The place agency NASA is waiting to reestablish get hold of with Voyager 2. That spacecraft has been hurtling absent from the Earth given that 1977. In modern weeks, a programming mistake on Earth prompted the company to drop get hold of, leaving NASA waiting for an automated reset to kick in this tumble. Suzanne Dodd, who manages Voyager 2 from a California lab, says it truly is now 13 billion miles away recording information and also all set for get in touch with just in situation.

SUZANNE DODD: It does have this gold file on it that contains the sounds of our earth Earth, and it is on this spacecraft for any upcoming becoming to find it.

INSKEEP: You know, when I to start with browse about the gold document as a kid, I feel, I puzzled, would, you know, any alien lifestyle variety – would they know how to enjoy it?

But we can measure the natural environment we are touring through. So we evaluate the density of the plasma. We evaluate the vitality stages of charged particles that we see. We measure the photo voltaic wind and the absence of solar wind.

INSKEEP: So what took place with the antennas just lately?

DODD: Nicely, it was a bit regrettable. We sent a command to update its pointing towards the Earth, and there was an error in that command. And so it’s pointed about two levels off of the Earth. And from the length that Voyager 2 is, close to 13 billion miles from us, that
