Noob Question on Contract

[Tacitus275]

So I just start playing KSP... I am on my 3rd contract, "Hauling a RT-5 Flea Booster above Kerbal"

During the ascent, I fulfill all of the requirements, but then as I descend, I cease fulfilling those requirements....

How do you fulfill this contract?

[Superfluous J]

You need to fulfill them all at the same time. Just getting everything one by one isn't enough.

What exactly are the requirements? Generally they are a certain speed and altitude, along sometimes with a situation (sub orbital, orbital, flying, etc).

Is it truly a "haul" contract and not a "part test" contract?

I’ll go through it step by step:

1. Do you have the right part? Check on the launchpad that the ‘have xxx part’ criterion is checked, otherwise there’s no point trying to meet the rest.
2. What do you need to do with it? Just have it there (these are usually called ‘haul xxx into flight/orbit’) or run a test (usually called ‘test xxx in flight/orbit)? If it’s the latter then you need to either right-click the part once all other criteria are met and then hit ‘run test’, or activate the part through the staging list.
3. Where? There’s usually an altitude range e.g. between 3km and 10km or 200,000m-250,000m.
4. How fast? Like altitude, there’s often a speed range for these contracts e.g. between 100m/s and 300m/s.

If you think you’re achieving everything the contract is asking for but it doesn’t complete, get a screenshot (F1 key, they go in KSP/screenshots), upload it to a sharing site like imgur and then post it here; there’s a button on the bottom right of the reply box to add an image link, or you can just paste the link directly into your reply as text.

What version of KSP are you using? Unlikely to be relevant but sometimes these contracts ask for old, deprecated versions of the parts which you can’t access any more and are only kept for compatibility reasons.
