Planetary Landing Vehicles - System Basics

This article is about basic system requirements a planetary landing vehicle should fulfill in order to make successful landing. The past several decades numerous landing vehicles crashed, the most memorable to me being Beagle 2, which was lost on planet Mars. Recently several landers were lost too on the Moon - one of them was Beresheet, an Israeli lander.

So why is it that in the past few decades several of those landers didn’t make it while the technology they were carrying was much more advanced than it was in the 1950s to 1970s, when space technology was still in its infancy?

Well, according to my view not enough dedication to the fundamentals and basics of landing systems could be the reason.

In the 1960s a series of landers made it to the Moon without too much hassle, among them NASA’s Surveyor program and then the Apollo program. Those were the days with focus and insight on the basics and fundamentals. Technology those days was fundamental and pretty much radiation resistant for the simple reason that there wasn’t that much electronics in those landers - remember the highest high-tech in the Apollo landers was a “computer”, which failed during Neil Armstrong’s descent. Nonetheless, after reboot Armstrong landed safely.

Nowadays engineers and scientists tend to loose focus on the basics and find themselves digging and debugging millions of lines of code.

Now, let us focus on two landers, Beagle 2 and Beresheet.

At first in 2003 everyone believed Beagle had crashed on Mars and was lost right away as nothing was heard from the lander anymore -- ESA quit listening after some time. So the question rose, what went wrong with Beagle 2?

In 2005 an inquiry report was published hypothesizing and speculating on what the problem could’ve been.

And then in 2015 ... all of the sudden Beagle was found. According to the Guardian Beagle 2 was found on the surface of Mars after a successful landing - yes, successful, you read that right - but couldn’t communicate due to solar panels which didn’t deploy (properly enough)!!!  And that weakness was already pointed out in the inquiry report, section 5.4.8, last paragraph.

Yes, not properly deployed solar panels nicked Pillinger’s child, Beagle 2. And that raises questions about the design. Below is a picture clearly showing the joint or hinge of a solar panel.

The joint connects the solar panel to the body of the Beagle 2. This joint looks rather -- maybe too -- primitive and may very well be the cause of the blockage.

So they spent millions of dollars (or was it pounds) on a lander but then something goes wrong with the deployment of the solar panels?!

We all know that space is a hostile and rough environment, even for a space craft.  The journey -- the ride -- can go accompanied with extreme vibrations for any craft and with Beagle on a very tight budget they may have been cutting back on the mechanical strength of the Beagle too much so to save money.

The whole Beagle story raises the uncomfortable thought: was it tested enough? Could the designers not have foreseen that one particular solar panel would not open? And if so, that is would block the antenna?  Having a clear antenna to communicate is rather essential, and any scenario blocking the antenna should have been foreseen, tested for, and dealt with in advance.

Similar story with Beresheet.  It crashed due to failing gyroscopes (yes in plural). It looks like all gyroscopes failed!?  Usually one gyro can fail, but the remaining gyroscopes should survive, which wasn’t the case here; they all failed! Or was there just one gyroscope after all?

Nonetheless, with Beresheet a significant amount of resources went to a particular part of the payload from which it is clear that it did not add any scientific nor any technical value to the mission.  If that part of the payload would’ve been left out and its corresponding financial resources re-directed to the fundamentals and basics (read gyro’s) of the lander, then Beresheet would’ve made it for sure. Here too a critical inquiry would be appropriate, even more than in the case of the Beagle.

I can’t get rid of the feeling that the designers of both landers failed to focus on the robustness of the basics of the lander. It is absolute known in space industry that all sorts of things can go wrong and that keeping clear the critical components, like antennas and gyroscopes, is something that should’ve been on a checklist of “design for robustness”, or something like that.

I admit, the budget can be tight. However, one needs to prioritize and make a checklist with at the top the most important parts of your lander, in this case the basics and fundamentals of the lander itself. At the bottom of that checklist there are the accessories, very often being the scientific instruments, and at the very bottom stuff with no scientific or technical significance, which is then cut out first if budget restrains come into play.

So you devote the necessary resources to the basics and fundamentals in the lander so the agency can get proof of a successful landing. If then there are any resources left, those can be devoted to the accessories.

Devoting enough resources to the basics and fundamentals of the lander is of absolute priority. From the point of budget there can be no compromises with the accessories.

Very often resources that should’ve been destined or dedicated to the basics and fundamentals of a successful landing are being drained away for the scientific part on the lander, or even worse for that part to flatter national status.

