Last week India launched its Polar Satellite Launch Vehicle (PSLV) for the first time since a failure in August. Ajey Lele explains that this mission did more than demonstrate that the problem that caused the failure had been corrected.
The Moon Treaty, not ratified by major spacefaring nations, has been criticized for its “common heritage of mankind” language. Vidvuds Beldavs argues that modest changes to the treaty could address those concerns while leaving in place a framework for enabling commercial extraction of resources from the Moon and asteroids.
A space policy directive signed last month directs NASA to return humans to the Moon, but how? Gerald Black argues that NASA can’t afford to do it in traditional ways, and needs to instead work in partnership with the private sector.
Spaceports are popping up around the United States and elsewhere, far outpacing the demand from commercial launch companies. Jeff Foust reviews a book that attempts to explain why that’s the case by visiting a number of existing and proposed launch sites.
President Trump signed a directive last month amending national space policy to call for a human return to the Moon. Chris Carberry and Rick Zucker argue that this need not be in conflict with plans for human missions to Mars, provided the administration is willing to back its policy with sufficient funding.
As commercial suborbital vehicles capable of carrying people prepare to enter service, those vehicles offers new opportunities for “ordinary” people to fly into space. John Putman cautions that such opportunities will require people to prepare not just physically but also psychologically.
As spacecraft become more advanced, and probe more distant parts of the solar system, communications becomes a weak link. Jeff Foust reports on how NASA is working on laser communications technologies for Earth science and planetary missions to dramatically increase data rates.
In the concluding part of her interview, Emily Carney talks with Jonathan Ward, co-author of a new book on the Columbia accident investigation, on the recovery effort and comparisons with other NASA human spaceflight accidents.

Next New Year’s Day, NASA’s New Horizons spacecraft will make a close flyby of a small object, or objects, in the Kuiper Belt. Jeff Foust previews the science, and the technical challenges, of the flyby.
A year ago, a classified US satellite reentered over the South Pacific without any advance warning or other notice by US government agencies. Charles Phillips discusses why, for safety’s sake, the government should provide a warning of such reentries without disclosing the satellite’s mission.
A new book due out this month chronicles the investigation into the Columbia shuttle accident 15 years ago. In the first of a two-part interview, Emily Carney talks with co-author Jonathan Ward about the development of the book and what he learned about the tragedy.
