# Requesting a service as Scientist
Open the space details by clicking on the space name in the main view.
Fig 2.1. Offer for scientists - opening space details At this moment, you are displayed with a view specific for a Scientific space. There are no active services yet, but you can apply for a service from the offer. As you can see, there are two offers available for this type of space:
- Trial grant for Eagle cluster - allows you to try the infrastructure with the limited number of granted resources
- Access to HPC cluster 'Eagle' for Scientists - allows you to request for a regular grant; use this option when you have a specific research work that requires significant resources.
The procedure of accessing for the Trial offer is very similar to the procedure of applying for Student's space, so let's demonstrate the second option.
Fig 2.2. Offer for scientists - space details Now you can see quite detailed information about the offer. One of the important aspects worth noticing is that the offer is free of charge, but you will need to settle the use of the service with a list of publications. Moreover, you need to be aware that access to resources will not be granted automatically: your request will be reviewed by the chairman of Users' Council and evaluated taking into account scientific value and declared amount of requested resources. If you agree with the conditions, click Activate to continue the process of application for the offered service.

Firstly, you need to select one of the three high-level options for a grant size: Small, Medium or Large. Once you have made your selection, you can further refine your expectations. For a matter of simplicity, we will select the first option with default settings.
