Mars scientists hoped they would have a better idea of when and how they would get samples back from Mars after NASA completed an internal study of the Mars Sample Return program. Instead, as Jeff Foust reports, NASA is now turning to industry for help on how to reduce the costs and accelerate the schedule of MSR.

In the 1970s, US intelligence analysts were concerned about Soviet lasers intended to illuminate American satellites. Dwayne Day examines how the CIA attempted to study those efforts with a telescope in Iran, only to be thwarted by the revolution there.

China is scheduled to launch later this week Chang'e-6, the first mission to attempt to return samples from the far side of the Moon. Carlos Alatorre explores what is driving the country's efforts to go to lunar farside and bring back samples.

NASA sent its final commands to the Ingenuity Mars helicopter last week, three months after the helicopter's final flight. Will Pomerantz describes the remarkable achievements of Ingenuity and its influence on future missions.

Earlier this month NASA announced a new Space Sustainability Strategy that outlines how the agency would address the growing threats posed by orbital debris. Jeff Foust reports on the strategy, which initially emphasizes getting a grasp on the problem rather than technological solutions.
