![]() Once stabilized, there was much more detail.īut over fifty years' worth of progress in electronics had better improve the quality of the video from the preceeding level. It gets its name from the Southern MAssive Cluster Survey (SMACS), in which the Hubble Space Telescope observed 124 galaxy clusters that are bright at X-ray wavelengths. They weren't so much grainy as blurred when panning. SMACS 0723 is a galaxy cluster located four billion light-years away. The discovery of this object pushes back the formation time of galaxy clusters the largest structures in the Universe held together by gravity by about 700 million years. The videos I saw at the time were in color. The galaxy cluster is called CL J1001+0220 (CL J1001 for short) and is located about 11.1 billion light years from Earth. emission from the galaxy cluster Abell 1213 March 14 2023, by Tomasz Nowakowski SDSS g-band image of the galaxy cluster Abell 1213 with, superimposed, the contour levels of the VLA 1.4 GHz radio. I think the videos are going to be much better than Apollo, not grainy and black and white. Its far larger than Gateway and provides a stable target which won't be affected in case of a rather hard docking. ![]() Most docking in the last twenty years has been between a capsule and the ISS. Is it really a challenge and does it take two astronauts remaining on Orion for docking on astronaut return from the lunar surface? Galaxy Clusters Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) Galaxy Clusters Galaxy clusters are the largest objects in the Universe, spanning distances up to ten million light years, and containing the equivalent mass of a million, billion suns. That’s going to be one of the big challenges. For rendezvous and docking, with something that massive, we haven’t done something like that in lunar space. The big difference is going to be the Starship lander, which is very big. It also lacks easy access for repairs which was an issue on Artemis 1. On Artemis 3, Lunar sample return mass will be constrained by the capacity of Orion, not that of the HLS lander. Regarding mass, Orion may be said to be obese ( already discussed in 2013!). Even then, we may ask if this spacecraft really is better than the Apollo CSM which -unlike Orion- was able to attain a low lunar orbit. He'd better say that quickly while Orion still is the best. We have built the best spacecraft that we’ve ever seen
