Do you know what NASA has inside these spheres?

Nothing.

They’re vacuum spheres which are used to generate the pressure drop to drive Langley’s hypersonic wind tunnels.

NASA also operates the Space Power Facility the largest ‘nothing’ on earth.

Nobody beats NASA at nothing.

One of my favorite spacecraft designs will always be the Eagle Transporter from Space: 1999.

It looked practical, believable, and completely unlike the sleek spaceships I was used to seeing as a kid.

50 years later, I still think it's a fantastic design.

So far it's handled a couple of hundred guests without leaning over, but we'll see how it does! You should get a live process list that updates every 5 seconds.

If you connect from anywhere far away, let me know, I'm curious!

The spiral galaxy NGC 4698 is more chaotic than its appearance may suggest…

Not only is it one of a few known spiral galaxies with a bulge that extends out from its disc at a right angle – the stars and gas nearest its centre also rotate perpendicular to the rest of the disc! 1/2

This is one of the most punishing certification tests any airliner must survive - Rejected Takeoff (RTO)

For certification, Boeing accelerates the 777 to just below V1 at around 775,000 lb (351 tons), then cuts thrust and applies maximum braking. The airplane has seconds to go from full power to a complete stop.

The sideways drift comes from pure physics: enormous inertia, uneven tire grip, and an anti-skid system riding the edge of a skid. Brake temperatures spike until they glow, and fuse plugs in the wheels are designed to let the tires deflate safely if they get too hot.

Vídeo do X-15 de quando dava ruim - O veloz North American X-15 foi o mais rápido "artefato voador com uma pessoa dentro" de seu tempo, alcançando e superando Mach 6,72 (cerca de 7.274 km/h) durante os voos de testes a que foi submetido.

Dados do X-15

Velocidade máxima: chegou a Mach 6,72 (cerca de 7.274 km/h), superando com folga o limite do Mach 5.

Altitude máxima: bateu o recorde de 108,9 km de altura, permitindo que seus pilotos recebessem asas de astronauta.

Período de testes: realizou 199 voos entre 1959 e 1968 pela NASA e pela Força Aérea dos Estados Unidos.

Pilotos famosos: 12 pilotos voaram nele, incluindo Neil Armstrong, antes de ir para o programa Apollo.

Combustível: propelente líquido.

O avião-foguete North American X-15 era transportado e lançado debaixo da asa direita de um bombardeiro B-52 modificado (chamado de aeronave-mãe).

O Processo de Lançamento

Acoplamento: O X-15 ficava preso firmemente a um suporte especial instalado sob a asa direita do B-52, perto da raiz da asa, para suportar o peso elevado da aeronave experimental.

Decolagem: O B-52 decolava com o X-15 preso à sua asa, com o piloto já dentro da cabine do avião-foguete desde o solo.

Voo de Cruzeiro: O bombardeiro subia até atingir a altitude planejada de lançamento, que ficava em torno de 45.000 a 50.000 pés (cerca de 13,7 a 15,2 quilômetros de altura).

Liberação e Ignição: quando o B-52 chegava ao local e à altitude corretos sobre a área de testes (geralmente sobre a Base Aérea de Edwards, na Califórnia), o piloto do X-15 dava a ordem ou o comando era acionado, fazendo o X-15 se desprender do suporte.

Aceleração: após cair por alguns segundos para se afastar com segurança do bombardeiro, o piloto ligava o potente motor-foguete do X-15 e disparava rumo aos limites da atmosfera.

A Meeting of Giants: A Rare Shot from the Voyager Archives 🛰

In this historic image, the moons Europa and Io are captured against the backdrop of Jupiter’s Great Red Spot. The scale is impressive: the giant storm—which has been raging on the gas giant for centuries—could easily swallow the entire Earth, while the passing moons vividly illustrate the colossal size of the Solar System's largest planet.

Imagine kids watching Buck Rogers expecting a Star Wars-style adventure, then Pamela Hensley rocks up looking like this. And spandexed Erin Grey was in the wings. Despite the costumes and suggestive dialogue, it received a PG to maximise its audience
