It;s kinda sad. Those Birds never have and never will fly.
the one that came closest was crushed.
They should be in a Museum, Perhaps the Russians would be willing to sell them as mounted displays down the line.

has reported that it is not known at present when the in-flight abort test will be carried out. However, it will likely take place later than this fall when the test had been scheduled to take place.

Before the in-flight abort test takes place, SpaceX will launch an orbital test flight of the crew-rated dragon (without the crew). Once that mission has been completed and that Dragon has been recovered and restored, it will be used on the in-flight abort test.

Whereas the launch pad abort test on May 6, 2015, demonstrated the crew-rated Dragon’s ability to lift astronauts away from an accident at the launch site, the in-flight abort test will validate the craft’s ability to do the same – from a launch vehicle on ascent.

If everything goes according to plan, the Falcon 9 will lift off from LC-39A and, at about a minute-and-a-half into the flight, when the booster is passing through the period of the flight known as maximum dynamic pressure or “max-Q” – the abort system will be activated. The Dragon spacecraft will then pull away from the Falcon 9, deploy its parachutes and splash down in the Atlantic Ocean.

has successfully completed several significant Thermal Protection System (TPS) material development tests for its

. The TPS is responsible for protecting crew members and cargo from the high temperatures the spacecraft will experience during re-entry.

The TPS tests were completed at NASA’s Ames Research Center and Johnson Space Center under reimbursable Space Act Agreements (SAA). The tests provided critical data needed to support the upcoming TPS subsystem Critical Design Review (CDR) and to validate Dream Chaser TPS manufacturing readiness. Additional TPS certification testing is also planned at the centers beginning in the fall of 2015. SNC made the announcement Friday, June 26 during NASA’s launch activities to media and social media at the agency’s Kennedy Space Center in Florida where the Dream Chaser tiles are manufactured.

“Safety of crew and cargo is most important to our team as we continue to mature the spacecraft design,” said

, corporate vice president, SNC’s Space Systems. “For several years, we have worked collaboratively with Johnson and Ames, leveraging their existing infrastructure, materials and expertise to mature and customize the TPS for our unique spacecraft. Our TPS is lighter, stronger and more efficient than previous generations. We have met or exceeded all mission requirements. We are now prepared to enter the Critical Design Review phase for this system.”

Over 100 arc jet cycles and radiant heat tests were completed at Johnson’s Radiant Heat Test Facility (RHTF) and Ames’ Aerodynamic Heating Facility (AHF). RHTF provided results supporting thermal characterization of the developmental TPS materials. The test data were then used for thermal modeling, analysis and TPS sizing. The Ames AHF arc jet tests were performed as a second phase in the development testing to gauge the material performance in environments simulating Dream Chaser flight conditions.

Valuable arc jet test results support SNC’s certification of the manufacturing capability of a high-temperature material called TUFROC. TUFROC will be used on the high-temperature nose and wing leading edges of the Dream Chaser spacecraft. The TUFROC test articles were manufactured in Kennedy’s historic Thermal Protection System Facility to SNC’s specifications as part of the TUFROC technology transfer from Ames to SNC.

In addition to the TUFROC testing, arc jet cycles and radiant heat tests in high-heating, simulated re-entry environments were conducted to measure the thermal performance of new silica tile coating developed by NASA and SNC. SNC’s assessments show that these new coatings offer the same thermal protection as previously flown tile coatings, but at a greatly reduced cost.

The Dream Chaser spacecraft is the only reusable, lifting-body, low-g, and horizontal runway-landing spacecraft in the world capable of crewed and uncrewed transportation. The crewed variant has been under development in partnership with

On the track with Einstein gravitational waves

oPdqsJh.jpg

(Defensa.com) With LISA Technology (LTP) Package, Airbus Defence and Space has delivered the core of scientific LISA Pathfinder spacecraft that will test the technology with which to observe from space described by Einstein's gravitational waves. Beyond this check, the ability to measure the gravitational radiation will allow astronomers to study our universe in a completely different way. Future systems of telescopes can observe exotic objects such as colliding black holes or neutron stars as never before possible.

