Scientists slow the speed of light

By Kenneth Macdonald

A team of Scottish scientists has made light travel slower than the speed of light. 

They sent photons - individual particles of light - through a special mask. It changed the photons’ shape - and slowed them to less than light speed. 

The photons remained travelling at the lower speed even when they returned to free space. 

The experiment is likely to alter how science looks at light.

SpaceX announced they are planning to send their Red Dragon capsule to Mars as soon as 2018

To send Red Dragon spacecraft to Mars, SpaceX is building a mega-rocket called Falcon Heavy. Based on the company’s successful Falcon 9, Falcon Heavy consists of three core rocket stages, each of which is equipped with landing legs for reusability. They would use the capsule’s thrusters to make a landing. 

This artist’s illustration shows how the capsule could enter Mars’ atmosphere. SpaceX has successfully returned their capsules to Earth during space station resupply missions for NASA.

The Dragon can carry seven astronauts to and from destinations like the International Space Station (not yet a manned mission to Mars I’d guess 😄). Here’s an illustration of the Dragon Version 1 (the new version has some differences), to get the idea:

Getting ready for 8/21/17

I am making a journal as I get ready for the total eclipse of the sun on 8/21/17 and you can find it on http://www.astrotidbits.com.  Irregular posts as I do something new or learn new ways of doing things.

Comets may hold the secret to the origin of life on Earth

We’ve studied life on Earth extensively, but we still have no idea where it came from. Some scientists think it may have spontaneously arisen on Earth by some unknown process. Others think the ingredients for life were delivered here by comets crashing into Earth in the early days of the solar system. The latter theory just got a huge boost.
