Mission

Missions progress the game storyline and allow Ryder to explore the Heleus Cluster and some of its planets. Most missions reward Ryder with XP, AVP, planetary viability, or a combination of the three. Some missions are purely character narrative, rewarding in their own right.

Acquisition
Missions are acquired in a number of ways.
 * Some are automatically added when the previous or prerequisite mission has been completed: A Better Beginning begins automatically when the last objective of Nexus Reunion has been completed.
 * Some are triggered by emails: Task: The Witnesses begins when Ryder reads Wisdom, an email from Moshae Sjefa.
 * Some are acquired through conversation: Speaking to Dr. Harihn in the Angaran Resistance Base begins Medical Caches.
 * Some are discovered: Task: Naming the Dead is acquired when Ryder finds one of the bodies associated with the mission.
 * Some have multiple methods of acquisition: If Ryder fails to respond to Captain Dunn's email, Contagion will be automatically added to the Journal the next time Ryder arrives at the Nexus.
 * Some may be prompted by an alert such as an email but require additional actions before acquisition: All of the missions in the Movie Night Line are acquired after talking to a crew or squad member, though all of these missions have associated emails alerting Ryder to the mission's availability.
 * Some are indicated by the Map symbol . This map symbol shows up when there is the potential to acquire a new mission.

Mission Types
Priority ops are the backbone of the story. While they don't necessarily provide the greatest XP rewards, they do provide the largest AVP rewards, making the largest contribution toward the goal of the Andromeda Initiative. Completing most priority ops adds star systems to the Galaxy Map, adding opportunity for adventure.

Allies and relationships missions add to the richness of the story but aren't required to be completed. Romance and loyalty missions fall into this category. Many of these missions are smaller and mostly narrative, providing a glimpse into a squad or crew member's personal life. These smaller missions, for the most part, tend to have no XP or viability rewards.
 * Allies and relationships

Heleus assignments deal with the issues and concerns of the major planets/starships. All vault missions and outpost establishment missions are Heleus assignments. These missions vary in difficulty, range, and reward. All except Monkeys in Space5 provide XP, most provide some AVP and planetary viability.
 * Heleus assignments

Additional tasks are optional missions that range from very short to very lengthy missions. The XP rewards range from +270 XP to +1330 XP. Some include viability rewards, some include monetary rewards. The small rewards of these missions individually doesn't amount to much but this category has sixty-two missions, which can add up quickly. It should be noted that some of these missions are prerequisites for Heleus assignments.
 * Additional tasks

This category is for any missions that have been completed. Some missions, such as Task: Researching Remnant, autocomplete and can only be found in this category.
 * Completed missions

There are a number of missions that don't appear in the five categories of the Journal for various reasons.
 * Uncategorized
 * There is a broken mission that can't be started.
 * There are a number of "ghost" missions that display on-screen but don't appear in the Journal. These are really alerts or warnings rather than missions.
 * Miscellaneous missions that don't appear in the Journal or on-screen.
 * Non-journal missions that show up on screen but not in the Journal such as A Job for Danny Messier.
 * Sub-missions that are part of another mission such as Take Down the Architect, a set of objectives common to all four Remnant Architect missions.
