Starship SN5 Flew, So Let’s Check In on Some Predictions

Main Engine Cut Off

Yesterday evening, Starship SN5 took a glorious flight up to 150 meters and down to its landing pad. It was a joy to watch, and other than a small engine fire that probably isn’t much to worry about, looked like a wonderfully successful test, complete with off-axis thrust, attitude control, and great sound. I figured now is as good a time as any to check in on some predictions Tim Dodd and I made back in February.

Thank You to June Supporters!

Satellite Bonanza: Ten GEO Satellites Ordered in Prep for C-Band Clearing, More Coming

Main Engine Cut Off

Intelsat ordered four from Maxar and two from Northrop Grumman, while SES ordered two each from Boeing and Northrop Grumman with two more yet to be announced. This is huge for satellite manufacturers who have been hurting in recent years after a dip in orders. This is all in preparation for clearing C-band spectrum that has been reallocated towards 5G deployment in the US and will be auctioned off late this year.
