Former Employees

The post-government employment ethics statute, 18 U.S.C. § 207, applies to a former NASA employee’s communication with NASA or the Government on behalf of the former employee’s non-federal employer. Former NASA employees should contact a NASA ethics official for advice before communications or otherwise interacting with NASA or the Government on behalf of their new employer because this criminal statute may be implicated.  The Procurement Integrity Act also restricts individuals who were in certain contracting roles from accepting compensated work from certain contractors for a limited period. 

Contact Information

If you have questions, please ask an ethics official at your respective center.

Special Government Employees

A Special Government Employee (SGE) is an officer or employee “who is retained, designated, appointed, or employed to perform, with or without compensation, for not to exceed one hundred and thirty days during any consecutive period of three hundred and sixty-five consecutive days.” 18 U.S.C. § 202. Congress created the SGE category in 1962 to allow the federal Government to obtain the expertise it needs, while allowing experts to continue their private professional lives. As a result, some of the ethics statutes and regulations apply differently to SGEs than they do to regular executive branch employees, and some provisions do not apply at all.

Financial Disclosure

SGEs are required to file a financial disclosure report each year, usually a confidential financial disclosure report (OGE-450). Financial disclosure reporting helps NASA identify any possible financial conflicts of interest. SGEs are notified in advance of when to file.

Ethics Training

SGEs are required to receive annual ethics training by December 31st of each calendar year.

Contact Information

If you are a SGE and have questions, please contact the Headquarters Ethics Team by e-mail at hq-ethicsteam@nasa.gov or by phone at (202) 358-0550.

NASA’s X-59 Completes Electromagnetic Testing

NASA’s X-59 Completes Electromagnetic Testing

3 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

A NASA F-15 aircraft sits 20 feet off the left side of the X-59 aircraft, with a white hangar and hills in the background, during electromagnetic interference testing.
NASA’s F-15D research aircraft is positioned adjacent to the X-59 during electromagnetic compatibility testing at U.S. Air Force Plant 42 in Palmdale, California. Researchers activated the F-15D’s radar, C-band transponder, and radios at different distances from the X-59 to evaluate potential electromagnetic interference with the aircraft’s flight-critical systems, ensuring the X-59 can operate safely with other aircraft. These tests showed that the aircraft’s integration is maturing and cleared a major hurdle that moves it one step closer to first flight.
NASA/Carla Thomas

NASA’s quiet supersonic X-59 research aircraft has cleared electromagnetic testing, confirming its systems will work together safely, without interference across a range of scenarios.

“Reaching this phase shows that the aircraft integration is advancing,” said Yohan Lin, NASA’s X-59 avionics lead. “It’s exciting to see the progress, knowing we’ve cleared a major hurdle that moves us closer to X-59’s first flight.”

Electromagnetic interference occurs when an electric or magnetic field source affects an aircraft’s operations, potentially impacting safety. This interference, whether from an external source or the aircraft’s own equipment, can disrupt the electronic signals that control critical systems – similar to effects that lead to static or crackling on a radio from a nearby emitting device, like a phone.

The tests, conducted at contractor Lockheed Martin Skunk Works’ facility in Palmdale, California, ensured that the X-59’s onboard systems – such as radios, navigation equipment, and sensors – did not interfere with one another or cause unexpected problems. During these tests, engineers activated each system on the aircraft one at a time while they monitored the other systems for possible interference.

NASA’s X-59 sits partially outside a white hangar at Lockheed Martin’s Skunk Works Facility in Palmdale, California, with cables and sensors extending from its cockpit.
NASA’s X-59 quiet supersonic research aircraft successfully completed electromagnetic interference (EMI) testing at Lockheed Martin Skunk Works in Palmdale, California. During EMI tests, the team examined each of the X-59’s internal electronic systems, ensuring they worked with one another without interference. The X-59 is designed to fly faster than the speed of sound while reducing the loud sonic boom to a quieter sonic thump.
NASA/Carla Thomas

“This testing helped us determine whether the systems within the X-59 are interfering with each other,” Lin said. “It’s called a source-victim test – essentially, we activate one system and monitor the other for issues like noise, glitches, faults, or errors.”

The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA’s Quesst mission, which will provide regulators with information that could help lift current bans on commercial supersonic flight over land. Currently, the aircraft is progressing through ground tests to ensure safety and performance. These included the recent, successful completion of a set of engine tests. The electromagnetic interference testing to examine the X-59’s internal electronic systems followed.

