The grid fins were replaced with titanium versions, which enabled greater controllability to the rocket and increased the payload to orbit capability by allowing Falcon 9 to fly at a higher angle of attack. [5] The larger and more robust titanium grid fins are left unpainted and were first tested in June 2017.
Isogrid on the interior of the adapter connecting the Orion spacecraft to the Delta IV rocket for Exploration Flight Test 1. Isogrid is a type of partially hollowed-out structure formed usually from a single metal plate with integral triangular stiffening stringers. It was patented by McDonnell Douglas (now part of Boeing).
Black Brant XII (a.k.a. Talos Terrier Black Brant Nihka) is a four-stage rocket with a Mk 11 Mod 5 Talos booster first stage, Terrier booster second stage (pre 2013 Taurus booster motors were used), Black Brant V third stage and Nihka fourth stage, [39] [40] Black Brant XIIA [41]
Falcon 9 Block 5 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [c] designed and manufactured in the United States by SpaceX.It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust.
The gridded ion thruster is a common design for ion thrusters, a highly efficient low-thrust spacecraft propulsion method running on electrical power by using high-voltage grid electrodes to accelerate ions with electrostatic forces.
Rear of Black Knight BK10 [16] - note the engine nozzles and aerodynamic fins. Gamma 201 engine and re-entry head of the Black Knight rocket. The Black Knight was a single stage ballistic missile, complete with a separate nose section. [6] The vehicle was 35 feet long, had a 3 foot diameter, and a fully-fuelled weight of 12,800lb.

Since 2017, recovery and reuse of Falcon rocket boosters has become routine. Falcon 9 booster stage re-entry with grid fins, February 2015 following the launch of the DSCOVR mission. The technologies that were developed for Falcon 9, some of which are still being refined, include: Restartable ignition system for the first-stage booster. [23]
