Crisis in Outer Space

Question: Did you ever have a crisis moment in space?

Leroy Chiao: Yes. The biggest thing that went wrong during one of my missions was when we were coming into dock to the International Space Station in our Soyuz spacecraft. We were inside of 1,000 meters and suddenly all of the alarms started going off and we had lights going and alarms, and the next thing you know we actually started rotating away from the space station. We started losing the visual sighting of the space station through the periscope. So, this was a real emergency, and the first thing that hit me was disbelief. You know, usually this is what happens during the training in the simulator. Usually on the actual flight, everything works perfectly.

 

So, the training kicked in and we quickly went through our emergency procedures, I took manual control and I got the spacecraft under control and stopped about 50 meters from the space station. So, the net effect of the failure was that we were actually turning and speeding up towards the space station when we should have been slowing down, so it was quite a dangerous situation. But we got manual control, performed the first manual docking to the station at night.

 

It was one of those situations where afterwards, you know, after we were safe and we were all docked and everything that we kind of took a breath and thought, wow, that was pretty dangerous situation. But it shows you that the training pays off. You know, it was just automatic. We just went right to it and got out – we had our books out already, we went right to the right procedures and executed them and everything went well.

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

Why we're so self-critical of ourselves after meeting someone new

A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

Surprising Science

We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
