About two weeks ago, Herschel was weighed to record its dry mass before the satellite was fuelled with 256 kg of liquid hydrazine. After switching it on to confirm normal function, engineers integrated the fuelled satellite with the Ariane 5 adapter.

Tests conducted on Planck at Europe's Spaceport in Kourou, French Guiana, have confirmed that the satellite's subsystems work perfectly, and the helium dilution cooler tanks have now been filled. While the final clean-up continues, the solar array has been checked, the satellite has been integrated with its launcher adapter and fuelling is complete.

Herschel’s high-tech cooling system is loaded with helium for the telescope’s upcoming Ariane 5 launch

April 22, 2009

http://www.arianespace.com/news-mission-update/2009/586.asp

The Herschel space telescope for Arianespace’s next Ariane 5 mission literally “chilled out” this week with the loading of liquid helium that will help it gather data on the formation of stars and galaxies.

A total of 2,300 liters of liquid helium will be carried inside a cryostat, keeping the temperature of Herschel’s scientific instrument detectors close to absolute zero (–273ºC).  This will enable the space telescope to provide an unprecedented view of the “cold universe” with observations made in far-infrared and sub-millimeter wavelengths.

The cryostat – which could be described as a “high-tech thermos bottle” – contains the space telescope’s focal plane, where infrared light will be focused from Herschel’s primary and secondary mirrors.

Liquid helium loading for the cryostat is being performed in the S5B hall of the Spaceport’s S5 payload preparation facility.  Work stands were installed around Herschel, allowing the multiple supply bottles to be positioned at the right height for their helium transfer to the space telescope’s cryostat.

Herschel is 7.5 meters tall and 4.5 meters in diameter, and carries the largest telescope mirror ever to be launched into space.   Built for the European Space Agency by a Thales Alenia Space-led industrial team, Herschel will have a liftoff mass of 3,400 kg. 

Accompanying Herschel on the upcoming Ariane 5 mission will be Planck, a 1,900-kg. space observatory that will observe the Big Bang’s relic radiation for a better understanding of the universe’s origin.   Planck also was developed in the framework of a European Space Agency program, and was produced by a Thales Alenia Space-directed industry team.

A launch date announcement for the Herschel/Planck flight is pending while additional checks are performed on the Ariane 5.   This was decided after an anomaly was discovered during tests on a subassembly identical to one equipped on Ariane 5 – which has been assembled at the Spaceport, and is awaiting the integration of its dual space science payload.

The Planck space observatory is integrated on Ariane 5 for Arianespace’s upcoming launch

April 24, 2009

http://www.arianespace.com/news-mission-update/2009/587.asp

 Preparations for Ariane 5’s upcoming mission to explore the universe’s origins have entered their final phase with the startup of payload integration on the heavy-lift launcher.

The Planck observatory was installed atop the launch vehicle’s core stage yesterday, marking a major step in the build-up of Ariane 5’s dual payload “stack.” This 1,950 kg. spacecraft will study relic radiation from the Big Bang, providing new information on the formation of galaxies and how the universe began. 

Planck is riding in the lower position of the payload stack on Ariane 5, and will be situated below the Herschel space telescope, which will be integrated next on the launch vehicle.

Designed to make the most accurate maps ever of the microwave background radiation that fills space, Planck will scan the sky in nine wavelength bands. This information will help determine the universe’s fundamental characteristics, including the overall geometry of space, the density of normal matter and the rate at which the universe is expanding.

Planck carries a telescope with an effective aperture of 1.5 meters, which directs microwave radiation onto the spacecraft’s two instruments. The Low Frequency Instrument’s array of 22 tuned radio receivers will image the sky in three frequencies between 30 GHz. and 70 GHz., while the High Frequency Instrument is to use 52 bolometric detectors that operate at six frequencies between 100 GHz. and 857 GHz.

Both Planck and Herschel will be deployed by Ariane 5 into very elliptical orbits, enabling these spacecraft to follow transfer trajectories for their 1.5 million kilometer voyages to the Sun-Earth system’s second Lagrange point (L2). The two spacecraft were built by Thales Alenia Space-led industrial teams for the European Space Agency’s space science program.

A launch date announcement for this mission – Arianespace’s second of 2009 – is pending while additional checks are performed on the heavy-lift Ariane 5 ECA. The checks were decided after an anomaly was discovered during tests on a subassembly that is identical to equipment already installed on the Ariane 5 at Europe’s Spaceport.

Herschel and Planck to lift off on 14 May
 
28 April 2009

Now that additional checks on the Ariane 5 ECA launcher have been completed, Arianespace and ESA have set the launch date of Herschel and Planck for Thursday 14 May.

In the meantime, the preparation of the two satellites for launch continues flawlessly at Europe’s Spaceport in French Guiana. Herschel and Planck have already been fuelled with hydrazine. Planck’s three-stage active cryogenic cooler, needed to keep the instruments at extremely cold temperatures, has been filled with helium-3 and helium-4. Herschel's cryogenic tanks are also being filled with superfluid helium.

Planck was also integrated with the Ariane 5 launcher, and is now waiting to be covered with the SYLDA element. This structure is needed to both encapsulate Planck during launch and to support the upper passenger – Herschel.

