Its day 2 of the MASTER workshop on #spacedebris, with presentations on environmental impact assessments and #collisionavoidance.

Tomorrow's programme includes:

- the sustainability of the debris environment
- managing debris with & for society

Sign up! https://t.co/0UrJAH9oUS

Its day 1 of ESA's MASTER workshop, all about better understanding the #spacedebris environment through modelling.

Up for discussion soon, "The impact of satellites and space debris on Hubble Space Telescope observations." Find out more and sign up here👉https://t.co/sIH3LBhXmu

@Till_83 @moribajah @AussieSpaceGirl Till, we have all the 900,000 objects >1 cm covered here, coming from the MASTER model. And yes, it's really a lot!

European Conference on #SpaceDebris – Call for Papers!📰🛰️🚮

The largest dedicated gathering on space debris, bringing together internationally renowned experts over 4 days, invites you to submit your abstract👉https://t.co/eV0vfUFeZE

🗓️Deadline: 15 Nov 2020

It's #TimeToAct.

[European Space Agency @esa]

During 30 years, the NASA/ESA @HUBBLE_space Telescope has witnessed the changing nature of spaceflight and bears the scars of a fruiftul life in space - many tiny impact craters. What can we learn from these and what does the future hold for Hubble? 👉 https://t.co/9nrBkKnad3

@ProfHughLewis Looking forward to discuss this at the upcoming IOC! Being in favour of a zero footprint solution, I see many associated questions, i.a.: would everyone be required to perform a controlled reentry? Is there a time dimension to the footprint still beyond end-of-mission? etc.

This Kepler petition to the FCC about @SpaceX #Starlink is making for quite interesting reading. #SpaceLaw #SpacePolicy #SpaceSustainability

Interested in taking part in a rubbish challenge?🛰️🗑️

To manoeuvre or not to manoeuvre... that's the question posed by ESA's #SpaceDebris Office and Advanced Concepts Team.

Some additional bits of useful information about #Aeolus/#Starlink from SpaceX:

- Starlink 44 is operational and capable of avoidance maneuvers if necessary

- In three months the Starlink fleet has performed 16 collision avoidance maneuvers without any manual input (!)

For the first time ever, ESA has performed a 'collision avoidance manoeuvre' to protect one of its satellites from colliding with a 'mega constellation'

Update from SpaceX on their Starlink constellation: “57 Starlink satellites are communicating with SpaceX’s Earth stations... 45 Starlink satellites have reached their operational altitude ..."

So, with various numbers floating around: how does the proposed 12000 satellite @SpaceX #Starlink satellite constellation seize up to the current number of artificial objects in orbit around earth? A thread, with diagrams:
