CAPE CANAVERAL, Florida — SpaceX successfully launched an uncrewed Dragon spacecraft for NASA right this moment (March 6), sending recent provides in opposition to the Worldwide Build Assign (ISS) — and additionally sticking one more rocket touchdown, the 50th for the firm overall.
The 2-stage Falcon 9 rocket former in right this moment’s flight is a outmoded; its first stage additionally lofted the outdated Dragon cargo mission, in December 2019. The rocket blasted off from Pad 40 here at Cape Canaveral Air Pressure Assign at 11: 50 p.m. EST (0450 GMT on Saturday, March 7), illuminating the skies above Florida’s Build Cruise.
Because the rocket roared to lifestyles, automobile alarms on the press space enjoy been caused, barely audible above the extra than 1 million lbs. of thrust generated by the rocket’s engines.

Approximately 8 minutes after liftoff, the booster’s engines relit as part of the touchdown direction of. Sonic booms cracked all the plot by the sky as the rocket caught its touchdown at SpaceX’s Landing Zone 1 facility at Cape Canaveral. SpaceX, which prioritizes the trend of reusable spaceflight systems, has now pulled off 50 such touchdowns all the plot by orbital missions to this level.
This Dragon capsule is a outmoded as properly, having reached the ISS twice sooner than, in February 2017 and December 2018. If all goes in accordance to concept, the capsule will arrive on the ISS for the third time early on Monday morning (March 9).
The mission that kicked off tonight, dubbed CRS-20, is the final flight below SpaceX’s first industrial resupply services contract with NASA, which change into signed in 2008 and is valued at $1.6 billion.
The major Dragon reached the ISS in 2012, becoming the major industrial spacecraft ever to enact so. Twenty flights later, this model of the Dragon will rapidly retire.
Starting up in October of this three hundred and sixty five days, all future resupply missions will characteristic SpaceX’s upgraded Dragon 2 capsule. That model will provide you the option to flying five times whereas every Dragon 1 change into rated to skim actual thrice.
Dragon 1 has to berth with the condominium house by job of robotic arm, whereas Dragon 2 will dock itself to the orbital outpost. The recent capsule functions many various upgrades as properly.
SpaceX has additionally constructed a crew-carrying capsule, called (accurately enough) Crew Dragon. Crew Dragon first flew a three hundred and sixty five days in the past, reaching the condominium house on SpaceX’s uncrewed Demo-1 mission. The crew spacecraft will rapidly skim astronauts to the orbiting lab on a mission called Demo-2, which can also originate as rapidly as early Could well unprejudiced. (SpaceX holds a multibillion-buck NASA contract to skim astronauts to and from the ISS. This deal is atomize free the firm’s cargo contract.)
Crew Dragon has special systems unfamiliar to carrying crew — shall we allege, lifestyles give a decide to systems, seats and a originate hotfoot system.
Tucked interior right this moment’s cargo Dragon is extra than 4,300 lbs. (1,950 kilograms) of provides, in conjunction with a bevy of research experiments that can give a decide to extra than 25 science investigations over the direction of the condominium house’s expeditions 62 and 63.
Integrated in that cargo is a particular experiment that can witness at how stem cells grow in microgravity. Researchers from Emory College in Atlanta purpose to mark how stem cells transition into heart muscle cells in microgravity. Such knowledge can also encourage in the therapy of heart disease, the No. 1 killer in the United States, NASA officials acknowledged.
One other investigation is calling at intestine characteristic. Researchers are sending tissue chips to the condominium house that can aid them better mark organ characteristic and the physique’s immune system response in traumatic cases.
Dragon is one of two uncrewed cargo vehicles for the time being gotten smaller by NASA to aid the condominium house stocked. The diversified is Cygnus, which is flown by Virginia-based mostly mostly firm Northrop Grumman.
Since Dragon first docked with the condominium house in 2012, the spacecraft has delivered extra than 95,000 lbs. (43,000 kg) of cargo and returned extra than 76,000 lbs. (34,475 kg) of research.
The spacecraft will stop on the condominium house for approximately a month sooner than returning to Earth with treasured research aboard.
