It took the rover about an hour to take all the images necessary to compile into a single selfie. Breakthroughs, discoveries, and DIY tips sent six days a week. After five years of rolling across Mars, NASA's Perseverance rover is still going strong.

This is the first time NASA has encountered a situation like this, and it took nearly a week to resolve. The Curiosity rover landed on Mars in August 2012. While it has enabled many exciting discoveries, the Curiosity Rover has also encountered its share of setbacks. The latest left NASA engineers speechless. On April 25, Curiosity drilled into a rock nicknamed "Atacama" to collect a sample.

The multi-day challenge took multiple attempts to fix. Breakthroughs, discoveries, and DIY tips sent six days a week. Curiosity got itself stuck between a rock and hard place last month, but NASA says there's no reason to fret about the intrepid Mars rover . On April 25, mission engineers were remotely piloting its robotic arm's rotary-percussive drill into a Martian rock nicknamed Atacama.

Vision-language models (VLMs) have exhibited impressive capabilities across diverse image understanding tasks, but still struggle in settings that require reasoning over extended sequences of camera frames from a video. This limits their utility in embodied settings, which require reasoning over long frame sequences from a continuous stream of visual input at each moment of a task attempt. To address this limitation, we propose ROVER (Reasoning Over VidEo Recursively), a framework that enables the model to recursively decompose long-horizon video trajectories into segments corresponding to shorter subtasks within the trajectory. In doing so, ROVER facilitates more focused and accurate reasoning over temporally localized frame sequences without losing global context. We evaluate ROVER, implemented using an in-context learning approach, on diverse OpenX Embodiment videos and on a new dataset derived from RoboCasa that consists of 543 videos showing both expert and perturbed non-expert trajectories across 27 robotic manipulation tasks. ROVER outperforms strong baselines across three video reasoning tasks: task progress estimation, frame-level natural language reasoning, and video question answering. We observe that, by reducing the number of frames the model reasons over at each timestep, ROVER mitigates hallucinations, especially during unexpected or non-optimal moments of a trajectory. In addition, by enabling the implementation of a subtask-specific sliding context window, ROVER's time complexity scales linearly with video length, an asymptotic improvement over baselines.

NASA's Perseverance rover discovers a shiny metallic rock nicknamed 'Phippsaksla' on Mars that scientists believe could be a meteorite from an ancient asteroid.

They're rare events, but the results are dramatic. Breakthroughs, discoveries, and DIY tips sent every weekday. Mars receives its fair share of cosmic collisions . With less than one percent the atmosphere as Earth, some meteoroids fail to burn up entirely before reaching the Red Planet's surface. When they do, they can usher dramatic changes to the barren Martian landscape that stretch for miles.
