Some screen captures.

22 launches of something we built. Helped build Cygnus. Do the berthing adaptors. Protected Juno mission from radiation. 20 millions rads coming into Jupiter. Dreamchaser can land on any airport that can a B737 or A320. FAA certified Houston and Huntsville airports. 12 other airports working to get certified. By folding wings can return in C-5 cargo plane.

For Dreamchaser carho took out all things that are not needed for human spaceflight. Took out ECLSS and abort motors. 5500 kg cargo capacity. Cargo module burns up. 15 to 20 times reusability. None of this works if we don't do the primary mission well. Looking at what else we can do. That's a pretty interesting list. Provide a vehicle, rocket and training. Integration experience. Come home at  1.6g. Leave home at breakfast and be home at dinner. 6 to 10 hours. Created full interior mockup of vehicle in a module fashion. Be able to quickly change modules. Can carry up to 1500 kg of exterior payload in 500 kg bays.

Some captures from the presentation.

NASA. We don't think we could have lost another one. We have contingency supplies. For CRS-2 its about the same. A little more oversight for reliability and launching on time. A lot of complaints of the delays which is a big cost expense for the payloads. Station was prepared. Commercial payloads hurt more. Redundancy in CRS2. We did not overbuy. Capability to add missions if we need to. Launch on need capability. Bring up another vehicle quickly. Right now go with the missions we have if everything went according to plan. Have an ability to surge.

In this presentation, it was confirmed that the first missions of cargo DC will berth (not dock). However, Angela Hart from NASA said "at least in the initial vehicles" which implies that it could change later on (at 5m40s of the video).

UN News: UNOOSA is looking to launch the first UN mission to outer space. Tell us about that.

Simonetta Di Pippo:
We have started to understand that access to space is really important for developing countries to be part of this space community and to get more and more benefits from being part of this process.

We are working with the Sierra Nevada Corporation, which has developed the Dream Chaser vehicle. This is quite an interesting spaceship because it goes up as a normal space object and comes back as a normal plane so it can land on a normal landing strip. What we are trying to do now is to put together a mission which should fly, we hope, by the end of 2021. The current baseline is for two weeks in orbit and it could bring between 25-30 experiments. So the announcement of opportunity, which I hope will be out in the second half of 2017, will be open essentially to developing countries, but also to others. The experiments will be selected with the main criteria being that they have to be in line with the Sustainable Development Goals (SDGs).

Officials Mull Proposal for Manned Mission to Refurbish Hubble Telescope:
https://www.wsj.com/articles/officials-mull-proposal-for-manned-mission-to-refurbish-hubble-telescope-1486927198

WSJ is pay walled, so went looking and found this... while not directly related to Dream Chaser, as a tech demonstrator of potential instrumentation that could be uses on that space craft... it takes speculation from paper to hardware already existing...

Here are some of the relevant parts:

Quote from: Pasztor
President Donald Trump’s advisers are considering an industry proposal to send a manned spacecraft to repair and upgrade the Hubble Space Telescope within the next few years, according to people familiar with the matter. The discussions are still preliminary [...]

The Hubble repair proposal also has garnered administration officials’ attention because it appears to meet still other important White House criteria, according to these people. The goal is to put a lid on federal expenditures for space by fostering public-private partnerships, while devising projects that can be completed within the president’s current four-year term.[...]

The company twice presented its proposal to transition officials, according to one person familiar with the details.[...]

An administration representative declined to comment, except to say that transition officials lacked power to approve new projects and “it will be the responsibility of the NASA administrator to set NASA policy.” [...]

SNC's Dream Chaser Arrives at NASA Armstrong

NASA Armstrong Flight Research Center

Published on Feb 17, 2017
Sierra Nevada Corporation delivered its Dream Chaser spacecraft Jan. 25, 2017, to NASA's Armstrong Flight Research Center in California, located on Edwards Air Force Base. The spacecraft will undergo several months of testing at the center in preparation for its approach and landing flight on the base's runway.

The test series is part of a developmental space act agreement SNC has with NASA’s HYPERLINK Commercial Crew Program. The upcoming test campaign will help SNC validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.

The Dream Chaser is also being prepared to deliver cargo to the International Space Station under NASA’s Commercial Resupply Services 2 (CRS2) contract beginning in 2019. The data that SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.

I take it this means a crewed version still might be possible in the future.
