Top 5 Times Solar Activity Affected Earth

The Sun sends out a constant stream of particles and energy, which drives a complex space weather system near Earth and can affect spacecraft and astronauts. NASA has chosen five new mission concept studies for further development to study various aspects of this dynamic system. (Credits: NASA)

SILVER SPRING, Md. (NOAA PR) — Over the course of the Sun’s 11-year solar cycle, the star goes through a period of increased and decreased activity. When this activity ramps up, sometimes phenomena such as solar flares and coronal mass ejections (CMEs), where massive amounts of radiation and solar particles erupt out from the Sun’s surface, can wreak havoc if our planet happens to be in the way of the blast.

As NASA celebrates the 50th anniversary of manned Apollo flights leading to the first moon landing in July 1969, the number of astronauts from the program is slowly dwindling away.

Of the 29 men who flew in the Apollo lunar program, 15 are still alive while 14 others have passed away. When the Skylab and Apollo-Soyuz programs are included, there are 21 Apollo-era astronauts still with us while 17 have died.

Video: NASA Remembers Moonwalker, Shuttle Commander John Young

Video Caption: Astronaut John Young, who walked on the Moon during Apollo 16 and commanded the first space shuttle mission, has passed away at the age of 87.

He is the only person to go into space as part of the Gemini, Apollo and space shuttle programs and was the first to fly into space six times — or seven times, when counting his liftoff from the Moon during Apollo 16.

WASHINGTON (NASA PR) — Astronaut John Young, who walked on the Moon during Apollo 16 and commanded the first space shuttle mission, died Friday, Jan. 5, 2018, at the age of 87 from complications of pneumonia. Young began his impressive career at NASA in 1962, when he was selected from among hundreds of young pilots to join NASA’s second astronaut class, known as the “New Nine.”

“Today, NASA and the world have lost a pioneer,” acting NASA Administrator Robert Lightfoot said in a statement. “Astronaut John Young’s storied career spanned three generations of spaceflight; we will stand on his shoulders as we look toward the next human frontier.
