His departure ends a 22-year career with NASA that began in 1990 as a project engineer in the Marshall space shuttle project integration office.
Goldman has been the acting center director at Marshall since March 5 when Robert Lightfoot began his assignment as NASA acting associate administrator at NASA Headquarters. Previously, beginning March 2010, Goldman served as the center's deputy director.
"Gene's technical expertise and management skills will be missed, not only at Marshall, but across the entire agency," said NASA Administrator Charles Bolden. "We are grateful for his service to NASA and wish him the best in his next endeavor."
Goldman describes his time at NASA as the finest in his professional career.
"Working for NASA and supporting the Space Shuttle Program was a dream come true for me," said Goldman. "It has been an honor and a privilege to work on NASA's human spaceflight programs, both at Marshall and across the agency for more than two decades."
Prior to his most recent posts at Marshall, Goldman served as the director of the Stennis Space Center from 2008 until 2010 and deputy director at Stennis from 2006 to 2008.
"I believe the center is in a great position from the spaceflight and science programs we have," said Goldman during an all-hands meeting July 9 with Marshall team members. "So I'm leaving on a good note."

NASA's Space Launch System Integration Team Aims to 'Beat the Schedule'
By Amie Cotton and Bill Hubscher
While the Space Launch System, or SLS, is still in the early design process, one of the critical elements is already under construction at the Marshall Space Flight Center and will fly on the first Orion spacecraft test flight in two short years.

When NASA flies the Orion module on Exploration Flight Test 1, known as EFT-1, in 2014, designers and engineers will record reams of data about its performance, from launch and flight, to re-entry and landing. A Delta IV rocket operated by United Launch Alliance at the Kennedy Space Center will propel the capsule into space. However, because the Delta rocket was not originally designed and built to launch Orion, engineers with the SLS Spacecraft & Payload Integration team at the Marshall Center are building innovative adapter hardware to connect the two. This same hardware design will be used on the flexible configurations of the SLS.
"Our entire team is excited to come to work every day because we're building the hardware that will actually fly," said David Beaman, spacecraft and payload integration manager for the SLS program. "We have the unique opportunity to design this hardware early and provide it for Orion's flight test, saving time and money in a few different ways. We took less than a month to pull together an approved drawing and design for the aluminum integration rings and have passed several major milestones. By designing the adapter for both missions, we provide an affordable solution to keep our human exploration mission moving forward. It's a great collaboration between our two programs."

The designers of the SLS adapter rings are using a unique Marshall Center capability to save on schedule and cost. The master machinists in the Mechanical Fabrication Branch of the Space Systems Department are using the world's largest multi-axis milling machine to build the ring prototypes in Building 4705.
"By leveraging the state-of-the-art, one-of-a-kind milling machine installed at the Marshall Center for building hardware, there's going to be a cost savings," said Patrick Hull, the multi-purpose crew vehicle/stage adapter lead designer for SLS. "The manufacturing team who run this facility are demonstrating their ability to produce large-scale flight hardware built in-house."

Even the aluminum material used to create the prototypes of the integration rings is a good example of economic savings through recycling.
"We've taken an existing ring that was forged in a fixed diameter and made a smaller ring out of it to meet our needs," said Brent Gaddes, adapter subsystem manager with SLS. "This proof-of-concept also was delivered ahead of schedule and we're excited about the progress we're making. By delivering them early, we have more time to double and even triple-check our process and design."

When the Orion spacecraft takes its first real test flight in 2014, it will travel 3,600 miles into space -- 15 times farther away from Earth than the International Space Station.
"When you fly a vehicle for the first time you want to know as much as possible and the EFT-1 mission will allow our SLS team to learn about the structural, mechanical and electrical interfaces -- the internal environment between Orion and the launch vehicle," said Garry Lyles, chief engineer for the Space Launch System at Marshall. "Our team will capture flight data that will be useful to calibrate guidance, navigation and control algorithms and structural loads for SLS; separation dynamics between Orion and the launch vehicle; and overall vehicle stability -- all vital data to reduce risk and increase reliability and sustainability for America's next launch vehicle."

Orion will carry astronauts farther into space than ever before, sustaining the crew during space travel and providing emergency abort capability and safe re-entry from deep space. Orion will launch atop the SLS, NASA's next flagship rocket currently under design. The SLS will power the Orion spacecraft on deep space missions to asteroids, the moon, Mars and other destinations in our solar system. The first flight test of the full-scale SLS is planned for 2017.
The first SLS mission, Exploration Mission 1, in 2017 will launch an uncrewed Orion to demonstrate the integrated system performance of the SLS rocket and spacecraft prior to a crewed flight. The second SLS mission, Exploration Mission 2, is targeted for 2021 and will launch Orion and a crew of up to four American astronauts.

