  • Jul 26 Recent Launches Atlas II flight AC 125 was launched from Complex 36 at Cape Canaveral Air Station on Jul 25 Payload was an HS 601 comsat built by Hughes for the US Navy UHF Followon F7 UHF F O F7 The UHF Followon comsats are used for US Navy fleet communications The Lockheed Martin Atlas II uses a stretched Atlas first stage and a Centaur II liquid hydrogen liquid oxygen second stage The Centaur makes two burns to deliver the HS 601 satellite to geostationary transfer orbit The early UHF F O satellites were launched on Atlas I but with the addition of an EHF extremely high frequency communications package they were moved to the Atlas II Navstar SVN 40 s apogee motor fired successfully prior to Jul 21 and on Jul 23 it was in a 723 65 min 20275 x 20368 km x 55 0 deg drift orbit It has been assigned the telemetry number PRN 10 and will be placed in position E3 to begin service on Aug 12 Meanwhile Navstar 20 launched in 1990 was retired last May 21 it was the first of the Block II GPS satellites to leave service The two comsats launched by Ariane on Jul 9 are reaching their final orbits Arabsat 2A was on station at 26 0 deg E on Jul 23 Turksat 1C was at 31 3 deg E on Jul 22 drifting 0 1 degree per day Table of Recent Launches Date UT Name Launch Vehicle Site Mission INTL DES Jun 4 1234 Cluster F1 Ariane 5 Kourou ELA3 Science FTO Cluster F2 Cluster F3 Cluster F4 Jun 15 0655 Intelsat 709 Ariane 44P Kourou ELA2 Comsat 35A Jun 20 1449 Columbia Shuttle Kennedy LC39B Spaceship 36A Spacelab LMS 1 Jun 20 1845 Kosmos Soyuz

  • to the new stack later today The old stack will eventually be disassembled for refurbishment Recent Launches Another successful Ariane launch Arianespace flight V90 placed two European domestic comsats in orbit on Aug 8 Italsat F2 is a domestic Ka band comsat built by Alenia Spazio for the Italian Space Agency and is operated and owned by Telecom Italia The second satellite Telecom 2D is a Matra Marconi Space Eurostar 2000 satellite owned jointly by France Telecom and the French Defense Ministry V90 used an Ariane 44L rocket with 4 PAL strapon rockets an L220 first stage an L33 second stage and an H 10 3 third stage The H 10 3 entered geostationary transfer orbit and then released Italsat F2 which was mounted on a compartment called SMS a nested bilingual acronym SMS Stretched Mini SPELDA SPELDA Structure Portuese Enceinte de Lancement Double Ariane if I remember correctly Way to go ESA The SMS cover was ejected followed by release of the Telecom 2D which was stored underneath it The two satellites entered a 260 x 36877 km x 5 3 deg transfer orbit Both have US built R 4D liquid apogee engines to raise their orbits to geostationary Italsat F2 made its first burn on Aug 10 raising perigee to 9200 km and lowering inclination to 2 4 deg Telecom 2D was still in its original orbit on Aug 11 Note that Ariane flight V88 never happened the press kit for the June launch was V87 and for the July launch was V89 I assume that the Ariane V501 flight has been retrospectively designated V88 or V87 can anyone confirm The Atlas AC 125 launch was from pad 36A The Progress M 23 launch was probably from pad 1 NASA s DC XA reusable suborbital rocket was destroyed

