Experimental Schedule

This was the schedule for the SVT, PVT, and flight for BRIC-17 TOAST which flew to the ISS in March of 2013 on SpaceX CRS-2. The same schedule will be used for our BRIC-19 TOAST II & GeneLAB experiments, which will fly on SpaceX CRS-4 (SpX-4) mission. The launch for SpX-4 is planned for September 19, 2014; berthing of the Dragon capsule to the ISS will happen 2 days later on September 21, 2014.

  • Day -4 – Planting of seeds onto phytagel in our lab in the SSPF.
  • Day -3 – Manifold and valve assembly for the PDFU.
  • Day -2 – Integration: “Build-up” of flight PDFU including science, PDFU leak testing, and canister assembly.
  • Day 0 – Launch.
  • Day 2 through 8Growth of seedlings in microgravity on the ISS.
  • Day 8 – Actuation of the flight BRIC canisters (fixation liquid) by an astronaut.
  • Day 9 – Freeze canisters.
  • Day xx – Dragon capsule landing.
  • Day xx – De-integration, sample processing and shipment to University of Wisconsin – Madison.

Here’s a look at the timeline of the Gilroy Lab’s NASA funded BRIC-17 Test Of Arabidopsis Space Transcriptome (TOAST) project, the first BRIC experiment our lab sent to the ISS in 2013.


The Big Picture

  • September 2011 – NASA research announcement request for proposals (RFP).
  • January 2012 – Deadline for submission of proposal to NASA.
  • April 2012 – Notification of funding from NASA for BRIC-17.
  • June 2012 – NASA grant begins.
  • July 2012 – First Gilroy Lab team visit to the Space Life Science (SLS) lab at KSC in Florida for start of the TOAST Science Verification Test (SVT).
  • August 2012 – Return to SLS lab (Sarah only) to process and ship SVT plants to UW-Madison.
  • September 2012 – Analyse the BRIC-17 SVT results at UW-Madison.
  • October 2012 – Second Gilroy Lab team visit to KSC’s SLS lab for start of the Payload Verification Test (PVT); Return to SLS lab to process and ship PVT plants to our lab at UW-Madison.
  • November 2012 – Analyse the BRIC-17 TOAST PVT results at UW-Madison.
  • March 2013 – Third Gilroy Lab team visit to KSC’s SLS lab for launch of SpaceX-2; BRIC-17 runs on the ISS in parallel with ground controls.
  • April 2013 – Return of the BRIC-17 TOAST experiment from the ISS back to Earth; Gilroy Lab team visits the SLS lab to process and ship space-flown and Earth-grown control plants to UW-Madison.
  • May 2013 to 2014 – Analyse the space-flown and Earth-grown BRIC-17 TOAST seedlings.
