SpaceX is only hours away from a Monday launch which should render the company with almost 250 Starlink satellites in orbit — that the hottest in several recent steps towards prime time for the space net constellation.
Agree to lift off no earlier than (NET) 9:49 am EST (14:49 UTC) on January 27th, a twice-flown Falcon 9 booster, new upper stage, 60 Starlink satellites, and a strangely blank payload fairing will try to thread the needle out of SpaceX’s Cape Canaveral Air Force Station (CCAFS) LC-40 pad. Weather is tepid according to USAF forecasts and Monday’therefore – already only 50% ‘go’ – doesn’t account for upper-level winds which will have to wane before Falcon 9 will start.
SpaceX’s fourth dedicated launch, today’s mission – known as Starlink V1 L3 (the third launch of v1.0 satellites) – will raise the number of spacecraft that the business has placed in orbit into 240. Based on previous statements from executives and SpaceX’s very own Starlink.com website, successfully completing Starlink V1 L3 could set the provider just a hop, skip, and a jump from the space-based online constellation’s prime-time. With a little luck, the satellite internet provider could be serving clients considerably sooner than anyone could imagine.

As of now, it appears that SpaceX will try to launch later now that weather conditions may induce the company to attempt again on January 28th. Fortunately, SpaceX’s exceptional operating systems brings with it a good amount of versatility to wash launches with outcome less than 40 minutes.

SpaceX can wait that long out of absolute necessity. The business introduced the use of ‘subcooled’ liquid oxygen and kerosene on its own Falcon launch vehicles all of the way back in 2016, encouraged by the fact that its propellant gets considerably denser as it gets colder. From toeing the line between liquid oxygen and kerosene actually solidifying into slush, SpaceX managed to boost Falcon 9’s payload capacities by an extraordinary ~30% or more. To get that benefit, yet, Falcon 9’s propellant need to remain as cold as you can, and it begins warming the moment that it renders its own far-more-insulated storage tanks also enters Falcon 9.

Consequently, SpaceX should load Falcon 9 and Falcon Heavy with propellant as late as physically possible, translating to no sooner than 35 minutes prior to liftoff on newest releases. In other words, if the weather is still securely about the ‘poor ’ side of things in T-38:00-35:00, SpaceX is frequently able to scrub a given launch attempt prior to propellant loading begins, both conserving the enemy in an unnecessary environmentally cycle and rescue propellant which may otherwise have to be wasted.
20 times, 120 satellites
Weather challenges as well as the likelihood of a 24-hour delay apart, SpaceX will launch its third batch of updated Starlink v1.0 satellites — also the firm ’s fourth dedicated launch of 60 spacecraft. If things proceed as planned, SpaceX may have launched almost 250 satellites total – all but 5 (or so) of which are happily operating in Earth orbit at the moment.

Deemed Starlink V1 L3, a mission later now will also indicate that SpaceX has launched an unbelievable 120 spacecraft – weighing greater than 30 metric tons – in less than 20 days. It’s ’s difficult to say for sure, however, it’s quite probable that that will indicate the most recent global record secured by SpaceX, following on the heels of the firm ’s current ascendance as the newest owner of the planet ’s biggest personal satellite constellation (~180 satellites).
On the other hand, the ultimate aim of Starlink is, obviously, to deliver unprecedentedly high-performance online service to clients everywhere on Earth. The “anywhere on Earth” modifier is likely greater than 20 committed SpaceX launches from fact, however, the company has stated it will begin serving net to clients from “the Northern U.S. and Canada in 2020”. Due to mid-2019, SpaceX indicated that that regional North American beta evaluation could begin after only six launches.
More recent remarks by a SpaceX executive imply that it may require more like 8 launches of 60 Starlink satellites until first service can begin in North America, but this ultimately suggests that the firm should be no longer than 50-65% of their way there later Starlink V1 L3. With a little luck, that could indicate that SpaceX is two or three Starlink launches from encouraging the very first non-employee customers on the firm ’s net. Given SpaceX’s launch cadence, six Starlink launches may well be well behind the business by the end of February – maybe a month or less in now.
