SpaceX is getting ready to launch its thirty first resupply mission to the Worldwide Area Station on Monday night time, climate allowing.
The mission, dubbed Business Resupply Providers-31 (CRS-31) will ferry greater than 6,000 kilos of cargo and science experiments to the orbiting outpost. Liftoff of the Falcon 9 rocket from Launch Advanced 39A (LC-39A) is about for 9:29 p.m. EST (0229 UTC).
Spaceflight Now could have reside protection starting about an hour and a half previous to liftoff.
The Cargo Dragon spacecraft, C208, will make its fifth journey to the ISS. It beforehand flew on CRS-21, 23, 25 and 28. It would take about 13 hours after liftoff to succeed in the area station.
It’s getting an preliminary enhance from the Falcon 9 first stage booster, B1083. It too is making its fifth flight after beforehand launching Crew-8 for NASA, Polaris Daybreak for the Polaris Program and two Starlink missions (Group 6-48 and Group 6-56).
Almost eight minutes after liftoff, B1083 will return to Florida for a landing at Touchdown Zone 1 (LZ-1) at Cape Canaveral Area Drive Station. If profitable, it should mark the forty sixth booster touchdown at LZ-1 and the 362nd booster touchdown thus far.
The mission comes a day after SpaceX scrubbed a deliberate Starlink launch on Sunday as a result of a primary stage helium problem, the fuel used to pressurize the principle propellant tanks in addition to enable for stage separation.
NASA, SpaceX and the ISS worldwide companions will probably focus on the matter throughout a launch readiness assessment scheduled for Monday. The CRS-31 mission was already operating delayed, since they initially deliberate to lift the rocket at LC-39A on Saturday, however didn’t convey it upright till round 7 p.m. EST (0000 UTC).
Welding provides, moss and photo voltaic wind screens
In response to NASA, the SpaceX Cargo Dragon spacecraft has 5,368 kilos (2435 kg) of pressurized cargo together with a 721 pound (327 kg) payload in its trunk.
The overwhelming majority of what’s heading as much as the orbiting outpost is numerous parts for science experiments and know-how demonstrations for NASA, college researchers, personal firms and dozens of scholar teams.
Nestled contained in the trunk of the Dragon is a tool known as CODEX (COronal Diagnostic EXperiment), which is a photo voltaic coronagraph designed to review the formation and impacts of photo voltaic wind. Jeffrey Newmark, a analysis astrophysicist at NASA’s Goddard Spaceflight Middle stated the machine might be unpacked and put in utilizing the Canadarm-2 robotic arm.
“We’ve developed on the bottom three key applied sciences that we’re testing now in area. First is our precise coronagraph design. Coronagraph is the instrument that blocks the Solar. There have been earlier coronagraphs which have flown in area, however we’ve got a brand new design to actually decrease the stray mild and actually optimize the faint options that we’re searching for,” Newmark stated. “Subsequent, we’ve developed a polarization digicam, a specialised digicam that may take a look at the sunshine and separate the polarized half, the sunshine that’s centered at us, in several instructions. And this replaces earlier missions which have had a really, very complicated mechanism. So, this can be a actually simpler, cheaper and higher technique to do it.
“Lastly, the actual breakthrough for this mission… this would be the first time that we’ve measured all three of those key properties: the density, the temperature and pace of the photo voltaic wind on the identical time. And we’re doing this globally.”
The CODEX experiment is designed to function for at the very least six months as soon as it’s put in onto the zenith (space-facing) facet of the Categorical Logistics Service 3 on the ISS. Newmark stated they can even be opening the info to the general public and placing it on a group web site for large use.
Supplies for a so-called “chilly welding” experiment known as Nanolab Astrobeat are additionally onboard the Dragon on behalf of Voyager Area and its analysis companion, Malta Faculty of Arts, Sciences & Know-how. The experiment is designed to additional the choices for repairing the hulls of spacecraft following the impacts of micrometeoroids.
“The take a look at rig is ready to simulate the hull breach when it comes to crack and opening and is able to making use of the restore patch and monitoring its efficiency. The 2-patch software programs are examined in orbit. One is aluminum, and the opposite is copper,” NASA wrote. “Upon activation, one of many 4 chambers of the payload releases the strain within the spring and collides two items of metallic collectively (both aluminum or copper) to carry out chilly welding. A digicam captures the activation of the chamber for affirmation.”
