Hubble Looks at a Face-On Grand Spiral

https://www.nasa.gov/image-feature/godd … and-spiral

There might be a Chinese version of a Hubble lunched in the next year but so far NASA's Hubble is the only telescope designed to be maintained in space by astronauts and possibly a robot as discussed here. Five Space Shuttle missions have repaired, upgraded, and replaced systems on the Hubble telescope, including all five of the main instruments. Over 15,000 papers based on Hubble data have been published in peer-reviewed journals. http://archive.stsci.edu/hst/bibliography/pubstat.html JWST is said to be a Hubble replacement but that is not an accurate description as JWST operates in IR. Habitable Exoplanet Imaging Mission would be a more true replacement,  It would be an optical, UV and infrared telescope, however it would not launch until 2035 or maybe as late as 2040. https://www.nationalacademies.org/news/ … -community

Re: Hubble Space Telescope Permanent Maintenance Station

The article I saw was that Nasa was looking to see if Space x could bring Hubble to a higher orbit since over time its decaying back towards earth.
If we are going to do that why not show starship without refueling can actually do something besides being a taxi to LEO.

Re: Hubble Space Telescope Permanent Maintenance Station

It's getting close to being in need of more maintenance as well as upgrades as well but currently we do not have a safe haven platform to even think of going to do this repair.

Re: Hubble Space Telescope Permanent Maintenance Station

Hubble Captures Movie of DART Asteroid Impact Debris

https://spaceref.com/science-and-explor … ct-debris/

Like a sports photographer at an auto-racing event, NASA’s Hubble Space Telescope captured a series of photos of asteroid Dimorphos when it was deliberately hit by a 1,200-pound NASA spacecraft called DART on September 26, 2022.

The primary objective of DART, which stands for Double Asteroid Redirection Test, was to test our ability to alter the asteroid’s trajectory as it orbits its larger companion asteroid, Didymos. Though neither Didymos nor Dimorphos poses any threat to Earth, data from the mission will help inform researchers how to potentially divert an asteroid’s path away from Earth, if ever necessary. The DART experiment also provided fresh insights into planetary collisions that may have been common in the early solar system.

Hubble’s time-lapse movie of the aftermath of DART’s collision reveals surprising and remarkable, hour-by-hour changes as dust and chunks of debris were flung into space. Smashing head on into the asteroid at 13,000 miles per hour, the DART impactor blasted over 1,000 tons of dust and rock off of the asteroid.

Re: Hubble Space Telescope Permanent Maintenance Station

Hubble Observes Cosmic Contortions


Another news item

'Cosmic contortions'
https://www.spacedaily.com/reports/Cosm … s_999.html

A massive galaxy cluster in the constellation Cetus dominates the centre of this image from the NASA/ESA Hubble Space Telescope. This image is populated with a serene collection of elliptical and spiral galaxies, but galaxies surrounding the central cluster - which is named SPT-CL J0019-2026 - appear stretched into bright arcs, as if distorted by a gargantuan magnifying glass.

This cosmic contortion is called gravitational lensing, and it occurs when a massive object like a galaxy cluster has a sufficiently powerful gravitational field to distort and magnify the light from background objects. Gravitational lenses magnify light from objects that would usually be too distant and faint to observe, and so these lenses can extend Hubble's view even deeper into the Universe.

This observation is part of an ongoing project to fill short gaps in Hubble's observing schedule by systematically exploring the most massive galaxy clusters in the distant Universe, in the hopes of identifying promising targets for further study with both Hubble and the NASA/ESA/CSA James Webb Space Telescope. This particular galaxy cluster lies at a vast distance of 4.6 billion light years from Earth.

Re: Hubble Space Telescope Permanent Maintenance Station

AS valuable as the Hubble has been and now what the JWST has shown we have not developed the means to maintain them since the shuttle was no more. Nasa has chosen to build then a knew at bigger and better billion-dollar costs instead making them disposable.

Re: Hubble Space Telescope Permanent Maintenance Station

For Mars_B4_Moon re #68 and #69 .... thank you for these links to recent Hubble observations!

Here is a report on possible solutions to the "Sinking Hubble" problem ...

