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

NASA received last month more than two dozen proposals for the next round of its Discovery program of low-cost planetary science missions. Jason Callahan examines what we know about the various mission concepts submitted and the implications for NASA's overall planetary science program.

NASA rearms in its battle with mission skeptics
---
Last week NASA announced that it had selected an option for its Asteroid Redirect Mission that involves collecting a boulder from an asteroid and returning it to cislunar space. Jeff Foust reports on the reasons why NASA selected that option and why skeptics of ARM in general appear unlikely to be won over.

The Ides of Mars One
---
Mars One, the private venture planning one-way human missions to Mars, has suffered from setbacks and bad publicity recently. Dwayne Day describes how one aspect of the venture's plan, the development of a reality TV show about the mission, would have been difficult to pull off even without the recent problems.

India's indigenous satellite navigation system
---
On Saturday, India launched the fourth in a series of navigation satellites, bringing the nation closer to offering a regional navigation system independent of GPS. Ajey Lele discusses India's system and why the country, like a number of others, is deciding to develop its own satellite navigation system.

Several months after its theatrical release, the movie "Interstellar" will be available on DVD this week. With the risk of spoilers now subsided, Jeff Foust reviews a book that goes into detail about the science that formed the basis for the movie.

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


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.
