Aeronautical and astronautical engineering

MIT researchers have developed Robust MADER, an updated version of a previous system developed in 2020 to help drones avoid in-air collisions, reports Brian Heater for TechCrunch. “The new version adds in a delay before setting out on a new trajectory,” explains Heater. “That added time will allow it to receive and process information from fellow drones and adjust as needed.”

MIT has ranked first in 11 different academic fields in the latest QS World University Rankings, reports Michael T. Nietzel for Forbes.

Researchers at MIT have predicted that without improvements in hardware efficiency, energy consumption and emissions from autonomous vehicles could be “comparable to that of data centers today,” reports Sarah Wells for Popular Mechanics. “In order to reduce the future carbon footprint of AVs, scientists will need to make the computing systems of AVs, including smart sensors, far more efficient,” writes Wells. 

Stephen Bowen MS ’93 and Warren Hoburg BS ’08 have joined the Crew-6 mission to the International Space Station (ISS), reports Susannah Sudborough for Boston.com.  During their six-month period aboard the ISS, which began on March 2, “they will conduct over 200 science experiments and technology demonstrations,” writes Sudborough.

Daily Beast reporter Meredith Bagby spotlights the life of Ron McNair PhD ’76 and his legacy as one of NASA’s first black astronauts. “Astronaut, saxophonist, and karate black belt Ron McNair overcame an impoverished childhood in segregated Lake City, South Carolina to earn a Ph.D. in physics from MIT and become one of NASA’s first Black astronauts,” writes Bagby. “Although Ron’s path to NASA was nearly derailed because of systematic racism and inequality, he found inspiration in the Black leaders around him and persevered.”

Ronald McNair PhD ’76 was a part of NASA’s class of 1978, which was the first group of astronauts to include women, people of color, and scientists, reports Alexandra Witze for Nature. The class of 1978 “was a time of huge change for NASA,” writes Witze. “It was time for a new type of astronaut for a new type of spaceship.”

Prof. Sara Seager and her colleagues write for Physics Today about how the SpaceX Starship could help transform astrophysics missions. “Assuming it is successful, Starship will dramatically enhance our space capabilities in ways that will qualitatively alter how astrophysics missions can be built,” write Seager and her colleagues.

Research scientist Mary Knapp and her collaborators are working on a concept for The Great Observatory for Long Wavelengths (Go-LoW), a space-based observatory comprised of small satellites aimed at making low-frequency radio waves visible, reports Ashley Strickland for CNN. “I learned back in my undergrad days that there was this part of the spectrum we couldn’t see,” Knapp explains. “It really just struck me that there was this unexplored part of the universe, and I want to explore this part of the sky for the first time.”

An MIT study has found that the wide spread adoption of self-driving cars could lead to increased carbon emissions, reports Rima Sabina Aouf for Dezeen. “The study found that with a mass global take up of autonomous vehicles, the powerful onboard computers needed to run them could generate as many greenhouse gas emissions as all the data centers in operation today,” writes Aouf.

A new study by MIT researchers finds that “the energy required to run computers in a future global fleet of autonomous vehicles could produce as much greenhouse gas emissions as all the data centers in the world,” reports Sharon Udasin for The Hill. The researchers found that “1 billion such cars, each driving for an hour daily, would use enough energy to generate the same amount of emissions that data centers do today.”

Prof. Zachary Cordero and his team are working to develop an in-space manufacturing technique to design a satellite reflector that can monitor storms and precipitation through moisture changes in the atmosphere, reports Ramin Skibba for Wired. “It involves bending a single strand of wire at specific nodes and angles, then adding joints to make a stiff structure,” writes Skibba.

Prof. Steven Barrett speaks with New York Times reporter Paige McClanahan about the pressing need to make air travel more sustainable and his research exploring the impact of contrails on the planet’s temperature. “Eliminating contrails is quite a big lever on mitigating the climate impact of aviation,” said Barrett.

Politico reporter Derek Robertson writes that a new study by MIT researchers finds the computing power required to replace the world’s auto fleet with AVs would produce about the same amount of greenhouse gas emissions as all the data centers currently operating. Robertson writes that the researchers view the experiment “as an important step in getting auto- and policymakers to pay closer attention to the unexpected ways in which the carbon footprint for new tech can increase.”

Graduate student Soumya Sudhakar speaks with BBC Digital Planet host Gareth Mitchell about her new study showing that hardware efficiency for self-driving cars will need to advance rapidly to avoid generating as many greenhouse gas emissions as all the data centers in the world.

Using statistical modeling, MIT researchers have found that the energy needed to power a fleet of fully autonomous EVs could generate as much carbon emissions as all the world’s data centers combined, reports Andrew Paul for Popular Science.
