SpaceX successfully launches cargo Dragon to ISS
Capitalism in space: SpaceX today successfully launched a cargo Dragon to ISS.
The first stage booster successfully landed on its drone ship in the Atlantic Ocean.
This Falcon 9 rocket and Dragon capsule were entirely new, making their first flights. This was the first new Falcon 9 to fly since November 2020, with sixteen launches during that period using reused boosters exclusively.
In fact, since November 2020 SpaceX has completed a total of 21 launches, all done in less than seven months. Moreover, the company has scheduled 34 (!) more launches through the rest of the year. If they achieve this ambitious schedule, they will complete 51 launches in ’21, more than doubling their previous annual record of 25 set last year. With all other American companies added in, there will be a good chance the United States launch total could exceed 70, breaking the country’s own annual launch record set in 1966 at the height of the first space race.
The leaders in the 2021 launch race:
17 SpaceX
15 China
8 Russia
2 Rocket Lab
2 ULA
The U.S. now leads China 23 to 15 in the national rankings.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I wonder if Falcon has enough throw to get to ISS in just a couple of orbits, like the Russians have done with Progress and Soyuz in the past.. I assume such a mission would have to be done with an expendable booster.
Any rocket scientists out there than can answer?

It’s not a matter of “throw.” It’s a matter of phasing. All the thrust in the world won’t get you there any faster if the ISS isn’t where it needs to be when you launch.
Liked ” . . . first space race.”
Klystron,
It isn’t so much the ability of the launch vehicle as it is the methods used for the rendezvous. Note that the booster had enough leftover propellant to make a boost back burn to land closer to the coast than when they don’t do a boost back burn. That propellant could have been used for more throw. Also note that this launch occurred on time, so mkent’s phasing reference could have been closer to the ISS for a faster rendezvous. It was a conscious choice to have a day and a half approach.
There may be a time in the future when these other spacecraft rendezvous faster. For now, they spend some amount of time in safer orbits, a bit farther away from the ISS.
This has been without west coast launches. They are prepping Vandenburg site for regular starlink. So long as Viasat does not succeed in blocking the next layer of Starlink cadence should increase even more.
