Born, John Flamsteed, first astronomer royal of England

John Flamsteed (August 19, 1646 - December 31, 1719) was the first Astronomer Royal of England. Among other things, he accurately calculated the solar eclipses of 1666 and 1668. He also observed Uranus on December 23, 1690, without realizing it was an undiscovered planet, mistaking it for a star which he classified as 34 Tauri.

NASA GSF launched the Syncom 3 communication satellite, the first true zero-inclination geostationary satellite. It also carried the Star Flash experiment.

Syncom 3 was the first geostationary satellite. (The earlier geosynchronous Syncom 2 had an orbit inclined to the equator.) It was an experimental geosynchronous communications satellite placed over the equator at 180 degrees longitude in the Pacific Ocean (positioned in geosynchronous orbit at 64 deg W in 1964; 180 deg E in 1964; 25 deg W in 1965; 165 deg E in 1966-1969; as of 6 December 1974, it was at 6.08 deg W drifting at 0.188 deg W per day).

Syncom 3 provided live television coverage of the 1964 Olympic games in Tokyo, Japan and conducted various communications tests. Operations were turned over to the Department of Defense on 1 January 1965, Syncom 3 was to prove useful in the DoD's Vietnam communications.

1965
A spacecraft computer malfunction caused a countdown hold 10 minutes before the scheduled Gemini-Titan 5 launch. With the weather deteriorating rapidly (thunderstorms near Cape Kennedy), the mission was scrubbed, rescheduled to 21 August.

Gemini 5, carrying astronauts Gordon Cooper and Charles "Pete" Conrad was the third crewed Earth orbiting spacecraft of the Gemini series. Mercury veteran Cooper was the first person to travel on orbital missions twice. The flight was designed to last eight days, the length of time that it would take to fly a mission to the Moon, and to test rendezvous procedures. The major objectives of this mission were to demonstrate a long-duration crewed flight, evaluate the effects of long periods of weightlessness on the crew, and test rendezvous capabilities and maneuvers using a rendezvous evaluation pod. Secondary objectives included demonstration of all phases of guidance and control systems to support rendezvous and controlled reentry guidance, to evaluate the fuel cell power system and rendezvous radar, to test the capability of either pilot to maneuver the spacecraft in orbit to close proximity with another object, and to conduct 17 experiments. Gemini 5 doubled the manned space flight duration record to nearly eight days, thanks to new fuel cells that generated enough electricity to power longer missions.

Gemini 5 was launched from Complex 19 at Cape Kennedy, Florida, on 21 August 1965 at 8:59:59 AM EST (13:59:59.518 UT), and inserted into a 162.0 x 350.1 km Earth orbit at 9:05:55. The rendezvous evaluation pod (REP), a 34.5 kg optical and electronic duplicate of the Agena planned for use in later Gemini rendezvous missions was deployed two hours into the flight on the second revolution. About 36 minutes into the evaluation of the rendezvous system, the crew noticed the pressure in the oxygen supply tank of the fuel cell system was dropping. At some point earlier in the flight, the oxygen supply heater element had failed, and the pressure dropped from nominal pressure of 850 psia to a low of 65 psia 4 hours and 22 minutes into the flight. This was still above the 22.2 psia minimum but it was decided to cancel the REP exercise and power the spacecraft down. An analysis was carried out on the ground, and a powering up procedure was started on the seventh revolution. During the remainder of the mission, the flight plan was continuously scheduled in real time, pressure slowly rose in the fuel cells, and sufficient power was available at all times.

Four rendezvous radar tests were conducted during the mission, in the first in revolution 14, on the second day, the spacecraft rendezvous radar successfully tracked a transponder on the ground at Cape Kennedy. On the third day, a simulated rendezvous with a phantom Agena was conducted at full electrical load, in which the the Gemini maneuvered to a predetermined position in space. The simulation comprised four maneuvers: apogee adjust, phase adjust, plane change, and coelliptical maneuver, using the orbit attitude and maneuver system (OAMS). On day five, thruster number 7 became inoperative and maneuvering system operation became sluggish. Thruster number 8 failed the next day, and the system became increasingly erratic. Limited experimental and operational activities continued throughout the remainder of the mission. On the last flight day, Cooper and Conrad spoke to astronaut Scott Carpenter, who was 205 feet underwater in Sealab II.

