But a cleanup of GEO would be nice too.
Wow. So, of the 20 most threatening LEO large derelict objects, 20 are Zenit second stages ? With Envisat immediately behind them. Did Sea Launch desorbited its own stages ? or are those, relics from before their times - different Zenits ?
Apple co-founder Steve Wozniak's new space company is really starting to take shape.Hawaii-based Privateer remains in stealth mode a month after Wozniak and co-founder Alex Fielding announced its existence, but we know the company aims to tackle humanity's growing problem with space junk, which threatens to hinder our exploration of the final frontier. And Privateer will focus, at least initially, on improving our knowledge of the teeming orbital population."We really got started with the goal of building … the Google Maps of space," Fielding told TechCrunch recently.The company has just hired one of the people who will lead this ambitious effort, tapping aerodynamicist and "space environmentalist" Moriba Jah as its chief scientific adviser.
While Privateer was initially thought to be working on orbital debris removal technologies, the company is instead focused on better monitoring of satellites and other objects in orbit. “We want to focus on decision intelligence,” Jah said in an interview during the 72nd International Astronautical Congress. “How do we enable these things and do so in a way that makes space more transparent, makes space more predictable and can develop a body of evidence to help people and hold them accountable for their behaviors.”Jah has developed AstriaGraph, a visualization tool that combines space situational awareness data from a several sources. AstriaGraph will be the core of Privateer’s efforts, he said, creating a “multisourced digital commons of stuff in space.”Privateer will augment that with data from a constellation of satellites it plans to develop. Its first prototype satellite, Pono-1, will launch early next year. The three-unit cubesat will carry a variety of sensors to track and characterize space objects.

On Tuesday, Privateer is officially leaving “stealth mode” and debuting the first version of its software, which will monitor traffic in space. In interviews with CNN Business, the founders laid out a grand vision, with goals to build the type of database that space traffic experts — including governments — currently only dream of.<snip>Eventually, Privateer also hopes to deploy a series of satellites that will use sensors capable of keeping tabs on even the smallest pieces of debris — the currently elusive pieces of garbage under 10 cm. They plan to call the satellites Pono, a Hawaiian word that roughly translates to “do the right thing.”Fielding said the company could have its first assets in space this year by putting its sensors on a satellite already slated for launch. Privateer could launch its own, custom Pono satellites in the years to come as needed, to fill in any blind spots, Fielding said.
A new venture that emerged from stealth this week promises better information about objects in orbit and more tailored space situational awareness services for satellite operators.Privateer, based in Maui, Hawaii, unveiled its first product March 1, a visualization tool called Wayfinder that combines data from several sources, including data from U.S. Space Command and data provided directly by satellite operators.Wayfinder is based on ASTRIAGraph, a similar web application developed by Moriba Jah, a University of Texas at Austin professor who is also chief scientist of Privateer. “It’s a rearchitecting of ASTRIAGraph,” he said in an interview. “ASTRIAGraph is always going to exist, but this is going to be a branch off of that.”
What this means is that Privateer's satellites will have cameras monitoring Earth. 'Talking with investors, seeing where the market's going, the thinking is, if we have satellites up there, why not also have sensors there, that can, you know, provide data,' says Bellucci.With enough satellites looking down - they won't say how many but assure me they will all be designed not to add to the long-term clutter - they will create a camera system from space extensive enough for developers to create apps we can then all use.By offering imagery from space cheaply, Fielding wants to make other companies' satellites obsolete, reducing overlaps. 'I mean why are there 40 satellites over Kyiv right now doing the same thing?' he asks. Researchers without government-sized budgets will be able to look down and see 'people doing bad things'.
It takes everyone working together to make space safe for all. We’re proud to release Crow’s Nest to the space community in support of our shared vision for a sustainable space future. #WeAreAllCrew
Well obviously, they are going to remake Mercury and have it dock to something in space!
