Born, Paul A. M. Dirac, English physicist (quantum mechanics, Nobel 1933 with Schrodinger "for the discovery of new productive forms of atomic theory")
Paul Adrien Maurice Dirac, (8 August 1902 - 20 October 1984) was a British theoretical physicist and a founder of the field of quantum physics.
Dirac studied electrical engineering at the University of Bristol, completing his degree in 1921. After working briefly as an engineer, Dirac decided that his true calling lay in the mathematical sciences. He completed a degree in mathematics at Bristol in 1923 and then received a grant to conduct research at St. John's College, Cambridge, where he would remain for most of his career. At Cambridge he became interested in the general theory of relativity and in the nascent field of quantum physics, and worked under the supervision of Ralph Fowler.
In 1926 he developed a version of quantum mechanics that incorporated the previous work of Werner Heisenberg on "Matrix Mechanics" and of Erwin Schrodinger on "Wave Mechanics" into a single mathematical formalism that associates measurable quantities with operators acting on the Hilbert space of vectors that describe the state of a physical system. For this seminal work he was awarded a Ph.D. from Cambridge.
In 1928, building on Pauli's work on nonrelativistic spin systems, he derived the Dirac equation, a relativistic equation describing the electron. This work led Dirac to predict the existence of the positron, the electron's antiparticle, which he interpreted in terms of what came to be called the Dirac sea. The positron was subsequently observed by Carl Anderson in 1932. Dirac also contributed to explaining the origin of quantum spin as a relativistic phenomenon.

The USSR Salyut 5 research laboratory was de-orbited and destroyed during re-entry into the Earth's atmosphere.
Salyut 5, launched 22 June 1976, was the second successful flight of the USSR Almaz manned military space station. Structurally similar to Salyut 3, it had a total mass of approximately 18-19 tons. It had two solar panels laterally mounted on the center of the station, and a detachable recovery module, for the return of research data and materials. Tracking ships with Academician Sergei Korolev and Cosmonaut Yuri Gagarin were stationed in the Atlantic and Caribean to provide communications when out of tracking range of the USSR. Salyut 5 operated for 409 days, during which the crews of Soyuz 22 (7 July - 24 August 1976) and 24 (8 February 8 - 25 February 1977) visited the station. Soyuz 23 was also to have docked (15 October 1976), but its long distance rendezvous system failed. Soyuz 25 was planned, but the mission would have been incomplete due to low orientation fuel on Salyut 5, so it was cancelled.
During the flight of Salyut 5 a "parallel crew" worked in a duplicate station on the ground. They conducted the same operations in support of over 300 astrophysical, geophysical, technological, and medical/biological experiments. Astrophysics studies included an infrared telescope-spectrometer in the 2-15 micrometer range, which also obtained solar spectra. Earth resources studies were conducted as well as Kristall, Potok, Diffuziya, Sfera, and Reatsiya technology experiments. Presumably Salyut 5 was equipped with a SAR side-looking radar for reconnaissance of land and sea targets even through cloud cover.
The film capsule was ejected 22 February 1977, the station was deorbited on 8 August 1977. In addition to the human crew, two Russian tortoises (Testudo horsfieldi) and Zebrafish (Danio rerio) were flown.
The results of the Salyut 3 and 5 flights showed that manned reconnaissance was not worth the expense. There was minimal time to operate the equipment after the crew took the necessary time for maintenance of station housekeeping and environmental control systems. The experiments themselves showed good results, especially the value of reconnaissance of the same location in many different spectral bands and parts of the electromagnetic spectrum.

Pioneer 13, the Pioneer Venus Multiprobe mission, was launched 8 August 1978. On this mission, four instrumented atmospheric entry probes were carried by the spacecraft bus to the vicinity of Venus and released for descent through the atmosphere to the planetary surface. Two small probes entered on the night side, and one small probe and the large probe entered on the day side of the planet. During the 123 day trip to Venus, the large probe was released 16 November 1978, and the three small probes on 20 November. All four probes entered the Venusian atmosphere on 9 December, followed by the bus. The large probe took 1.5 hours to descend through the atmosphere, while the three smaller probes reached the surface of the planet 75 minutes after entry. The bus portion of the spacecraft was targeted to enter the Venusian atmosphere at a shallow entry angle and transmit data to Earth until it was destroyed by the heat of atmospheric friction during its descent. Investigators emphasized the study of the structure and composition of the atmosphere down to the surface, the nature and composition of the clouds, the radiation field and energy exchange in the lower atmosphere, and local information on the atmospheric circulation pattern. Simultaneous measurements by the probes and the Pioneer Venus Orbiter permitted relating specific local measurements to the general state of the planet and its environment as observed from orbit. The probes stopped transmitting temperature data about 15 km above the surface of Venus, but two probes survived on the surface and transmitted other data for a matter of seconds to minutes. The bus ceased transmitting data at an altitude of about 165 km.

