Good! Maybe it is not as innovative as some of the other rockets, but it is a real rocket which flew nicely from the first try. At the minimum this allows Europe to maintain independent access to space. And then there are European space startups that are getting very close to launching their own vehicles. This will be even more exciting!

To answer the question at ~ 48:14 about using propellant to cool turbine blades--The reason this is not done in rocket turbines is that the available coolant is SO cold that doing so sets up ;thermal strains in the blade section that are prohibitively high. In other words, the large thermal gradient produced by the cryogenic coolant does more harm than good. This has been studied a number of times. Air-breathing engines take care to use coolant air that is at the 'proper' temperature. Thank you very much.

I think for these legacy companies, ie ones that have been around since before 1990, recoverability instead of reusability would be a good stepping stone. Obviously with companies like space X who had reusability in mind from the start, continuing to develop that is easy, but for most of the older companies, the idea of reusability economically died with the space shuttle. so I think that a puch for recovering parts would be a good step publicity wise so they can say they aren't just dropping them in ocean, salvage whatever they can and scrap the rest. Edit* Also I believe that countries are really pushing for national projects, especially Europe, because while that may be more expensive, the investment is (more or less) staying in Europe. I don't think Arianne will be going anywhere

@Rob2 13 күн бұрын

The investment is made to secure a capability without being dependent on other nations. For a while, Europe decided to rely on Russia for launches, and we see how that turned out. Now they do not want to rely on USA or China either. With the expected volume of launches (5/year for Ariane 5, now target 10/year for Ariane 6 but it has to be seen if that becomes true), reusability is hard to get economically feasible.

Obsolete may be a little overstated. Sort of like Elon saying that buying a car without full self driving is foolish because it will soon be obsolete. SpaceX has proved that when done correctly reusability can greatly reduce costs. I don’t think ArianneGroup (or ULA or NASA for that matter) can currently do reusability in a cost effective way. That doesn’t make Arianne obsolete, it can still launch satellites from European territory which is a big plus for European countries. Although the cost is higher so there is more taxpayer involvement, but this allows them to continue developing their space capabilities, which likely will eventually venture into reusability, although probably more gradually like ULA is doing.

That "Vitesse" a.k.a. velocity must be relative to the ground because 7.5 km/s is not fast enough to stay in orbit at that altitude in a "fixed" reference frame.

@cogoid 14 күн бұрын

Usually one wants to show to the viewers a velocity which starts from zero at the launch pad. Anything else is too counter-intuitive. One common choice to achieve this is to show the velocity as reported by the on-board GPS receiver. That's what SpaceX does. GPS uses a coordinate system rotating with the Earth. So anything stationary on the ground shows as having zero velocity. Interestingly, in this coordinate system Geostationary satellites also have zero velocity.

@@cogoid I remember a launch to GEO where you could see the speed DECREASE all the time nearly down to zero, thinking "how is that possible" but finally realizing that it was earth-relative speed and zero is the right target.

it probably is at 350 km altitude and if that point is a slight apogee vs a say 180km perigee.

How come they didn't show the landing? ;P

The re-entry failed and is stuck in space… literally 🎉 Also, they don’t land… they sink in the ocean… when they can 😂

Looks like one of the booster separation engines didn't fire.

What are the surrounding towers for?

Lightning protection. Launch pads in the USA have very similar systems.

Didn't see the boosters land.

After the trips to the moon, there was a lung issue that came from breathing moon dust. Bringing out that info has some weight with people that think everything is fake. The heat shield tech may need some new ideas. The CPU heat sink using heat pipes has an idea that could be a solution to the surface cooling. Has anyone studied shapes to punch through the plasma to reduce the damage created by the plasma burn. I would want to test methods to re-enter at much slower speeds. There should be an easy way to break through that barrier. It would be funny if the solution is dropping an anchor from LEO.