The LTP has been installed on the satellite has also built Airbus Defence and Space. Both LTP as the satellite itself must now prove its operational suitability in a complete series of tests at the company IABG in Ottobrunn, near Munich (Germany). LISA Pathfinder is laying the foundation of a great space observatory that will ultimately be observed directly and accurately measure gravitational waves. These tiny distortions in space-time technology require highly sensitive and highly accurate measurement and operation can only be tested in a space environment without interference.

The LTP weighs approximately 150 kilos and basically comprises a laser interferometer which will measure changes in the distance between two test cubes gold / platinum high accuracy, having a weight of 1.96 kilos each. Once in orbit, the two proof masses are released by a release mechanism delicate and kept in position by a weak electrostatic field can be controlled very precisely. The interferometric laser and electrostatic sensors monitor the movement of proof masses inside the satellite, making sure that the test masses remain outside any disturbance. The interferometer can measure the relative position and orientation of the test masses which are spaced about 40 centimeters each other- with a high degree of very high precision (<0.01 nanometers, less than one-millionth the thickness of a human hair ).

The launch of LISA Pathfinder is scheduled for autumn 2015. Once in orbit, a propulsion module dedicated LISA Pathfinder will carry about 1.5 million kilometers from Earth, away from any interference from our planet. Airbus Defence and Space in UK was chosen by the European Space Agency (ESA) to build the LISA Pathfinder and is also responsible for the supply of integrated turnkey satellite. ESA and the German Aerospace Center have ordered Airbus Defence and Space in Germany address for LTP systems, developed with contributions from various European research institutes.

Speaking publicly for the first time since a Falcon 9 rocket failure that destroyed a Dragon cargo capsule for the International Space Station, SpaceX founder Elon Musk said Tuesday that engineers are still piecing together what happened during the June 28 accident in hopes of announcing more details within a few days.

The rocket failure occurred minutes after liftoff from Cape Canaveral — the first such mishap in the Falcon 9’s 19 missions to date — causing the booster to disintegrate 45 kilometers (28 miles) over the Atlantic Ocean.

“Obviously, this is a huge blow to SpaceX, and we take these missions incredibly seriously,” Musk said in a question and answer session Tuesday at an International Space Station conference in Boston. “Everyone that can engage in the investigation at SpaceX is very, very focused on that. In this case, the data does seem to be quite difficult to interpret. Whatever happened is clearly not a simple, straightforward thing, so we want to spend as much time as possible just reviewing the data.”

Echoing earlier statements by SpaceX, Musk said the company has enlisted help from NASA, the Federal Aviation Administration and other customers in the investigation.

He said engineers will “look at both what we think most likely happened, and then anything that’s a close call, and then try to address all of those things and maximize the probability of success on future missions.”

Musk hopes to release more details on the failure by the end of this week after further data analysis and engineering reviews.

“At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data,” Musk said. “So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”

Musk did not address how long the Falcon 9 rocket might be grounded in the aftermath of the accident while engineers find the cause and implement corrective actions. SpaceX officials have said they informed customers booked to fly on upcoming Falcon 9 launches to expect delays of a few months.

“As soon as we’ve got a clear line on what happened … we’ll certainly put out that story,” Musk said. “My only reticence about saying something quite yet is I don’t want to say something that subsequently turns out to be a misunderstanding of the situation.”

SpaceX officials said recovery teams in the Atlantic Ocean northeast of Cape Canaveral have retrieved debris from the launch failure, but the wreckage is small and likely holds few clues to the cause of the anomaly. Instead, engineers are focused on analyzing more than 3,000 channels of telemetry, including on-board video sources, to re-construct the flight timeline.

