The fourth annual Neutrino Day science festival will be held Saturday, July 9, at the Sanford Underground Laboratory at Homestake in Lead.

The festival celebrates new experiments being installed 4,850 feet underground in the former Homestake gold mine, where Nobel Prize-winning neutrino research was done from the 1960s to the 1990s.

The Saturday adventure begins at the Homestake Visitor Center at 160 W. Main Street in Lead, at the Open Cut. Science buffs can take a shuttle up the mountain to the Sanford Lab surface campus, beginning at 8:30 a.m. Shuttles run about every 15 minutes until 12:30 p.m. While you wait for the bus, visitors can learn about geology and gold panning from Sanford Lab geologists. The last shuttle returns to the Visitor Center at 1 p.m.

Visitors can talk live, via the Sanford Lab's high-definition videoconference system, with scientists working a mile underground.
Activities include:

  • Fascinating science demonstrations, featuring nanotechnology, by SDPB's Science Guy - Steve Rokusek.
  • Mini-lectures every hour:
    • Photography Underground, Where Photons Are Scarce (9 a.m.) bySteve Babbitt, professor of photography at Black Hills State University
    • Building Mega-Caverns Bigger Than Mount Rushmore (10 a.m.), by Dr. Bill Roggenthen, South Dakota School of Mines and Technology
    • Detecting Signals from Supernovas (11 a.m.) by

    • The Worldwide Race to Detect Dark Matter (Noon), by Dr. Dan Akerib, Case Western Reserve University
  • Hands-on activities for the young and young at heart.
  • A chance to meet scientists, engineers and technicians building the Sanford Underground Laboratory.
  • Tours of the Yates Hoist Room, where visitors will don hard hats to see the massive motors and giant cable drums that carry people and equipment up and down a 5,000-foot shaft.
