CHARLOTTESVILLE, Va. (NRAO PR) — Recent advancements in 3D printing (also known as additive manufacturing) for metallic structures make it possible to print all-metal electromagnetic devices—like antennas and waveguides—on demand. A new partnership between the National Radio Astronomy Observatory, headquartered in Charlottesville, Virginia, and Optisys, LLC, headquartered in West Valley City, Utah, will explore the potential for leveraging this technology for radio astronomy applications.
The elevated instrument platform of the 305 meter (1,000 foot) telescope at the Arecibo Observatory in Puerto Rico collapsed overnight, crashing into the dish below and adding to the gloom over the previous decision to decommission the iconic facility.
In a tweet, the National Science Foundation (NSF) said there were no injuries reported in the collapse.
Engineers are reviewing the new damage and assessing how to best stabilize the facility.

A main cable that supports the Arecibo Observatory broke Friday at 7:39 p.m. Puerto Rico time.
Unlike the auxiliary cable that failed at the same facility on Aug. 10, this main cable did not slip out of its socket. It broke and fell onto the reflector dish below, causing additional damage to the dish and other nearby cables. Both cables were connected to the same support tower. No one was hurt, and engineers are already working to determine the best way to stabilize the structure.

Flat Fabrication of Progressively Self-Assembling Space Systems
Davide Guzzetti Auburn University
This project aims to study the feasibility of integrating an array of microchips with space satellite functions, or ChipSats, on a multifunctional shape memory polymer (SMP) bus that is capable of self-folding when exposed to solar radiation.
This technology may enable the flat fabrication of kilometer-sized antenna arrays for radio astronomy that self-transform into the operative configuration once in orbit.
The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
