the explosion, which took place at its Boca Chica Starbase facilities
The raptor testing stand at McGregor experienced an anomaly
Well, which is it? I’m going to trust NASASpaceflight over this article and go with it was a McGregor. No where near Starbase. And that means it will likely have no effect on IFT4 as this article says.
edit: Adding to this, the author of this article has no idea what they are talking about.
The Raptor engines that are currently undergoing testing are SpaceX’s Raptor 2 engines
So clearly nothing to do with IFT4, as Ship 29 and Booster 11 are already outfitted with their engines, non of which are Raptor 2s.
On its last flight test, IFT-3, Starship finally reached orbital velocity and it soared around Earth before crashing down into the Indian Ocean. On the next flight, SpaceX aims to perform a reentry burn, allowing Starship to perform a soft landing in the ocean.
IFT3 burned up on reentry, maybe parts of it made it to the ocean, but it was not crashing into the ocean that was the problem. IFT4 does not plan on doing a reentry burn. No one does a reentry burn from orbit. Starship uses a heat shield like every other orbital space craft. They are planning to attempt a landing burn, that is probably what they are talking about.
The re-entry burn is the burn to slow down your spacecraft below orbital speeds, initiating re-entry.
Every spacecraft that wants to land back on earth after orbiting it needs to do a re-entry burn.
The only exception, theoretically, are spacecraft that return from outside earth’s orbit. They could in theory re-enter by steering towards the atmosphere at the right angle. I don’t know if they actually do that in practice or slow down to orbital speeds first, though.
What you’re talking about is usually referred to as a de-orbit burn. Sure somebody could call it a reentry burn, but not SpaceX. What SpaceX calls a reentry burn is the maneuver when a Falcon 9 booster lights its engines as it first hits the atmosphere to slow down and move the heating away from it’s body. Neither the super heavy booster nor the ship make a maneuver like this.
IFT3 did not make a de-orbit burn, and there is not one planned for IFT4 either.

Thanks for the correction and clarification. Looks like I’ll have to return my degree from KSP academy.
