- Mars, the crescent Moon, and Antares form a Triangle before dawn Monday and Tuesday mornings.
- Venus continues to shine brightly in the southwest after sunset, appearing nearly 30 degrees above the horizon until about 8pm local time. You cant miss it, point it out to viewers!
- Mon, Jan 20, astronauts Jessica Meir and Christina Koch will be outside the ISS again replacing batteries during a 6.5 hour spacewalk scheduled to begin 6:50 am EST. Look for coverage on NASA TV.
- NASA bids farewell to the exoplanet hunting Spitzer Space Telescope. Engineers will decommission the spacecraft on Jan 30 after more than 16 years, continuing to use some instruments once the supply of liquid helium to cool the telescope was exhausted. From an Earth trailing heliocentric orbit, it made some of the first studies of atmospheres of planets around stars beyond our solar system, discovered five of the seven Earth sized planets around star TRAPPIST-1

On This Day
- Jan 19, 2001: A leak in the equipment cooling the Mars Odyssey orbiter’s spectrometer in a JPL cleanroom was noticed on a public webcam. The project manage was alerted and the mission saved as well as a lot of extra cleanup.
- Jan 19, 2006: The New Horizons mission launches on a 9.5 year journey to Pluto.
- Jan 20, 2006: Happy 90th birthday Edwin “Buzz” Aldrin
- Jan 20, 1986: Uranus’ moons Cordelia & Ophelia discovered by Rich Terrile
- Kan 22, 1910: A 6.9kg meteorite fell on Vigarano, Italy. Its calcium-aluminum-rich inclusions found would aid in estimating the age of the solar system.
The crescent Moon, Mars and star Antares form a triangle in
the southeastern sky before dawn Monday and Tuesday morning.
Near Earth Objects (NEO)
lunar distance (LD) is the mean distance to the moon ~239k miles. Anything within 1 LD is newsworthy. For more information see NASA’s Center for Near Earth Object Studies

Sample rise/set times for 01/23/20
This information is best used to identify passes worth sharing or skipping. Those nearest overhead are closest, brightest, and longest. Check dates and times for each pass before sharing.
International Space Station (ISS)
- fair pass begins Mon 2020-01-20 18:34:35 EST from the SSW (210°) reaches 42°, enters Earth’s shadow 37° above the horizon 3 minutes later
- outstanding pass begins Wed 2020-01-22 18:35:11 EST from the WSW (243°) reaches 64°, enters Earth’s shadow 33° above the horizon 4 minutes later
- poor pass begins Fri 2020-01-24 18:36:30 EST from the W (273°) reaches 28°, enters Earth’s shadow 19° above the horizon 4 minutes later
- below trees pass begins Sun 2020-01-26 18:38:18 EST from the WNW (301°) reaches 17°, enters Earth’s shadow 14° above the horizon 3 minutes later
- below trees pass begins Tue 2020-01-28 18:40:12 EST from the NW (324°) reaches 13°, enters Earth’s shadow 12° above the horizon 2 minutes later
Atmospheric drag and other factors can and do cause orbits to change. See the European Space Agency supported Heavens Above for the latest pass predictions. Satellite pass gradings are based on altitude reached and duration of the pass. Higher altitude passes are closer to the observer and generally brighter as a result. Satellites other than ISS are much more difficult to spot.
