A PLACE WHERE STARS COME FROM

A Nearby Stellar Cradle
The Milky Way and other galaxies in the universe harbor many young star clusters and associations that each contain hundreds to thousands of hot, massive, young stars known as O and B stars. The star cluster Cygnus OB2 contains more than 60 O-type stars and about a thousand B-type stars. Deep observations with NASA’s Chandra X-ray Observatory have been used to detect the X-ray emission from the hot outer atmospheres, or coronas, of young stars in the cluster and to probe how these fascinating star factories form and evolve. About 1,700 X-ray sources were detected, including about 1,450 thought to be stars in the cluster. In this image, X-rays from Chandra (blue) have been combined with infrared data from NASA’s Spitzer Space Telescope (red) and optical data from the Isaac Newton Telescope (orange).

COLLISION OF A GALACTIC PROPORTION

FROM: NASASpacecraft Image Mashup Shows Galactic Collision

This new composite image from the Chandra X-ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope shows two colliding galaxies more than a 100 million years after they first impacted each other. The continuing collision of the Antennae galaxies, located about 62 million light years from Earth, has triggered the formation of millions of stars in clouds of dusts and gas

THE U.S. AIR FORCE AND THE NEAR SPACE JUMP

FROM: U.S. AIR FORCE
AFRL played major role in historic near-space jump
11/2/2012 - KIRTLAND AFB, N.M (AFNS) -- For more than nine minutes Oct. 14, an international audience watched as Austrian daredevil Felix Baumgartner egressed from a capsule 128,000 feet above the earth and fell toward the planet reaching speeds of 834 miles per hour, to become the first person to break the sound barrier outside of a vehicle.

When Baumgartner safely touched down 33 miles east of Roswell, N.M., shortly before noon, he had also achieved another milestone, topping Air Force Col. Joe Kittinger's 52-year-old record of the highest free fall by 25,200 feet.

The historic event would not have occurred without the significant participation of the Air Force Research Laboratory's Space Vehicles Directorate and one of its contractors, ATA Aerospace.

Five years ago, Red Bull Stratos, which sponsored Baumgartner's near-space jump, approached the directorate about supporting the mission, but the Kirtland-based organization's officials did not believe the activity had enough of a science and technology perspective, so they passed on it. About 18 months later, the directorate decided to assist the proposed mission, with the reversal attributable to a cooperative research and development agreement signed between the agency and ATA Aerospace.

"The agreement with ATA Aerospace allows a commercial company to use our facilities, evaluate equipment and conduct testing. It is a good way to offset costs and take advantage of excess capacity of both the facilities and equipment," said Harold "Vern" Baker, chief, Space and Integration Test Branch, Integrated Experiments and Evaluation Division, AFRL's Space Vehicles Directorate. "We realized that under the CRADA, we should be able to assist Baumgartner's jump and allow ATA to use our launch equipment for our high-altitude balloon program."

For Red Bull Stratos' two unmanned flights and the three manned missions (Baumgartner's two test jumps and his record-breaking decent), on-site ATA Aerospace staff performed liftoff and capsule-retrieval functions with the support and expertise of AFRL staff members Ed Coca, balloon launch director, and Baker, who ensured pre-and post-operations procedures had been conducted safely and properly. A 20-plus year veteran of the Air Force high-altitude balloon program, Baker watched Baumgartner's historic jump from mission control at the Roswell International Air Center.

"The balloon, which took Felix's capsule to 128,000 feet, was filled with 30 million cubic feet of helium," Baker said. "After about an hour delay due to winds, the balloon lifted off shortly after 9:30 a.m., for a two-and-a-half hour journey to the egress point. During that time, Felix's visor was not defrosting and there was concern the mission would have to be aborted."

Despite the defrost problem, the flight was not aborted and in-flight troubleshooting was attempted instead.

"The visor eventually defrosted from power in his suit, so after about 15-20 minutes, Baumgartner leapt from the capsule," Baker recalled."Several seconds into the free fall, he began to flat spin and there was a lot of concern in mission control, but he suddenly stabilized. He was also close to blacking out, but if that would have occurred, a drogue parachute would have been deployed. Those of us in Mission Control roared when Felix landed on the ground safe and sound."

ATA Aerospace employee Tracy Gerber, who has worked at the directorate since 1995 and has participated in many high-altitude balloon launches, said the opportunity to play a significant role in, and witness Baumgartner's leap into the history books, has been a career highlight.

"We've done a number of launches over the years, but none of them, in my opinion, compare to the one we did Oct. 14 with Red Bull Stratos and Sage Cheshire Aerospace, who built the capsule, and also the David Clark Company, which makes all the balloon suits for the NASA program did the one for Felix as well," said Gerber, Space Technology Research and Integrated Vehicle Experiments deputy program manager, in support of the Space Vehicles Directorate's Space Integration and Test Branch. "Getting to work with all these organizations was an incredible experience. Finally, from Oct. 23 to 28, I had the unique opportunity to attend a post-mission event in Salzburg, Austria, sponsored by Red Bull Stratos, to recognize all those involved in Felix's record-breaking jump."

In preparation for the big day, Baker arrived on scene late Saturday and then after discussions with three operations managers, including Gerber, he and Coca directed the helium inflation of the balloon at about 3 a.m. Shortly before 6 a.m., Baumgartner entered the 2,900-pound capsule. Three and half hours later, he began his ascent at a rate of about 1,000 feet per minute. The rest is history.

"Our expertise, our contract support and the contractor expertise we've developed played a huge part in Felix's successful mission," said Baker. "ATA Aerospace spent a lot of time, effort and money putting together all the procedures, processes and countdowns, and deserves much of the credit in making the record-shattering event happen. Although Felix was the main focus and rightly so, it took a team of dedicated and determined individuals to ensure it was mission possible."
