90-538: The vessel was used in the Five Deeps Expedition , becoming the first crewed submersible to reach the deepest point in all five oceans. Over 21 people have visited Challenger Deep , the deepest area on Earth, in the DSV. Limiting Factor was used to identify the wrecks of the destroyers USS  Johnston at a depth of 6,469 m (21,224 ft), and USS  Samuel B. Roberts at 6,865 m (22,523 ft), in

180-476: A flight stick , is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Also known as the control column , it is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick . It has various switches to control functions of the aircraft controlled by the Pilot and First Officer of

270-487: A proa . The long horizontal axis is 4.6 m (15 ft), while the short horizontal axis extent is only 1.9 m (6 ft 3 in). The height is 3.7 m (12 ft). The vessel is operated by a pilot, and has seating for an observer The pressure hull is a 1,500 mm (59 in) inside diameter by 90 mm (3.5 in) thick grade 5 titanium ( Ti-6Al-4V ELI) alloy sphere machined to within 99.933% of spherical (for enhanced buckling stability). The sphere

360-527: A spoon worm at nearly 23,000 ft (7,000 m), the deepest level at which the species had ever been encountered. On 7 May 2019, Vescovo and Jamieson, in Limiting Factor , made the first human-occupied deep submersible dive to the bottom of the Sirena Deep, the third deepest point in the ocean, about 128 mi (206 km) northeast of Challenger Deep. They spent 176 minutes at the bottom, and among

450-418: A 3D programmable controller, which was integrated into computer games to experience flight simulations. This line adapted several aspects of NASA's RHC (Rotational Hand Controller), which is used for landing and navigation methods. In 1997 the first gaming joystick with force feedback ( haptics ) was manufactured by CH Products under license from technology creator, Immersion Corporation . The product, called

540-569: A Kongsberg EM124 multibeam echo-sounder and three robot landers. Inkfish plans to use the HES system to continue exploring the ocean depths, led by Prof Alan Jamieson of the University of Western Australia, who was chief scientist on most of Vescovo's expeditions. The DSV was renamed to Bakunawa and the support vessel to Dagon . In 2018, Victor Vescovo launched the Five Deeps Expedition, with

630-423: A console joypad, so licensed home arcade sticks for these games have been manufactured for home consoles and PCs. A hat switch is a control on some joysticks. It is also known as a POV (point of view) switch in electronic games, where it allows one to look around in one's virtual world, browse menus, etc. For example, many flight simulators use it to switch the player's views, while other games sometimes use it as

720-454: A control method. In 1996, a scientific study established that both chimpanzees and rhesus monkeys could be taught to move a pointer on a screen by using a joystick. Both have consistently managed to demonstrate "conceptual knowledge" of the task required of them during trials, although rhesus monkeys were notably slower to do so. In 2021, another pair of researchers investigated the level of intelligence in domestic pigs by designing

810-626: A depth of 5,550 m (18,210 ft) at the bottom of the Molloy Deep in the Arctic Ocean . He was the first human to reach this location. In 2019, Vescovo escorted Titanic -historian Parks Stephenson to the wreck of the RMS Titanic for the first revisit of the wreck in 15 years. Findings included continued extensive corrosion and bacterial growth on iron and steel surfaces. In February 2020, Vescovo piloted his deep diving submersible twice to

900-512: A depth of 6,456 metres (21,181 ft) in the Philippine Sea ; at the time of identification this was the deepest shipwreck ever surveyed. The Johnston was sunk during the Battle off Samar (1944) in one of the most lopsided naval battles in history. In 2022 a submersible expedition piloted by Vescovo located the wreck of destroyer escort USS  Samuel B. Roberts  (DE-413) (also sunk in

1080-459: A dive on the wreck of the Minerve in the Limiting Factor . On the first dive, 1 February 2020, Vescovo dived with retired French Rear Admiral Jean-Louis Barbier, to gather new information on the cause of the loss. On the second dive, 2 February, Vescovo piloted while Hervé Fauve, the son of the submarine's commanding officer, sat in the second seat. At the bottom they placed a granite memorial plaque on

