NASA administrators are also accountable to elected officials. Administrators are appointed by the president but must be confirmed by the Senate. Congress has a great deal to say about the budget that NASA gets each year. They also must authorize major programs, like the Artemis program, which aims to return the U.S. and its partners to the moon.

NASA's Parker Solar Probe is expected to make a fiery dive close to the solar surface on the morning of Christmas Eve.

With humans slated to return to the moon this decade, NASA has been testing new lunar vehicles in simulated low gravity.

Suni Williams and Butch Wilmore won't be back on Earth before March, but they've got candy canes and Santa hats to celebrate the holiday.

Let's set the record straight: NASA has not found a parallel universe. The claims making the rounds on social media are not based on new scientific findings but are instead a distorted interpretation of older research.

The transition team has been grappling with an agency that has a superfluity of field centers—ten spread across the United States, as well as a formal headquarters in Washington, DC—and large, slow-moving programs that cost a lot of money and have been slow to deliver results.

NASA's Parker Solar Probe flew closer to the sun than any human-made object ever — a stunning technological feat that scientists liken to the historic Apollo moon landing in 1969.

Space missions to the moon, Mars and beyond often get the most attention, but NASA's Near Space Network does a lot of heavy lifting for humankind's reach for the stars.

NASA's first two crewed Artemis moon missions have been pushed back to 2026 and 2027, respectively, and the move could have big ramifications for the agency's Artemis program and competition with China for leadership in space.
