For the first time, SpaceX will launch one of its reusable Falcon 9 boosters for a 20th time Friday night on a flight to deliver 23 more Starlink Internet satellites to orbit.

This milestone mission is scheduled to lift off at 9:22 pm EDT Friday (01:22 UTC Saturday) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. Forecasters from the US Space Force predict "excellent" weather for the primetime launch.

Falcon 9 will blaze a familiar trail into space, following the same profile as dozens of past Starlink missions.

This is the rocket that literally lights itself on fire before it heads to space. It's the world's largest rocket entirely fueled by liquid hydrogen, a propellant that is vexing to handle but rewarding in its efficiency.

The Delta IV Heavy was America's most powerful launch vehicle for nearly a decade and has been a cornerstone for the US military's space program for more than 20 years. It is also the world's most expensive commercially produced rocket, a fact driven not just by its outsized capability but also its complexity.

Now, United Launch Alliance's last Delta IV Heavy rocket is set to lift off Thursday from Cape Canaveral Space Force Station, Florida, with a classified payload for the National Reconnaissance Office, the US government's spy satellite agency.

Anyone who has tracked the development of Blue Origin's New Glenn rocket has been waiting for signs of progress from the usually secretive space company. On Wednesday, engineers rolled a full-scale New Glenn rocket, partially made up of flight hardware, to a launch pad in Florida for ground testing.

The first New Glenn launch is almost certainly at least six months away, and it may not even happen this year. In the last few years, observers inside and outside the space industry have become accustomed to the nearly annual ritual of another New Glenn launch delay. New Glenn's inaugural flight has been delayed from 2020 until 2021, then 2022, and for now, is slated for later this year.

But it feels different now. Blue Origin is obviously moving closer to finally launching a rocket into orbit.

One of the largest launch pads at Cape Canaveral Space Force Station will become vacant later this year after the final flight of United Launch Alliance's Delta IV Heavy rocket. SpaceX is looking to make the sprawling facility a new home for the Starship launch vehicle.

The environmental review for SpaceX's proposal to take over Space Launch Complex 37 (SLC-37) at Cape Canaveral is getting underway now, with three in-person public meetings and one virtual meeting scheduled for March to collect comments from local residents, according to a new website describing the plan .

Then federal agencies, led by the Department of the Air Force, will develop an environmental impact statement to evaluate how Starship launch and landing operations will affect the land, air, and water around SLC-37, which sits on Space Force property on the Atlantic coastline.

A lot goes into a successful rocket launch. It's not just reliable engines, computers, and sophisticated guidance algorithms. There's also the launch pad, and perhaps even more of an afterthought to casual observers, the roads, bridges, pipelines, and electrical infrastructure required to keep a spaceport humming.

Brig. Gen. Kristin Panzenhagen, commander of the Space Force's Eastern Range at Cape Canaveral Space Force Station in Florida, calls this the "non-sexy stuff that we can't launch without." Much of the ground infrastructure at Cape Canaveral and Vandenberg Space Force Base in California, the military's other launch range, is antiquated and needs upgrades or expansion.

“Things like roads, bridges, even just the entry into the base, the gate, communications infrastructure, power, we’re looking at overhauling and modernizing all of that because we really haven’t done a tech refresh on all of that in a very long time, at least 20 years, if not more," said Col. James Horne, deputy director for the Space Force's assured access to space directorate.

CAPE CANAVERAL, Florida—Right out of the gate, United Launch Alliance's new Vulcan rocket chased perfection.

The Vulcan launcher hit its marks after lifting off from Florida's Space Coast for the first time early Monday, successfully deploying a commercial robotic lander on a journey to the Moon and keeping ULA's unblemished success record intact.

"Yeehaw! I am so thrilled, I can’t tell you how much!" exclaimed Tory Bruno, ULA's president and CEO, shortly after Vulcan's departure from Cape Canaveral. "I am so proud of this team. Oh my gosh, this has been years of hard work. So far, this has been an absolutely beautiful mission."

Welcome to Edition 6.19 of the Rocket Report! While we wait for SpaceX to launch the second full-scale test flight of Starship, a lot of the news this week involved companies with much smaller rockets. Astra is struggling to find enough funding to remain in business, and Virgin Galactic says it will fly its suborbital Unity spaceplane for the last time next year to focus on construction of new Delta-class ships that should be easier to turn around between flights. It's a tough time to raise money, and more space companies will face difficult decisions to stay alive in the months ahead.

As always, we welcome reader submissions , and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Virgin Galactic plans "pause" in flight operations. Virgin Galactic will reduce the frequency of flights of its current suborbital vehicle and stop them entirely by mid-2024 as it concentrates resources on the next generation of vehicles, Space News reports . This was unexpected news for anyone outside of the company. As Ars has previously reported , Virgin Galactic has ramped up the flight rate for its VSS Unity suborbital spaceplane to about one mission per month, a rather impressive cadence, especially when Blue Origin, the other player in the suborbital human spaceflight market, has not flown any people to space in more than a year.

The first two prototype satellites for Amazon's broadband network are ready for launch Friday from Florida, the first in a series of at least 77 rocket launches the retail giant has booked over the next six years to deploy a fleet of more than 3,200 spacecraft to rival SpaceX's Starlink system.

These first two satellites for Amazon's $10 billion Internet megaconstellation, called Project Kuiper, will take off on top of a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida. The two-hour launch window opens at 2 pm EDT (18:00 UTC).

You can watch the launch from Cape Canaveral with the YouTube video embedded here.

Airspace and maritime navigation warnings released to pilots and mariners suggest the US military might launch a hypersonic missile this week on a test flight from Cape Canaveral, Florida.

This test could be one of the final milestones before the US Army fields the nation's first ground-based hypersonic weapon, which is more maneuverable and more difficult for an enemy to track and destroy than a conventional ballistic missile. Russia has used hypersonic in combat against Ukraine , and US defense officials have labeled China as the world's leader in emerging hypersonic missile technology.

That has left the US military playing catch-up, and the Army is on the cusp of having its first ground-based hypersonic missiles ready for active duty. If informed speculation is correct, the test launch from Cape Canaveral Space Force Station this week—performed in partnership between the Army and the Navy—could be a full-scale test of the new solid-fueled hypersonic missile to propel a hypersonic glide vehicle to high speeds over the Atlantic Ocean.
