Private Space Missions Multiplying Like Rabbits
by Douglas Messier
Managing Editor (Parabolic Arc)
With the spate of announcements about private space missions over the past year, it’s easy to lose track of the who, what, where, when, why and how of the flights.
As a public service, Parabolic Arc has collected information about all five of the announced missions.

Sunset, Starship rise…?
Space, a little at a time
MiTEE is a cool space experiment out of the University of Michigan. Faculty led, undergraduate, graduate and PhD student team, developed and got launched a cube (stack) satellite that is demonstrating the use of tethers for de orbiting spacecraft, a serious need in this day of thousand plus satellite constellations.
As a note of interest this was on the first successful Virgin Orbit launch.
What Dreams we Dream
WOW! A cool SETI theory…
Not much more to be said so I post the intro to the article from Centauri Dreams, about an article/Theory by James Benford. Cool…
Was the Wow! Signal Due to Power Beaming Leakage?
by PAUL GILSTER on JANUARY 22, 2021
The Wow! signal has a storied history in the SETI community, a one-off detection at the Ohio State ‘Big Ear’ observatory in 1977 that Jim Benford, among others, considers the most interesting candidate signal ever received. A plasma physicist and CEO of Microwave Sciences, Benford returns to Centauri Dreams today with a closer look at the signal and its striking characteristics, which admit to a variety of explanations, though only one that the author believes fits all the parameters. A second reception of the Wow! might tell us a great deal, but is such an event likely? So far all repeat observations have failed and, as Benford points out, there may be reason to assume they must. The essay below is a shorter version of the paper Jim has submitted to Astrobiology.
Our space science Economy has assets
NASA’s OSIRIS-REx probe could make a 2nd stop at infamous asteroid Apophis, at Space.com, and noted in several space related blogs, eMags. This sounds like a fantastic use of a remarkable space asset.
The Japanese asteroid prospector Hayabusa2 dropped off its samples from Ryugu at Earth and is on its way for more exploration last year: Farewell, Ryugu! Japan’s Hayabusa2 Probe Leaves Asteroid for Journey Home
These craft and others such as craft like the voyagers continue to return immensely valuable data long after their primary mission is complete. One of the things NASA and other space science organizations struggle with is supporting these ships long after the original funding timeline is past. This is a great problem to have and by and large the money is found since these are very cheap deep space projects in the big picture.
So my title, the economy of ‘outer space’ is all about data, science, prospecting right now. These are valuable assets that we need to support to provide returns orders of magnitude greater than the cost in the sense of other ways of getting that data, data that is both live affirming in its fascination and valuable as part of the bedrock of our understanding of the universe.

Cool Stars, Kinda Literally
There are a class of celestial objects much heavier than our systems Jupiter but about the same size. They are not really planets just balls of dense hot gas, but they are not really stars because they lack the mass to collapse and heat their core to ignite sustained fusion. These Brown Dwarves are probably one of the most common objects in our universe but little is known about them because until recently they were essentially impossible to find. With new tools and new techniques this fascinating class of in between are coming into focus.
Another fascinating article from Centauri Dreams.
