印度太空科技初创公司Pixxel成功发射了其商业星座Firefly的首批三颗高光谱卫星,这标志着印度太空雄心迈出了重要一步。这些卫星将提供高分辨率的高光谱图像,用于监测环境变化、农业状况等。Pixxel计划在未来几年内发射更多卫星,以实现每日全球覆盖。此次发射不仅是Pixxel商业运营的开始,也突显了印度在太空领域的快速发展,包括月球探测、日冕观测以及与NASA的合作。

🚀Pixxel成功发射了首批三颗高光谱商业卫星,标志着印度首个私人商业星座的开始。这些卫星具备五米分辨率,覆盖40公里宽的区域,能够捕捉超过150个光谱波段的数据,用于检测化学成分、植被健康、水质和大气条件。

🛰️这些高光谱卫星配备了窄带传感器,能够发现隐藏的模式和异常,对于农业和气候应用非常有价值。与无人机相比,卫星在监测大范围区域时更有效率,例如森林砍伐、海洋污染、石油泄漏和水质问题。

🌍Pixxel的目标是在2026-2027年拥有18到24颗卫星,实现全球每日覆盖。目前,其卫星的商业运营将提供每两到三天的全球数据。这些卫星还配备了推进系统,使其在轨道上保持长达七年的寿命,远超演示卫星的一年半到两年。

Pixxel, an Indian space tech startup, has successfully launched the first three hyperspectral satellites of its commercial constellation Firefly aboard a SpaceX rocket from California, marking a significant milestone for the India’s growing space ambitions.

India is home to around 300 space startups and has gained worldwide attention for recent developments, including the successful landing of its lunar spacecraft on the south pole, the launch of a coronagraphy spacecraft, and partnering with NASA to join the Artemis Accords. Further, India plans to launch its first human spacecraft mission next year, own a space station by 2035, and send an astronaut on a three-day moon mission by 2040.

The latest launch is the start of commercial operations for Bengaluru-based Pixxel, and took place from the Vandenberg Space Force Base Tuesday at around 10:45 a.m. PT under SpaceX’s Transporter-12 rideshare mission. Hyperspectral satellites have gained popularity among space companies as large corporations and governments seek insights into deforestation, ocean pollution, oil spills, and water quality. While drones can provide some data, satellites are generally more effective and efficient in most of these cases.

The three satellites are a part of the five-year-old startup’s first commercialization phase, which will include three more by Q2, and a total of 18 to 24 satellites by 2026–2027, its chief said in an interview hours before the launch.

“It is the world’s highest-resolution hyperspectral satellite constellation and India’s first-ever private commercial constellation,” Pixxel co-founder and CEO Awais Ahmed told TechCrunch.

Pixxel built the Firefly satellites to provide hyperspectral imagery at a five-meter resolution, covering a 40-kilometer (~25-mile) wide swath. The satellites can capture data across over 150 spectral bands to detect subtle changes in chemical compositions, vegetation health, water quality, and atmospheric conditions. Onboard narrowband sensors help find hidden patterns and anomalies, which can be helpful for agricultural and climate applications.

The startup has signed over 60 customers in the last few years, including the Indian agriculture ministry, British Petroleum, and NASA. Some are already getting hyperspectral imagery data through demo satellites launched in 2021 and 2022, but the six satellites the startup aims to launch this year will bring “a lot more data than the demo satellites,” Ahmed said.

“It’s like when you’re hearing a musical note, you understand what keys it’s made up of, and those keys are what we are trying to pick with hyperspectral data,” Pixxel co-founder and CTO Kshitij Khandelwal told TechCrunch.

The satellites will circumnavigate in a sun-synchronous orbit at around 342 miles. While the first three satellites will help Pixxel begin its commercial operations, they will not provide daily global coverage, providing insights every two to three days instead. Pixxel executives said they need to add three additional satellites for daily coverage.

The commercial satellites also include native propulsion systems to help them stay in precise orbit for up to seven years, versus a one-and-a-half to two-year lifetime on the demo satellites.

Startups such as Esper, Orbital Sidekick, and Wyvern are trying to attract customers in this domain. But Ahmed told TechCrunch that Pixxel is so far the only player offering truly five-meter hyperspectral satellites.

“Some of them are doing multispectral… but still in like eight wavelengths or so. With hyperspectral, we’re able to do 150 wavelengths at five meters, and that is what sets us apart from existing players,” he said.

On why Pixxel preferred a SpaceX rocket instead of an Indian Space Research Organization (ISRO) one, Ahmed said it was just the timing of the launch and orbital parameters.

Pixxel, which has so far raised $95 million in funding, counts Accenture Ventures, Google, Lightspeed Venture Partners, and Radical Ventures among its key investors.

Ahmed told TechCrunch that beyond Google’s investment, Pixxel is exploring how it can integrate its hyperspectral satellite insights with Google Earth and other Google products and services.

Last year, India announced a $116 million venture capital fund for space developments. The country also introduced a dedicated space policy and updated its foreign direct investment policy for overseas space-related investments to continue expanding its global space industry footprint.
