Indian missile test endangers International Space Stati…


Jim Bridenstine was addressing employees of the National Aeronautics and Space Administration five days after India shot down a low-orbiting satellite in a missile test to prove it was among the world’s advanced space powers.

Not all of the pieces were big enough to track, Bridenstine explained. “What we are tracking right now, objects big enough to track – we’re talking about 10 centimeters or bigger – about 60 pieces have been tracked.”

The Indian satellite was destroyed at a relatively low altitude of 300km, well below the ISS and most satellites in orbit.

But 24 of the pieces “are going above the apogee of the International Space Station,” said Bridenstine.

“That is a terrible, terrible thing to create an event that sends debris at an apogee that goes above the International Space Station,” he continued, adding: “That kind of activity is not compatible with the future of human spaceflight.”

“It’s unacceptable and NASA needs to be very clear about what its impact to us is.”

The US military tracks objects in space to predict the collision risk for the ISS and for satellites. They are currently tracking 23,000 objects larger than 10 centimeters.

That includes about 10,000 pieces of space debris, of which nearly 3,000 were created by a single event: a Chinese anti-satellite test in 2007 at 852km from the surface.

As a result of the Indian test, the risk of collision with the ISS has increased by 44 percent over 10 days, Bridenstine said.

But the risk will dissipate over time as much of the debris will burn up as it enters the atmosphere. DM

No, not really. But now that we have your attention, we wanted to tell you a little bit about what happened at SARS.

Tom Moyane and his cronies bequeathed South Africa with a R48-billion tax shortfall, as of February 2018. It’s the only thing that grew under Moyane’s tenure… the year before, the hole had been R30.7-billion. And to fund those shortfalls, you know who has to cough up? You – the South African taxpayer.

It was the sterling work of a team of investigative journalists, Scorpio’s Pauli van Wyk and Marianne Thamm along with our great friends at amaBhungane, that caused the SARS capturers to be finally flushed out of the system. Moyane, Makwakwa… the lot of them… gone.

But our job is not yet done. We need more readers to become Maverick Insiders, the friends who will help ensure that many more investigations will come. Contributions go directly towards growing our editorial team and ensuring that Daily Maverick and Scorpio have a sustainable future. We can’t rely on advertising and don’t want to restrict access to only those who can afford a paywall subscription. Membership is about more than just contributing financially – it is about how we Defend Truth, together.

So, if you feel so inclined, and would like a way to support the cause, please join our community of Maverick Insiders…. you could view it as the opposite of a sin tax. And if you are already Maverick Insider, tell your mother, call a friend, whisper to your loved one, shout at your boss, write to a stranger, announce it on your social network. The battle for the future of South Africa is on, and you can be part of it.
