The constellation of satellites charged with maintaining critical communications between NASA’s Space Network and Earth-orbiting spacecraft is about to be expanded by one.

Joining the Tracking and Data Relay Satellite (TDRS) System is TDRS-M, the third and final in a series of third-generation TDRS spacecraft that have taken their places in orbit in recent years. TDRS-M launched this morning aboard a United Launch Alliance (ULA) Atlas V rocket with a liftoff at 8:29 a.m. EDT from Cape Canaveral Air Force Station’s Space Launch Complex 41.

With light winds, few clouds and temperatures in the low 80s, weather posed no threat to launch. The countdown proceeded smoothly throughout the early morning hours and into propellant-loading operations, when engineers noted an issue with the Centaur upper stage’s liquid oxygen (LOX) chilldown system.

“As we were chilling the Centaur engine down, we noticed one of the chilldown parameters on the thermal conditioning for the LOX side was not quite getting cold enough” in time to permit liftoff at 8:03 a.m., when the 40-minute launch window opened, NASA Launch Manager Tim Dunn explained.

Just before sunrise at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, a United Launch Alliance Atlas V rocket vents liquid oxygen propellant vapors during fueling for the lift off of NASA's Tracking and Data Relay Satellite, TDRS-M. The team methodically worked to resolve the issue while maximizing that window of opportunity, and the issue was resolved in time for launch officials to set up for a successful liftoff at 8:29 a.m.

TDRS-M’s predecessors, TDRS-K and TDRS-L, also launched on Atlas V rockets from the same launch complex in January 2013 and January 2014, respectively. Today’s launch marked the 72nd liftoff of an Atlas V.

More than an hour and a half after launch, the TDRS-M spacecraft separated from the rocket’s Centaur upper stage, heralding the end of the launch effort and the mission’s beginning. Following several months of calibration and testing, TDRS-M will be renamed TDRS-13, and it will be eligible to begin supporting NASA’s Space Network.

“Spacecraft separation is the best part of the launch campaign,” Dunn said. “So many hours are put into getting to this exact point when you know you have a healthy satellite that just separated from the launch vehicle, about to go do its intended mission.”

NASA TV will broadcast two programs today from Kennedy Space Center in support of the launch of NASA’s next Tracking and Data Relay Satellite (TDRS) mission atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida. The programs will be carried live on NASA TV.

A prelaunch news conference will air live on NASA TV at 9 a.m. EDT Launch and mission managers will provide the current status of liftoff preparations and the launch weather forecast, as well as a look ahead at the satellite’s mission to come. This will be followed at 2 p.m. by a prelaunch Social Live briefing at 2 p.m. featuring some of the speakers, as well as NASA astronauts Steve Bowen and Nicole Mann, among other guests.

Launch coverage will begin at 7:30 a.m. on Friday with commentary leading up to the 8:03 a.m. start of a 40-minute launch window. Meteorologists with the U.S. Air Force 45th Weather Squadron are expecting good weather conditions tomorrow morning, with thick clouds the primary concern. The probability of favorable conditions has been upgraded to 80 percent.

A sign at NASA's Kennedy Space Center in Florida notes that a United Launch Alliance Atlas V rocket is scheduled to launch in two days. Liftoff of the Atlas V carrying Tracking and Data Relay Satellite-M (TDRS-M) is slated for Friday morning at 8:03 a.m. EDT from Space Launch Complex 41 at Florida's Cape Canaveral Air Force Station.

Only two days remain until the scheduled launch of NASA’s newest addition to the Tracking and Data Relay Satellite System. The TDRS-M satellite is in place atop a United Launch Alliance Atlas V rocket and final prelaunch milestones are being checked off in preparation for liftoff Friday morning at 8:03 a.m. EDT from Cape Canaveral Air Force Station’s Space Launch Complex 41.

The U.S. Air Force 45th Weather Squadron has issued today’s launch weather forecast. Meteorologists continue to predict a 70 percent chance of “go” weather at liftoff time, with thick clouds and cumulus clouds the primary concerns.

