As of February 2020, a lunar stay during a Phase 1 Artemis mission will be about 7 days and will have 5 EVAs.
A notional concept of operations (i.e. a hypothetical but possible plan) would include the following: On Day 1 of the stay, astronauts touchdown on the Moon but do not conduct an EVA.
Instead, they prepare for the EVA scheduled for the next day in what is referred to as "The Road to EVA".
On Day 2, the astronauts open the hatch on the Human Landing System and embark on EVA 1 which will be 6 hours long.
It will include collecting a contingency sample, conducting public affairs activities, deploying the experiment package, and acquiring samples.
The astronauts will stay close to the landing site on this first EVA.
EVA 2 begins on day 3.
The astronauts characterize and collect samples from permanently shadowed regions.
Unlike the previous EVA, the astronauts will go further from the landing site (up to 2 km) and up and down slopes of 20°.
Day 4 will not include an EVA but Day 5 will.
EVA 3 may include activities such as collecting samples from an ejecta blanket.
Day 6 will have the two astronauts deploy a geotechnical instrument alongside an environmental monitoring station for in-situ resource utilization (ISRU).
Day 7 will have the final and shortest EVA.
This EVA will only last 1 hour rather than the others' 6 hours in duration from egress to ingress.
This EVA mostly comprises preparations for the lunar liftoff, including jettisoning hardware.
Once the final EVA is concluded, the astronauts will return into the Human Landing System and the vehicle will launch from the surface and join up with Orion/Gateway.
