This article is about rockets. For aircraft capable of vertical takeoff and landing see VTOL.
Pixel is a Quad that took off and landed vertically
Vertical takeoff, vertical landing (VTVL) is a form of takeoff and landing for rockets. Multiple VTVL craft have flown. As of 2012[update], at least six VTVL rocket vehicles are currently under development at four different aerospace companies. VTVL is often proposed as a viable technology for reusable rockets.
VTVL rockets are not to be confused with aircraft, where that class of aircraft which takeoff and land vertically (helicopters, etc.) are known as VTOL aircraft.
Grasshopper was a VTVL first-stage booster test vehicle SpaceX developed to validate various low-altitude, low-velocity engineering aspects of its large-vehicle reusable rocket technology. The test vehicle made eight successful test flights in 2012–2013. Grasshopper v1.0 made its eighth, and final, test flight on October 7, 2013, flying to an altitude of 744 metres (2,441 ft) (0.46 miles) before making its eighth successful VTVL landing.
Vertical landing rocket depicted in 1951 comic, Rocket Ship X.
Vertical landings of spaceships was the predominant mode of rocket landing envisioned in the pre-spaceflight era. Many Science Fiction authors as well as depictions in popular culture showed rockets landing vertically, typically resting after landing on the space vehicle's fins. This view was sufficiently ingrained in popular culture that in 1993, following a successful low-altitude test flight of a prototype rocket, a writer opined: "The DC-X launched vertically, hovered in mid-air ... The spacecraft stopped mid-air again and, as the engines throttled back, began its successful vertical landing. Just like Buck Rogers." In the 2010s, SpaceXrockets have likewise seen the appellation to this popular culture notion of Buck Rogers in a "Quest to Create a 'Buck Rogers' Reusable Rocket."

The DC-X launched vertically, hovered in mid-air at 150 feet, and began to move sideways at a dogtrot. After traveling 350 feet, the onboard global-positioning satellite unit indicated that the DC-X was directly over its landing point. The spacecraft stopped mid-air again and, as the engines throttled back, began its successful vertical landing. Just like Buck Rogers.
