STS-93 - The Golden bullet (thread) 25 years ago yesterday, the Chandra X-Ray Observatory was launched into space aboard Space Shuttle Columbia. While Chandra successfully reached orbit, the ascent was far from nominal. An engine issue almost sabotaged the whole mission...

NACA oil flow of a 35deg swept wing, aspect ratio of about 7, at an angle of attack of 3.7deg and M = 0.92. The line of the strong shock wave is clear. Enter Richard T. Whitcomb…. 1/4

📢 NEWS: Hey space debris, we're watching you from every angle! 👀 ADRAS-J has completed not one, but TWO fly-arounds of the upper stage, confirming the planned capture point has no major damage. This milestone sets the stage for future removal and a sustainable space

One of my fav pics - 25 ( F) Squadron - not the Crusaders Royal Air Force all about symmetry and having just the right amount of equal space between aircraft - lead aircraft Mick Martin and Mark Swan -

What the hell are you supposed to be? Every nerd's fantasy, baby! #Futurama

That's incredible

Goodnight chat

Mach 2.0 is covering 20 miles a minute - few aircraft have been able to achieve this perhaps in the future ⁦Boom Supersonic⁩ ⁦Blake Scholl 🛫⁩ we will be back in the supersonic game - the human race needs to keep pushing forward - life is dull at .82 Mach ! firestreakbooks.com

What's that about sticking the landing? 🥇 12 years ago, my landing on the Red Planet required 76 pyrotechnic devices and had zero margin for error – and my team absolutely nailed it. Do you remember the drama of those "7 Minutes of Terror"?

This Boeing study showed the effect of inadvertent firing of the first-stage rocket motor of one of the Skybolt missiles, on a B-52G. Without corrective action, the analysis showed the bomber exceeding its maximum Mach number (M = 0.93) after 20s; 4s later being #supersonic…1/2

Tonight we mourn the passing of NASA astronaut Jon McBride. Your legacy will live on. Godspeed, Jon.

Pics or it didn't happen? ✅ It's always a little scary being the first, but as always, the team set me up for success!

And it's a dead heat! They're checking the electron microscope. And the winner is... number 3, in a quantum finish. No fair! You changed the outcome by measuring it. #Futurama

And here's the chapter quote for the experimental methods part of my thesis
