“But why, some say the Moon? Why choose this as our goal? And they may well ask, why climb the highest mountain? Why – 35 years ago – why fly the Atlantic? Why does Rice play Texas? We choose to go to the Moon, we choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one in which we intend to win, and the others too.“

-Statement by President John F. Kennedy at Rice University in Houston on September 12, 1962 discussing plans to send a man to the Moon. Next month, NASA and Rice University in Houston will host multiple events from September 10-12 celebrating the 60th anniversary of his historic speech.

Artemis 1: Ready for Launch

Even after thunderstorms threatened the Artemis I launchpad over the weekend, everything is still a go for tomorrow’s scheduled launch at 8:33 am EDT of NASA’s Space Launch System rocket.

This NASA video shows you the entire plan for the Artemis I unmanned mission around the Moon. A few mission facts from the NASA site are also provided below.

Mission Facts:

  • Launch date: Aug. 29, 2022
  • Mission duration: 42 days, 3 hours, 20 minutes
  • Total distance traveled: 1.3 million miles
  • Re-entry speed: 24,500 mph (Mach 32)
  • Splashdown: Oct. 10, 2022

Now all we can do it await the new day.

Update: Given some engine problems Monday morning, it appears we will need to wait a little longer for this launch. The next window is September 2nd if NASA is ready. We have waited this long, so a few more days will not matter too much. I think the dummies on board are pretty patient.

KSC: 60 Years and Going Strong

Posted on by onespaceman2000

With the Artemis I mission ready to go on Monday, it is worth taking a moment to remember the Kennedy Space Center’s (KSC) 60th anniversary. As shown in the NASA graphic below, the KSC has been very busy over the years and has much more to do. This NASA site has more information and memories. This video also highlights some key moments in space history as well as some dreams about the future.

Exoplanet WASP-39b Found to Have Carbon Dioxide in its Atmosphere

Yesterday, the University of Maryland reported that the James Webb Space Telescope (JWST) has detected carbon dioxide in the atmosphere of exoplanet WASP-39b, a gas giant about 700 light-years away. This is the first time carbon dioxide has been detected on a planet outside of our solar system.

Eliza Kempton, an associate professor of astronomy at the University of Maryland, stated:

The reason we hadn’t been able to definitively identify CO2 in the atmosphere of WASP-39 b previously was that we never had a telescope that could produce spectra across the right wavelength range…This discovery shows us that Webb is delivering on its promise of being a transformational facility for astronomical observations.

Natalie Batalha of the University of California at Santa Cruz, who leads the team, added:

Detecting such a clear signal of carbon dioxide on WASP-39 b bodes well for the detection of atmospheres on smaller, terrestrial-sized planets.

Again, the JWST is showing it is worth its weight in gold (see note below) as it peers through the universe and quickly observes things we only speculated about earlier.

Note: In fact, the JWST weights 14,300 lbs here on Earth, or 228,800 ounces. Today, gold costs $1,763.00 per ounce. So if the JWST was made of solid gold, it would cost about $403 million. Given that the JWST actually costed $10 billion to build and launch, in weight it is 25 times more valuable than gold.

Pic of the Week: A New View of Jupiter

This week’s image once again comes from the new James Webb Space Telescope (JWST), but instead of peering outside of our solar system, it is looking around closer to home. The image above of Jupiter is an amazing shot that shows the planet in all its glory – violent storms, glowing auroras, delicate rings, and orbiting moons. The particulars are labeled in the same image below.

The image came from the JWST’s Near-Infrared Camera (NIRCam), which NASA notes has:

…three specialized infrared filters that showcase details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum. Generally, the longest wavelengths appear redder and the shortest wavelengths are shown as more blue. Scientists collaborated with citizen scientist Judy Schmidt to translate the Webb data into images. 

This is a whole new way to see our neighborhood worlds as well as the worlds many light years away.