“The biggest thing that’s needed in the short term is the ability to just gather all the data, and create a very precise timeline, so that, by the millisecond, we know what each sensor was reading, and we can correlate that with ground video,” Musk said. “One of the biggest challenges is matching things to the exact time.

“When you’re dealing in milliseconds, all that stuff actually makes quite a bit of difference, so that’s the biggest effort we’ve been engaged in so far — just creating a super-detailed timeline,” Musk said.

Michael Suffredini, NASA’s space station program manager, said the research outpost is doing fine without the more than 4,000 pounds of cargo lost aboard SpaceX’s Falcon 9 rocket.

The supplies lost included a new docking ring designed to receive future commercial crew capsules in development by Boeing and SpaceX. A second docking adapter is already built awaiting launch, and spare parts exist to assemble a third unit, officials said.

A spacesuit, components needed to repair the lab’s water filtration system, food and crew provisions, and experiments also went down in the Dragon spacecraft.

The Falcon 9 failure was the second in back-to-back failures on missions to resupply the space station. A Russian Progress cargo freighter spun out of control in late April.

NASA contracted with SpaceX and Orbital ATK to deliver logistics to the space station after the retirement of the space shuttle. Orbital had its own launch failure in October 2014, in which an Antares supply rocket heading for the space station crashed just after blastoff from Virginia.

“We’re still doing research on ISS, the crew is healthy, the vehicle is healthy, and unfortunately we have lost, in the last eight months, three vehicles,” Suffredini said, adding the failures have had a “big impact” on the space station program.

The string of failures since October 2014 came after just one lost mission to the space station in the previous 16 years, a period in which more than 150 launches went up to build and outfit the complex.

“As a program, we always assumed we’d lose one or two logistics vehicles and that we’d have to deal with that,” Suffredini said. “Never in my wildest dreams did I imagine we’d lose three in eight months, but you deal with the cards that are dealt, so that’s where we are today.”

Russia’s Progress resupply freighter returned to flight with a successful launch July 3. It docked with the space station two days later with nearly three tons of fuel, oxygen, food and experiments.

Three new crew members are due to depart for the space station July 22 aboard a Russian Soyuz ferry capsule, raising the lab’s crew back to six residents.

Then attention turns to a Japanese resupply launch scheduled for Aug. 16. Japan’s HTV cargo freighter is the biggest supply transporter in the space station’s fleet, and Suffredini said managers have adjusted some of the spaceship’s load to make up for items lost on earlier missions.

He assured researchers that officials made only minor changes to the complement of experiments manifested on the HTV flight, removing some hardware to be used for research next year. That cargo can be flown to the space station on a later mission, Suffredini said.

“All the research on HTV remains,” Suffredini said. “We did have to modify some of the other supplies to make sure we have everything we needed.”

Before the end of the year — even if no SpaceX missions launch — three more cargo deliveries are on tap. The space station is scheduled to receive two more Progress supply vehicles in September and November, and Orbital ATK’s Cygnus logistics carrier is set for launch in early December aboard a United Launch Alliance Atlas 5 rocket.

Orbital ATK contracted with ULA to launch the resupply flight while engineers redesign the company’s Antares booster for new engines in the wake of last year’s launch failure. Officials expect the Antares rocket to resume launching in March 2016.

Under NASA’s deals with SpaceX and Orbital ATK, the space agency can withhold a final payment to the contractor if a cargo flight fails, but the companies are not required to refly a mission.

will make the closest approach ever to Pluto, and the United States will become the first nation to visit this dwarf planet in the outer reaches of our solar system. This July 4 marked the tenth anniversary of Deep Impact, mankind’s first mission to reach out and touch a comet. It was on July 20, 1969 that Neil Armstrong and Buzz Aldrin made their giant leap for humankind. It was on July 30, 1971 that the lunar rover was driven on the surface of the Moon for the very first time. It was on July 4, 1997 that Pathfinder arrived on Mars. Furthermore, it was on July 14, 1965 – 50 years ago next week – that Mariner 4 flew by and sent us the very close-up first pictures of Mars.

