Rocket recycling – catching rocket stages after launch
Huh, catching a winged first stage booster rocket by the nose, air towing to a landing site, then releasing it again so it can glide to land. Avoids boost-back for recovery (more fuel for main flight), doesn't require a landing site forward in the ground track for the booster either. Catch-and-release, like a big mouth billy bass...

Two-Stage-to-Orbit Transporting System Combining Microwave Rocket and Microwave Thermal Rocket for Small Satellite Launch
Mirabo's air breathing laser lightcraft used lasers to ignite air plasma, this is proposing something similar using microwaves for a rocket booster stage, then beamed microwave thermal for the second stage.

Notable here is the determination that you can cheat the trajectory to favor a higher altitude initial vertical boost, take the gravity loss hit during a cold coast to the second beam director LoS, then have a longer second stage beamed thermal burn. Allegedly 3x payload compared to a UAV air drop launch to a single beam director site?

But how does a common microwave beam work here for first and second stages? Is the first beaming site only a pulsed microwave system? Does microwave PDE even work with continuous wave microwaves?

On the Use of a Pulsed Nuclear Thermal Rocket for Interplanetary Travel | 52nd AIAA/SAE/ASEE Joint Propulsion Conference
Fission pulses do neutron heating of hydrogen propellant to plasma conditions, but you need to liquid metal cool the fuel. Neat result is propellant can get hotter than the fuel due to neutron flux. Though a NTER strikes me as easier to implement...

Enzymatic construction of highly strained carbocycles | Science
Bicyclobutnae is a pain and expensive to make, so hasn't been seriously researched for rocket propellant research, but using e.coli to make it via enzyme catalyst now makes it a biofuel (biorocketfuel?). 8C boiling point versus cryogenic methane makes for an interesting trade study.

Turbo Rocket 8Jul18.pptx - Google Drive
Bringing back the NTTR for another round, this time it looks like it's taking the immense heatsink advantage of LH2 to run a fan/compressor for a SERJ and the turbopumps for an otherwise conventional rocket engine pack. Sorta conceptually similar to RocketLabs doing an end-run by using an electric motor to boost a conventional rocket motor that would have been limited to pressure fed or gas-generator.

SRC "Sea Launch" purchase
So SeaLaunch changes hands again officially, now owned by S7 airlines. Notable is that they appear to want to modifify the SeaLaunch platforms to accommodate Syouz-5 aka Fenix, which also implies use of Federastia, the new passenger capsule.
