Better than Paris: space solar power

Mon, 19 Jun 2017 10:59:00 GMT

However, in the first of a two-part paper, Robert Zubrin argues that other formats may be more effective, with implications both for SETI and astrobiology in general.



Sunlight and shadow: putting people on Mars

Mon, 19 Jun 2017 10:57:00 GMT

The decision to send humans to the Moon in the 1960s was in a very different geopolitical environment from the one that exists today when planning human missions to Mars. Mack A. Bradley discusses how to make human Mars exploration relevant when old arguments no longer apply.



Review: Apollo 8

Mon, 19 Jun 2017 10:56:00 GMT

Schiaparelli did more things right than it did wrong

Tue, 30 May 2017 10:59:00 GMT

Jeff Foust reviews a book that encompasses that history, but one that focuses on the distant past than more recent accomplishments.



A counterspace awakening? (part 1)

Mon, 22 May 2017 11:00:00 GMT

Jeff Foust reviews a book and a documentary that try to place NASA's efforts in a broader perspective.



No rush for Mars

Mon, 15 May 2017 11:00:00 GMT

A few weeks after President Trump suggested that NASA needed to accelerate plans to send humans to Mars, agency leadership said they've received no direction to do so from the White House. Jeff Foust reports this is a sign that neither the government nor most companies are in a particular hurry to send humans to Mars.



Buzz Aldrin will not stop talking

Mon, 15 May 2017 10:59:00 GMT

Stranger danger: Extraterrestrial first contact as a political problem

Mon, 15 May 2017 10:58:00 GMT

Loss of faith: Gordon Cooper's post-NASA stories

Mon, 01 May 2017 10:57:00 GMT

Mars ain't the kind of place to raise your kids

Mon, 24 Apr 2017 10:59:00 GMT

Which comes first for a new National Space Council: organization or vision?

Mon, 17 Apr 2017 10:57:00 GMT

Review: Mission Control

Mon, 17 Apr 2017 10:56:00 GMT

Time for common sense with the satellite catalog

Mon, 10 Apr 2017 11:00:00 GMT

The small launch industry is about to be Amazoned

Mon, 10 Apr 2017 10:58:00 GMT

The threat of asteroid impacts is real, but often overhyped. Jeff Foust reviews a book that offers a thoughtful examination of asteroid impact risks and how astronomers are keeping tabs on the skies.



Now to make it pay off

Mon, 03 Apr 2017 11:00:00 GMT

SpaceX achieved a major milestone last week with it successfully launched a satellite using a Falcon 9 first stage that had previously flown. Jeff Foust discusses how the question is now not whether such reusability is technically feasible, but rather if it can make economic sense.



Has the space launch industry been too focused in the last 70 years?

Mon, 03 Apr 2017 10:59:00 GMT

How space settlement can challenge consumerism

Mon, 27 Mar 2017 10:57:00 GMT

Human flight around the Moon: a worthy goal, but using the wrong vehicles

Mon, 27 Feb 2017 10:58:00 GMT

If sending people back to the Moon is a good idea, should it be done with SLS and Orion? Gerald Black argues that it makes more sense to send humans back to the Moon using commercial vehicles arguably further along in their development.



A radically easier path to space settlement

Mon, 27 Feb 2017 10:57:00 GMT
