Herschel's daring test: a glimpse of things to come

Herschel's test view of M51
Herschel's test view of M51

Herschel opened its 'eyes' on 14 June and the Photoconductor Array Camera and Spectrometer obtained images of M51, 'the whirlpool galaxy' for a first test observation. Scientists obtained images in three colours which clearly demonstrate the superiority of Herschel, the largest infrared space telescope ever flown.
This image shows the famous 'whirlpool galaxy', first observed by Charles Messier in 1773, who provided the designation Messier 51 (M51). This spiral galaxy lies relatively nearby, about 35 million light-years away, in the constellation Canes Venatici. M51 was the first galaxy discovered to harbour a spiral structure.

Herschel telescope 'opens eyes'
Europe's new billion-euro Herschel space observatory opens a hatch allowing its instruments to see the cosmos for the first time.

At around 10:54 UTC this morning the Herschel cryocover was commanded to open by manual commanding from the MOC here at ESOC.
The command was executed nominally, there is telemetry indicating that the cover reached the open position, the shaking of the spacecraft caused by the opening was seen on the gyros and the phase separator, and the temperatures at L0 and L1 slightly changed.
All of this is consistent with what you would expect from a successful cryocover opening. The final positive confirmation will come from a measurement of the optical background as seen by the PACS instrument which is underway.

Lid Release on the Herschel Space Observatory


We've now been told that the cryocover will be opening on Sunday, with first light data from the Herschel instruments coming down to us on Monday.
If the cryocover doesn't open then that's it - no science. It is what they call a 'single point failure mode'. However, the cover's mechanism has been extensively tested so it should work.

SYLDA 5 payload dispenser

The SYLDA 5 payload dispenser's deployment is imaged during Ariane 5's most recent mission success
A key element of Ariane 5's dual payload deployment system was imaged in a unique series of in-flight photos taken by one of its two European-built passengers during the Arianespace launcher's successful deep-space mission on May 14.
The SYLDA 5 dispenser was captured by the Herschel space telescope's Visual Monitoring Camera at an altitude of more than 1,000 km. above Africa.
SYLDA 5 serves as the central element in Ariane 5's dual payload "stack."  On Arianespace's May 14 mission, the 3,400-kg. Herschel spacecraft rode as the upper payload.  It was installed atop the SYLDA 5, which was positioned over the launcher's lower payload - the 1,920-kg. Planck observatory.

An updated trajectory is now available for Herschel.  The following identifications apply to the provisionally-designated HPOx objects:

HPO1 = 2009-026D
HPO2 = Herschel
HPO3 = 2009-026C
HPO4 = 2009-026E
HPO5 = 2009-026F

Herschel and Planck commissioning has begun
After a perfect injection by the Ariane 5 launcher on 14 May, the critical Launch and Early Orbit Phase (LEOP) for Herschel and Planck has started to wind down, while commissioning of the scientific instruments and subsystems on both spacecraft has begun.
Herschel and Planck are functioning nominally and are now en route to their final orbits around the second Lagrange point of the Sun-Earth system (L2), a point in space 1.5 million kms from Earth on the night-side.

Mit einem Teleskop macht man Bilder vom Himmel, das ist allgemein bekannt. Dass in einem solchen Bild zwei weitere Teleskope auftauchen, nun gut, das mag noch angehen. Wenn aber die zwei abgebildeten Teleskope in bereits 100000 km Entfernung auf dem Weg zu ihrer Zielbahn um den L2-Punkt 1.5 Millionen Kilometer "hinter" der Erde aufgenommen wurden, ist das schon etwas Besonderes.

Two more objects are discovered flying in formation with the ESA space telescopes Herschel and Planck. It is somewhat unclear which objects are Herschel and Planck and even more what the other two objects are.

Ed ~ this is actually the ARIANE 5 rocket body, and Debris (ie SYLDA)
