Loft Orbital
Space is the ultimate high ground for collecting invaluable information about Earth. However today, satellite missions remain custom engineering projects that are technically complex, resource-intensive, and expensive.
Loft Orbital is changing that.
Our mission is to be the fastest, simplest, and most reliable path to orbit for any payload. We fly customer payloads onboard regularly scheduled satellites missions, and we handle the entire mission as a service. With Loft, our customers can focus on what matters most to them: their payload and the data it collects.
Under the hood, we've developed the software and hardware products that make our satellite missions truly plug and play, eliminating years of painful design and engineering. With qualified, commodity satellite buses procured in advance and available off-the-shelf, we deliver payloads to orbit in months not years.
