Indian American scientist hoping to be first woman to jump from stratosphere

Swati Varshey has a PhD in materials science from the Massachusetts Institute of Technology and has made over 1,200 jumps with a speciality in vertical freefall, according to Space.com.

Swati Varshey has been selected as one of the three candidates selected by the Hera Project of Rising United that seeks to empower women in science and technology, the organization has announced. - If she makes it to the skydive in 2025, Hera Project expects her to break four current records: The free fall record by 1.1 kilometer from the highest altitude; endure the longest free fall time; break the sound barrier unaided by 264 kph; and the highest crewed balloon flight by over 1 kilometer. “At Rising United, we’re embarking on a historic journey, shattering records and ceilings to advance women’s equality and inspire young women’s interest in STEAM education”, the organization said.

Aerial Undulation’s Role In Flying Snake Glides Revealed

The paradise tree snake mid-glide. Photo by Jake Socha. When the paradise tree snake flies from one tall branch to another, its body ripples with waves like green cursive on a blank pad of blue sky. That movement, aerial undulation, happens in each glide made by members of the Chrysopelea family, the only known limbless vertebrates capable of flight. Scientists have known this, but have yet to fully explain it. For more than 20 years, Jake Socha, a professor in the Department of Biomedical Engineering and Mechanics, has sought to measure and model the biomechanics of snake flight and answer questions about them, like that of aerial undulation’s functional role. For a study published by Nature Physics, Socha assembled an interdisciplinary team to develop the first continuous, anatomically-accurate 3D mathematical model of Chrysopelea paradisi in flight. The team, which included Shane Ross, a professor in the Kevin T. Crofton Department of Aerospace and Ocean Engineering, and Isaac Yeaton, a recent mechanical engineering doctoral graduate and the paper’s lead author, developed the 3D model after measuring more than 100 live snake glides. The model factors in frequencies of undulating waves, their direction, forces acting on the body, and mass distribution. With it, the researchers have run virtual experiments to investigate...
