Wide-field Infrared Survey Explorer

So, uh, this will be the most colorful survey of the sky that's ever been done.

Our predecessor mission that was last doing a survey in infrared was the WISE mission, and that collected only four different wavelengths of light on the entire sky.

Oh, wow.

And so it's a big step up in the quality and depth of the, the science that we're collecting.

We, we're pretty lucky that we get to talk to it all the time, and it, it is a different type of operations than those deep space vehicles that you only talk to, you know, maybe once a week.

So SPHEREx is surveying the entire sky every six months.

Is this a new technology or does it use technologies used on Hubble, Spitzer, James Webb Telescope, WISE or other space telescopes?

It's a little bit of both.
