Sense Sonnet - Pumper

Asteroid Bound Dawn

I am Dawn, a space probe Earth sent
To study the asteroid belt,
Where two woulda been planets went,
Vesta and Ceres always felt.
Two thousand eleven I got
To Vesta, shouting no hello.
Orbited round and snooped a lot.
Fourteen months and 'twas time to go
On to Ceres. If all goes well,
I'll be the first to beat the odds,
Doing double duty - do tell!
First time orbit - two ET bods.

It's been a trip to go and find
Two close encounters of 'roids kind.
