Live coverage: NASA confirms successful first flight of Mars helicopter

Within days, NASA is expected to select a winner from a roster of nine eligible companies to try and become the first commercial entity to accomplish a soft landing on the moon with a robotic spacecraft. The privately-developed probe would be the vanguard in a series of unpiloted missions intended to deliver science instruments to the lunar surface and prepare for a human expedition as soon as 2024.

NASA is examining options to launch a robotic mission as soon as 2026 to pick up rock specimens from the surface of Mars and bring them back to Earth, moving forward the timeline for a sample return mission as the agency postpones plans for a new Mars reconnaissance and data relay orbiter.

The commercial Cygnus freighter carrying over 7,000 pounds of food, supplies and science experiments completed a flawless rendezvous with the International Space Station on Saturday morning. It was captured by the robotic arm at 6:51 a.m. EDT (1051 GMT).
