India’s Crashed Lander is In This Picture, Somewhere

The Chandrayaan-2 lander, Vikram, attempted a landing September 7th (Friday the 6th in the United States), on a small patch of lunar highland smooth plains between Simpelius N and Manzinus C craters. Unfortunately the landing was not successful and location of the spacecraft has not been announced. The scene above was captured from an LROC Quickmap fly-around of the site, image width is about 150 kilometers across the center [NASA/GSFC/Arizona State University].

This image of the lunar highlands is from NASA’s Lunar Reconnaissance Orbiter. You’d need superhuman eyesight to spot it, but India’s crashed Vikram lander is in there somewhere. The lander attempted to land on the Moon on September 6th, but when it was only 2.1 km above the surface, within reach of its objective, ISRO (Indian Space Research Organization) lost contact with the spacecraft.

India has Located the Vikram Lander, But it’s Still not Communicating With Home

On Sunday (Sept. 8th), the Indian Space Research Organization (ISRO) announced that they had located Vikram, the lander element of their Chandrayaan-2 mission. The search began almost immediately after the space agency lost contact with the robotic spacecraft, which occurred moments before it set down on the lunar surface (on Friday, Sept. 6th).

Chandrayaan 2 Mission Loses Contact With Vikram Lander During Descent

Reflecting its growth as a global power, India has achieved some impressive progress in space lately. In the past decade, the Indian Space Research Organization (ISRO) has sent robotic spacecraft into orbit, to the Moon, and also to Mars. And today, they made their first attempt at a soft lunar landing by sending the Vikram lander towards the surface of the Moon.

This move would have made India the fourth nation in the world to land a spacecraft on the lunar surface. The landing sequence went as planned until the lander reached an altitude of 2.1 km (1.3 mi) above the surface. Unfortunately, communications with the lander was lost at that point and it is unclear whether the lander crashed. At the moment, the ISRO is analyzing data collected by the orbiter to determine what happened.

The Spaceline: an Elevator From the Earth to the Moon

Humanity’s future may lie in space, but getting out there is a very big challenge. In short, launching payloads into space from the bottom of Earth’s gravity well is quite expensive, regardless of whether or not reusable rockets are involved. And while some have suggested that building a Space Elevator would be a long-term solution to this problem, this concept is also very expensive and presents all kinds of engineering hurdles.

As an alternative, a pair of astronomy graduate students from the US and UK recommend an inspired alternative known as the Spaceline. This concept would consist of anchoring a high-tensile strength caple to the Moon that would extend deep within Earth’s gravity well. This would allow the free movement of people and materials between the Earth and Moon at a fraction of the cost.

By Continuously Watching the Moon, we Could Detect Interstellar Meteorites

When ‘Oumuamua crossed Earth’s orbit on October 19th, 2017, it became the first interstellar object to ever be observed by humans. These and subsequent observations – rather than dispelling the mystery of ‘Oumuamua’s true nature – only deepened it. While the debate raged about whether it was an asteroid or a comet, with some even suggesting it could be an extra-terrestrial solar sail.

In the end, all that could be said definitively was that ‘Oumuamua was an interstellar object the likes of which astronomers had never before seen. In their most recent study on the subject, Harvard astronomers Amir Siraj and Abraham Loeb argue that such objects may have impacted on the lunar surface over the course of billions of years, which could provide an opportunity to study these objects more closely.

How Do We Settle on the Moon?

Welcome back to our series on Settling the Solar System! Today, we take a look at the closest celestial neighbor to Earth. That’s right, we’re taking a look at the Moon!

Chances are, we’ve all heard about it more than once in our lifetimes and even have some thoughts of our own on the subject. But for space agencies around the world, futurists, and private aerospace companies, the idea of colonizing the Moon is not a question of “if”, but “when” and “how”. For some, establishing a permanent human presence on the Moon is a matter of destiny while for others, it’s a matter of survival.

Not surprisingly, plans for establishing a human settlement predate both the Moon Landing and the Space Race. In the past few decades, many of these plansa have been dusted off and updated thanks to plans for a renewed era of lunar exploration. So what would it take to establish a permanent human presence on the Moon, when could it happen, and are we up to that challenge?

Astrobotic is Going to Use a Vulcan Rocket For its Lunar Lander in 2021

In May of 2019, NASA’s Commercial Lunar Payload Services (CLPS) selected Astrobotic to fulfill a contract to deliver 14 payloads to the Moon by 2021. The Pittsburg-based aerospace company plans to do this using their Peregrine Lander, a robotic lunar spacecraft that is capable of delivering payloads to the Moon for the competitive price of $1.2 million per kilogram (~$544,300 per lbs).

To get the Peregrine lander and NASA’s payloads to the Moon, Astrobiotic recently announced that it would be relying on United Launch Alliance (ULA) to provide launch services. ULA will do this using their next-generation heavy-lift launch system known as the Vulcan Centaur rocket, which will also be the inaugural launch of this new vehicle.

When it Comes to Gamma Radiation, the Moon is Actually Brighter Than the Sun

The eerie, hellish glow coming from the Moon may seem unreal in this image, since it’s invisible to our eyes. But instruments that detect gamma rays tell us it’s real. More than just a grainy, red picture, it’s a vivid reminder that there’s more going on than meets human eyes.

It’s also a reminder that any humans that visit the Moon need to be protected from this high-energy radiation.

Hardy Tardigrades on Board Israel’s Beresheet Lander Probably Survived the Crash

When SpaceIL’s Beresheet lander crashed into the Moon, it was a bitter-sweet moment for Israel’s space exploration aspirations. The privately-built spacecraft was punching above its weight class by proceeding on its journey to the Moon. Unfortunately, it crashed, ending the dream.

But Beresheet carried some unusual passengers, as part of an unusual, yet visionary, sub-mission: tardigrades.

There May be Thick Ice Deposits on the Moon and Mercury

In addition to being the only solvent that is capable of supporting life, water is essential to life as we know it here on Earth. Because of this, finding deposits of water – whether in liquid form or as ice – on other planets is always exciting. Even where is not seen as a potential indication of life, the presence of water offers opportunities for exploration, scientific study, and even the creation of human outposts.

This has certainly been the case as far as the Moon and Mercury are concerned, where water ice was discovered in the permanently-shadowed cratered regions around the poles. But according to a new analysis of the data from the Lunar Reconnaissance Orbiter and the MESSENGER spacecraft, the Moon and Mercury may have significantly more water ice than previously thought.
