You should have read the apocalyptic conspiracy theories in The Guardian comments section! However, I did learn something new reading a comment about kinetic bombardment and "Lazy Dog". Never knew these existed.

Somewhat more mundane than "Rods from God", but I wonder if it's a challenge to keep the X-37's tires in workable condition through two years of thermal cycling in a vacuum.

Don't let the Guardianistas see this, then...

(It's real. by the way. Back in the days of SOVs and SMVs...)

I wonder if the launch of NROL-76 a few days before was purely coincidence....

Possible reason it landed at Kennedy, rather than Vandenberg, is that the weather has been crap here this weekend.

In all seriousness - although I have no evidence, I believe the US has anti-satellite weapons in orbit.
The first target in many war scenarios is the satellite constellation of an opponent (if they have one) - to blind them.
We know that technology to conceal satellites from ground observation has existed for decades.
I think they'll have some form of micro sleeper satellites, with stealthy coatings or inflatable shields, perhaps with small explosive charges or simple kinetic weapons that wouldn't breach current space treaties - and could be tasked at short notice to take out an opponents IMINT or SIGINT satellites.
Others also appears to be exploring the same technology.
Ground based ASAT missiles have limitations even attacking satellites in LEO, and GEO orbit satellites are effectively out of their reach.
They're out there... I tell ya...!

That thought crossed my mind also but I imagine there's a system that ensures that they are fit for landing after a long duration flight.

There was a tyre blowout on the first flight which damaged the underside.

Doing some reading the pressure differential between orbit and ground is 4.5% against the internal pressure, far far less than that experienced on touchdown and due to heating during roll-out, and not a significant factor. Similarly the temperature differential is not sign I can't compared to landing and, being inside the vehicle, they don't get exposed to direct sunlight and experience a constant change. As to the temperature they drop to, the problem in space is getting rid of heat, not the cold, and they never go near their lower limits.

X-37C -

Boeing X-37C Crew Vehicle

Manned shuttle type missions could be the thing again albeit much more comfortable than Soyuz from Kazahkstan...

Laughingly I think Dale Brown mentioned a similar reusable space transportation vehicle in one of his high tech thrillers,

cheers

This was on my local TV the other day. Gregory Peck looking very serious.

But hey what do I know
Makes perfect sense when you've seen the high end xilinx video processing chips used in the devices that will be using terrain recognition.

Or updates to the gravity maps produced during the space shuttle missions.

If so, it's only covered a subset of the data. SRTM orbital inclination was something like 60 degrees, whereas this one was closer to 40 degrees.

I suspect what the X-37b is doing will eventually leak.
The cousins have hordes of people with Top Secret clearances - and over the medium and long term - they can't keep a major secret under wraps.

Well apparently the " Stealth Blackhawk" is still under wraps after all these years ( Hat , Coat etc. )

Nothing to say it isn’t simply building confidence in the capability and may just be sensored up as a development type. Then again, nations have previously launched satellites which have been alleged to spy on and even disable other forint sat capability. Could even be a more secure means of firmware update to present assets.

Be interested to see if there have been numerous inclination changes during flight which would point towards this “sort of thing”. There have been a few avid space geeks whom have managed to locate the vehicle during missions.

Confirmation that those sonic booms heard over Florida this morning was the return of the X-37B to the SLF (Shuttle Landing Facility) from its OTV-6 mission.

Completed 900 days in space!
