Gherman Titov became the first Soviet cosmonaut to exercise manual control of his Vostok 2 craft on August 6, 1961. The Soviet Union demonstrated 24-hour launch pad turnaround and the capability to launch two piloted spacecraft, Vostok 3 and Vostok 4, in essentially identical orbits, on August 11 and 12, 1962. The two spacecraft came within approximately 6.5 kilometers (4.0 mi) of one another, close enough for radio communication. Vostok 4 also set a record of nearly four days in space. Though the two craft's orbits were as nearly identical as possible given the accuracy of the launch rocket's guidance system, slight variations still existed which drew the two craft at first as close to each other as 6.5 kilometers (3.5 nautical miles), then as far apart as 2,850 kilometers (1,540 nautical miles). There were no maneuvering rockets on the Vostok to permit space rendezvous, required to keep two spacecraft a controlled distance apart.
What first person from the USSR controlled their own spacecraft?
A: Gherman Titov

At common law, in general, a myocardial infarction is a disease, but may sometimes be an injury. This can create coverage issues in administration of no-fault insurance schemes such as workers' compensation. In general, a heart attack is not covered; however, it may be a work-related injury if it results, for example, from unusual emotional stress or unusual exertion. In addition, in some jurisdictions, heart attacks suffered by persons in particular occupations such as police officers may be classified as line-of-duty injuries by statute or policy. In some countries or states, a person having suffered from an MI may be prevented from participating in activity that puts other people's lives at risk, for example driving a car or flying an airplane.
What is a myocardial infarction is always considered to be?
A: unanswerable

FETs are divided into two families: junction FET (JFET) and insulated gate FET (IGFET). The IGFET is more commonly known as a metaloxidesemiconductor FET (MOSFET), reflecting its original construction from layers of metal (the gate), oxide (the insulation), and semiconductor. Unlike IGFETs, the JFET gate forms a pn diode with the channel which lies between the source and drain. Functionally, this makes the n-channel JFET the solid-state equivalent of the vacuum tube triode which, similarly, forms a diode between its grid and cathode. Also, both devices operate in the depletion mode, they both have a high input impedance, and they both conduct current under the control of an input voltage.
How many layers of metal are in the gate of an IGFET?
A:
unanswerable
