The launch of the Joint Polar Satellite System-1 (JPSS-1) satellite, the first in a new series of four highly advanced National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites, now is scheduled for Saturday, Nov. 18, from Vandenberg Air Force Base, California.

Liftoff aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 is targeted for 4:47 a.m. EST (1:47 a.m. PST).



NASA TV launch coverage begins at 4:15 a.m. and will conclude after the deployment of four small satellite missions, called CubeSats, which will accompany JPSS-1 as payload on the Delta II rocket. There is no planned post-launch news conference. A post-launch news release will be issued as soon as the state-of-health of the spacecraft is verified.

JPSS represents significant technological and scientific advancements in observations used for severe weather prediction and environmental monitoring. JPSS is a collaborative effort between NOAA and NASA. The JPSS system will help increase weather forecast accuracy from three to seven days.

Audio only of the news conferences and launch coverage will be carried on the NASA V circuits, which may be accessed by dialing 321-867-1220, -1240, -1260 or -7135. On launch day, mission audio, the launch conductor's countdown activities without NASA TV launch commentary, will be carried on 321-867-7135.

Additional launch day coverage will be available on NASA.gov. Coverage will include live streaming and blog updates beginning at 4:15 a.m. as countdown milestones occur. You can follow countdown coverage on our launch blog at https://blogs.nasa.gov/jpss.

Look Ahead: Countdown, Ascent Miles | Reaction of: DRRA-KJvTil on 18-11-17 11:10 | E-mail: info(at)drra.nl
There will be one more built-in hold at T-4 minutes, and launch management will take that opportunity to verify the Delta II rocket, JPSS-1 spacecraft and all other necessary assets are ready for launch. The countdown will resume at 1:43 a.m. At 1:47 a.m., the Delta II rocket’s main engine and six of its nine solid rocket motors will ignite, and JPSS-1 will be on its way into polar orbit.



Watch for a chain of events starting at about 4 minutes, 20 seconds after liftoff: the main engine will cut off (MECO), the first and second stages will separate, the rocket’s second-stage engine will start its first burn, then the payload fairing will separate and fall away. The entire sequence takes less than 20 seconds.

The second-stage engine cuts off (SECO 1) about 10-and-a-half minutes into the flight, starting a coast phase lasting approximately 40 minutes. At the end of the coast phase, the engine ignites again for a short burn — less than half a minute — with JPSS-1 spacecraft separation expected 57 minutes after liftoff. An additional quick engine burn then will be followed by deployment of the CubeSats.

MECO Complete, Second-Stage Burn in Progress

Main engine cutoff occurred on time, the first and second stages separated as planned and the second-stage engine has started its first burn. The payload fairing that protected the JPSS-1 satellite during the first minutes of ascent has jettisoned as expected.

SECO 1: Coast Phase Begins

The Delta II rocket’s second-stage engine has cut off, finishing its first burn. This marks the beginning of of coast phase lasting just over 40 minutes. The engine will reignite for its second burn at 2:38 a.m. PST (5:38 a.m. EST).

SECO 2: Second Burn Complete

The Delta II rocket’s second-stage engine has finished its second burn. Stand by for JPSS-1 spacecraft separation about six minutes from now.

JPSS-1 Spacecraft Separation! | Reaction of: DRRA-KJvTil on 18-11-17 11:55 | E-mail: info(at)drra.nl
Flying 440 nautical miles over the Indian Ocean, NOAA's Joint Polar Satellite System-1 spacecraft has separated from the second stage of the United Launch Alliance Delta II rocket that delivered it to orbit this morning.

The next major milestone will be the third burn of the Delta II second stage – a quick burn lasting about 18 seconds – to prepare for deployment of the P-PODs, releasing the five CubeSats.

Dit was de op een na laatste Delta 2 die onlangs gelanceerd werd. Volgend jaar semptember is de laatste vlucht gepland.
