      Shuttle and Station

      Carl Walz and Dan Bursch made a spacewalk on Feb 20 using the Station's
      Quest airlock. Depressurization was at around 1134 UTC and
      repressurization was at 1725 UTC. The spacewalk involved doing some
      preparatory work with cables and thermal covers in advance of the
      spacewalks planned for STS-110 and the installation of the S0 truss. It
      was also intended to check out proper functioning of the Quest airlock,
      which had some minor problems on its first use in Jul 2001. The last two
      Expedition-4 spacewalks were made from the Russian Pirs airlock.

      Launch of STS-109 is scheduled for Mar 1.

      Recent Launches

      The first Lockheed Martin Astronautics Atlas 3B was launched on Feb 21.
      The Atlas 3B features the new Common Centaur stretched two-engine upper
      stage, also planned for use on the Atlas 5.

      Atlas AC-204 placed the Echostar 7 communications satellite in
      geostationary transfer orbit. The Atlas III first stage, using a Russian
      RD-180 main engine, fired first, followed by the first burn of the
      Centaur, which entered a 185 x 193 km x 28.1 deg parking orbit. At
      1305 UTC the Centaur burned again to achieve the final 245 x 57060 km x
      22.6 deg transfer orbit and separated from Echostar.

      Arianespace launched an Ariane 44L from Kourou on Feb 23. The Loral
      FS-1300HL-class Intelsat 904 satellite it placed in a 176 x 35812 km x 7.0
      deg geostationary transfer orbit will be used for Indian Ocean region
      communications. Intelsat 904 has a dry mass of 2350 kg and carries
      a further 2330 kg of fuel.

      Arianespace had another success on Mar 1 when the Ariane 5 returned to
      flight with mission V145/vehicle 511. This vehicle, the first Ariane 5
      to use the 17-m Long Fairing and the first to launch north from Kourou,
      placed the European Space Agency's Envisat polar platform in orbit.
      Originally envisaged as an automated polar orbiting segment of the
      Space Station, and later descoped to become something like the
      European equivalent of NASA's Earth Observing System, Envisat
      uses a new modular satellite bus built at Matra Marconi Space/Bristol,
      now shut down - final integration was done at ESTEC in the Netherlands.
      The service module (SVM) is based on the SPOT 4 design; prime contractor
      is Astrium (Dornier). Envisat has a dry mass of 7911 kg and carries
      300 kg of hydrazine for orbit adjust. The active C-band phased array
      ASAR radar imaging antenna is 1.3 x 10m in size; Envisat also carries
      atmospheric radiometers and spectrometers and a radar altimeter.

      The V145 flight profile was quite different from earlier Ariane 5 GTO
      launches where the EPC core stage usually reached a marginal orbit. In
      this case EPC separation at 350 km high 10 min after launch left the EPC
      in a suborbital trajectory impacting in the Arctic; the EPS final stage
      with Envisat only achieved a positive perigee at 22 minutes after
      launch, with a circular 790 km sun-synchronous orbit reached at 25 min
      after launch.

      Kosmos-2387 was launched on Feb 25 from Plesetsk. The satellite,
      built by TsSKB-Progress of Samara, is a Kobal't-class imaging
      spy satellite. It carries two small film capsules and a large
      reentry module. The KVR (Russian Space Forces) launched it on
      a Soyuz-U into a 165 x 344 km x 67.1 deg orbit. The previous
      mission of this class, Kosmos-2377, flew from May to October last year.
