The weather forecast remains unchanged for the planned Tuesday, Dec. 21, launch of SpaceX’s 24th commercial resupply services mission to the International Space Station for NASA.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 30% chance of favorable weather conditions for Tuesday’s targeted liftoff of a SpaceX Falcon 9 rocket and the company’s Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Less than favorable conditions are expected for the primary launch window early Tuesday morning, with the main concerns associated with this weather being the cumulus cloud rule, thick cloud layer rule, and surface electric field rule.

NASA commercial cargo provider SpaceX is targeting tomorrow at 5:06 a.m. EST, to launch its resupply services mission to the space station. The backup date for launch is Wednesday, Dec. 22, at 4:43 a.m. EST.

At noon today, NASA TV will broadcast a prelaunch news conference from the agency’s Kennedy Space Center in Florida for SpaceX’s 24th commercial resupply services mission. The event will feature representatives from NASA’s International Space Station Program, SpaceX, and the U.S. Space Force Space Launch Delta 45.

Participants include:

  • Joel Montalbano, manager for the International Space Station Program
  • Bob Dempsey, Acting Deputy Chief Scientist, International Space Station Program
  • Sarah Walker, director, Dragon mission management at SpaceX
  • Arlena Moses, launch weather officer, Cape Canaveral Space Force Station’s 45th Weather Squadron

Live launch coverage will air on NASA Television, the NASA app and the agency’s website, with prelaunch events starting Tuesday at 4:45 a.m. EST. Join us on the blog for live updates, or follow along on NASA TV or the agency’s website for the live launch broadcast.

NASA commercial cargo launch provider SpaceX’s Falcon 9 rocket – with the Dragon atop – was rolled out to the launch pad Sunday morning, Dec. 19, before being raised to a vertical position in preparation for Tuesday’s launch of SpaceX’s 24th commercial resupply services mission to the International Space Station. Liftoff of the Falcon 9 is scheduled for 5:06 a.m. EST.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron now predict a 30% chance of favorable weather conditions for Tuesday’s launch, with the cumulous cloud, thick cloud layer, and surface electric field rules remaining the primary weather concerns.

Dragon will deliver a variety of NASA science investigations, including a protein crystal growth study that could improve how cancer treatment drugs are delivered to patients, a handheld bioprinter that could one day be used to print tissue directly onto wounds for faster healing, an investigation from the makers of Tide that examines detergent efficacy in microgravity, and investigations from the Student Payload Opportunity with Citizen Science (SPOCS) program.

About 12 minutes after launch, Dragon will separate from the Falcon 9 rocket’s second stage and begin a carefully choreographed series of thruster firings to reach the space station. Arrival to the station is planned for Wednesday, Dec. 22. Dragon will dock autonomously to the forward-facing port of the station’s Harmony module, with NASA astronauts Raja Chari and Thomas Marshburn monitoring operations from the station.

The spacecraft is expected to spend about a month attached to the orbiting outpost before it returns to Earth with research and return cargo, splashing down off the coast of Florida.

Tune in to NASA TV or the agency’s website for live coverage of mission activities, beginning Monday, Dec. 20, at noon with the prelaunch news conference. Live launch day coverage starts Tuesday at 4:45 a.m. EST.

Houston, We Have a Pepper

Recently, the four chile pepper plants growing aboard the International Space Station in the Advanced Plant Habitat (APH) bore fruit – several peppers, in fact.

The peppers developed from flowers that bloomed over the past few weeks. Peppers are self-pollinating, and once pollination occurred, peppers started forming 24 to 48 hours later; however, not all pollinated flowers developed into peppers.

A unique feature of the APH is that it can be controlled remotely. To pollinate the flowers in orbit, the team at NASA’s Kennedy Space Center instructed APH to run its fans at variable rates to create a gentle breeze in microgravity to agitate the flowers and encourage the transfer of pollen. The space station crew also provided assistance by hand pollinating some of the flowers.

Studies of fruit development in microgravity are limited, and NASA researchers have noted lower fruit development versus ground observations in this experiment for reasons that are not fully understood at this point. Overcoming the challenges of growing fruit in microgravity is important for long-duration missions during which crew members will need good sources of Vitamin C – such as peppers – to supplement their diets.

The average length for this type of pepper is just over three inches in ground tests. Hatch chile peppers are a mild heat pepper that starts out as green and will ripen to red over time, but it’s unknown what effect microgravity will have on the length to which they grow and their potency.

Astronauts will perform two harvests this year – one at 100 days in late October, and one at 120 days in early November. At those times, astronauts will sanitize the peppers, eat part of their harvests, and return the rest to Earth for analysis.

Cargo Dragon Splashes Down in the Atlantic, Science Delivered to Kennedy

SpaceX Cargo Dragon spacecraft
SpaceX’s Cargo Dragon spacecraft is lifted aboard a recovery vessel after splashing down off the coast of Florida on Thursday, Sept. 30, 2021. The capsule, carrying cargo that flew aboard NASA’s SpaceX 23rd commercial resupply services mission, undocked from the International Space Station Thursday at approximately 9 a.m. The event marked the first time a Cargo Dragon splashed down in the Atlantic Ocean.

SpaceX’s Cargo Dragon spacecraft completed a successful parachute-assisted splashdown off the coast of Florida around 11 p.m. EDT on Thursday, Sept. 30. The capsule undocked from the station’s forward port of the Harmony module Thursday at 9:12 a.m., completing the voyage in approximately 14 hours.

This marked the first time Cargo Dragon splashed down in the Atlantic Ocean. The proximity to the coast of Florida enabled quick transportation of the science aboard the capsule to NASA Kennedy Space Center’s Space Station Processing Facility, delivering some science back into the hands of the researchers hours after splashdown. The shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects.

Dragon launched Aug. 29 on a SpaceX Falcon 9 rocket from Launch Complex 39A at Kennedy, arriving at the station the following day. The spacecraft delivered more than 4,800 pounds of research investigations, crew supplies, and vehicle hardware to the orbiting outpost.
