NASA PR — Imagine a machine that can build a part or a tool as the need arises, whether on Earth, Mars or the International Space Station.

Almost 10 years ago, engineers at NASA’s Langley Research Center imagined just that. They developed the Electron Beam Freeform Fabrication, or EBF3, a process that uses an electron beam gun, a dual wire feed and computer controls to manufacture metallic structures for building parts or tools in hours, rather than days or weeks.

First Taurus II Flight Could Slip at Least One Month After Engine Fire


Test Stand Fire Threatens Taurus 2 Launch Schedule
Space News

The fuel line that failed was part of the engine, not the test stand, the source said….The source, who asked not to be identified because he was not authorized to speak publicly on the matter, said the AJ-26  team investigating the mishap suspects a flaw in the metal used for that particular fuel line.

“If this looks like it’s a processing flaw when the metal was made, then the problem is probably just a one-off,” the source said.

Three AJ-26 engines have completed acceptance testing at Stennis and been delivered to Orbital’s Taurus 2 integration facility at NASA’s Wallops Flight Facility in Virginia. Two of those engines were intended to be used for an upcoming hold-down test of the Taurus 2’s first stage and then refurbished for the rocket’s second flight. The other engine already at Wallops was to have been paired with the now-damaged engine for the Taurus 2’s maiden launch, targeted for October.

That launch — a demonstration flight meant to help qualify the vehicle to launch cargo capsules bound for the international space station — now appears likely to slip at least a month since the next available engine still must undergo acceptance testing at Stennis, according to the source.

Commercial Zero Gravity Flights Coming to Europe


The 'Zero-G" Airbus A300

Zero-gravity experience lifts off at Le Bourget

Once available only to astronauts and scientists, the weightless experience is about to become a bit more accessible, provided you’ve got the cash.

Novespace managing director and ex-astronaut Jean-Francois Clervoy announced Tuesday that he plans to offer commercial flights, including one before the end of this year.

Final approval from France’s civil aviation authority is pending, and the price tag — provisionally set at 4,000 euros (5,700 dollars) — has yet to be finalized.

But Clervoy envisions half-a-dozen sorties a year with 40 passengers each starting in 2012. It would be only the third such commercial service in the world, along with one in the United States and one in Russia.

TEA Party Space Platform Released


TPIS PR — Washington, DC, June 23, 2011 — TEA Party in Space (TPIS), a non-partisan organization, today publicly released the TEA Party Space Platform (link to platform).

“This is our response to the vacuum of leadership in Washington, D.C., for America’s national space enterprise,” said Andrew Gasser, President of TPIS. “Whether it’s timidity from the White House or Congress’ earmark-laden ‘compromises’, our space dreams will be stuck on this planet unless someone articulates a vision based on economic and technical reality, so that’s what we’ve done.”

NASA, Sierra Nevada Honor Workers for HL-20 Work


NASA PR – The story began on June 3, 1982, when a camera in an Australian P-3 patrol plane captured images of a Soviet ship recovering a space craft from the Indian Ocean.

It continued Wednesday, when Sierra Nevada Corp. honored the employees — many now retired — at NASA’s Langley Research Center who used those photos to carve a cherry wood model of the Soviet craft, a BOR-4, then used that model as the jumping-off point to the HL-20 (for horizontal lander) personnel space vehicle.

A proper ending, says Sierra Nevada chairman, Mark Sirangelo, would be for its version of the HL-20, the “Dream Chaser,” to ferry crews from Earth to the International Space Station and back.

ESA, NASA Discuss Joint Manned Missions
Aviation Week

The European Space Agency (ESA) and NASA are discussing plans to build a joint U.S.-European spacecraft based on existing designs that could ferry astronauts to the International Space Station and one day carry humans beyond low Earth orbit.

Speaking at the Paris air show June 20, ESA Director General Jean-Jacques Dordain said the space agencies are hashing out a plan that would combine the service module of ESA’s Automated Transfer Vehicle (ATV) — a spacecraft built by EADS Astrium that is used to haul cargo to the orbiting complex — with NASA’s Multipurpose Crew Vehicle, a space capsule based on the Orion Crew Exploration Vehicle that Lockheed Martin Space Systems has been developing for NASA over the past six years.

“We are working with NASA to see how we can combine the current capabilities of ATV with what NASA is doing on crew transportation systems to see how we can make a joint vehicle,” Dordain says. The two sides are shooting for a rough outline of the joint concept and its development costs by fall, allowing ample time for ESA member states to evaluate the proposal ahead of their budget-setting ministerial council at the end of 2012.

Space News’ Brian Berger has posted a couple of Tweets on the recent testing mishap for Orbital Sciences Corporation’s Taurus II AJ-26 engine:


> Orbital is acknowledging one of the Taurus 2’s AJ26 engines was badly damaged June 9 when leaking RP caught fire.

> Has #orbital said how the fire will impact Taurus 2 demo by EOY ’11? It’s possible. Depends on whether test stand or engine is to blame.

The first Taurus II test flight is schedule for early October. If all goes well, OSC will fly the first Cygnus freighter on a flight in December. If that test goes well, OSC will begin delivering cargo to the International Space Station in 2012.

Stay tuned for updates. Same bat blog. Probably a different bat time….

Bat Update: Via Aviation Week:

“There was significant damage to the engine,” Orbital spokesman Baron Beneski said June 21.

Beneski and Glenn Mahone, a spokesman for Aerojet, say the AJ26 engine shut down prematurely after a fuel leak developed during a hot-fire acceptance test, and the leaking kerosene fuel ignited. While the engine was damaged, the test stand at Stennis Space Center suffered only minor damage, the spokesmen said in separate telephone interviews.

Mahone says a team of rocket engine experts from Aerojet, Orbital and NASA is investigating the cause of the mishap and the extent of the damage to the engine.

“How much we’re not sure,” Mahone says. “There is an investigation going on. The engine did not burn up.”

The results of the investigation and prognosis for the engine and the Taurus II should come together by the end of this week or early next week, Beneski says. Two other AJ26 engines have completed hot-fire acceptance testing without mishap, according to the Aerojet website.


LRO Reveals Moon in New Ways


New maps of lunar surface characteristics LOLA data give us three complementary views of the near side of the moon: the contours of the landscape, or topography (left), along with new maps of the surface slope values (middle) and the roughness of the topography (right). All three views are centered on the relatively young impact crater Tycho, with the Orientale basin on the left side. The slope magnitude indicates the steepness of terrain, while roughness indicates the presence of large blocks, both of which are important for surface operations.

NASA has declared full mission success for the Lunar Reconnaissance Orbiter (LRO). LRO changed our view of the entire moon and brought it into sharper focus with unprecedented detail.

NASA’s Exploration Systems Mission Directorate (ESMD) operated the LRO spacecraft and its instruments during the one-year mission phase. Now that the final data from the instruments have been added to the agency’s Planetary Data System, the mission has completed the full success requirements. The data system, which is publicly available, archives data from past and present planetary missions as well as astronomical observations and laboratory data.
