The DESTINY+ team also presented a potential trajectory that would fly by #Apophis, then by #Phaethon, and then by #2024YR4.

But if this will be possible or not depends on the exact launch date out of Tanegashima.

The DESTINY+ (Demonstration and Experiment of Space Technology for INterplanetary voYage with Phaethon fLyby and dUst Science) mission by JAXA will perform a close 500-km flyby of asteroid 3200 Phaethon in 2029 and also sample its dust. Planned launch date is in 2025.

The mission will also be used to demonstrate low cost solar electric propulsion in deep space and innovative light-weight solar array panel technology.

Asteroid 3200 Phaethon gets within 20.9 million km of the Sun. Surface temps reach 750°C causing thermal decomposition of carbonates, Fe-sulfides, and phyllosilicates that release CO2, S2, and H2O gas, resp. The gas release from mineral decomposition likely causes dust ejection.

New observations reveal that Phaethon is now shedding more sodium gas than dust.
These minerals cause colorful meteor streaks. Watch them tonight.

#Geminids #Phaethon
3/n

Unlike most other meteor showers that are caused by earth ploughing thru the icy trails of comets, the Geminids are caused by the dusty and gaseous trail left behind by asteroid 3200 Phaethon.

Phaethon has a very eccentric 35-year orbit, getting close to the Sun halfway within Mercury's orbit. Its orbit crosses that of Mars, Earth, Venus and Mercury, but is not likely to impact Earth anytime soon.

Diameter: 5.8 km
Rotation period: 3.6 h

From the “Perspectives Files” : Geminid Meteor Shower Tonight; Best in 2023
Things are looking up for what promises to be the best meteor shower of 2023.

For those who are hoping to get a view of the peak of the Geminid meteor shower overnight tonight, it appears that about half of the contiguous (48) states will have clea

Spectral detection of these minerals strongly implies that gas release from mineral decomposition is capable of triggering dust ejection."

In Greek mythology, #Phaethon was the son of #Helios, the sun #god. One day, Phaeton asked his father to drive the chariot of the sun of through the heavens for a single day. Like many a new teenage driver, Phaeton was unable to control the horses of the sun chariot (too much horsepower), which came too near the earth and began to scorch it. As a result, law enforcement (i.e. Zeus) hurled a thunderbolt at Phaethon, and cause him to crash his chariot into the river. https://www.britannica.com/topic/Phaethon-Greek-mythology
