Planet Labs PBC (formerly Planet Labs, Inc. and Cosmogia, Inc.) is a publicly held American Earth imaging company based in San Francisco, California.[1][4] Their goal is to image the entirety of the Earth daily to monitor changes and pinpoint trends.[5]

The company designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as secondary payloads on other rocket launch missions. Each Dove is equipped with a high-powered telescope and camera programmed to capture different swaths of Earth.[6] Each Dove Earth observation satellite continuously scans Earth, sending data once it passes over a ground station, by means of a frame image sensor.[7]

The images gathered by Doves, which can be accessed online and some of which is available under an open data access policy,[8] provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response.[1] With acquisition of BlackBridge in July 2015, Planet Labs had 87 Dove and 5 RapidEye satellites launched into orbit.[9] In 2017, Planet launched an additional 88 Dove satellites, and Google sold its subsidiary Terra Bella and its SkySat satellite constellation to Planet Labs.[10][11][12] By September 2018 the company had launched nearly 300 satellites, 150 of which are active.[13] In 2020, Planet Labs launched six additional high-resolution SkySats, SkySats 16–21, and 35 Dove satellites.[14]

Through a deal funded by Norway’s Climate and Forests Initiative (NICFI), Planet and its partners Airbus and KSAT are providing access to high-resolution basemaps of 64 tropical countries to help combat deforestation.[15] It also provides data to FAO's Framework for Ecosystem Monitoring (Ferm).[16]

Following a January 2021 launch of 48 Planet SuperDoves, the company operated a global constellation of over 200 active satellites.[17]

In July 2021 Planet Labs announced that they plan to become a public company and list on the New York Stock Exchange through a merger with the SPAC DMY Technology Group Inc IV. The deal would value Planet at US$2.8B.[18][19] The business combination was completed on December 7, 2021. Planet registered as a public benefit corporation and formally changed its name to Planet Labs PBC.[4] The stock began trading on the New York Stock Exchange on December 8, 2021. After the merger, Planet had more than $500 million in capital and about 190 satellites in orbit. The company expected it to take the next few years until they get to cashflow breakeven, funding their operations with $200 million from the aforementioned $500 million (the rest $300 million forming a "strategic warchest"). At the time of the merger, the company had over 600 customers (most customers, 90%, are annual subscriptions to Planet's data service) and it generated $113 million in revenue in 2020. At the time of the merger, Planet aimed to be profitable on an adjusted EBITDA basis by early 2025, and to grow its annual revenue to nearly $700 million by early 2026.[20]

Planet Labs has contracts to supply imagery to various agencies of the US government, including the FAS, NOAA, Oak Ridge, Sandia, the Bureau of Reclamation, and NASA.[21]

History

First pair of the 28 Planet Labs satellites launched from the ISS via the NanoRacks CubeSat Deployer (2014)

Planet Labs was founded in 2010 as Cosmogia by former NASA scientists Chris Boshuizen, Will Marshall, and Robbie Schingler, who teamed up with John Kuolt in 2011 during his studies at Oxford University with a thesis to leverage the processing power of mobile phones to power the avionics of a nano-satellite. Mr. Kuolt’s EP (Entrepreneurial Project) at Oxford University became the original business plan for Planet. [22][23][24] The initial goal of the company was to make use of information gathered from space to help with life on Earth. The group of scientists considered the problem with most satellites to be their large and clunky form, prompting them to build inexpensive and compact satellites to be manufactured in bulk, called CubeSats. The small group began building Planet's first satellite in a California garage.[25]

Planet Labs launched two demonstration CubeSats, Dove 1 and Dove 2, in April 2013.[26] Both Dove 1 (aboard Antares 110 rocket) and Dove 2 (aboard a Soyuz Rocket) were placed in a Sun-synchronous orbit.[27] Dove 3 and Dove 4 were launched in November 2013.[23]

In June 2013, it announced plans for Flock-1, a constellation of 28 Earth-observing satellites.[26]

