Blue Origin's NS-29 New Shepard rocket is scheduled to launch Feb. 4 after a weeklong delay. Here's what to know

For the first time, Blue Origin put its New Shepard suborbital rocket ship through a couple of minutes' worth of moon-level gravity.

If all goes according to plan, New Shepard — a reusable rocket-capsule combo — will lift off on Tuesday from Blue Origin's West Texas launch site at 11:00 a.m. EST (1600 GMT; 10:00 a.m. local Texas time). The company will stream the action live, beginning 15 minutes before liftoff.
