NASA's Genius Solution to Launch NEW Space Plane Replace Shuttle...
Amid Boeing's troubles that kept delaying Starliner, Sierra Space's Dream Chaser is like a ray of light in the night sky.
Not disappointing us, Sierra Space and NASA recently brought encouraging news for the only winged commercial spacecraft destined for the International Space Station - it has reached the final testing milestones before a firm launch schedule late in 2024.
So what future awaits Dream Chaser's inaugural flight?
Although Dream Chaser almost fell into the same pitfalls as Boeing's Starliner, how did Sierra Space overcome these difficulties?
Let’s find out on today’s episode of Alpha Tech:
NASA's Genius Solution to Launch NEW Space Plane Replace Shuttle...
On May 18, inside a climate-controlled shipping container from NASA's Neil Armstrong Test Facility in Sandusky, Ohio, the Dream Chaser spacecraft, named Tenacity, arrived at Kennedy and joined with its companion cargo module, Shooting Star, which had arrived on May 11.
NASA's Genius Solution to Launch NEW Space Plane Replace Shuttle...
Upon arrival at Kennedy, teams moved the Dream Chaser Tenacity to the high bay inside the Space Systems Processing Facility, where it will undergo final testing and processing before its anticipated launch later this year.

Thanks for the video, and the great narration. The narration is also very friendly sounding right to the final goodbye.

[jwalkerC]

should never have allowed Mcdoanald Douglas to buy Boeing, that's when the cost-cutters cut the bone out.

[keithhoward]

why wouldn't they incorporate the Shooting Star solar power generators and cargo bay into the space station, or save it there for the new space stations that are being planned? Why just throw away good new equipment?

[michaelshore]

Brilliant they have re invented the Dynasoar of 50 years ago

[theboatgoat]

Excellent video, really comprehensive, thanks!

[Markv]

Hopefully if the heat tiles function properly, may SpaceX can learn something from them that might fix their heat tile problem.

[nah]

Your channel has gone from strength to strength! Do keep it up

[grantmcbride]

It's surprising that a space and science channel wouldn't include metric alongside the imperial measurements.

[michaelbruno]

Glad this is finally approaching launch, it and the manned version will be fantastic to see. Maybe the manned version could even eventually service Hubble again?

[TimothyLipinski]

Great Video ! The Sierra Space Dream Chaser is what the NASA Space Shuttle should have been ! The Cargo Dream Chaser Test Flight and then the six contracted Cargo Flights are to be launched on the ULA Atlas 5 rocket to the ISS ! The Dream Chaser is contracted to return to the runway at the KSC in Florida with important Cargo from the ISS ! After the seven Cargo Flights to the ISS, the Cargo Dream Chaser will be FREE to UP-Grade to the Crew Dream Chaser and launch with a human rated ULA Vulcan Centaur rocket to the ISS or a new low inclination LEO CSS ! Also the Dream Chaser is contracted to permit the Dream Chaser to land at Spaceport America in the State of New Mexico if needed ! tjl

Another method of getting a smaller vessel with crew and delicate cargo into orbit is high altitude spin-launch. You might think a spin-launch is high pressure but there is a way around it (pun intended). Let's say you use two helium balloons to lift an adjoining bar with the launch vehicles to between 30 and 40 kilometers of altitude (which is reasonable). The air thins very quickly with altitude and so there will be very little wind resistance. At the center of the bar is a spindle upon which two vessels are attached. As it spins, it begins extending a tether so that each launch vehicle. There are two so they counter-balance each other (call them ying and yang). The spindles speed may remain constant as their velocity will automatically increase as the tethers are extended. Once the speed sufficient for orbital insertion is acquired then you ship the crew/cargo module down the tether to meet each launch vessel and snap into it then immediately detach from the tether. The crew/cargo module would glide by centrifugal force (unpowered) such that it will naturally not feel any (or no significant) G force during acceleration. In fact, the only force felt will be deceleration after release due to wind resistance. However, this will be minimal as the air is very thin and only gets thinner with altitude. It's a very simple system but also very inexpensive and very eloquent.

I have a personal goal (as a fun project) to work out a design for a self-launching long-duration habitable space vessel for under $100K in materials, something possible for a common man to build and launch. It didn't seem possible for a long time but, after many concepts and iterations, I really feel like I have something. It's two counter-rotating discs with computer-controlled magnetic separation of an axel component (shaped like a spindle of thread) that joins the two. There are coils and magnets between the two so that energy can be drawn from the counter-rotation. The rocket engines (concentric pressure chambers with H2+O2 combustion on the inner chamber and liquid water to steam in the outer chamber) are located at three hardpoints on the outer perimeter of the discs. The release pressure as they spin around to the desired angle for lift. The rotation provides stability during launch and so no gimbaling is necessary at all. The hull is made of four layers of aramid fabric with two layers of polyurethane. The outer layer is aluminized aramid with open space between it and the next layer. This keeps the heat off, keeps the aramid from decay due to UV rays, and provides a pocket for regolith storage. The inner membrane is PVC truss-core and flooring -- commercial off-the-shelf. The fuel and propellant is liquid water with baking soda for electrolysis. The counter-rotation of the discs easily produce sufficient electrical energy for continuous electrolysis to fee the hydrogen combustion in a JIT manner. This is cooled by the outer pressure chamber through steam production, also generating thrust. This is similar to the main engines on the space shuttle, actually. The math works out for sufficient energy production and thrust when at scale of at least roughly 30 meter radius (better margins with larger size). The closest margin is the large amounts of liquid water required. Under the flooring of the design is the sewer/water-treatment system. At launch, the whole perimeter area interior may be used to store liquid water. The rotation will act like a turbo pump. Once in orbit, power generation would be through sterling generators. The axel component would hold the crew during launch (should be zero vibration for them). The combination of aramid and polyurethane is both highly protective against cosmic rays and solar flare radiation and also ballistics. The combination of aramid fabric and polyurethane has a synergistic effect providing improved ballistics protection. It is also quickly and easily repairable in the event of a puncture. It is highly insulative and air-tight... and light weight with very high tensile strength.

If starliner is broken again and can't fly for months put dream chaser on the rocket Boeing was going to use and see if it will work

[Carlsbaddest]

The word 'genius' should NEVER be used in the same sentence as nasa. I would not let a single person employed at nausea (aka nasa) look after a dead goldfish.

[peterwoodhouse]

Please use Centigrade so the world can understand

[bobbylineberry]

Why not design. The cargo modules to be dual purpose. Instead of burning them up make them part of the new station coming up instead of throwing out millions of dollars as useless expensive garbage. Just the fuel to get the module uo there is bingo pissed away . Start being better stewards of our money.

[georgeageorgopoulos]

OK Let's go to Moon NASA!? What is your Moon Space Tech???? You cant do it!!! ;))
