  • Amateur Club de L Espace This launch was the first flight of the Ariane 42L variant with two liquid strapon boosters The basic Ariane 4 variant without strapons is the 40 which has made two flights The 42P 4 flights and 44P 2 flights have two and four liquid strapons the 44LP 6 flights has two liquids and two solids and the 44L 13 flights has 4 liquid boosters Ariane 4 has made a total of 28 flights of which one was a failure Its main rival the Delta II has now made 34 flights with no failures The latest Delta II flight also marked the 600th launch of McDonnell Douglas Thor first stage The Thor started life in 1957 as an intermediate range ballistic missile it is one of the most used large rocket stages beaten only by the Minuteman about 760 launches of the M55A1 M55E1 first stage and OKB 1 s R 7 ICBM at least 1490 launches of which 1424 put a payload in orbit since pre Sputnik suborbital tests in 1957 to the Apr 27 launch of Kosmos 2243 The Delta s payload was a Rockwell Navstar navigation satellite GPS SVN 37 which carries an atomic clock and operates in a 20000 km high circular orbit The last Navstar launch GPS SVN 31 carried an interesting secondary payload the SEDS tether experiment Enrico Lorenzini one of the scientists involved in the experiment graciously gave me some technical details on the mission so I include a detailed recap of the flight below Opinions and errors are of course mine The SEDS 1 Mission Space tethers were experimented with on the Gemini XI and XII missions in 1966 with the idea of eventually using them to provide artificial gravity At the time the true potential of space tethers was not understood Recent theoretical work has led to the idea that long tethers can be used to generate electricity alter a spacecraft s orbit and deliver probes to study the upper atmosphere In August 1992 an ambitious Italian Space Agency experiment on the Shuttle TSS 1 attempted to deploy a long tether However there were problems with the deployer mechanism and the tether only got out to a quarter of a kilometre Although a lot was learned about tether dynamics during retrieval a time when the tether is least controllable the mission was a failure The first fully successful tether mission was carried out on 1993 Mar 30 The SEDS Small Expendable Deployer System consisted of a small 10 kg deployer cylinder 33 cm long and a tiny 23 kg satellite end mass of similar size The satellite was connected to the cylinder by a rope made of Spectra 1000 which was 0 75 mm in diameter and 20 km long The cylinder remained attached to the Delta second stage rocket in orbit Here is a log of the mission events 1993 Mar 30 Time UTC 0309 A Delta model 7925 launch vehicle Delta 219 ignited on Launch

  • Earth in July Launches The spacecraft launched on May 21 has been confirmed as a Resurs F remote sensing flight It is the Resurs F2 model which stays in orbit for around 30 days On May 26 its orbit was 228 x 233 km x 82 6 deg The Arsene amateur radio satellite has successfully fired its SEP Mars apogee motor and is in a 17600 x 37000 km orbit inclined at 1 degree to the equator Its VHF system isn t working right but the S band reportedly is fine A Gorizont communications satellite was launched by Proton on May 27 from Baykonur I don t have any orbital elements yet but a Space News article indicates that the NPO Energiya built Blok DM fourth stage failed leaving the payload either in parking orbit or in an incorrect transfer orbit The Blok DM is separate from the main UR 500K Proton rocket built by NPO Mashinostroeniye and is essentially considered to be part of the payload like IUS stages on Shuttle missions On geostationary orbit missions it burns twice first to go from low circular orbit to geostationary transfer orbit and second to circularize the transfer orbit at apogee A bigger stage is needed for this than for US launch vehicles Russia s launch site in Kazakhstan is at 46 deg North and because of ground range constraints the initial orbit is at 51 degrees to the equator requiring a large velocity change to enter the final equatorial orbit The Blok D series of upper stages was originally developed for the Soviet piloted moon landing program Date Name Launch Vehicle Site Mission INTL DES May 11 1450 Kosmos 2245 Tsiklon Plesetsk Comsat 30A Kosmos 2246 30B Kosmos 2247 30C Kosmos 2248 30D Kosmos 2249 30E Kosmos 2250 30F May
