While its true that Hubble was designed to get above the atmospheric distortions, modern telescopes shoot a laser dot into the sky and use that to gauge the atmospheric distortion real time. They then use actuators to shift the mirrors shape to make up for the distortions, this gives a clear image. Why space telescopes are still vital is the gasses in our atmosphere block a lot of light wavelengths. Especially infrared. This wavelength is very important for astronomy. This is why we paid $10 billion for the James Webb Telescope. Which will have a totally unrivalled look into the Universe in IR, from searching for planets and their atmospheres, to seeking images from the early Universe where the light has been stretched from being visible into being infrared. Personally I except big break throughs in exoplanets from it. The exoplanet hunters we had up such as Keppler just were not enough to spot Earth sized exoplanets. JWT will be able too. In other news SLS, the giant Moon rocket NASA is building is due for a wet dress rehearsal in a few weeks. But this likely pushes Artemis i, the uncrewed flight round the Moon to early next year. Artemis II will be a crewed flight round the Moon so maybe 2024, and Artemis III the landing on the Moon seems to be about 2025 now. The ESA\NASA lunar space station Lunar Gateway will be built from 2024 to 2027. Parts already under construction. 1 Quote Link to comment Share on other sites More sharing options...

NorthernLights Posted June 9, 2022 Share Posted June 9, 2022 The James Webb was hit by a meteoroid Quote A tiny rock fragment has hit the new James Webb Space Telescope's main mirror. The damage inflicted by the dust-sized micrometeoroid is producing a noticeable effect in the observatory's data but is not expected to limit the mission's overall performance. James Webb was launched in December to succeed the revolutionary - but now ageing - Hubble Space Telescope. Astronomers are due to release its first views of the cosmos on 12 July. The US space agency Nasa said these images would be no less stunning because of what's just happened. https://www.bbc.co.uk/news/science-environment-61744257 0 Quote Link to comment Share on other sites More sharing options...

welshbairn Posted June 28, 2022 Share Posted June 28, 2022 (edited) Rocket Lab are trying to launch a cube sat from NZ to lunar orbit in about 14 minutes. It's part of NASA's return to the Moon project. They sometimes try to catch the booster with a helicopter as it plunges back to Earth, unsuccessfully so far but very dramatic. https://www.nasaspaceflight.com/2022/06/capstone-launch/ Edited June 28, 2022 by welshbairn 1 Quote Link to comment Share on other sites More sharing options...

DA Baracus Posted July 11, 2022 Share Posted July 11, 2022 Didn't get to see it in great detail. I'm sure it's being circulated around now so be easier to check out. It was an image that they said dated back to almost the start of the universe. Looking forward to seeing more images tomorrow. 0 Quote Link to comment Share on other sites More sharing options...

tamthebam Posted July 11, 2022 Share Posted July 11, 2022 Bit of camera shake there. 5/10. Seriously, it's a fantastic photo even if it did remind me of early 1980s Dr Who titles... 0 Quote Link to comment Share on other sites More sharing options...
