Hi All,

On 2021-12-25 15:24:15, I wrote to August Abolins:

It's now, a day after launch, almost 240 km from earth. That's not even half
way the distance to the moon. And about 16,5% of the distance to it's
destination point in space. It will take about 29 days to get there. It will
take so long to get there, because there is no propulsion anymore (except for
some short burns for course corrections). It's in the balistic fase on it's
path to it's destination, and because of the gravitational pull of the earth
it's constantly slowing down slightly. It speed now is about 1.7 km/s relative
to earth, while during the launch fase it topped at about 10 km/s...

If you're interested you can follow it's journey for yourself on this website:

Bye, Wilfred.
