Watch how SpaceX’s first human spacecraft performed during its key in-flight escape test – TechCrunch

SpaceX is getting ready to launch its first-ever spacecraft with humans on board, the Commercial Crew Demo-2 mission (DM-2) that will take off from Florida on May 27. There are still a couple of things remaining to finish up prior to flight, including a final parachute system test that’s happening later today. The company also posted a video recap of its most recent uncrewed Crew Dragon flight, the in-flight escape demonstration that it flew on January 19.

The video provides a look at the processes involved in the test, including a look at mission control, with astronauts Bob Behnken and Doug Hurley looking on during the flight. You can see the SpaceX Falcon 9 launch with the Crew Dragon attached, as well as watch it explode in a ball of fire (as intended) during the early emergency separation. Then, watch as the capsule itself descends safety back to the ocean where it’s recovered by a SpaceX vessel.

This is a demonstration of a key system that’s designed as a safety measure, to be used only in the unlikely event of a major malfunction of the rocket during the takeoff phase, but after the spacecraft has left the ground. The system works by quickly and automatically propelling the astronaut-carrying Crew Capsule away from the booster and second stage at a very high speed, to ensure the people aboard are at a safe distance in case of any explosions.

Along with a ground escape system for quickly vacating the capsule and launch area before takeoff, there are a number of safety measures required by NASA for any human spaceflight from U.S. soil with astronauts on board. SpaceX has so far demonstrated that these systems are ready to a degree that has satisfied the agency, and now has only a number of pre-flight checks and run-throughs to get through before the historic May 27 mission.

The cleanest pocket of air on Earth? It's in the Southern Ocean, between Tasmania and Antarctica – National Post

Published

on


The cleanest air on Earth lies in a pocket of sky between Tasmania and Antarctica, scientists say. 

A team of researchers at Colorado State University conducted a bioaerosol study of the Southern Ocean from Tasmania to Antarctica — the first of its kind — and drew air samples at the marine boundary level, where the atmosphere meets the ocean surface. 

“We were able to use the bacteria in the air over the Southern Ocean (SO) as a diagnostic tool to infer key properties of the lower atmosphere,” microbian ecologist Thomas Hill, from Colorado State University, told Science Alert.

Via modelling and analysis, the team noted that the samples were free of aerosol particles — a sure indicator of human activity, like fossil fuel burning, agriculture and fertilizer production — blown in from other parts of the world. The samples were also split into latitudinal zones, so that the team could observe how the air changed as they moved further south.

Via wind patterns, airborne microorganisms can travel vast distances. However, the bacterial make-up of the samples suggested that the closer they were taken to Antarctica, the cleaner they became. This suggests that aerosols from distant land masses and human activities are not travelling south into Antarctic air.

Instead, the samples appear to be composed of microorganisms from the ocean and little else. 

“It suggests that the SO (Southern Ocean) is one of very few places on Earth that has been minimally affected by anthropogenic activities,” Hill said. 

The results counter similar studies that were carried out in oceans in the subtropics and the Northern Hemisphere, which concluded that most microbes came from upwind continents.

Metro Vancouver is in for a treat this week, as we’ll be able to see the Strawberry Moon eclipse shine over the city this Friday.

Named after the red summer fruit, this phenomenon is June’s full moon – or otherwise called the Hot Moon or Rose moon.

This particular moon, however, kicks off 2020’s “eclipse season,” and will be visible during the moonrise and moonset.

You’ll just have to be ready at either 5:30 am or 8 pm, Friday, to see the eclipse over Metro Vancouver. 

So, will you be checking it out this week? 

Friday, June 5th is also the day of the second George Floyd protest, happening downtown.
