James Benford: Comments on METI

November 11, 2013

Pardon this extended introduction to Jim Benford’s response to Nick Nielsen’s Friday essay, but it comes at a serendipitous time. Jim’s recent online work has reminded me that we in the interstellar community need to work to see that as many resources as possible are made available online. In the absence of specialized bibliographies, useful […]

SETI, METI, and Existential Risk

November 8, 2013

To broadcast or not to broadcast? The debate over sending intentional signals to other stars continues to simmer even as various messages are sent, with no international policy in place to govern them. Writer Nick Nielsen looks at METI afresh today, placing it in the context of existential risk and pondering the implications of what […]

The Pros and Cons of METI

May 6, 2011

Tau Zero journalist Larry Klaes has been fascinated by SETI — and its offshoot METI (Messaging to Extraterrestrial Intelligence) — for a long time now. Here he steps back to look at METI in context, offering up an examination of the advantages of sending signals to the stars and the offsetting risks. We’ve looked at […]

Regarding METI and SETI Motives

September 22, 2009

by James Benford I first talked to Jim Benford back in 2003, discussing his work (wih brother Gregory) on microwave beam propulsion. He had already run experiments at the Jet Propulsion Laboratory demonstrating acceleration on a lightsail using these techniques, and was then hoping to run an experiment on The Planetary Society’s ill-fated Cosmos 1. […]

The Why of METI and SETI

September 18, 2009

by Larry Klaes About a decade ago while attending a SETI conference, I was listening to a researcher give a talk about detecting messages from other galaxies such as the giant elliptical galaxy Messier 87 and the immense Virgo galactic cluster it resides in. Since M87 is about 60 million light years from the Milky […]

METI: Learning from Efficient Beacons

October 30, 2008

If we want to consider how to pick up transmissions from a distant civilization, it pays to consider the most effective strategies for building interstellar beacons here on Earth. This is the method James, Gregory and Dominic Benford have used in twin papers on SETI/METI issues, papers that should be read in conjunction since the […]

The Prime Directive – A Real World Case

August 28, 2015

Trying to observe but not harm another civilization can be tricky business, as Michael Michaud explains in the article below. While Star Trek gave us a model for non-interference when new cultures are encountered, even its fictional world was rife with departures from its stated principles. We can see the problem in microcosm in ongoing […]

OSIRIS REx: Asteroid Sample Return

August 25, 2015

Just over a year from now, we’ll be anticipating the launch of the OSIRIS-REx mission, scheduled to rendezvous with the asteroid Bennu in 2018. This will be the first American mission to sample an asteroid, and it’s interesting to note that the materials scientists hope to return will constitute the largest sample from space since […]

The Scientific Imperative of Human Spaceflight

August 21, 2015

Interstellar distances seem to cry out for robotics and artificial intelligence. But as Nick Nielsen explains in the essay below, there is a compelling argument that our long-term goal should be human-crewed missions. We might ask whether the ‘overview effect’ that astronauts report from their experience of seeing the Earth from outside would have a […]
