Half-time for MASCOT – half the journey is completed

On December 3rd 2014, the French-German MASCOT asteroid lander was launched with its carrier probe Hayabusa2 from Tanegashima, an island about 40 kilometres south of the Japanese mainland. With MASCOT halfway to its destination, we look back on all that has happened since the launch.

At the beginning of 2015, MASCOT's spare flight unit, the so-called Flight Spare (FS), was refurbished and made ready. On Earth, this identical 'twin' of the asteroid lander serves as a reference system for the flight unit, the Flight Model (FM). The spare unit underwent the same qualification tests as the flight model and can also be used for advanced unit tests that were no longer possible for the FM due to scheduling constraints. These additional tests mainly focused on getting the best possible performance out of the system and on precisely calibrating the parameters required for the landing in October 2018. To achieve this, the scientific instruments on MASCOT performed a series of measurements. read more

One last look - farewell, MASCOT

Applying the final layers of protection prior to the launch

The last adjustments have been made and the final functionality tests have been completed. Following the successful installation of MASCOT into the Hayabusa-2 spacecraft in Sagamihara, the final preparations have taken place at the Tanegashima launch complex in Japan. The attachment of the solar sails – carefully folded up above MASCOT for the launch – offers the last opportunity to see MASCOT.

Now, the development team must take a step back – it is a strange feeling. For two and a half years, we have been nurturing MASCOT, seeing it grow, teaching it plenty. But now it is time to let go, in the truest sense of the word, and send it on its difficult mission. Unfortunately, we cannot accompany it.

So how do you deal with the departure of an object that is not alive in a biological sense, yet contains the personalities of so many people who have guided it so dearly throughout its development? read more

First test on Japanese soil

Mascot

The MASCOT asteroid lander will be delivered to the Japanese space agency JAXA at the start of next year. It will be integrated into the Hayabusa2 spacecraft and prepared for launch, scheduled for late 2014. There is still a long way to go, but there is little time! read more
