Operators deployed ~421 spacecraft with a mass of 200 kg or less, 18% of all deployed spacecraft in 2022. SpaceX’s Starlink satellites comprised over half the spacecraft mass deployed in 2022. The company’s Starlink deployments added up to 518,523 kg, nearly double the 257,140 kg it deployed in 2021. The largest spacecraft deployed during 2022 was Lockheed Martin’s Orion space capsule (25,848 kg), deployed during NASA’s first Artemis/Space Launch System launch.
Commercial space activity refers to efforts undertaken by private industry with little or no government investment. Commercial space revenue in 2021 totaled $362 billion.
Since Yuri Gagarin’s orbital flight around the Earth in April 1961, humans in pioneering new technologies and pushing the limits of what’s considered possible. This year ushered in a new era of human spaceflight when SpaceX became the first . . .
Satellite communications segment revenues for 2014 rose slightly to $## billion, ##% higher than the $## billion in revenue for 2013. Although broadcasts from satellites are a form of satellite communications, for the purposes of this report satellite communications are two-way transmission links between users and the satellites themselves. The links transmit data, voice, and video—although the distinction between…
Imagery and communications satellites were both used in search and rescue efforts for the Malaysian Airlines MH370 passenger airplane. Imagery of the search areas was provided on sites such as Tomnod in hopes that crowdsourcing imagery analysis would help in locating evidence of where the airplane might have disappeared.
There are other ways to become even more involved with space activities. Satellite imagery companies are offering opportunities for people to provide imagery analysis. Crowdsourcing has become a key approach and has resulted in websites such as DigitalGlobe’s Tomnod.[
Around the globe, many smaller nations—whether in terms of economy or population size—are investing in space projects or programs. The exhibit below shows the most recent available annual budget for civil space activities in a number of selected space states.
NASA’s Kennedy Space Center (KSC), the United States’ primary civil spaceport, marked its 50th anniversary in July 2012. The milestone coincides with the retirement of NASA’s Space Shuttle fleet and related changes in the U.S. human spaceflight program, causing uncertainty in the future utiliza… This article is for subscribers.

The DeforestACTION project is using satellite imagery to combat illegal logging through its Earth Watchers software tool, currently in beta testing. The difficulty of locating and identifying illegal deforestation often prevents law enforcement from limiting this activity. DeforestACTION allocates each person involved in the project a piece of land to monitor, providing them with an updated satellite image each week so they can locate changes and disturbances.
