Hubble’s main camera stops working

31.01.2007
On Saturday 27 January, Hubble’s main camera, the Advanced Camera for Surveys (ACS), stopped working. Until a solution, at least in part, can be found, Hubble will be returned to work with the remaining instruments.

On Saturday 27 January 2007 at 13:34 CET the NASA/ESA Hubble Space Telescope entered into a protective "safemode" condition, most likely triggered by a short circuit in Hubble’s main instrument the Advanced Camera for Surveys (ACS). ACS had been running since June 2006 on its secondary backup electrical system.

NASA has full responsibility for the mission operations of Hubble. Accordingly, NASA has set up an Anomaly Review Board. This will investigate whether ACS can be returned to using the primary electrical system enabling one of its parts, the Solar Blind Channel, to return to operation. However, at this time, it is expected that the main part of ACS will most likely not be restored.

Another Hubble Servicing Mission (SM4) has been scheduled for “not earlier than May 2008” by NASA. Options for repairing the ACS camera during this mission are being investigated.

In the meantime, Hubble will be returned to work again with the other available instruments onboard: the Near Infrared Camera and Multi-object Spectrometer (NICMOS), the Wide Field and Planetary Camera 2 (WFPC2) and the Fine Guidance Sensors (FGS’es).

A call to the astronomers using Hubble is being issued, urging them to re-plan their upcoming observing programmes to take the new situation into account. The deadline for these changed proposals for the present observing cycle, Cycle 16 is 9 February 2007. Out of a total of 750 proposals for the cycle, 500 requested use of the ACS camera (2/3).

“ACS took over from WFPC2 as Hubble’s “workhorse” at the last Servicing Mission in 2002. Although we are taking a step back, it is far from “game over” for Hubble”, says ESA Hubble scientist Bob Fosbury.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