Other electromagnetic interference testing involved the team looking at the operation of the X-59’s landing gear, ensuring this critical component can extend and retract without affecting other systems. And they tested that the fuel switch shutoff was functioning properly without interference.

Electromagnetic compatibility was also assessed during this testing – making sure the X-59’s systems will function properly when it eventually flies near NASA research aircraft.

The EMI testing ensures an aircraft’s systems function properly under various conditions of electromagnetic radiation. The X-59 is the centerpiece of the NASA’s Quesst mission, designed to demonstrate quiet supersonic technology and provide data to address a key barrier to commercial supersonic travel.
NASA/Carla Thomas

Researchers staged the X-59 on the ground in front of NASA’s F-15D, placing them 47 feet apart, then 500 feet apart. The proximity of the two aircraft replicated conditions needed for the F-15D to use a special probe to gather measurements about the shock waves the X-59 will produce.

“We want to confirm there’s compatibility between the two aircraft, even at close proximity,” Lin said.

For the electromagnetic compatibility testing, the team powered up the X-59’s engine while turning on the F-15D’s radar, C-band radar transponder, and radios. Data from the X-59 were transmitted to NASA’s Mobile Operations Facility, where control room staff and engineers monitored for anomalies.

“You want to make discoveries of any potential electromagnetic interference or electromagnetic compatibility issues on the ground first,” Lin said. “This reduces risk and ensures we’re not learning about problems in the air.”

Now that electromagnetic testing is complete, the X-59 is ready to move on to aluminum bird tests – during which data will be fed to the aircraft on the ground under both normal and failure conditions – and then taxi tests before flight.

NASA

Free flying robotics and space agriculture topped Tuesday’s research schedule as the Expedition 72 crew helps advance the space industry. The International Space Station will also see the departure of a cargo craft and the arrival of its replacement this week.

NASA’s station Commander Suni Williams began her day setting up and activating the Astrobee robotic assistant, a cube-shaped, toaster-sized technology demonstration device, inside the Kibo laboratory module. Next, she outfitted the Astrobee with tentacle-like grippers for a test of its ability to autonomously detect and capture simulated orbital debris. Afterward, ground controllers took control of Astrobee and programmed the robotic free flyer to perform maneuvers to locate a capture target then reach out and grapple the free-floating object. Researchers are testing the ability of robots to safely remove orbital debris and protect satellites.

Following the robotics demonstration, NASA Flight Engineer Don Pettit worked in Kibo installing research components on the Advanced Plant Habitat hosting growing Red Romaine lettuce. The space botany hardware divided the young plants into quadrants for observation and provided a temperature sensor device measuring leaf temperature between watering periods. Insights from the Plant Habitat-07 investigation may inform ways to grow crops on future space missions.

NASA astronauts Nick Hague and Butch Wilmore spent their day primarily focusing on science hardware, life support maintenance, and cargo transfers. Hague started his shift in the Columbus laboratory module partially uninstalling the Navigation and Communication Testbed that could provide a more accurate alternative to satellite systems for lunar navigation. Hague then powered up a pair of incubators for biology research later in the week. Wilmore began his day draining recycling tanks then loaded trash inside the Cygnus space freighter ahead of its departure next month. Wilmore wrapped up his shift installing software on a science laptop computer in the Destiny laboratory module.

Roscosmos’ Progress 89 cargo craft is poised to depart the space station at 3:17 p.m. EST today when it undocks from the Zvezda service module’s aft port completing a six-month cargo mission. It will be replaced by the Progress 91 cargo craft after it launches at 4:24 p.m. on Thursday from the Baikonur Cosmodrome in Kazakhstan. The Progress 91, carrying three tons of food, fuel, and supplies, will dock to Zvezda’s vacant port at 6:03 p.m. on Saturday where it will stay for another six months.

Cosmonauts Alexey Ovchinin and Ivan Vagner prepared on Tuesday for the Progress 91’s arrival setting up the TORU, or tele-robotically operated rendezvous unit, inside Zvezda. The TORU can be used to command and control an approaching spacecraft from Roscosmos if necessary.

Vagner then moved on and scanned cosmonaut Aleksandr Gorbunov’s eyes with the Ultrasound 2 device for a regularly schedule exam. Gorbunov also completed a 24-hour session that measured his cardiac activity and blood pressure with portable electrodes.
