The Omaze Star Trek Beyond charity campaign is still going strong, and there’s still one week left for you to donate $10 for the chance to win a set visit and a walk-on role. The latest promotional video from the set of Star Trek Beyond pays tribute to the late, great Leonard Nimoy, with an appropriate Spock salute.

The Omaze campaign combines nine charitable causes under one umbrella — every $10 you donate not only makes you eligible to win a set visit and walk-on role, but it also helps several charities at once. Zachary Quinto hosts the latest video, in which he pays tribute to his predecessor by highlighting a charity that was very close to Nimoy’s heart: the St. Jude Children’s Research Hospital.

Each week the cast has taken us behind the scenes to get fans excited about the Omaze campaign, but this week’s video is the most sincere and heartfelt yet. The video ends with the cast of Star Trek Beyond offering the customary Vulcan “Live long and prosper” salute.

If you haven’t been paying attention, here’s a quick rundown of the Omaze campaign, which ends on September 1: your $10 contribution goes to the nine charities selected by the cast of Star Trek Beyond. The Star Trek: To Boldly Go grand prize winner will receive a flight to Vancouver and a stay in a four-star hotel, a visit to the set to meet the cast and crew and check out the filming process, and a professional hair and makeup transformation for your walk-on role as a Star Trek character.

Additionally, a winner is selected each week during the course of the campaign for a special set visit and meet-and-greet with the cast, including Quinto, Chris Pine, Simon Pegg, Anton Yelchin, John Cho, Zoe Saldana, Karl Urban, Idris Elba and Sofia Boutella.

Star Trek Beyond hits theaters on July 8, 2016.
