Orion Flight Test Hardware Thrives Under Pressure

Published on Dec 2, 2013

Hardware that will keep harmful gases away from the Orion’s spacecraft during its first trip to space proved it won’t bend under pressure during a recent test at NASA’s Marshall Space Flight Center. The diaphragm for Exploration Flight Test (EFT)-1 was joined to an adapter prototype for pressurized testing. For the test, the adapter was sealed and a vacuum pump was connected to the diaphragm. The vacuum pressure simulates atmospheric conditions the hardware may experience during the mission. (NASA/MSFC)

Two-Minute Tour: An Ultra-Compact Dwarf Galaxy

Published on Sep 25, 2013

Astronomers may have discovered the densest galaxy in the nearby Universe. The galaxy, known as M60-UCD1, is located about 54 million light years from Earth. M60-UCD1 is packed with an extraordinary number of stars and this has led scientists to classify it as an “ultra-compact dwarf galaxy.” This means that this galaxy is smaller and has more stars than just a regular dwarf galaxy. While astronomers already knew this, it wasn’t until these latest results from Chandra, Hubble and telescopes on the ground that they knew just how dense this galaxy truly is. M60-UCD1 has the mass about 200 million times our sun and, remarkably, about half of this mass is packed into a radius of just about 80 light years. That translates into the density of stars in this part of M60-UCD1 being about 15,000 times greater than what’s found in Earth’s neighborhood in the Milky Way. Astronomers have been trying to determine where these ultra-compact dwarf galaxies fit into the galactic evolutionary chain. Some have suggested they start off not as galaxies but as giant star clusters. The latest results on M60-UCD1 challenge that idea. The new Chandra data indicate that there may be a supermassive black hole at the center of M60-UCD1. If that’s the case, then it’s unlikely this object could have ever been a star cluster. Instead, the X-ray data point to this galaxy being the remnants of a larger galaxy that had its outer stars ripped away by tidal forces, leaving behind the dense inner core of the galaxy. Other information about M60-UCD1 including its large mass, point to the same conclusion. Regardless, this galaxy is a fascinating object that astronomers will be studying for a long time to come.

3-D Printing in Zero Gravity

Published on Aug 12, 2013

The goal of 3-D printing is to take this capability to microgravity for use on the International Space Station. In space, whatever astronauts have available on orbit is what they have to use — but just like on Earth, parts break or get lost. When that happens, there’s a wait for replacement parts, or the need to have multiple spares that have to be launched. The ability to conduct 3-D printing in space could change all of that.

Saturn V F-1 Engine Gas Generator Blazes Back To Life

Published on Jan 15, 2013

On Jan. 10, 2013, a resurrected gas generator from a Saturn V F-1 engine completed two hot-fire tests that are part of a series of tests at Test Stand 116 located in the East Test Area at NASA’s Marshall Space Flight Center in Huntsville, Ala. The primary test objectives are to gather performance data from the refurbished gas generator and to demonstrate new test stand capabilities for conducting future tests with liquid oxygen and rocket grade kerosene fuel. Data from the tests will benefit the development of advanced, affordable propulsion systems needed for the evolved Space Launch System heavy-lift rocket — a launch vehicle designed to carry 130 metric tons (143-tons) and to send humans even farther than the moon.

Mars Landscape

Published on Aug 3, 2012

Spacecraft have studied the Martian surface for decades, giving Earthlings insights into the history, climate and geology of our nearest neighbor, Mars. These images are from ‘Mars Landscape,’ a virtual exhibit THAT commemorates the landing of the Mars Science Laboratory (MSL) Curiosity rover at Gale Crater on August 5, 2012 and features actual images sent back by surface rovers and spacecraft from NASA and the European Space Agency. The brilliant, but false, colors in many of these images represent temperature differences reflecting or radiating from surface material. Selected for their aesthetic rather than scientific value, these isolated observations are just preliminary studies for the landscapes that the Curiosity rover promises and they tease us to further explore the beauty that exists elsewhere in our solar system.

Solar Sail Readies for Early Warning Mission

Uploaded on Dec 9, 2011

NASA’s Solar Sail project, directed by L’Garde of Tustin, Calif., plans to take this innovative technology beyond Earth’s orbit. The spacecraft will have a “sail” one quarter the size of a football field and park in a pseudo LaGrange point closer to the sun to double the current warning period for dangerous solar flares. Slated for launch in late 2014, the instrument aboard the solar sail craft will use the sun’s photon radiation to gently offset the corresponding pull of the sun’s gravity.