It is understandable that on a tight budget the line of compromise is drawn so that less resources go to the lander itself and more for the scientific instruments. Big mistake!  Make no compromises!  Basics and fundamentals of the lander itself must come first and must have absolute priority!

Tardigrades, the toughest animals on Earth, have crash-landed on the moon

The tardigrade conquest of the solar system has begun.

The “library” was etched on to a nickel-metal disc, and it contained nearly all of English Wikipedia, copies of classic books, human blood samples, and tardigrades (because if anything alive on Earth is going to last billions of years, it’s them). Many of those tardigrades are coated in a protective resin, much like how amber preserves long-dead mosquitos that were once trapped in tree sap.

According to Wired, a co-creator of the library believes the disc survived the crash. “In the best-case scenario, Beresheet ejected the Arch Mission Foundation’s lunar library during impact and it lies in one piece somewhere near the crash site,” Wired reports.

It provokes a fascinating question: How long can those tardigrades survive on the moon?

Unfortunately Beresheet, Israel’s first spacecraft, suffered some communication problems & engine malfunctions during the landing process, and instead of landing on the moon it.... crashed on it. Oops :(

But hey, at least we’re ON it! And we got a moon selfie before she went down!

Beresheet, Israel's Lunar Lander, having taken some stunning photographs of the dark side of the moon (where we're glad to report there was no sign of the vile Roger Waters), is now in Lunar Orbit at a distance of approximately 470 Kilometers from the moon's surface. After a journey of over 3.4 million miles (5.5 million kilometres), the spacecraft is on schedule to touch down this coming Thursday (11th April) If successful, tiny Israel will become only the fourth country in history to land on the moon (after the USA, China and Russia) We wish them luck!

Texas Aerospace Firm Firefly To Use SpaceIL's Beresheet Lander Tech For NASA Moon Missions | Technology News

Firefly is set to build a new lunar lander based on the Israeli spacecraft's blueprints as part of a NASA program to deliver science payloads to the moon.

Israel’s Beresheet spacecraft (Hebrew for “Genesis”) may have crash-landed on the moon this April, but its innovative design and tech will serve as the basis for future lunar missions launched by Texas aerospace company Firefly Aerospace.

Firefly is set to build upon the Beresheet endeavor and create a new lunar lander based on the Israeli spacecraft’s blueprints as part of a NASA program to deliver science payloads to the surface of the moon. Firefly was one of nine companies selected by NASA to participate in the Commercial Lunar Payload Services (CLPS).

Israel’s first moon mission lost moments before landing

The spacecraft’s engine cut out just before it was to touch down in the Sea of Serenity.

Israel’s first lunar lander, Beresheet, appears to have crash-landed on the moon.

The spacecraft, launched by the Israeli nonprofit SpaceIL, was scheduled to touch down on the lunar surface on April 11. But in the final few minutes of its descent, the spacecraft’s engine stalled. Mission control reset Beresheet to bring its engine back online, but then communication with the lander cut out.

“#Beresheet's main engine fail! Spacecraft failed landing. Appeared to have crashed on the moon's surface!” the Israel Space Agency tweeted at 3:30 p.m. EDT.

“We didn’t make it, but we definitely tried,” said SpaceIL Chairman Morris Kahn in an online livestream of the landing. “I think we can be proud.”

Had Beresheet arrived safely, Israel would have become the fourth country — following the United States, the former Soviet Union and China — to stick a lunar landing (SN: 11/24/18, p. 14). Still, Israel has now claimed seventh place in sending a spacecraft into orbit around the moon.

Launched from Cape Canaveral, Fla., onboard a SpaceX rocket in February, Beresheet orbited Earth until meeting up with the moon in early April. After several lunar orbits, the spacecraft was set to park in the Sea of Serenity — a volcanic plain on the moon’s nearside, close to where Apollo 17 astronauts planted a flag in 1972.

Beresheet carried a handful of scientific instruments onboard, including cameras and a device to measure magnetic fields. But science was only SpaceIL’s No. 2 priority for their small, scrappy spacecraft. The primary goal of Beresheet was a successful landing that would help create an “Apollo Effect” to inspire Israeli students to pursue science and engineering. The mission even inspired a children’s book, The Little Spacecraft.

This isn’t the end for an Israeli mission to the moon, according to Israeli Prime Minister Benjamin Netanyahu. “If at first you don’t succeed, you try again.”
