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.Continue reading “Despite the Crash, SpaceIL is Going Back to the Moon with Beresheet 2”
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.)Continue reading “Scientists are Trying to Figure Out Why InSight’s “Mole” Can’t Dig Any Deeper”
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.Continue reading “China’s Lunar Rover Wakes Up and Gets to Work for its 3rd Lunar Day”
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.Continue reading “You’re in This Picture. It’s a Selfie Taken by SpaceIL’s Beresheet Lunar Lander on its Way to the Moon”
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.Continue reading “Land Heavier Payloads on Mars. Aim for the Ground and Then Pull up at the Last Moment”
On January 2nd, 2019, China’s Chang’e-4 lander made a successful landing on the far side of the Moon. The China National Space Administration (CNSA) and the Chinese Lunar Exploration Program (CLEP) report that after 9 days on the surface, the mission is in good shape. The Yutu-2 rover has been deployed and has begun exploring the Von Karman crater.
CNSA has released some video of the mission, including a video of Chang’e-4’s historic descent. Thanks to the hard-working people at the Planetary Society, and to Andrew Jones who reports on the Chinese Space Program, we have a handful of new videos and images of the Chang’e-4’s mission to enjoy.Continue reading “Incredible Descent Video of the Chinese Lander to the Lunar Far Side”
NASA’s InSight lander has deployed its first instrument on the surface of Mars. On December 19th, the stationary lander used its robotic arm to deploy the SEIS (Seismic Experiment for Interior Structure), marking the first time a seismometer has been placed on the surface of another planet. This is a milestone for the mission, and one that comes well ahead of schedule.
InSight landed on Mars at Elysium Planitia on November 26th. Since then, it’s been checking out its immediate surroundings with its cameras to find the perfect spot to deploy the seismometer, and its other deployable instrument, the HP3 (Heat Flow and Physical Properties Package.) Mission planners allocated several weeks for instrument site selection, so this is well ahead of schedule.

A handful of spacecraft have used ion engines to reach their destinations, but none have been as powerful as the engines on the BepiColombo spacecraft. BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA.) It was launched on October 20, 2018, and has gone through weeks of in-flight commissioning. On Sunday it turned on its powerful ion thrusters for the first time.
“We put our trust in the thrusters and they have not let us down.” – Günther Hasinger, ESA Director of Science.
BepiColombo is a three-part spacecraft. It has two orbiters, the Mercury Planet Orbiter (MPO) built by the ESA, and the Mercury Magnetospheric Orbiter (MMO) built by JAXA. The third part is the Mercury Transfer Module (MTM), built by ESA. The MTM is the propulsion part of the spacecraft and contains the spacecraft’s four ion engines.
When you go on a camping trip, when is it really tough? When are you really roughing it?
It is really tough if there is no supply store and no facilities at the place you are going. If you have to bring everything with you in your car then that makes it tougher.
If there is a gas station, running water and cabins for rent, then it becomes more like a rest stop on the highway.
The moon is a continent-sized place that is cold and difficult. The Moon has frozen ice. What do we do when we seriously want to research a remote continent-sized place that is cold and difficult. The example of that is Antarctica. Antarctica has McMurdo Station and dozens of other research stations.
NASA’s OSIRIS-REx spacecraft has reached its destination and is now in orbit around asteroid Bennu. The spacecraft travelled for over two years and covered more than 2 billion kms. It will spend a year in orbit, surveying the surface of the Potentially Hazardous Object (PHO) before settling on a location for the key phase of its mission: a sample return to Earth.
