Video: The Colossus telescope and the search for exoplanets with advanced tech civilizations

This SETI Institute talk combines two amazing developments of our day – the discovery of exoplanets and the development of giant telescopes. Jeff Kuhn of the Institute for Astronomy at the University of Hawaii gives an excellent presentation (suitable for a wide audience) about The Colossus Project: Designing an optical/IR instrument to detect life outside the solar system:

This talk describes an effort to detect life, and even conduct a planetary census, in our cosmic neighborhood. I’ll describe some results from the Colossus group, an interdisciplinary science and engineering team, working to show how telescopes much larger than the TMT or EELT could be built today by relaxing some of the astronomical requirements of current “world’s largest telescope” projects.

“The Ocean vs. Space” debate on line

There will be a debate today between

Alex Hall [Google Lunar X PRIZE] and Paul Bunje [Oceans at X PRIZE] at the Social Good Summit. Alex and Paul will be going head-to-head on “The Ocean vs. Space: Which is Really the Final Frontier?” debating the merits of investing in the exploration of their respective areas.

Copenhagen Suborbitals: Construction started of HEAT 1600 rocket booster

Copenhagen Suborbitals begins building the first of the big HEAT 1600 LE rocket vehicles:

Caption:

Copenhagen Suborbitals department of oversize rocket power :o) have started work on the HEAT 1600 rocket booster. With 260 kN thrust, it out powers a V2 missile, and with 12 tons of LOX / ethanol water mixture rocket fuel it can burn longer than than a V2.

Like the V2, and like all other large liquid propellant rockets, it rely on turbine pumps for pressurizing the propellants and delivering then at very high rate to the hungry combustion chamber at the back end. This makes the rockets structure very light, because it does not have to handle the full feed pressure of the engines. Other videos on this channel shows static tests of the turbine pumps, and the manufacture of the T-stoff or hydrogen peroxide that power them.

This must be the most powerful amateur build rocket ever devised. Yet, as the video shows we can build it, and we cn test it on the ground and ultimately launch it.

Therefore we must do it.

Like its little sister, the HEAT 2X also seen in the video – HEAT 1600 has a redundant flight termination system, and like the 2X, it will be launched at sea, where we have the very best range safety conditions that any rocket launch site can offer.

WE can build it. WE will do so and use it to launch a human into space. The “why” is best answered by others:

I will let the late president John F. Kennedy end this:

“Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it.

He said, “Because it is there.”

Well, space is there, and we’re going to climb it, and the moon and the planets are there, and new hopes for knowledge and peace are there. And, therefore, as we set sail we ask God’s blessing on the most hazardous and dangerous and greatest adventure on which man has ever embarked.

Thank you”

That´s quite simply why.

Video: Freeman Dyson joins a discussion of Dyson sphere searching

The video below is of a SETI Institute Google Hangout  devoted to a discussion of

the potential for the WISE telescope to detect extraterrestrial super-civilizations that acquired a large energy supply by building a mega-structure to harvest the energy of their star (“Dyson sphere“) or their entire galaxy.

The participants include

SETI Institute researchers Jill Tarter and Franck Marchis (host & moderator) will hangout with Jason Wright, professor of astronomy at Penn State, Matt Povich, professor of astronomy at Cal Poly Pomona and Freeman Dyson, theoretical physicist and mathematician at the Institute for Advance Study.
