Comet T-AK-269
A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elli ...

Amphibious Assault Ship
An amphibious assault ship is a type of warship employed to land and support ground forces on enemy territory during an armed conflict. The design evolved from aircraft carriers converted for use as helicopter carriers (which, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern designs support amphibious landing craft, with most designs including a well deck. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft and have a secondary role as aircraft carriers. The role of the amphibious assault ship is fundamentally different from that of a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the sea-control role, embarking aircraft like Harrier or the new F-35B variant of the Lightning II fighters for combat air patrol and ...

Roll-on/roll-off
Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, Trailer (vehicle), trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane (machine), crane to load and unload cargo. RORO vessels have either built-in or shore-based Linkspan, ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for large seagoing vessels. The ramps and doors may be located in the stern, Bow (ship), bow, or sides, or any combination thereof. Description Types of RORO vessels include ferry, ferries, cruiseferry, cruiseferries, cargo ships, barges, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suisun Bay
Suisun Bay ( ; Wintun for "where the west wind blows") is a shallow tidal estuary (a northeastern extension of the San Francisco Bay) in Northern California. It lies at the confluence of the Sacramento River and San Joaquin River, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta. To the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. Grizzly Bay forms a northern extension of Suisun Bay. Suisun Bay is between Contra Costa County to the south and Solano County to the north. The bay was named in 1811 after the Suisunes, a Patwin tribe of Wintun people. The Central Pacific Railroad built a train ferry that operated between Benicia and Port Costa, California, from 1879 to 1930. The ferry boats ''Solano'' and ''Contra Costa'' were removed from service when the nearby Martinez railroad bridge was completed in 1930. From 1913 until 1954 the Sacramento Nort ...

Iraqi Conflict (2003–present)
The Iraqi conflict is a series of violent events that began with the 2003 American-led invasion of Iraq and deposition of Iraqi president Saddam Hussein, followed by a series of conflicts including the protracted Iraq War (2003–2011), the Iraqi insurgency (2011–2013), the War in Iraq (2013–2017), and most recently, the small-scale Islamic State insurgency in 4 provinces located in Northern Iraq since 2017.
