"Imagine how dangerous sailing the high seas would be if all the ships ever lost in history were still drifting on top of the water," says Jan Wörner, European Space Agency (ESA) director general.

It's almost as if we need a tow truck to remove all the thousands of failed satellites from our orbit; incidentally, that's exactly what the ESA is working on.
By 2025, the agency plans on launching the world's first orbiting junk collector, a four-armed robot that tracks down space waste like Pac-Man in a maze.

New reentry CubeSat in orbit
Designed for ESA by Belgium's Von Karman Institute, Qarman will use internal temperature , pressure and brightness sensors to gather precious data on the extreme conditions of reentry as its leading edges are enveloped in scorching plasma.
Qarman's blunt-nosed front contains most of its sensors, protected by a cork-based heatshield. The CubeSat is expected to survive its reentry, although not its subsequent fall to Earth—making it imperative that its results make it back in the time in between, using the Iridium commercial satellite network.
Astronomers discovered a giant planet orbiting a dead white dwarf star - Tech Explorist
Until now, there has never been evidence of a planet that has survived a star's transition to a white dwarf.
Astronomers from the University of Warwick's Department of Physics and the Millennium Nucleus for Planet Formation (NPF) at the University of Valparaíso have recently presented fresh evidence of a giant planet orbiting a white dwarf star. The planet is found in the form of a disc of gas formed from its evaporating atmosphere.
The Neptune-like planet orbits a star a quarter of its size about once every ten days, leaving a comet-like tail of gas comprised of hydrogen, oxygen, and sulfur in its wake.
Bitcoin wallet orbits Earth at 5 Miles Per Second : SpaceChain
The reports about SpaceX Falcon 9 to deliver the hardware wallet technology by SpaceChain came into being on the 6th of December 2019. By the looks of it, this was the first time that a hardware comprising blockchain technology found its way to the International Space Station in almost two years.
The developers of the cryptocurrency wallet, SpaceChain consider the launch of the active Bitcoin node on the International Space Station as a significant milestone. SpaceChain also explains the recent move as the mission to build a completely robust and decentralized blockchain infrastructure that orbits Earth. Moreover, the wallet is way beyond the jurisdiction of any country and none of the blackhat hackers can take control of the Bitcoin wallet.

KinetX Aerospace Navigation Team Critical to Understanding Particles Ejected from the Surface of
In response to the discovery in January 2019 of particles ejecting from the surface of asteroid (101955) Bennu by OSIRIS-REx, the KinetX navigation team reconstructed the ejected particles' trajectories to help characterize these unexpected events.
"Use of the KinetX optical navigation tools and techniques highlights how our corporate capabilities and intellectual property are applied to a diversity of applications," said Coralie Adam , a co-author who leads the KinetX Space Navigation and Flight Dynamics Optical Navigation Team.

University of Cincinnati professor Ou Ma is engineering robotics technology to fix orbiting satellites in his Intelligent Robotics and Autonomous Systems Lab. He envisions robotic satellites that can dock with other satellites for repairs or refueling.
NASA Space Station On-Orbit Status 3 December 2019 - SpaceX Cargo Delivery Upcoming - SpaceRef
The Expedition 61 crew aboard the International Space Station is focusing on a pair of upcoming cargo deliveries after completing a spacewalk on Monday.
SpaceX will launch its 19th Dragon resupply ship aboard a Falcon 9 rocket on Wednesday at 12:51 p.m. EST from Kennedy Space Center in Florida. Dragon is delivering nearly three tons of cargo to the orbiting lab including new science hardware such as the Confined Combustion study, Japan's Hyperspectral Imager Suite (HISUI) and the AzTechSat-1 cubesat developed by Mexican students.
The Space Review: Catalyzing space debris removal, salvage, and use
Unfortunately, salvage and debris cleanup is very difficult under the current international legal space regime and orbital conditions, all of which disincentivize action. First, per Article VIII of the Outer Space Treaty (OST)[1], a State Party on whose registry an object is launched into outer space retains jurisdiction and control of the items launched.
While it may be unclear if anyone is liable for unclaimed debris, it can be argued that the moment a State Party to the OST, via its national entity, touches the debris, the State Party assumes liability for whatever happens according Article VI of the OST, which mandates that State Parties bear “international responsibility” for national activities in outer space and also requires “authorization and continuing supervision” of the involved national actors.
