The first flight of a large aircraft to be powered by electric fuel cells began with a takeoff at 8:43 a.m. HST today from the Hawaiian island of Kauai. The Helios Prototype flying wing, built by AeroVironment, Inc., of Monrovia, Calif., as part of NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program, used solar panels to power its 10 electric motors for takeoff and during daylight portions of its planned 20-hour shakedown flight. As sunlight diminishes, Helios will switch to a fuel cell system to continue flight into the night. The takeoff set the stage for a two-day Helios endurance flight in the stratosphere planned for mid-July. The Helios wing, spanning 247 feet and weighing about 2,400 pounds, is giving NASA and industry engineers confidence that remotely piloted aircraft will be able to stay aloft for weeks at a time, providing environmental monitoring capabilities and telecommunications relay services. Helios is an all-electric airplane. In addition to being non-polluting, Helios can fly above storms, and use the power of the sun to stay aloft during daylight. Key to the success of this type of aircraft is the ability to fly in darkness, using fuel cells when sunlight cannot furnish energy. Helios flew over the Navy's Pacific Missile Range Facility where favorable sun exposure and test ranges closed to other air traffic benefited the NASA research effort. In 2003 the aircraft was lost to a crash.

The sun rises on the Space Shuttle Discovery as it rests on the runway at Edwards Air Force Base, California, after a safe landing August 9, 2005 to complete the STS-114 mission. Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT this morning, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle payload bay. Discovery launched on July 26 and spent almost 14 days on orbit.
