Vega Launch Vehicle & Qualification THE FIRST INTERNATIONAL LARES WORKSHOP VEGA LAUNCH VEHICLE & QUALIFICATION ( LARES) MISSION CHARACTERISTICS LARES WS 3-4/July/2009 1 THE FIRST INTERNATIONAL LARES WORKSHOP ¾ Vegaaisis aafoufour stage vehicle mainl y based on solid propulsion, with ahigh a high level of integration within the Ariane LV family Design drivers are: • P/L & customer comfort • Launch Cost • Missi on flex ibility ••RReeabtyliability LARES WS 3-4/July/2009 2 VEGA LV CHARACTERISTICS ¾ The Vega LV is designed for a range of missions covering the ijinjecti on of one payldload itintocilircular Low EthEarth ObitOrbits (LEO), with altitudes ranging from 300 km to 1500 km and with inclinations ranging from nearly equatorial (5.2°)uptoSun Sy nchronou s Orbits ¾ The injected Payload masses range is required from a miiinimum of 300 Kguptoamaximum of 2500 Kg, as appropriate according to orbit altitude and inclination. ¾ The Vega LV is designed to be compatible, in the above mentioned range of orbits, with the capability for multiple payloads delivery, defined as follows : - Injection of two payloads, in the mass range of 300 – 1000 Kg; - Injection of one main ppyayload and up to six micro-satellites, in a piggyback configuration, with mass of the order of 100 kg. LARES WS 3-4/July/2009 3 VEGA LV TYPICAL MISSION PROFILES ¾ Earth observation, scientific and meteorological satellites delivered directly into Sun Synchronous Orbit (SSO), Polar Circular Orbit or Circular Orbits with varied inclinations and in Low Earth Orbit (LEO). ¾ Vega AVUM’s multiple burn cappyability offers excellent flexibility to a wide range of elliptical and circular orbits. ¾ A typical flight profile begins with a sub-orbital ascent performed by Vega’s three solid propellant stages, followed by several (up to five) burns of the AVUM. ¾ The final AVUM burn is made for the stage’s own reentry or orbit disposal, in order to comply with the stringent rules to reduce the orbital debris risk.

This work has been developed in the framework of the LARES mission of the Italian Space Agency (ASI). The LARES satellite has been built to test, with high accuracy, the frame–dragging effect predicted by the theory of General Relativity, specifically the Lense–Thirring drag of its node. LARES was the main payload in the qualification flight of the European Space Agency launcher VEGA. A concern arose about the possibility of an impact between the eight secondary payloads among themselves, with LARES and with the last stage of the launcher (AVUM). An impact would have caused failure on the payloads and the production of debris in violation of the space debris mitigation measures established internationally. As an additional contribution, this study allowed the effect of the payload release on the final manoeuvers of the AVUM to be understood. Keywords: LARES, VEGA, launchers, space debris, collisions. 1. INTRODUCTION On February 13, 2012, the European Space Agency’s VEGA qualification flight inserted into orbit the LARES (LAser RElativity Satellite) satellite (Ciufolini et al.

At the very foundation of Einstein’s theory is the geodesic motion of a small, structureless test-particle. De- pending on the physical context, a star, planet or satellite can behave very nearly like a test-particle, so geodesic motion is used to calculate the advance of the perihelion of a planet’s orbit, the dynamics of a binary pulsar system and of an Earth orbiting satellite. Verifying geodesic motion is then a test of paramount importance to General Relativity and other theories of fundamental physics.

  • Satellite Laser Ranging Tracking Through the Years C. Noll NASA
    Satellite Laser Ranging Tracking Through The Years C. Noll NASA Goddard Space Flight Center, Code 690, Greenbelt, MD 20771, USA. [email protected] Abstract Satellites equipped with retroreflectors have been tracked by laser systems since 1964. Satellite laser ranging supports a variety of geodetic, earth sensing, navigation, and space science applications. This poster will show the history of satellite laser ranging from the late 1960’s through the present and will include retro-equipped satellites on the horizon. Satellite Tracking History Initial laser ranges to a satellite in Earth orbit took place in 1964 with the launch of Beacon Explorer-B (BE-B), the first satellite equipped with laser retroreflectors. Since that time, the global network of laser ranging sites has tracked over eighty satellites including arrays placed on the Moon. Satellite and Lunar laser ranging continue to make important contributions to scientific investigations into solid Earth, atmosphere, and ocean processes. SLR also provides Precise Orbit Determination (POD) for several Earth sensing missions (e.g., altimetry, etc.), leading to more accurate measurements of ocean surface, land, and ice topography. Several of these missions have relied on SLR when other radiometric tracking systems have failed (e.g., GPS and DORIS on TOPEX/Poseidon, PRARE on ERS-1, GPS on METEOR-3M and GFO-1) making SLR the only method for providing the POD required for instrument data products. A list of satellites equipped with retroreflectors (past, current, and future) and tracked by SLR is shown in Table 1. The table summarizes the data yield (approximate through 2014) and includes a list of any co-located instrumentation (e.g., GNSS, DORIS, or PRARE).

[email protected] ABSTRACT Today different groups started to manufacture cubesats because of the low cost of manufacturing and launching the satellites. With the growth of cubesat manufacturing, the scientist has tried to produce the small launchers to respond the needs of new researchers and young scientists. In 1980 the U.S.A. manufactured the commercial small launcher and starting launch in 1990. Also Russia with improvement of their ballistic missile and performing changes and improvement tried to manufacture small launchers with a minimum cost to launch the cubesat in the planed orbits. The cubesat will be launched into space together with other cubesats inside a so called P-pod it will be placed on top of the launch vehicle as a secondary payload and a principal feature of the cluster launch cubesat is to mitigate the technical and financial risk shared by the orbital deployers who are partners in a particular launch.
