The National Reconnaissance Office ultimate revealed the existence of its “JUMPSEAT” line of spy satellites, eight of which launched to Earth orbit between 1971 and 1987.

We ultimate discovered about a pioneering U.S. spy satellite program, almost 40 years after its final spacecraft launched to the last frontier.
On Wednesday (Jan. 28), the U.S.
“The historical significance of JUMPSEAT cannot be [over]stated,” James Outzen, NRO director of the Center for the Ogle of National Reconnaissance, said in a

Because the timeframe implies, signals intelligence involves the detection and decryption of electromagnetic signals — adversary communications, as an instance, or emissions from missiles or various weapons programs.
Early within the house age, the US launched some digital surveillance satellites to
The company, which was essentially based in 1961, worked with the U.S. Air Power in direction of this end on a program that came to be identified as “Project EARPOP.” The final consequence was JUMPSEAT, a satellite designed to characteristic in a form of HEO known as a Molniya orbit.
Molniya orbits are inclined 63 degrees relative to the equator and characteristic a perigee (closest

These characteristics enable satellites in Molniya orbits to linger over high-latitude stretches of the Northern Hemisphere for prolonged periods. Now not coincidentally, this fits the geography of the Soviet Union, the US’ Chilly Battle rival.
“JUMPSEAT’s core mission focus was to monitor adversarial offensive and defensive weapon system development,” NRO officials wrote within the same reveal. “From its further orbital position, it aimed to collect data that might offer unique insight into existing and emerging threats.”
The considerable JUMPSEAT satellite launched in 1971 from California’s Vandenberg Air Power Imperfect, which is now identified as
“Once in orbit, JUMPSEAT successfully collected electronic emissions and signals, communication intelligence and foreign instrumentation intelligence — invaluable information that was downlinked to ground processing facilities within the U.S.,” company officials wrote.
Seven various JUMPSEAT spacecraft reached orbit over the next decade and a half of, concluding with JUMPSEAT 8 in
Many hundreds of U.S. spy satellites own adopted JUMPSEAT to house; the NRO is often upgrading its rapid of reconnaissance spacecraft. For instance, the company is currently constructing out its recent “

He essentially covers exoplanets, spaceflight and military house, but has been identified to dabble within the house art work beat. His e book about the build a matter to for alien existence, “Out There,” was published on Nov. 13, 2018. Before turning exact into a science author, Michael worked as a herpetologist and wildlife biologist. He has a Ph.D. in evolutionary biology from the College of Sydney, Australia, a bachelor’s degree from the College of Arizona, and a graduate certificate in science writing from the College of California, Santa Cruz.
