Pioneer 11 was the second mission to investigate Jupiter and the outer solar system and the first to explore the planet Saturn and its main rings. Pioneer 11, like Pioneer 10, used Jupiter's gravitational field to alter its trajectory radically. It passed close to Saturn and then it followed an escape trajectory from the solar system.

  • Mir News 249: Progress-M27 - . Nation: Russia. Program: Mir. Flight: Mir EO-18. On 9.04.1995 at 2133 UTC this freighter will be launched from Baykonur for a flight to the Mir-space station. If all goes according to plan the ship will dock at the for ward (P.Kh.O.) port on 11.04.1995 at abt 2058 UTC. Approach and docking will be in the automatic mode by the system Kurs. The captain of Mir is ready to take over manually by the TORU system in case of problems during the automatic approach.

    ALTERATIONS:

    During the Mir's pass over here during orb. 52158, on 5.04.95 TsUP informed the crew about some alterations of the recent planning: 1. Immediately after the arrival of Progress-M27 the cosmonauts will have to work on the gyrodynes. This on request by the Americans. In their opinion the complex needs 12 well functioning gyrodynes. This means that the first EVA planned for 28.04.95 will be put back to the beginning of May, possibly to 1.05.95. 2. The launch of the module Spektr on schedule for 10.05.95 has been put back to 20.05.95. One of the causes of this delay is the installation of equipment on Spektr to make the use of the system TORU by the Mir-crew possible if during the docking operation the automatic system Kurs fails. 3. Though not confirmed thus far the delay of the launch of the Spektr might also put back the launch date of the Atlantis for the docking mission by appr. 10 days.

    GFZ-1: Progress-M27 also has to deliver to the Mir-complex the normal cargo (food, fuel, water, spare parts, experiments, etc.) a small satellite named GFZ-1. GFZ-1 is a spherical satellite with a mass of 20 KG and a diameter of appr. 20 CM. GFZ-1 has been constructed by the German firm Kayser-Threde (Munchen) and will be used by the Geoforschungszentrum Potzdam for geodetic experiments by laser reflectors. GFZ-1 makes it possible to deliver highly accurate measurements of the Earth's gravitation field. Shortly the Mir-crew will launch GFZ-1 for its autonomous flight of appr. 2 years.

Flight: Mir NASA-3; Mir EO-23. Spacecraft: Progress M. Duration: 86.60 days. Completed Operations Date: 1997-07-02 06:31:45 . Decay Date: 1997-07-02 06:31:45 . USAF Sat Cat: 24757 . COSPAR: 1997-014A. Apogee: 393 km (244 mi). Perigee: 375 km (233 mi). Inclination: 51.7000 deg. Period: 92.20 min. Unmanned resupply vessel to Mir. It carried supplies for the Mir station and repair equipment for Mir's oxygen generators, replacement oxygen-generating 'candles' and a pair of new spacesuits. Docked with Mir at the rear Kvant module port on 8 Apr 1997 17:30:03 GMT. The Mir complex raised its orbit by 5 km on 15 Apr 1997 at 12:00 GMT, using Progress M-34's engine. Undocked on 24 Jun 1997 10:22:50 GMT. It was then used to perform a redocking test using newly developed remote-control procedures which were to replace the automatic system that Russia could no longer afford to buy from Ukraine. At 25 Jun 1997 09:18 GMT Mir commander Tsibliev was remotely commanding the approach of Progress to the Kvant module. This involved guiding the Progress via a television monitor. The Progress was difficult to see against the cloudy earth background at the time of the attempted docking. It went off course and collided with a solar array on the Spektr module and then the module itself. A large hole was made in a solar panel, one of the radiators was buckled, a hole was punched into Spektr's hull, and the module began to depressurize. This was not a slow leak - the crew heard a hissing sound and felt their ears pop. They disconnected the power cables leading from Mir to the main station and closed the hatch on the core module transfer section that led to Spektr. The Spektr module became fully depressurized, remaining docked to Mir with its docking hatch open. The loss of electrical connection between Spektr's solar panels and the main station cut the available power supply to the station, crippling its operations until later repairs reconnected the electrical lines. Tsibliev was also the pilot on a previous orbital collision, when he banged Soyuz TM-17 into Mir in Jan 1994. After the return of the crew to earth he was found to be to blame for the incident, although the fines assessed were later dismissed. The Progress M-34 cargo ship was backed to a safe distance from the station and was destroyed in reentry on 2 Jul 1997 06:31:50 GMT. Total free-flight time 9.90 days. Total docked time 76.70 days.

Type: Manned space station. Flight: Mir NASA-6; Mir EO-25. Spacecraft: Mir. The crew succeeded in completing repair of the damaged Spektr solar panel. However the EVA was cut short when Mission Control in error commanded the Mir to drift. This was then misdiagnosed as a depletion of fuel of the VDU orientation engine, and the crew was ordered back into the station.

    Ahead: Week 25 of Increment 16.

    Having passed Day 180 of her flight, Dr. Peggy Whitson ended her fourth session with the NASA/JSC experiment NUTRITION w/Repository by collecting a final urine sample upon wakeup for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS). The sampling kit was then stowed away. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)
