Wisseed Sat is a nanosatellite owned by Wisseed-the terra and built by Task and MASUYAMA-MFG. A satellite for education purposes, Wisseed Sat carries the milk teeth of around a dozen children, following the Japanese tradition of throwing one's milk tooth up towards the roof after they have come off to wish for the growth of the new tooth.{{cite news |last=Yamauchi |first=Kouhei |date=August 2, 2024 |title=超小型衛星 地球周回へ |url=https://www.yomiuri.co.jp/local/tottori/news/20240801-OYTNT50205/ |language=ja |newspaper=The Yomiuri Shimbun |access-date=2024-08-04}} Wisseed Sat is planned to be launched by a SpaceX Falcon 9 rocket and will be carried to the International Space Station (ISS) on board the Cygnus NG-21 spacecraft.{{cite web |url=https://www.nasa.gov/mission/station/research-explorer/investigation/?#id=9280 |title=Wisseed Sat |publisher=NASA |access-date=2024-08-04}} Wisseed Sat will be deployed from the ISS on a later date.

Spacecraft

Wisseed Sat was developed by Task and MASUYAMA-MFG. Task is a newspace company founded by Daisuke Furutomo, an engineer who was a member of team Hakuto which competed in the Google Lunar X Prize.{{cite news |date=November 20, 2015 |title=民間資本で月面を目指す! 「HAKUTO」のメカエンジニアが語る日本のモノづくり |url=https://monoist.itmedia.co.jp/mn/articles/1511/20/news024.html |language=ja |newspaper=MONOist |access-date=2024-08-04}} MASUYAMA-MFG is a company based in Tottori Prefecture and was in charge of manufacturing the spacecraft parts. The spacecraft is a 10 cm size cube, or a 1U size CubeSat, and wighs less than 1.1kg. After completion, Wisseed Sat was passed on to the Japanese space agency JAXA on 19 April 2024 to be launched by SpaceX.{{cite press release|date=May 15, 2024|title=乳歯と子ども達の夢を載せた「ウィズシー ド衛星」の引き渡し式を筑波宇宙センターJAXAにて実施 今秋にNASAケネディー宇宙センターから打ち上げへ|url=https://prtimes.jp/main/html/rd/p/000000001.000141565.html|language=ja|publisher=Wisseed-the terra|access-date=August 4, 2024}}

Mission

Wisseed Sat carries the milk teeth of around a dozen children to space. In Japan, there is a custom for children to throw their own milk tooth up torwards the roof after they have fallen off, to wish for a healthy new tooth to grow. Wisseed Sat is inspired by that tradition and will fly the teeth all the way to space, to wish that the children will accomplish big things once they have grown up. The satellite is part of Wisseed academy, an education program run by Wisseed-the terra. Wisseed-the terra is an education company based in Tokyo. According to Wisseed-the terra, 'Wisseed' is a portmanteau of wisdom and seed.
