SpaceX launched practically 4 dozen satellites and landed the returning rocket Monday (Feb. 21) on a mission that tied the corporate’s booster-reuse document.
A two-stage Falcon 9 rocket topped with 46 of SpaceX’s Starlink broadband spacecraft lifted off from Cape Canaveral House Pressure Station in Florida at 9:44 a.m. EST (1444 GMT), hovering into a transparent, blue sky. Â
About 9 minutes after liftoff, the Falcon 9’s first stage got here again right down to Earth for a vertical landing on SpaceX’s droneship A Shortfall of Gravitas, which was stationed within the Atlantic Ocean just a few hundred miles off the Florida coast. It was the a hundredth Falcon 9 rocket touchdown for SpaceX and the corporate’s 107th touchdown general, together with touchdowns by Falcon Heavy boosters. (The corporate aced its a hundredth general touchdown again in December.)
“Nice information general, we at the moment are awaiting the deployment of our 46 Starlink satellites which is scheduled to happen about an hour from now,” SpaceX manufacturing supervisor Jessie Anderson stated throughout reside commentary after the launch. SpaceX ended its reside webcast earlier than satellite tv for pc deployment due the shortage of floor station video hyperlinks with the satellites, Anderson added.

Monday’s flight was the eleventh launch and touchdown of this explicit Falcon 9 first stage, Anderson stated. That tied SpaceX’s reuse document, which was set by a special Falcon 9 booster throughout a Starlink launch in December.Â
The Falcon 9 first stage on this flight, referred to as Starlink 4-8, beforehand launched SpaceX’s Crew Demo-2 flight (the corporate’s first astronaut flight for NASA in 2020), in addition to the Anasis-II satellite tv for pc mission for South Korea, CRS-21 house station cargo mission for NASA, Transporter-1 and Transporter-3 rideshare missions and 5 completely different Starlink missions, SpaceX has stated.Â
The 2 halves of the rocket’s nostril cone, or payload fairing, additionally made return journeys to house on the flight, every flying on their third mission, Anderson stated.Â
“Enhancements on the fairings and our general refurbishment course of has decreased the impression of water landings dealt with to an general fairing restoration price of 93% over the past 14 missions,” she added.
SpaceX had already launched three massive Starlink batches this yr — two in January and one on Feb. 3. The Feb. 3 mission bumped into severe hassle, nonetheless, due to a photo voltaic eruption, which triggered a geomagnetic storm right here on Earth.Â
That storm elevated atmospheric density, boosting drag on the newly launched Starlink satellites. In consequence, as much as 40 of the 49 spacecraft got here crashing again to Earth, SpaceX representatives stated.
SpaceX is outwardly concentrating on a better orbit during which to launch its new Starlink satellites on right now’s flight, in response to Spaceflight Now, which diminished the variety of satellties from 49 to 46. They are going to be deployed in a near-circular goal orbit that may vary between 202 miles and 209 miles (325-337 kilometers) at its highest and lowest factors, Spaceflight Now reported.
The bottom altitude for the satellites misplaced within the photo voltaic storm was about 130 miles (210 km), SpaceX has stated. The corporate deliberately deploys its giant batches of Starlink satellites into low orbits in order that they’ll fall again to Earth and expend within the ambiance to keep away from creating house particles in the event that they endure a malfunction in orbit.
SpaceX has already launched about 2,100 Starlink satellites to orbit, with greater than 200 falling from orbit from failures or decommissioning, in response to Spaceflight Now. However the firm is much from executed. SpaceX has approval to launch 12,000 Starlink craft and has utilized for permission from a global regulator for as much as 30,000 extra.
The corporate’s Starlink web satellite tv for pc mission goals to supply high-speed web entry to prospects anyplace on Earth, particularly in underserved or extraordinarily distant areas of the planet the place web service is tough to acquire.
Monday’s launch was initially scheduled for Sunday (Feb. 20), however SpaceX pushed it again a day attributable to unhealthy climate for rocket restoration operations.
The profitable launch and touchdown marked SpaceX’s seventh house mission of 2022 and the fourth devoted to Starlink launches. It was the corporate’s thirty eighth Starlink mission and 145th launch general, Anderson stated.Â
Editor’s be aware: This story was up to date at 10:32 a.m. EST to report the profitable launch of SpaceX’s Starlink 4-8 mission. It was additionally corrected to notice that the mission carried 46 Starlink satellites into orbit, not 49.
