American Interplanetary Society Rocket No. 2 successfully fired, attaining 250-foot altitude in 2 seconds, at Marine Park, Staten Island, N.Y. References: 17 .
Density research. Launched at 1815 local time. Reached 76.1 km.
Fired from AMR at 0052 hours EST to test impact accuracy. This shot may be considered as having hit the target. The impact was: .26 nm over and 0.4 nm to the left of the predicted point of impact. Accuracy of the MILS Network was approximated at plus-or-minus 0.25 nm. All primary and secondary missions were accomplished except for photographic recording of the second separation. This could not be accomplished because of the firing date. References: 439 .
An attempt was made to launch Mercury-Atlas 9 (MA-9), but difficulty developed in the fuel pump of the diesel engine used to pull the gantry away from the launch vehicle. This involved a delay of approximately 129 minutes after the countdown had reached T-60 minutes. After these repairs were effected, failure at the Bermuda tracking station of a computer converter, important in the orbital insertion decision, forced the mission to be canceled at T-13 minutes. At 6:00 p.m. e.d.t., Walter C. Williams reported that the Bermuda equipment had been repaired, and the mission was rescheduled for May 15, 1963. References: 483 .
The feasibility of docking a second Orbital Workshop to Skylab 1 had been under consideration. However, the practical problems that would be engendered by such an operation were formidable. They included such items as docking loads, docking control, flight attitude of tandem Skylabs, consumables, and in-orbit storage of Skylab 1.
First and only US space station to date. Project began life as Apollo Orbital Workshop - outfitting of an S-IVB stage with docking adapter with equipment launched by several subsequent S-1B launches. Curtailment of the Apollo moon landings meant that surplus Saturn V's were available, so the pre-equipped, five times heavier, and much more capable Skylab resulted.
An unexpected telemetry indication of meteoroid shield deployment and solar array wing 2 beam fairing separation was received 1 minute and 3 seconds after liftoff. However, all other systems of the OWS appeared normal, and the OWS was inserted into a near-circular Earth orbit of approximately 435 km altitude. The payload shroud was jettisoned, and the ATM with its solar array was deployed as planned during the first orbit. Deployment of the Workshop solar array and the meteoroid shield was not successful. In fact the xternal solar/meteoroid shield had ripped off 63 seconds into ascent, tearing away one solar panel wing and debris jamming the remaining panel. Without shield temperatures soared in station. Repairs by crews led to virtually all mission objectives being met.
Following the final manned phase of the Skylab mission, ground controllers performed some engineering tests of certain Skylab systems--tests that ground personnel were reluctant to do while men were aboard. Results from these tests helped to determine causes of failures during the mission and to obtain data on long term degradation of space systems.
Upon completion of the engineering tests, Skylab was positioned into a stable attitude and systems were shut down. It was expected that Skylab would remain in orbit eight to ten years. It was to have been visited by an early shuttle mission, reboosted into a higher orbit, and used by space shuttle crews. But delays in the first flight of the shuttle made this impossible.
On July 11, 1979, Skylab disintegrated when it re-entered the earth's atmosphere after a worldwide scare over its pending crash. The debris stretched from the south-east Indian Ocean into Western Australia. Additional Details: Skylab 1. References: 1 , 2 , 5 , 6 .
Manned two crew. Docked with Salyut 6. Transported to the Salyut-6 orbital station the ninth international crew under the INTERCOSMOS programme, comprising L I Popov (USSR), and D. Prunariu (Romania), to conduct scientific research and experiments. Recovered May 22, 1981 13:58 GMT. References: 1 , 2 , 6 , 32 , 33 , 51 .

Docked with Mir at the Kvant port at 23:51 GMT on May 16 1998, bringing supplies and scientific experiments to the station. Undocked 09:28 GMT on August 12 1998 in order to clear the port for Soyuz TM-28. Deorbited over Pacific Ocean on October 29, 1998.
