"We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time."

We're counting down to 🥧#PiDay✨ with the math problems we use to explore space at @NASA.
Can you calculate how many of @OSIRISREx's circular sample pads had to touch the asteroid Bennu to meet the mission goal.
Take the #NASAPiDayChallenge at go.nasa.gov/piday
ALT In this cartoonish illustration, OSIRIS-REx descends on a purple, rocky surface. An inset shows a circular device with small circular pads. An arrow points to one of the pads and identifies it as a collection pad.
ALT OSIRIS-REx Pi Day Problem 2021: NASA’s OSIRIS-REx mission was designed to travel to an asteroid called Bennu and bring a small sample back to Earth for further study. To achieve its mission, the spacecraft needed to make contact with 26 cm2 of asteroid Bennu’s surface and collect millimeter-size particles using its "contact-pad samplers." These are 1.5-centimeter diameter circular pads of Velcro-like stainless steel. There are 24 pads on the mechanism designed to collect the samples. How many pads needed to make contact with Bennu's surface to meet the mission requirement? If all 24 pads contacted Bennu, how much asteroid surface area would the contact pads sample?

This image shows a top-down view of Bennu, with the camera pointed directly at its North Pole. A portion of the asteroid’s equatorial ridge and northern hemisphere are illuminated. It was taken on Mar. 4 from about 186 miles (300 km) away. More details: bit.ly/3uW0U4e

On April 7, I’ll take one last look at asteroid Bennu 🌑
I’ll spend ~4 hours capturing images from 2.4 miles (3.8 km), focusing on site Nightingale to see how Bennu’s surface was transformed by the sample collection event.

Save the date! I'll be leaving Bennu on May 10 — but it looks like I might get one last close-up with the asteroid before my journey back to Earth 🛰🌎

The samples from asteroid Ryugu in the re-entry capsule weigh about 5.4g! This greatly exceeds the the target yield of 0.1g (the amount required for the initial scientific analysis) set during the design of Hayabusa2.