NASA's STS 46 (Atlantis 12, Shuttle 49) ended after carrying the TSS-1 Tethered Satellite System to space, and deploying EURECA, the European Retrievable Carrier.
STS 46 was launched 31 July 1992, its liftoff delayed 48 seconds at T-5 minutes to allow the orbiter computers to verify the orbiter auxiliary power units were ready to start.
The primary objectives of STS 46 were deployment of the European Space Agency's European Retrievable Carrier (EURECA), and operation of the joint NASA/Italian Space Agency Tethered Satellite System (TSS). The mission was extended one day to complete the science objectives. EURECA was deployed one day later than scheduled because of a problem with its data handling system. After deployment, the spacecraft's thrusters were fired to boost EURECA to its planned operating altitude of about 310 statute miles (499 kilometers). However, thruster firing was initially cut to six minutes instead of the planned 24 minutes because of unexpected attitude data from EURECA. The problem was resolved, and EURECA was boosted to its operational orbit on the sixth day of the mission. The EURECA payload would later be retrieved by STS 57 in 1993.
The TSS deployment was also delayed one day because of EURECA. During TSS deployment, the satellite reached a maximum distance of only 840 feet (256 meters) from the orbiter instead of the planned 12.5 miles (20 kilometers) because of a jammed tether line. After numerous attempts over several days to free the tether, TSS operations were curtailed, and the satellite was stowed for return to Earth.
Secondary payloads were: Evaluation of Oxygen Integration with Materials/Thermal Management Processes (EOIM-III/TEMP 2A-3); Consortium for Materials Development in Space Complex Autonomous Payload (CONCAP II and CONCAP III); IMAX Cargo Bay Camera (ICBC); Limited Duration Space Environment Candidate Materials Exposure (LDCE); Air Force Maui Optical Site (AMOS); Pituitary Growth Hormone Cell Function (PHCF); and Ultraviolet Plume Instrument (UVPI).
STS 46 ended 8 August 1992 when Atlantis landed on revolution 127 on Runway 33, Kennedy Space Center, Florida. Rollout distance: 10,860 feet (3,310 meters). Rollout time: 66 seconds. Launch weight: 256,031 pounds. Landing weight: 208,806 pounds. Orbit altitude: 230 nautical miles. Orbit inclination: 28.45 degrees. Mission duration: seven days, 23 hours, 15 minutes, three seconds. Miles traveled: 3.3 million. STS 46 was the last flight of OV-104 before its scheduled checkout and modification period, which was later extended to include modifications for docking with the Russian Mir space station; OV-104 was shipped to the Rockwell plant in California in October.
The flight crew for STS 46 was: Loren J. Shriver, Commander; Andrew M. Allen, Pilot; Jeffrey A. Hoffman, Mission Specialist 1; Franklin R. Chang-Diaz, Mission Specialist 2; Claude Nicollier, Mission Specialist 3; Marsha S. Ivins, Mission Specialist 4; Franco Malerba, Payload Specialist 1

NASA launched the ill-fated Genesis solar wind sample return mission.

