The Hubble Space Telescope has delivered an amazing near quarter-century of science from all over the universe. Even this year, its delivered results to think about: the shrinking Great Red Spot on Jupiter (see picture below), helping New Horizons hunt for flyby targets after Pluto, and enhancing our view of deep space.

But that didnt come cheap. Four astronaut servicing missions (including one to fix a mirror that was launched with myopia) were required to keep the telescope going since 1990. Hubble has never been more scientifically productive, according to a recent NASA review, but a new article asks if Hubble is destined to die a fiery death when its orbit decays in the next eight to 10 years.

NASA doesnt have any official plans for upgrading the telescope, meaning its hardware will grow old and out-of-date in the coming years, reads the article in Popular Science. Without assistance, Hubble cant maintain its orbit forever, and eventually Earths gravity will pull the telescope to a fiery death.

Thats not to say NASA is going to abandon the cosmos far from it. Besides NASAs other space telescopes, the successor James Webb Space Telescope is planned to launch in 2018 to chart the universe in other wavelengths. But a review from April warns that ceasing operations of Hubble would not be prudent until James Webb is up, running, and doing its own work productively. Thats a narrow window of time considering Hubble is expected to work well until about 2020.

The Hubble Space Telescope senior review panel submitted a report on March that overall praised the observatorys work, and which also talked about its potential longevity. As is, Hubble is expected to work until at least 2020, the review stated. The four science instruments are expected to be more than 85% reliable until 2021, and most critical subsystems should exceed 80% until that same year.

The report urges that experienced hands are kept around as the telescope degrades in the coming years, but points out that Hubble has backups that should keep the observatory as a whole going for a while.

There are no single-point failure modes on Hubble that could take down the entire observatory. It has ample redundancy. Planned mitigations for numerous possible sub-system failures or degraded performance have been developed in advance via the projects Life-Extension Initiatives campaign. Hubble will likely degrade gracefully, with loss or degradation of individual science instrument modes and individual sub-system components.

In NASAs response to the Senior Review for several missions (including Hubble), the agency said that the telescope has been approved (budgetarily speaking) until 2016, when an incremental review will take place. Further in the future, things get murky.
