This graphic of orbital debris, or “space junk (any human-made object in orbit around the Earth that no longer serves a useful purpose) comes from 2009. The same year, a US communications satellite owned by a private company, Iridium, collided with a non-functioning Russian satellite. The collision destroyed both satellites and created a field of debris that endangered other orbiting satellites. Australian National University researchers working with defence technology company EOS to blast space debris out of orbit.
Space debris (or junk ) is becoming a serious problem as orbits get more congested with decommissioned space craft and other objects, and new satellites. Debris can smash into assets such as the International Space Station, and even a small object can cause great damage in space.

Square Kilometer Array Observatory launched in South Africa will take a decade to complete
The radio telescope is going to be composed of 197 dishes in total. All of them will be 15 metres in diameter.

The South African Radio Astronomy Observatory (SARAO) announced that the Square Kilometre Array Observatory (SKAO) project was successfully launched on Monday. This was finalised after a meeting of SKAO council members held last week approved the establishment of the world’s largest radio telescope. According to
NASA, the Square Kilometre Array will be built in South Africa and Western Australia and the construction and working will take around 10 years. The project aims to measure neutral hydrogen over cosmic time so that the signals from pulsars in the Milky Way can be timed accurately. This will in turn help detect millions of galaxies out to high redshifts.

The Square Kilometre Array Observatory (SKAO) Council was formed after one of the most important radio telescopes in the world, the Arecibo in Puerto Rico, collapsed in December.
FOLLOW US ON:
A new intergovernmental organisation called Square Kilometre Array Observatory (SKAO) Council has been formed with the intention of building the world’s largest radio telescope. On Thursday, the council held its first-ever meeting to approve the plans and start a new journey in space exploration. Though it is headquartered in the UK, SKAO has members from Australia, Canada, China, India, Italy, New Zealand, South Africa, Sweden and the Nether
Square Kilometre Array: Lift-off for world s biggest telescope
One of the grand scientific projects of the 21st Century is Go! .
The first council meeting of the Square Kilometre Array Observatory has actioned plans that will lead to the biggest telescope on Earth being assembled over the coming decade.
Member states approved a thousand pages of documents covering everything from the power to open a bank account to engaging with industrial contractors.
The SKA telescope will comprise a vast formation of radio receivers.
These will be positioned across South Africa and Australia.
The array s resolution and sensitivity, allied to prodigious computing support, will enable astronomers to address some of the most fundamental questions in astrophysics today.
