A Day in Astronomy: The Last Lunar Footprint

On this day in 1972, Apollo 17 commander Eugene Cernan was the last human to be on the Moon. He was the eleventh human to ever step on the Moon.

Here is the full crew of Apollo 17:

  • Eugene A. Cernan, Commander
  • Harrison H. Schmitt, Lunar Module Pilot
  • Ronald E. Evans, Command Module Pilot

Mr. Cernan, who passed away in 2017, was also part of the Apollo 10 mission that orbited the moon without landing (similar to the upcoming Artemis II mission).

With the successful orbit of the Orion spacecraft around the Moon this month, let’s hope the 50 year dryspell is finally over and the United States can again be the nation putting humans back on the lunar surface. Of course, we will be followed by others, including the Chinese. Yet it’s important the first space-faring nation get back in the game and restart the human exploration of the Moon, and then Mars soon thereafter.

Reuters: “Bezos’ Space Company Teams with Lockheed, Boeing for NASA Moon Lander Pitch

Jeff Bezos’ space company Blue Origin is partnering with Boeing Co and Lockheed Martin Corp to pitch a lunar lander to NASA as the agency seeks to send humans to the moon again, the companies announced on Tuesday. The joint moon lander proposal, led by Blue Origin, marks the companies’ second attempt to win a coveted moon lander contract as NASA seeks more options for getting astronauts to the lunar surface under its multibillion dollar Artemis program.

Western University: “‘Unexpected’ Space Traveller Defies Theories About Origin of Solar System

Researchers from Western have shown that a fireball that originated at the edge of the Solar System was likely made of rock, not ice, challenging long-held beliefs about how the Solar System was formed. Just at the edge of our Solar System and halfway to the nearest stars is a collection of icy objects sailing through space, known as the Oort Cloud. Passing stars sometimes nudge these icy travellers towards the Sun, and we see them as comets with long tails. Scientists have yet to observe any objects in the Oort Cloud directly, but everything detected so far coming from its direction has been made of ice. Theoretically, the very basis of understanding our Solar System’s beginnings is built upon the foundation that only icy objects exist in these outer reaches and certainly, nothing made of rock.

Universe Today: “ESA’s Upcoming Mission Will Tell us if Venus is Still Volcanically Active

The EnVision mission is ESA’s fifth medium-class mission to Venus. It’s being planned in a partnership between NASA and ESA, and NASA will be providing the synthetic aperture radar instrument, which will map the surface (much as Magellan did). In addition to the two radars, the orbiter will carry spectrometers to study the atmosphere and surface. They will monitor trace gases in the atmosphere and analyze surface composition. The idea is to look for surface changes that might be linked to signs of active volcanism. Along with the VERITAS and DAVINCI missions, EnVision should reveal all we need to know about volcanic activity on Venus.

Lunar Traffic Jam – Japan Heads to the Moon

While the Orion spacecraft was heading back to Earth, the Japanese HAKUTO-R Mission 1 lunar lander was on its way to the Moon. The name HAKUTO refers to the white rabbit that lives on the moon in Japanese folklore.

The Japanese private firm iSpace is behind the lunar mission, becoming the first private company to place a lander on the Moon. The lunar lander’s milestones are shown below, with the landing to occur next April.

Both the mission and payload are multinational. Investors in iSpace include the Development Bank of Japan, Suzuki Motor, Japan Airlines, and Airbus Ventures, which the payload includes items from the U.S. (including a NASA satellite looking for water), Canada, Japan (rover), and the United Arab Emirates (rover).

This should be the first of many iSpace lunar missions, demonstrating the role of commercial parties in the ongoing race back to the Moon.

Orion Has Returned

The Orion has landed, or splashed down to be more accurate. The Artemis I mission had a successful finish with the Orion capsule parachuting down into the Pacific at 12:40 p.m. EST today. At the time of this posting, the capsule was still afloat in the water while awaiting a review by engineers before being taken aboard the USS Portland.

Now we can start talking about Artemis II.
