Vanessa Audi Rhys O'Brien was born on 2 December 1964 and grew up in Grosse Pointe Farms, Michigan.

O'Brien attended New York University School of Professional Studies (SPS) where she received her Bachelor of Arts in Economics and Executive MBA in Finance from New York University Stern School of Business.^[17] Vanessa O'Brien was named one of the Top 10 most famous NYU Stern MBA's in 2021.^[18]

O'Brien worked as a Director of Finance and Business Development for Morgan Stanley, Barclays Bank, and the Bank of America.^[19][20]

O'Brien is an Honorary Advisory Board member of the Scientific Exploration Society.^[21] She is also a Community Ambassador for the outdoor equipment company, Arc'Teryx, Soho, New York, and a Goodwill Ambassador for Pakistan,^[22] an Honorary Ambassador of the US Nepal Climbers Association Inc.,^[23] and is an active member of The American Alpine Club. O'Brien previously held board positions at The Explorers Club, the American Pakistan Foundation, and was a former advisory board member for Thomson Safaris.^[24][25] O'Brien has contributed to a number of research and scientific projects including investigating the effects of nocturnal hypoxic exposure on high-altitude mountaineering (Explorers Club Flag No. 206 to Manaslu's summit at 26,759 feet^[26]), testing the thinning of high altitude glaciers (Explorers Club Flag #132 to the Godwin-Austen Glacier at 16,500 feet^[27]), and illustrating the impact of climate change at the equator in advance of COP21 in conjunction with Project 25Zero.^[28]

Vanessa is a global ambassador for iMedisync, a digital mental health care platform company, that provides early detection and treatment of MCI (mild cognitive impairment), dementia, Parkinson's and Alzheimer's Disease.^[29] O'Brien's use of MRI imaging pre and post spaceflights showed less activity in the Parietal Lobe indicating a loss of self, and a more connected or "at-one-with-the-world" state of mind.^[30]

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 (Shishapangma, Everest, Cho Oyu, Manaslu, and K2), including summiting two eight thousanders back-to-back just 8 days apart (Shishapangma and Cho Oyu), O'Brien decided to build on her passion for mountaineering and set herself the challenge of achieving the Explorers Grand Slam.^[31] The Explorers Grand Slam entails reaching the Seven Summits, the North and South Poles, as well as meeting the Three Pole Challenge.^[32]

O'Brien 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.^[33] On 12 June 2020, Victor Vescovo and O'Brien 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 (5.5 m), subject to verification.^[34]

O'Brien flew aboard Blue Origin NS-22, receiving FAA human spaceflight recognition, on 4 August 2022.^[35][1] For the sixth time in its 20-year history, Blue Origin successfully launched humans on a sub-orbital spaceflight on the New Shepard 22 mission. The five humans that flew with O'Brien included Coby Cotton, Mário Ferreira, Clint Kelly III, Sara Sabry, and Steve Young, flying to a height of 107 km above Mean Sea Level (351,232 ft MSL). The crew endured 3,603 km/h (2,239 mph) during ascent and flew for a total of 10 minutes and 20 seconds.^[36] This was the first spaceflight of Blue Origin involving two female crew members, and Vanessa O'Brien carried the UN Women's flag.^[3]

After taking the American Red Cross flag to the North Pole in 2013,^[32] O'Brien completed the Boston Marathon in 2017 to help the American Red Cross raise over $512,000 for charity.^[37][38]
