The Postal Service dedicated its OSIRIS-REx stamp in Salt Lake City on Sept. 22.

The stamp commemorates the seven-year NASA mission that studied, mapped and collected a sample from the asteroid Bennu. The return of the sample to Earth on Sept. 24 marked the mission’s successful completion.

The name OSIRIS-REx is an acronym for the mission’s goals: Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer.

“I think we would all agree that this mission exemplifies the best of American innovation,” said Robert Raines, the Postal Service’s business solutions vice president, who spoke at the ceremony.

The final stage of the OSIRIS-REx mission was for the spaceship to fly by Earth and release a capsule of Bennu’s dust and rocks, which landed by parachute in the Utah desert.

Raines was joined at the ceremony by Duke Johnson, director of Clark Planetarium; Mike Puzio, a North Carolina student who won a contest in 2013 to name the asteroid; Heather Enos, OSIRIS- REx deputy principal investigator at the University of Arizona; Tim Priser, chief engineer for deep space exploration at Lockheed Martin Space; and Lori Glaze, director of NASA’s Planetary Science Division.

Bentley Pistorius, supervisor of educational programs at the Clark Planetarium, was master of ceremonies.

The stamp depicts the capsule containing the sample parachuting to Earth. The images on the pane illustrate milestones in the mission.

Antonio Alcalá, an art director for USPS, designed the stamp and pane using illustrations by Alan Dingman, who based his work on images supplied by NASA.

The Forever stamp is available in panes of 20 at Post Offices and usps.com.

The Hatch Act limits the political activities that Postal Service and other federal employees can engage in.

With election season around the corner, USPS is reminding employees of the do’s, don’ts and not-while-in-uniform rules of the Hatch Act, which limits political activity among the federal workforce.

Postal Service employees may engage in the following activities while off duty, not in uniform, not in a Postal Service vehicle, and not on USPS or other federal property:

• Register and vote as they choose;

• Assist in voter registration drives;

• Express opinions about candidates and issues;

• Be a candidate or participate in nonpartisan elections in which no candidate representing a political party is running;

• Contribute money to political campaigns, parties and partisan political groups; and

• Place signs on their personal property, though the signs cannot be in view while videoconferencing for work.

Postal Service employees may never:

• Engage in fundraising — soliciting, collecting or receiving funds — for a partisan political party, candidate for partisan political office or partisan political group;

• Host, sell tickets or invite anyone to a political fundraiser;

• Use their title or position or wear their uniform or any item identifying USPS or their position while engaged in political activity;

• Invite subordinate employees to political events or encourage their involvement in political activity; or

• Be a candidate in a partisan election (where any candidates are running in affiliation with a political party).

While on duty, in uniform, in a postal vehicle or on postal or other federal property, USPS employees may not:

• Distribute, share or post political or campaign materials;

• Wear partisan political buttons, shirts, hats and the like;

• Post, like, tweet or retweet partisan political content;

• Place a partisan political bumper sticker on a vehicle delivering mail; or

• Express opinions at work that are directed at the success or failure of a political party, candidate for partisan political office or partisan political group.

The U.S. Office of Special Counsel has more information about what federal employees can and cannot do under the Hatch Act.

• Employees can also email the USPS Ethics Office for guidance.

Keep your home emergency supply kit stocked, including drinking water and nonperishable food.

During National Preparedness Month, the Postal Service is encouraging employees to prepare or refresh their home emergency supply kit.

Such a kit is a collection of basic items to meet the needs of your family — including pets — for at least 72 hours.

These items should be packed in a portable container, such as a plastic bin or duffel bag, in the event you need to evacuate. Everyone in your household should know where the kit is kept.

At minimum, experts recommend that an emergency supply kit have the following:

• First-aid supplies;

• Medications and any needed medical items;

• One gallon of water per person, per day;

• Nonperishable, easy-to-prepare food;

• Battery-powered or hand-crank radio, flashlight and extra batteries;

• Moist towelettes, garbage bags and plastic ties;

• Wrench or pliers (to turn off utilities);

• Cellphone with chargers and a backup battery;

• Copies of personal documents (medication lists and pertinent medical information, proof of address, deed or home lease, passports, birth certificates, insurance policies); and

• Other items needed by family members and pets.
