A few kilograms of DNA could theoretically store all of humanity's data, but there are practical challenges to overcome.

Abstract
Digital information is accumulating at an astounding rate, straining our ability to store and archive it. DNA is among the most dense and stable information media known. The development of new technologies in both DNA synthesis and sequencing make DNA an increasingly feasible digital storage medium. We developed a strategy to encode arbitrary digital information in DNA, wrote a 5.27-megabit book using DNA microchips, and read the book by using next-generation DNA sequencing.

The Hubble Space Telescope is currently reported to be in "safe mode" due to the failure of another orientation gyroscope. Getting an earlier failed & 'sticky' gyroscope back up working seems to be the plan. :(
Story @ space.com

More info. @ NASA link
...
If the outcome indicates that the gyro is not usable, Hubble will resume science operations in an already defined “reduced-gyro” mode that uses only one gyro. While reduced-gyro mode offers less sky coverage at any particular time, there is relatively limited impact on the overall scientific capabilities.

Phew!

Thanks, newolder.

Wow, (limited) scientific capability on only on gyro? Did not know that was possible.

Could they get to the Hubble without the shuttle??
