Aeronautical and astronautical engineering

In an article for The Conversation, Prof. Steven Barrett details how he was inspired by science fiction movies to create an airplane that makes no noise, has no moving parts and does not require fossil fuels to operate. Barrett explains that he hopes the new technology “could be used in larger aircraft to reduce noise and even allow an aircraft’s exterior skin to help produce thrust.”

Inspired by “Star Trek,” Prof. Steven Barrett has developed a new silent airplane that does not require fossil fuels to operate and is powered by ionic wind thrusters, reports Malcom Ritter for the AP. Ritter explains that the technology that powers the plane could eventually be used “in airplane-like drones that perform tasks like environmental monitoring and surveillance.”

Writing for Popular Science, Rob Verger highlights how MIT researchers have built and flown “a radically different type of plane that is thrust through the air using just electricity and the movement of ions, a type of silent drive without moving parts out of science fiction.”

Scientific American reporter Angus Chen writes about how Prof. Steven Barrett has created the first-ever airplane that is powered by ionic wind thrusters and has no moving parts. “[Barrett] has demonstrated something truly unique,” says Prof. Mitchell Walker of the Georgia Institute of Technology.

Boston Herald reporter Jordan Graham writes that an MIT startup, Accion Systems, is developing a new satellite propulsion technology that could make engines significantly cheaper and more efficient. Graham explains that, “Accion uses a propulsion system called ion electrospray, which shoots ions through holes in the thruster, sending the device in the opposite direction in space.”

Prof. Dava Newman speaks with Space.com reporter Meghan Bartels about her work designing the next generation of spacesuits. "We're going to Mars not to sit in the habitat — we're going there to explore," says Newman. "We don't want you to fight the suit. We want you to find life on Mars."

Graduate student James Clark speaks with Boston Globe reporter Andres Picon about his study that provides evidence laser technology could be used to attract aliens. “A laser produces all of its power in one wavelength,” explains Clark, “so the way that it’s detectable is not that it’s more powerful than the sun, but that it’s very distinct from the sun.”

Fast Company reporter Melissa Locker writes that a study by MIT researchers examines the feasibility of harnessing laser technology to try to attract the attention of aliens. Locker explains that the researchers found that if contact was made, “lasers could potentially be used to send Morse code-like message via light pulses.”

Writing for Popular Mechanics, David Grossman highlights a feasibility study by MIT researchers that provides evidence that lasers could be used to try to locate aliens. Grossman explains that the light would be targeted toward “areas like Proxima Centauri, the closest star to Earth, and TRAPPIST-1, a star around 40 light-years away with seven exoplanets in orbit.”

USA Today reporter Brett Molina writes that MIT researchers have found laser technology could be used to attract the attention of aliens. The researchers found “creating a 1- to 2-megawatt laser focused through a telescope aimed toward space could produce a light strong enough to stand out from the energy produced by the sun."

UPI reporter Tauren Dyson writes that a new feasibility study by MIT researchers shows that existing laser technology could be used to create a beacon light that could attract attention from as far as 20,000 light years away.

MIT researchers have found that laser technology could be used to attract attention from alien astronomers, reports Becky Ferreira for Motherboard. The researchers found that amplifying an infrared laser could “produce a signal that would outshine the Sun’s infrared emissions tenfold, an anomaly that would stand out to a smart species observing our solar system from a distant exoplanet.”

Boston Herald reporter Jordan Graham writes that MIT researchers have developed an autonomous system that allows fleets of drones to navigate without GPS and could be used to help find missing hikers. “What we’re trying to do is automate the search part of the search-and-rescue problem with a fleet of drones,” explains graduate student Yulun Tian.

Fortune reporter Aaron Pressman highlights how Prof. Julie Shah is working on making human-robot collaboration on the assembly line more effective through the use of collaborative robots, dubbed cobots. Pressman writes that Shah “is working on software algorithms developed with machine learning that will teach cobots how and when to communicate by reading signals from the humans around them.”

WCVB’s Mike Wankum visits the Beaver Works Summer Institute to see how high school students are gaining hands-on engineering experience. Robert Shin, director of Beaver Works, explains that the program is aimed at “inspiring the next generation.”
