SpaceX to launch dozens of satellites on Transporter-1 flight Friday and you can watch it live

CAPE CANAVERAL, Fla. — SpaceX is preparing one of its veteran rockets to launch a stack of small satellites into space on Friday (Jan. 22). You can watch the fiery action live online. 

A two-stage Falcon 9 rocket flight is scheduled to take off from Space Launch Complex 40 at Cape Canaveral Space Force Station here in Florida. Liftoff is expected during a one-hour window that opens at 9:24 a.m. EST (1424 GMT). 

Perched atop the 230-foot-tall (70 meters) launcher are dozens of satellites as part of a dedicated rideshare mission. This cosmic carpool, known as Transporter-1, will also be ferrying 10 of the company’s own Starlink satellites into space and depositing them in a polar orbit — a first for the growing network of broadband satellites. Other payloads include 48 Earth-observing SuperDove satellites for Planet and one small nanosatellite called “Charlie” for Aurora Insight.

Friday’s launch marks the third mission of 2021 for SpaceX and the second in just two days from Florida’s Space Coast. The California-based rocket manufacturer launched a different Falcon 9 on a record-breaking flight on Wednesday (Jan. 20) to deliver a full stack of 60 Starlink satellites into orbit. 

The booster used on that mission became the first in SpaceX’s fleet of frequent fliers to launch and land eight times. (The previous record was seven, which was held by two different first-stage boosters.) 

Following liftoff on Friday, the Transporter-1 Falcon 9 rocket’s first stage is expected to land on SpaceX’s drone ship “Of Course I Still Love You,” which is waiting out in the Atlantic. If successful, it will mark the 73rd recovery of a first-stage booster for SpaceX.  

It will also mark the first catch of the year for the veteran drone ship, which has sat out the past two missions while being refurbished.

The Falcon 9 rocket for the Transporter-1 launch  is a four-time flier and a record-setter as well. Known as B1058, this flight proven booster will embark on its fifth flight and, if all goes according to plan, will be able to stick its landing at sea.

B1058 made history in May when it launched two NASA astronauts — Doug Hurley and Bob Behnken — to the International Space Station on the first crewed flight to launch from U.S. soil since the retirement of the space shuttle program in 2011. 

Emblazoned with NASA’s iconic worm logo, the booster also ferried a communications satellite for South Korea’s military, a batch of Starlink satellites and  a Dragon cargo capsule to the ISS for SpaceX’s 21st cargo resupply mission.  

For its next mission, the veteran will serve as a kind of space Uber, delivering a group of small satellites into orbit as part of SpaceX’s rideshare program, which aims to help smaller satellites get into space by sharing a ride much like an Uber pool. 

SpaceX announced the program in August 2020, offering rides on a Falcon for $1 million a pop. The launch slots are booked through the company’s website and are offered on regular intervals approximately four times per year. 

Rideshares missions are not exactly new for SpaceX as the company launched more than 60 satellites from its California launch pad in December 2018. That mission, dubbed SSO-A, delivered a small armada of satellites into low-Earth orbit through a carefully choreographed orbital ballet so that the satellites did not collide with one another. 

Since then, SpaceX has ferried other payloads to space on a few of its Starlink missions. Those missions included small cubesat satellites for Planet and BlackSky

SpaceX’s two net-equipped boats — called GO Ms. Tree and GO Ms. Chief — will be part of the recovery team deployed for this mission. They will attempt to recover the two pieces of the rocket’s nose cone, known as the payload fairing, after they fall back to Earth.

The dynamic duo supported the Starlink mission earlier this week and are currently en route to the Transporter-1 mission’s designated landing zone. (Each fairing half is equipped with parachutes and on board navigation software that steers it to a specific landing zone out in the Atlantic Ocean.)

For the Starlink mission, the boats scooped the pieces out of the water and will likely do the same thing for this mission. That determination will be made officially on launch day. 

Currently, weather forecasts predict an 80% chance of good conditions for the launch opportunity on Friday, with the only weather concerns being the potential for thick clouds over the launch site. There is a backup launch time on Saturday if need be. However, the launch conditions deteriorate a bit to just a 60% chance of good weather.

SpaceX aborts several Starship static fire attempts, rolls test tank to the pad

Accidentally producing the polar opposite of Starship serial number 9 (SN9) completing a trio of Raptor ignition tests in four hours last week, SpaceX has now suffered three back-to-back static fire aborts on January 20th.

On January 13th, Starship SN9 somewhat successfully ignited its Raptor engines three separate times with zero hands-on human intervention or inspection. While an impressive feat, SpaceX CEO Elon Musk soon revealed that two of the rocket’s three engines were damaged during the test campaign. NASASpaceflight.com later reported that the company had detected an issue with one Raptor after the first three-engine static fire, ultimately firewalling it and performing the next two static fires with only two engines.

SpaceX initially allotted five days to replace the two damaged Raptors (SN44 & SN46), scheduling road closures (a telltale sign of test plans) on January 18th, 19th, and 20th. Windows on the 18th and 19th went by with zero attempts. Finally, on the 20th, SpaceX kicked off Starship SN9’s first real test attempt since the engine swap around 2pm but it was aborted by 3pm.

After an extremely brisk recycle, Starship likely made it less than a minute away from ignition but the second attempt was ultimately aborted around 3:40 pm.

Two hours later, after SpaceX extended the end of its road closure from 5pm to 8pm, Starship SN9’s third Raptor static fire attempt was also aborted – once again just a minute or less away from ignition.

SpaceX held Starship SN9 for another hour or so after the third abort but ultimately began final detanking and depressurization around 6:50 pm, marking the end of the day’s attempts.

It’s impossible to say what caused Wednesday’s back-to-back-to-back aborts or if the three instances were connected. While potentially frustrating to watch from the sidelines, it’s crucial to remember that the public is getting a truly unprecedented continuous view of SpaceX’s process of developing and refining a world-class launch vehicle. Additionally, every abort Starship suffers should theoretically produce volumes of valuable data that both Starship and Raptor teams can use to better understand how to design, build, test, and operate the cutting-edge vehicle and its engines.

More likely than not, SpaceX is leaning towards caution (and thus cautious hardware and software limits) while attempting to prepare Starship SN9 for its true data-gathering purpose – an SN8-style high-altitude launch and landing attempt.

SpaceX is currently scheduled to try again with another series of Starship SN9 static fire attempts between 8am and 5pm CST (UTC-6) on Thursday, January 21st.

Meanwhile, prior to SN9’s multiple Wednesday aborts, SpaceX rolled the latest in a series of Starship ‘test tanks’ from the factory to the launch pad. A team rapidly strapped the tank to the concrete pad and connected it to ground support equipment in preparation for a series of tests that will likely end with SpaceX intentionally pressurizing the tank until its bursts. If successful, it will open the door for future Starships to save weight by cutting steel skin thickness from 4mm to 3mm.

Stay tuned for updates on both active test campaigns.