1170-535: A foot-operated rudder bar for the yaw control surface on the tail. The name joystick is thought to originate with early 20th century French pilot Robert Esnault-Pelterie . There are also competing claims on behalf of fellow pilots Robert Loraine , James Henry Joyce , and A. E. George . Loraine is cited by the Oxford English Dictionary for using the term "joystick" in his diary in 1909 when he went to Pau to learn to fly at Blériot's school. George

1260-466: A gaming joystick but which is used to control flight, replacing the traditional yoke . The sidestick saves weight, improves movement and visibility in the cockpit, and may be safer in an accident than the yoke. Ralph H. Baer , inventor of the Magnavox Odyssey console, released in 1972, created the first video game joysticks in 1967. They were able to control the horizontal and vertical position of

1350-427: A joystick which could be controlled with their snout. Unlike the chimpanzees or the rhesus monkeys, none of the four pigs was able to fully meet the 1996's test criteria for " motoric or conceptual acquisition" of the task, but they still performed "significantly above chance". Notably, the pigs experienced additional difficulties in comparison to the primates, as they were all far-sighted and so may have struggled with

1440-416: A lot of copies of Descent. It was around that time [when] the more modern FPS with mouse and keyboard came out, as opposed to just keyboard like Wolfenstein [3D] or something.". Since the late 1990s, analog sticks (or thumbsticks , due to their being controlled by one's thumbs) have become standard on controllers for video game consoles, popularized by Nintendo 's Nintendo 64 controller , and have

1530-428: A producer at Volition Inc., he stated that FreeSpace 2 ' s poor sales could have been due to joysticks' being sold poorly because they were "going out of fashion" because more modern first-person shooters, such as Quake , were "very much about the mouse and [the] keyboard". He went further on to state "Before that, when we did Descent for example, it was perfectly common for people to have joysticks – we sold

1620-547: A relatively light flotilla of destroyers , destroyer escorts, and escort carriers called "Taffy 3" which was inadvertently left to fend off a fleet of heavily armed Japanese battleships , cruisers , and destroyers off the island of Samar during the Battle off Samar, one of the engagements making up the larger Battle of Leyte Gulf of October 1944. Steaming through incoming shells , Samuel B. Roberts scored one torpedo hit and several shell hits on larger enemy warships before she

1710-506: A second time on May 1, he became the first person to dive the Challenger Deep twice, finding "at least three new species of marine animals" and "some sort of plastic waste". Among the underwater creatures Vescovo encountered were a snailfish at 26,250 ft (8,000 m) and a spoon worm at nearly 23,000 ft (7,000 m), the deepest level at which the species had ever been encountered. On May 7, 2019, Vescovo and Jamieson made

1980-506: A substitute for the D-pad . Computer gamepads with both an analogue stick and a D-pad usually assign POV switch scancodes to the latter. The term hat switch is a shortening of the term "coolie hat switch," named for the similar looking headgear . In a real aircraft, the hat switch may control things like aileron or elevator trim. Apart from buttons, wheels and dials as well as touchscreens also miniature joysticks have been established for

2070-423: A true analog flight stick, used for movement. The joystick could register movement in any direction as well as measure the degree of push, which could move the player character at different speeds depending on how far the joystick was pushed in a certain direction. A variation of the joystick is the rotary joystick. It is a type of joystick-knob hybrid, where the joystick can be moved in various direction while at

2160-486: Is a positional gun , which works differently from a light gun . Instead of using light sensors, a positional gun is essentially an analog joystick mounted in a fixed location that records the position of the gun to determine where the player is aiming on the screen. It is often used for arcade gun games , with early examples including Sega 's Sea Devil in 1972; Taito 's Attack in 1976; Cross Fire in 1977; and Nintendo 's Battle Shark in 1978. During

