Time-lapse: Watch the Crew Dragon and Falcon 9 roll to the launch pad (members only)

The most-used instrument on the orbiting Hubble Space Telescope is back in business after engineers on the ground determined a fault that halted the camera’s science observations earlier this month was caused by erroneous telemetry data, and was not a symptom of a hardware failure as initially suspected.

SpaceX chief Elon Musk said last week he is “fairly confident” his company’s Falcon rockets can be made fully reusable within a couple of years, suggesting a renewed emphasis on outfitting upper stages for a scorching re-entry after engineers shelved the idea to focus on landing the launcher’s bigger booster stage.
