Artemis II & Lunar Flashes
Artemis II
This mission is the first crewed deep-space mission in over 50 years! You can observe this historic launch with your Unistellar telescope:
- Set up your Unistellar telescope and connect it to the app, then switch to your home Wi-Fi and visit science.unistellar.com → Planetary Defense → Ephemeris.
- Find the cellphone icon on the right (if it has a greyed out eye it means the target isn’t visible yet). Select Artemis II, enter your location and observation time, and hit Generate to get the link back to your app.
- Reconnect your telescope, press Goto, confirm the settings : RA and Dec should be entered in the app for you. Hit “Save” and once the telescope is finished moving, you can begin the observation by hitting the “Record” button on your screen to record your observation.
- Then watch as it slews to the rocket in real time.
- Check the ephemeris if the target disappears then follow it again when it becomes visible, and experience the launch like never before. ✨
You can also observe Lunar Flashes with your Unistellar telescope alongside the Artemis II crew!
Near-Earth Asteroid Campaigns
2001 FD58
2001 FD58 is a near-Earth asteroid passing approximately 17 lunar distances from Earth on February 14th. The asteroid has a diameter somewhere between 500 and 1,100 meters. 2001 FD58 will be bright enough to observe starting on February 13th and will remain bright enough for the eVscope to see until February 25th.
Main-Belt Campaigns
2033 (Basilea)
2033 (Basilea) is a roughly 6km diameter asteroid located within the inner portion of the asteroid belt. Its name comes from the city of Basel in Switzerland.
3260 (Vizbor)
3260 (Vizbor) is a main-belt asteroid that is estimated to have a diameter between 7 and 16 km. Discovered in 1974, Vizbor is named after Yuri Vizbor, a Soviet bard.
1796 (Riga)
(1796) Riga is a massive main-belt, some 65-70 km in diameter. With an orbital period of about 6 years, Riga always maintains a distance from the Sun of a little over 3 AU. It poses no threat to Earth, but it is an interesting object to study nonetheless.
