Three beautiful lines of telemetry:
78: Motor_Current_Position =67029 (50%)
79: Camera_0_onOff=1 (on)
80: Camera_1_onOff=1 (on)

--
which I take to mean the sail is at least 50% extended, and the cameras are taking pics of the process as scheduled

Planetary article; the sail has deployed.
Some problems with images, but they are working on it

LightSail image update: team initiated re-transfer of pics from onboard cams to flight software. Will try downlink again at 11:02 PDT.

Emily Lakdawalla has tweeted a couple of hours ago the first look at the deployed sail! Although the image has some corrupted areas, it seems clear it has deployed successfully:

I've been working on descrambling the partial pic of #LightSail....just a few little sail bits I can't figure out

See also Mike Patton's post in the Planetary Society's website: http://www.planetary.org/blogs/jason-davis/2015/20150608-sails-in-space.html - the image is expected to be completely downloaded tomorrow morning. If (as it appears) the sail is not fully tensioned, the booms will be commanded in the next few days to achieve it, as the orbit is already decaying fast.

Picture of full sail is up on facebook!

Possibly not deployed fully, edges look bowed inwards between the poles.

mtakala24 · « **Reply #275 on:** 06/10/2015 11:19 am »

They haven't done the final tensioning prior to those images.

CROWDSOURCE CALL: Can you help compile a #LightSail image? This JPG is from other camera, but loads as blank image. http://planetary.s3.amazonaws.com/assets/z-misc/2015/P01_15878x16388_176-1_T47_3_26_D2_20_0.out.jpg …

The #LightSail image I posted has first 24 bytes removed (metadata), and this header attached: http://planetary.s3.amazonaws.com/assets/z-misc/2015/header.txt …

Finally, here's the original-original #LightSail image, with metadata intact and no headers attached: http://planetary.s3.amazonaws.com/assets/z-misc/2015/1.jpg … Thanks!

New article with more speculation as to why we might not have seen this particular X-37B.

How do you move a rocket?

Ted Molczan's June 14, 04:30 UTC report on SeeSat-L reports LightSail-A will re-enter today, June 14, near 20:39 h UTC.

Uncertainty is +/- 4 hours.