Gizmodo
There's a New Plan to Relocate Hubble Space Telescope and Extend Its Lifespan

George Dvorsky
Tue, May 9, 2023 at 2:35 PM EDT

The Hubble Space Telescope.

Like any satellite in Earth orbit, the Hubble Space Telescope is sinking, and it’s been doing so for the past 33 years. A proposed solution from two space startups offers an intriguing strategy for safely boosting Hubble’s orbit, allowing NASA to extend the lifespan of its storied observatory.

Hubble is currently healthy, but atmospheric drag will eventually cause it to re-enter our planet’s atmosphere at some point during the mid-to-late 2030s. Since launching in 1990, the telescope’s orbital height has fallen by roughly 18 miles (30 kilometers).


Not ready to say goodbye, NASA issued a Request for Information (RFI) late last year, asking the commercial sector to devise strategies for reboosting Hubble’s orbit. The winning team would then have to provide the necessary resources and services to get the job done, including the launch vehicle, spacecraft, crew (if applicable), and mission operations (excluding Hubble operations).

SpaceX expressed interest shortly after the RFI was posted, saying it’s working on a feasibility study. The Elon Musk-led company is looking to leverage its Polaris Program, a series of missions organized and led by billionaire astronaut Jared Isaacman. Exact details of the SpaceX plan are not known, but the involvement of the Polaris Program and Isaacman suggest it would be a crewed mission aboard the company’s Crew Dragon spacecraft.

We now know of a second response to NASA’s request (assuming SpaceX goes through with its proposal): a joint proposal pitched by California-based Momentus Space and Tokyo-based Astroscale. Working together, the two companies would relocate Hubble to a higher Earth orbit and then remove any threatening debris within the telescope’s new orbit.

The collaboration makes sense, as Momentus’s Vigoride platform is designed to transport payloads across various orbits. Just yesterday, Momentus announced that Vigoride-5’s experimental water-propulsion system lifted the ‘space tug’ some 1.86 miles (3 kilometers) above its original orbit. In response to a Gizmodo query, a Momentus spokesperson confirmed that the company’s Microwave Electrothermal Thruster (MET), which uses distilled water as propellant, would be used in the mission to boost Hubble’s orbit, should this bid be chosen.

“Even at 33, Hubble is fully capable of continuing its mission; where it is aging is in its orbital stability,” John Rood, Momentus chief executive officer, said in a company statement. “I am thrilled that we collaborated to offer NASA a very cost-effective way to continue to operate this billion-dollar scientific investment by leveraging new robotic in-space servicing technology.”

As for Astroscale, a startup seeking to provide orbital trash removal services, its contribution would be in providing rendezvous, proximity operations, and docking services—a suite of capabilities otherwise known as RPOD.

The proposed mission to lift Hubble’s orbital trajectory would be completely robotic, precluding the need for humans to be launched to space. The proposed plan would see a yet-to-be-named small rocket launching a Vigoride space tug to low Earth orbit. The spacecraft, equipped with Astroscale’s RPOD tech, would approach and capture the space-based telescope. Locked together, Vigoride would perform a series of maneuvers in the attempt to raise Hubble by as much as 31 miles (50 km)—a higher orbit than the one originally occupied by the telescope. This task complete, the system would then undock from Hubble and begin the process of removing potentially threatening debris in Hubble’s orbital vicinity.

Much of this is experimental and untested, and that could make NASA a bit nervous when considering this proposal. That said, Ron Lopez, president and managing director of Astroscale U.S., said the plan gives NASA options, “options that were not available during the five previous crewed servicing missions and that leverage the best of in-space servicing to achieve mission objectives and advance U.S. leadership in space.”

Hubble during a Space Shuttle servicing mission.

Those five previous crewed servicing missions referred to by Lopez are the Space Shuttle missions performed between 1993 and 2009, during which the crews replaced batteries, gyroscopes, and electronics boxes, and installed updated science instrumentation. Hubble was designed for in-space servicing, which could prove useful during the attempt to raise its orbit. We’ll have to wait for NASA to choose a plan and a team, but it’s a relief to know that the space agency is looking out for one of its most prized possessions.
