For all I was privileged to see as an attendee of the Hubble 25th Anniversary NASA Social, the above picture typifies what I learned. When Hubble Space Telescope launched into orbit aboard Space Shuttle Discovery on April 25, 1990, it contained three reel-to-reel tape recorders. Reel-to-reel! The above is one of two that were replaced by solid state drives in subsequent servicing missions. (A solid state drive provides storage on the smartphone you may be reading this on.)
Now, keeping the old reel-to-reel in mind, watch the spectacular video below. It combines Hubble’s observational keenness with digital wizardry to achieve a 3D rendering of a nebula. See how far we’ve come in a quarter century of Hubble observations!
I first watched the above video on Thursday, April 23rd, on a gigantic HD screen at the Newseum in Washington, DC. I and my fellow NASA Social attendees applauded the visual treat. We were among the guests for a televised press conference and image unveiling: Star Cluster Westerlund 2. The image comes from 20,000 year old light emanating from 2 million year old suns.
NASA Administrator Charles Bolden, who piloted the shuttle mission that released Hubble 25 years ago, presided over the press conference. Seen at center in the above photo, he was joined onstage by Hubble Senior Project Scientist Jennifer Wiseman and NASA Associate Administrator John Grunsfeld (like Bolden an astronaut with first-hand Hubble experience). Not seen in the image, but also speaking at the event was Kathy Flanagan, Interim Director of the Space Telescope Science Institute.
Following the press conference, NASA Social attendees were bused out to
Goddard Space Flight Center for behind-the-scenes tours of facilities like the above Space Environment Simulator--a high vacuum cryogenic facility that chugs super-cold liquid nitrogen by the gallon. As was a recurring theme throughout the day, our celebration of Hubble transitioned into discussions about the James Webb Space Telescope which should launch into space in 2018.
There was even some playful smack talk about Hubble versus Webb in the pantheon of observatories. In reality, NASA wants to keep Hubble operational through at least 2020. This would allow Hubble and Webb to observe the deepest regions of space in tandem.
Of my day at NASA Goddard I will say that it was a thrill to see the facilities up close--to observe as dedicated scientists and engineers build and test instruments that must survive in the cold vacuum of space for decades at a time. Much of what launches from Kennedy Space Center in Florida is first made space-worthy in labs at Goddard.

Like Hubble, I've been staring up and out for the last 25 years. I remember one of my high school teachers sheepishly explaining Hubble's early technical snafu as it unfolded. Being a brat at the time, I found it a bit amusing. Yet over the years, as happened for so many of us, the improved telescope refined and expanded my sense of the universe and my place within it. A few years ago, I contributed a photo caption to an article celebrating the final servicing mission of Hubble, published by the Planetary Society.
When I watched the IMAX film Hubble 3D at the Smithsonian Air and Space Museum back in 2010, I confess I was brought to tears by the shuttle launch sequence. So, by way of geeky tendencies, I have a romantic sense of Hubble’s ongoing mission. Thanks to my Goddard visit, I now have been in the same room with Hubble’s early components. The connection feels more tangible than ever before.
