2011/Jan/19
The observation phase of SMILES terminated. The conclusion of the failure investigation about submillimeter-wave local oscillator was reported. (more)
18/Nov/2010
The quality of the research products processed in NICT and the user interface of the products download system were reviewed by members in NICT and SMILES Science Team.
2010/May/12
The cause of the discontinuance of the SMILES observation at 08:59:55 of 21th April 2010 (UT) was identified as a failure of submillimeter-wave local oscillator. (more)
2010/Apr/23 (JST)
The observation of SMILES is discontinued from 08:59:55 of 21th April 2010 (UT) because one of components in submillimeter-wave receiver turned to the stand-by mode.
2010/Feb/09 (JST)
International SMILES science team meeting will be held on 1-3 March.
2009/Dec/09 (JST)
2009/Nov/06 (JST)
SMILES instrument has started the operational observation since Nov. 06 2009.
2009/Oct/21 (JST)
The SMILES instrument is working well. Observation is basically performing continuously. SMILES will start the operational observation from around 28 October.
2009/Oct/20 (JST)
The initial data was released to the media on 12 October 2009. SMILES press release (Japanese)
2009/Oct/12 (JST)
The initial/test atmospheric observation started on 12 October.
2009/Oct/10 (JST)
The first atmospheric spectrum was taken. Beautiful spectrum observed with Tsys less than 500K and with no standing wave.
2009/Oct/08 (JST)
Cold Load, 2.7K cosmic background radiation, observed with SMILES receiver system for the confirmation of the system. Difference of the brightness temperature measured was less than 0.2K during one/two hours (Stable!). It was confirmed that the solar paddles disturb the SMILES-line-of-sight during observation. We will start manual atmospheric observation from 10 October 2009.
2009/Oct/06 (JST)
SIS mixer system (SIS + LO) are under checking.
2009/Oct/05 (JST)
Antenna driving system was confirmed. Orbit and position data were confirmed. Calibration hot load worked.
2009/Oct/02 (JST)
SIS mixers was confirmed the superconductive status. Submillimeter-wave local oscillator was confirmed. AOS diode laser was confirmed.
2009/Sep/30 (JST)
Star tracker was checked out. Data from STT was transported to JAXA/TKSC without any problem.
2009/Sep/28 12:00 (JST)
Temperature of SMILES receiever reached to 4.1K
2009/Sep/25 09:27 (JST)
SMILES was powered on.
2009/Sep/18 07:26 (JST)
SMILES on HTV arrived at the ISS. SMILES will be installed at JEM/EF by manipulation of robotic arms in next one week.
2009/Sep/11 02:01:46 (JST)
SMILES was launced via HTV/H-IIB from Tanegashima Space Center, JAXA.
