On Thursday 23 December, the James Webb Space Telescope, safely stowed inside the fairing of ESA’s Ariane 5 launch vehicle, left the final assembly building for roll-out to the launch pad at Europe’s Spaceport in French Guiana.
Webb, no longer in sight since its encapsulation in the fairing on 17 December, has been closely monitored. The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth.
Ariane 5, standing 53 m high on its mobile launch platform was transported along rails from the final preparation building to the launch zone where final health checks and preparations for liftoff will occur.
This includes filling the propellant tanks of the Ariane 5 core stage with liquid oxygen and liquid hydrogen via lines through the launch table.
Final electrical and software configurations will also occur on the launch pad. Webb will switch to internal battery power about 20 minutes prior to liftoff, and within 15 minutes prior to liftoff the observatory and its launch vehicle will both be fully cleared for flight.
Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace.

After its arrival in the final assembly building, on 1 April ESA’s Jupiter Icy Moons Explorer (Juice) was slowly lifted from the air cushion platform on which it sat during its transfer to the building. Following this process, it was lifted over 50 metres into the air, and then carefully lowered onto the top of the Ariane 5 rocket that will carry it into space.
This whole operation was performed under strict safety and cleanliness regulations to keep Juice in prime condition for launch on 13 April. The operators wore bright yellow suits; these are used whenever hazardous operations are carried out, for example when a spacecraft is moved.
Juice is being prepared to launch from Europe’s Spaceport in Kourou, French Guiana. After an eight-year journey to Jupiter, the mission will make detailed observations of the gas giant and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of instruments. The mission will characterise these moons as both planetary objects and possible habitats, explore Jupiter’s complex environment in depth, and study the wider Jupiter system as an archetype for gas giants across the Universe.

On Friday 17 December, the Ariane 5 rocket fairing was closed around the James Webb Space Telescope. This protective fairing, or ‘nose cone’, will shield the telescope during liftoff and its journey through the atmosphere on 24 December.
Earlier this week, Webb was placed on top of Ariane 5 and a protective ‘shower curtain’ was put up to avoid any contamination.
On the day of encapsulation in the fairing, a protective cover on top of Webb was removed and the fairing was lowered down over the observatory and locked in place for liftoff.
This was a particularly delicate operation, assisted by a laser guiding system, because the margins between the folded up observatory (4.5 m wide) and the rocket fairing (5.4 m wide) are small.
The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth.
Now that Webb has been securely attached to its Ariane 5 launch vehicle, and enclosed within its protective fairing, mechanical operations involving the observatory at its launch site in French Guiana have formally concluded.
Final electrical and software configurations will occur on the launch pad during the final hours before liftoff. Webb will switch to internal battery power roughly 20 minutes prior to liftoff, and within 15 minutes prior the observatory and its launch vehicle will both be fully cleared for flight.
Ariane 5’s rollout to the launch pad is scheduled to begin Wednesday 22 December, and this is where final health checks and preparations for liftoff will occur.

The Quantum satellite is being placed in its transport container at Aibus Toulouse before being shipped to Europe's Space Port in Kourou, French Guyana on 24 June 2021.
Quantum, the ESA Partnership Project with Eutelsat, Airbus and Surrey Satellite Technology Ltd, is a pioneering mission preparing the way for the next generation of telecommunications satellites, which will be more flexible by design and so more adaptable to customer needs once in orbit.
Quantum is a shift from custom-designed satellite with one-off payloads to a more generic approach, resulting in unprecedented in-orbit reconfigurability in coverage, frequency and power, allowing complete mission rehaul, including orbital position.
ESA partnered with satellite operator Eutelsat and manufacturer Airbus to design this programme, in response to today's market requiring satellites to be able to respond to changes in geographical or performance demand, either during manufacturing or after launch. This will enable the operator to address emerging business opportunities — even those that appear after it has ordered a satellite.
Such ESA Partnership Projects maximise the benefits to industry thanks to an efficient, co-managed approach that is tailored to commercial best practice

The Ariane 5 launch vehicle which will launch the James Webb Space Telescope was moved to the final assembly building at Europe’s Spaceport in French Guiana on 29 November 2021.
Ariane 5 parts shipped from Europe to French Guiana, have been coming together inside the launch vehicle integration building.
The lower part of the Ariane 5 comprises the cryogenic main core stage (with the Vulcain main engine, oxygen and hydrogen tanks), two solid rocket boosters and the upper composite, including the cryogenic upper stage (with the HM7B engine, oxygen and hydrogen tanks), the vehicle equipment bay – the 'brain' of the launcher, and all supporting structures that will interface with Webb on its adaptor.
A launch table is used to transport the Ariane 5 vehicle between the launch vehicle integration building, the final assembly building and the launch pad.
Webb, now fuelled, will soon be integrated on Ariane 5’s upper stage and then encapsulated inside Ariane 5’s specially adapted fairing.
Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace.

The James Webb Space Telescope was transferred to the final assembly building at Europe’s Spaceport in French Guiana on 7 December 2021, to meet its Ariane 5 launch vehicle.
Stowed inside a special 23-tonne transport container, Webb was protected and monitored throughout the transfer.
Ariane 5 was already moved to the same building on 29 November. Here, adjustable platforms allow engineers to access the launch vehicle and its payload.
The next steps are to hoist Webb to the upper platform which has been prepared so that Webb can be integrated on Ariane 5’s upper stage and then encapsulated inside Ariane 5’s specially adapted fairing.
Webb is scheduled for launch on 22 December from Europe’s Spaceport. Ground teams have already successfully completed the delicate operation of loading the spacecraft with the propellant it will use to steer itself while in space.

