Tim Peake can expect to feel like he is “hitting a wall in a fast car” when his space capsule plummets back to Earth in Kazakhstan, the former head of Nasa said today.
Major Peake will re-enter Earth’s atmosphere at more than 500mph, with the Russian Soyuz capsule deploying rocket thrusters to stabilise the landing, the method the Russians have relied on since the Sixties.
Ex-Nasa boss Dan Goldin, appointed by the first President Bush and in charge of 62 US shuttle lift-offs, gave one crucial piece of advice to Major Peake — don’t leave any belongings behind on the International Space Station. The British astronaut will leave the ISS with crewmates Tim Kopra, from America, and Yuri Malenchenko, from Russia, and in less than four hours will be back on Earth.
About three hours after the Soyuz has undocked from the ISS, the middle section containing the crew will break off. The crew will then will pass through the atmosphere at 1,600C — about a third hotter than lava — which will also burn up the two jettisoned sections.
At the start of re-entry, Major Peake is likely to suffer a condition known as entry motion sickness as he plummets back to Earth strapped into the Soyuz.Symptoms include headache, pallor sweating, dizziness, nausea and vomiting.
Mr Goldin said: “For Tim Peake, the excitement will be building. It’s euphoric and such a privilege to be able to do this. My advice to him is enjoy that ride back, savour every minute.
“He’s going to want to make sure he’s got all his gear before he leaves.
“They’ll experience a very high g-force, like shock force. It’s like going fast in a car and hitting a wall.
“The Soyuz lands pretty hard, it doesn’t have a soft landing like the shuttle. It comes down and they fire retro rockets. A team will be sent out to find the capsule and they literally will carry the astronauts back to the crew quarters.
“This mission is absolutely wonderful, England ought to celebrate this wonderful event on Saturday.”
Dan Goldin was in London promoting his KnuEdge start-up that invented voice authentication software capable of verifying a person’s identity in extremely noisy environments.
