Tahanson it was you, a while back but not too long ago you had seen an article from 'Vice Media'
the post is in the Mars Radio thread

This is an interesting idea (if my interpretation is correct) and this is the first time I've heard/read it.
The mission, which is nicknamed Hongmeng after the primordial mist of Chinese mythology, offers a riff on this idea that sidesteps the headaches of landing and constructing an observatory on the Moon’s surface.
Chen Xuelei, a professor at the National Astronomical Observatory at the Chinese Academy of Sciences who serves as the project scientist for DSL, said the mission could provide “a first peek of the cosmic dawn and dark age” as well as “potential for great discoveries” across a host of other fields such as Sun science, planets and exoplanets, and radio signals from other galaxies.

People might have missed news on 'Arecibo' with all stuff like Wars and Pandemic going on, there was also constant news in election cycles of vote counting and re-counting and appeals for vote recounts during the Biden vs Trump 2020 United States presidential election, a unrest or a Riot against 'alleged rigged' votes by Trump supporters, a police lockdown and Joe Biden sworn in at the U.S. Capitol on January 20, year 2021. the Arecibo telescope probably got less news coverage this time when it collapsed on December 2020. A number of articles now say it will become an education center.

Falcon 9 leading candidate to launch European science mission
https://spacenews.com/falcon-9-leading- … e-mission/
WASHINGTON — A European astrophysics spacecraft stranded when Russia cut off access to Soyuz launch vehicles may instead fly on a SpaceX Falcon 9, NASA officials said Oct. 17.
At a meeting of NASA’s Astrophysics Advisory Council, Mark Clampin, director of the agency’s astrophysics division, said his understanding is that the European Space Agency was leaning towards launching its Euclid mission on a Falcon 9 in mid to late 2023.
NASA is a partner on Euclid, a space telescope that will operate around the Earth-sun L-2 Lagrange point 1.5 million kilometers from Earth to study dark energy, dark matter and other aspects of cosmology. The 2,160-kilogram spacecraft was to launch on a Soyuz rocket from French Guiana in 2023.
Those plans changed, though, after Russia invaded in Ukraine in February, leading to a series of sanctions from Western countries and responses from Russia. That included Russia halting Soyuz launches from French Guiana, leaving several ESA and other European missions looking for new rides to space.
“The current situation with Euclid really comes down to the current political situation,” Clampin said, citing the loss of access to Soyuz. “Right now, ESA is investigating SpaceX Falcon 9 options for late 2023.” That launch could take place in mid-2023, officials later said at the meeting.

ESA moves two missions to Falcon 9
https://spacenews.com/esa-moves-two-mis … -falcon-9/
The European Space Agency now plans to launch a space telescope and an asteroid mission on Falcon 9 rockets because of its loss of access to Soyuz vehicles and delays in the introduction of the Ariane 6.
At an Oct. 20 press briefing after a meeting of the ESA Council, ESA Director General Josef Aschbacher said the agency had decided to launch the Euclid astrophysics mission on a Falcon 9 in 2023 and Hera, an asteroid mission, in 2024.
Euclid, a cosmology mission featuring a space telescope operating at the Earth-sun L-2 Lagrange point, was originally scheduled to launch on Soyuz, but needed a new launch vehicle after Russia halted Soyuz launch operations from French Guiana in response to Western sanctions. Falcon 9 had emerged as the likely option to launch Euclid, something confirmed by NASA officials Oct. 17 who said that ESA was conducting a feasibility study on using Falcon 9 to launch Euclid.
Euclid was one of two ESA missions that had been scheduled to launch on Soyuz. The other, an Earth science mission called EarthCARE, will launch on Europe’s Vega C, Ashcbacher said.
Hera is a mission that will fly to the near-Earth asteroid Didymos and its moon Dimorphos, the target of NASA’s Double Asteroid Redirection Test (DART) mission that collided with Dimorphos last month. Hera will study the asteroids, including the effects on Dimorphos from the DART collision.
Hera was scheduled to launch by the end of 2024 on an Ariane 6, a schedule Aschbacher said was no longer feasible given the latest delay in the first Ariane 6 launch that ESA announced Oct. 19. “Given the rampup that is expected on Ariane 6, it will not be possible to launch on Ariane 6,” he said. “Therefore, this will be launched on the Falcon 9.”
ESA did not disclose the cost of shifting the missions to Falcon 9, including any Soyuz launch contract deposits it may have forfeited with the change. Günther Hasinger, ESA director of science, said the change would have a “positive effect” on the science budget because it would save time versus waiting for a European launch. “I think this is a positive move for the science budget.”

ESA, China conduct spacecraft-rocket integration tests but joint science mission delayed to 2025
https://spacenews.com/esa-china-conduct … d-to-2025/
Last year Airbus sent a structural thermal model of the payload module to Shanghai for integration with the IAMCAS platform and qualification of the satellite.
SMILE is a Sino-European joint mission expected to be launched in April 2025, according to CAS’s National Space Science Center (NSSC). SMILE was last year slated for launch in November 2024, following a number of delays to the project.
The three-year mission will study the interaction between the solar wind and the Earth’s magnetosphere and knock-on effects in the ionosphere, as well as phenomena such as coronal mass ejections. It will operate in a highly inclined, highly elliptical orbit around Earth which will take it a third of the way to the Moon at apogee.
The mission was selected in 2015 from 13 joint Sino-European proposals. SMILE originally targeted launch on a Vega-C rocket from Europe’s Spaceport in Kourou in 2021, but has faced a number of delays.
Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a planned joint venture mission between the European Space Agency and the Chinese Academy of Sciences. SMILE will image for the first time the magnetosphere of the Sun in soft X-rays and UV during up to 40 hours per orbit, improving our understanding of the dynamic interaction between the solar wind and Earth's magnetosphere.

