Welcome to this week's issue of The Space Review:



For commercial cargo, ideas old and new
---
At least five companies have said they have submitted proposals to NASA for commercial cargo contracts. Jeff Foust describes the proposals made by two companies seeking to enter this market, one repurposing a crewed vehicle concept and the other offering a novel approach that could be used beyond Earth orbit as well.

The return of the satellite constellations
---
In the 1990s, a number of ventures tried to develop constellations of dozens or hundreds of communications satellites; they either ended up in bankruptcy reorganization or failed outright. Yet, Jeff Foust reports, there are today a number of firms, with significant financial support, trying even more ambitious systems.

Review: After Apollo
---
Many people still consider John F. Kennedy as the president with the great influence on the American space program. Jeff Foust reviews a book that examines the historical record of another president who, in the long run, may have had a more significant effect on NASA's human spaceflight program.

If you missed it, here's what we published in our previous issue:


Starfleet was closer than you think
---
More than half a century ago, Project Orion offered the potential to open up the solar system with nuclear propulsion technologies, only to be shelved. Brent Ziarnick and Peter Garretson discuss, based on recently declassified memos, that the Air Force was closer than previously believed in deciding to fund work on Orion.

The core of NASA's mission
---
A hearing last week by a Senate committee about NASA's propposed budget became a discussion on what NASA's "core mission" should be. Jeff Foust reports this is not the first time, and likely not the last, the issue will be debated.

Failure to launch: the technical, ethical, and legal case against Mars One
---
Mars One has garnered publicity in recent weeks with the selection of 100 candidates to be members of their first one-way Mars crew in the mid-2020s. Michael Listner and Christopher Newman argue that Mars One has yet to deal with a number of major technical and other challenges that makes their venture unlikely to succeed.

Review: Asteroid Mining 101
---
The last few years have seen companies attempt to turn asteroid mining from a topic of science fiction to a profitable business. Jeff Foust reviews a book that examines the science and technical issues associated with the field.
