NASA announced on Monday that it will exercise options to purchase two additional flights on Boeing's Starliner spacecraft, as well as financially support the company in its efforts to return the crewed vehicle to flight and find a new rocket after the Atlas V vehicle retires.

The space agency's announcement confirms reporting by Ars Technica earlier this month on NASA's plans to maintain access to low-Earth orbit after the impending retirement of SpaceX's Crew Dragon vehicle.

"I do not think it's a secret that SpaceX intends to sunset older platforms like Falcon and Dragon as they concentrate on their next-generation capability, Starship," NASA Administrator Jared Isaacman said during a news conference on Monday afternoon.

Recently, the astronauts on board the International Space Station performed a routine "walk-off" maneuver with the large, 58-foot-long robotic arm attached to the orbiting laboratory.

The robotic arm, known as Canadarm2 because it was supplied by the Canadian Space Agency, is something of a modern engineering miracle—it can effectively move around the exterior of the large space station like an inchworm because both ends are essentially identical.

However, after this particular walk-off maneuver, the robotic arm, along with the mobile transporter that guides it along the main truss of the space station, engineers noted some issues with operations.

The first in a new class of space telescopes is on track to reach the launch pad in the early 2030s, NASA announced this week.

The PRIMA mission will be the first of NASA's Probe Explorers, a new line of observatories intended to do more science for less money. The agency's space telescopes typically fall into lower-cost "Explorer-class" missions, with cost caps in the range of a few hundred million dollars, or flagship observatories like the recently launched Nancy Grace Roman Space Telescope, which came with a price tag of some $4.3 billion.

With the Probe Explorers, NASA officials seek to find a better balance between the smaller Explorer missions and multibillion-dollar flagships. NASA has studied potential Probe Explorer mission concepts for several years after an independent panel of scientists recommended the new mission category. But it wasn't clear until recently whether NASA's science budget, which is under pressure from the Trump administration, would be sufficient to actually start developing one.

Did you know that the first character that Walt Disney created to specifically appear on television was inspired, in part, by early Space Age rocket scientists?

On this day 65 years ago (September 24, 1961), Disney introduced the "renowned scientist, lecturer, psychologist [and] world traveler," Ludwig Von Drake. A member of the Duck family (he is the "brilliant and eccentric" uncle of Donald Duck), Von Drake was "the outstanding genius of the century" (per Disney himself) who helped to explain scientific principles and technological concepts to the millions of people who tuned in every Sunday to watch Walt Disney's Wonderful World of Color on NBC.

A few years later, after expertly (but often absent-mindedly) addressing topics such as how color television works, the health benefits of exercising, and the history of aviation, Von Drake dove into the topic for which he said he wrote the book on, in the February 10, 1963, episode "Inside Outer Space."
