Here are some recent stories related to NASA missions.
—PhysicsWorld: “US Astronomers Slam Cuts to the Chandra X-ray Observatory“
X-ray astronomers in the US have begun a campaign to save the Chandra X-ray Observatory from budget cuts that would effectively end the mission. They assert that the craft, which was launched in 1999, has plenty of life left in it. Cancelling support could, they say, damage scientific efforts to understand the universe and the careers of an emerging generation of X-ray astronomers.

“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away,” Nelson said. “Safely landing and collecting the samples, launching a rocket with the samples off another planet — which has never been done before — and safely transporting the samples more than 33 million miles (53 million kilometers) back to Earth is no small task. We need to look outside the box to find a way ahead that is both affordable and returns samples in a reasonable time frame.”
—NASA: “NASA’s TESS Temporarily Pauses Science Observations“
NASA’s TESS (Transiting Exoplanet Survey Satellite) entered into safe mode April 8, temporarily interrupting science observations. The team is investigating the root cause of the safe mode, which occurred during scheduled engineering activities. The satellite itself remains in good health. The team will continue investigating the issue and is in the process of returning TESS to science observations in the coming days.