Source: NSSDCA Master Catalog
The primary objective of the Genesis mission was to collect samples of solar wind particles and return them to Earth for detailed analysis. The science objectives were to obtain precise measurements of solar isotopic and elemental abundances and provide a reservoir of solar matter for future scientific analysis. Specifically, the primary scientific objectives were to obtain precise measurements of isotope ratios of oxygen, nitrogen, and solar wind isotopic fractionation. Study of these samples would allow testing of theories of solar system formation and evolution and early nebular composition. A total sample mass of roughly 10 to 20 micrograms was expected.
The Genesis spacecraft had a launch mass of 636 kg, including 142 kg of fuel, and consisted of a 2.3 meter long, 2 meter wide spacecraft deck with two fixed solar panel wings with a total span of 7.9 meters, and a sample return capsule mounted on top of the deck. The spacecraft was spin stabilized at one revolution every 37.5 seconds. Propulsion was provided by a hydrazine monopropellant thruster using a helium pressurant. Communication was in the S-band via a fixed antenna. The solar panels provided a maximum of 254 Watts of power to a nickle-hydrogen storage battery. Temperatures were maintained by heaters and passive thermal control. The spacecraft was also equipped with ion and electron electrostatic monitors to determine which solar wind regime was being encountered, and to help set the appropriate collector voltage. Spacecraft subsystems and monitors were mounted beneath the sample return capsule.
The sample return capsule was disc shaped with a blunt conical top and bottom, 1.5 meters in diameter and 1.31 meters high, with a total mass of about 225 kg. It contained a 97.3 cm diameter science cannister which held a concentrator and three collector arrays. The collector arrays were flat discs made of ultra-pure silicon, silicon carbide, germanium, sapphire, chemically deposited diamond, gold, aluminum, and metallic glass wafers which were exposed to the solar wind. Isotopes of helium, oxygen, nitrogen, neon, radon, and other elements were implanted in the top 100 nm of these materials. The concentrator was an electrostatic mirror which concentrated elements up to neon by a factor of approximately 20. Each collector array was to be deployed for a different solar wind regime.
Genesis was launched successfully at 16:13:40.324 UT on 8 August 2001 on a Delta 7326 (a Delta II Lite launch vehicle with three strap-on solid rocket boosters and a Star 37FM third stage). The first burn of the Delta second stage put Genesis in a 185 x 197 km x 28.5 deg parking orbit at 1624 GMT. At 1712 GMT a second burn raised the orbit to 182 x 3811 km, and at 1713 GMT the third stage fired to put Genesis on its trajectory towards the Sun-Earth L1 Lagrangian libration point, 0.01 AU from Earth, with a nominal apogee of around 1.2 million km, a three month journey. The L1 point is beyond the influences of the geomagnetic field and its trapped particles. Genesis reached the L1 point on 16 November 2001 and fired its hydrazine thrusters for 268 seconds to insert itself into a halo orbit at 19:03 UT (2:03 PM EST). A malfunctioning thermal radiator caused some concern for the health of the sample return capsule's critical battery, which was overheating, but Genesis began collecting solar wind samples on schedule. On 3 December 2001 it opened its collector arrays and began gathering samples of solar wind particles. It completed 5 halo orbits over 30 months collecting samples. In April 2004, it ended sample collection and shut the door to the sample collection cannister.
The samples were stowed and sealed in the contamination-tight canister within the Sample Return Capsule and returned to Earth over a five month period, flying past the Earth and returning in order to be positioned for daylight entry. On 8 September 2004, the Genesis space probe became the first spacecraft to return from beyond Lunar orbit to the Earth's surface. The sample return capsule was released from the main spacecraft bus at about 12:00 UT, 66,000 km above the Earth, and successfully re-entered the Earth's atmosphere at 15:52:47 UT (11:53 AM EDT, 9:53 AM local MDT) over Oregon at 11 km/s, and should have deployed a drogue parachute 2 minutes 7 seconds after entry at 33 km altitude, but a wiring error resulted in the drogue parachute release mortar failing to fire. The parachute never deployed, and the capsule crashed in the desert in the Dugway Proving Ground at 40 07 40 N 113 30 29 W at a speed of 86 m/s (311 km/hr, 193 mph), severely damaging the capsule. The science cannister was removed to a clean room and the sample collection fragments were shipped to Johnson Space Center. The cause of the parachute failure was believed to be incorrectly installed accelerometers which were to deploy the parachutes. The science team was confident that most of the planned science could be recovered from the salvaged sample collectors.
The spacecraft bus looped around Earth after the capsule was released and headed back out towards the L1 point.
The original plan for re-entry was as follows: Six minutes after drogue chute deployment, the main parafoil was to deploy at an altitude of 6 km over the USAF Utah Test and Training Range, where it would be aerocaptured by one of two specially equipped helicopters at an altitude of about 2.5 km. The spacecraft had the capability of going into a parking orbit if the weather at the capture site was unsuitable. The capsule was taken to a clean room at the US Army Dugway Proving Ground, transported to Johnson Space Center for contamination control and curation, and distributed to selected Advanced Analytical Instrument Facilities for analysis.
There was some concern that the sample return capsule battery would fail, jeopardizing the re-entry. The battery was overheating in space, but ground tests showed that the battery should have been unaffected by the amount of heating it had endured, and should have operated to deploy the parachute on reentry.
