We Await the Indian Moon Landing

We are down to one spacecraft approaching the Moon’s south pole – India’s Chandrayaan-3 mission, which is expected to land as early as tomorrow. This is India’s second try for a Moon landing after the loss of Chandrayaan-2, so fingers crossed. Chandrayaan-1 also sent a probe that impacted the Moon, but that was the plan.

We shall see if Indian patience beats Russian bravado.

India Prime Minister Modi put a possible spin on the past missions. Regarding Chandrayaan-1, he said:

Chandrayaan-1 is considered to be a path-breaker among global lunar missions as it confirmed the presence of water molecules on the moon. It featured in over 200 scientific publications around the world.

Even the failed second mission has its successes:

Chandrayaan-2 was equally pathbreaking because data from the Orbiter associated with it detected the presence of chromium, manganese and sodium for the first time through remote sensing. This will also provide more insights into the moon’s magmatic evolution. The key scientific outcomes from Chandrayaan 2 include the first ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument and more. This Mission has featured in almost 50 publications.

I like the positive attitude.

Luna-25 Fails to Land (Properly) on the Moon

The message from Roscosmos was pretty bland:

During the operation, an abnormal situation occurred on board the automatic station, which did not allow the maneuver to be performed with the specified parameters.

Translated into normal speech, we learned that Luna-25 crashed during its attempted landing on the lunar surface.

This is a blow for Russia and Putin as well. The Soviet Union could threaten the world and run a terrific space program. The Russians are bogged down in Ukraine and unable to pick up a lunar program ceased about 50 years ago. It is sad to watch.

Roscosmos Director General Yury Borisov blamed the crash on Russia’s long absence from the Moon, stating,

The negative experience of interrupting the lunar program for almost 50 years is the main reason for the failures.

He may want to add corruption, economic sanctions, and horrible leadership to that list of reasons.

At least the Russian mission was able to share a few photos from orbit before it all ended.

The Moon’s south pole is still available for anyone who wants it. The Indian space program will give it a try this week. We can only wish them well as they fly over the Russian rubble.

A Day in Astronomy: The Launch of Voyager 2

On this day in 1977, NASA launched the Voyager 2 space probe from the Kennedy Space Center at Cape Canaveral in Florida to study the solar system’s outer planets as well as interstellar space beyond the Sun’s heliosphere.

The Voyager 2 space probe is still talking to us as it continues its journey beyond the planets with a special message for anyone it may encounter.

During its initial mission, the space probe provided us with many images from an little known region of our solar system, including the image below of Jupiter’s moon Europa.

Space Quote: If You Build It…Don’t Forget to Maintain It

“On average we have a $250 to $260 million dollar annual maintenance gap…Unplanned failures can have mission impacts, and the last thing we want to do is affect Artemis or some other significant mission.”

-Statement by NASA Facilities and Real Estate Division Director Eric Weiser regarding the maintenance of NASA’s infrastructure, as reported in The Register. He went on to say, “What that means is, on average, we’re renewing our infrastructure around every 200 years… A better number would be 60 to 80 years, and to do that we simply need more funding.” I know maintenance expenditures are boring, but this is no different than defense or highways. You get what you pay for, and also what you maintain.

A New View of the Moon

The first images from Russia’s Luna-25 mission have arrived. They show the far side of the Moon permanently hidden from those of us here on Earth.

The spacecraft is now orbiting the Moon, which was last done by the Russians back in 1976. The lander is expected to be on the lunar surface this Monday if all goes well.

For the sake of science (leaving politics out of it), let’s hope for a successful landing.
