Blue Origin, the space company owned by Jeff Bezos of Amazon.com fame, flew their New Shepard reusable suborbital rocket vehicle for the third time last Saturday. The rocket takes off with the rocket booster and crew capsule connected together but just above 100 km in altitude the two separate. The crew capsule falls back to earth for a parachute landing while the booster does a vertical tail-first powered return using its liquid hydrogen, liquid oxygen engine.
In this test flight they decided to wait till the booster was at low altitude before turning on the engine. As you will see in the video, it comes down really fast and then brakes smoothly for a soft landing:

the bizarre methane-filled seas and soaring dunes of Saturn’s largest moon, Titan. Recent advances in our understanding of this planet-sized moon provide enough information for authors to paint a realistic picture of this truly alien world.
NASA’s New Horizons spacecraft spied several features on Pluto that offer evidence of a time millions or billions of years ago when – thanks to much higher pressure in Pluto’s atmosphere and warmer conditions on the surface – liquids might have flowed across and pooled on the surface of the distant world.
“In addition to this possible former lake, we also see evidence of channels that may also have carried liquids in Pluto’s past,” said Alan Stern, Southwest Research Institute, Boulder, Colorado—principal investigator of New Horizons and lead author of a scientific paper on the topic submitted to the journal Icarus.
This feature appears to be a frozen, former lake of liquid nitrogen, located in a mountain range just north of Pluto’s informally named Sputnik Planum. Captured by the New Horizons’ Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Pluto on July 14, 2015, the image shows details as small as about 430 feet (130 meters). At its widest point the possible lake appears to be about 20 miles (30 kilometers) across.
