Citizen Scientists Spot Super Fast Moving Object In NASA Data
456±27 km/s

The velocities (Table 1) indicate a slightly retrograde motion relative to Galactic rotation (VLSR = −292±19 km/s), with a trajectory directed radially inward (ULSR = 449±28 km/s) and constrained to the Galactic disk (WLSR = −15±11 km s−1)
(1.02 ± 0.06)×10^6 mph (miles per hour), 0.00152 ± 0.00009 c (speed of light), and for comparison
our Sun moves around the center of the Milky Way at a speed of 240 km/s (149 mi/s), or 864,000 km/h (536,865 mph)

...
The median speed is just below the Galactic escape velocity at the Solar radius, with current estimates ranging from 521+46 −30 km/s (Williams et al. 2017, 1.6σ above) to 580±63 km/s (Monari et al. 2018, 1.8σ above)

estimated distance of 125±8 parsecs

Citizen Scientists Spot Super Fast Moving Object In NASA Data

Here is another article on it:
https://thedebrief.org/nasa-citizen-scientists-spot-unidentified-speeding-object-racing-through-space-at-1-million-mph/

I bet it's Jebediah Kerman!

(In early KSP and on at least one clone/similarly-themed Android version, I have been known to almost trivially throw craft into highly retrograde hyperbolic orbits, even without any true gravitational slingshotting. With that, I'd be surprised if there weren't a number of high-relative-velocity ejections of companion bodies (and maybe, afterwards, an Oumuamua-like swing round another system), and some of those will emerge galactically-retrograde to the system at leaves, perhaps even at system-relative speeds that are also retrograde in galaxy-retrograde terms. Properly projecting the path both forwards and back is the key; given the inward travel, and likely age of body, it would more probably be a slow back-escape from an outer system than having started off initially as a fast back-escape from an inner one (over half an orbit ago). Although, given the densities of bodies near the centre, there would be potentially more interactions that might last (to remain not further disturbed, and detectable) for at least a significant part of one orbit.)

Goddamn space DRM locking astronauts out of their return ships.

Whatever the problem was again (square filter in a round hole, like Apollo 13?) it's just been confirmed (properly) that the September launch of Dragon will go up with two less than planned, so that it can return in February with the Starliner pair.

Not good for Boeing's rep, of course, on top of their plane-type incidents.

Seems like Boeing is fucking up constantly these days.

Sadly the Starliner doesn't look nearly as cool as the Event Horizon.
