Launch Coverage Sponsored by ATK:

The Advanced Land Observing Satellite-2 (ALOS-2) is follow-on mission from the "DAICHI", which contributed to cartography, regional observation, disaster monitoring, and resource surveys. ALOS-2 will succeed this mission with enhanced capabilities.

Specifically, JAXA is conducting research and development activities to improve wide and high-resolution observation technologies developed for DAICHI in order to further fulfill social needs.

These social needs include:

1) Disaster monitoring of damage areas, both in cosiderable detail, and when these areas may be large
2) Continuous updating of data archives related to national land and infrastructure information
3) Effective monitoring of cultivated areas
4) Global monitoring of tropical rain forests to identify carbon sinks.

The state-of-the-art L-band Synthetic Aperture Radar (PALSAR-2) aboard ALOS-2, which is an active microwave radar using the 1.2GHz frequency range, will, in responding to society's needs, have enhanced performance compared to DAICHI/PALSAR. The PALSAR-2 is capable of observing day and night, and in all weather conditions.

PALSAR-2 impulse response evaluation under vacuum environment

From March 5 to 9, JAXA conducted impulse response evaluation of the Phased Array type L-band Synthetic Aperture Radar (PALSAR-2) aboard Advanced Land Observing Satellite-2 (ALOS-2) under vacuum environment in 6-Meter-Diameter Radiometer Space Chamber Building at the Tsukuba Space Center.

The impulse response evaluation under vacuum environment is to verify the PALSAR-2's performance and functions in a vacuum environment that is close to that in space.

PALSAR-2 is additionally installed with a new observation function called“spotlight mode.” Thus its resolution target is one to three meters, which is far better than its predecessor ALOS's PALSAR, whose resolution is about 10 meters. Also, the PALSAR-2 can enlarge its observation area by about three times so that it can quickly provide data with higher accuracy and increase observation frequency.

Any updates on this spacecraft? This is supposed to be launched in December 2013 (is there a more precise date available?) and I don't see any updates on the English project page since almost a year ago.....

No recent update on the launch date, but at least the mission sticker has been revealed yesterday

Hey,
The launch is subject to changes ? Or it's going to be as planned (dec2013) ?
Also, any idea how much time the satellite is going to take after launch until the data is approachable ?

Galactic Penguin SST · « **Reply #5 on:** 10/18/2013 06:25 am »

Any updates? Does the spacecraft have any problems during testing?

No information.
Japanese Launch date information is hardly available untill official date is setting.

Japanese news sources are now reporting a launch date of May 24 - possibly ~03:00 UTC given the sun-synchronous orbit it is heading to has a LTDN of 12:00.

And now confirmed by JAXA - launch window is 03:05 - 03:20 UTC.

ALOS-2 may ends up with a defence-related role (read maritime ship tracking) as well: http://aviationweek.com/space/l-band-sar-satellite-may-help-jaxa-s-new-military-job

Even more interesting:

“We have established a new business promotion center . . . to support industry, which does not necessarily work on space activities in the past,” Okumura says. “In case they wish to utilize space as a place for their experiments or business, we support their activities.”

"Japan is also developing a new launch vehicle, designated H-X or H-III, powered by a new version of the LE-7 main engine, with a first flight scheduled in 2020. It is intended to help Japan break into the commercial launch services market long denied it by the high cost of flying on earlier H-class launch vehicles; Okumura concedes it will be difficult to compete with low-cost launchers such as the SpaceX Falcon 9"

Press kits for the satellite's mission (alas, in Japanese.....when do I have time to start learning it huh?

) - JAXA might want to try look at how other space agencies put their international PR in their Earth observation fleets (see the PR work in English for Sentinel-1A of ESA or SMAP for NASA for instance)
