SpaceX efficiently launched a spaceship full of science to the space station Saturday following a climate scrub.
A Dragon cargo spacecraft carrying SpaceX‘s twenty sixth business resupply mission launched for the International Space Station (ISS) Saturday (Nov. 26) at 2:20 p.m. EST (1920 GMT). The launch, which was SpaceX’s 54th general launch and fifth Dragon launch of 2022, got here after an try on Nov. 22 was scrubbed by bad weather (opens in new tab).
“Stunning launch, as all the time, nice to see that,” NASA spokesperson Sandra Jones mentioned through the launch’s dwell broadcast.
Docking on the ISS is scheduled to happen on Sunday (Nov. 27) at 7:30 a.m. EST (1230 GMT) with protection accessible right here at Area.com, courtesy of NASA, beginning at 6 a.m. EST (1100 GMT). When Dragon arrives on the orbiting laboratory, it can dock to the zenith, or space-facing, port of the space station, the place it can stay for about 45 days.
“Go Falcon and comfortable Thanksgiving, ISS,” launch personnel mentioned at lift-off.

At present’s launch was the primary flight for each the Falcon 9 and Dragon, an uncommon prevalence for SpaceX. As deliberate, about eight minutes after launch, the Falcon 9’s first stage touched down on the drone ship “Simply Learn the Directions” stationed within the Atlantic Ocean.
Dragon carried 7,700 kilos (3,500 kilograms) of cargo throughout at the moment’s launch. A few of the payloads on board embody dwarf tomatoes, a microscope to take a look at modifications in crew immune techniques, liquid resin tech to create larger constructions, solar energy arrays, {hardware} to seize pictures of astronaut eyes and a system to create vitamins from easy-to-carry space meals like yogurt, NASA officers wrote in a release (opens in new tab).
With NASA having just launched its Artemis 1 uncrewed mission to the moon Nov. 16, making ready for long-duration excursions underneath the Artemis program would require rethinking the way to provide astronauts with meals and hold them wholesome for weeks or months, not solely on a space station, but additionally on the moon.
Veggie is a sequence of experiments that has been exploring rising all types of crops in space, and even flowers like zinnias. At present’s Dragon carried the newest installment, dubbed Veg-05 (opens in new tab), which is bringing Crimson Robin dwarf cherry tomatoes to the ISS. The investigators are significantly drawing classes discovered from efficiently maturing chili peppers final fall, Gioia Massa, NASA’s space crop manufacturing scientist and principal investigator of Veg-05, advised Area.com throughout a information convention Nov. 9.
“To this point, that is the longest plant progress experiment we have had on the space station,” Massa mentioned of the chili peppers. “It was 135 days, and the astronaut pollinated the fruit. We obtained an amazing quantity of information. We discovered higher methods to fertilize as a part of that.”

Veg-05 investigators are looking for methods of lowering astronaut time on the crops, as previous experiments have required handbook watering and monitoring. “Pillow” reservoirs will likely be used for the dwarf tomatoes, very like with previous crops of lettuce and zinnias. (The “pillows” confer with baggage that include fertilizer and a soilless substance, packed right into a wicking floor, that encourages progress with a minimal of mess.)
“Tomatoes will likely be a brand new journey for us on the Veggie staff, attempting to determine the way to hold these thirsty crops well-watered with out over watering,” Massa mentioned. Astronauts will eat the tomatoes in orbit to see how they style, and investigators are already discussing the way to higher the physics of watering for low-gravity environments on the moon or Mars, she added.

Along with the host of science tools, Dragon is carrying extra solar arrays as much as the space station to proceed upgrading energy on the orbiting complicated. The ISS base arrays have been put in through the station’s first main phase of development within the early 2000s. Over time, arrays in space naturally degrade, producing much less energy, and the entire arrays on the ISS are working past their 15-year design life.
The 2 new solar arrays, known as iROSAs (ISS Roll-Out Photo voltaic Arrays), are designed to be deployed atop the unique arrays to partially overlay the bigger, authentic constructions. There are six iROSA installations deliberate; astronauts have already put in two and mounted {hardware} for 3 extra throughout a spacewalk on Tuesday (Nov. 15).
The brand new arrays can generate 20 kilowatts of energy and when working with the still-exposed elements of the older arrays they cowl, the space station’s electrical energy provide needs to be boosted by 20% to 30%. The 2 new iROSAs are scheduled to be put in throughout spacewalks starting on Dec. 3, NASA has mentioned.

The 2021 spacewalks that put in the primary two iROSAs had solely minor points, together with bracket interference when unhinging the arrays and small bucklings within the sunshades used to forestall overheating. The 2 arrays aboard the present mission have a redesigned hinge and stronger sunshades to forestall the issue from occurring once more, Matt Mickle, Boeing’s developmental initiatives senior supervisor, advised Area.com throughout the identical information convention.
“We have examined these minor modifications on the bottom, and … we’re assured that may guarantee a greater deployment this time,” he mentioned. The 2 presently put in iROSAs, he added, have had barely higher energy generated than anticipated.
NASA, which is dedicated to the ISS until at least 2030 and hopes different companions will signal on past 2024, is engaged on upgrading these arrays to not solely present solar energy for present experiments and station wants, but additionally to increase these capabilities for the rising business companions on the complicated.
