September 1, 1910: Glenn H. Curtiss made a return flight from Cedar Point in Sandusky, Ohio to Euclid Beach in Cleveland in an hour and forty-two minutes. While he did not break his August record for the longest flight over water, he did average around fifty-five miles per hour in his biplane, securing the record for the reverse course. He beat a brace of homing pigeons released just before he left Cedar Point.

85 Years Ago

September 3, 1925: The U.S. Navy dirigible Shenandoah, the United States’ first rigid airship and the first major airship to be filled with helium, crashed near Ava, Ohio, killing 14 of the 43 people aboard. Small pieces of the wrecked airship were salvaged at the Ohio site by curiosity seekers. The Shenandoah took its name from an Indian word meaning “Daughter of the Stars,” and was the first airship to use non-inflammable helium instead of flammable hydrogen.

65 Years Ago

September 20, 1945: The British Gloster Meteor made its historic first flight with Rolls Royce Trent-engines that had five-bladed propellers. The plane was not only the first operational British jet fighter, and the only Allied jet fighter to see combat in World War II, but it also pioneered turboprop power.

September 22, 1950: Col. David C. Schilling and Lt. Col. William Ritchie flew two Republic F-84E jet fighters across the Atlantic ocean nonstop. Col. Ritchie was forced to bail out over Newfoundland, but Col. Schilling flew from London to New York with three in-flight refuelings, making his journey the first nonstop jet flight across the Atlantic. The flight explored the feasibility of rapidly moving large numbers of jet fighters across the Atlantic.

50 Years Ago

September 8, 1960: The Office of Naval Research announced that radio signals had been received from the planet Saturn and a star 3,000 light-years away by the University of Michigan's 85-foot radio telescope. At the time of its construction in 1958, it was one of the largest radio telescopes in the world. Later advances in radio telescopes and NASA space missions helped to clarify the natural sources of these signals.

September 19, 1960: NASA successfully launched its Nuclear Emulsion Recovery Vehicle (NERV) experiment from Point Arguello, Calif., via an Argo D-8 rocket. The first NASA launch at the Pacific Missile Range, the NERV instrumented capsule reached an altitude of 1,260 miles before landing 1,300 miles downrange where it was picked up by U.S. Navy ships. It was the first manmade object to travel to such an altitude in space and be recovered upon its return to Earth.

September 7, 1995: NASA launched space shuttle Endeavour (STS-69) from NASA’s Kennedy Space Center, Fla. Mission highlights include the first deployment and retrieval of two satellites on the same mission, the SPARTAN 201 and Wake Shield Facility (WSF) satellite. The SPARTAN 201 was a free-flying satellite designed to investigate the solar wind that constantly flows past Earth. It was the second flight of the WSF, a commercial satellite designed to manufacture extremely pure materials in low earth orbit.

10 Years Ago

September 8-20, 2000: NASA launched space shuttle Atlantis (STS-106) from NASA’s Kennedy Space Center, Fla. The Atlantis astronauts prepared the International Space Station for arrival of the first permanent crew by delivering supplies (more than 6,000 pounds of material) and installing batteries, a toilet, power converters and a treadmill. During a space walk the crew connected power, data and communications cables to the Zvezda Service Module.

PASADENA, Calif. –The seven-month upgrade to the historic "Mars antenna" at NASA's Deep Space Network site in Goldstone, Calif. has been completed. After a month of intensive testing, similar to the rehabilitation stage after surgery, the antenna is now ready to help maintain communication with spacecraft during the next decade of space exploration.

The month of October was used as a testing period to make sure the antenna was in working order and fully functional, as scheduled, for Nov. 1. A team of workers completed an intense series of tasks to reach its first milestone – upgrading the 70-meter-wide (230-foot-wide) antenna in time to communicate with the EPOXI mission spacecraft during its planned flyby of comet Hartley 2 on Nov. 4.

The first official demonstration space track was on Sept. 28, when the antenna communicated with NASA's EPOXI mission spacecraft.

"We've been testing the antenna since Sept. 28, and we've had no problems in tracking the spacecraft," said Peter Hames of NASA's Jet Propulsion Laboratory, Pasadena, Calif., who is responsible for maintaining the network's antennas. "We are ready to resume service as scheduled." JPL manages the Deep Space Network for NASA.

