On this day in 1969, two Apollo 11 crew members – commander Neil Armstrong and pilot Buzz Aldrin – became the first men to walk on the Moon. The two landed in NASA’s Eagle lunar module in the Sea of Tranquility and remained on the Moon’s surface for about 21 hours and 36 minutes collecting samples, placing scientific equipment, and photographing/filming the terrain. The astronauts also spoke with President Nixon while on the Moon.
You can rewatch the ABC News video feed here showing Neil Armstrong as he steps on the surface of the Moon and famously states, “That’s one small step for man, one giant leap for mankind.”

The recent James Webb Space Telescope (JWST) images included hot gas giant exoplanet WASP-96 b, with NASA noting that the space telescope “…has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.”
The same NASA article also noted that the Hubble Space Telescope had found the first evidence of water on a exoplanet back in 2013. So I thought I would dig out that earlier from the European Space Agency, titled “Hubble Finds Water Vapour on Habitable-Zone Exoplanet for the First Time“:
With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone by University College London (UCL) researchers in a world first. K2-18b, which is eight times the mass of Earth, is now the only planet orbiting a star outside the Solar System, or exoplanet, known to have both water and temperatures that could support life.
The parent star, K2-18, is 110 light years from Earth in the constellation of Leo. Maybe we can convince the ESA and others to take another look with the JWST, assuming it is not already on the list of many upcoming projects.

I think we are all eager for more amazing photos from the James Webb Space Telescope, but we need to remember that the space telescope has a long list of priorities and these were not simply random images. An international committee with representatives from NASA, the European Space Agency (ESA), the Canadian Space Agency (CSA), and the Space Telescope Science Institute (STScI) decided on the future work of the space telescope.
The committee has shared these five missions represented by the images already released to the public, indicating the JWST has been pretty busy already:
Carina Nebula: The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars several times larger than the Sun.
WASP-96b (spectrum): WASP-96b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.
Southern Ring Nebula: The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light-years away from Earth.
Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1787. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.
SMACS 0723: Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations.
So what else is planned? NASA believes the JWST can stay in operation for the next 5 to 10 years, so it has a fair amount of time to allocate to scientists. This link takes you to the 266 approved projects for the telescope’s first year, representing approximately 6,000 hours of JWST prime time and up to 1,231 hours of parallel time. For instance, during the first year you have “Exoplanets and Disks” projects such as:
Icy Kuiper Belts in Exoplanetary Systems;
Unlocking the Mysteries of the Archetype Sub-Neptune GJ1214b with a Full-Orbit Phase Curve;
A Search for the Giant Planets that Drive White Dwarf Accretion;
Tell Me How I’m Supposed To Breathe With No Air: Measuring the Prevalence and Diversity of M-Dwarf Planet Atmospheres; and
Diamonds are Forever: Probing the Carbon Budget and Formation History of the Ultra-Puffy Hot Jupiter WASP-127b.
That is just a sample, but you can see from some of that titles that the scientists are having fun. Expect hundreds of new discoveries this year resulting from these observations.
Dmitry Rogozin, the head of the Russian space agency Roscosmos (seal shown above), has been removed from this position. He has been in this position since May 2018. After his endless squabbles with NASA as well as juvenile behavior, relations between the two space agencies now have a chance to heal.
The new head of Roscosmos is Yuri Borisov, who was serving as a deputy prime minister in charge of Russia’s weapons industries. Sources call this a demotion for Mr. Borisov, who has not had luck with the ongoing war in Ukraine.
While Mr. Borisov’s posted credentials show no space program experience, if he can keep his temper in check and focus on space missions then the atmosphere will improve exponentially.

It wasn’t that long ago U.S. astronauts were completely dependent on Russian rockets to get to the International Space Station (ISS). NASA was paying about $60 million per seat on the Soyuz spacecraft. Well, times have certainly changed with SpaceX now ferrying astronauts, Boeing working on its own crewed Starliner capsule, and Northrop Grumman already helping with cargo.
Now NASA is mixing it up. NASA and Russia’s Roscosmos agreed this weak to place astronauts on the Soyuz again and cosmonauts on the SpaceX Dragon spacecraft. Bloombergreports NASA stated that such mixed crews “ensures there are appropriately trained crew members on board the station for essential maintenance and spacewalks.” In other words, with two launches to the ISS planned in September, a mixing of the crews will ensure some stability in space if only one makes it to the station. Not a bad idea.
Even with all the rhetoric and stunts taking place, it’s nice to see a little bit of common sense prevailing.
