14:03 GMT - . Launch Site: Wallops Island. Launch Complex: Wallops Island LA4. Launch Vehicle: Little Joe 1.
  • Mercury LJ-5B - . Nation: USA. Agency: NASA. Spacecraft: Mercury. Apogee: 4.00 km (2.40 mi).

    Little Joe 5B (LJ-5B) was launched from Wallops Island to test the Mercury escape system under maximum dynamic pressure conditions. At the time of lift-off, one of the launch vehicle rocket motors did not ignite until after 4 seconds had elapsed. This delay caused the launch vehicle to pitch into a lower trajectory than had been planned, with a result that the abort maneuver experienced greater dynamic pressures than had been specified in the flight test plan. Other than this, all other sequential systems operated according to plan, and after landing, a normal helicopter recovery was accomplished. Thus, all test objectives were met and were actually exceeded because the spacecraft withstood the higher dynamic pressures.

  • N1 Plans - . Nation: Russia. Spacecraft: L3-1963, OS-1 (1965), TMK-1.

    An Inter-Institution Soviet considers Korolev's N1 plans. He believes the first booster will be launched in 1965. The N1 is to have a payload capability of 75 tonnes to a 250 km altitude orbit, 50 tonnes to a 3000 km altitude orbit, and 16 tonnes in geostationary orbit. It could launch spacecraft capable of landing men on the moon and returning them to earth, or manned flybys of Mars or Venus. Three to ten launches would be needed for such missions, with the components being docked together in low earth orbit. The N1 can also be used to launch a large space station for military research. After the N1 discussion a decision is made that cosmonauts will not have to spend more than three to four days in a spacecraft mock-up on the ground to prove their readiness for flight. A simulation of the entire flight duration is not necessary.

  • Mir News 478: Progress M1-2 - . Nation: Russia. Program: Mir. Flight: Soyuz TM-30.

    This freighter with on board supplies of air, water and fuel for the Mir-station departed from Baykonur to Mir on 25.04.00 at 20.08.02 UTC. The freighter had to dock at Mir on 27.04.00 at about 2130 UTC , so 10 minutes after Mir and Progress M1-2 for us in Western Europe had disappeared behind the eastern horizon.

    Progress M1-1: This old freighter separated from Mir on 26.04.00 at 1633 UTC for decay over the Pacific east of New Zealand at 1927 UTC.

    Docking Progress M1-2: Approach and docking were executed with the help of the system Kurs. All went flawlessly and smoothly. The freighter docked at the aft docking port (Kvant-2 +X axis) on 27.04.00 at 21.28.48 UTC. During the pass for Western Europe just before the docking (orbit 81124, 2116-2121 UTC) radio traffic revealed that all was going well. Just before LOS for my position the distance to the docking part was 60 Meters and Progress M1-2 was proceeding exactly on course.

    During the next pass for my position in orb. 81125, 2252-2258 UTC, the crew reported that they just had opened the hatches to Progress M1-2. The equalisation of the pressures between the station and the freighter lasted long this time. Kaleri said that the cargo bay of the Progress M1-2 was only half full. The air-seal was in good order, but there had been some variations in the air pressure, which in his opinion were caused by the differences in temperature. In 30 minutes the pressure decreased by 4 MM mercury, and then the decrease stopped. At last the pressure inside the station was 687 MM. The crew still had to install the clamps between the Progress M1-2 and the Kvant-1 docking port. These clamps make it impossible for the freighter to wander away.

    Meanwhile the control computer Svet had been switched on and Kaleri loaded a number of commands into Svet for the automatic control of a number of systems.

    Then the cosmonauts crept into their sleeping-bags. (The bunks for eventual tourists did not yet arrive.). For your scribe a good reason to lay down in the arms of Morpheus.

    Orbit corrections: The strong solar maximum causes an increased decay of the orbit altitude of the Mir-space station. Some time ago this decay was about 100 or 150 Meters a day, now this is 4 or 5 times more. The only solution is to lift the orbit of the complex by the use of the engines of the PrM-1 (mostly this is the DPO, the engine for docking and orientation of the freighter is used for that purpose), but once the engines of the Soyuz-TM30 were used (on17.04). Later some more corrections had been given by the DPO of Progress M1-1. So it was difficult to calculate accurate orbit predictions.

    Just before the separation of the Progress M1-1 from the complex on 26.04 the DPO of that ship gave another impulse to lift the complex.

    More orbit corrections can be expected during the next days, now with the help of the DPO of Progress M1-2.

    The acceleration of the decay of the station causes anxiety at TsUP. More even than the possibly still existing small air leaks in the station. This also means that more money has to be reserved in the budget of the "users" for extra fuel.

    From the beginning of the 28th Main Expedition the crew has been very busy with air-seal checks in several compartments and modules. This search was intensified on 18 and 19.04.00. The crew worked with special equipment, which had been brought to the station together with the present crew. They spoke about an instrument called Bar and a thermo-hygrometer. The cosmonauts had to disconnect cables in the PKhO (the transition section) to make it possible to close the hatches through which these cables are deployed. The co-ordination with TsUP during these activities was very good and all went well during this risky work.

    On 18.04 the crew almost knew where the small leak was and when they were sure about the location they closed or plugged the leak with a cap of stopper. During traffic in the pass on 19.04 in orbit 80988, 0701-0721 UTC TsUP and the crew discussed what kind of plug they should use. In the next pass (orb. 80989, 0834-0841 UTC) Kaleri reported that the "hissing sound ceased".

    Thus far it is not fully clear whether this leakage was the only one. Some of the experts at TsUP were not sure for 100%. The air-pressure checks are still going on, but less intensive than before the detection of the leak. The leak was in a valve in the hatch between the PkhO and the &"vacuumed"; module Spektr.

    To be honest the crew of this expedition and the experts at TsUP did a great job during the last weeks. In the first place there was the reactivation of the important life support systems, but also the fact that they managed to keep these systems operational and succeeded in the detection of that small leak and the liquidation of that problem.

    And let us not forget the flawless automatic approach and docking of the Progress M1-2 which had been equipped by a better system Kurs.

    But another fact is less positive: nobody is queuing up in front of the desks where tourists can book a trip to the Mir-space station. And thus far there has not been a single satellite begging Mir for repair or maintenance. In fact a very good thing for the brave crew of Mir will need all their time to keep their iron lung operational.

    Soyuz TM-32 was designated ISS flight 2S by NASA and EP-1 (Visiting Crew 1) by RKK Energia. Soyuz TM-32 was a fresh lifeboat for the station; the Soyuz TM-31 crew themselves would return in Soyuz TM-31, which was at the end of its rated in-space storage tie. Dennis Tito's inclusion in the crew created controversy between NASA and the Russians since he was the first space tourist to fly to ISS. He had originally paid to fly to the Mir station but funds ran out to keep that station in orbit. Soyuz TM-32 docked with the -Z port on Zarya at 0758 GMT on April 30 after Endeavour had departed.. The crew transferred their customized reentry seat liners to Soyuz TM-31, at which point TM-32 became the Station's rescue vehicle. After a six day stay, the Soyuz TM-32 crew returned to earth aboard Soyuz TM-31. The Expedition 3 crew entered Soyuz TM-32) on October 19, 2001 and undocked from the nadir port of Zarya at 1048 GMT, flying it out and then sideways a few meters before approaching the station again to dock with the Pirs nadir port at 1104 GMT. This freed up Zarya for the arrival of a new Soyuz. The docking port at the aft end of Zvezda was occupied by the Progress M-45 cargo ship.
