09/06/2022 – Ephemeris – Ongoing NASA Missions

September 6, 2022

This is Ephemeris for Tuesday, September 6th. Today the Sun will be up for 12 hours and 59 minutes, setting at 8:10, and it will rise tomorrow at 7:12. The Moon, 3 days past first quarter, will set at 3:11 tomorrow morning.

The Artemis I launch has been postponed until later this month. The next try will come no sooner than the 25th, or next month. Another launch that is delayed is the Psyche mission to the asteroid Psyche that was supposed to be launched last month on a Falcon Heavy rocket. The problem this time isn’t the rocket, but the satellite. There is a delay with delivery and testing of the software for the satellite. The launch this year would have used a Mars flyby for a gravitational assist to shorten the flight time. A launch next year would not have that advantage and would increase the flight time. On the 26th of this month the DART satellite will impact the tiny asteroid Dimorphos, that’s orbiting a larger asteroid Didymos, to test that method of planetary defense.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.

Addendum

Artemis I availability dates_Sep-Oct 2022

Artemis I availability dates for September and October 2022. As I understand it, launches on red dates would cause the Orion capsule to be in the Earth’s shadow for longer than 90 minutes. Gray dates would have the Orion Capsule land at night. Credit NASA. A cut & paste from Artemis I Mission Availability 2022-2023 (EST/EDT) pdf.

DART Mission

Schematic of the DART mission shows the impact on the moonlet of asteroid (65803) Didymos. Post-impact observations from Earth-based optical telescopes and planetary radar would, in turn, measure the change in the moonlet’s orbit about the parent body.
