Impulse Space said it would offer rideshare missions to GEO using its high-energy Helios orbital transfer vehicle<\/a> under development. The company said it was prompted to offer the service by the number of \u201cmicroGEO\u201d spacecraft under development with masses of one ton or less.<\/p>\n\u201cWe\u2019re going to gauge the demand and see if it\u2019s real,\u201d Tom Mueller, founder and chief executive of Impulse Space, said at the time.<\/p>\n
A year later, Impulse has concluded the demand is real. \u201cTwelve months ago, we got up here and we were saying that we think there is a market for GEO rideshare,\u201d said Joshua Rea, director of commercial sales at Impulse, during an Aug. 12 presentation at the Small Satellite Conference here. \u201cTwelve months on, there\u2019s a real market need.\u201d<\/p>\n
That GEO rideshare service, which Impulse Space recently named Caravan, will involve an annual series of dedicated Falcon 9 launches of Helios, currently planned for the third quarter of each year. The first mission, Caravan 1, is scheduled for the third quarter of 2026 and is fully booked. Caravan 2 will follow in 2027 and Caravan 3 in 2028.<\/p>\n
The missions will use the Helios vehicle to rapidly transfer from an initial low Earth orbit to GEO. One burn shortly after payload deployment puts Helios into a geostationary transfer orbit, while a second about six hours later circularizes the orbit just above GEO. Payload deployment takes place eight hours after launch.<\/p>\n
The payloads will be dropped off about 500 kilometers above GEO, allowing payloads to drift at a rate of about five degrees per day to reach their desired orbital slot and then lower themselves into GEO. After deployment, Impulse will then move Helios into a higher graveyard orbit and passivate it.<\/p>\n
That process, Rea said, is intended to address any space safety issues about GEO satellite deployments. \u201cIt\u2019s important for us to be a responsible operator.\u201d<\/p>\n
The Caravan program is modeled on SpaceX\u2019s popular rideshare missions for satellites going to LEO, including form factors and attachment ports. \u201cEssentially, if you are designing your spacecraft for the SpaceX rideshare program today, it is more than likely that you are going to be compatible with ours,\u201d he said.<\/p>\n
A standard dispenser plate is available, with 300 kilograms of payload included and the ability to go to payloads as heavy as 700 kilograms. A larger heavy dispenser plate includes 700 kilograms of payload and can support payloads weighing up to 1,400 kilograms. The heavy plates, Rea said, should be able to accommodate most microGEO spacecraft.<\/p>\n
Each Caravan mission will be able to carry up to four tons of payloads. The company expects to take between 18 and 24 months from contract signing with a rideshare customer to launch of that customer\u2019s payload.<\/p>\n
Rea said that Impulse offers \u201cvery clear and transparent\u201d pricing for Caravan missions based on payload mass, but didn\u2019t disclose specific prices. \u201cI think you will be hard-pressed to find any other price that\u2019s competitive with this for direct to GEO.\u201d<\/p>\n
