I just downloaded a prepublication copy of a Decadal Survey in Astronomy and Astrophysics by the US National Research Council which lists LISA in third position among large space projects. It should be launched by 2025 in cooperation with ESA.

Yeah 2025 is like, well, when I'll pay off my credit card ( which is why we call it The Never Never DownUnda ). Machine Infinity. What were the first two ?

Cheers, Mike.

Quoting the Executive Summary:
In Space: (Large-scale, in priority order) Wide-Field Infrared Survey Telescope (WFIRST)—an
observatory designed to settle essential questions in both exoplanet and dark energy research, and
which will advance topics ranging from galaxy evolution to the study of objects within our own
galaxy. The Explorer Program—augmenting a program that delivers a high level of scientific
return on relatively moderate investment and that provides the capability to respond rapidly to
new scientific and technical breakthroughs. Laser Interferometer Space Antenna (LISA)—a lowfrequency
gravitational wave observatory that will open an entirely new window on the cosmos
by measuring ripples in space-time caused by many new sources, including nearby white dwarf
stars, and will probe the nature of black holes. International X-ray Observatory (IXO)—a
powerful X-ray telescope that will transform our understanding of hot gas associated with stars
and galaxies in all evolutionary stages. (Medium-scale, in rank order) New Worlds Technology
Development Program—a competed program to lay the technical and scientific foundation for a
future mission to study nearby Earth-like planets. Inflation Probe Technology Development
Program—a competed program designed to prepare for a potential next-decade cosmic
microwave-background mission to study the epoch of inflation.

Well I hope us old timers are

Well I hope us old timers are still around and involved with things like this in 2020-2025

These days I feel like I am the same age as Tycho or Johann

Imagine what they would think if they were with us today.

Probably they would say what a King of Spain said to an astronomer who described to him the Ptolemaic model with its cycles and epicycles, that if God had asked his advice he would have made it simpler. Now we no longer have cycles and epicycles but dark energy and dark matter. No great progress.

This book's authors (a who is who of American astronomy and astrophysics) never heard of BOINC and Einstein@home. Maybe the discovery of one and probably two pulsars by volunteers should open their eyes.

I can say with certainty that some of the authors DO know about BOINC and about Einstein@Home!

I was in Washington DC on Friday last week (August 13, 2010) and attended the press conference and release of the report at the National Academy of Sciences. I know some of the members of the committee and its various subcommittees who were also there. Several of them congratulated me on the E@H discovery, which had just been announced 21 hours earlier!

Cheers,
Bruce

Director, Einstein@Home

Yes I think they would ask us why we haven't gotton farther along than this with all the tools we have compared to what they had in 1604

But then Bohr,Fermi,Planck, and Tesla....among other could say the same thing I suppose.

According to a recent

According to a recent research made using a cluster of galaxies as a gravitational lens, the dark energy is confirmed. It should contain 72% of the Universe while another 24% is dark matter. What we see is only 4%. Not much.
