Jeff Foust describes the company’s launch concept and the issues that have generated skepticism in some quarters.
Missing from the debate about the future of NASA’s human spaceflight efforts is one long-term question: what comes after the ISS? Roger Handberg argues that the failure to contemplate that question now could eventually mean ceding leadership in space station efforts to the Chinese.
NASA appeared set to press ahead with more conventional contracts for the next phase of its commercial crew program, but last week the agency abruptly changed course and said it would go back to Space Act Agreements instead. Jeff Foust reports on the reasons for the change and the reactions from industry and government.
While women are commonplace in NASA’s astronaut corps today, commanding missions and holding management positions, it took considerable effort for women to become astronauts. Jeff Foust reviews a book that discusses the political, cultural, and technical issues associated with that integration.
The US government is grappling with both the growing costs of existing launch vehicles and the emergence of new, if relatively untested, competitors. Stewart Money argues that the future of reliable, cost-effective space access depends on enhanced competition among launch providers.

John Strickland argues that the SLS, as currently conceived, will be too expensive to support the exploration missions and other applications envisioned for it.
Space-based solar power is a concept that has strong support from a small number of space advocates, but little attention or funding from broader audiences. Jeff Foust reports on a new study that offers optimism for the future of space solar power even as the political landscape for supporting it becomes even more challenging.
A European Union proposal for a “Code of Conduct” for space activities has run into opposition from some countries, including India. Michael Listner discusses what Indian officials find objectionable in the code and the options for handing those concerns.

This week Russia will launch Phobos-Grunt, a mission to travel to Mars and return a sample of the Martian moon Phobos. Lou Friedman describes the mission and an unusual experiment from The Planetary Society that is onboard the spacecraft.
Phobos-Grunt is a very ambitious mission for any space power, let alone for a country that hasn’t launched a Mars mission in 15 years. Dwayne Day writes that it may be too ambitious a mission, but if successful could have a major payoff for planetary exploration.
Phobos-Grunt is the latest in a long line of Russian/Soviet Mars missions, most of which failed. Doug Messier examines the history of that program and whether this mission can break from that history.
In the next few weeks Congress is expected to wrap up work on NASA’s 2012 budget, including deciding how much money to allocate to the agency’s commercial crew program. Alan Stern and Frank DiBello argue that NASA, Congress, and the White House should work together to get that program moving as fast as possible.
Members of Congress introduced a bill last week to provide some potential export control relief for the satellite industry, while the administration continues work on its own reform efforts. Jeff Foust reports on the progress being made on both fronts, and the prospects in this latest round of the long-running struggle for export control reform.
NASA has proposed guidelines to prevent future lunar vehicles from damaging or contaminating artifacts left behind by the Apollo missions. Matthew Kleiman describes how those voluntary guidelines can be supported by international law.

While NASA begins development of the heavy-lift Space Launch System (SLS) rocket, some have proposed propellant depots as an alternative architecture. Andrew Gasser argues that depots, despite the criticisms of some, offer a feasible and less expensive approach to human space exploration.
The Moon Treaty is widely regarded as a failed treaty since the biggest spacefaring nations, including the United States, have not signed on to it. Michael Listner warns, though, that elements of the treaty could make their way into international law even if the US doesn’t sign or ratify the treaty.
With the shuttle now retired, books recounting the history of the program are making their way onto bookstore shelves. Jeff Foust reviews one such book that includes stunning imagery from various shuttle missions, but has one surprising omission.

Cost overruns with the James Webb Space Telescope will require NASA to take money from other programs, perhaps including human spaceflight, to cover its costs. Michael Kaplan explains how the two programs can instead be synergistic.
While most of the recent attention on new launch systems has focused on NASA’s Space Launch System and SpaceX’s plans for a reusable Falcon 9, other vehicles are reshaping the industry landscape as well. Jeff Foust reports on some recent developments by several vehicles, and renewed concerns about overcapacity in the market.
NASA’s announced design of the Space Launch System rocket enables the space agency to pursue the goal set by the president of a human mission to an asteroid by 2025. Anthony Young wonders, though, if such a mission is compelling enough to hold interest over the years leading up to it.

NASA’s exploration of the outer solar system has been enabled by the use of plutonium-powered RTGs that generate electricity where solar panels would be ineffective. Jeff Foust reports how declining stocks of a plutonium isotope, and policy battles regarding how to fund its production, jeopardize future planetary missions.
The recent movie Apollo 18 has been panned by many critics, including in the pages of this publication. Dwayne Day argues that this movie does has some redeeming qualities, though, that should not be overlooked.

The Space Shuttle’s legacy has been widely debated as the program reaches its end: despite all its accomplishments, it failed to achieve its original goals of cost reduction. Andre Bormanis argues that the shuttle should best be remembered for taking a step on the path towards better and less expensive space access.
The end of the Space Shuttle program marks a profound change for NASA, in more ways than one. Roger Handberg warns that in the post-shuttle era the political environment for NASA may become more difficult and partisan.
