HELLO FROM EARTH Update... As of 7 PM California time tonight (12 PM Sydney time on Friday, April 2), it will be 31 weeks since a radio signal containing 25,878 goodwill text messages—including one by me—was transmitted to the exoplanet Gliese 581d from a giant NASA antenna in Australia. The signal will be 3.5 trillion miles (5.6 trillion kilometers) from Earth. By August 27, the radio beam will officially be 1 light-year distant from our world. Awesome. The Sent Forever signal that was transmitted from the United Kingdom at 8:07 PM (California time) on October 5 last year is now 2.8 trillion miles (4.6 trillion kilometers) from Earth as of this typing. I’ll probably submit another message by late Spring.
