vertical Landings
SpaceX
Vertical landings have been pivotal in enabling the rapid reusability of SpaceX's Falcon 9 rocket, significantly reducing launch costs and increasing flight cadence.
On December 21st, 2015, a Falcon 9 made history by achieving the first-ever vertical landing of an orbital-class rocket,
marking a major milestone in reusable launch technology. By recovering and refurbishing first-stage boosters, which constitute the most expensive part of the rocket,
SpaceX has been able to lower the cost of space access. As of April 2025, Falcon 9 boosters have successfully landed 291 times, demonstrating the effectiveness of this approach.
While this is impressive, the second stage is still expended, much greater savings would be acheived by a fully reusable system2.
The Falcon 9 booster produces a sonic boom before slowing down to land. Here is a recording:

As of April 27th 2025, the next scheduled crewed flight of a Falcon 9 rocket will be the Axiom Mission 4 (Ax-4) mission on May 29th 2025.3 This clock is counting down the seconds assuming a launch time of Noon. Countdown created on countingdownto.com. License information here.
SpaceX is now scaling up the concept to the largest, most powerful rocket ever launched. Whimsicly named "Starship" it is designed for point-to-point, orbital, and inter-planetary transportation. While it is still in the developemental stages, the goal is full reusability.4
Blue Origin
Blue Origin's New Shepard is a fully reusable suborbital rocket offering brief spaceflights using vertical landings5. Though limited to short missions, it laid the groundwork for New Glenn ...
a heavy-lift, partially reusable rocket that uses propulsive landings to lower launch costs. In January of 2025, New Glenn completed its first orbital mission,
with the goal of marking Blue Origin's leap into reusable orbital spaceflight.6 However, the first attempted landing of the first stage failed, which isn't a huge setback.

Horizontal Landings
Virgin Galactic
Virgin Galactic made history with SpaceShipOne-the first fully reusable crewed spacecraft-which clinched the $10 million XPRIZE in 2004.
Building on that, they created SpaceShipTwo, a sleek spaceplane launched mid-air by a custom jet. Both stages take off and land on runways, and SpaceShipTwo's unique feathering system,
inspired by a shuttlecock, ensures a smooth and stable reentry from suborbital space8. [Image: SpaceShipOne_on_touch_down_photo_D_Ramey_Logan.jpg. Spaceship One. Wikimedia Commons public domain.]
Sierra Space
Sierra Space developed Dream Chaser. It's a reusable lifting-body spaceplane designed for up to 15 missions, offering runway landings for rapid turnaround and reduced refurbishment costs.
Unlike the Space Shuttle, which required extensive maintenance of its fragile silica-based heat tiles, Dream Chaser employs an advanced Thermal Protection System.
They developed it in collaboration with Oak Ridge National Laboratory. This system utilizes silicon-carbide-based composite tiles which are more durable and cost-effective,
maintaining their aerodynamic shape over multiple reentries9. [Image: Dream_Chaser_ALT-2_free_flight_landing_2.jpg. Dream Chaser lansing. Wikimedia Commons public domain.]
Cost-based reusability
United Launch Alliance
Though not yet demonstrated, ULA plans to implement what CEO Tory Bruno calls "smart reusability" on its Vulcan Centaur rocket.
The concept focuses on recovering only the most expensive part (the engines) using an inflatable heat shield called LOFTID, while discarding the rest of the rocket10. [GIF annimation: File:LOFTID inflates in space while attached to Centaur upper stage.gif. Wikimedia Commons public domain.]
