The Japanese space agency JAXA have launched their M-V Launch Vehicle (Flight #8) with the infrared astronomy satellite ASTRO-F, from the Uchinoura Space Center tonight.
JAXA had a successful launch at 21:28 UTC (4:28pm Eastern US), following yesterday’s scrub with just 15 minutes remaining in the count, due to rain over the space center.

The successful launch makes it two launches in just over three days for JAXA, hot on the heels of Saturday’s H-IIA Launch Vehicle (H-IIA F9) from the Tanegashima Space Center, taking the Multi-functional Transport Satellite 2 (MTSAT-2) into a geostationary orbit.
ASTRO-F has a 70 cm telescope,which is cooled down to -270 degree with liquid helium in order to suppress unwanted infrared radiation from the telescope itself. The spacecraft will be entered into a polar orbit along the twilight zone.
IRAS (Infrared Astronomical Satellite, launched in 1983 by the United Kingdom, the United States, and the Netherlands) carried out the first all-sky survey at infrared wavelengths and made a huge impact on astronomy.
The ASTRO-F mission is an ambitious plan to make an all-sky survey with much better sensitivity, spatial resolution and wider wavelength coverage than IRAS.
