Wait until an SLS goes up (if it ever does).
Indeed Eric, it is fascinating, can't wait to see something launch close up! smile

Seemed to be a longer than usual delay between ignition and liftoff ?

The Progress is in orbit but its solar panels may not have deployed properly.

I have a funny feeling that its knackered. They lost one a couple of years ago when it went into a tumble immediately after it got into orbit.

Will it be visible over the UK this evening?

If its tumbling it should be obvious.

Confirmed that it never made it properly into orbit. It has already re-entered the atmosphere and burned up.

Another little update.

It re-entered over Siberia so the chances of seeing it tumbling across the sky over Farnborough were precisely Zero.

Cant help but think the commentater is narrating for a group of school kids!

I was amazed of how quick that went up! Would be nice to know what the G-forces involved were.

Did not realise that was a solid fueled 1st stage.

Apart from the rapid departure, you can tell from the dense white smoke trail that it is a solid rocket.

Have a look at the exhaust from a Space Shuttle compared to a Saturn V and you will see the difference.

There are variations in the plumes from different types of liquid fuelled rockets too - depending on what fuels are being used.

The Saturn V used Liquid Oxygen and kerosene as its propellants. It therefore burned fairly cleanly although it did have a bright yellow flame and a thin brown hazy smokey trail.

The Space Shuttle Main Engines ran on Liquid Hydrogen and Liquid Oxygen which burned even cleaner with no visible smoke trail and the only real byproduct of the combustion process was water vapour. The Delta IV heavy runs on a similar combination and leaves no noticeable trail at all.



The other type of liquid propellants are those which are hypergolic. In other words, they ignite on contact with each other and don't need a separate ignition system. These propellants are pretty nasty and they definitely do leave a smokey trail - one it is best to keep well clear of. Examples of hypergolic fuels are hydrazine and red fuming nitric acid.

Rockets such as the Russian Proton and the now retired American Titan family used such engines -