During the upgrade process, workers raised a portion of the antenna that weighs 3.2 million kilograms (7 million pounds) up from the base by 5 millimeters (0.2 inches) while they performed a precise, delicate repair. They replaced a portion of the hydrostatic bearing (enabling the antenna to rotate horizontally) and the four elevation bearings (enabling the antenna to track up and down from the horizon).

Unlike the sterile confines of an operating room, this surgery took place in the middle of California's Mojave Desert, a hot oasis baked by the unforgiving desert heat. The team members were able to cheat the heat by completing a number of the 375 tasks during early morning and night shifts. The tasks required the team to analyze, load, lift, install, test, analyze again and inspect.

The Deep Space Network consists of three deep-space communication facilities positioned approximately 120 degrees of longitude apart. In addition to the Mojave Desert location at Goldstone, the other locations are outside of Madrid, Spain, and Canberra, Australia. Each 70-meter (230-foot) antenna is capable of tracking a spacecraft traveling more than 16 billion kilometers (10 billion miles) from Earth. The antennas are strategically situated at each location in semi-mountainous basins to reduce radio frequency interference. This careful placement helps make the Deep Space Network the largest and most sensitive science telecommunications system in the world.

In March 1966, the antenna, officially known as Deep Space Station 14, earned its nickname as the Mars antenna because its first-ever signal came from NASA's Mariner 4 mission to Mars. The historic dish is now responsible for tracking an entire fleet of missions, including the rovers Spirit and Opportunity currently on the surface of Mars, the Cassini orbiter at Saturn, the twin Voyager spacecraft in the outer reaches of our solar system, and the Spitzer Space Telescope, which observes stars, galaxies and other celestial objects.

"We are nearing the completion of a very challenging engineering effort that will extend the life of one of the DSN's workhorses, making it more available and reliable in returning critical science data through at least 2025," said Wayne Sible, the network's deputy project manager at JPL.

The antenna upgrade was a collaborative effort between JPL, Diani Building Corp., Santa Maria, Calif., and ITT Corp., White Plains, N.Y. Their shared goal was to emerge from the "operating room" with a healthy patient.

"The 70-meter antenna gets under your skin, everyone involved in this project was so passionate about it, from the grout workers to the machine shops to the guys on the antenna, everybody was giving it their absolute all," said Hames.

JPL, a division of the California Institute of Technology in Pasadena, manages the Deep Space Network for NASA Headquarters, Washington.

Overview of the American Recovery and Reinvestment Act of 2009 (Recovery Act)

The American Recovery and Reinvestment Act of 2009 (Recovery Act) was signed into law by President Obama on February 17th, 2009. It is an unprecedented effort to jumpstart our economy, create or save millions of jobs, and put a down payment on addressing long-neglected challenges so our country can thrive in the 21st century. The Act is an extraordinary response to a crisis unlike any since the Great Depression, and includes measures to modernize our nation's infrastructure, enhance energy independence, expand educational opportunities, preserve and improve affordable health care, provide tax relief, and protect those in greatest need.

Implementing the Recovery Act at NASA

Among the key purposes of the Recovery Act are preserving and creating jobs, spurring technological advances in science and health, and promoting economic recovery. NASA has an important role to play in achieving these purposes through the program and facilities investments it will make with Recovery Act funding. As NASA develops and begins implementing its plans, this site will be one of the Agency's primary ways for communicating NASA's plans, progress, and results.

The President and Congress are committed to spending these recovery dollars with an unprecedented level of transparency and accountability so Americans know where their tax dollars are going and how they are being spent. Meeting these commitments will require sustained focus by all of us at NASA, particularly in planning, awarding, managing, and overseeing the contracts and grants through which the objectives of the Recovery Act will be achieved.

Recovery.gov is a website that empowers Citizens to hold the government accountable for every dollar spent. NASA, along with every other federal agency, is required to provide spending and performance data on a weekly, monthly, quarterly, and as required basis.

We invite you to visit us regularly and hear about the exciting work NASA is doing to contribute to America's economic recovery.

Agency Plans and Reports

By the end of April, NASA will be working with Congress and the Office of Management and Budget to finalize its Recovery plans. As these plans are approved and they are implemented, we will be posting the latest Agency Plans and Reports here.

NASA researchers have created an online resource that dramatically changed how the agency fosters collaborative research. In this new innovative method capitalizing strengths of the Internet, scientists can share information about systems health and data mining while aiming to help improve aviation safety in ways never before possible.

