NASA’s Psyche spacecraft blasted off this morning at 10:20 am Eastern time and is now en route to its namesake metal-rich asteroid. The long-delayed mission will examine the asteroid with a suite of scientific instruments and determine whether the hunk of rock was the core of a baby planet that never fully formed.

But that’s not Psyche’s only mission. The probe also carries an important experiment. It will test a futuristic laser technology for transmitting large amounts of data to and from faraway spacecraft that’s called the Deep Space Optical Communications project, or DSOC. It’s expected to deliver much-improved data rates, with 10 to 100 times the capacity of radio
