Wczoraj TESS wykonał pierwszy manewr z uruchomieniem silników w apogeum (A1M).

The @NASA_TESS first apogee maneuver (A1M) was successfully completed yesterday. This burn was a 50 second checkout burn to characterize the performance of the #TESS thrusters.

.@NASA_TESS current speed (at about 22 Apr 2018 15:46 UTC / 11:46 AM EST) was approximately 0.373 km/s. It will be increasing until #TESS reaches perigee at about 25 Apr 2018 05:42 UTC / 1:42 PM at which point it will be approximately 9.51 km/s.

Jeszcze zdjęcie z portu z barką, I stopniem i robotem. Widać precyzję lądowania, niemal dokładnie w sam środek.

Same pozytywne wieści.

Wyładunek pierwszego stopnia w porcie i (na początku filmu) odzyskana owiewka.

Udało im się też odzyskać drugą owiewkę, ale mocno uszkodzoną. Prawdopodobnie nie miała spadochronu tylko sam system RCS.

Tymczasem TESS wykonał drugi manewr z uruchomieniem silników (P1M) oraz przeprowadzono pomyslne testy systemów komunikacji:

.@NASA_TESS successfully completed the first perigee maneuver (PM1). Initial indications are that the burn was nominal. P1M is the second of six on orbit burns for #TESS to reach its final science orbit.

.@NASA_TESS Mission Update: The Ka-band transmitter and Traveling Wave Tube Amplifier were turned on. @NASASCaN's Deep Space Network successfully locked on to the Ka signal immediately. The link showed a strong link margin with no errors.

.@NASA_TESS Mission Update: The #TESS ADHU (data handling unit computer for the instrument from @SEAKR_Eng) was turned on. Checkout confirmed all nominal. #TESS sent data from the ADHU to the Ka Transmitter and received packets at DSN without errors.

Mała aktualizacja. W ciągu ostatnich kilku dni kontynuowano sprawdzanie instrumentów i ich kalibrację. Ze względu na dobre parametry zrezygnowano z drugiego uruchomienia silników w apogeum (A2M), natomiast drugie uruchomienie w perygeum (P2M) poszło zgodnie z planem.

.@NASA_TESS Mission Update: Team decided that the second apogee maneuver (Apogee 2 maneuver (A2M)), was not necessary based on the good system performance during the first two maneuvers. Spacecraft subsystems continue to operate nominally.

.@NASA_TESS Mission Update: The four cameras for #TESS are now powered on and will begin collecting data for the calibration process which will last until mid June.

.@NASA_TESS Mission Update: The #TESS team were successful in putting TESS in Fine Pointing Mode (instrument supplying quaternions) for the first time as part of instrument commissioning.

.@NASA_TESS Mission Update: #TESS continued fine pointing data collection for instrument calibration. The #TESS cameras are being slowly cooled to their operating temperature of -80°C.

.@NASA_TESS Mission Update: completed the P2M (Perigee 2 Maneuver), another on orbit burn to place #TESS into its final science orbit, nominally. The instrument is turned off for all maneuvers. While this maneuver is only for 7 secs it puts TESS on target for our lunar encounter.
