SpaceX’s Crew Dragon capsule will carry humans into orbit for the first time, in just three days. In preparation for that historic liftoff, it’s initial passengers — NASA astronauts Bob Behnken and Doug Hurley — put on their spacesuits for a trial run. 

The dress rehearsal was the final practice run ahead of the big day’s events. Behnken and Hurley, along with countless engineers and members of launch control teams across three centers, practiced what it would be like to conduct the actual launch.

The day started with Behnken and Hurley putting on their spacesuits, followed by the traditional walk out of the astronaut quarters. The duo posed for a few photos before hopping into their Tesla and driving off toward the launch pad. The white model X has been emblazoned with both NASA logs — the worm and the meatball.

Once at the pad, the two astronauts hopped into an elevator bound for the crew access arm, which towers 265-feet off the ground. The crew then boarded the Dragon capsule through a hatch on the vehicle’s side. After strapping in, the crew performed some system checkouts before proceeded with a simulated launch countdown.

The day’s activities encompassed what the crew will be going through on launch day, stopping just before the fuel is loaded on board. Once the test run was over, the crew disembarked from the Dragon, and rode in their Tesla  back to crew quarters.

The duo has named their Dragon spacecraft, but have decided to keep that name a secret until launch day. The naming of spacecraft goes back to the beginning of the space program.

With the final dress rehearsal in the books, the last major hurdle for SpaceX will be a launch readiness review on Monday. If all goes as planned and weather at the launch site cooperates, Behnken and Hurley will lift off on May 27 at 4:33 p.m. EDT.

SpaceX’s Starship V3 is almost ready and it will change space travel forever

SpaceX is targeting April for the debut test launch of Starship V3 “Version 3”

SpaceX is closing in on one of the most anticipated rocket launches in history, as the company readies for a planned April test launch and debut of its next-gen Starship V3 “Version 3”.

The latest iteration of Starship V3 has a slightly taller Super Heavy booster and Starship upper stage than their predecessors, and produce stronger, more efficient thrust using SpaceX’s upgraded Raptor 3 engines. V3 also features increased propellant capacity, targeting a total payload capacity of over 100 tons to low Earth orbit, compared to around 35 tons for its predecessor. With Musk’s lifelong aspiration to colonize Mars one day, the increased payload capacity matters enormously, because Mars missions require moving massive amounts of cargo, fuel, and eventually, people. But the most critical upgrade may be orbital refueling. SpaceX’s entire deep space architecture depends on moving large amounts of propellant in space, and having orbital refueling capabilities turn Starship from just a rocket into a true transport system. Without it, neither the Moon nor Mars is reachable at scale.

A fully reusable Starship and Super Heavy, SpaceX aims to drive marginal launch costs down and at a tenfold reduction compared to current market leaders. To put that in perspective, getting a kilogram of cargo to orbit today costs thousands of dollars. Bring that number down far enough and space stops being an exclusive domain. That price point unlocks mass deployment of satellite constellations, large-scale science payloads, and affordable human transport beyond Earth orbit. It also means the Moon stops being a destination we visit and starts being one we inhabit.

Elon Musk pivots SpaceX plans to Moon base before Mars

NASA expects Starship to take off for the Moon’s South Pole in 2028, with the ultimate goal of establishing a permanently crewed science station there. A successful V3 flight this spring keeps that timeline alive.  As for Mars, Musk has shifted focus toward building a self-sustaining city on the Moon first, arguing that the Moon can be reached every 10 days versus Mars’s 26-month alignment window. Mars remains the horizon, but the Moon is the proving ground.

Elon Musk hasn’t been shy with hyping the upcoming Starship V3 launch. In a social media post on Wednesday, he confirmed the first V3 flight is getting closer to launch. SpaceX also announced its initial activation campaign for V3 and Starbase Pad 2 was complete, wrapping up several days of cryogenic fuel testing on a V3 vehicle for the first time. The countdown is on. April can’t come soon enough.

FCC chair criticizes Amazon over opposition to SpaceX satellite plan

U.S. Federal Communications Commission (FCC) Chairman Brendan Carr criticized Amazon after the company opposed SpaceX’s proposal to launch a large satellite constellation that could function as an orbital data center network.

Carr made the remarks in a post on social media platform X.

Amazon recently urged the FCC to reject SpaceX’s application to deploy a constellation of up to 1 million low Earth orbit satellites that could serve as artificial intelligence data centers in space.

The company described the proposal as a “lofty ambition rather than a real plan,” arguing that SpaceX had not provided sufficient details about how the system would operate.

Carr responded by pointing to Amazon’s own satellite deployment progress.

“Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit,” Carr wrote on X.

Amazon has declined to comment on the statement.

Amazon has been working to deploy its Project Kuiper satellite network, which is intended to compete with SpaceX’s Starlink service. The company has invested more than $10 billion in the program and has launched more than 200 satellites since April of last year.

Amazon has also asked the FCC for a 24-month extension, until July 2028, to meet a requirement to deploy roughly 1,600 satellites by July 2026, as noted in a CNBC report.

SpaceX’s Starlink network currently has nearly 10,000 satellites in orbit and serves roughly 10 million customers. The FCC has also authorized SpaceX to deploy 7,500 additional satellites as the company continues expanding its global satellite internet network.

NASA watchdog says Starship development delays could affect Artemis timeline

The report noted that several technical milestones still need to be completed before Starship can serve as a crewed lunar lander.

A NASA watchdog report stated that continued development work on SpaceX’s Starship could affect the timeline for the agency’s planned Artemis moon missions. The report noted that several technical milestones still need to be completed before the spacecraft can serve as a crewed lunar lander.

The findings were detailed in a report from NASA’s Office of Inspector General, as noted in a report from Reuters.

NASA selected SpaceX’s Starship in 2021 to serve as the Human Landing System (HLS) for its Artemis lunar program. The vehicle is intended to transport astronauts from lunar orbit to the surface of the Moon and back as part of future Artemis missions.

According to the watchdog report, Starship’s development has experienced roughly two years of schedule delays compared to earlier expectations. Still, NASA is targeting 2028 for the first crewed lunar landing using the Starship lander.

One of the most significant technical milestones for Starship’s lunar missions is in-space refueling.

To support a crewed lunar landing, multiple Starship launches will be required to deliver propellant to orbit. Tanker versions of Starship will transfer fuel to a storage depot spacecraft, which will then refuel the lunar lander.

The report noted that this approach could require more than 10 Starship launches to fully refuel the spacecraft needed for a single lunar landing mission.

NASA officials indicated that demonstrating cryogenic propellant transfer in orbit remains one of the most important technical steps before Starship can be certified for lunar missions.

SpaceX has conducted 11 Starship test flights since 2023 as the company continues developing the fully reusable launch system. A 12th test flight, this time featuring Starship V3, is expected to be held in early April.