  • set of instruments including the Advanced Visible Near IR Radiometer and the Ocean Color and Temperature Scanner the NASA TOMS ozone monitor and NSCAT wind speed scatterometer and an experiment to study greenhouse effect gases This was the fourth H II launch H II launches from Tanegashima Space Center Yoshinobu Launch Complex Flight Date Payload Upper Stage Fairing Type H II 1F 1994 Feb 3 VEP Myojo Dummy LAPS 4S OREX Ryusei H II 2F 1994 Aug 28 ETS 6 Kiku 6 LAPS 4S H II 3F 1995 Mar 17 SFU None 4 5D GMS 5 Himawari 5 H II 4F 1995 Aug 17 ADEOS None 5S JAS 2 China launched a Chang Zheng 3 vehicle on Aug 18 from Xichang The CZ 3 third stage entered parking orbit and coasted and then reignited for a second burn to geostationary transfer orbit However the engine shut down prematurely during this second burn leaving the payload in a low orbit The payload is Zhongxing 7 a Hughes HS 376 class comsat for the China Telecommunication and Broadcasting Satellite Corporation Launch was at 1827 Beijing time which I believe to be 1027 UTC The Aug 18 planned launch of NASA s FAST satellite aboard a Pegasus was postponed ten minutes before the expected drop time and the L 1011 carrier plane returned to Vandenberg with the rocket still aboard Plesetsk History There are officially two separate spaceports at Plesetsk in northern Russia Thanks to recent conversations with Igor Lissov and Maxim Tarasenko I ve understood the history of this a little better and though I would share it with you all Orbital launches from Plesetsk began in 1966 Until 1993 the spaceport s true name was NIIP 53 53 y Nauchno Issledovatelskiy Ispytatelnyy Poligon 53rd Scientific Research Test Range Sometime in 1993 the name was changed to GNIIP Gosudarstvennyy Nauchno Issledovatelskiy Ispytatelnyy Poligon State Scientific Research Test Range The NIIP 53 GNIIP base is run by the RVSN Strategic Rocket Forces but in 1982 operation of the orbital pads was transferred to the UNKS space troops and in 1989 the UNKS units at Plesetsk were designated the 1278 y GTsIPKS 1278 y Glavnyy Tsentr Ispytaniy i Primeneniya Kosmicheskikh Sredtsv In Aug 1992 the UNKS became the VKS Military Space Forces of the Russian Federation Then on 1994 Nov 11 the part of GNIIP operated by the VKS including the GTsIPKS headquarters and the orbital launch pads was split off into a separate spaceport the 1 y GIK 1 y Gosudarstvennyy Ispytatelnyy Kosmodrom First State Test Spaceport GNIIP remains in existence alongside 1 y GIK but is used by the RVSN for ballistic missile tests All space launches since Nov 1994 have been from 1 y GIK by the VKS with the exception of the 1995 Start launch which was from GNIIP and was carried out by the RVSN This situation two spaceports right next to each other is not unprecedented From 1959 to 1964 space launches were made from a Navy base

  • study particle acceleration processes with much higher time resolution than previously attempted Orbit of FAST is 351 x 4165 km x 83 0 deg Errata ADEOS launch time is 1996 Aug 17 at 0153 UTC I mistyped the name of Progress M 32 in the launch table I referred to the Korzun crew as EO 24 last week oops It is EO 22 launched aboard Soyuz TM 24 Zhongxing 7 was left in a 200 x 17227 km orbit at 27 2 deg inclination when the CZ 3 third stage shut down 48 seconds too early The HS 376 payload has a Star 30 solid apogee motor which could be fired to raise the orbit but it probably doesn t have enough fuel to make it to geostationary ADEOS 1 has a problem with one of its 20N orbit adjust thrusters and the initial orbital adjustment is being made with the help of smaller thrusters over the period Aug 24 to Sep 8 Initial orbit was 799 x 820 km x 98 6 deg on Aug 29 the orbit was 800 x 810 km x 98 6 deg The Interbol 2 satellite was launched on Aug 29 from Plesetsk It is a Prognoz M2 class satellite also known as Interbol Auroral Probe The Molniya M rocket took off at 0522 00 UTC on Aug 29 The four strapons that make up the first stage separated at 0524 the second stage Blok A core separated at 0526 52 and the third stage shut down at approximately 0530 55 UTC At 0531 00 UTC the Blok I third stage separated from the Blok 2BL fourth stage carrying Interbol leaving it in a 244 x 1192 km x 62 8 deg orbit One second later the MU SAT MICROSATELITE payload was ejected MU SAT is a small experimental payload from the Instituto Universitario Aeronautico de Cordoba Argentina This is the second Argentine satellite following the amateur radio LUSAT At 0628 UTC scheduled the Blok 2BL stage began its burn and at 0631 UTC it separated leaving the Interbol 2 Prognoz M2 article SO M2 No 513 built by NPO Lavochkin in an elliptical orbit of 775 x 19210 km x 62 6 deg Prognoz SO M satellites are normally placed in much more elliptical orbits with apogees around 200000 km but this mission is intended to study the aurora rather than the magnetosphere and solar wind The S2 A Magion 5 subsatellite built in the Czech Republic was due to separate from Interbol 2 to provide spatially resolved auroral measurements Confirmation of Magion 5 separation is still awaited Kosmodrom Baykonur Sergey Voevodin reports that the designation of Baykonur is 5 y Gosudarstvennyy Ispytatelnyy Kompleks Ministerstva Oborony 5th State Test Complex of the Ministry of Defence Its acronym is 5 y GIK or GIK 5 but note that here GIK stands for Kompleks not Kosmodrom as in the case of 1 y GIK at Plesetsk Table of Recent Launches Date UT Name Launch Vehicle
