Dear GLIMS colleagues,</div>
<div class="elementToProof" style="font-family: Arial, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
May 11 was maybe a "Dewey Beats Truman" moment of a premature death and funeral announcement. On May 15, it was reported (below) that ASTER VNIR is operable again. Hurray! Frank Paul asked me if the electrical problem that caused the shutdown was due, perhaps,
to the solar storm. I don't know the answer to that question, but the coincidence of timing is interesting. I have been waiting for updates so that I don't keep you going like a yo-yo, but there has been nothing since May 15, so I presume we are still operating
normally since then, after the few days shut down. Fingers crossed!</div>

<div style="line-break:after-white-space"><span style="font-size:14px">It appears the Goddard team has a temporary workaround to keep VNIR channel active by maintaining battery stability using other load shedding . So until we get another update stating VNIR
deactivation is definitely necessary, we’ll continue to collect data as normal. Still need some clarification from Japan and Goddard regarding the recent acquisitions but it appears they were collected as normally set for the existing STARs. We are not
out of the woods yet, but still on the right path.</span></div>

Thanks for your message. I remember, soon after I arrived at USGS after getting my PhD, and I was all about Mars, Mars, Mars (Mars glaciers and ancient glaciation especially), you tried to recruit me to help with ASTER for mapping of the world's glaciers. I
was too thrilled about Mars, and a bit of Venus, and icy satellites of the giant planets, and was (compared to my grad student wallet) floating in NASA grant money, and I declined. You appealed a while later another time. I declined. You made one last appeal.
My kids at the time were 10 and 12 and 20 (or 9, 11, and 19) years old. You said, "Jeff, when your kids are done with college, ASTER is likely to still be operating. Think again before you say "no."" I did think, and I said yes. I'd help, but only for 1/3
full-time-equivalent. In fact, the youngest of my kids is now 39 years old, and she has three of her own kids ages 4, 13, and 19. </div>

So, yes, poor ASTER, but before VNIR passed, I heard her whisper, "I've lived a good and productive life, and I am way older than any orbital instrument is designed to live, I've lived two dog lives; like with old dogs, there is a time. My time is coming."
True for all of us. Thank you, Hugh, for asking that third time. Life would have been easier if I had agreed to full time, but I am so pleased that I had the opportunity to work on GLIMS and related matters, and work with you. It was a genius idea you had.
It was harder than any of us imagined at first, but we did it, and one good thing led to another. </div>