2250-639: Is a digital controller with a single fire button. The Atari joystick port was for many years the de facto standard digital joystick specification. Joysticks were commonly used as controllers in first and second generation game consoles , but they gave way to the familiar game pad with the Nintendo Entertainment System and Master System during the mid-1980s, though joysticks—especially arcade-style ones—were and are popular after-market add-ons for any console. In 1985, Sega's third-person arcade rail shooter game Space Harrier featured

2340-570: Is particularly applicable in maneuvering aircraft without a pilot." The Germans developed an electrical two-axis joystick around 1944. The device was used as part of the Germans' Funkgerät FuG 203 Kehl radio control transmitter system used in certain German bomber aircraft, used to guide both the rocket-boosted anti-ship missile Henschel Hs 293 , and the unpowered pioneering precision-guided munition Fritz-X , against maritime and other targets. Here,

2430-444: Is temperature and humidity controlled, and the life support system uses carbon dioxide scrubbers and oxygen replenishment. Emergency life support is rated for 96 hours. All routine maintenance can be done using standard tools. Emergency release systems are provided for the batteries, so they can be jettisoned if they fail dangerously, and for the thrusters and manipulator arm, in case they get snagged on an obstacle which could prevent

2520-531: Is the earliest known usage of the term, although he most certainly did not invent the device. The electrical two-axis joystick was invented by C. B. Mirick at the United States Naval Research Laboratory (NRL) and patented in 1926 (U.S. Patent no. 1,597,416)". NRL was actively developing remote controlled aircraft at the time and the joystick was possibly used to support this effort. In the awarded patent, Mirick writes: "My control system

2610-656: Is the sapient warship provided to the main character Jernau Morat Gurgeh for transport to the Empire of Azad to take part in a board game tournament. It is nominally demilitarised, but retains part of its main armament. After the sale of the submersible to the research group Inkfish in 2022, it was renamed Bakunawa after the Filipino mythological creature Bakunawa . The DSV and support vessel DSSV Pressure Drop were sold in 2022 for an undisclosed amount to Gabe Newell ’s Inkfish ocean-exploration research organisation . The sale included

2700-566: Is the second deepest point on the planet and the deepest in the Southern Hemisphere at 10,823 m (35,509 ft). In doing so, Vescovo had descended to the first, second, and third deepest points in the ocean. Unlike the Sunda and Mariana Trenches, no signs of human contamination were found in the deep, which was described by the expedition as "completely pristine". Vescovo completed the Five Deeps Expedition on 24 August 2019 when he reached

2790-628: Is the use of strain gauges to build force transducers from which the output is proportional to the force applied rather than physical deflection. Miniature force transducers are used as additional controls on joysticks for menu selection functions. Some larger manufacturers of joysticks are able to customize joystick handles and grips specific to the OEM needs while small regional manufacturers often concentrate on selling standard products at higher prices to smaller OEMs. Specialist joysticks, classed as an assistive technology pointing device , are used to replace

2880-428: Is unobstructed by structure or appendages, and illuminated by ten externally mounted high output LED lighting panels of 20,000 lumens each. The limited direct field of view through the ports is augmented by an array of four full ocean depth capable low-light cameras. Four high definition cameras are also provided to record missions. Maneuvering is by control joystick , touch screen and manual override. The cabin

2970-403: Is unusual in that it can travel on three primary axes, and in practice does a large amount of traveling vertically. If one uses the direction in which the occupants look out on the surroundings through physical windows to define the bow, it is wider than it is long. Alternatively it may be considered to have a bow at either end of the long axis, depending on the direction of motion at the time, like

Vescovo served 20 years in the U.S. Navy Reserve as an intelligence officer, retiring in 2013 as a Commander (O-5). In 2018, Vescovo launched the Five Deeps Expedition, whose objective was to dive to the deepest location in all five of the world's oceans by the end of September 2019. This expedition

