SpaceX completed a doubleheader today; not that many people close to the launch site saw it.

At 6:13 PM, Falcon 9 lifted off out of a gloopy fog at Launch Complex 39A and lofted the Maxar 4 / WorldView 5 and WorldView 6 satellites into orbit on the second successful mission of the day for the company. The rising rocket was seen up the east coast as far as New York City, but here locally, fleeting glimpses was the order of the day.

From the outset of space flight, engineers dreamed of reusing rocket boosters. This 1964 study, written by W. E. Ruhland and R. H. Lipp of the Chrysler Corporation’s Space Division, lists some possible methods to make that happen. Chrysler was the prime contractor for the S-IB first stage.

As a reminder, the S-IB first stage was for the smaller Saturn variant, and was the rocket that launched Apollo 7, Apollo Soyuz Test Project and as crew transportation during the Skylab program. Its booster had eight engines powered by RP-1 kerosene and liquid oxygen. It used the Saturn S-IV as its second stage, and an Apollo CSM if it were being used on a crewed mission.

In the world of aerospace engineering, even the smallest miscalculation can lead to catastrophic failure. And in the past few years, a phrase has emerged as a humorous way to describe those unfortunate events: “rapid unscheduled disassembly,” often shortened to RUD. This technical-sounding euphemism, often deployed in the aftermath of rocket explosions, has become a staple in modern spaceflight jargon, and is widely used when a rocket fails. But where did the phrase come from?

Blue Origin NG-1 Liftoff

In a milestone for space exploration and commercial spaceflight, Blue Origin’s New Glenn rocket successfully lifted off from Launch Complex 36 at Kennedy Space Center on Thursday. 

At 2:03 a.m. EST, the 320-foot-tall New Glenn finally roared to life after two holds and was propelled by seven Blue Origin BE-4 engines fueled by liquid oxygen and methane.

Spectators crowded the beaches and riverfront to witness the spectacle, as the rocket ascended gracefully into a cloudy sky obscuring a nearly full moon.