The Astrobeat pc additionally comprises musical compositions from Grammy-nominated cellist and composer Tina Guo and producer Steve Mazzaro. NASA stated these might be “streamed from the area station to the Worldwide Astronautical Congress in October in Milan and to Abu Dhabi.”
Additionally onboard is the ARTEMOSS experiment, which is pronounced equally to “Artemis” in a nod to NASA’s Moon-bound program. The acronym stands for “From Antarctica to Area: Molecular Response and Physiological Adaptation of Moss to Simulated Deep Area Cosmic Ionizing Radiation and Spaceflight Microgravity.”
The experiment is a collaboration between NASA, the SETI Institute and the College of Florida. It makes use of a sort of moss present in Antartica, known as Ceratodon purpureus, and seeks to study extra about how some sorts of vegetation are higher in a position to thrive in situations highlighted by each cosmic radiation and microgravity.
“Not solely is moss a superb gravity-sensing system, however moss is essentially the most tolerant of radiation amongst vegetation,” stated Dr. Agata Zupanska, a analysis scientist on the SETI Institute throughout a prelaunch briefing hosted by the ISS Nationwide Laboratory. “It cannot solely survive, however actually thrive underneath doses and energies of radiation which can be deadly to different vegetation. And we introduced this somewhat bit additional as a result of we chosen Antarctic moss.”
She stated the sensible software of this analysis might be studying extra about learn how to shield different vegetation for deep area exploration to the Moon and Mars.
“What I consider we are going to study from ARTEMOSS is that not solely the vegetation, some vegetation, at the very least moss, are able to repairing regardless of the injury is attributable to the radiation. They’ll do it within the lowered gravitational setting,” Zupanska stated. “We hope to actually discover the mechanisms and the processes that do work and make a plant tolerant of these two environments (cosmic radiation and microgravity).”
The ISS Nationwide Lab is sponsoring greater than 25 experiments flying to the area station on this mission, together with ARTEMOSS and the Nanolab Astrobeat. One other such experiment is one designed to additional understanding of protein crystallization from Bristol Myers Squibb in partnership with Redwire Area.
“Protein crystallization is a manner for us to have the ability to higher perceive our crystal constructions, stabilize our proteins and develop suspension formulations to allow at-home use via subcutaneous administration, as a substitute of getting to go to an infusion middle,” stated Robert Garmise, the director of formulations growth and exploratory biopharmaceuticals at Bristol Myers Squibb in an ISS Nationwide Lab-produced video.
“The Redwire {hardware}, the Pillbox, permits us to deal with natural solvents on the Worldwide Area Station, that are required for the crystallization of our small molecule.”

The CRS-31 mission can even launch 39 student-led initiatives as a part of the Scholar Spaceflight Experiments Program (SSEP). Amongst these are an eighth-grade experiment from California on the consequences of microgravity on spinach, a Twelfth-grade experiment from Ohio on the hydration impacts of Liquid I.V. in microgravity and a Tenth-grade experiment analyzing worms as a attainable eco-friendly pest management in area.
Greater than science
Among the many supplies on board not explicitly for science are 377 kilos (171 kg) of spacewalk tools. For quite a lot of causes all year long, NASA has not been in a position to full a spacewalk from the ISS since NASA astronauts Jasmin Moghbeli and Loral O’Hara’s almost 7-hour mission on Nov. 1, 2023.
Tracy Dyson and Michael Barratt had been suited up for a spacewalk on June 24, however following depressurization, a water leak within the cooling unit of Dyson’s swimsuit prompted it to be cancelled earlier than they left the airlock.
The Dragon will carry with it an Worldwide Docking Adaptor Planar Reflector Meeting, which helps visiting spacecraft decide their approaching pace, remaining distance and place relative to the ISS. It’s set to be put in throughout an upcoming spacewalk someday in 2025.
Nestled throughout the 2,119 kilos (961 kg) of crew provides is a number of recent meals. With the Thanksgiving vacation developing later this month, there are some particular holiday-related treats as effectively.
