Postdoc Josh Borrow and his colleagues used simulations to explore how early-universe galaxies born inside alternative dark matter halos start out, and what happens as they grow, reports Lyndie Chiou for Scientific American. “The simulations also revealed a new discovery: a connection between alternative dark matter types and starbursts, periods of extremely rapid star formation inside a galaxy.”
SpaceX Crew-6 Mission Commander Stephen Bowen MS ’93 recently answered questions from Cohasset Public School students live from the International Space Station, reports WBZ. "The Earth is always amazing to look at," Bowen told the students of his experience in space.
Using the James Webb Space Telescope (JWST), postdoc Rohan Naidu and his colleagues will be using a giant cluster of galaxies to “gravitationally magnify the light of some smaller objects up to 750 million years after the big bang,” reports Jonathan O’Callaghan for Scientific American. “The goal is to look for clumps of primordial gas, which could contain clusters of Population III stars—the first stellar generation thought to have lit up the universe,” writes O’Callaghan.
Researchers at MIT are developing a new way to use electric thrusters, reports Freethink. “Electric propulsion actually has the benefit of maximizing the amount of room that you have on a spacecraft so you can use it for this useful payload as opposed to just propellant,” says Prof. Paulo Lozano.
Postdoctoral Scholar Michelle Kunimoto speaks with BBC CrowdScience presenter Marnie Chesterton about the transit technique used to find distant worlds. “The idea behind the transit method is, as a planet is passing in front of a star as it orbits, it will block a small portion of that star’s light,” explains Kunimoto. “So if we are measuring the brightness of our star with the telescope, we can look for these temporary decreases in the brightness of stars over time.”
Virginia Norwood ’47, an aerospace pioneer who designed and championed the scanner used to map and study the earth from space, has died at 96, reports Dylan Loeb McClain for The New York Times. Using her invention, the Landsat Satellite program has been able to capture images of the planet that provide “powerful visual evidence of climate change, deforestation and other shifts affecting the planet’s well-being,” writes McClain.
Prof. Danielle Wood speaks with NPR Shortwave co-host Aaron Scott about the future of space sustainability. “I hope that humans pause and note that the actions we're taking now and in the next 10 years really are going to be decisive in the relationship between humans and our planet, and humans and other locations, like the Moon,” says Wood.
Prof. Tanja Bosak speaks with Scientific American reporter Jonathan O’Callaghan about the possibility that the soil samples collected by NASA’s Perseverance Rover on Mars could contain evidence of ancient Martian life.
NPR reporter Kaitlyn Radde spotlights the life and work of Virginia Norwood ’47, “a founding figure in satellite land imaging who developed technology to scan the surface of the moon for safe landing sites and map our planet from space.” Norwood was known as the "Mother of Landsat” for her work developing the Multispectral Scanner System that flew on the first Landsat satellite.
Virginia Norwood ’47, “a pioneering aerospace engineer who used design innovations, emerging technologies and seasoned intuition in projects that scanned the lunar surface for safe Apollo landing sites and mapped the Earth from space with digital imagery never before seen,” has died at 96, reports Brian Murphy for The Washington Post. “Over a four-decade career that began with slide rules and moved into the age of computer modeling, Ms. Norwood became known as a resourceful problem solver who often hit upon simple but effective solutions,” Murphy writes.
Prof. Nicholas de Monchaux speaks with New York Times reporter Vanessa Friedman about NASA’s newest spacesuit. The suit is “the costume for the drama we project into space,” says Monchaux. “[The way we] put ourselves into the heavens.”
Postdoc Saverio Cambioni speaks with Andrew Corselli of Tech Briefs about NASA’s DART mission, which was aimed at testing a method to protect Earth in case of an asteroid impact threat. “DART showed that it is technologically possible to intercept and impact a sub-kilometer asteroid, with limited prior knowledge of its shape and surface properties,” Cambioni explains.
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.”
