NASA SDO - Roll, Roll, Rolling (April 3, 2013)

Показать описание
The life of a Sun observing spacecraft is not boring at all. On April 3, 2013 the SDO team ran a HMI roll maneuver from 0550-1230 UTC (00:40-7:30 ET). The entire SDO spacecraft body was spun around so that HMI can verify its operation and measure some calibration data.

HMI is the Helioseismic and Magnetic Imager instrument and extends the capabilities of the SOHO/MDI instrument with continual full-disk coverage at higher spatial resolution and new vector magnetogram capabilities. In other words, HMI lets us learn more about sunspots and lets scientists see inside the Sun.

The first two black and white segments of this movie were taken by the HMI instrument.

As a radio ham I find SDO video's a good source of propagation information. I hope this service stays up and running for a very long time.

Our latest eye on the Sun - providing us with a lot of new insights into our Star.

This is just too cool for though I had to use a few to comment.

We were debating but did not want to go overboard...

I love this. Then again I have an SDO sticker on my truck so I like it all. :)

I half-expected the logo at the end to roll too.

It's a comic song I chose. I thought it was a great fit.

Well...yes. Just not that fast, and not around that axis.