Today, a half century after we received those first pictures of the Red Planet, we’re able to make a significant announcement that will further our nation’s

These distinguished, veteran astronauts are blazing a new trail, a trail that will one day land them in the history books and Americans on the surface of Mars.
For as long as I’ve been Administrator, President Obama has made it very clear that returning the launches of American astronauts to American soil is a top priority – and he has persistently supported this initiative in his budget requests to Congress. Had we received everything he asked for, we’d be preparing to send these astronauts to space on commercial carriers as soon as this year. As it stands, we’re currently working toward launching in 2017, and today’s announcement allows our astronauts to begin training for these flights starting now.

We are on a

Our

initiative makes these parallel endeavors possible. By working with American companies to get our astronauts to the ISS, NASA is able to focus on game-changing technologies, the Orion spacecraft and the Space Launch System (SLS) rocket that are geared toward getting astronauts to deep space.

Furthermore, there are real economic benefits to bolstering America’s emerging commercial space market. We have over 350 American companies working across 36 states on our commercial crew initiative. Every dollar we invest in commercial crew is a dollar we invest in ourselves, rather than in the Russian economy.

Our plans to return launches to American soil also make fiscal sense. It currently costs $76 million per astronaut to fly on a Russian spacecraft. On an American-owned spacecraft, the average cost will be $58 million per astronaut. What’s more, each mission will carry four crewmembers instead of three, along with 100 kg of materials to support the important science and research we conduct on the ISS.

For these reasons, our

program is a worthy successor to the incredible 30-year run of the Space Shuttle Program. The decision that President Bush made in 2004 to retire the Space Shuttle was not an easy decision, but it was the right decision. As you’ll recall, it was the recommendation of the Columbia Accident Investigation Board, and endorsed by many people in the space community – including yours truly.

I cannot think of a better way to continue our celebration of independence this July than to mark this milestone as we look to reassert our space travel independence and end our sole reliance on Russia to get American astronauts to the International Space Station.

I also want to take this opportunity to offer a special word of congratulations to astronaut candidates from the

, who are transitioning into flight-ready status. These eight outstanding Americans – four of them women, four of them men — were selected from a pool of more than 6,300 applicants – our second largest pool of applicants, ever.

The enthusiasm for NASA’s astronaut program reminds us that journeying to space continues to be the dream of Americans everywhere. So my message to members of our incredible NASA Family, is that you must never lose sight of the fact that by your work every day, you inspire today’s students to become tomorrow’s leaders, scientists, engineers and astronauts.

NASA on Thursday named four astronauts who will train for test flights of new Boeing and SpaceX capsules, likely becoming the first crews to launch from the Space Coast since the final shuttle mission four years ago.

Bob Behnken, Eric Boe, Doug Hurley and Sunita Williams are veteran test pilots who have flown on the shuttle and the International Space Station.

The orbital test flights to the station, which could launch in 2017, hope to pave the way for regular trips by the new commercial crew vehicles, ending reliance on Russia for access to and from the outpost.

"I remember when I launched from Kennedy the first time on a U.S. space shuttle, and it was pretty amazing," Williams said in a NASA video released Thursday. "So I can only imagine what it's going to be like after this long period of time to get back on a spacecraft at Kennedy."

SpaceX plans to launch its Falcon 9 rocket — which suffered a failure on its last flight that is now under investigation — and Dragon capsules from Kennedy Space Center's pad 39A. Boeing will launch CST-100 capsules on United Launch Alliance's Atlas V rocket from Cape Canaveral Air Force Station.

While Williams' reference to KSC suggested she would fly with SpaceX, NASA said the four astronauts will train with both companies and have not yet been assigned to flights.

Two-person crews will fly the first test flights by each capsule, after they have completed an orbital test flight without people on board.

