Launch of Japanese X-ray satellite rescheduled for Wednesday


The Japan Aerospace Exploration Agency and Mitsubishi Heavy Industries Ltd. said they will reattempt the launch of an H-IIA rocket carrying the X-ray astronomy satellite ASTRO-H on Wednesday afternoon.

A planned launch last Friday was scrubbed when bad weather was forecast.

The H-IIA Launch Vehicle No. 30 will lift off from the Tanegashima Space Center in Kagoshima Prefecture at 5:45 p.m. Wednesday, JAXA and Mitsubishi Heavy said Sunday. The launch window will remain open for only 15 minutes.

The weather will remain a factor, and the launch could be postponed again, they said.

The ASTRO-H satellite is designed to observe clusters of galaxies and debris from supernova explosions to help understand cosmic evolution and the structure of the universe.
