Kindai University is proposing an alternative to the tags, a reflective sheet that can be attached to the fish. The movement of the tunas will be monitored from space by using a satellite equipped with a laser to irradiate the sheets. SpaceTuna1 will be used to test if the sheets can be observed from 300 km away. [6] [7]
Many trans-Neptunian objects (TNOs) have been discovered; in many cases their positions in this list are approximate, as there is frequently a large uncertainty in their estimated diameters due to their distance from Earth. Solar System objects more massive than 10 21 kilograms are known or expected to be approximately spherical.

This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
The Hubble Space Telescope Comparison between many space telescopes by diameter Overview of active and future telescopes (as of January 2021) This list of space telescopes ( astronomical space observatories ) is grouped by major frequency ranges : gamma ray , x-ray , ultraviolet , visible , infrared , microwave , and radio .
The term artificial objects is closely associated with made by humans or not naturally occurring items that have been sent into space. This is a list of lists of artificial objects in space found on Wikipedia. Category:Lists of artificial objects sent into space; Category:Lists of space missions; Lists of spacecraft.

The possible screw axes are: 2 1, 3 1, 3 2, 4 1, 4 2, 4 3, 6 1, 6 2, 6 3, 6 4, and 6 5. Wherever there is both a rotation or screw axis n and a mirror or glide plane m along the same crystallographic direction, they are represented as a fraction or n/m.
Since 1970, there have been seven lunar rovers, seven Mars rovers, and three asteroid rovers that have successfully landed and explored these extraterrestrial surfaces. In addition, a small helicopter on Mars, Ingenuity , operated from 2021 to 2024.