3420-503: The Permobil (1963). During this time period NASA used joysticks as control devices as part of the Apollo missions. For example, the lunar lander test models were controlled with a joystick. In many modern airliners , for example all Airbus aircraft developed from the 1980s, the joystick has received a new lease on life for flight control in the form of the " side-stick ," a controller similar to

3510-651: The Philippine Trench , the deepest dives on wrecks. It has also been used for dives to the French submarine Minerve (S647) at about 2,350 m (7,710 ft) in the Mediterranean sea, and RMS  Titanic at about 3,800 m (12,500 ft) in the Atlantic. The submersible is based on a spherical titanium pressure hull for two occupants, seated side by side, which has three wide angle acrylic viewports in front of

3600-548: The computer mouse for people with fairly severe physical disabilities. Rather than controlling games, these joysticks control the pointer . They are often useful to people with athetoid conditions, such as cerebral palsy , who find them easier to grasp than a standard mouse. Miniature joysticks are available for people with conditions involving muscular weakness such as muscular dystrophy or motor neurone disease as well. They are also used on electric powered wheelchairs for control since they are simple and effective to use as

3690-536: The "Six degrees of freedom" 3D shooter Descent . VirPil Controls' MongoosT-50 joystick was designed to mimic the style of Russian aircraft (including the Sukhoi Su-35 and Sukhoi Su-57 ), unlike most flight joysticks. However, since the beginning of the 21st century, these types of games have waned in popularity and are now considered a "dead" genre, and with that, gaming joysticks have been reduced to niche products. In NowGamer 's interview with Jim Boone,

3780-507: The 1990s, joysticks such as the CH Products Flightstick, Gravis Phoenix , Microsoft SideWinder , Logitech WingMan, and Thrustmaster FCS were in demand with PC gamers. They were considered a prerequisite for flight simulators such as F-16 Fighting Falcon and LHX Attack Chopper . Joysticks became especially popular with the mainstream success of space flight simulator games like X-Wing and Wing Commander , as well as

3870-538: The Arctic Ocean. USS Johnston (DD-557) was a Fletcher -class destroyer built for the United States Navy during World War II . On 25 October 1944, while assigned as part of the escort to six escort carriers , Johnston , two other Fletcher -class destroyers, and four destroyer escorts were engaged by a large Imperial Japanese Navy flotilla. In what became known as the Battle off Samar , Johnston and

In June 2023, Vescovo lost his friend Hamish Harding , whom he had been to space and sea with, when Harding died while trying to view the wreck of the Titanic inside OceanGate's Titan submersible . On Twitter Vescovo stated: "This has been

4050-543: The Force FX joystick was followed by force feedback joysticks from Logitech , Thrustmaster , and others, also under license from Immersion. An arcade stick is a large-format controller for use with home consoles or computers. They use the stick-and-button configuration of some arcade cabinets , such as those with particular multi-button arrangements. For example, the six button layout of the arcade games Street Fighter II or Mortal Kombat cannot be comfortably emulated on

4140-721: The Sunda Trench was deeper and settling the debate about where the deepest point in the Indian Ocean is. On April 28, 2019, Vescovo descended nearly 11 km (6.8 mi) to the deepest place in the ocean – the Challenger Deep in the Pacific Ocean 's Mariana Trench . On his first descent, he piloted the DSV Limiting Factor to a depth of 10,928 m (35,853 ft), a world record by 16 m (52 ft). Diving for

4230-428: The ability to indicate the stick's displacement from its neutral position. This means that the software does not have to keep track of the position or estimate the speed at which the controls are moved. These devices usually use potentiometers to determine the position of the stick, though some newer models instead use a Hall effect sensor for greater reliability and reduced size. In 1997, ThrustMaster, Inc. introduced

