PIX4638389: Killer Whale hitting the beach to hunt - Orcs (Orcinus Orca) who live in groups have developed many hunting techniques. Perhaps one of the most extraordinary is the voluntary failure to catch young sea lions. This technique is used by the group of Mel (a male 9m) in peninsule Valdes. An Orca is coming on land to hunt sea lions. Valdes Peninsula, Argentina / Bridgeman Images

PIX4639516: Permanent station project between Mars and the Earth - Artist view - Mars Cycler - Artist view - Artist view of the Mars Cycler project, a space station placed in cylindrical orbit between Mars and Earth; this project defended by Edwin Aldrin would make a permanent connection between the two planets. A Mars cycler is a permanently orbiting vehicle with a path that alternately brings it near Earth and Mars. Once a cycler has been accelerated into orbit it continues on its own momentum, going back and forth between the two planets, only requiring propellant for occasional course adjustments. A one-way trip between Earth and Mars involves six to eight months of space travel, therefore a large and well-equipped Mars cycler would offer space explorers, and possibly even space tourists, better accommodations for these long journeys. Smaller spacecraft would ferry travelers between the planets and the cycler. A Mars cycler is a permanently orbiting vehicle with a path that alternately brings it near Earth and Mars.

PIX4639597: Mission to Phobos - Appointment in Earth orbit - Phobos mission rendezvous in Earth orbit - An Orion-type space capsule, with three astronauts on board, joins a launcher in Earth orbit to reach Phobos, one of Mars's satellites. An Orion class command module with a crew of three approaches an awaiting rocket in already in Earth orbit destined for Mars' moon Phobos / Bridgeman Images

PIX4639606: Mission to Phobos - Phobos mission ready for departure - A spaceship assemblies in Earth orbit is ready to depart to Phobos, one of Mars's satellites. This ship consists of several fuel tanks and an Orion-type space capsule with three astronauts on board. No landing gear is required because the mass of Phobos is so low that this satellite can be approached by astronauts in extravehicular exit. A complete rocket system for delivering a crew of three to Mars' moon Phobos and returning them to the Earth. The vast bulk of the rocket is propellant divided into stages that are each released in turn as the mission progresses. On the far right are the crew accomodations and an attached Orion class command module. No dedicated lander is required as Phobos' mass is so low that it could be easily approached by the command module and explored by suited astrogeologists in Manned Maneuvering Units (MMUS) / Bridgeman Images
