How to Get Time on the Hubble Space Telescope

In contrast with other space telescopes, the Hubble is open for public use if in accordance with their rules and regulations for usage. Updated: Spring 2023 Each year more than 1,000 proposals are reviewed, and approximately 200 are selected. You would need to make contact with Space Telescope Science Institute (STScI) in Baltimore, MD. Anyone on the globe can fairly apply for the usage of this space telescope, and there is an extreme competition in securing a slot of using it. One main reason for the permission of its usage, if the observations needed cannot be accomplished by any ground telescopes. There is always a yearly proposal for the usage of the Hubble telescope. Likewise, these proposals are subdivided into various categories such as black holes, the formation of stars, celestial objects in the solar system, and more. Further, the observing time of a telescope is typically measured by counting the orbits needed for a vivid observation. How Do We Make Contact With STScl?

Before contacting them, it's a good idea to review their website and the available resources, as many common questions are already addressed there. What Is The Process For Signing Up? Renting time on the Hubble Space Telescope is not a straightforward process, as the telescope is primarily used for scientific research purposes. However, if you are a researcher or affiliated with an educational or research institution, you can apply for observing time through a proposal. Here's how you can go about it: Check the proposal cycle: The Space Telescope Science Institute (STScI) operates the Hubble Space Telescope and solicits observing proposals once a year. Visit the STScI website (https://www.stsci.edu) to find information about the latest Call for Proposals and the deadlines for submission. Read the Call for Proposals: The Call for Proposals document will provide detailed information about the telescope's capabilities, available instruments, and the requirements for a successful proposal. Be sure to familiarize yourself with the guidelines and the evaluation criteria. Develop your proposal: Create a clear, concise, and scientifically sound proposal detailing your research objectives, why you need to use the Hubble Space Telescope, and the expected outcomes of your observations. Ensure that you include a comprehensive observing plan with all the required technical details. Register and use the Astronomer's Proposal Tool (APT): To submit your proposal, you will need to use the APT software provided by STScI. Download and install the software on your computer, then register for an account to access the submission system. Use the APT to prepare and validate your proposal. Submit your proposal: After preparing your proposal using the APT, submit it through the online system before the specified deadline. Late submissions are generally not accepted. Await review: The Time Allocation Committee (TAC) at STScI will evaluate the submitted proposals, and those that are highly ranked will be granted observing time on the Hubble Space Telescope. Notifications of the outcome are typically sent a few months after the submission deadline. Keep in mind that competition for observing time on the Hubble Space Telescope is intense, and only a fraction of submitted proposals are successful. It may take several attempts and revisions to secure time on the telescope, so be prepared for a rigorous and competitive process. Types of Proposals for Using the Hubble Here are the different types of proposals for using the said telescope. General Observer (GO): These proposals mostly encompass casual observations of planets, stars, and galaxies. Snapshot Observations: The telescope time allotted for this proposal is 45 minutes or less. These images are used to complete a schedule of telescope time, which is not viable for a general observer proposal. Target Opportunity Proposal: These proposals are scheduled for viewing astronomical phenomenon specific for a certain timeframe or cycle. This can be a discovery of a new planet, star, or comet. Director’s Discretionary Time: In this proposal, the director of the Space Telescope Science Institute (STScl) provides a maximum of ten percent of the total observation time. This proposal is mostly given on unprecedented phenomena like a supernova. All these proposals are yearly evaluated and screened by the Time Allocation Committee (TAC). Likewise, these proposals are also grouped according to similar categories such as active galaxies, stellar physics, and more. The final approval for which proposals are permitted is done by the director of STScl. Where Can You Find Hubble’s Images There are several websites where you can view the images captured by the Hubble Space Telescope. Avid Hubble fans, aspiring astronomers and other learners can definitely make the most out of these sites. Majority of these sites grouped their collection of images into specific categories for easier browsing. These images can be grouped into exoplanets, galaxies, illustrations, nebulae, black hole, solar systems, star clusters, and stars. Furthermore, they also feature exciting videos about star observations and information about the Hubble. To have a quick view for some of these websites, here are among some of the more popular sites visited for Hubble Images: Hubble Space Telescope ESA Top 100 Image: ESA/Hubble Space Telescope Live Hubble Site: NASA When Will the Hubble Space Telescope Die The Hubble space telescope has contributed to humanity with new discoveries and allowing further study of the universe and cosmos. It has been orbiting the Earth and returning beautiful images for twenty-nine years since it was launched in 1990. The Hubble is expected to last until the middle of 2020 at full functionality. The extended anticipated life of the famous space telescope is highly attributed to the successful five service missions done by astronauts during 1993 and 2009. Thomas Brown, Head of the Hubble Mission, said to Space.com that the latest report on the overall status of the Hubble’s system will be operating at above eighty percent until 2025. What Can Possibly Go Wrong with Hubble The magnificent machine is not immortal, and there will come the point where it terminates its operation. The space telescope has three guidance systems maintaining its proper functioning. However, with the presence of high levels of radiation, these sensors are gradually degraded over time. Aside from that, the risk of a malfunction in its communication system poses a great factor for stopping its operation. There were six gyroscopic actuators built into the space telescope, it has been down to two functioning gyros but typically only needs two gyros to operate the telescope, but three gyros one for a back up to maintain proper operation. The gyroscopes are used to help control movement and maintain the location of the telescope. How Will They Dispose of the Hubble NASA presented two options for disposing of the Hubble telescope. The first option is to remove the Hubble from its orbit and make it fall into the Pacific Ocean in the safest and most controlled manner. The Hubble is located 353 miles or 568 kilometers above the Earth. An uncontrolled drop of this huge telescope from such a high altitude could cause a drastic impact on the surface it does hit. Consequently, that’s never an option to let it fall without some control and certainty of its landing position. The second option is to remove it also from its current orbit but to lift or push it out farther away from Earth. I think this is a better option. It is kind of like storing an old car in a barn, but it may cost more to do it this way. Will, the James Webb, Replace Good Ole Hubble? James Webb Space Telescope (JWST) is the newest and most ambitious space observatory developed and has almost reached completion. This new invention does not aim to replace the Hubble definitely; instead, it is a successor to continue what was initially contributed by the latter. The Hubble uses visible light in getting beautiful images of the numerous stars and galaxies in the universe. In contrast, the Webb is an infrared telescope which seeks to observe those first stars and galaxies created in the universe. These celestial bodies located at a very far distance have their wavelengths mainly in the red region of the spectrum. Consequently, this requires an infrared telescope to have a better observation of its structure and actions. Based on this, we can say that the two space telescopes have different abilities which basically means, it is inappropriate to say that Webb is a direct replacement of the Hubble. Final Thought Why I look forward to James Webb and what it may possibly open up in our understanding, I do not want them to scrap the Hubble though per se.
