The $408 million Tracking and Data Relay satellite-M, was successfully lofted to a high-perigee geosynchronous transfer orbit by United Launch Alliance's Atlas 5 rocket from Cape Canaveral less than two weeks ago.

It then performed a series of orbit-raising maneuvers with its 100-pound thrust engine that boosted its highly elliptical orbit — roughly 2,888 statute miles at its closest approach to Earth to 22,230 statute miles at apogee with 26.1 degrees inclination — to a circular orbit.

The burns systematically raised the perigee to:
 – 6,568 miles at 17.6 degrees
 – 13,679 miles at 10.6 degrees
 – 19,918 miles at 7.7 degrees
 – 21,934 miles at 7.2 degrees
 – 22,204 miles at 7.1 degrees

After reaching a good orbit Monday, the craft spent Tuesday extending its power-generating solar panels that had been stowed against the satellite's main body for launch. TDRS-M now has a wingspan of 69 feet tip-to-tip.

Also, the booms holding the two 15-foot-diameter graphite composite mesh antennas were unfolded and the Space-to-Ground Link antenna was unlocked and re-positioned for use.

The current orbital slot is 150 degrees West longitude, over the Pacific, for checkout. Control of the satellite is being handed from Boeing's facilities in California to NASA's White Sands Complex in New Mexico for the start of on-orbit testing.

Commissioning will continue through January by Boeing engineers to demonstrate the spacecraft is functioning properly before NASA accepts ownership.
 
TDRS-M is the 12th and final Tracking and Data Relay satellite of the current era to be launched since 1983. Its addition to the existing 7-satellite constellation will ensure the system's viability into the mid-2020s at least.

TDRS provides constant communications between Earth-orbiting spacecraft and ground controllers, supporting round-the-clock operations of the International Space Station, plus data relay functions from the Hubble Space Telescope and nearly 40 scientific observatories.

NASA's TDRS-M Satellite Arrives in Geosynchronous Orbit, Completes Antenna & Array Deployment
August 30, 2017

NASA's TDRS-M satellite this week reached its high-altitude perch in Geosynchronous Orbit and completed all major deployment events on its solar arrays and antennas in preparation for a multi-month commissioning phase before entering an active role within the agency's Tracking and Data Relay Satellite System.

TDRS-M is the 13th TDRSS satellite to reach orbit and the third and final in the program's third generation that offers greater capacity than its predecessors to respond to growing communication demands, supporting 40+ NASA missions as well as other government satellites, commercial launch vehicles and airborne assets.

The 3,500-Kilogram satellite took flight at 12:29 UTC on Friday, August 18 atop an Atlas V 401 rocket blasting off fr om Cape Canaveral Air Force Station.

TDRS-M received a smooth ride atop the Atlas V workhorse that checked off its 72nd mission success – firing its RD-180-powered first stage for four minutes before the trusted Centaur upper stage took over for a customized two-burn mission design with a long 13.5-minute first burn into an initial orbit peaking 25,700 Kilometers in altitude followed by one and a half hours of passive flight to gain altitude ahead of a 56-second engine re-light to boost TDRS-M into its intended Geosynchronous Transfer Orbit.

Setting out on its mission, TDRS-M checked in with ground stations for a series of health checks that confirmed the Boeing-built satellite had arrived in orbit in excellent condition and was ready for its climb from an elliptical transfer orbit up to its operating post 35,800 Kilometers above the planet.

Tracking data provided by the Joint Space Operations Center showed the satellite in an initial orbit of 4,647 by 35,753 Kilometers at an inclination of 26.21°. Before starting its climb, the satellite freed up its two-large mesh antennas to take their parabolic shape while still remaining in the stowed configuration on the forward-facing side of the satellite.

Within three days of launch, TDRS-M had completed the first firing of its R-4D apogee engine, lifting the low point of the orbit to 10,560 Kilometers and shaving nine degrees off its orbital inclination.

The next apogee maneuver raised the orbit's low point to 22,000 Kilometers and decreased the inclination to 10.6 degrees and was followed by another firing that brought the perigee to 32,050 Kilometers and further reduced the inclination to 7.7 degrees. Another main engine firing placed the satellite in a 35,290 by 35,786-Kilometer orbit, inclined 7.11 degrees – leaving only some fine-tuning to be completed to reach a synchronous orbit in tune with Earth's rotation.

NASA announced on Monday that TDRS-M had achieved its planned GSO location and tracking data showed it in an orbit of 35,776 by 35,802 Kilometers, 7.0° at a position of 149.5 degrees west.