Humanity has Never Seen the sky in the Longest Wavelengths. That Could Change With a new Space Telescope
https://www.universetoday.com/160334/hu … telescope/
Technological revolutions can bring about dramatic changes in various fields, some of which are only tangentially related to the field being disrupted. Occasionally, a few technological revolutions happen simultaneously, enabling concepts that would have been impossible without any of them. Such revolutions are currently happening in the space industry. With rockets more massive than ever coming online, and mega-constellations of satellites roaming our skies, there is plenty of disruption going on. Now a team from MIT hopes to use those technologies to look at an area of astronomy that has never been seen before – low-frequency radio astronomy.

Seems like a longer wavelength would require even larger mirrors and a much taller distance to the initial lense...

How NASA's Roman Space Telescope Will Rewind the Universe

So it would seem China is looking at UV spectroscopy? It might be to examine UV activity on transit-detected close-in exoplanets orbiting their stars, perhaps try examine structure and composition of exoplanet atmospheres and surfaces, while looking at 'photochemistry'. Not sure if it would need service, robots or a crewed mission.

TianLin: a UV-optical large aperture space telescope for habitable worlds
https://spie.org/Publications/Proceedin … 12.2656976
It is expected that the ongoing and future space-borne planet survey missions including TESS, PLATO will detect thousands of small to medium-sized planets via the transit technique, including over a hundred habitable terrestrial rocky planets. To conduct detailed study of these terrestrial planets, particularly those cool ones with wide orbits, the exoplanet community has proposed various followup missions. The currently proposed ESA mission ARIEL is a first step for this purpose, and it is capable of the characterizations of planets down to warm super-Earths. The NASA HabEx and LUVOIR missions are mega projects to further tackle down to habitable rocky planets, which are now merged and to be launched in 2040-2045 if approved. In the meanwhile, China is funding a concept study of a 6-m class UV to optical space telescope named Tianling (a Chinese word meaning neighbours in the sky) that aims to start its operation around 2035 and last for 5+ years. Tianling will be mainly dedicated for the characterization rocky planets in the habitable zones (HZ) around nearby stars. We describe briefly the concept study of this mission and propose a baseline requirement of the telescope and instrumental parameters based on our preliminary simulation results.
Hubble has already looked at ultraviolet through infrared. NASA also has 2 very similar concept missions planned LUVOIR-A and LUVOIR-B are 'JWST' style compacted Space Telescopes that will unfold but they are much bigger and examine UV, known as the 'Large Ultraviolet Optical Infrared Surveyor'
Maybe China is planning on getting there first?

LISA was a joint proposed NASA-ESA space probe to detect and accurately measure gravitational waves and then use them to make observations.
Gravitational waves are waves of the intensity of gravity generated by the accelerated masses of an orbital binary system that propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as waves similar to electromagnetic waves but the gravitational equivalent.
LISA Pathfinder, formerly Small Missions for Advanced Research in Technology-2 (SMART-2), was an ESA spacecraft that was launched on the 3rd of December 2015 on board Vega flight VV06. The mission tested technologies needed for the Laser Interferometer Space Antenna (LISA)

ESA Ariel mentioned in this thread, Atmospheric Remote-sensing Infrared Exoplanet Large-survey working with ESA Cheops launched 2019 & Plato scheduled for 2026 and NASA's already operating JWST
https://www.cosmos.esa.int/web/ariel
The objective of Ariel is to perform a chemical sensus of a large (of order 1000) well selected diverse sample of primarily warm and hot exoplanets orbiting relatively nearby host stars with a range of spectral types from A to M. The key science questions Ariel will address are:
What are the physical processes shaping planetary atmospheres?
What are exoplanets made of?
How do planets and planetary systems form and evolve?
The target selection will be made before launch based on ESA science team and community inputs, and can be updated throughout the mission. The mission will deliver a homogeneous catalogue of planetary spectra, yielding refined molecular abundances, chemical gradients and atmospheric structure; diurnal and seasonal variations; presence of clouds and measurement of albedo.

China previously had unveiled plans for the largest optical telescopes but it never happened is it smog or light pollution problems, they have done Radio which cuts through all t he dust and clouds. Optical will be blocked by dirt and cloud but sometimes a project is put on hold in the Western world also.

NASA Reveals Multi-Billion JWST Successor That Will Search For Life on Earth-Like Exoplanets By 2040s
https://www.sciencetimes.com/articles/4 … -earth.htm
The observatory will be built from the ground up to be upgradeable by robots, Futurism reported. That means that future spacecraft will be able to visit it and upgrade or repair its main components.
https://futurism.com/the-byte/nasa-unve … en-planets
However, it would be a long trip if that is the case. Just like the JWST, the HWO space telescope will circle the Sun at a Lagrange Point that will keep it close to Earth, around a million miles distant.
But the observatory will not be the next multibillion-dollar telescope launched by NASA in the coming years. If all goes as planned, the government will deploy its dark energy and exoplanet-hunting Nancy Grace Roman Observatory around 2027.
So far, numerous concepts have been made for NASA's HWO. One of them is the single-segment, 4-meter mirror observatory called HabEx and a multisegmented, 15-meter observatory called LUVOIR. The HWO will likely fall somewhere in the middle of both concepts, with a combination of technology influenced by both.
Making it maintainable and upgradeable, like NASA's Hubble Space Telescope is, might provide scientists some breathing room and flexibility in its evolution. It may also make HWO more appealing to Congress, which is critical given NASA's financial limits and challenges in getting financing for the JWST.
