Looking Earthward From Space

meteorologists and other specialists under the banner of a new discipline called Earth system science. It would launch over two dozen satellites designed to study all aspects of Earth’s climate.

Additional information. Check out the details.

Of all human spaceflight, Apollo 8 may have best demonstrated NASA’s capacity to change human perspective. In reflecting upon that mission, the first circumnavigation of the moon, the astronaut Bill Anders, one of three on board, said, ‘We came all this way to explore the moon, and the most important thing is that we discovered the Earth.’ Anders had taken the photograph that came to be known as ‘Earthrise,’ the first image of the planet captured by a human from beyond Earth’s orbit. As his fellow crew member Jim Lovell would point out, ‘Suddenly, everybody could see the Earth as it truly is: a grand oasis in the vastness of space.’

Japanese supply ship heads to space station

An unmanned Japanese space capsule is headed to the International Space Station filled with cargo including food, experiments and new batteries.

The craft was launched from the Tanegashima Space Centre in southern Japan. It will take four-and-a-half days to reach the space station.


At 1:52pm ET, a Japanese cargo ship loaded with 5+ tons of supplies, water, spare parts and @ISS_Research experiments successfully lifted off to the @Space_Station.

What the #$%& is lidar?

Yes, my first thought was “but surely there are already dozens of ‘definitive’ books on lidar?!?!”

My second thought was “what the eff is lidar and do i really need to read a whole book to find out?”

First: I’m not a lidar expert. I’m a writer who likes to relay technical stories in nontechnical terms. I have written a book about lidar called ‘The Laser That’s Changing the World.’ It is by no means ‘definitive.’ That’s by design.

A definitive book on lidar, covering a history dating 30 years before the invention of the laser and touching upon all the innovations and innovators across a staggering breadth of science, engineering, and commerce, would take thousands of pages and end up unreadable.
