This is going to get exciting.

Even though I personally like the Dream Chaser spacecraft better, I believe SpaceX has a leg up with their manned Dragon vehicle because they are already using its cousin to make successful deliveries to the Space Station and the US is anxious to get away from Russian dependency.

Will be neat to watch it all come about.

the Russians have been lagging on a number of module launches and have a half hearted interest in ISS. Like the Chinese they want there own station.

True, but they need to get that M Proton Rocket to work first instead of lighting it up like a 4th of July in order to build their own station.

McALLEN (AP) — Building and operating a private rocket launch site along the coast in the southernmost tip of Texas is unlikely to jeopardize the existence of protected animal species and create few unavoidable impacts, according to a final federal environmental review.
The Federal Aviation Administration released the environmental impact statement for California-based SpaceX on Thursday. It does not guarantee that the FAA would issue launch licenses there, but it is an essential step in that direction.
SpaceX has proposed launching 12 rockets per year from the site east of Brownsville and 3 miles north of the U.S.-Mexico border called Boca Chica Beach, but did not make any promises Thursday. If built, it would be the first commercial orbital launch site.
"Though Brownsville remains a finalist for the development of a commercial orbital launch complex, the decision will not be made until all technical and regulatory due diligence is complete," SpaceX spokeswoman Hannah Post said in an email.
She noted several more steps have to be cleared, and that, "While the timing of some of these critical steps is not within SpaceX's control, we are hopeful that these will be complete in the near future."
The U.S. Fish and Wildlife Service, which had raised concerns about possible impact on habitat for some endangered species, ultimately concluded that "the project is not likely to jeopardize the continued existence of any listed or proposed to be listed species nor adversely modify piping plover critical habitat."
But wildlife officials don't expect the project to be harmless: Two individual cats, either from the endangered ocelot or jaguarondi species, could be lost as a result of the project in spite of efforts to avoid just that with measures such as posting warning signs along the road leading to the launch site. And federal wildlife officials also anticipate that more than 7 miles of beachfront used by nesting sea turtles could be disturbed by security patrols, though driving is already permitted on the beach.
SpaceX has agreed to a list of measures aimed at minimizing the environmental impact including educating workers about threatened and endangered animals. It also plans to adopt a 3-mile section of the beach and participate in beach cleanups and educational programs.
The Texas launches would create unavoidable noise for residents of a nearby neighborhood and dramatically alter the landscape of sand dunes, wetlands and grasses, but other environmental impacts can be mitigated, the report said.
SpaceX already launches from Cape Canaveral in Florida and Vandenberg Air Force Base in California. In addition to serving commercial satellite customers, SpaceX also resupplies the International Space Station.
SpaceX founder and chief executive Elon Musk indicated last month that the company planned to develop the launch site in Texas. Sites in Florida, Georgia and Puerto Rico had been considered as well, but the Texas site was always much further along in the planning process.
The document released Thursday describes why SpaceX eliminated sites in Florida (too much beachfront development) and Puerto Rico (difficulty of transporting cargo from mainland) from contention, but does not mention Georgia.

SpaceX Unveils ‘Step Change’ Dragon ‘V2’
SpaceX has unveiled the human-rated version of its Dragon spacecraft
May 30, 2014 Guy Norris | AWIN First


SpaceX
Space Exploration Technologies (SpaceX) has unveiled the human-rated version of its Dragon spacecraft with which it is competing for NASA’s Commercial Crew Program to ferry astronauts to the International Space Station (ISS).

The ‘V2’ version, revealed by SpaceX CEP Elon Musk at the company’s Hawthorne, Calif, facility on May 29, is designed to carry a crew of seven and differs considerably from the cargo variant currently flown to the ISS. “We wanted to take a big step in technology – a step change in space travel,” says Musk. “It really takes things to the next level,” he adds.

Configured with eight side-mounted SuperDraco thruster engines clustered in pairs, and supported on extendable landing legs protruding through the heat shield, the vehicle is designed to be able to land under its own power “anywhere on Earth with the accuracy of a helicopter. That’s something I think a modern spaceship should be able to do,” says Musk.

The vehicle will also be able to dock directly to the ISS autonomously without needing the large Canadarm 2 robotic arm that is used to maneuver the cargo Dragon into place. Dragon V2 also retains the ‘Version 1” parachute system as a safety back up in case of an engine anomaly, says Musk. “So when it reaches a certain altitude just before landing it will test the engines, and verify they are all working and proceed to a propulsive landing. But if any anomaly is detected it will then deploy the parachutes even in the event of the propulsion system not working.”

