It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million year. But when will the next one be? Will there be any warning signs?

Satellites provide important data on climate and the environment every day. According to initial tests, new software from RUAG Space can determine the real-time position of a satellite in space ten times more accurately than was previously possible. More accurate positioning data leads to more precise satellite data and helps to avoid space debris.

A team of physicists has discovered how DNA molecules self-organize into adhesive patches between particles in response to assembly instructions. Its findings offer a "proof of concept" for an innovative way to produce materials with a well-defined connectivity between the particles.

Tuesday, 02 November 2021 07:11
A federal agency has yet again pushed back a final decision on whether to allow the construction of a launchpad for commercial rockets in coastal Georgia.
The Federal Aviation Administration plans to release its decision on Spaceport Camden by Dec. 15 rather than this Wednesday, agency spokesman Steve Kulm said. An agency statement cited a delay caused by "ongoing consultation efforts." The final determination was originally expected at the end of July but now has been delayed at least three times.
Camden County, in the southeast corner of Georgia, wants to build the nation's 13th licensed commercial spaceport and has spent nearly 10 years and $10 million pursuing that goal. The FAA in June issued an environmental impact study that concluded building the spaceport would be its "preferred alternative."
That drew pushback from the National Park Service and its parent agency, the U.S. Department of the Interior. In a July 22 letter to the FAA, the Interior Department said a chance of rockets exploding and raining fiery debris onto the federally protected wilderness on Cumberland Island creates an "unacceptable risk.
