The caption of the DC-201 in orbit image has some additional details.

Quote from: the caption
Differentiated from the DC-100 series by a 40% increase in size, upper body windows and fixed wings, the redesigned DC-200 is expected to be flight-tested without a crew in late 2025 - and with astronauts onboard in 2026. Although design details are yet to be finalized, the DC-200 is likely to be configured with lower body-mounted wings and twin-canted tails, similar to the Boeing X-37, and will feature a simpler outer mold line without the pronounced upper-body hump of the baseline version.

A view of the Dream Chaser 100 and 200, the latter being the crewed version.https://twitter.com/sierraspaceco/status/1611432910438993930

The caption of the image in the AviationWeek article also says: "For the next-generation crewed DC-200 series, Sierra Space is studying a twin-tail, fixed-wing design."

The DC 200 series is indeed the crewed version (see this article and the attached image):
https://spaceexplored.com/2022/01/05/sierra-space-shows-off-full-size-dream-chaser-mockup-at-ces-2022/
The listing of national security in the Sierra Space Dream Chaser chart as one of the intended purposes for all three Dream Chaser variants reminds me of the fact that at one time in the late 1960s Martin Marietta proposed a derivative of the unmanned SV-5D (X-23) lifting body to be used for reconnaissance to serve national security interests, which never materialized. The US Space Force and NRO would be more than happy to consider operating the Dream Chaser if initial launches of the DC-100 variant are successful, because the USSF could eye a military version of the Dream Chaser to either augment or replace the X-37B and the NRO will almost certainly recognize the reconnaissance potential of the Dream Chaser.

I visited Sierra Space last May and was told that the crew version would be ~40% longer than their cargo version. Maybe it’s just an optical illusion but the vehicle on the right appears smaller. Or the exec didn’t know what they were talking about.

Look at the shadows on the ground. The one on the right is further away so it appears smaller but is probably bigger.

@DutchSatellites

As expected multiple sources have reported over the past several weeks that
@SierraSpaceCo
 Dream Chaser is no longer manifested on
@ulalaunch
 Vulcan flight #2. Primary reason is yet another set of delays in getting Dream Chaser ready for flight.

If the second Vulcan launch won't be used to launch the first orbital Dream Chaser, the question is whether it will be repurposed for the launch of USSF-106.

Some news: Dream Chaser’s debut is delayed until at least mid-December. This extends NASA’s reliance on Falcon 9 for crew *and* cargo. More critically, it also raises questions about Vulcan’s launch manifest and path to certification.

Seems they're working on new TPS for (what I assume to be) either DC 200 or an upgrade to DC 100:

Sierra Space Trains NASA’s Jasmin Moghbeli and JAXA’s Satoshi Furukawa for Dream Chaser® Spaceplane Mission to International Space Station
MAY 23, 2023|   NEWS

Japan Aerospace Exploration Agency designated Furukawa as a member of Crew-7 early Monday morning

LOUISVILLE, Colo. – May 23, 2023 – Sierra Space, a leading, pureplay commercial space company building the first end-to-end business and technology platform in space, announced today it has achieved another significant milestone in the journey to the first flight of Dream Chaser®. The company hosted its first-ever official training for astronauts from NASA and JAXA to learn the innerworkings of the world’s first commercial spaceplane.

The astronauts – Jasmin Moghbeli (United States) and Satoshi Furukawa (Japan) – are two members of the upcoming SpaceX Crew-7 mission to the International Space Station (ISS). During their planned six-month stay, Dream Chaser will make its maiden voyage to deliver cargo to the ISS as part of NASA’s Commercial Resupply Services-2 (CRS-2) contract.

“We are honored to provide NASA cargo resupply missions to the International Space Station. The astronaut training is another important milestone as we complete the final preparations for Dream Chaser’s first mission,” said Sierra Space CEO Tom Vice. “Our team provided a comprehensive training experience for these Crew-7 members to prepare them for when Dream Chaser berths at the ISS.”

