Význam parametrů: Epocha - Datum (rok, měsíc, den a zlomek dne), pro něž platí uvedené parametry. Typ - Kód typu oběžné dráhy : G - geocentrická (Země), i - Sklon dráhy (úhel mezi rovinou dráhy a referenční rovinou, tj. rovníkem nebo ekliptikou). P - Perioda (doba oběhu). hP - Výška dráhy v pericentru. hA - Výška dráhy v apocentru.
Pasivní telekomunikační družice. Provozovatelem je NASA Headquarters, Office of Space Science and Applications (OSSA), Washington, DC (USA).
Balónová telekomunikační družice kulového tvaru o průměru 30.48 m. Je příhradové konstrukce s potahem tvořeným 82 segmenty mylarové fólie o síle 0.0127 mm. Vrchní povrch je z důvodu zlepšení odrazivosti opatřen vakuově nanesenou vrstvou hliníku a zaručuje 98% schopnost odrážet rádiové vlny o frekvencích do 20 GHz. V průběhu startu je družice složena v kulovém pouzdru o průměru 0.673 m. Po dosažení stanovené dráhy se pyrotechnicky oddělují dvě poloviny pouzdra a balón se nafoukne působením zbytkového vzduchu uvnitř a odpařením 15 kg sublimačního prášku (směs hyseliny benzoové a antrachinonu).
Pro snadnější sledování v počátečních fázích letu je družice doplněna dvojicí rádiomajáků s pracovní frekvencí 107.94 MHz umístěnou souměrně na povrchu balónu. Rádiové majáky jsou napájeny z 5 miniaturních NiCd baterií dobíjenými ze 70 slunečních článků. Vzhledem k velikému poměru průřez/hmotnost podléhá družice velkým změnám dráhy, čehož se využívá k výzkumu negravitačních vlivů na pohyb kosmického tělesa.
Předpokládaná aktivní životnost je asi 14 dní, z toho schopnost odrážet rádiové vlny asi 10 dní.
První úspěšně vypuštěná družice této řady. Předchozí družice stejného typu se 1960-05-13 pro havárii nosné rakety Thor Delta nedostala na oběžnou dráhu. Následující družicí této řady podobného typu je Echo 2 (1964-004A).

09:36:00 UT: Vzlet.
09:56:15 UT (T + 20 min 15 s): Oddělení pouzdra od nosné rakety. Během prvního oběhu se balón uvolnil z pouzdra a začal se plnit. |
1968-05-24 | Družice zanikla v zemské atmosféře. Plánovaná aktivní životnost byla značně překročena. |
