I hope NASA won't forget to equip the new Ares I-X Rocket with CERAMIC tiles for re-entry!

Makes you wonder how lucky the Apollo program was having not experienced any difficulty with entering back into the atmosphere without the heat ceramic tiles the Shuttle had to use in order to re-enter, the lunar capsule could have literally melted, wow, those guys were really really really lucky!

Not the rocket....the capsule!!!

actually find it hard to believe that nasa would send anyone to space in such a rocket, clearly the first stage was still firing when the detach occurred causing the capsule and attached second stage to whip around 180 degrees just as nasa cut the video feed. Any astronauts inside the capsule during such a jack knife event would be torn apart. 3 minutes up and three minutes back down to earth or just three minutes then terminal whiplash... certain death another successful nasa launch... not

Also I can't understand why nasa is allowed to waste such huge amounts of money on such stupidity. There is zero reason to put men in space anyway, space is far to dangerous without a radiation shield, you'd have a better chance in dodging bullets at 100 yards...

Yes exactly. NASA forgot these tiles with the lunar capsule and the heat generated on re-entry can reach as high as 3,000 degrees F (1,650 degrees C), that's really really really hot. We extract metal at lower temperature melting it from rock those Apollo astronauts were really really really lucky their capsule didn't literally melt, that the parachute ejector didn't fuse and functioned accordingly. Phew!

Which part?

The part where the Apollo capsule had no HEAT RESISTANT TILES?

The part where the parachute ejector and floating device functioned WITHOUT A SNAG?

The part where re-entry REACHES 3,000 DEGREES F?

Which part?

well? which is it?

This is the re-entry vehicle:

NASA has selected Altair as the name of the lunar lander the Constellation Program will use to put humans on the moon.

Altair will be capable of landing four astronauts on the moon, providing life support and a base for weeklong initial surface exploration missions, and returning the crew to the Orion spacecraft that will bring them home to Earth. Altair will launch aboard an Ares V rocket into low Earth orbit, where it will rendezvous with the Orion crew vehicle.

WOW! The new lander will put FOUR people on the moon, instead of just two! WOW!

We sure have come a long way in the last 40 years!

Wow.

You don't do your homework do you?

HEAT SHIELD.

Don't understand what I'm talking about?

Go to the Air and Space museum.

Look at the capsule that is closest to the main entrance.

Look at the heat shield on the bottom of the capsule.

Look at the heat streaks on it.

Holy Shit! Thanks dude.

Somebody get on the horn or e-mail NASA and remind them not to forget the HEAT RESISTANT TILES on the Ares/Orion capsule needed for re-entry like the Shuttle needed and still needs until its decommissioned.

Dude don't get your feathers all ruffled-up, I'm just trying to divert a possible MAJOR malfunction.


True, the Apollo capsule has NO HEAT RESISTANT TILES which would have been needed to cool the Lunar-capsule on re-entry because temperatures rise to about 3,000 DEGREES F and that heat shield is made of metal which would have melted because metal melts at 3,000 DEGREES F.

It was only a test of the solid stage and separation...

Sorry it went over your head, but...

That's probably why they are rcoket scientists, and you are jacking off in your Mommy's basement...

Didn't anybody e-mail NASA?

I know someone who knows someone at NASA, I'll speak with him next occasion and tell him about the heat resistant tiles.

Its rocket science, but sometimes even rocket scientist can forget.

What a maroon.

It's not metal, and it DID melt. It was designed to melt!

I'll bet you don't even know how the tiles on the shuttle work, either. You think they stay cool, perhaps? No...they get blazing hot (hot enough to melt metals). But they are also great insulators. THEY get hot -- what is under them does not.

In very simple terms, the Apollo heat shield (practically identical design and material is used today on the Russian vehicles bringing crew back from the ISS), is ablative; it is intended to break up to carry heat away from the spacecraft (the actual mechanism is slightly more complex).

Actually, one could easily design a spacecraft that didn't need a heat shield. The various heat shields are not because space craft MUST get hot, they are because a heat shield masses much less than the fuel, and the rocket motors, to de-accelerate from orbital velocities. Instead of turning fuel into heat into expanding gas into velocity change, they turn velocity into pressure into compressed gas into heat that largely goes into the atmosphere.
