ADSL on its last legs in South Africa

  By   Daniel Puchert Partially state-owned telecommunications company Telkom announced in its financial results for the year ending 31 March 2025 that its ADSL subscribers had more than halved to under 30,000. According to the company’s operational data, ADSL lines decreased from 64,959 in March 2024 to 29,770. This 54.2% decline highlights that the legacy broadband technology is slowly approaching the end of the road. Telkom’s ADSL business peaked at the end of March 2016 with 1.01 million subscribers — two years after fibre upstart Vumatel  broke ground in Parkhurst . What followed was a sharp decline in Telkom ADSL subscribers. Customers connected to its copper networks decreased by more than 500,000 over the next four years. This was partly driven by Telkom itself, which began actively switching off its copper network in some neighbourhoods. If it did not have fibre in the area, it would offer a “fixed line lookalike” wireless service that ran over its cellular ...

Perseverance’s First Full-Color Look at Mars

Perseverance’s First Full-Color Look at Mars

This is the first high-resolution, color image to be sent back by the Hazard Cameras (Hazcams)

This is the first high-resolution, color image to be sent back by the Hazard Cameras (Hazcams) on the underside of NASA’s Perseverance Mars rover after its landing on Feb. 18, 2021.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent missions by NASA in cooperation with ESA (the European Space Agency), would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance and Curiosity rovers.

Andrew Watson: The 'most influential' black footballer for decades lost to history

  By Andrew Aloia BBC Sport Last updated on 11 October 2021 11 October 2021 . From the section Football Watson was a trailblazer who helped transform how football was played There are two murals of black footballers facing one another across an alleyway in Glasgow. One helped shape football as we know it, the other is Pele. Andrew Watson captained Scotland to a 6-1 win over England on his debut in 1881. He was a pioneer, the world's first black international, but for more than a century the significance of his achievements went unrecognised. Research conducted over the past three decades has left us with some biographical details: a man descended of slaves and of those who enslaved them, born in Guyana, raised to become an English gentleman and famed as one of Scottish football's first icons. And yet today, 100 years on from his death aged 64, Watson remains something of an enigma, the picture built around him a fractured one. His grainy, faded, sepia image evokes many differen...