The Atlas V rocket is on the move this morning, making the short trek from the launch complex’s Vertical Integration Facility, where it was stacked and tested ahead of the flight, to the launch pad. The rollout is the final preflight move for the rocket and spacecraft, which will finish out the day in position for launch on Friday morning.

NASA’s Tracking and Data Relay Satellite-M (TDRS-M) has passed two more milestones as preparations continue toward liftoff. Launch of the newest addition to the agency’s TDRS constellation is slated for Aug. 18 at 8:03 a.m. EDT from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Processing activities at the Astrotech payload processing facility in nearby Titusville wrapped up with the TDRS-M spacecraft safely encapsulated in the payload fairing that will protect it through the early minutes of liftoff. The fairing arrived at the launch complex Aug. 9 after an early morning move from Astrotech. Now in position atop the United Launch Alliance Atlas V rocket, the vehicle and spacecraft will undergo additional testing ahead of launch.

TDRS-M Flight Ready, Aug. 18 Launch Date Approved

Posted on by .

The Omni S-band antenna on NASA’s Tracking and Data Relay Satellite (TDRS-M) has been successfully removed and replaced at Astrotech Space Operations in Titusville, Florida.  An unrelated electrostatic discharge incident has also been resolved, and launch processing has resumed.  The spacecraft has been moved from the fueling stand and is now mated to the launch vehicle adapter as part of integrated operations with ULA.

The TDRS-M spacecraft is flight ready, and the Eastern Range has recently approved Aug. 18 as the launch date.  NASA, Boeing, and United Launch Alliance (ULA) are targeting a 40-minute launch window that would open at 8:03 a.m. EDT. TDRS-M will launch on an ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida.

Delta IV Heavy Booster Cores Arrive for Parker Solar Probe

Framed by a series of cabbage palms, a United Launch Alliance Delta IV Heavy common booster core is transported by truck to Cape Canaveral Air Force Station's Launch Complex 37 Horizontal Processing Facility after arriving at Port Canaveral. The Delta IV Heavy will launch NASA's upcoming Parker Solar Probe mission. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection. Liftoff atop the Delta IV Heavy rocket is scheduled to take place from Cape Canaveral's Space Launch Complex 37 in summer 2018.

Launch preparations are beginning to get off the ground for NASA’s upcoming Parker Solar Probe mission, scheduled to lift off in summer 2018 atop a United Launch Alliance Delta IV Heavy rocket.

Two of the three common booster cores comprising the rocket’s first stage have arrived on the company’s Mariner ship, which delivered the components to Port Canaveral in Florida. From there the cores were offloaded and transported to the Horizontal Processing Facility at Cape Canaveral Air Force Station’s Space Launch Complex 37.

TDRS-M Status Update – July 26, 2017

Posted on by .

NASA has provided Boeing concurrence to remove and replace the Tracking and Data Relay Satellite’s (TDRS-M) Omni S-band forward antenna. Pending Eastern Range approval, NASA, Boeing, and United Launch Alliance (ULA) are now targeting Aug. 20 for launch. A 40-minute launch window would open at 7:56 a.m. EDT. This new date allows for time to replace the antenna, which was damaged earlier this month while Boeing was conducting final spacecraft closeout activities at Astrotech Space Operations in Titusville, Florida. TDRS-M will launch atop an ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida.

TDRS-M Status Update – July 21, 2017

Posted on by .

NASA, Boeing and United Launch Alliance (ULA) are reviewing a new launch date in August for the agency’s Tracking and Data Relay Satellite (TDRS-M). NASA and Boeing need additional time to replace the spacecraft’s Omni S-band antenna at Astrotech Space Operations in Titusville, Florida. A separate possible ground support equipment issue at Astrotech still is being assessed. TDRS-M will launch on a ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida. It is the latest satellite in a fleet of satellites supporting the space segment of the NASA’s Space Network.