4320-579: The bottom of the South Sandwich Trench , the deepest part of the Southern Ocean , becoming the first person and first vessel to reach that point. In preparation for this dive, the expedition used a Kongsberg EM124 multibeam sonar system for accurate mapping of the trench. On 16 April 2019, Vescovo piloted Limiting Factor to the bottom of the Sunda Trench south of Bali , Indonesia, reaching

4410-482: The bottom of the Challenger Deep. These included former astronaut and NOAA Administrator Kathryn Sullivan , the first woman to ultimate depth; Kelly Walsh, the son of Don Walsh (who with Jacques Piccard made the first dive into the Challenger Deep) to become the only father/son team to make this journey albeit 60 years apart; and Vanessa O'Brien , the first woman to both climb Mount Everest and also descend to

4500-570: The bottom of the seafloor (Vescovo was the first person). At the end of his 2022 dives, Vescovo had the unique record of fifteen total dives to Challenger Deep, including the record for the deepest dive in history on April 28, 2019. Vescovo flew to space onboard New Shepard , as part of the Blue Origin NS-21 mission in 2022.

The French Daphne -class diesel–electric submarine Minerve was lost with all hands in bad weather while returning to her home port of Toulon in January 1968. Minerve

5040-584: The efficient manual operation of cameras . In recent times, the employment of joysticks has become commonplace in many industrial and manufacturing applications, such as cranes, assembly lines, forestry equipment, mining trucks, and excavators. In fact, the use of such joysticks is in such high demand, that it has virtually replaced the traditional mechanical control lever in nearly all modern hydraulic control systems. Additionally, most unmanned aerial vehicles (UAVs) and submersible remotely operated vehicles (ROVs) require at least one joystick to control either

5130-546: The first human-occupied deep submersible dive to the bottom of the Sirena Deep , the third deepest point in the ocean lying about 128 miles northeast from Challenger Deep. The time they spent there was 176 minutes; among the samples they retrieved was a piece of mantle rock from the western slope of the Mariana Trench. On June 10, 2019, Vescovo reached the bottom of the Horizon Deep in the Tonga Trench , confirming that it

5670-731: The flight. Joysticks are often used to control video games, and usually have push-buttons whose state can be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick . Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers . Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones . Joysticks originated as controls for aircraft ailerons and elevators , and are first known to have been used as such on Louis Bleriot 's Bleriot VIII aircraft of 1908, in combination with

5760-531: The joystick of the Kehl transmitter was used by an operator to steer the missile towards its target. This joystick had on-off switches rather than analogue sensors. Both the Hs 293 and Fritz-X used FuG 230 Straßburg radio receivers in them to send the Kehl's control signals to the ordnance's control surfaces. A comparable joystick unit was used for the contemporary American Azon steerable munition, strictly to laterally steer

5850-416: The maximum depth of the ocean of Earth. Test pressure of 14,000 msw (46,000 fsw, 1,400 bar, 20,000 psi) provides a safety margin. The vessel has been certified to a preliminary maximum diving depth of 10,925 ± 6.5 m (35,843 ± 21 ft) by DNV , based on data from the deepest dive. The vessel is commercially rated for repeated dives to full ocean depth. The vessel

5940-484: The missile. In the 1960s the use of joysticks became widespread in radio-controlled model aircraft systems such as the Kwik Fly produced by Phill Kraft (1964). The now-defunct Kraft Systems firm eventually became an important OEM supplier of joysticks to the computer industry and other users. The first use of joysticks outside the radio-controlled aircraft industry may have been in the control of powered wheelchairs, such as

After engaging several Japanese capital ships and a destroyer squadron, Johnston was sunk by gunfire, with 187 dead. The wreck was discovered on 30 October 2019 but was not properly identified until March 2021. Lying more than 20,000 ft (3.8 mi; 6,100 m) below the surface of the ocean, it

6390-418: The other for changing the shooting direction. In North America, it was released by Midway under the title Gun Fight . In 1976, Taito released Interceptor , an early first-person combat flight simulator that involved piloting a jet fighter , using an eight-way joystick to aim with a crosshair and shoot at enemy aircraft. The Atari CX40 joystick , developed for the 1977 Atari Video Computer System ,

