4. Hubble Memorable Moments: Comet Impact

In July 1994, the Hubble Space Telescope was poised to use its newly fixed optics to observe one of the most impressive astronomical events of the century - the 21 fragments of Comet Shoemaker-Levy 9 impacting Jupiter. But these observations almost didn’t happen.

In celebration of the 25 years since the Hubble Space Telescope's April 1990 launch, NASA's Goddard Space Flight Center recalls intense moments throughout Hubble's history that were memorable for Goddard's engineers and flight operators.

3. Hubble Memorable Moments: Tinkertoy Solution

The Hubble Space Telescope got off to a rocky start when shortly after its April, 1990 deployment, operators found that its high-gain antenna was mysteriously stuck. Hubble team members recall that intense week and how they ultimately solved the antenna problem in this third installment of Hubble Memorable Moments: Tinkertoy Solution.

2. Hubble Memorable Moments: Brute Force

In this second video of NASA's Hubble Memorable Moments series celebrating Hubble's 25 years, the team scrambles to work out an unusual solution to a problem encountered during an instrument repair.

The Space Telescope Imaging Spectrograph, or STIS, was installed on Hubble during Servicing Mission 2 in 1997. The versatile instrument was heavily used until a power supply failure in 2004. The Hubble team spent years preparing for a complex repair task in 2009 on the final servicing mission. But no matter how prepared you are, there is always the possibility of an unexpected obstacle.

1. Hubble Memorable Moments: Powering Down

In this first video of NASA's Hubble Memorable Moments series celebrating Hubble's 25 years, the telescope must be completely powered off to replace Hubble's heart.

In 1999, engineers at NASA's Goddard Space Flight Center discovered that there was a problem with Hubble's Power Control Unit. Hubble team members came up with a plan to replace the unit on Servicing Mission 3B. On March 6, 2002, the day came to put that plan into action. What could go wrong?
