Engineers are Still Troubleshooting Why Mars InSight’s Mole is Stuck and Won’t Go Any Deeper

NASA’s Mars InSight Lander was always a bit of a tricky endeavour. The stationary lander has one chance to get things right, since it can’t move. While initially the mission went well, and the landing site looked good, the Mole is having trouble penetrating deep enough to fulfill its mission.

This is Where Mars 2020 Rover is Heading. From this Picture, I Think You Can Guess Why

Get used to hearing the name “Jezero Crater.” It’s the landing site for NASA’s Mars 2020 rover. The 2020 rover is slated to launch in July 2020, and will land at Jezero Crater in February, 2021.

It’s pretty easy to see why NASA chose Jezero Crater for the next rover in their Mars Exploration Program (MEP). MEP is NASA’s long-term plan to explore Mars robotically. It includes rovers like Spirit, Opportunity, and MSL, the InSight Lander, orbiting spacecraft, and soon the 2020 rover.

NASA has chosen 11 American companies to help them build the next lunar landers that will carry humans to the surface of the Moon. The 11 companies will conduct studies and work on prototype landers in the coming years. It’s all part of NASA’s Artemis mission, and the mission’s 2024 date with the surface of the Moon.

Here’s Where Beresheet Crashed into the Moon

The Beresheet lander came oh-so-close to touching down on the surface of the Moon, but something went wrong and it didn’t make it. Now, thanks to the Lunar Reconnaissance Orbiter, the exact point of impact can be seen.

NASA’s 2024 Moon Mission is called Artemis, and Will Need an Additional $1.6 Billion in Funding

The Moon’s going to have more human visitors in the year 2024. NASA has announced that their mission to the Moon, which is named Artemis after the Greek goddess of hunting, has been advanced by four years, from 2028 to 2024. But there’s a catch: they need more dough to do it. $1.6 billion more.

Despite the Crash, SpaceIL is Going Back to the Moon with Beresheet 2

Beresheet, the unlikely lander built with donations to a non-profit group, crashed into the Moon. But that doesn’t mean it wasn’t a historic accomplishment in its own way. Now SpaceIL, the non-profit behind Beresheet, wants to send another lander to the Moon.

Scientists are Trying to Figure Out Why InSight’s “Mole” Can’t Dig Any Deeper

Engineers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are busy working with a replica InSight Lander to see if they can understand what’s blocking the lander’s mole.

The mole is the short name for the lander’s Heat Probe, which is hammering its way into the Martian surface. The Heat Probe is actually called the HP3, or Heat and Physical Properties Package. It’s designed to work it’s way as far as 5 meters (16.4 ft.) into the soil, where it will measure the heat flowing from the interior of the planet. Those measurements will tell scientists a lot about the structure of Mars, and how rocky planets formed.

But as reported last month, the probe is being blocked at about 30 cm (1 ft.)

The China National Space Administration (CNSA) has released some new photos and updated the world on their lunar rover mission. The Yutu-2 rover is working its way into the history books on the lunar far side, exploring the Von Karman crater. It’s third lunar day is now in the record books.

You’re in This Picture. It’s a Selfie Taken by SpaceIL’s Beresheet Lunar Lander on its Way to the Moon

Israel’s space program doesn’t get a lot of headlines. Israel itself is in the news a lot, but usually for other reasons. But they do have a space program, and right now they have a lander, called Beresheet, on the way to the Moon.

Land Heavier Payloads on Mars. Aim for the Ground and Then Pull up at the Last Moment

Deceleration of Mars Science Laboratory in Martian Atmosphere. Artist's Concept depicts the interaction of NASA's Mars Science Laboratory spacecraft with the upper atmosphere of Mars during the entry, descent and landing (EDL) of the Curiosity rover onto the Martian surface. EDL begins when the spacecraft reaches the top of Martian atmosphere, about 81 miles (131 kilometers) above the surface of the Gale crater landing area, and ends with the rover safe and sound on the surface of Mars some 7 minutes later. During EDL, the spacecraft decelerates from a velocity of about 13,200 miles per hour (5,900 meters per second) at the top of the atmosphere, to stationary on the surface. Credit: NASA/JPL-Caltech

In the coming decades, a number of missions are planned for Mars, which include proposals to send astronauts there for the first time. This presents numerous logistical and technical challenges, ranging from the sheer distance to the need for increased protection against radiation. At the same time, there is also the difficulty of landing on the Red Planet, or what is referred to as the “Mars Curse“.

To complicate matters more, the size and mass of future missions (especially crewed spacecraft) will be beyond the capacity of current entry, descent, and landing (EDL) technology. To address this, a team of aerospace scientists released a study that shows how a trade-off between lower-altitude braking thrust and flight-path angle could allow for heavy missions to safely land on Mars.