6480-562: The outer hull for propulsion and maneuvering, as can be seen in the photographs. These thrusters provide three axis translational motion and two axis (yaw and roll) rotation. The vessel is commercially certified for unlimited full ocean depth operations by DNV GL . The Limiting Factor normally operates from a dedicated support vessel, DSSV  Pressure Drop , but can also be operated from other suitably equipped vessels. The designed operational maximum dive depth of 11,000 m (36,000 ft) represents approximate full ocean depth –

6570-493: The same time being able to rotate the joystick. It is mainly used in arcade shoot 'em up games, to control both the player's eight-directional movement and the gun's 360-degree direction. It was introduced by SNK , initially with the tank shooter TNK III (1985) before it was popularized by the run and gun video game Ikari Warriors (1986). SNK later used rotary joystick controls in arcade games such as Guerrilla War (1987). A distinct variation of an analog joystick

6660-518: The samples they retrieved was a piece of mantle rock from the western slope of the Mariana Trench. On 10 June 2019, Vescovo piloted Limiting Factor to the bottom of the Horizon Deep in the Tonga Trench , confirming that it is the second deepest point of the World ocean and the deepest in the Southern Hemisphere at 10,823 m (35,509 ft). In doing so, Vescovo and Limiting Factor had descended to

6750-533: The scanning of the Diamantina Fracture Zone using multibeam sonar, confirming that the Sunda Trench was deeper and settling the debate about where the deepest point in the Indian Ocean is. On 28 April 2019, Vescovo descended nearly 11 km (7 mi) in Limiting Factor to the deepest place in the World – the Challenger Deep in the Pacific Ocean's Mariana Trench . On his first descent, he piloted

6840-484: The screen; when a plane is hit, an explosion is animated on screen along with an explosion sound. In 1970, the game was released in North America as S.A.M.I. by Midway Games . Taito released a four-way joystick as part of their arcade racing video game Astro Race in 1973, while their 1975 multidirectional shooter Western Gun introduced dual-stick controls with one eight-way joystick for movement and

6930-412: The sea floor bow first and with enough force to cause some buckling, and observed that the ship's stern had separated from the rest of the hull by about 5 m (16 ft). They reported that they had found evidence of damage to the ship inflicted by a Japanese battleship shell , including the vessel's fallen mast . The wreck lies at a depth of 6,865 m (22,523 ft; 4.266 mi), making it

7020-431: The search ship Seabed Constructor . The wreck was found at a depth of 2,350 m (7,710 ft), broken into three main pieces scattered over 300 m (980 ft) along the seabed. Although Minerve ' s sail was damaged, it was possible to positively identify the wreckage. as the letters "MINE" and "S" (from Minerve and S647, respectively) were still readable on the hull. In December 2019, Vescovo proposed

7110-536: The vehicle, the on-board cameras, sensors and/or manipulators. Due to the highly hands-on, rough nature of such applications, the industrial joystick tends to be more robust than the typical video-game controller, and able to function over a high cycle life. This led to the development and employment of Hall effect sensing to such applications in the 1980s as a means of contactless sensing. Several companies produce joysticks for industrial applications using Hall effect technology. Another technology used in joystick design

7200-519: The vessel from surfacing. Launch and recovery from DSSV Pressure Drop is by a hydraulic luffing (tilting) A-frame over the transom. The vessel is stowed on deck in a cradle. The naming of these vessels is a large tip of the hat to, and with no small amount of admiration for, Iain M Banks’ brilliant "Culture" science fiction series. In Iain M. Banks' novel The Player of Games , the General Offensive Unit (demilitarised) Limiting Factor

