UPDATE 2 - Monday, 2023 February 27, 4:05 a.m. EST / 9:05 UTC: NASA has delayed the next launch attempt for the SpaceX Crew-6 mission until Thursday, 2023 March 2, 12:34 a.m. EST / 5:34 UTC.

UPDATE - Monday, 2023 February 27, 1:45 a.m. EST / 6:45 UTC: A Nominal Launch Scrub was declared 2 minutes and 14 seconds before the launch time of 1:45 a.m. EST / 6:45 UTC, due to a problem with the fluids used to ignite the launch. Next launch attempt could occur on Tuesday, 2023 February 28, 1:22:29 a.m. EST / 6:22:29 UTC; however, no decision has yet been made to take this particular launch opportunity.

Editor's Note: NASA Astronaut Warren “Woody” Hoburg, who started as a Student Rocketeer, is one of four astronauts to launch for a mission to the International Space Station (ISS), in a SpaceX Crew Dragon spacecraft, early on Monday Morning, 2023 February 27. The other astronauts in this SpaceX Crew-6 mission will be NASA Astronaut Stephen Bowen, Russian Cosmonaut Andrey Fedyaev, and an astronaut from the United Arab Emirates: Sultan Al Neyadi.

Woody Hoburg, a native of the North Hills section of Metropolitan Pittsburgh, was a student member of the Tripoli Rocketry Association, one of two major rocketry clubs for high-power model rocketry, in the United States. The author of the article about Woody Hoburg, which can be found at the following Internet link, is Kenneth J. Good, one of the club's early members and former President of the Tripoli Rocketry Association.

Citizen Science: Help NASA Find Exo-planets

Time-lapse of exoplanets orbit motion

NASA's Jet Propulsion Laboratory (JPL) is looking for help from Citizen Scientists in the continuing search for Exo-planets, planets beyond our Solar System. Whether you have your own telescope, or want to use a computer or smart-phone, JPL has a way for citizens to help in this important research.

Although begun in 2018, Exoplanet Watch has now been enhanced to make it easier for Citizen Scientists to help. While more than 5,000 Exo-planets have already been discovered, scientists estimate that there could be millions more just within our own Milky Way Galaxy.

Internet link to the NASA JPL Exoplanet Web-Site near the end of this blog-post.

With Exoplanet Watch you can learn how to observe exoplanets and do data analysis using software that actual NASA scientists use,” said Rob Zellem, the creator of Exoplanet Watch and an astrophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “We’re excited to show more people how exoplanet science is really done.”

Help NASA With Your Computer

Although Exoplanet Watch is only five years old, NASA actually has ten years of Exo-planet observations, collected from a small ground-based telescope south of Tuscon, Arizona. And, this year JPL will start collecting data from two more telescopes at the Table Mountain facility in Southern California.

These telescopes are used to search for Exo-planet Transits. Similar to a Solar Eclipse on Earth, an Exo-planet Transit occurs when an Exo-planet eclipses or transits the host star, slightly dimming the light coming from the host star for a short period of time.

You can use your computer or smart-phone to comb though data of Exo-planets already discovered by NASA. You would observe a particular Exo-planet to learn more about its orbit around the host star. This could help determine the time it takes for this Exo-planet to make one orbit. The more frequent an Exo-planet Transit often means that this planet is closer to the host star, and may be too close, and hence too hot, to harbor life.

But, once scientists know how often an Exo-planet orbits a star, the easier it is for them to know when that Exo-planet is available for further study. Scientists can then schedule observing time on a large ground-based telescope or a space telescope; such time is restricted and very competitive, as many scientists wish to use a particular large telescope.

Exoplanet Watch participants could also use the data to search for variations in the apparent brightness of stars. The brightness of such stars could be caused by solar flares or sunspots seen on the star. This would help scientists determine the variability of a particular star, before beginning the study of an Exo-planet circling the star.

Help NASA With Your Telescope

For amateur astronomers, or the occasional star-gazer, with their own telescope, you could possibly collect your own scientific data for Exoplanet Watch.

Of course, the larger telescope available to you, the more stars and potential Exo-planets you may be able to observe. However, even someone with a 6-inch / 15 centimeter reflector telescope could possibly search for Exo-planet Transits around hundreds of nearby stars.

Observations of a particular star, by several participants, are used to gain more information about that star. This is particularly useful if the different observers are in different parts of the world.

So, Exoplanet Watch is not just for Americans. NASA welcomes anyone in the world to participate in this important Citizen Science research.

AND, you can receive scientific credit for your work helping to discover a particular Exo-planet. An Exoplanet Watch policy states that for the first use of observations or analysis done by volunteers, those volunteers must be listed as co-authors on the published, scientific research paper.

I hope this program lowers barriers to science for a lot of people and inspires the next generation of astronomers to join our field,” said Dr. Zellem.
