What happens when three black holes share the same region of space, all orbiting one another? As Science News reports, it remains a mystery. Their orbits may be so unpredictable that even if their motions were measured to the maximum precision theoretically possible, their orbital paths would still elude us.
Computer simulation of a black hole’s orbit may thus demonstrate some fundamental characteristics of time. And, according to astrophysicist Nathan Leigh, the results show that “Quantum mechanics imprints into the universe chaos at a fundamental level.”
Many things are taking place:
US launches 4 secret spy satellites to orbit | Space
A Northrop Grumman Minotaur IV rocket launched from the Mid-Atlantic Regional Spaceport (MARS) in Virginia today (July 15) at 9:46 a.m. EDT (1346 GMT), carrying the NROL-129 mission to orbit for the U.S. National Reconnaissance Office (NRO) and Space Force.
The NRO develops and operates the nation's fleet of spy satellites , the activities of which are generally classified. So we don't know exactly what the NROL-129 spacecraft will be doing up there, or even what their final orbital destinations are.
Covid-19 In Drones' Orbit
Demand for touchless workplace technology and automation could drive drone investment and M&A.
As the coronavirus outbreak confined workers to their homes and forced companies to make due with skeletal staffs, drone adoption accelerated. For this reason, executives across many industries are seeing the value of drones as a service they could tuck in via acquisitions.

Two astronauts are concentrating on the final set of power upgrade spacewalks on the International Space Station beginning this week.
Quite a lot has been going on:
Exotrail Raises 11M€ for On-orbit transportation for small satellites - SpaceWatch.Global
Exotrail raised 11M€ (13M$) for on-orbit transportation for small satellites. This Series A round was led by two European Venture Capital firms, Karista (through Paris Region Venture Fund) and Innovacom. IXO Private Equity, NCI-Waterstart, Turenne Capital and returning investors 360 Capital, Irdi Soridec Gestion and Bpifrance also invested.
The Series A fundraising enables Exotrail to continue to develop solutions to enhance deployment, improve performance, and reduce space pollution in the rapidly-growing small satellite space market. Exotrail's innovative propulsion systems and mission design and operations software will allow small satellites to optimize their deployment in space, choose their orbit, and prevent collisions, thus reducing space debris.
New AI Calculates Distant Planet Orbits 100,000 Times Faster - ExtremeTech
Our current exoplanet detection technology can’t provide accurate orbital information, but we can get a general idea of the mechanics by analyzing what we do know and modeling the various options. Unfortunately, there are a lot of potential orbits, and modeling a billion or so of them can take many hours even with powerful supercomputers.
According to Tamayo, separating potentially stable from unstable orbits is computationally expensive, even with current supercomputers because there are so many orbits to explore. Tamayo’s SPOCK (Stability of Planetary Orbital Configurations Klassifier) system simplifies the process by combining a pared down model of planetary interactions with machine learning techniques.

Two NASA astronauts finalized their preparations today, ahead of Thursday's spacewalk, to complete battery swaps on the outside of the International Space Station.
NASA Flight Engineer Bob Behnken and Expedition 63 Commander Chris Cassidy organized their tools and readied the Quest airlock for the spacewalk set to begin tomorrow at 7:35 a.m.
