Satellite mega-constellations stir a debate over avoiding catastrophic orbital crashes

The retired commander of the U.S. Strategic Command says the tens of thousands of satellites that SpaceX, OneWeb and Amazon are planning to put into orbit over the next few years will require a new automated system for space traffic management - and perhaps new satellite hardware requirements as well. Retired Gen. Kevin Chilton laid out his ideas for dealing with potentially catastrophic orbital traffic jams at the University of Washington on Friday, during the inaugural symposium presented by UW's Space Policy and Research Center. "We need to develop technologies that will improve space domain awareness, that will enable autonomous… Read More

Sun yields its secrets to Parker Solar Probe

NASA's Parker Solar Probe, having survived its closest encounter so far with the Sun, has sent back a "spectacular trove" of data on its corona, the super-hot outer edge of its atmosphere, scientists said Wednesday. The car-sized probe, launched in August last year, will come within some four million miles (six million kilometres) of the sun's surface during a series of fly-bys at other distances and trajectories over seven years. It is hoped it will allow a better understanding of the solar wind and electromagnetic storms which can cause chaos on Earth by knocking out the power grid.

Cyrus Biotechnology and CRISPR pioneers team up to boost gene-editing therapies

Seattle-based Cyrus Biotechnology says it'll collaborate with the Broad Institute of MIT and Harvard on ways to optimize CRISPR gene-editing techniques for use in developing novel human therapeutics. CRISPR has revolutionized genetics by making it easier to modify the DNA coding in the genome, but more needs to be done to address safety concerns for human applications. Cyrus Biotech and the Broad Institute will work on ways to reduce the potential for the body to mount an immune response against CRISPR-based therapies. MIT biochemist Feng Zhang, one of the pioneers in the development of CRISPR, will be the principal investigator… Read More
