NASA’s Juno Mission to Jupiter Keeps Surprising Scientists - The Atlantic
The winds at Jupiter’s surface, some of the most powerful in the solar system, influence the planet’s gravitational field, the latest observations show. This means that Jupiter’s signature, crisscrossing bands don’t just exist on the surface of the atmosphere. Jupiter’s wind flows actually extend 3,000 kilometers (about 1,860 miles) below the cloud tops, where the pressure is about 100,000 times that of the atmosphere at Earth’s surface.

Remembering John Glenn, First American to Orbit Earth - The Atlantic
erved in the Senate until 1999. He ran a short-lived campaign for president in 1983, and was accused and later exonerated in a corruption scandal involving four other senators in the early 1990s.

In the late 1990s, Glenn pitched to NASA the idea of studying the effects of spaceflight on geriatric bodies, and offered himself up as a test subject. In 1998, 77-year-old Glenn flew aboard the shuttle Discovery, becoming the oldest person to fly in space. By then, space agencies knew a lot about spaceflight. The U.S. was ferrying astronauts back and forth through the space shuttle program for missions that lasted up to 10 days. In a few years, when the International Space Station would come online, humans would be spending six months or longer in microgravity.

But researchers owe Glenn for their first taste of the experience of true weightlessness. During his orbit around Earth, Glenn reported back to mission control everything he felt. He measured his blood pressure, tested his vision by reading a small copy of the eye chart found at doctors’ offices, and shook his head around to see if he felt nauseous. He found, much to some scientists’ surprise, that he felt fine.

“In fact,” Glenn later wrote about the%2

Hillary Clinton has yet to reveal her position on NASA on the 2016 campaign trail, but stated during her 2008 campaign that she was “committed to a space exploration program that involves robust human spaceflight to complete the Space Station and later human missions, expanded robotic spaceflight probes of our solar system leading to future human exploration, and enhanced space science activities.”