7290-597: The wreck of the French submarine Minerve in the Mediterranean Sea. The retired French Rear Admiral Jean-Louis Barbier investigated the wreck of the Minerve on the first dive. On the second dive, Vescovo was accompanied by Hervé Fauve, the son of the captain of the sunken submarine. They placed a commemorative plaque at the wreck. In 2021, Vescovo identified and surveyed the wreck of the USS ; Johnston  (DD-557) at

7380-420: The wreck, but additional debris was observed lying deeper than the ship's ROV could go. On 31 March 2021, the Limiting Factor piloted by Victor Vescovo, surveyed and photographed the deeper wreckage and definitively identified it as Johnston . The wreck lies upright and is well preserved at a depth of 21,180 ft (4.011 mi; 6,460 m). Until Samuel B. Roberts was discovered on 22 June 2022, Johnston

7470-563: Was a pioneer aviator who with his colleague Jobling built and flew a biplane at Newcastle in England in 1910. The George and Jobling aircraft control column is in the collection of the Discovery Museum in Newcastle upon Tyne, England. Joysticks were present in early planes, though their mechanical origins are uncertain. The coining of the term "joystick" may actually be credited to Loraine, as his

7560-615: Was built as two forged titanium domes that interlock with o-ring seals. The structure is certified for repeated dives to full ocean depth. The hydrodynamic fairing of the outer surface shell is non-structural and removable for access to equipment. The vessel is operated from a dual 24 V battery power supply and emergency supply, which can be jettisoned in an emergency. The main battery stores 65 kW·h. There are 4 × 5.5 kW (7.4 hp) horizontal propulsion thrusters (main thrusters), 4 × 5.5 kW vertical thrusters, and 2 × 5.5 kW maneuvering thrusters, mounted in two clusters at

7650-435: Was filmed in the documentary television series Expedition Deep Ocean . This objective was achieved one month ahead of schedule, and the expedition's team carried out biological samplings and depth confirmations at each location. Besides the deepest points of the five world oceans, the expedition also made dives in the Horizon Deep and the Sirena Deep , and mapped the Diamantina Fracture Zone . In December 2018, he became

7740-517: Was one of four submarines lost to unknown causes in 1968 along with the Soviet submarine  K-129 , the American USS ; Scorpion , and Israeli submarine INS  Dakar . The French government started a new search for Minerve on 4 July 2019 in deep waters about 45 km (28 mi) south of Toulon. The location of the wreck was found on 21 July 2019 by the company Ocean Infinity using

7830-516: Was recognized by Guinness World Records as the person who has covered the greatest vertical distance without leaving Earth's surface. As part of achieving the Explorers Grand Slam (Last Degree), Vescovo climbed Mount Everest (8,848 metres (29,029 ft)) on 24 May 2010, Earth's highest point. Almost nine years later he dove to the bottom of the Challenger Deep in the Mariana Trench (−10,924 metres (−35,840 ft)), Earth's lowest point, in

7920-468: Was sunk. As of June 2022, it is the deepest shipwreck discovered. An exploration team led by Victor Vescovo and made up of personnel of Caladan Oceanic and EYOS Expeditions discovered the wreck of Samuel B. Roberts in June 2022. The team found, identified, and surveyed the wreck during a series of six dives from 17 to 24 June 2022. The team found that the wreck reached the seabed in one piece, although it hit

8010-568: Was the deepest identified shipwreck in the world. USS Samuel B. Roberts (DE-413) was a destroyer escort of the United States Navy that served in World War II and was sunk in the Battle off Samar, in which a small force of U.S. warships prevented a superior Imperial Japanese Navy force from attacking the amphibious invasion fleet off the Philippine island of Leyte . The ship was part of

8100-469: Was the deepest shipwreck ever surveyed until the discovery of USS  Samuel B. Roberts on 22 June 2022. On 30 October 2019, the Petrel , a research vessel belonging to Vulcan Inc. , discovered the remains of what was believed to be Johnston near the bottom of the Philippine Trench . The remains consisted of a deck gun, a propeller shaft, and some miscellaneous debris that could not be used to identify
