in space exploration.
Last week, the White House and NASA announced that the US wants to operate the International Space Station to at least 2024, four years later than previously planned. Jeff Foust reports on the reaction to those plans both in the US and among the international partners, who have yet to agree to such an extension.
A recent op-ed criticized space tourism for being environmentally unfriendly, with a carbon footprint per person much larger than for commercial aviation. Joe Mascaro makes the case that environmentalists should actually embrace the growing opportunities of commercial spaceflight.
Much of the criticism regarding the Space Launch System has been about its large size and cost. John Strickland argues that the true root of the SLS’s costs is not that it’s large, but that it is expendable, and thus unaffordable.
As more nations and companies show an interest in going to the Moon and making use of its resources, a regime to effectively govern access to those resources may be needed. Vid Beldavs discusses a proposal to study those resources and develop technologies to access them within the framework of an existing treaty.
As heads of space agencies meet in Washington this week for a space exploration conference, some in the US call for a change in direction in NASA’s human spaceflight program. Jeff Foust reports on several views of what NASA should be doing, as proposed in a new book.
