Princeton University Concerts (PUC) is expanding its digital offerings for the remainder of the 2020-21 season to replace planned in-person concerts, many of which will be rescheduled to future seasons.
The university’s performing arts series has recast all of its virtual programming to directly address socially relevant topics. This includes: a new podcast series, Breathe in Music, bringing PUC’s popular Live Music Meditation series to a digital format; a new series of conversations with musicians and prominent arts thinkers about the impact of COVID-19 on the performing arts hosted by multidisciplinary artist and WNYC host Helga Davis; the release of new video episodes of mezzo-soprano Joyce DiDonato’s Sing for Today, in which the opera star responds to current events through the lens of song and conversations; and virtual performances and live Q&As with world-renowned musicians
Solar flare-style rocket thruster âcould send astronauts to outer solar systemâ 29 Jan 2021

Fatima Ebrahimi, a principal research physicist at Princeton Plasma Physics Laboratory (PPPL) in New Jersey, proposed the concept. The thruster would apply magnetic fields to cause particles of plasma to shoot out the back of the rocket, propelling it forward. Current space-proven plasma thrusters use electric fields to propel the particles.
Dr. Fatima Ebrahimi has invented a new fusion rocket that could one day take humans to Mars
Dr. Fatima Ebrahimi, who works for the US Department of Energy s Princeton Plasma Physics Laboratory (PPPL), has invented a new fusion rocket that could one day take humans to Mars.
The device uses magnetic fields to shoot plasma particles from the back of the rocket and propel the craft through space.
Using magnetic fields allows scientists to tailor the amount of thrust for a particular mission and astronauts change the amount of thrust while piloting to distant worlds.
Ebrahimi s innovation would also take space faring heroes to the Red Planet 10 times faster than current rocket thrusters that use electric fields to propel the particles.

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist at the U.S. Department of Energy s (DOE) Princeton Plasma Physics Laboratory (PPPL).
The device would apply magnetic fields to cause particles of plasma, electrically charged gas also known as the fourth state of matter, to shoot out the back of a rocket and, because of the conservation of momentum, propel the craft forward. Current space-proven plasma thrusters use electric fields to propel the particles.
