Summits and poles

Having trekked to Mount Everest base camp and reached the summits of a number of notable mountains, including five of the world's fourteen 8,000-meter peaks, including summiting two eight thousanders back-to-back just 8 days apart, O'Brien decided to build on her passion for mountaineering and set herself the challenge of achieving the Explorer's Grand Slam. The Explorer's Grand Slam entails reaching the Seven Summits, the North and South Poles, as well as meeting the Three Pole Challenge.

Challenger Deep

Vanessa joined Caladan Oceanic's Ring of Fire expedition to the Pacific Ocean to survey the bottom of the three pools that constitute Challenger Deep in partnership with NOAA. On 12 June 2020, Victor Vescovo and Vanessa descended to the "Eastern Pool" of Challenger Deep spending three hours mapping the bottom, with the dive scanning approximately one mile of desolate bottom terrain, finding that the surface is not flat, as once was thought, but sloping, and by about 18 ft, subject to verification.

Other sports

After taking the American Red Cross flag to the North Pole in 2013, O'Brien completed the Boston Marathon in 2017 to help the American Red Cross raise over $512,000 for charity.
