Delta 4 launch seen from press viewing site (members only)

Headed to a relic from the solar system’s formation over four billion years ago, NASA’s OSIRIS-REx sample return craft was moved to Cape Canaveral’s Complex 41 launch pad today in preparation for liftoff Thursday aboard an Atlas 5 rocket en route to Asteroid Bennu hoping to find the seeds of life.

A European-built Ariane 5 rocket launched Tuesday with a U.S.-made communications satellite for Tokyo-based Sky Perfect JSAT and a South Korean environmental observatory. The heavy-lift Ariane 5 launcher took off from the Guiana Space Center in Kourou, French Guiana, at 5:18 p.m. EST (2218 GMT; 7:18 p.m. French Guiana time).

A Vega rocket faltered minutes after liftoff from French Guiana at 9:53 p.m. EDT Wednesday (0153 GMT) and failed to reach orbit with a European-built reconnaissance satellite for the United Arab Emirates. The payload and launcher fell into the Atlantic Ocean, marking the first failure for the solid-fueled Vega launch vehicle.