The Flock-1 CubeSats were brought to the International Space Station in January 2014[28] and deployed via the NanoRacks CubeSat Deployer in mid-February.[29] The company planned to launch a total of 131 satellites by mid-2015.[30]

In January 2015, the firm raised $95 million in funding.[31] As of May 2015, Planet Labs raised a total amount of $183 million in venture capital financing.[32]

In July 2015, Planet Labs acquired BlackBridge and its RapidEye constellation.[33]

On April 18, 2017, Google completed the sale of Terra Bella and its SkySat satellite constellation to Planet Labs.[10][11][34] As part of the sale, Google acquired an equity stake in Planet and entered into a multi-year agreement to purchase SkySat imaging data.[35]

On January 21, 2018, a Dove Pioneer CubeSat was part of the payload of a Rocket Lab Electron rocket, the first orbital-entry craft launched from a privately owned and operated spaceport at Māhia Peninsula in New Zealand.[36]

In July 2018, Planet laid off somewhat less than ten percent of its workforce.[37] In September 2018, the company had launched a total of 298 satellites, 150 of which were still active.[13]

On December 18, 2018, Planet announced they were in the process of acquiring the St Louis company, Boundless Spatial, Inc., a geospatial data software solutions company.[38][39] The portfolio of Boundless will help improve data subscription services and aid in Planet's long-term goal of increasing cooperation between the company and the U.S. government.[38][39]

Several weeks after their acquisition of Boundless, Planet's attorney's asserted that executives from Boundless had failed to disclose “information concerning material customer contracts,” and the acquisition was thereafter renegotiated down by more than half, from $40M to $16M. According to Quartz, the executives of Boundless had failed to disclose details concerning work, or details concerning future work, with the NGA[40]

On 3 July 2020, it was mentioned in the news that the company had "more than 120" active satellites at the time "providing daily imaging coverage over all of the world’s landmass".[41]

In August 2020, Planet completed its SkySat Constellation of 21 satellites by launching the final three SkySats on a SpaceX Falcon 9 rocket.[42]

In May 2022, SES Government Solutions (now SES Space & Defense), a wholly-owned subsidiary of communications satellite owner and operator, SES, in partnership with Planet Labs, was awarded a US$28.96 million contract from NASA’s Communications Services Project for real-time, always-on low-latency connectivity services to NASA spacecraft in low-Earth orbit for routine missions, contingency operations, launch and ascent, and early operations phase communications, using SES's geostationary orbiting C-band satellites and medium Earth orbiting Ka-band satellites, including the forthcoming O3b mPOWER constellation.[43][44]

In August 2023, Planet cited "restructuring" as the reason for laying off 10% of its employees, about 120 individuals.[45] CEO William Marshall released a statement saying, "I want to be clear that I am responsible for the decisions that led us here. I know this has significant effects on the lives of our team and their families, and for that I am sorry."[46]

Flock satellite constellations

Planet Labs mission control

Planet's PlanetScope satellite constellation is designed to observe Earth. By using several small satellites, CubeSats, the constellation produces three to five meters high resolution images of Earth. The flock collects images from latitudes that are within 52 degrees of Earth's equator.[47] A large portion of the world's agricultural regions and population lie within the area imaged by the flock.[47] Initially, the mission used the ISS (International Space Station) and different track launch vehicles to get in orbit.[48]

Dove

Planet's Dove satellites are CubeSats that weigh 4 kilograms (8.8 lb) (1000 times lower than other commercial imaging satellites), 10 by 10 by 30 centimetres (3.9 in × 3.9 in × 11.8 in) in length, width and height,[49] orbit at a height of about 400 kilometres (250 mi) and provide imagery with a resolution of 3–5 metres (9.8–16.4 ft) and envisaged environmental, humanitarian, and business applications.[50][51]

RapidEye

RapidEye was a five-satellite constellation producing 5 metres (16 ft) resolution imagery that Planet acquired from the German company BlackBridge.

