The ASTRO-H launch has been rescheduled by the Japanese space agency JAXA to take place on Wednesday, 17th of February at 9:45 European Time. After the cancellation last Friday, SRON will again organize an event with talks on the importance of the mission and a livestream to witness the launch at SRON.Invited guests and the media are welcome to join SRON from 9:15 onwards that day. Live broadcasting will start from around 9:25 onwards and be shown at SRON. Again, it cannot be ruled out that due to weather conditions the launch will be re-scheduled at a late stage.
ASTRO-H will use observations of cosmic X-rays to study collapsing material in the vicinity of black holes, turbulences in clusters of galaxies, the shockwaves caused by supernova explosions and large-scale structures in the universe. Dark matter and the acceleration of cosmic particles to high energies shall also be investigated by the mission.
SRON has developed a filter wheel for ASTRO-H’s Soft X-ray Spectrometer (together with the University of Geneva) and the onboard calibration source. The filter wheel includes a set of filters which can be used to filter the light of strong X-ray sources and thus optimizes the science return . The onboard calibration source allows continuous corrections for small fluctuations in the energy scale of the imaging spectrometer, which will have an unprecedented spectral resolution (R=1000).
The event at SRON will consist of two parts:
> 09.15 10.30: Livestream of the launch which takes place in Japan (Tanegashima Space Center)
> 11.00 12.00: Talks by SRON scientists: Overview of the ASTRO-H mission, SRON's hardware contributions and the expected breakthrough science
