To say what's going to happen, French does exactly what English does: aller + an infinitive. No new endings to learn.

Pronoun	Near future of partir (to leave)
je	vais partir
tu	vas partir
il / elle / on	va partir
nous	allons partir
vous	allez partir
ils / elles	vont partir

• Je vais voyager en France. — I'm going to travel in France.
• Il va pleuvoir. — It's going to rain.

Only aller changes; the infinitive stays as it is. This futur proche (near future) is what you'll hear most in conversation — for tonight, tomorrow and next year alike.