The satellites were built by Surrey Satellite Technology Ltd. (SSTL)[88] of Guildford, subcontracted by MacDonald Dettwiler (MDA) of Richmond, Canada. Each satellite was based on an evolution of the flight-proven SSTL-150[89] bus, measuring less than 1 cubic metre (35 cu ft) and weighing 150 kilograms (330 lb) (bus + payload) each. They were launched on 29 August 2008 on a Dnepr rocket from Baikonur cosmodrome in Kazakhstan.[90]

Each of RapidEye's five satellites contained identical Jena-Optronik Spaceborne Scanner JSS 56[91] multi-spectral pushbroom sensor imagers. The five satellites traveled on the same orbital plane (at an altitude of 630 km), and together were capable of collecting over 4 million kilometres (2.5×10^6 mi) of 5 metres (16 ft) resolution, 5-band color imagery every day. They collected data in the Blue (440–510 nm), Green (520–590 nm), Red (630–690 nm), Red-Edge (690–730 nm) and Near-Infrared (760–880 nm).

The RapidEye constellation was officially retired in April 2020.[92]

SkySat

SkySat is a constellation of sub-metre resolution Earth observation satellites that provide imagery, high-definition video and analytics services.[34] Planet acquired the satellites with their purchase of Terra Bella (formerly Skybox Imaging), a Mountain View, California-based company founded in 2009 by Dan Berkenstock, Julian Mann, John Fenwick, and Ching-Yu Hu,[93] from Google in 2017.[94]

The SkySat satellites are based on the CubeSat concept, using inexpensive automotive grade electronics and fast commercially available processors,[95] but scaled up to approximately the size of a minifridge.[96] The satellites are approximately 80 centimetres (31 in) long, compared to approximately 30 centimetres (12 in) for a 3U CubeSat, and weigh 100 kilograms (220 lb).[96]

The first SkySat satellite, SkySat-1, was launched on a Dnepr (rocket) from Yasny, Russia on 21 November 2013,[97] and the second, SkySat-2, launched on a Soyuz-2/Fregat rocket from Baikonur, Kazakhstan on 8 July 2014.[98] Four more SkySat units were launched on 16 September 2016, by the Vega rocket's seventh flight from Kourou,[99] and six more SkySat satellites, along with four Dove CubeSats, were launched on a Minotaur-C rocket from Vandenberg Air Force Base on 31 October 2017.[100][101]

In 2020, Planet lowered their constellation of 15 SkySats from an altitude of 500 kilometers to 450 kilometers to improve the resolution of orthorectified imagery from 80 centimeters to 50 centimeters per pixel.[102]

On June 13, 2020, SpaceX's Falcon 9 rocket successfully launched SkySats 16, 17 and 18 along with a batch of its Starlink communications satellites.[103]

SkySats 19, 20 and 21 were launched on August 18, 2020 on SpaceX's Falcon 9 rocket. This completed the SkySat fleet of 21 high-resolution satellites.[104]

When launched, the SkySat constellation was orbiting at an altitude of 450 kilometres (280 mi) and has a multispectral, panchromatic, and video sensor. It has a spatial resolution of 0.9 metres in its 400–900 nm panchromatic band, making it the smallest satellite to be put in orbit capable of such high resolution imagery. The multispectral sensor collects data in blue (450–515 nm), green (515–595 nm), red (605–695 nm), and near-infrared (740–900 nm) bands, all at 2 metre resolution.[105]

Pelican

The Pelican constellation is a constellation of Earth observation satellites to succeed the SkySat constellation.[106] The constellation is expected to consist of 32 spacecraft and will be based on a new design that includes Planet’s next generation of imaging sensors, capable of capturing images with a 30 cm resolution. The constellation will have a revisit rate up to 10 times per day for most of the globe, up to 30 times per day at mid-latitudes.[107] The first demonstrator satellite, Pelican-1, has been launched on 11 November 2023 on SpaceX Transporter-9 mission and wlll validate the satellite platform, that will be used also on the Tanager satellites, without providing any commercially available data.[108]