The vehicle can lose up to two engines and still make a safe landing says Musk who considers the development of the 16,000 lb thrust SuperDraco thruster as the most significant technical challenge involved in the development of the Dragon V2. “That’s an engine that has to produce a tremendous amount of thrust and yet be very light. It’s also got to throttle over a wide range, and it’s got to react very quickly. It was quite a tricky thing to develop.”

SpaceX completed qualification testing of the thruster earlier this week at its McGregor, Texas, test site. The engine system is also designed to power the Dragon’s launch escape system as well as provide a propulsive landing capability. The regeneratively-cooled engine is not only capable of deep-throttling but is designed for multiple restarts, and is produced from Inconel using an additive manufacturing, direct metal laser sintering process. “This will be the first fully printed rocket engine to see flight,” he adds. Each one is contained in a protected nacelle “in case anything goes wrong.”

“The reason this is important is it enables rapid reusability of the spacecraft. You can just reload propellant and fly again,” says Musk who envisages up to 10 flights per vehicle before significant refurbishment. Other highlights noted by Musk included the composite overwrapped titanium spheres containing the pressurized helium for the propulsion tanks for the SuperDraco engine. The engines operate at a chamber pressure of around 1,000 psi and are fed from propellant tanks located around the base of the vehicle.

The new Dragon also features the third generation of the SpaceX-specific phenolic impregnated carbon ablator (PICA-X) heat shield technology. “It ablates less as it enters the atmosphere” Musk adds. Inside the vehicle are flat panel display and control screens, with mechanical switches and knobs for key functions.

The first key milestone for the Dragon Version 2 is a launch pad abort test in which the vehicle will be positioned at pad height and then launched to simulate an emergency. “Next year we expect to do the high altitude abort test at Max Q (max dynamic pressure) and execute an abort. These are tests, so they could go wrong,” adds Musk. “Conceivably we could do the first flight to orbit at the end of 2015, and the first flight with people in 2016,” he says. Musk adds that SpaceX will attempt to continue development of the enhanced Dragon even if it loses the contest for the NASA contract. “We will do our best to continue development,” he adds.

A buddy of mine who works at NASA share with photo of the ORION capsule getting it's heat shield put together.

At the Operations and Checkout Building at the Kennedy Space Center the Orion crew module and heat shield are being moved into position for the mating operation. The heat shield will be tested on Orion's first flight in December as it protects the crew module from reentry temperatures reaching 4000 degrees Fahrenheit.

Wow...just wow!

It's own powered landing capability...and it includes the parachute for a backup.

That's pretty cool if you ask me.

I'm still a big Dream Chaser fan...but this makes the SpaceX offering very palatable.

Yup Dragon V2 or Dream chaser are the best bets in my opinion for commercial crew. Heck if NASA really wanted a leg up in space I say use them both.

In the Milky Way there’s a single X-ray binary — a system consisting of a black hole capturing and heating material from an orbiting companion star — known as Cygnus X-1. But 30 million light-years away in the Whirlpool galaxy, M51, there are hundreds of X-ray points of light and a full 10 X-ray binaries.

Nearly a million seconds of observing time with NASA’s Chandra X-ray Observatory has revealed these specks. “This is the deepest, high-resolution exposure of the full disk of any spiral galaxy that’s ever been taken in the X-ray,” said Roy Kilgard, from Wesleyan University, at a talk presented at the American Astronomical Society meeting today in Boston. “It’s a remarkably rich data set.”

Within the image there are 450 X-ray points of light, 10 of which are likely X-ray binaries.

The Whilpool galaxy is thought to have so many X-ray binaries because it’s in the process of colliding with a smaller companion galaxy. This interaction triggers waves of star formation, creating new stars at a rate seven times faster than the Milky Way and supernova deaths at a rate 10-100 times faster. The more-massive stars simply race through their evolution in a few million years and collapse to form neutron stars or black holes quickly.

“In this image, there’s a very strong correlation between the fuzzy purple stuff, which is hot gas in the X-ray, and the fuzzy red stuff, which is hydrogen gas in the optical,” said Kilgard. “Both of these are tracing the star formation very actively. You can see it really enhanced in the northern arm that approaches the companion galaxy.”

Eight of the 10 X-ray binaries are located close to star forming regions.

Chandra is providing astronomers with an in depth look at a class of objects that has only one example in the Milky Way.

“We’re catching them at a short window in their evolutionary cycle,” said Kilgard. “The massive star that formed the black hole has died, and the massive star that is accreting material onto the black hole has not yet died. The window at which these objects are X-ray bright is really short. It’s maybe only tens of thousands of years.”
