Weightlessness in space has proved to be a profound challenge to the health of astronauts, whose bodies are finely attuned to the presence of gravity. NASA and the European Space Agency are planning an experiment that will place human subjects in bed for 60 days and spin the beds to determine whether centrifugal force is sufficient to mimic the health-preserving effects of gravity.
Projects and problem solving are the focus of five basic questions young engineers are likely to encounter in job interviews. Charlie Wilgus, general manager for manufacturing and supply chain practices at executive search firm Lucas Group, gives a preview.
Accel.AI, a nonprofit founded by Laura Montoya to reduce barriers to engineering careers in artificial intelligence, includes the Latinx in AI Coalition, which aims to bolster Latin American representation in the field. She believes her efforts are particularly relevant in a job market where minority communities are at risk of losing jobs to automation.
The Defense Advanced Research Projects Agency's Reactor on a Rocket program wants to create a nuclear thermal propulsion system that can be assembled in space. "The program will initially develop the use of additive manufacturing approaches to print NTP fuel elements," according to DARPA's budget proposal.
A Chinese ship maneuvered close to a US destroyer near the Spratly Islands last September, but the US won't let such actions keep it from asserting freedom of navigation in the South China Sea, say Vice Adm. Phillip Sawyer, commander of the 7th Fleet, and Capt. Eric Anduze, commander of the USS Blue Ridge, which recently anchored at Manila Bay after sailing through the disputed waters.
The US Navy and the Royal Fleet Auxiliary Mounts Bay plan to conduct a two-week experiment out of Norfolk, Va., that will put new mine warfare methods to the test in preparation for potential future missions. "We will have the opportunity to advance and refine our performance as ... [a mine countermeasures] task group since MCM is not built around a single platform or sensor; we combine the right sailors and tools to accomplish the mission," Cmdr. Jon Haase said.
During the years it faced the Cold War threat of hundreds of Soviet submarines hunting for US aircraft carriers, the US Navy assigned anti-submarine measures a high priority. One of the principal systems is the surface-launched anti-sub torpedo, which is pneumatically ejected from deck-based tubes to carry a light but lethal warhead to its target.
Ultra Electronics Ocean Systems will develop Next Generation Surface Search Radar qualification systems for US Navy surface warships under a $28 million contract with options that could raise its value by $6.6 million. The company will seek a replacement for obsolete radar systems.
Northrup Grumman will provide engineering support for mission modules aboard the Navy's littoral combat ships under a $45.5 million contract modification. The work will include installation, design and system support.
