Viking was the first attempt by the United States to study Mars close-up.

Viking 1 was launched on August 20, 1975, and Viking 2, was launched on September 9, 1975. Both probes had the same structure: An orbiter, which would map Mars photographically and via radar from low orbit, and a lander.

The Viking Lander was released from the orbiter encased in a heat shield. Once it got low enough, the heat shields were released and a parachute deployed. As the lander neared the surface, the parachute was released and retrorockets fired to bring the lander down to a soft landing.

The Viking Landers were powered by small nuclear reactors, containing plutonium-238.

Each lander had a UHF antenna that provided a one-way uplink to the orbiter using a 30 watt radio. But they also had a 20-watt S-band transmitter and an omnidirectional low-gain S-band antenna, so they could continue functioning even if the orbiters did not.

Data was stored on a 40-Mbit tape recorder. The simple computer had a 6000-word command word memory.

The Landers studied the biology, chemical composition, meteorology, seismology, magnetic properties, appearance, and physical properties of Mars. For photographs of the Martian surface, each lander carried two 360-degree cameras, a seismometer, and magnifying mirror. A soil sampler arm with collector head, temperature sensor, and magnet extended from one side. A meteorology boom (with temperature, wind direction, and wind velocity sensors) extended from one of the lander legs. An interior compartment had the biology testing chamber, a gas chromatograph mass spectrometer, and an X-ray fluorescence spectrometer.

The Viking 2 lander ceased to function on April 11, 1980 — 3 years, 7 months, and 8 days after landing. The failure was because its batteries failed to recharge.

The Viking 1 lander failed on November 13, 1982 — after 6 years, 3 months, and 22 days. A computer programmer at the Jet Propulsion Laboratory accidentally told it to point its antenna at the soil. Communication was broken, and could not be re-established.

The original Insight had a conventional manual transmission. Starting with the 2001 model, a CVT variant of the Insight was available; the CVT is similar to that used in the Honda Civic Hybrid and the Honda Logo. A traditional transmission shifts between a fixed set of engine-to-wheel ratios; however, a CVT allows for an infinite set of ratios between its lowest gear and its highest. A feature shared by the two hybrids (and now appearing in others) is the ability to automatically turn off the engine when the vehicle is at a stop (and restart it upon movement). Since it is more powerful than most starters of conventional cars, the Insight’s electric motor can start the engine nearly instantaneously. The Integrated Motor Assist is run by an "Intelligent Power Unit (IPU)", a desktop computer-sized box. The Intelligent Power Unit, the Power control Unit, the Electronic Control Unit, the vehicle’s batteries, converter and a high-voltage inverter are all located under the cargo floor of the vehicle, behind the seats.

Quoting Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a successful, versatile fighter during the first half of World War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s "Flying Tigers" flew in China against the Japanese remain among the most popular airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the first American ace of World War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright built this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served until 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its last flight, March 6, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (2,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane over to the Smithsonian.

Transferred from the United States Air Force.

Quoting Smithsonian National Air and Space Museum | Vought F4U-1D Corsair :

By V-J Day, September 2, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design allowed ground clearance for the huge, three-bladed Hamilton Standard Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the largest and one of the most powerful engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.

Transferred from the United States Navy.

Manufacturer:
Vought Aircraft Company

Date:
1940

Country of Origin:
United States of America

Dimensions:
Overall: 460 x 1020cm, 4037kg, 1250cm (15ft 1 1/8in. x 33ft 5 9/16in., 8900lb., 41ft 1/8in.)

Details, quoting from Smithsonian National Air and Space Museum | Space Shuttle Enterprise:

Manufacturer:
Rockwell International Corporation

Country of Origin:
United States of America

Dimensions:
Overall: 57 ft. tall x 122 ft. long x 78 ft. wing span, 150,000 lb.
(1737.36 x 3718.57 x 2377.44cm, 68039.6kg)

Materials:
Aluminum airframe and body with some fiberglass features; payload bay doors are graphite epoxy composite; thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.

The first Space Shuttle orbiter, "Enterprise," is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for spaceflight. Although the airframe and flight control elements are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles because these features were not needed for atmospheric and ground tests. "Enterprise" was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long approach-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred "Enterprise" to the Smithsonian Institution’s National Air and Space Museum.

Automatic NERF EBF-25 Turret
Computer Batteries

Image by Randomskk
I rigged a NERF Vulcan/Havok Fire EBF-25 up so that its firing could be controlled by computer, then used the motion detecting software ‘motion’ for linux to have the gun fire when it detects the door opening.

The gun itself has three chained ammo belts, for a total of 74 shots, and a 12.6V lipo battery instead of the 9V D-cell battery pack it would use stock. The firing mechanism is an Arduino driving a servo connected to some pencils to pull the trigger, and there’s a Logitech C300 webcam on the gun to source video. The laptop itself also plays sound files from Portal turrets when motion is detected or stops being detected. Check out www.youtube.com/watch?v=wrWUhVeEcHk for video!