Having arrived in its planned checkout location, the 8.14-meter tall satellite began a complex deployment sequence. TDRS-M successfully deployed one of its 7.6-meter long solar arrays followed by the two 4.6-meter diameter single-access antennas each of which will be tasked with tracking a lower-orbiting spacecraft to provide a high-speed link in S/Ku/Ka-Band to relay vast amounts of data to the respective mission control centers. Afterwards, the satellite deployed its second solar array, the 1.9-meter Space-to-Ground Link Antenna and the omni-S-Band antenna that carries telemetry and commands for the TDRS satellite itself. All deployments went by the book, NASA reported, allowing TDRS-M to head into its four-to-five-month commissioning phase.

When commissioning is complete and the satellite is ready for service, it will be re-named TDRS-13 and drift into its initial operational location over the Atlantic coverage area to provide expansion capacity and TDRSS service extension through the 2020s to ensure the system can remain at full capacity through the International Space Station's planned lifetime.

TDRSS functions by deploying a series of communication relay satellites in three locations in Geostationary Orbit, over the Atlantic (TDRS-East), Pacific (TDRS-West) and TDRS-Z over the Indian Ocean, covering what is known as the Zone of Exclusion – a small blind area between the eastern and western satellites. Featuring different antennas, the satellites relay data from lower-orbiting spacecraft to ground terminals in Guam and New Mexico from wh ere data is routed to the respective users.

The most prominent user of TDRSS is the International Space Station, using high-rate communications to beam down a plethora of video and data feeds from dozens of scientific experiments on the inside and outside of the complex while low-rate communication links are used to provide a near-continuous voice link between Mission Control and the crew. TDRS also provides standard-of-living services for the crew like video-conferencing with their families, TV uplink and Internet access, using TDRS as a relay from the ground to a LEO spacecraft.

Beyond ISS, TDRSS supports other NASA flagship missions like the Hubble Space Telescope and the Landsat program that has kept watch over Planet Earth for over four decades. All in all, TDRSS is relied on by dozens of NASA missions and other users like the Department of Defence to keep in contact with some of its classified space assets.

TDRSS offers single-access services for data-intensive missions and a phased array on the satellite's Earth-facing side will provide multi-access links to several spacecraft at the same time. Each single-access antenna supports one spacecraft at a time, typically the ISS (when in view) and one other craft – used for high-data rate burst downlink of stored onboard data.

Single-access services are available in three bands – Ku/Ka-Band is employed for very high data rates up to 800 Mbit/s for the return link and S-Band rates can be as high as 25 Mbit/s. Multi-access allows each TDRSS satellite to receive and send data to up to five other satellites at the same time.

NASA has begun operating the last satellite of its kind in the network that provides communications and tracking services to more than 40 NASA missions, including critical, real-time communication with the International Space Station. Following its August launch and a five-month period of in-orbit testing, the third-generation Tracking and Data Relay Satellite (TDRS), referred to as TDRS-M until this important milestone, was renamed TDRS-13, becoming the tenth operational satellite in the geosynchronous, space-based fleet.

"With TDRS-13's successful acceptance into the network, the fleet is fully replenished and set to continue carrying out its important mission through the mid-2020s," said Badri Younes, NASA's deputy associate administrator for Space Communications and Navigation at NASA Headquarters in Washington. "Now, we have begun focusing on the next generation of near-Earth communications relay capabilities."

The 10 TDRS spacecraft comprise the space-based portion of the Space Network, relaying signals from low-Earth-orbiting missions with nearly 100 percent coverage.

"The acceptance of this final third-generation TDRS into the Space Network is the result of many years of dedication and hard work by the TDRS team," said Dave Littmann, the TDRS project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "As a result, critical space communication and tracking services that enable NASA human spaceflight and scientific discovery will continue well into the next decade."

​TDRS-13 launched on Aug. 18, 2017, aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida. Built by Boeing in El Segundo, California, TDRS-13 and its nearly identical third-generation sister spacecraft are performing well. TDRS-K and -L launched in 2013 and 2014, respectively.

NASA established the TDRS project in 1973, and the first satellite launched 10 years later, providing NASA an exponential increase in data rates and contact time communicating with the space shuttle and other orbiting spacecraft, such as the Hubble Space Telescope. Since then, NASA has continued to expand the TDRS constellation and advance the spacecraft capabilities.

"NASA looks forward to the future, developing even better ways to meet missions' communications needs," said Younes. "We will leverage NASA's success in optical communications and other innovative technologies, as well as significantly increase our partnership with industry, as we envision a shift to increased reliance on commercial networks for most, if not all, of our communications needs in the near-Earth environment."

Goddard is home to the TDRS project, which is responsible for the development and launch of these communication satellites. Boeing, headquartered in Chicago, Illinois, is the private contractor for the third-generation TDRS spacecraft. TDRS is the space element of NASA's Space Network, providing the critical communication and navigation lifeline for NASA missions. NASA's Space Communications and Navigation (SCaN) program, part of the Human Exploration and Operations Mission Directorate at the agency's Headquarters in Washington, is responsible for NASA's Space Network.
