Mercury Magazine Winter 2019 cover

Contents and Select Excerpts
Vol. 48 No. 2
Spring 2019

The Spring 2019 issue of Mercury is LIVE!

Featured in this issue:

  • After decades of wondering, the Event Horizon Telescope has revealed what a supermassive black hole really looks like.
  • On April 11, Israel’s dreams of landing its first spacecraft on the Moon ended after Beresheet crashed into the lunar surface—but it wasn’t a failure, not by a long shot.
  • Future lunar explorers will thank the medical research and physiological observations of the NASA astronauts who first set foot on the Moon’s surface nearly 50 years ago.

We also have our regular columnists discussing the history of occultations, how a dizzying amount of science can be gained from studying lunar eclipses, the strange dark matter connection between globular clusters and faint galaxies, plus the dangers of letting a class of students collaborate on a common goal and how the EHT’s first image can be used to teach complex astrophysical phenomena. But that’s not all! Download your copy of Mercury today to read all the latest space news and opinion!

Lifting the Curtain (Feature)

Well, the wait is over. On April 10, a series of international press conferences gave audiences their first-ever view of a black hole: an image of a fuzzy black circle surrounded by a blotchy smear of yellow and red that may transform astrophysics.  But the road to this historic achievement was long and arduous.

The Little Spacecraft That Almost Did (Feature)

From a mission control room near Tel Aviv, Israel, dozens of people waited as the spacecraft Beresheet came out of its orbit around the Moon to attempt a lunar landing. Only three other countries in the world have touched down there safely: Russia, China and the United States. Israel was trying to be the fourth. Engineers and space scientists from SpaceIL and Israel Aerospace Industries (IAI) had already worked together to overcome so many hurdles, financial and technical, since Beresheet’s conception in 2011 that it seemed they couldn’t fail. Their quiet anticipation filled the silent gaps between mission control status updates of the craft’s descent. And then came the devastating words: “We seem to have a problem with our main engine.”

In 1939, visionaries of the British Interplanetary Society (BIS) conceived of a mission that would take three people to the surface of the Moon for 14 days. Unexpectedly, humans did start traveling to the Moon only three decades later, though for stays ranging from just under one day to just over three. Today, nearly fifty years have passed since Neil Armstrong and Buzz Aldrin became the first moonwalkers on July 20, 1969. Plans now beckon for new-piloted lunar missions, this time with stays on the lunar surface at least as long as the BIS two-week vision. Are we actually ready for it?

NASA Uses Color to Catch the Solar Wind (Cosmic Views)

NASA’s sounding rockets light up the Arctic skies.

These aren’t giant alien jellyfish coming to take over the Earth (although I, for one, welcome our new cnidarian overlords); they’re clouds of glowing gas released high over the Norwegian Sea by NASA rockets in order to track winds in the upper atmosphere.
