Updates from Past Recipients of the Shoemaker NEO Grants

Posted by Bruce Betts on 2005/08/17 12:00 CDT

Update as of July 28, 2005 Following last year's Potentially Hazardous Asteroid and a few other non-main-belt discoveries, I looked into what improvements I could make to more efficiently image the sky. The major advance involved the design of a 3-lens corrector comprising 2 stock lenses and a custom lens I made myself.

The Story of Cosmos 1 is Not Over: A Personal Report

Posted by Louis D. Friedman on 2005/06/25 12:00 CDT

The word failure is sticking in my craw. Certainly, we failed to achieve the objective of Cosmos 1: we did not achieve solar-sail flight. But I don’t think, with all we have done, that I can call Cosmos 1 a failure.

Launching Cosmos 1 on a Soviet ICBM

Posted by Louis D. Friedman on 2005/05/25 12:00 CDT

The biggest reason that NASA—as well as other western space agencies—has not attempted a solar sail flight is that the cost of launching even a small spacecraft is so high that they are unwilling to carry out a mission with very modest goals.

Pulses, Triplets, and Gaussians: Rescoring the Reobservations

Posted by Amir Alexander on 2004/05/17 12:00 CDT

It has been more than a year since the SETI@home crew spent a hectic week at Arecibo, pointing the giant radio telescope at some of SETI's most promising targets. Much of the data collected during the reobservations has since been repackaged as work units, and sent out to users around the world for analysis.

Updates from Past Recipients of the Shoemaker NEO Grants

Posted by Bruce Betts on 2004/04/16 12:00 CDT

Update as of March 24, 2004 2003 was a good year with 50,779 asteroid astrometric observations submitted, including known NEOs and the discovery of a new Aten-class object, 2003 UY12. Based upon the volume of astrometric observations submitted, observatory code 683 was the world's eighth most productive asteroid astrometry station.

New and Improved SETI@home will Form the Backbone of Distributed Computing Network

Posted by Amir Alexander on 2003/09/25 12:00 CDT

SETI@home and BOINC are gradually converging, and the benefits for both are substantial. While SETI@home enjoys the increased flexibility of the BOINC platform, it brings to BOINC something of inestimable value to a distributed computing project: millions of SETI@home users, willing to use their computers' processing power for the advancement of scientific research.

Analyzing the Reobservations

Posted by Amir Alexander on 2003/07/18 12:00 CDT

SETI@home chief scientist Dan Werthimer and his team went back to Arecibo to reobserve the most promising candidate signals detected by the project so far. Unlike most of the year, when SETI@home piggy-backs on the regular operations of the telescope, this time the Werthimer's crew had the full use of the resources of the giant dish.