Retrofire occurred at 7:27:42 AM EST on 29 August on revolution 120, one revolution early due to a threatening tropical storm near the landing area. The crew had to use the re-entry thrusters to orient the spacecraft because of the OAMS system failures. The retrofire and re-entry were conducted in darkness by the spacecraft computer. Splashdown occurred at 7:55:13 AM EST in the western Atlantic at 29.73 N, 69.75 W after a total mission time of 190:55:14. Splashdown was 169 km short of the target due to incorrect navigation coordinates transmitted to the spacecraft computer from the ground network: Someone had entered the rate of the Earth's rotation as 360 per 24 hours instead of 360.98 (sidereal day correction). Cooper's efforts compensated for what he recognized as an erroneous reading and brought the capsule down closer to the ship than they would otherwise have been. The crew arrived onboard the aircraft carrier USS Lake Champlain at 9:26 AM EST and the spacecraft was recovered at 11:50 AM EST.

All objectives were achieved except rendezvous with the REP and pilot tests associated with the rendezvous and the demonstration of controlled reentry to a predetermined landing point. Scientific studies included zodiacal light, synoptic terrain, synoptic weather photography, and a cloudtop spectrometer experiment. In addition, five medical and seven technological experiments were performed during the mission. One photography experiment was cancelled because of cancellation of the rendezvous maneuver. The mission demonstrated human ability to adapt to weightlessness over an extended period and then readapt to normal gravity and was considered successful.

With this flight, the US finally took the manned spaceflight endurance record from Russia, while demonstrating that the crew could survive in zero gravity for the length of time required for a Lunar mission. However, the astronauts found the mission incredibly boring, with the spacecraft just drifting to conserve fuel most of the time, and was "just about the hardest thing I've ever done" according to a hyperactive Pete Conrad who later lamented that he had not brought along a book. An accident with freeze dried shrimp also resulted in the cabin being filled with little pink subsatellites.

The Gemini program was designed as a bridge between the Mercury and Apollo programs, primarily to test equipment and mission procedures in Earth orbit and to train astronauts and ground crews for future Apollo missions. The general objectives of the program included: long duration flights in excess of of the requirements of a Lunar landing mission; rendezvous and docking of two vehicles in Earth orbit; the development of operational proficiency of both flight and ground crews; the conduct of experiments in space; extravehicular operations; active control of reentry flight path to achieve a precise landing point; and onboard orbital navigation. Each Gemini mission carried two astronauts into Earth orbit for periods ranging from 5 hours to 14 days. The program consisted of 10 crewed launches, 2 uncrewed launches, and 7 target vehicles.

The Gemini 5 capsule is now on display at the Lyndon B. Johnson Space Center, Houston, Texas.

NASA's STS 85 (Discovery 23, 86th Shuttle mission) landed after carrying a complement of payloads focused on Mission to Planet Earth objectives, and as preparations for the International Space Station assembly:

STS 85 was launched on time on 7 August 1997 after a smooth countdown carrying a complement of payloads in the cargo bay that focused on Mission to Planet Earth objectives, and as preparations for International Space Station assembly: the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2 (CRISTA-SPAS-02); the Japanese Manipulator Flight Development (MFD); the Technology Applications and Science-01 (TAS-1) and the International Extreme Ultraviolet Hitchhiker-02 (IEH-02).

