Final answer:
The Hubble Space Telescope (HST) is the space object that is still sending back images of space 30 years later. It was once criticized as "NASA's $1.5 billion blunder" but was fixed by astronauts. Since then, the HST has captured stunning images of the universe.
Step-by-step explanation:
The space object that is still sending back images of space 30 years later is the Hubble Space Telescope (HST). It was once criticized as "NASA's $1.5 billion blunder" due to a flaw in its optics that caused blurry images. However, astronauts were able to fix this by installing corrective optics during a space mission in 1993. Since then, the HST has been able to capture stunning and detailed images of distant galaxies, stars, and other celestial objects.