Final integration underway for Ariane 5's May 14 launch with Planck and Herschel
April 29, 2009

http://www.arianespace.com/news-mission-update/2009/588.asp

The payload “stack” build-up for Ariane 5’s second mission of 2009 marked another milestone with the encapsulation of its lower passenger – the Planck space observatory – in the SYLDA dispenser system.
 
SYLDA is a canister-shaped device that enables Ariane 5 to carry its trademark dual satellite payloads, and the dispenser has been positioned over Planck – which was installed atop the Ariane 5’s core stage last week.   

The encapsulation took place inside Ariane 5’s Final Assembly Building at the Spaceport in French Guiana, where the heavy-lift launcher is scheduled for a May 14 liftoff.

With Planck now covered by the dispenser, all is ready for the placement of the Herschel space telescope atop SYLDA, along with the addition of the payload fairing that protects Ariane 5’s two passengers during its ascent through the atmosphere’s dense layers.

During Ariane 5’s launch sequence on May 14, Herschel will be deployed first, followed by the release of Planck.  Both payloads were produced by Thales Alenia Space-led industry teams for the European Space Agency’s space science program.

Planck is designed to map the sky in nine wavelength bands, helping to determine the universe’s fundamental characteristics – including the overall geometry of space, the density of normal matter and the rate at which the universe is expanding.   The observatory carries a telescope with an effective aperture of 1.5 meters, which will direct microwave radiation onto the spacecraft’s low frequency and high frequency instruments.

Herschel will be the largest space telescope ever launched, and was conceived to provide astronomers with their best views of the universe at far-infrared and sub-millimeter wavelengths.  Data gathered with Herschel’s 3.5-meter-diameter mirror will be used to study the formation of stars and galaxies, and to investigate the relationship between the two.

After being lofted by Ariane 5, both Planck and Herschel will follow transfer trajectories for their 1.5 million-kilometer voyages to the Sun-Earth system’s second Lagrange point (L2).

Are there any NSJF members planning to attend this launch? Or has somebody any idea about cheap accomodation around kourou?

I'm in Guyana (the formerly british part) right now and might be able to make it to this launch.

The main hotel in Kourou is the "hôtel des Roches". You should book your room right now, because many people want to sleep there when there is a launch !

An other hotel is "Ariatel".
http://www.accorhotels.com/gb/hotel-1592-mercure-kourou-ariatel/index.shtml
This one is probably cheaper than "hôtel des Roches". It is important to notice that after each launch, there is a big party organized by Arianespace in this hotel ! :-)

I don't think there is another.

Nota : if you are not vaccined against yellow fever, you won't be allowed to enter French Guiana.

I happen to know that all hotel rooms in Kourou are taken during the middle of next week. You'll probably need to stay in Cayenne - it's an 1hour car ride from Kourou.

Europe's Herschel space telescope joins its Planck observatory co-passenger on the Ariane 5 launcher

http://www.arianespace.com/news-mission-update/2009/589.asp

May 4, 2009

The second of two passengers to study the cold depths of space has been integrated on the Ariane 5 launcher, marking a major new step in preparations for Arianespace’s upcoming heavy-lift mission.
 
During activity performed in Ariane 5’s Final Assembly Building at the Spaceport, Herschel was installed in the upper position of the launcher’s payload “stack.”  It is mated atop the SYLDA payload dispenser system, which previously was installed over the mission’s lower passenger – the Planck observatory.

With Herschel and Planck now integrated on Ariane 5, preparations for Arianespace’s May 14 launch from French Guiana move into their final phase – with several peculiarities for the pioneering dual space science mission.

This includes a “top-up” of Herschel’s cryostat cooling system with liquid helium, which is now underway and will continue into next weekend.  The cryostat will keep the temperature of Herschel’s scientific instrument detectors close to absolute zero (–273ºC), enabling the space telescope to provide an unprecedented view of the “cold universe” during observations made in far-infrared and sub-millimeter wavelengths.

Members of the Herschel team initially filled the cryostat with liquid helium during operations in April, which were performed in the Spaceport’s S5 payload preparation facility.  The current top-up serves several purposes: ensuring the liquid helium is maintained at a low temperature, replacing any loss that occurred since the initial loading, and filling any volume created when vacuum is applied to the cryostat.

Once the liquid helium top-up is completed, the Herschel/Planck stack will be encapsulated inside Ariane 5’s protective fairing, completing the launch vehicle’s integration.   

Herschel will be the largest space telescope ever launched, with its 3.5-meter diameter mirror providing astronomers a better understanding of the formation of stars and galaxies. 

Planck also will study the cold cosmos.  The data from its telescope, which has an effective aperture of 1.5 meters, will help determine the universe’s fundamental characteristics – including the rate at which it is expanding.   

Both Planck and Herschel were built by Thales Alenia Space-led industry teams for the European Space Agency.  After their launch by Ariane 5, the two spacecraft will follow trajectories for 1.5 million-kilometer voyages to the Sun-Earth system’s second Lagrange point (L2).  Planck’s mass at liftoff will be approximately 1,920 kg., while Herschel will weigh about 3,400 kg. at launch.
