Spacecoach: Toward a Deep Space Infrastructure

June 28, 2016

With manned missions to Mars in our thinking, both in government space agencies and the commercial sector, the challenge of providing adequate life support emerges as a key factor. We’re talking about a mission lasting about two years, as opposed to the relatively swift Apollo missions to the Moon (about two weeks). Discussing the matter […]

Stéphane Dumas (1970 – 2016)

June 17, 2016

The interstellar community is a small one, and reporting the loss of one of our number is not easy. SETI researcher Stéphane Dumas, who had been working with Claudio Maccone on the application of the Karhunen–Loève transform (KLT) for SETI observations, has died unexpectedly at his home in Quebec. I remember a wonderful conversation with […]

KIC 8462852: Where Are We After Eight Months?

May 10, 2016

The unusual star designated KIC 8462852, and now widely known as ‘Tabby’s Star,’ continues to be an enigma. As discussed in numerous articles in these pages, KIC 8462852 shows anomalous lightcurves that remain a mystery.

Beamed Sail Concepts Over Time

May 9, 2016

If you’ve been following the Breakthrough Starshot concept in these pages and elsewhere, you’ll know that it’s small at one end and big on the other. A beamed sail mission, it would use sails four meters to the side — quite small by reference to earlier beamed sail designs — driven by a massive phased […]

C/2014 S3: ‘Manx Object’ from the Oort Cloud

May 4, 2016

When you don’t have the technology to get to an interesting place like the Oort Cloud, it’s more than a little helpful when nature brings an Oort Cloud object to you. At least we think that the object known as C/2014 S3 (Pan-STARRS) has moved into the warmer regions of the Solar System from the […]

SETI: A New Kind of ‘Water Hole’

April 5, 2016

Some of you may recall an episode of Star Trek: The Next Generation in which the inhabitants of a planet called Aldea use a planetary defense system that includes a cloaking device. The episode, “When the Bough Breaks,” at one point shows the view from the Enterprise’s screens as the entire planet swims into view. […]

Thirteen to Centaurus

March 25, 2016

J. G. Ballard (1930-2009) emerged as one of the leading figures in 20th Century science fiction. His fascination with inner as opposed to ‘outer’ space infused his characters and landscapes with a touch of the surreal, taking the fiction of the space age into deeply psychological realms. Christopher Phoenix here looks at the question of […]

The Cereal Box

November 20, 2015

“No matter how these issues are ultimately resolved, Centauri Dreams opts for the notion that even the back of a cereal box may contain its share of mysteries.” I wrote that line in 2005, and if it sounds cryptic, read on to discover its origins, ably described by Christopher Phoenix. I first encountered Christopher in […]

July 7, 2015

While both Alan Stern and Glen Fountain admitted to having anxious moments over the weekend when New Horizons went silent, it became clear at yesterday’s news conference that those moments were short and quickly subsumed with ongoing duties. Stern is principal investigator for New Horizons, and the man most closely identified with making the mission […]
