Athena was a 1990s Lockheed Martin expendable launch system which underwent several name changes in its lifetime.
Development began at the Lockheed Corporation in 1993, where the design was known as the Lockheed Launch Vehicle. The name was subsequently changed to the Lockheed Martin Launch Vehicle when Lockheed merged with Martin Marietta. In 1997[3] the name was finally changed to Athena, and all of the launches after the demonstration flight in August 1995 were conducted using that name. Athena was retired from service in 2001, but in September 2010 Athena was added to NASA's Launch Services II contract. It was announced that it would be put back into production, with launches set to resume in 2012.[4] All production had ceased by March 2017.[5]
Variants
The Athena comes in two versions,
The Athena rocket uses an Orbit Adjust Module (OAM) developed by Primex Technologies. Primex was acquired by
Athena III
1990s proposal
An Athena III rocket was originally planned and designated the LLV-3 in the 1990s according to the original patent. It was never developed, because of the lack of customer interest. It was to add two, four or six Castor-4A strap-on boosters to the first stage of the stack, and would have been capable of launching 3.6 tons to low Earth orbit.[10]
PlanetSpace proposal
The designation was later reused for a proposed rocket for the
Athena III was to feature a 2 1⁄2-segment Space Shuttle Solid Rocket Booster (SRB) derived reusable solid rocket booster (RSRB) first stage topped by one Castor 120, one Castor 30 and an OAMS orbit adjust module. Athena III would have been capable of placing a 4,600 kg (10,100 lb) satellite in polar orbit from Kodiak, or launch a 5,900 kg (13,000 lb) satellite from the East Coast into an orbit due east; however an East Coast launch site had not been selected. Kodiak was selected over heavily booked Vandenberg to avoid delays in high-priority rapid-response launches for the U.S. military.[11]

Launch failures
Gemstar 1 (VitaSat 1) launch failure
On August 15, 1995, an Athena-1 rocket (vehicle DLV), failed during launch. Expended hydraulic fluid burned in first stage aft section, damaging nozzle feedback cables causing loss of gimbal control and tumbling. Separately, arcing in the IMU high-voltage power supply caused loss of attitude reference. Flight terminated by range safety officer at T+160 s.[13]
IKONOS-1 launch failure
On April 27, 1999, an Athena-2 rocket (vehicle LM-005), failed during launch. The payload fairing failed to separate, and the extra weight prevented the vehicle from reaching orbit. During the fairing separation event, the shock of the circumferential ordnance firing disconnected the cable carrying the signal to fire the longitudinal ordnance.[13]
