Ionospheric Connection Explorer (ICON) is a NASA mission to study Earth's thermosphere and ionosphere and the connection between space weather and weather on our planet. Mission is planned to last for two years.
The Pegasus is an air-launched rocket developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems). Capable of carrying small payloads of up to 443 kilograms (977 lb) into low Earth orbit, the vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 40,000 ft (12,000 m), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere.
A NASA space science spacecraft launched three years ago has been out of contact with controllers for nearly two weeks after suffering some kind of technical problem.
