Braunschweig, Germany (SPX) Jun 24, 2023
Astronomic observations indicate the existence of so-called "dark matter" which makes up more than 80% of all matter and, as far as we know, interacts with ordinary visible matter only via gravity. In particular, no proof for the interaction with photons (the elementary particles of which also light is composed), has yet been established - hence the term "dark" for this type of matter. It remain

Today we started planning at a location short of our intended drive end position. Mars has, once again, not read our script! Regular readers of this blog will have noticed lately that many reports start with some news about a shortened drive that didn't quite complete, and that Abigail got really excited on June 20th, when three drives in a row had completed successfully. And that's not the rove