Company proposals anticipate an all-NASA crew flying SpaceX's Dragon test flight, with Boeing's CST-100 carrying a split NASA-Boeing crew. Boeing has not yet identified its astronaut.

That means three of the four NASA astronauts likely will fly the two test missions, with one serving as a backup.

"These distinguished, veteran astronauts are blazing a new trail," said NASA Administrator Charles Bolden.

Behnken and Boe are Air Force colonels who each flew two shuttle missions. Behnken until recently was chief of NASA's Astronaut Office at Johnson Space Center, and Boe has served as its deputy chief.

"I'm honored to get the opportunity to participate with this new group, and to work with a team to get us on to this new era in spaceflight," Boe said in the NASA video.

A retired Marine Corps colonel, Hurley's two shuttle missions included the last one, which blasted off four years ago this week.

He said a "huge" team at NASA, together with Boeing and SpaceX teams, would work to make the commercial crew vehicles " as safe as possible."

Behnken said by working shoulder-to-shoulder with the companies, the astronauts were "instrumental in making sure the vehicles are ready for the first flights when the time comes."

Williams is a Navy captain and helicopter pilot whose 322 days in space during two ISS expeditions rank her sixth all-time among U.S. astronauts and second among all women. She earned a master's degree in engineering management from the Melbourne-based Florida Institute of Technology in 1995.

NASA last fall awarded Boeing a contract worth up to $4.2 billion, and SpaceX one worth up to $2.6 billion. Each company is guaranteed at least two flights to the ISS after NASA certifies their vehicles as safe.

Bolden said flights on average would cost $58 million per astronaut, compared to $76 million on Russia's Soyuz spacecraft.

NASA hopes to begin commercial crew flights in 2017. However, the space agency says that timeline will be delayed if Congress does not provide the $1.2 billion it requested for the program next year. Current budget plans are at least $225 million below that total.

The station is expected to operate at least through 2024.

It's showtime for Pluto; prepare to be amazed by NASA flyby

i6v6jbZ.jpg

CAPE CANAVERAL, Fla. (AP) — Pluto, reveal thyself, and Earthlings, enjoy the show.

On Tuesday, NASA's New Horizons spacecraft will sweep past Pluto and present the previously unexplored world in all its icy glory.

It promises to be the biggest planetary unveiling in a quarter-century. The curtain hasn't been pulled back like this since NASA's Voyager 2 shed light on Neptune in 1989.

Now it's little Pluto's turn to shine way out on the frigid fringes of our solar system.

New Horizons has traveled 3 billion miles over 9½ years to get to this historic point. The fastest spacecraft ever launched, it carries the most powerful suite of science instruments ever sent on a scouting and reconnaissance mission of a new, unfamiliar world.

Guarantees principal scientist Alan Stern, "We're going to knock your socks off."

The size of a baby grand piano, the spacecraft will come closest to Pluto on Tuesday morning — at 7:49 a.m. EDT. That's when New Horizons is predicted to pass within 7,767 miles of Pluto. Fourteen minutes later, the spacecraft will zoom within 17,931 miles of Charon, Pluto's jumbo moon.

For the plutophiles among us, it will be cause to celebrate, especially for those gathered at the operations center at Johns Hopkins University's Applied Physics Laboratory in Laurel, Maryland. The lab designed and built the spacecraft for NASA, and has been managing its roundabout route through the solar system.

"What NASA's doing with New Horizons is unprecedented in our time and probably something close to the last train to Clarksville, the last picture show, for a very, very long time," says Stern, a planetary scientist with the Southwest Research Institute in Boulder, Colorado.

It is the last stop in NASA's quest to explore every planet in our solar system, starting with Venus in 1962. And in a cosmic coincidence, the Pluto visit falls on the 50th anniversary of the first-ever flyby of Mars, by Mariner 4.

Yes, we all know Pluto is no longer an official planet, merely a dwarf, but it still enjoyed full planet status when New Horizons rocketed from Cape Canaveral, Florida, on Jan. 19, 2006. Pluto's demotion came just seven months later, a sore subject still for many.

