Hertz: cut reserves for TESS as part of belt-tightening. Schedules reserves are tight, but believe they’ll stay on track for March 18 launch

NASA trims reserves and shifts schedules to find astrophysics cost savings

Quote
“It required us to find $27 million in savings out of our total budget” from other astrophysics programs, Hertz said. Those cuts were incorporated into an operating plan for fiscal year 2017 approved in early September, less than a month before the end of the fiscal year.

The program affected the most is the Transiting Exoplanet Survey Satellite (TESS), a mission to search for exoplanets that is nearing completion for launch next year. A $15 million cut came from deferring a launch payment to fiscal year 2018 and effectively eliminating the remaining budget reserves held at NASA Headquarters.

“There are no further headquarters-held reserves in TESS funding that the project has received to launch in March of 2018,” Hertz said. The progress the mission was making, with the spacecraft currently undergoing a series of tests, made him confident the mission could stick to that schedule.

“Their schedule reserves are tight, but they have schedule reserves and they can make it,” he said. Should TESS run into problems, he said, NASA would have to find cuts in other astrophysics programs to make up the difference, or not launch TESS at all.

The @NASA_TESS successfully completed vibration testing @OrbitalATK! Vibration testing shakes the satellite to the real conditions that TESS will face during launch. It is vital to test the satellite to be sure it will survive the ride into orbit! https://t.co/5BQXwRexPa

@NASA_TESS Just conducting an MSPA (Mission Service Training activity) on #DSS24. This test validates ground systems using simulated TESS (Transiting Exoplanet Survey Satellite ) data. 125Mbit/s will be the DSN's fastest telemetry yet. Launch planned for next year.

Not fast.

Context is the keyword here. It is fast for DSN.

Seriously.  In what way is this not fast.  Galileo was 10bps, New Horizons maybe 1000bps.  125Mbps is astounding.  That's faster than my cable modem!

Historically, most space missions are X-band, and the total X-band bandwidth reserved for all near Earth missions combined is 50 MHz.  (See this Chart of Space Bands.)

So historically it is fast, and presumably is K band where the bandwidth is greater (as is Kepler, which was the previous record holder, I think...)

It's a Ka-transmitter from Space Micro

Rep. Mo Brooks (R-Ala.) quizzed Zurbuchen about the status of TESS’ launch vehicle, the SpaceX Falcon 9. The Block 4 version of the rocket that will be used to launch TESS has yet to be certified by NASA for the mission, and Brooks asked if there were concerns that the rocket will not be certified in time.

“At this moment in time I don’t have any such concerns,” Zurbuchen said, anticipating the certification process would be completed by early 2018.

Block 4 for sure on TESS it would seem, found at the end of this article about JWST.
