is this name derived from the name of the spacecraft 'icarus' in the british space film Sunshine??
According to Space.com, Ikaros is the first solar said to "fly on an interstellar mission."
Why was it reported this way... will Ikaros eventually leave the solar system? Or is the Space.com article simply in error? 71.219.229.95 ( talk) 03:11, 4 August 2010 (UTC)
According to this page http://www.isas.jaxa.jp/home/IKAROS-blog/?blogid=12 IKAROS reached Venus on December 8, 2010. —Preceding unsigned comment added by 167.6.247.203 ( talk) 16:50, 13 December 2010 (UTC)
"JAXA confirmed that IKAROS is being accelerated by its solar sail." How much? What is the delta-V that is due to the sail (as opposed to the Sun's gravity)? Mcswell ( talk) 19:34, 8 February 2011 (UTC)
At what speed is IKAROS traveling?
And how much of this speed comes from the solar sail versus the original speed before it left the other spacecraft?
Is it always accelerating? And if so, by how much? And how fast is it expected to travel in the future?

P.S. The English on the Official website isn't very good. Can anyone translate so we can add more material to the Wikipedia article?
Thanks for any help,

Is 100 m/s miles per second or meters per second?
Appreciatively,

Using the blog to estimate speed
I did a quick calculation based on two blog entries:
On Nov 22, the distance from Earth was reported as 206480857 km. On Dec 3, the distance from Earth was reported as 216897056 km.
That's a distance of 10416199 km [7] in approximately 11 days, or an equivalent speed of 10.9598053 km per second [8].
Of course, IKAROS is not travelling directly away from Earth, so some trigonometry could be used to determine how much faster than this IKAROS is going, but at these distances and with so much error in the time component (exactly 11 days?) it's probably not worth it for this rough estimate.
For comparison, Voyager 1 is traveling at about 17 km/s. [9]

Is IKAROS already broken? I can't find any news about IKAROS after venus flyby at Dec, 2010. I don't think this is normal for IKAROS because which should have more flyby to nearby planet soon. — Preceding unsigned comment added by 219.73.89.188 ( talk) 13:50, 30 March 2012 (UTC)
Can anybody supply information about the orbit of IKAROS? Obviously the solar sail has an effect on the orbit of the spacecraft, so it is more than gravitiy ("Newton") at work here. But are there estimatess for perihelion, aphelion and orbital period of IKAROS (2010-020E)? And if anybody could find the "initial" trajectory (without the effect of the solar sail), the delta-v it has collected (and so on) this would be great.

Please don't give meters per second. Only scientists or engineers can understand that. How many kilometers per hour, or miles per hour? Also, where is it now? Many thanks for any help. 2602:306:BDA0:97A0:466D:57FF:FE90:AC45 ( talk) 08:07, 19 May 2014 (UTC)

So, where is it?
Is it orbiting anything or just floating around in space?
Any communications since 2015?
For such an ambitious project, am rather surprised at lack of post-2015 info and follow-up/through.
Even the current locations of the extremely old Voyager spacecrafts are known and there are still the occasional news releases about them. 2600:8800:785:9400:C23F:D5FF:FEC4:D51D ( talk) 03:22, 8 December 2020 (UTC)
