How do you test a helicopter bound for Mars?

Credit: NASA/JPL-Caltech Caltech grad students helped JPL build a custom wind tunnel in a vacuum chamber for the Mars Ingenuity helicopter The Ingenuity helicopter may be the first vehicle ever to fly on Mars, but Mars was not the first place it has ever flown. Before packaging it up and blasting it to the Red Planet, engineers at JPL gave the helicopter a trial run in a special wind tunnel designed with help from researchers at Caltech. To simulate flying on a planet where the atmosphere is 100 times thinner than Earth’s, a custom wind tunnel was built inside of an 85-foot-tall, 25-foot-diameter vacuum chamber at JPL, which Caltech manages for NASA. Pressure in the chamber was pumped down to approximate the Martian atmosphere, while an array of 441 pairs of individually controllable fans blew on the helicopter to simulate forward flight in the enclosed space.

Montclair State University in Montclair and Stevens Institute of Technology in Hoboken made the announcements on Thursday. Montclair State will require the COVID vaccine for all students who attend undergraduate and graduate classes on campus, whether they are commuter students or students who live on campus.

Murphy wants to create innovative economy How s he doing?

At least, that’s how Gov. Phil Murphy described it when he was candidate Phil Murphy. Getting there isn’t as simple. So said Andrew Zwicker, who doubles as both a physicist and a professor at the famed Princeton Plasma Physics Lab and an assemblyman representing the 16 th District. To coincidence with the release of the first-ever ROI Influencers: Technology list, we asked Zwicker if Murphy’s push to have New Jersey reclaim its global reputation is resonating in the science community. “I would say, ‘We’re getting there,’” he said. That’s hardly a precise, scientific answer, but Zwicker said the question is not easily answered.
