Ariane 5 liftoff
 
21 December 2016
An Ariane 5 lifted off this evening to deliver two telecom satellites, Star One-D1 and JCSat-15, into their planned orbits.
Arianespace announced liftoff at 20:30 GMT (17:30 local time, 21:30 CET) from Europe’s Spaceport in Kourou, French Guiana for a dual payload mission lasting about 43 minutes.
Star One-D1, with a mass of 6433 kg at liftoff, was the first satellite to be released, about 29 minutes into the mission. The 3400 kg JCSat-15 was released 14 minutes later.
Star One-D1, owned by Embratel Star One, will handle broadcasting, broadband, Internet access and other digital applications over Brazil, Latin America, Central America, Mexico and the Caribbean.
JCSat-15, owned by SKY Perfect JSat, will offer a range of communications services for Japan, including broadcasting, data transfer, and maritime and aeronautical applications for the Oceania and Indian Ocean regions.
Both satellites are designed to last more than 15 years.
The payload mass for this launch was 10 722 kg. The satellites totalled about 9833 kg, with payload adapters and carrying structures making up the rest.
Flight VA234 was the 90th Ariane 5 launch, and the seventh this year.

Lanzamiento de otros cuatro satélites Galileo

Galileo liftoff
 
17 noviembre 2016
Cuatro nuevos satélites Galileo acaban de ser lanzados a bordo de un cohete Ariane 5, acelerando así el despliegue del nuevo sistema de navegación por satélite.
El Ariane 5, operado por Arianespace, despegó del Puerto Espacial Europeo de Kourou, Guayana Francesa, a las 13:06 GMT (14:06 CET, 10:06 hora local), transportando en su interior los satélites 15 a 18 de Galileo. El primer par de satélites se soltó 3 horas, 35 minutos y 44 segundos tras el despegue, mientras que el segundo lo hizo 20 minutos después.  
Todos ellos se encuentran ya a la altitud prevista, tras separarse sin problemas del nuevo dispensador diseñado específicamente para operar con cuatro satélites. 
A lo largo de los próximos días, los ingenieros trasladarán los satélites hasta sus órbitas operativas finales y comenzarán las pruebas para garantizar que están listos para unirse a la constelación. Se espera que esto suceda en unos seis meses.
 
Galileos deployed

Finalizada esta misión, serán 18 los satélites del sistema Galileo. 
Con los que ya están en órbita, la Comisión Europea podrá declarar el comienzo de los primeros servicios, previstos para finales de este año. 
Los anteriores 14 satélites fueron lanzados de dos en dos a bordo de cohetes Soyuz-Fregat.

“Ahora que podemos aprovechar la potencia de los cohetes Ariane 5, esperamos completar más rápidamente el despliegue de la constelación Galileo y pasar a su pleno funcionamiento”, comenta Paul Verhoef, director del Programa Galileo y de las Actividades de Navegación de la ESA. 
Están previstos otros dos lanzamientos con cohetes Ariane 5 en 2017 y 2018. El sistema de 24 satélites, más los de reserva, debería estar en posición en 2020. 
Daniel Neuenschwander, director de Lanzadores de la ESA, explica: “Con este, que constituye el 75.º lanzamiento exitoso ininterrumpido, el Ariane 5 bate un nuevo récord entre los lanzadores europeos, demostrando una vez más su fiabilidad”.

ENGLISH VERSION :

Galileo liftoff
 
17 November 2016
An Ariane 5 rocket has launched four additional Galileo satellites, accelerating deployment of the new satellite navigation system.
The Ariane 5, operated by Arianespace, lifted off from Europe’s Spaceport in Kourou, French Guiana at 13:06 GMT (14:06 CET, 10:06 local time) carrying Galileo satellites 15–18. The first pair was released 3 hours 35 minutes and 44 seconds after liftoff, while the second separated 20 minutes later. 
The Galileos are at their target altitude, after a flawless release from the new dispenser designed to handle four satellites.
 Over the next few days, engineers will nudge the satellites into their final working orbits and begin tests to ensure they are ready to join the constellation. This is expected to take six months or so.
 