Has the Speediest Pulsar Been Found?
NASA news release
Researchers using three different telescopes -- NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton in space, and the Parkes radio telescope in Australia -- may have found the fastest moving pulsar ever seen.
The evidence for this potentially record-breaking speed comes, in part, from the features highlighted in this composite image. X-ray observations from Chandra (green) and XMM-Newton (purple) have been combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey (colored red, green and blue, but appearing in the image as white).
The large area of diffuse X-rays seen by XMM-Newton was produced when a massive star exploded as a supernova, leaving behind a debris field, or supernova remnant known as SNR MSH 11-16A. Shock waves from the supernova have heated surrounding gas to several million degrees Kelvin, causing the remnant to glow brightly in X-rays.
The Chandra image shown in the inset ("X-ray close-up") reveals a comet-shaped X-ray source well outside the boundary of the supernova remnant. This source consists of a point-like object with a long tail trailing behind it for about three light years. The bright star nearby and also the one in SNR MSH11-16A are both likely to be foreground stars unrelated to the supernova remnant.
The point-like X-ray source was discovered by the International Gamma-Ray Astrophysics Laboratory, or INTEGRAL, and is called IGR J11014-6103, or IGR J11014 for short. It may be a rapidly spinning, super-dense star -- known as a "pulsar", a type of neutron star -- that was ejected during the explosion. If so, it is racing away from the center of the supernova remnant at millions of miles per hour.
The favored interpretation for the tail of X-ray emission is that a pulsar wind nebula, that is, a "wind" of high-energy particles produced by the pulsar, has been swept behind a bow shock created by the pulsar's high speed. (A similar case was seen in another object known as PSR B1957+20 (http://chandra.harvard.edu/photo/2003/b1957/closer_look.html
The elongated emission is pointing toward the center of MSH 11-61A where the pulsar would have been formed, supporting the idea that the Chandra image is of a pulsar wind nebula and its bow shock. Another interesting feature of the Chandra image, also seen with XMM-Newton, is the faint X-ray tail extending to the top right. The cause of this feature is unknown, but similar tails have been seen from other pulsars that also do not line up with the pulsar's direction of motion.
Based on earlier observations, astronomers estimate that the age of MSH 11-61A is approximately 15,000 years, and it lies at a distance of about 30,000 light years away from Earth. Combining these values with the distance that the pulsar has appeared to have traveled from the center of the MSH 11-61A, astronomers estimate that IGR J11014 is moving at a speed between 5.4 million and 6.5 million miles per hour.
The only other neutron star associated with a supernova remnant that may rival this in speed is the candidate found in the supernova remnant known as G350.1-0.3. The speed of the neutron star candidate in this system is estimated to lie between 3 and 6 million miles per hour (http://chandra.harvard.edu/photo/2012/g350/
). The high speeds estimated for both IGR J11014 and the neutron star candidate in G350.1-0.3 are preliminary and need to be confirmed. If they are confirmed, explaining the high speeds of the neutron star presents a severe challenge to existing models for supernova explosions.
One important caveat in the conclusion that IGR J11014 may be the fastest moving pulsar is that pulsations have not been detected in it during a search with the Commonwealth Scientific and Industrial Research Organization Parkes radio telescope. This non-detection is not surprising for a pulsar located about 30,000 light years away.
However, there are other pieces of evidence that support the pulsar interpretation. First, the lack of detection of a counterpart to the X-ray source in optical or infrared images supports the idea that it is a pulsar, since such objects are very faint at these wavelengths. Also, there are no apparent differences in the brightness of the source between XMM-Newton observations in 2003 and the Chandra observations in 2011, behavior that is expected if IGR J11014 is a pulsar. Finally, the X-ray spectrum of the source, that is, its signature in energy, is similar to what astronomers expect to see for a pulsar.
These results were published in the May 10 issue of The Astrophysical Journal Letters. The authors were John Tomsick and Arash Bodaghee of the University of California, Berkeley; Jerome Rodriguez and Sylvain Chaty of the University of Paris, CEA Saclay; Fernando Camilo of Columbia University; Francesca Fornasini of UC Berkeley; and Farhid Rahoui of the Harvard-Smithsonian Center for Astrophysics.

The program's graduation featured presentations by each SELDP participant to the NASA Engineering Management Board, observations by Boeing Chief Engineer Paul Lambertson on the differences and similarities of systems engineering across government and industry, and a visit from NASA Administrator Charlie Bolden.
The graduation week marked the culmination of a yearlong program that provided participants with knowledge, skills and experiences aimed at preparing them for the challenges of systems engineering leadership at NASA. After a rigorous application process, the program kicked off in the spring of 2011. Once participants completed baseline assessments to identify strengths and areas for development, they embarked on a year of learning, developing and practicing the qualities of a systems engineering leader: creativity, curiosity, self-confidence, persistence and an understanding of human dynamics.
Program activities included mentoring and coaching, technical training, leadership development exercises and forums. The 2012 SELDP class also conducted benchmarking exercises at organizations including Boeing, Costco and Blue Origin.
The core of the SELDP experience was a hands-on developmental assignment at a new center. Participants took on systems engineering roles that expanded their experience base and challenged them to incorporate new knowledge and skills in an unfamiliar organizational setting.
Travis Martin -- Marshall's high-speed data acquisition systems engineer, and a design and manufacturing engineer -- was assigned to the Jet Propulsion Laboratory and served as the assistant to the lead project systems engineer on the Soil Moisture Active Passive, or SMAP, program.

Bob Williams, a Marshall systems engineer, went to NASA Headquarters where he served as the lead for Exploration Systems Development, or ESD, Technology Investments on ESD, Cross-Program Systems Integration.
NASA Chief Engineer Mike Ryschkewitsch congratulated the class on completing the program. "You're no longer the expert in electrical engineering or materials," he said. "What [your team needs] to know is that you can listen to them all and adjudicate them." He shared insight into his own career, making tough decisions, and leading a team. "You are going to be trusted repeatedly over the course of your careers with a big responsibility," he added. "You're being asked to lead people and you will need to ask, what do they need from you?"
SELDP grew out of a need identified by NASA leadership and the Office of the Chief Engineer for an agency-wide leadership development program that would help identify and accelerate the development of high-potential system engineers, with a focus on specific leadership behaviors and technical capabilities that are critical to success in the NASA context. Headed by Christine Williams of the NASA Academy of Program/Project & Engineering Leadership, known also as APPEL, SELDP aims to develop and improve leadership skills and technical capabilities.