The web site is called Dashlink. DASH stands for Discovery in Aeronautics Systems Health. The name hints at the identity of the particular group of scientists who created this online gathering place in 2008. The site has more than 410 registered users.

"The primary goal of Dashlink is to disseminate information on the latest data mining and systems health algorithms, data and research," said Ashok Srivastava, principal investigator for NASA's Integrated Vehicle Health Management Project at the agency's Ames Research Center in California.

Integrated vehicle health management, or IVHM, involves technologies designed to monitor all the different systems that enable an aircraft to fly. IVHM technologies are sensors and software applications that work in concert to detect and address potential problems with an aircraft before the problems become serious.

To be effective, IVHM requires new software programs that can record and analyze instantly many variables such as temperature, pressures, stresses, and even cockpit switch positions.

Also needed are new computer algorithms, which are sets of mathematical rules used by the computers to make decisions on how to solve a problem given a certain set of data.

Dashlink allows researchers, whether inside or outside NASA, who are working on a particular software application to share the applications they have written, test each other's work, and openly discuss the results.

"It’s totally different from how other projects are run," Srivastava said, noting that the usual form of communication among scientists is published papers, which can take months to distribute and offer no immediate interaction with the author.

Interaction is important because a staple of scientific research is the ability of one group of scientists to duplicate the work of another group and achieve the same results. In the data mining field, duplicating results can be difficult and infrequent.

"We realized that the best way to validate our work was to put it out there for others to review, check our work and see what's going on. Now we have a community of researchers across the country working together and interacting with each other," Srivastava said.

Dashlink is available to anyone with an interest in integrated vehicle health management software and sensor applications. Those outside NASA can join if a NASA civil servant sponsors the registration. That is what Suratna Budalakoti did when he joined the site in September 2008.

Then a student at the University of California Santa Cruz, he collaborated with Srivastava and others in writing a data mining algorithm called Sequence Miner and used Dashlink to communicate remotely with other researchers – something he continues to do today.

"Dashlink enables open and quick exchange of ideas, data and software. It makes the process of knowledge sharing convenient and fast," Budalakoti said.

As of July 2010, Dashlink had 16 algorithms posted to it, as well as 10 different datasets available for study.

In posting these programs and datasets in a public environment, all of NASA's policies and procedures related to privacy protection, proprietary rights and the transfer of technology are being followed to the letter, Srivastava said.

"If a user wants to put up something they have to certify they've followed the instructions for posting. Users also can flag inappropriate content, but we've never had that problem," Srivastava said. "We’re very happy with the size of the community."

And now the online research community is set to expand.

Researchers from other NASA organizations such as the Earth Sciences Division are eyeing Dashlink's features. The Earth Sciences Division is planning its own Web site to facilitate the same sort of peer-to-peer interaction, said Elizabeth Foughty, the current Dashlink team lead.

In fact, the programmers behind Dashlink and the new Web site already are collaborating to create a single computer platform from which both sites can operate sharing the same code and functionality.

With the introduction of the new cross-discipline collaboration platform expected "sometime soon," Foughty said, Dashlink will get a facelift and have additional interactive features enabled. The new platform will allow other NASA science disciplines to create and roll out quickly their own collaborative Web sites.

"Our hope is that this new capability for researchers to access NASA resources and collaborate with each other will hasten and spur the kind of innovation needed to solve our future challenges in aviation and space," Foughty said.

(NASA / Tony Landis) After undergoing a major overhaul and upgrades, the Boeing / NASA X-48B Blended Wing Body research aircraft resumed flight tests with a checkout flight Sept. 21 from NASA's Dryden Flight Research Center at Edwards Air Force Base, Calif.

The subscale, manta ray-shaped, remotely piloted airplane, also called a hybrid wing body, is a tool of NASA's new Environmentally Responsible Aviation, or ERA, project. ERA aims to develop the technology needed to create quieter, cleaner, and more fuel-efficient airplanes for the future.

After completion of its first phase of flight testing, the airplane was disassembled for a complete inspection and refurbishment. This new series of flight tests will focus on additional parameter identification investigations following installation and checkout of a new flight computer. The parameter identification work will evaluate the new computer’s control of the aircraft’s flight control surfaces and the airplane's performance.