Galileos deployed

This mission brings the Galileo system to 18 satellites.
The satellites already in orbit will allow the European Commission to declare the start of initial services, expected towards year’s end.
The previous 14 satellites were launched two at a time using the Soyuz–Fregat rocket.

“Now that we can rely on the powerful Ariane 5, we can anticipate the quicker completion of Galileo deployment, permitting the system to enter full operation,” remarked Paul Verhoef, ESA’s Director for the Galileo Programme and Navigation-related Activities.
Two additional Ariane 5 launches are scheduled in 2017 and 2018. The full system of 24 satellites plus spares is expected to be in place by 2020.
“With this 75th successful launch in a row, Ariane-5 sets a new record within European developed launchers and proves once more its reliability, " said Daniel Neuenschwander, ESA’s Director for Launchers.

  • Description
    The recently separated Galileo satellites 15–18 seen in space as four closely clustered dots above their Ariane 5 EPS upper stage, which is venting propellant (the brilliant cloud from both sides of the EPS) as part of its passivation process.
    The two brighter spots/areas at each side is due to the passivation process itself, in which − after the opening of the valves − the pressure falls quite quickly and therefore a higher concentration of discarded propellant is found further from the EPS.
    This image was acquired by the CNES/CNRS-operated TAROT telescope on Réunion Island at 17:23 GMT (18:23 CET) on 17 November 2016, approximately 21 minutes after the second separation of paired Galileo satellites. The agile TAROT telescopes are used to hunt out optical evidence of Gamma-ray burst events as well as observe and catalogue space objects in high orbit.
    About TAROT
    TAROT refers to 'Télescope à Action Rapide pour les Objets Transitoires – Rapid Action Telescope for Transient Objects' and comprises a network of telescopes, which is jointly operated by the French space agency (CNES) and France's CNRS - Centre national de la recherche scientifique (Artemis and IRAP Laboratories).
    TAROT consists of two 25-cm aperture instruments located at the Calern Observatory (part of the Observatoire de la Côte d'Azur, France), the La Silla Observatory (European Southern Observatory, Chile), and an 18-cm telescope at Les Makes Observatory (Reunion, France). Since 1999, TAROT has conducted observations of Resident Space Objects (RSO) − mostly debris − on geostationary orbit, and of passing objects in eccentric (such as Geostationary transfer orbit or Medium Earth Orbit). Such observations are used to feed an automatic cataloguing system of RSOs.

Galileo’s Ariane 5 arrives at Europe’s Spaceport

Unloading Ariane 5
 
30 August 2016
The first Ariane 5 rocket modified to carry four Galileo satellites into orbit has arrived at Europe’s Spaceport in French Guiana for a November launch.
So far, 14 Galileo satellites have been launched two by two on Soyuz rockets from French Guiana. This inaugural launch by Ariane 5 will boost that number to 18.
The MN Colibri roll-on/roll-off ship, built to transport European rocket elements, reached French Guiana’s Pariacabo Port on 22 August.
The cargo included Ariane’s cryogenic core stage, its upper stage and payload fairing. This Ariane variant is based on the launcher previously used to place ESA’s 20 tonne Automated Transfer Vehicle supply vehicle into low orbit.
 
Transfer to Spaceport

This version has to carry a lower mass – four fully fuelled 738 kg Galileo satellites plus their dispenser – but needs to take it up to the much higher altitude of 23 222 km.
The target orbit is actually 300 km below the Galileo constellation’s final working altitude: this leaves Ariane’s upper stage in a stable ‘graveyard orbit’, while the quartet of satellites manoeuvre themselves up to their final height.
 
Upper stage being transported

The four satellites to be launched by this Ariane 5 are due to be flown to French Guiana next week from ESA’s technical centre in Noordwijk, the Netherlands.
The Galileo satellite bus is built by OHB in Bremen, Germany, with the navigation payloads coming from Surrey Satellite Technology in the UK, involving supplied from all across Europe. They are then tested in simulated launch and space conditions in Noordwijk before being accepted for launch.