The James Webb Space Telescope was fuelled inside the payload preparation facility at Europe’s Spaceport in French Guiana ahead of its launch on Ariane 5.
Webb’s thrusters will use this propellant to make critical course-corrections after separation from Ariane 5, to maintain its prescribed orbit about one and a half million kilometres from Earth, and to repoint the observatory and manage its momentum during operations.
Fuelling any satellite is a particularly delicate operation requiring setup of the equipment and connections, fuelling, and then pressurisation.
Webb’s propellant tanks were filled separately with 133 kg of dinitrogen tetroxide oxidiser and 168 kg hydrazine. Oxidiser improves the burn efficiency of the hydrazine fuel.
These propellants are extremely toxic so only a few specialists wearing Self-Contained Atmospheric Protective Ensemble, or ‘scape’ suits, remained in the dedicated fuelling hall for fuelling which took 10 days and ended on 3 December.
The next steps will start soon for ‘combined operations’. This is when specialists working separately to prepare Webb and Ariane 5 will come together as one team. They will place Webb atop its Ariane 5 launch vehicle and encapsulate it inside Ariane 5’s fairing.
Then, no longer visible, Webb, joined with its Ariane 5 launch vehicle will be transferred to the Final Assembly building for the final preparations before launch.

On Thursday 23 December, the James Webb Space Telescope, safely stowed inside the fairing of ESA’s Ariane 5 launch vehicle, left the final assembly building for roll-out to the launch pad at Europe’s Spaceport in French Guiana.
Webb, no longer in sight since its encapsulation in the fairing on 17 December, has been closely monitored. The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth.
Ariane 5, standing 53 m high on its mobile launch platform was transported along rails from the final preparation building to the launch zone where final health checks and preparations for liftoff will occur.
This includes filling the propellant tanks of the Ariane 5 core stage with liquid oxygen and liquid hydrogen via lines through the launch table.
Final electrical and software configurations will also occur on the launch pad. Webb will switch to internal battery power about 20 minutes prior to liftoff, and within 15 minutes prior to liftoff the observatory and its launch vehicle will both be fully cleared for flight.
Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace.

Arianespace's Ariane 5 rocket with NASA’s James Webb Space Telescope onboard, is seen at the launch pad, Thursday, Dec. 23, 2021, at Europe’s Spaceport, the Guiana Space Center in Kourou, French Guiana. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Photo Credit: (NASA/Bill Ingalls)
The Ariane 5 launch vehicle which will launch the James Webb Space Telescope was moved to the final assembly building at Europe’s Spaceport in French Guiana on 29 November 2021.
Ariane 5 parts shipped from Europe to French Guiana, have been coming together inside the launch vehicle integration building.
The lower part of the Ariane 5 comprises the cryogenic main core stage (with the Vulcain main engine, oxygen and hydrogen tanks), two solid rocket boosters and the upper composite, including the cryogenic upper stage (with the HM7B engine, oxygen and hydrogen tanks), the vehicle equipment bay – the 'brain' of the launcher, and all supporting structures that will interface with Webb on its adaptor.
A launch table is used to transport the Ariane 5 vehicle between the launch vehicle integration building, the final assembly building and the launch pad.
Webb, now fuelled, will soon be integrated on Ariane 5’s upper stage and then encapsulated inside Ariane 5’s specially adapted fairing.

On Friday 17 December, the Ariane 5 rocket fairing was closed around the James Webb Space Telescope. This protective fairing, or ‘nose cone’, will shield the telescope during liftoff and its journey through the atmosphere on 24 December.
Earlier this week, Webb was placed on top of Ariane 5 and a protective ‘shower curtain’ was put up to avoid any contamination.
On the day of encapsulation in the fairing, a protective cover on top of Webb was removed and the fairing was lowered down over the observatory and locked in place for liftoff.
This was a particularly delicate operation, assisted by a laser guiding system, because the margins between the folded up observatory (4.5 m wide) and the rocket fairing (5.4 m wide) are small.
The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth.
Now that Webb has been securely attached to its Ariane 5 launch vehicle, and enclosed within its protective fairing, mechanical operations involving the observatory at its launch site in French Guiana have formally concluded.
Final electrical and software configurations will occur on the launch pad during the final hours before liftoff. Webb will switch to internal battery power roughly 20 minutes prior to liftoff, and within 15 minutes prior the observatory and its launch vehicle will both be fully cleared for flight.
Ariane 5’s rollout to the launch pad is scheduled to begin Wednesday 22 December, and this is where final health checks and preparations for liftoff will occur.

Last night, an Ariane 5 launcher lifted off from Europe’s Spaceport in French Guiana on its mission to place two telecom satellites, Skynet-5D and Mexsat Bicentenario, into their planned transfer orbits. The satellites were accurately released into their geostationary transfer orbits 27 and 36 minutes after liftoff, respectively.

The James Webb Space Telescope was transferred to the final assembly building at Europe’s Spaceport in French Guiana on 7 December 2021, to meet its Ariane 5 launch vehicle.
Stowed inside a special 23-tonne transport container, Webb was protected and monitored throughout the transfer.
Ariane 5 was already moved to the same building on 29 November. Here, adjustable platforms allow engineers to access the launch vehicle and its payload.
The next steps are to hoist Webb to the upper platform which has been prepared so that Webb can be integrated on Ariane 5’s upper stage and then encapsulated inside Ariane 5’s specially adapted fairing.
Webb is scheduled for launch on 22 December from Europe’s Spaceport. Ground teams have already successfully completed the delicate operation of loading the spacecraft with the propellant it will use to steer itself while in space.
