      NASA's Aura research satellite was launched on Jul 15. The Boeing Delta
      7920 rocket took off from Space Launch Complex 2-West at Vandenberg AFB
      and reached a 185 x 691 km x 98.2 deg transfer orbit 11 minutes later.
      At apogee a second burn placed Aura in a 673 x 681 km x 98.2 deg orbit.
      The Delta rocket separated and made two more burns to change its
      inclination and lower perigee to 202 x 673 km x 103.0 deg, ensuring that
      the rocket will reenter quickly. Aura carries a hydrazine propulsion
      system to maintain its orbit. When it reaches its final orbit of 705 km,
      it will form part of the "A-Train", a constellation of remote sensing
      satellites in the same afternoon-ascending-node, sun-synchronous,
      orbital plane providing coordinated observations. Aqua leads the
      A-train, with Aura trailing; smaller satellites will be launched
      inbetween the two.

      Aura is EOS Chemistry-1, the third large satellite in the Earth
      Observing System series, with a launch mass of 3112 kg. The spacecraft,
      built by Northrop Grumman Space Technology (formerly TRW), carries an
      infrared radiometer and spectrometer, an ultraviolet/visible ozone
      monitoring spectrometer, and a microwave sounder, and will study ozone
      and pollutants in the atmosphere.

      Arianespace launched the Canadian Anik F2 communications satllite on
      July 18. The second uprated Ariane 5G+ took off from Kourou at 0044 UTC
      as flight V163, vehicle 519. The core stage entered a 44 x 1553 km x 7.1
      deg orbit at 0053 UTC and separated from the EPS upper stage. The core
      stage reentered over the Pacific after one orbit, at around 0223 UTC.
      The upper stage shut down at 0111 UTC and put Anik F2 in a 631 x 38370
      km x 6.7 deg geostationary transfer orbit.

      Anik F2 is a Boeing 702 model satellite with a mass of 5965 kg at
      launch, and will provide high speed internet and digital communications
      across North America. It includes C-band, Ku-band and Ka-band
      communications payloads, a 490N bipropellant apogee engine and four
      XIPS-25 ion thrusters for orbit control. The apogee engine was
      fired for the first time on Jul 24 to raise perigee to 5900 km.

      Russia launched a new Parus navigation satellite on Jul 22, naming it
      Kosmos-2407. The 820 kg satellite was launched into a 951 x 1006 km x
      83.0 deg orbit using a Kosmos-3M rocket from the northern launch site at
      Plesetsk.

      Tan Ce 2, the second probe in the Chinese-European Double Star
      magnetospheric research program, was launched from the Taiyuan Space
      Center on Jul 25. The CZ-2C/SM rocket entered a 666 x 38566 km x 90.1
      deg polar orbit, complementing the 28-degree equatorial Tan Ce 1
      launched from Xichang last year and the four European Cluster satellites
      in deeper 22000 x 116000 km x 89 deg Earth orbits. Tan Ce 2 has a mass
      of 343 kg.


      Registration of satellites with the UN
      ---------------------------------------

      I've updated the UN satellite registry data on my web page.

      France has updated its registration of satellites with the United Nations.
      In UN document ST/SG/SER.E/445,
      <A HREF="http://www.oosa.unvienna.org/Reports/Regdocs/ser445F.pdf">
      http://www.oosa.unvienna.org/Reports/Regdocs/ser445F.pdf,
      </A>
      submitted to the UN on 2004 Mar 4, it
      gave a new list of satellites superseding previous information, which
      includes the registration of 22 previously unregistered satellites.
      Although
      I congratulate France on these corrections, regrettably there are
      many errors in the part of the document covering earlier years
      of the French space program; these errors are documented at

      <A HREF="http://www.planet4589.org/space/un/france.html">
      http://www.planet4589.org/space/un/france.html
      </A>

      In its latest submission to the UN, Russia for the first time since 1966
      (with an arguable exception in 1985) failed to register one of its
      satellites - the Gruzomaket dummy payload launched in December 2003 on
      the first Strela test launch. The submission confirms the name of
      2004-05A as Molniya-1T but surprisingly gives the official name of
      2004-10A as Globus-1 instead of Raduga-1 (the Globus-1 name was
      previously classified and Raduga-1 had been used as a cover name).
      Meanwhile, the USA remains the main culprit for unregistered and
      erroneously registered satellites - although most of these errors are
      due to bureaucratic sloppiness, the 2003-54C classified surveillance
      payload was mendaciously registered as "USA 173 debris" despite the fact
      that independent observers have seen the satellite maneuver. Finally,
      the Intelsat satellites remain unregistered by the UK.
