Dr. Phil Korngut, NASA instrument scientist with SPHEREx, has more on the two separate missions that are on the same rocket and talks about what it means and what it will teach us.

If all goes to plan, two NASA missions called "SPHEREx" and "PUNCH" will be sharing a ride to space very soon.

Now scheduled for Sunday, NASA will launch two separate missions on the same rocket, SPHEREx and PUNCH. SPHEREx will help us better understand the origins of our universe, while PUNCH will teach us more about the star that’s closest to home.
