IKAROS successfully deploys sail!
The Small Solar Power Sail Demonstrator "IKAROS" launched by the H-IIA F17 began to deploy its sail on June 3 (Japan Standard Time, JST,) and on June 10 (JST,) about 7.7 million km from the Earth, JAXA confirmed the proper extension of the sail and power generation by the thin film solar cells.
We will continue to measure the power generation status of the cells attached to the sail, and will verify acceleration by the cells and orbit control by their acceleration.

This technology will help us (human being) travel to Jupiter, Saturn and planets beyond the solar system. 🙂
 
Congratulations to JAXA! Impressive achievement. I saw the solar sail concept on a Disney animated science program a loooong, looong time ago. I'm happy to learn that Japan was the first to implement it. More impressive, though, are the ion engines on Hayabusa. According to that same Disney program, an ion engine is theoretically able to reach sub-light speed!

Yes, ion engine must be a driving force for future space adventure, enabling us to make Space Battleship Yamato !!

IKAROS Update: Acceleration by solar sail confirmed

The small solar power sail demonstrator "IKAROS," which successfully deployed its solar sail, was confirmed to accelerate by solar sail receiving solar pressure.
This proved that the IKAROS has generated the biggest acceleration through photon during interplanetary flight in history. JAXA | AKATSUKI Special Site

Sailing by solar pressure is exciting. JAXA said driving force by solar pressure is 1.12m N (Newton), which is nearly equal to Gravity to the object of 0.114 gram on earth.
 
IKAROS Update: Gamma-Ray Burst Observed
The Japan Aerospace Exploration Agency (JAXA) said Wednesday that Ikaros, its small solar-powered "space yacht," has observed a gamma-ray burst resulting from the explosion of a massive star.

JAXA will try to measure the polarization of gamma rays created by the event. If successful, it would be the first to do so. The agency said the rays captured by Ikaros are from a star about 13 billion light years away and 30 times more massive than the sun. JAXA researchers hope the observation results will shed light on the mechanism of gamma-ray bursts.

A Kanazawa University team led by Professor Toshio Murakami developed the ray-detection device, known as the Gamma-Ray Burst Polarimeter, or GAP.

Great news. A movie about JAXA's future is coming soon to a theater near me (and maybe you, too).