Sierra Space compiled an eight-hour training session that took place on March 7 at the company’s Louisville, Colorado facility. Company specialists conducted the training, which was divided into four sections. Parts 1 and 2 were classroom training, while Parts 3 and 4 involved a full-size mock-up of Dream Chaser:

Part 1: Dream Chaser Overview – Sierra Space team members gave Moghbeli and Furukawa a full briefing on Dream Chaser. Topics covered included systems identification and function, mission profiles (from launch and rendezvous to reentry and landing), crew interfaces and operations (i.e., types of cargo, how to load/unload, etc.). At the end of Part 1, astronauts walked away with a full understanding of the hardware they will encounter on Dream Chaser once it is at the ISS.

Part 2: Rendezvous and Proximity Operations (RPO) – This portion of the training covered required actions as Dream Chaser makes its approach and officially berths with the ISS. Sierra Space employees carefully reviewed the timeline, profile and procedural operations of the high-level system configuration involved in this critical part of the mission.

Part 3: Dream Chaser Hardware Familiarization and Scenarios – The astronauts moved into a full-size mock-up of Dream Chaser. As they walked through the vehicle, Sierra Space employees identified hardware/systems and taught the astronauts how to operate and/or interface with each one. The astronauts also learned vehicle ingress/egress procedures, as well as discussed off-nominal scenarios.

“This was the portion of the training where the astronauts were blown away by Dream Chaser’s massive size, often commenting, ‘Wow, you can fit a lot of cargo in here,’” said Krista Abler, with Sierra Space’s Flight Operations Mission Training team. “You can look at CAD drawings or read about Dream Chaser’s dimensions all day long. But its immense capacity doesn’t really register until you crawl inside. I think this is a reason why NASA is excited about our vehicle.”

Part 4: Cargo Transfer Scenarios – During the final portion of training, the astronauts learned how to properly and safely install/remove cargo from Dream Chaser, using the same procedures and operational tools as they will on orbit. They practiced with numerous restraints (i.e., straps, beams, etc.), identified hazards associated with cargo operations and ran scenario drills.

“This was probably the most important lesson of the day because the whole point of Dream Chaser coming to the ISS is to deliver cargo,” Abler said.

Sierra Space’s Dream Chaser® Spaceplane Comes to Life
MAY 31, 2023

Dream Chaser, the World’s First Commercial Spaceplane, Powers Up Achieving a Major Step Forward in Realizing the Vision of Sustainable Commercial Space Travel

LOUISVILLE, Colo. – May 31, 2023 – Sierra Space, a leading, pureplay commercial space company building the first end-to-end business and technology platform in space, is thrilled to announce the successful power up of its revolutionary Dream Chaser® spaceplane.

Dream Chaser represents a groundbreaking leap in space transportation technology, designed to provide reliable and cost-effective access to space for a wide range of applications. With its unique lifting body design, the spaceplane combines the flexibility of an aircraft with the capabilities of a spacecraft, revolutionizing space travel.

The power-up of Dream Chaser signifies the activation of its integrated systems, showcasing the culmination of years of rigorous engineering, design, and testing. Sierra Space simulated the power that will be generated from Dream Chaser’s solar arrays once on orbit. Test engineers plugged that power into Dream Chaser and began turning on systems. Sierra Space exercised flight computers, base processors and low-voltage distribution units.

“This is a milestone that points to the future and is a key moment in a long journey for Dream Chaser.” said Tom Vice, CEO of Sierra Space. “With this significant achievement, our Dream Chaser spaceplane is poised to redefine commercial space travel, opening up new possibilities for scientific research, technological advancements, and economic opportunities in space.”

The successful test was a key moment for the progress of space technology after years of design and development across Sierra Space, enabled by the accomplishments of many teams from system level design to final assembly and test.

Dream Chaser is a reusable, fully autonomous, orbital spaceplane designed to transport cargo to low-Earth orbit (LEO) destinations such as the International Space Station (ISS) and land at conventional runways. Measuring about one-quarter the size of the Space Shuttle, it features autonomous launch, flight, and landing capabilities with a smooth 1.5 low-G re-entry on compatible commercial runways worldwide.
