Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.


He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Changes in engineering and procedures for next manned Dragon flight

SpaceX is making several engineering and operational changes involving flights of its manned Dragon capsule, based on the company’s experience during the first manned flight several months ago.

First, they are reinforcing the heat shield in one area.

After a successful test flight that ended when NASA astronauts Bob Behnken and Doug Hurley splashed down in the Gulf of Mexico on Aug. 2, the company noticed “a little more erosion than we wanted to see” in a few areas of the capsule’s heat shield, Hans Koenigsmann, SpaceX’s vice president of build and flight reliability, said during a press call this week. He said there “was nothing to be concerned with at all times. The astronauts were safe, and the vehicle was working perfectly.”

Second, they are revising the software used to determine the altitude when the capsule’s drogue parachute is released.

Koenigsmann said the company is refining how it measures the capsule’s altitude as it returns to Earth. During the August test flight, the drogue parachutes deployed at a slightly lower altitude than the company expected, but still well within safety parameters, he said.

Finally, they are going to more strictly enforce a 10-mile “keep-out zone” in the ocean where the capsule splashes down. They do not want to see another crowd of recreational boats swarming the landing zone, as happened when the capsule returned to Earth in August.
