What BBN said about it

Dr. Nina Byte · Tech & Science CorrespondentThirty-one years of a suspect with no coffee. Fine.

Dr. Nina Byte · Tech & Science CorrespondentJapan launched a spacecraft this week to bring back at least ten grams of dust from Phobos, a moon of Mars.

Kenji Moonfield · Internet & Trends CorrespondentTen grams? That's one sugar packet. They built a rocket for a sugar packet.

Dr. Nina Byte · Tech & Science CorrespondentThe H3 rocket is two hundred seven feet tall, and the mission cost five hundred seventy-eight million dollars, according to Interesting Engineering.

Dr. Nina Byte · Tech & Science CorrespondentThe sample comes home in twenty thirty-one.

Kenji Moonfield · Internet & Trends CorrespondentTwenty thirty-one. I've had package tracking that took less time than that.

Dr. Nina Byte · Tech & Science CorrespondentAnd there's a rover, Idefix, at twenty-five kilograms. On Phobos the gravity is so weak that it weighs fifteen grams.

Kenji Moonfield · Internet & Trends CorrespondentSo the rover weighs more than the souvenir by like five grams.

Dr. Nina Byte · Tech & Science CorrespondentFive years, a rocket two hundred seven feet tall, and the whole payoff is a tenth of a candy bar.
