Last month NASA announced that the James Webb Space Telescope will require more money and more time before it will be ready to launch. Todd Neff notes that cost and schedule overruns are as old as the Space Age itself, a consequence of working on cutting-edge projects.
Orbital debris, satellite collisions, and ASAT tests have increased the awareness of the need of measures to preserve the safety of operations in Earth orbit. Jeff Foust reports on some potential and proposed measures the US and other countries can take in the near term to enhance space security.

The controversy over the “demotion” of Pluto from planet to dwarf planet is now over four years old, but new viewpoints on the subject continue to emerge. Jeff Foust reviews a new book by the astronomer whose discoveries of icy worlds in the outer solar system triggered the eventual reclassification of the former ninth planet.
A year ago commercial crew transportation was treated skeptically, at best, in the space community; now it’s a part of national policy with the support of companies large and small. Jeff Foust reports on how last week’s successful flight of SpaceX’s Dragon spacecraft may help secure the long-term future for commercial human spaceflight.
Some still question the utility of mounting human missions to near Earth asteroids. Lou Friedman discusses not only why such missions are important, but also why the timetable for them should be accelerated.

Jeff Foust examines how how this phenomenon, and especially the media coverage of it, could have a detrimental effect on actual spaceflight.
Future long-duration human spaceflight will require technologies that can sustain life while reusing and recycling as much as possible. Kit Martin argues that the same technologies can also be essential to sustaining life on Earth.

Stewart Money argues that the company’s most important innovation may not be its launch vehicles or spacecraft but a rocket engine that could be for space what another engine was for the automotive industry.

Mike Griffin spent nearly four years in charge of NASA building up an exploration architecture that the administration now wants to dismantle in favor of a new approach to human space exploration. Jeff Foust reports on what Griffin said about that new direction, and what is a “real” space program, in a speech last week.

As astronomy and physics have become more specialized, the requirements for performing research have become increasingly demanding. Jeff Foust reviews a book that is part review of our state of knowledge in these subjects, and part travelogue to the extreme locations on Earth where this research is performed.
The size of the challenges associated with human exploration beyond Earth orbit is likely beyond what any single space agency is willing to spend to carry out those missions. Andre Bormanis describes the types of partnerships that are critical to making such exploration possible.
NASA found itself embroiled in controversy earlier this month over a comment made by the agency’s administrator in a Middle Eastern television interview. Jeff Foust finds that the real message is not in the administrator’s ill-advised words but in the reaction to them.
As NASA and other space agencies seek evidence of past or present life on Mars and elsewhere, there’s the risk such exploration could contaminate those worlds. Linda Billings discusses the options to prevent such contamination, including even not exploring them at all.
More than 40 years after Apollo 11, it’s worth remembering that sites around the world helped make that mission, and the ones that preceded and followed it, a success. Jeff Foust reviews a book that examines the role of a little-known tracking station in Australia had on NASA’s early spaceflights and the impact it had on its host town.
Last week came word that Rocketplane has filed for bankruptcy, ending its long but ultimately unsuccessful effort to develop new suborbital and orbital launch vehicles. Jeff Foust examines how the company’s failure can be linked, at least in part, to a gap in financing models for NewSpace companies.
Weather is a frequent cause of launch delays and has been linked to a number of launch failures over the years. Wayne Eleazer examines two such launch failures and what they say about the launch decision process.