This was the second flight of the CRISTA-SPAS payload. CRISTA-SPAS-02 also represented the fourth mission in a cooperative venture between the German Space Agency (DARA) and NASA. The payload included three telescopes and four spectrometers, deployed on flight day one, to gather data about Earth's middle atmosphere. After more than 200 hours of free flight, CRISTA-SPAS was retrieved on 16 August. The three CRISTA telescopes collected 38 full atmospheric profiles of the middle atmosphere. A total of 22 sounding rockets and 40 balloons were launched from the ground to provide correlating data during the mission. A complementary instrument, the Middle Atmosphere High Resolution Spectrograph Investigation (MAHRSI) also performed well. Data from STS-85 and first CRISTA-SPAS flight, STS-66 in 1994, was expected to yield new insight into the distribution of ozone in the Earth's atmosphere. Once science operations were complete, CRISTA-SPAS was used in simulation exercise to prepare for the first International Space Station (ISS) assembly flight, STS-88, with the payload being manipulated as if it were the Functional Cargo Block (FGB) that will be attached to ISS Node 1.

TAS-1 was a Hitchhiker payload carrying eight experiments designed to demonstrate faster, better, cheaper avionics and processes: Solar Constant Experiment (SOLCON), Infrared Spectral Imaging Radiometer (ISIR) and Shuttle Laster Altimeter (SLA), all part of NASA's Mission to Planet Earth program; and the Critical Viscosity of Xenon (CVX), Space Experiment Module (SEM); Two Phase Flow (TPF); Cryogenic Flight Experiment (CFE) and Stand Alone Acceleration Measurement Device and the Wide Band Stand Alone Acceleration Measurement Device (SAAMD/WBSAAMD). All the experiments were completed successfully.

MFD was designed to evaluate use of the Small Fine Arm that will be part of the future Japanese Experiment Module's Remote Manipulator System on the ISS. Despite some glitches, MFD completed a series of exercises by the crew on orbit as well as operators on the ground. Two unrelated Japanese experiments, Two-Phase Fluid Loop Experiment (TPFLEX) and Evaluation of Space Environment and Effects on Materials (ESEM), were mounted near the Small Fine Arm in the payload bay.

IEH-02 was flying a second time and consisted of four experiments, all of which performed well on-orbit: Solar Extreme Ultraviolet Hitchhiker-2 (SEH); Ultraviolet Spectrography Telescope for Astronomical Research (UVSTAR); Distribution and Automation Technology Advancement - Colorado Hitchhiker and Student Experiment of Solar Radiation (DATA-CHASER); and Shuttle Glow Experiment-5 and -6, all with common objective to investigate solar extreme ultraviolet (EUV) flux and EUV emissions of the Jupiter Io plasma torus system.

In-cabin payloads included: Bioreactor Demonstration System-3 (BDS-3), a cell biology research payload which has flown previously. On this flight, BDS was used for growing colon cancer cells to a larger size than can be achieved on Earth. Protein Crystal Growth - Single locker Thermal Enclosure System (PCG-STES); Midcourse Space Experiment (MSX); Shuttle Ionospheric Modification with Pulsed Local Exhaust (SIMPLEX); Southwest Ultraviolet Imaging System (SWUIS), used to observe the Hale-Bopp comet; two Get Away Special (GAS) payloads; Biological Research in Canisters-10 (BRIC-10), one in a series of flights; and the Solid Surface Combustion Experiment (SSCE).

The crew also worked with the Orbiter Space Vision System (OSVS), which will be used during ISS assembly. OSVS features a series of dots strategically placed on various payload and vehicle stuctures that permit precise alignment and pointing capability.

STS 85 ended 19 August 1997 when Discovery landed on Runway 33, Kennedy Space Center, Florida. Rollout distance: 8,792 feet (2,680 meters). Rollout time: One minute, eight seconds. Mission duration: 11 days, 20 hours, 26 minutes, 59 seconds. Discovery landed on revolution 190. The landing opportunity on 18 August was waved off due to the threat of ground fog in the local area.

The flight crew for STS 85 was: Curtis L. Brown, Jr., Mission Commander; Kent V. Rominger, Pilot; N. Jan Davis, Mission Specialist; Robert L. Curbeam, Jr., Mission Specialist; Stephen K. Robinson, Mission Specialist; Bjarni Tryggvason, (CSA) Payload Specialist.