"We're kind of running the anchor leg with Pluto to finish the relay," Stern says.

The sneak peeks of Pluto in recent weeks are getting "juicier and juicier," says Johns Hopkins project scientist Hal Weaver. "The science team is just drooling over these pictures."

This July 8, 2015 image provided by NASA/Johns Hopkins University Applied Physics Laboratory/Southwe …

The Hubble Space Telescope previously captured the best pictures of Pluto. If the pixelated blobs of pictures had been of Earth, though, not even the continents would have been visible.

The New Horizons team is turning "a point of light into a planet," Stern says.

An image released last week shows a copper-colored Pluto bearing, a large, bright spot in the shape of a heart.

Scientists expect image resolution to improve dramatically by Tuesday. The 7,767-mile span at closest approach is about the distance between Seattle and Sydney.

New Horizons, weighing less than 1,000 pounds including fuel, has seven instruments that will be going full force during the encounter. It's expected to collect 5,000 times as much data, for instance, as Mariner 4.

"We're going to rewrite the book," Weaver says. "This is it — this is our once-in-a-lifetime opportunity to see it."

The team gets one crack at this.

"We're trying to hit a very small box, relatively speaking," says Mark Holdridge, the encounter mission manager. "It's 60 by 90 miles, and we're going 30,000 mph, and we're trying to hit that box within a plus or minus 100 seconds."

The only planet in our solar system discovered by an American, Pluto actually is a mini solar system unto itself. Pluto — just two-thirds the size of our own moon — has big moon Charon that's just over half its size, as well as baby moons Styx, Nix, Hydra and Kerberos. The names are associated with the underworld in which the mythological god, Pluto, reigned. New Horizons will observe each known moon and keep a lookout for more.

Scientists involved in the $700 million effort want to get a good look at Pluto and Charon, and get a handle on their surfaces and chemical composition. They also plan to measure the temperature and pressure in Pluto's nitrogen-rich atmosphere and determine how much gas is escaping into space. Temperatures can plunge to nearly minus-400 degrees.

Bill McKinnon, a New Horizons team member from Washington University in St. Louis, Missouri, expects to see craters and possible volcanic remnants. A liquid ocean and a rocky core may lie beneath the icy shell.

"Anybody who thinks that when we go to Pluto, we're going to find cold, dead ice balls is in for a rude shock," McKinnon says. "I'm really hoping to see a very active and dynamic world."

Pluto has tantalized astronomers since its 1930 discovery by Clyde Tombaugh using the Lowell Observatory in Flagstaff, Arizona. Some of Tombaugh's ashes are aboard New Horizons. His two children, now in their 70s, plan to be at Johns Hopkins for the encounter.

With its tilted, elongated 248-year orbit, Pluto has made it only a third of the way around the sun since its discovery. The amount of sunlight that reaches Pluto is so dim that at high noon it looks like twilight here on Earth. The massive surrounding Kuiper Belt, in fact, is called the Twilight Zone. The New Horizons team has its eyes on a few much smaller objects in the Kuiper Belt, and is hoping for a mission extension as the spacecraft continues toward the solar system exit on the heels of NASA's Voyagers 1 and 2 and Pioneers 10 and 11.

For now, signals take 4½ hours to travel one-way between New Horizons and flight controllers in Maryland.

New Horizons' science instruments will be cranked up to collect maximum data Tuesday, leaving no time to send back data. In fact, scientists won't be absolutely certain of success until Tuesday night, 13 hours following New Horizons' closest approach, when it "phones home."

It will be Wednesday before the closest of Pluto's close-ups are available for release. And it will be well into next year — October 2016 — before all the anticipated data are transmitted to Earth.

"We're all going to have to be patient," urges deputy project scientist Cathy Olkin.

For everyone involved, this is a mission of delayed gratification.
