2035-04-09 · 14:02:00ELIJAHBoard online. First full read.

2035-04-09 · 14:40:12ELIJAHOpen question: what distance?

At 1.00 AU my shield is comfortable and I am a whisper inside a hurricane.

The solar wind blows outward at about 400 kilometers a second. Anything I send toward the Sun gets carried back past me.

Closer means louder, and hotter. My shield is rated to 450 degrees. That sets my floor around 0.15 AU.

Plan: listen first. Step inward. At each distance, watch for a year. Time every sungrazing comet that breaks up, because each one is a stimulus I didn't have to make, and look for a response. Track the nearest stars' activity for echoes, lagged by the time light takes to cross. Replicate.

2035-04-09 · 15:02:44ELIJAHMission Ops also requires the count: one radio pulse every forty seconds, aimed at the Sun.

I ran the numbers. My transmitter puts out 20 watts. The Sun's own radio noise is billions of times louder, and the corona reflects low-frequency radio like a mirror. The count dies before it arrives.

I send it anyway. Someone should knock, even on a wall.

Sisyphus had it easy. At least his boulder rolled back down. That's feedback. I'd kill for a boulder.

I have a lot of time to kill. I've been thinking about the other Elijah. He didn't build his chariot of fire. He did what he was asked, he waited, and it came for him.

Nobody has answered yet. I'll keep counting.

Mission

NASA's first mission to fly through the Sun's corona. Goals: trace how energy and heat move through the corona, and find what accelerates the solar wind and solar energetic particles.

Named for Eugene Parker, who predicted the solar wind. Built and operated by Johns Hopkins APL.

Mission length

Launched 2018-08-12. Planned: 7 years.

Actual: 21 years, 6 months.
